What Is Bitcoin Mining? CoinCodex

AM is the worst thing out there, except for everything else........

Down to my last 99 credits. This is when you start getting the fun messages. When you spend that last credit and that profile that isn't quite too good to be true looks at you and winks.
I have met in person I think two people on AM over the past 3 years. One was not a match, and the other I thought/think we match but we haven't been able to get together again. That is a whole different level of frustration.
I have also in that time probably had another dozen that I think were real people but the conversation just petered out and they ghosted.
Also, I've had about another dozen that I believe were scams. Ultimately, looking for me to provide gift cards, bitcoin, or money to help with their visa application. Some of those conversation went on for a really long time. (What can I say, I'm talkative and lonely. Bad combination sometimes. *laugh*)
There were also a few that I believe were real but they were escorts or sugar babies. One got so grumpy in our conversation. No way to win a new customer that way. Not that I can tell her how to do business.
And then the 'what-if' messages. In general I assume a collect message is a scam. One I did respond to was actually the one I met and we were a match(at least temporarily). So being lonely and wanting that intimate human interaction(just "hey you" in the IM is pretty damn powerful), I've been actively trying to meet new people.
So today I received a wink. It was someone I had winked also after looking at their profile. They also requested my key. It is just a face pic there but I like faces so I put mine there to help someone decide if they like how I look. I granted the key request and BING, a collect message. Well I haven't had a new connection in awhile sure, let's roll the dice. What if?
"Hi love how are you doing? Hope you're enjoying your Monday!"
Sure it is a pretty plain message but hey it isn't overtly a scammer. I reply.... And waiting.... And waiting... Geeze if send more I sound desperate.... I kept an interesting friendly response. I thought everyone loves windowless vans with strangers handing out candy. Do they not like candy?
And so now I wonder. Was I bit by the algorithm that knows my level of desperation? The geek in me would love to see the data mining they do and how it determines how to best drain our credits and encourage us to buy more. I see that offer of renewing popping up as my credit balance drops and I already know I'll be buying more.
But hey, what if?

Bitcoin Revolution App South Africa Patrice Motsepe Reviews – Scam Or Legit?Bitcoin Revolution App South Africa Patrice Motsepe Reviews – Scam Or Legit?

Bitcoin Revolution South Africa Patrice Motsepe” Are Patrice Motsepe Bitcoin rumors true? Did he invest in Bitcoin Revolution?
With the advent of Bitcoin, several Bitcoin mining and trading companies got established. Each company had one goal, and that was to mine Bitcoins and use them for trading. If done right, it could result in huge profits. The Bitcoin Revolution South Africa is one of the most prominent examples in this matter.

What is Bitcoin Revolution South Africa?

Known as the Bitcoin Revolution App, it was created in 2018 that emerged as the leading automatic trading system for bitcoins. The intriguing element about it is that if offers 0.01 faster trading and feedback signaling than the rest of the competitors in the market.
The system has been designed by a group of brokers. These brokers have been working in the Bitcoin industry for years and were familiar with the way things worked. Since they all knew how things were working with other Bitcoin software, the brokers joined together to create the ultimate software solution for Bitcoin mining, known as the Bitcoin Revolution.
One of the interesting elements that led to the creation of the Bitcoin revolution App is that the brokers were entirely sure about their algorithm's workability. According to them, it was a simple yet effective way to enhance investments via Bitcoin trading.

How Does it Work?

The Bitcoin Revolution App South Africa is available for all users for free. The reason? The greater the volume of the users using the software, the better the margins. In addition, the users only need to deposit an initial investment with the broker, and they will be directed to the settings for account set up and can begin instantly.

  1. Account opening
  2. Initial deposit needed for starting trading
  3. Selecting the broker to trade with
  4. Choosing trade settings. If you’re aware of how the trading works, you can choose custom settings. If not, then choose auto trades settings
  5. Keeping track of the performance on the trading software. Since the entire trading system of cryptocurrency is subjected to volatility, it’s better to start with low investment to bear the expense in any adverse circumstance.

Bitcoin Revolution South Africa Reviews

Not all Bitcoin trading software or companies offer competitive services. However, the Bitcoin Revolution has positive reviews in this matter.

Investing when you don't trust [that] your own judgement [lines up with popular trends]

At 37, better a little late then never, I finally understand I need to invest my money. I've read advice that "if you have expertise in a field, why not use that to inform what companies you invest in?"
Here's the problem: as a tech geek / early adopter I tend to get the technical fundamentals right, but bet on the wrong horse every time. I zig just before the general population zags. I know this about myself, so it makes me question how I could trust myself to pick investments.
For example, I invested a lot of time, and some of my money, on a pre-Android Linux phone and learning how to develop for it. A few months later, the first iPhone came out. Right idea, wrong timing - I missed the mobile app developer bandwagon by being too early. Of course I could have pivoted to the new platform, but rode the sinking ship instead. Plus my tightwad (now ex-)wife at the time wouldn't stand for me putting $$$ on a different smartphone so soon after "wasting" $$$ on a dud.
In 2010 I thought Facebook was crazy to turn down a $24B offer from Microsoft. I predicted that people my age and younger would soon become disillusioned with the platform and might start leaving it in droves. I predicted FB would become and remain an irrelevant cesspool of sh!tposts and political memes. Plus you know, privacy concerns and all that. Well you all know how that turned out both in what did happen and how little long term effect it has had on FB's market value.
In 2009 (post crash) I supported / encouraged my (now ex-)wife at the time in buying our first house, because I envisioned that entities able to buy up properties for cash, such as (foreign) investment firms and rental companies were going to soon start out-competing individuals for houses on the market. I think I thought the concerning half of every trend over 2010-2020 was going to take place in 2009-2011. That didn't happen (then), and when we wanted to move the house failed to sell; she still lives in it.
I was aware of Bitcoin from early on. I could have easily mined it when it was still energy efficient to do so on a PC (and I had a collection of powerful PCs for the time), but I thought it was foolishness and didn't want any part of it.
It's like that episode of King of the Hill where Peggy figures out that by following Bill around as he shops and seeing what he buys she can know what to invest in because Bill is such an "everyman." Except in my case maybe you should pass on the things I pick for myself.

Quantum-Proof Encryption?

Safing team -
What are your thoughts on so-called quantum-proof encryption?
  1. Is it possible?
  2. Are you planning on making it at some point?
  3. This would put you on the map.
Google has let slip recently that they have a quantum computer. Many people believe it's "not there yet", and won't be for a long time.
Here's a different perspective.
Most people don't understand what quantum computers are. They probably just think it's next-gen or something harmless like that, because they simply don't have a category for it.
However, for those who do understand what it is - in my case, I think I kind of understand it - find its implications completely terrifying and overwhelming.
Emotions are a funny thing. If I were to take the average Joe on the street and explain to them about how data tracking works, they'd be absolutely horrified.
For example, I could sit someone down and explain to them about how Google is invisibly present on nearly every website they visit. I could demonstrate this using uMatrix in real time. "Look! Here they are. (Click to the next website.) Here they are. (Click to the next website.) Here they are again. (Click.) Again."
And when they first realize this, they are horrified. I've seen it over and over again, because I tell anyone who will listen. They are so horrified, in fact, that their defense mechanisms kick in. The most common defense mechanism is to simply shut it off and forget it. They'll say, "Oh well, what can I do about it? Who cares what I buy on Amazon? I have nothing to hide. I'm boring. I don't do drugs, I'm not having an affair, I don't break the law."
But some have a different defense mechanism. They seek to understand it, in order to protect themselves. Here's a threat, so I have to "know thy enemy". These are the privacy geeks, who dive into this head first. You can see them on the privacy subs. They're trying to wrap their heads around it.
But eventually, something happens to them too. Eventually, they realize that the problem is far worse than even their fears imagined. They become paranoid and take extreme measures. Some go very far down this road.
Eventually, the paranoia leaves them exhausted and they reach their limit. They're spending half their waking moments studying it, following it, trying to understand it, trying to set their devices up with the latest and greatest thing that they think will protect them.
The more stable among them eventually realize that their paranoia is toxic, and they realize that they have to strike a balance. They know they have to begin to pick their battles and make some compromises. They realize their "enemy" is too powerful for them.
There is one thing, however, that people have come to trust. Encryption. If their traffic is encrypted, they "know" it's "safe". VPNs. The Tor browser and its layers of encryption.
But quantum computers could change that. I understand quantum computers like this...
Imagine a child at a sit-down restaurant with a kids' menu. On the back of that kids' menu is a maze. They try out one path, it reaches a dead end. So they go back and try a different path, but that too is a dead end. They keep trying paths until they finally get to the end of the maze.
Computers perform calculations that work similarly to the maze. They try one solution, then another, then another, then another, until finally, they get the solution. The attempts are linear: one solution attempt after another. Think of movies where they depict a computer trying to break a password. They show all the characters in the password, and they're flashing through all possible characters. Then suddenly, one of the characters stops flashing. That character is a T. The next one suddenly stops, and that's a 4. On and on it goes, until all the characters are locked in place.
This is how Bitcoin mining works, for example. It takes a LOT of processing power to complete a calculation that produces one Bitcoin. This helps control the supply of Bitcoins. (I wonder who's collecting these solutions?)
But a quantum computer doesn't work like that. It's not linear. A quantum computer can attempt every possible solution at once. In the maze, it can attempt every possible path at once. It can crack even a very long, very complex password instantly. It can mine a Bitcoin in a moment. Snap your fingers. Bitcoin. Snap your fingers again. Another Bitcoin. One computer. Nearly instantaneously.
A quantum computer could be powerful enough to break encryption in real time, no matter how complex. This capability is so powerful it blows the mind. And then there's DNA-based processors, which can multiply, which also allows them to try every solution at once. It just multiplies as many times as necessary. If quantum computers are finite, DNA computers could theoretically be infinite. I think. (But I won't pretend to totally grasp what we're talking about here.)
A quantum-based or DNA-based laptop could theoretically be more powerful than all the processors in the entire world on every computer, including super computers and all the servers, combined.
I have brought this up in privacy forums. The standard, defense-mechanism-based answer is, "But that's YEARS away! The capability just isn't there yet! Look at what the publicly-available information says about it!"
But we're talking about Google. They have secrets, don't they? They're invisibly present on almost every website we visit. Their power stems from the fact that most people have no idea that that's true. How it all works is proprietary. There's a lot of guessing going on. No one knows for sure.
But if Google has ANY secrets at all, wouldn't they keep the capabilities of their quantum computer secret? Isn't it kind of surprising that the public knows (and has already forgotten) that Google has a functioning quantum computer? So does IBM. What capabilities do these possess, which the public knows nothing about? I assume the capability is greater than the public knows.
Right now, Google is "cooperating" with China on AI. It is publicly known that China has made tremendous advances in quantum computing. Connect the dots.
A quantum computer, fully functioning, could break encryption in real time. With the resources Google has, especially when combined with the resources of the Chinese government, imagine what they could do. Google already has all the data. They could decrypt it ALL. And they could share it with the Chinese government, who I'm sure would be willing to pay any price for it.
If Google is willing to cooperate on AI with China, where's their red-line as a company? What line will they say, "Oh no, we wouldn't do that. It would be unethical." China has actual concentration camps. Just like the Nazis once did. They put Muslims there. They force people to have abortions, repress religions, and even force some people to donate their organs. At least, there seems to be solid evidence that these things are occurring. This is a country ruled by sociopaths who seek to take over the world.
Why would anyone ever trust Google to "don't be evil", when clearly they have no ethical scruples whatsoever? Google, as a company, is a sociopath. Completely heartless. They are willing to exploit people in secret and cooperate with the Chinese communist party and their military. Why? To make money. If that's true, what else would they be willing to do?
I don't know if there is or even could be any such thing as quantum-proof encryption. I'm extremely skeptical, personally. But if it does exist, or could exist, then we need it. And we need it like 10 years ago.
So - does it exist? Could it exist? Could SPN employ it?

"Swap" is Poised for Take-off


https://preview.redd.it/mnxeb74hk4j51.jpg?width=990&format=pjpg&auto=webp&s=32d152a7495971c10e1af12185abe5e77b61fd14

How popular is DeFi?
Link, known as the leader of the oracle machine, has increased by 305.19% for the past three months, with an investment return of 17,052%, climbing to the fifth spot in the cryptocurrency ranking list by market value in the short term;
Since its issuance, YFI, which has soared 350 times all the way, has attracted 630 million US dollars of investment in 5 days, and was even dubbed the next Bitcoin in this circle;
From Comp for lending, KNC and BAL, governance tokens for decentralized exchanges, to SNX which is a stable currency payment network, various governance tokens of the DeFi ecosystem have emerged in an endless stream, stirring the blood in the market.
Such a boom is not only reflected in the currency price, but also pushes the brand new DEX based on the AMM (automated market making) model an overnight hit. UniSwap, known as the next-generation casino, has surpassed the world's first-tier centralized exchanges such as Binance, OKex, and Huobi in user activity, daily trading volume, and daily turnover.
With the rapid rise of UniSwap, the DEX threat theory has once again triggered heated discussions among the media and communities in the blockchain industry.
DEX on the Rise
The success of UniSwap is by no means something accidental. As early as 2018 when centralized exchanges suffered the hacker theft one after another, Vitalik Buterin, founder of Ethereum, predicted that the future lay in decentralized exchanges and that Ethereum, by developing a "better" decentralized platform, could empower the cryptocurrency community to regain the dominance from the centralized cryptocurrency exchange.
To realize the decentralized concept of returning to users their asset ownership, geeks in the blockchain industry have made many attempts.
Kyber Network, Bancor, Balancer, 0X, Curvefi, etc. are all DEXs based on Ethereum blocks. For a long time, affected by the performance of Ethereum and cross-chain issues, these DEXs were once stagnant.
With the lessons learned from Ethereum DEX, newcomers to the DEX have focused on high performance, high TPS, and rich assets as the ultimate goal for product development.
Amid the DEX threat theory, major exchanges have deployed their own public chain DEX products in a response to their respective development strategies: Binance launched Binance DEX on its Binance Chain, and Bittrex Exchange unveiled Ethfinex on the Ethereum and EOSfinex on the EOS blockchain, two platforms where users can exchange for fiat currencies; last year, CoinEx officially launched CoinEx Chain, a public chain dedicated to decentralized transactions, followed by CoinEx DEX.
Since the birth of the DEX in the blockchain world, this field has never run out of competition.
By independent development or other’s advantage?
From 2017 when it was established to 2019 as it stabilized, DEX has witnessed its annual trading volume skyrocketing from less than US$5 million to over US$2.5 billion. As DeFi gains fame and grows rapidly, DEX has grown into the most popular source of money, attracting a flood of speculators. In the past month, the trading volume of the global cryptocurrency market DEX has exceeded US$ 4 billion, more than twice the figure across 2019.
In the past two years, despite the increasingly in-depth exploration in the DEX, the cross-chain issue remains a stumbling block in its development path. DEX will not outperform CEX in the trading experience until a cross-chain solution is worked out.
The concept of DeFi went viral in 2019. With the continuous improvement of the DeFi ecosystem, the current Ethereum blockchain has developed into a complete decentralized financial system, covering mortgage lending, interest from deposit, leveraged trading, token exchange, identity authentication, and other infrastructure essential to traditional financial systems.
In addition to the mouth-watering profit, the DeFi ecosystem has also brought along explosive growth in both the type and quantity of digital assets, making DEX a market favorite. Compared with the DEX dedicated to public chains, the Ethereum-based DEX has been equipped with more possible functions and thus become more attractive thanks to the comprehensive supplementary infrastructure on Ethereum.
This also presents DEX pioneers with new opportunities. Dubbed “Swap’s summer”, the summer of 2020 has seen a market rush in Swap development after UniSwap became a hit.
Miniswap, Justswap, and btswap are no more innovative than UniSwap according to their product structures and white papers.
By comparison, OneSwap has injected unique essence into its product design and governance model based on UniSwap's automated market making.
Upgraded UniSwap
OneSwap, which has a double mining model + order book, has received an investment of tens of millions from CoinEx even before the product is launched. It is known that OneSwap is jointly developed by a group of technology geeks who have engaged in the cryptocurrency community for many years. The project was initiated by a member of the team in an attempt to upgrade UniSwap after he experienced the convenient AMM enabled by UniSwap.
Without limit orders, users have to trade in the price set by the platform, which, however, compromised their experience. In addition, the lack of liquidity mining and transaction mining rewards cannot reduce the losses of liquidity providers caused by unilateral market conditions.
"DEX still has much room for perfection, and could even surpass CEX in trading experience"
The OneSwap development team always believes that UniSwap still has a long way to go before it becomes the strongest DEX in the DeFi ecosystem. They have endeavored to, relying on their abundant experience in exchange product development and digital currency trading, create the most powerful DEX product in the DeFi ecosystem based on smart contracts.
OneSwap is called the “upgraded UniSwap” in the community. By the combination of the Constant Product Market Maker (CPMM) model in the Uniswap project and the on-chain order book, it reduces restrictions on users’ trading, and, through its OneSwap Wallet, improves user interaction methods and further enhances their experience in trading and product usage.
OneSwap boasts one-click token issuance and listing essential to DEX. Unlike the listing review mechanism on Binance DEX, the setting of OneSwap is more consistent with the concept of decentralization. Anyone can put his or her good projects and ideas, if any, into practice through OneSwap without permission.
In terms of product design, OneSwap will add to its function menu the Candlestick chart, order form, and depth chart according to user habits, apart from limit orders. These functions will offer OneSwap users an experience as smooth, easy-to-use, and convenient as in the CEX.
A new source of money? A two-pronged platform with transaction mining + liquidity mining
To support on-chain governance, OneSwap will issue a ERC20 governance token called ONES. The total number of ONES remains constant at 100 million, 50% of which will be used as community funds to support the construction of the OneSwap ecosystem and 50% will be owned by the OneSwap team. Community funds can be applied for through on-chain governance. 5% of the part held by the team will be unlocked initially, and the rest will be unlocked at a rate of 5% every six months until all is unlocked after four and a half years.
After the OneSwap product was launched, the OneSwap team will take part of the initially unlocked tokens as airdrop rewards for the open beta. Then OneSwap will officially start liquidity mining and transaction mining, and the governance token ONES will also be simultaneously launched on centralized trading platforms across the world. The first round of mining activities will last for one month, and mining rewards are yet to be made public.
Liquidity mining is a popular way of obtaining governance tokens in the DeFi ecosystem. Well-known DeFi projects including COMP, Cure, and Banner have all enabled liquid mining.
Transaction mining could date back to 2018 when Fcoin grew popular.
The transaction mining model initiated by Fcoin in 2018 once set off a bull market that year, pushing many investors into financial freedom in the rush of transaction mining. In addition, transaction mining based on the DeFi ecosystem is still a blue ocean, which is not common in the current market. The success of OneSwap's double mining model, if possible, would surely start a craze in the cryptocurrency market.
The OneSwap team has not yet announced specific mining rules, but disclosed that it has developed the smart contract code. To ensure the product security, OneSwap will invite three well-known security agencies in the blockchain industry to audit the code and announce the auditing results in early September at the soonest.
Conclusion
DeFi did not rise to fame without reason in 2020. Such overnight popularity is an inevitable result of Ethereum's efforts to build a decentralized consensus mechanism and improve infrastructure in the past few years. Ethereum has almost become the only public chain in the DeFi circle and the only construction base for well-known DEX. If OneSwap succeeds, it means a huge breakthrough for both DeFi and Ethereum, and decentralization in its true sense is around the corner.

CPS (capricoin) to be the new king in defi!

CPS (capricoin) to be the new king in defi!

https://preview.redd.it/7ocji9v25ih51.jpg?width=732&format=pjpg&auto=webp&s=2805c69e1a1668b9dea7dfcbd297e210a9a1ef5f
With the recent popularity of the concept of defi, token in Ethereum ecology has gradually become an important asset category in cryptocurrency. In terms of the total amount of tokens, issuance, transaction time and transparency of smart contracts, these passes have both the characteristics of blockchain and the advantages provided by Ethereum, especially when Ethereum 2.0 is about to emerge. Ethereum erc20 protocol realizes "everyone can issue money", while DEX realizes "everyone can pay money".

It is needless to say that the prospect of defi decentralized finance is open, transparent and low threshold, which will reshape all aspects of traditional economic formats, so it is also known as "finance from the future". According to debank data, on August 12, the total market value of defi exceeded US $12 billion, while on August 10, the market value of defi just exceeded 10 billion, an increase of $2 billion or 20% in two days. In addition, the lock-in value of the defi ecosystem reached $5.5 billion, a record high.

https://preview.redd.it/t08ec7nf4ih51.jpg?width=600&format=pjpg&auto=webp&s=9cb2ee8292862762d6d8b47fe726a3c41f2eb572
In the current defi ecosystem, the main projects are basically focused on the decentralized lending of cryptocurrency, decentralized exchanges and other businesses, and there are few integrated service agreements based on decentralized finance. CPS (capricoin) ecological economy is a decentralized, private and democratic economy. If we design in a decentralized way, we believe that many departments will be improved and more efficient. Transaction costs can be greatly reduced, and the activities on the platform are more economical, more private and safer. In addition, the platform's defense against attacks is greatly improved. If you want to prevent attacks, you can shut down the network. CPS (capricoin) should break the Convention and become the breaker and leader of decentralized financial integration service agreement.

https://preview.redd.it/606kv77m4ih51.png?width=2111&format=png&auto=webp&s=31c4285984aab73c7a149084667e8c229509d8a0

CPS (capricoin) is the world's first distributed finance protocol based on blockchain, initiated by anonymous geek community. CPS is its token. Following bitcoin's steps, CPS (capricoin) advocates open source policy. Open source projects have a positive impact on sustainability because they support the principles of open communication, collaborative participation, peer review, rapid prototyping, transparency, elite management and community oriented development. It is these facilities that enable users and programmers to check, modify and consolidate the source code, and finally create it.
CPS (capricoin) will fully expand the target of defi and develop a new generation of decentralized digital finance technology. Based on the CPS (capricoin) ecology, we will create a decentralized financial aggregation platform, so as to help users achieve a full range of financial activities in the field of digital money and finance, and provide including but not limited to mining, lending, ABS, quantification, derivatives and other financial service agreements. By using smart contract and Oracle technology, CPS (Capricorn) distributed financial protocol has the advantages of faster transaction speed, higher security, lower threshold of participation and stronger decentralization attribute.

In the future, CPS (capricoin) will make full use of and give full play to the advantages of blockchain decentralization, create a credit system that cannot be built by traditional financial system, expand the ecosystem of CPS (capricoin), and help more users with financial needs obtain more convenient financial services.

Not only defi, the ambition of CPS (capricoin) is to build a specific financial system, so as to combine the current digital currency with modern finance, establish a set of decentralized financial rules, and establish a communication channel between the existing physical finance and digital money finance.

CPS (capricoin) believes that by establishing a complete set of autonomous financial system, realizing faster function iteration and upgrading with blockchain technology more in line with the future trend, and promoting more mature application and public chain development path, a new ecological transformation of decentralized finance is coming.

Hey. Whats the current deal with all this cryptocurrency stuff yo?

I remember when I first heard about cryptocurrency, reading about it as a concept on a couple of forums. The first time I heard it mentioned in RL was in hushed tones by some guys at a rave in about 2012. Soon after it seemed to become common talk among hippies, cypher nerds, libertarian idealists and drug dealers.
A couple of years pass and everyone is talking about bitcoin. Every news outlet and blog is raving about cryptocurrency. Bitcoin moons and suddenly allot of early investors are crazy rich. Bitcoin becomes pretty much a speculative commodity.
Now there is thousands of alternative cryptocurrencies, However the people I know who use/“trade” them now are no longer weirdos and geeks but seem to trade them much more in the same kind of compulsive way that people addicted to pokie machines or online gambling are.
I remember hearing about giant mining farms that burn tons of energy to mine minuscule fractions of crypto, the idea being that so long as crypto is perceived as being worth more than the energy being burned to mine it it’s profitable. There have been countless scandals with crypto startups.
Basically my question is, as someone only passively paying attention to this stuff, what is the current deal with cryptocurrency? Is it still going to destabilize global markets?(not that they really seem to need any help). Is it still Worth buying a few dollars worth of bitcoin every now and then as an investment or has it pretty much leveled out? What are your thoughts about current popular feeling about blockchain and cryptocurrency?

Bit off more than I can chew but still seeing it thru!

Let me first preface this with the following:
A: I am a musician/singehobbyist coder.
B: I have never used a jigsaw before.
C: I embarrassingly enough had to google how to properly read a ruler.
D: Router to me means, internet.
E: Home Depot can be scary for those who have no idea what they are doing.
F. Home Depot is even scarier when you find out you know more than the employee that is helping you.
G: MDF is heavier than you can ever imagine. Please please please bring a friend or two. I am not by any means weak. Each board is 96 lbs!
H: MDF is messy as hell!!! I had to dust my whole living room after putting plastic over everything and just routing 12 inches of the arcade to test my t-molding. (More on that later).
I: I am positive most of you out there will laugh at me thinking ,”What the hell was he thinking?” Well you know what? Fair enough.. I thought I was. And hey, I still built my dream arcade. Yes I took the long way but whatever....
So, let us begin on the journey.....
If you are here to just scan thru and find info on how to build your arcade quickly, please email me at [email protected] and ask me there. I will do my best to reply quickly. (Not very busy at the moment). Otherwise, hang on...it’s goin to be a VERY bumpy ride. At least it was for my jigsaw and router.
PART ONE: THE DREAM
I was born July 16 1974. I will never forget my first arcade. The sounds of all the machines going off at once. My Dad giving me a five dollar bill out of his brown corduroy jacket to get quarters was like I hit the jackpot. All 20 quarters barely fitting into my little hands, I felt rich!! This was also about the time the TV show Silver Spoons came out. I remember Ricky Schroeder having a few upright cabinets in his house. At that age I thought, ehh I’ll never have that. I grew up in the Southside of Chicago. Bridgeport. The land of Mayor Daley, Catholics and hot dogs. Arcade cabinets were for the wealthy and arcades, not for me. From then on, my Dad would take me to every arcade we could find, until they stopped. (I am 46 and we still play PlayStation 3 games together now that arcades are closed down). I have even learned how to code, 3D build in Blender and create my own VR arcades. But it’s not the same. So one day I spilled the beans to my wife who had no idea of my inner wanting.
PART TWO: HERE WE GO! It was around my 46th birthday when all of my family came together to help me purchase the gear to create my dream! My father in law helped me measure out the pieces but made me saw them with the jigsaw I borrowed. My real Dad is still in Chicago. I had the Home Depot guy cut the 8 x 4’ MDF into 5.5’ x 4’ MDF. Guess what? They still didn’t fit in the suv. So we roped them to the roof and rolled our windows down driving slow hoping they wouldn’t t fall off. Just like The Beverly Hillbillies!
We cut them outside at his home in the yard because I heard about how much dust it created and would be either evicted or divorced if I did that here.
Once we were done cutting:....
I piled all of the heavy pieces into my tiny Prius and lugged them up into our apartment. Before that, I must tell you where I got my plans.
Geekpub.com was who I settled on as I had been googling like crazy trying to find the easiest and best plans etc.. Mike on Geekpub is fantastic. However, if you are a noob like myself, message me. I was confused over a few things and ended up returning a lot of items back to Amazon that I never needed. No worries. Mike at GeekPub is a total pro with a pro workshop. He even mines his own Bitcoin!!!! He is my new hero. Anyways, he leaves a few things out that most of you would probably already know. (Which is why I’m sure he didn’t mention it). Like, never use water based paint for MDF. Always prime MDF. You don’t need a piano hinge for a full upright. Etc....
Mike made his arcade with cream of the crop gear. I had to improvise with only a jigsaw, router, drill and sandpaper. I bought brad nails but never used them. mike has a fancy air compressor nail gun he uses. I do not possess that. But, I DID use wood glue and pax MDF screws that I found at Home Depot and bought only because they said MDF! They contain their own bit to use which is a star shaped but.
It’s crazy how strong wood glue is. I glued a brace in the wrong spot and had to chisel it off 2 hours later!! Be careful and triple check. Take it from me!!! 
For your control panel Mike recommends Forstner bits for your control panel and I agree. Do yourself a favor and get these.
When it comes to routing out for the T Molding, I did it with a portable hand router. I DID purchase my bit on Amazon.
PART THREE: LEARN THY TOOLS
Ok so if you are going to borrow a router, find out the size of the shank before you order your bit for the t-molding slot. I originally ordered the 1/2 “ shank only to find out it needed the 1/4”. Also, take note or the size you need when ordering your t-molding!
Always rout from left to right. And again, if you are using MDF, mask your home with plenty of plastic. Make it look like in ET when they come to take home away. You’ll be glad you did!!!
If you are screwing into MDF, go slow and try to limit the times you have to re screw or else the wood fibers will split on you and your screw will just keep turning.
PART FOUR: PAINT
I haven’t started this yet but have learned a lot from researching other’s builds.
I learned to NEVER use water based anything on MDF as it will ruin it by swell.
I will add more info once I purchase my items from you know where.
I also made many mistakes by trying to saw a straight line with a jigsaw. No...I didn’t know about a straight edge guide.. Anyways, I just ordered a hand plane and I hope this will fix it. Will update soon!
Final -ish thoughts:
I’m positive I left out a bunch. I recommend you go to geekpub.com and buy the guild pass. I have zero affiliation with Mike. But am a big supporter as he does have quite a lot of knowledge. If you would like to just learn thru me, I can get you set and rolling with the knowledge that I have. [email protected]

Chromia - Blockchain of Blockchains That Has Staged To Revolutionize Decentralized Application Development

Blockchain has taken the world by storm. The tech may have been envisioned to power decentralized finance in Bitcoin, it's potential and use case had far exceeded such identity.
It has opened the possibility to develop trust and openness in a way that has never been expressed before.
However, like any new development, blockchain has many challenges that need to be addressed.
Firstly, existing protocols that power the initial set of blockchains are too slow to garner advanced real-world usage.
Their architectural build also implies they are unable to scale accordingly to meet application and usage demand.
Blockchains are renowned for their strong security and immutability, nonetheless, these factors rely solely on the type of protocol or consensus adopted, and in many cases, the consensus of a particular blockchain may fail to establish a secured environment that could be relied upon under factual circumstances.
On the developer end, developing and building blockchain applications is a nightmare many wanted to escape because most integrated blockchain programming languages are new with an unestablished root. This means programmers have to learn a new language from basics before they can start building on a blockchain network.
The hardest part is that almost each of every type and brand of blockchain has its unique programming language which as a result contributes to non-interoperability that led to a status quo of blockchains being called an "island of self-isolation".
An obvious solution to most of the aforementioned downsides is to start restructuring how blockchains are made by design and code.
The good news is that a blockchain project with a new root has already achieved the feat of addressing most of these problems by building a relational blockchain system governed by a management system termed "Postchain".
I am talking about Chromia blockchain network built by the ChromaWay development team.
Chromia
Chromia is a public blockchain with a relational database system build and design. What this means is that data can be structured and defined in any way by the builder of the system. This flexibility of data management allows for different usage scenarios.
This is a sweet pot for developers but what is more interesting is the ability to code and deploy applications in a seamless manner.
Chroma uses Postchain to oversee the operation of its blockchain network in conjunction with a flexible and easy-to-code programming language called RELL (Relational Language).
Great protocol design? Thumb up! Nice programming language... Interesting! But what about other challenges mentioned in the opening part of the post?
Hell yeah! A blockchain system cannot be duly considered if it can't scale and operate at a good speed.
Chromia takes this factor to heart and ensures its network is able to process transactions at a block rate of 2 seconds, which is more than enough to support most applications and commercial usage.
Blockchain Of Blockchains: Chromia Modular Configuration
One method spam is avoided on blockchain networks is through integrated fee structure, most times, this is charged directly from users. However, Chromia thinks this idea should be rewritten by instead charging Dapps directly for the operation they perform.
Consequently, and since most application usage differs from one type to another. This and many other implementations led to a modular blockchain design where each Dapp can reside on its own chain, dictate its own rule and usage and intended fee structure.
The Dapps in this case acts like side chains that are attached to the governing Chromia infrastructure. Each Dapp or side chain is independent but benefits from the security and laid facilities of the network.
Chromia adopted PBFT consensus to ensure consensus can be achieved under certain rules even if some node in the network cannot be relied upon at a time, thus, eliminating incidents such as 'one point of failure'.
An Infrastructure For A Wide Range Of Usage Scenario
Chromia launched its main net in Dec 2019, and moved from an experimental position to prove their dedication towards achieving their vision not just on paper but as a practical and working process.
Ever since their main net launch. The chain has seen different types of apps deploy on its network.
The network relational design also means Dapps with huge computational demand can work efficiently and seamlessly with any cause to worry.
Let's look at some of these Dapps.
Chromunity
A decentralized social media platform that leverages the advantage of the relational computational build of Chromia to bring about fantastic social and community user experience.
The advantages of Chromunity as a decentralized social platform is how users can control their data and interactions, vote for representatives that implement the will and voice of the community.
Chromunity features a Reddit-like design and interface with the ability to post short/long meaningful content to a wide range of community categories or specific ones.
These screenshots give a sneak peek into how the interactive user interface looks like.
Green Asset Wallet
This is the first enterprise Dapp to launch on the Chromia chain after its main net release.
Using the quote of how the project defines itself.
"Green Assets Wallet is the world’s first blockchain-based platform for easy validation and impact reporting of green bonds".
The product has many features that are designed to suit investor's needs. From real-time collaboration to ensuring optimum trust and transparency to security. The Dapp is ideal for green bonds operations that look to make issuer and investors' lives an easier one.
Investors have direct access to trusted green bond information, metrics, and data.
Green asset wallet at allows investors to make new investment discoveries through search criteria, compare, benchmark, and follow up on investment opportunities".
Issuers are able to operate with an independent, cost-efficient, and structured system, and provide investors with impact investment opportunities and report on achievements.
Mines Of Dalarnia
Is "an action-adventure platform-mining game where the player controls a character and guides them through various blocks of earth, to discover and collect minerals of multiple rarities. Includes a blockchain based real-estate market".
Chromia transaction speed and computational efficiency make it an ideal platform to build decentralized or blockchain games of different kinds.
Play Mines Of Dalarnia
Conclusion
Chromia combines many groundbreaking features that purport it as a new generation blockchain and set it out among the crowd.
It's easy to code programming language, Postchain consortium, relational database system express qualities that fit different needs of decentralized applications and their operations. All of which state the chain strength and confidence of usage.
Under the governance of ChromaWay - an organization of tech experts and geeks. Chromia is expected to continue on an upward positive momentum.
Learn more about the project from it's official website
Their Telegram group chat is a good place to start interacting with the community.
Chromia has a Twitter presence and their Whitepaper is a good reference and tool to have a good overview of the project mission and vision at large.

Source: Hasib Anwar, "Consensus Algorithms: The Root Of The Blockchain Technology"
The picture above shows 14 relatively mainstream consensus mechanisms summarized by a geek Hasib Anwar, including PoW (Proof of Work), PoS (Proof of Stake), DPoS (Delegated Proof of Stake), LPoS (Lease Proof of Stake), PoET ( Proof of Elapsed Time), PBFT (Practical Byzantine Fault Tolerance), SBFT (Simple Byzantine Fault Tolerance), DBFT (Delegated Byzantine Fault Tolerance), DAG (Directed Acyclic Graph), Proof-of-Activity (Proof of Activity), Proof-of- Importance (Proof of Importance), Proof-of-Capacity (Proof of Capacity), Proof-of-Burn ( Proof of Burn), Proof-of-Weight (Proof of Weight).
Next, we will mainly introduce and analyze the top ten consensus mechanisms of the current blockchain.
》DBFT
-Concept:
Delegated Byzantine fault tolerance. The improved Byzantine fault-tolerant algorithm makes it suitable for blockchain systems. The system consists of nodes, delegators (who can approve blocks), and speakers (who proposes the next block). It is a consensus algorithm that guarantees fault tolerance implemented inside the NEO blockchain.
-Principle:
In this mechanism, there are two participants: the professional bookkeeper "bookkeeping node" and the ordinary users in the system.
Ordinary users vote based on the proportion of holding stake to determine the bookkeeping node. When a consensus is required, a spokesperson is randomly selected from these bookkeeping nodes to draw up a plan, and then other bookkeeping nodes will vote basing on the Byzantine fault tolerance algorithm.That is, majority principle. If more than 66% of the nodes agree to the spokesperson’ plan, a consensus is reached; otherwise, the spokesperson is re-elected and the voting process is repeated.
-Representative application: Neo, etc.
》PoA
-Concept:
Proof of authority. That is, certified by some accredited accounts, these accredited accounts are called "validators". The software that the verifier runs that supports the verifier to place transactions in blocks.
-Principle:
Three conditions:
  1. The identity must be formally verified on the chain, and the information can be cross-verified in a publicly available domain;
  2. The qualifications must be difficult to obtain, so that the rights of the verification block obtained are precious enough;
  3. The authoritative inspection and procedures must be completely unified.
With PoA, every individual has the right to become a verifier, so there is an incentive to maintain the position of the verifier once acquired. By attaching a reputation to the identity, the verifier can be encouraged to maintain the transaction process. Because the verifier does not want to gain a negative reputation, it will lose its hard-won verifier status.
-Representative applications: VeChain, etc.
》DAG
-Concept:
Directed acyclic graph. Each newly added unit in the DAG is not only added to the long chain block, but added to all the previous blocks, verifying each new unit and confirming its parent unit and the parent unit of the parent unit, and gradually confirming until the genesis unit. As the hash of its parent unit is included in its own unit, the blockchains of all transactions are connected to each other to form a graph-like structure with time.
-Principle:
In the DAG network, each node can be a trader and a validator, because the transaction processing in DAG is done by the transaction node itself. Taking IOTA as an example, IOTA’s Tangle led
ger does not need to pay transaction fees while ensuring high-speed transaction processing. However, it does not mean that the transaction is free, because in this ledger, the initiation of each transaction needs to verify the other two random transactions first, and connect the transaction initiated by itself to these two transactions, so the responsibility that miners on the blockchain bear is distributed to all traders. The DAG method of processing transactions can be called asynchronous processing mode.

-Representative applications: IOTA, etc.
》PoET
-Concept:
Proof of elapsed time. That is, it is usually used in a permissioned blockchain network. It can determine the mining rights of the block holders in the network. The permissioned blockchain network requires any prospective participants to verify their identity before joining. According to the principles of the fair lottery system, each node is equally likely to become the winner.
-Principle:
Each participating node in the network must wait for a randomly selected period, and the first node to complete the set waiting time will get a new block. Each node in the blockchain network will generate a random waiting time and sleep for a set time. The node that wakes up first, that is, the node with the shortest waiting time, wakes up and submits a new block to the blockchain, and then broadcasts the necessary information to the entire peer-to-peer network. The same process will be repeated to find the next block.
Two factors:
  1. Participating nodes will naturally select a random time in nature, rather than deliberately;
  2. The winner did complete the waiting time.
-Representative application: HyperLedger Sawtooth, etc.
》PoSV
-Concept:
Proof of stake velocity. Proposed by Reddcoin, drawing on the concept of "money circulation speed" in economics, it mainly allocates bookkeeping rights based on the coin age of nodes participating in the competition.
-Principle:
PoSV also allocates accounting rights according to the coin age of the nodes participating in the competition, but modifies the coin age calculation formula to a function of exponential decay of growth rate. Taking Reddcoin as an example, Reddcoin sets the half-life of the coin age growth rate to 1 month. Assuming that the unit token can accumulate 1CoinDay coin age on the first day, only 0.5CoinDay coin age can be accumulated on the 31st day, and only 0.25CoinDay coin age can be accumulated on the 61st day, and so on. In this way, the nodes are encouraged to use the token to conduct a transaction after holding the token for a period of time, thereby restarting the calculation of the coin age and increasing the circulation speed of the token in the network.
-Representative applications: Reddcoin, etc.

Chapter 4 Summary of the Selection and Status Quo of Consensus Mechanism
4.1 How to choose a consensus mechanism that suits you
Step 1: Determine whether the final result is important
For some applications, the end result is very important. If you are building a new payment system that can support very small amounts, it is acceptable for the transaction result to change. Similarly, if you are creating a new distributed social network, 100% guarantee that the status is updated immediately is not particularly necessary. On the contrary, if you are creating a new distributed protocol, the final result is critical to the user experience. For example, Bitcoin has a final confirmation time of about 1 hour, Ethereum has a final confirmation time of about 6 minutes, and Tendermint Core only has a final confirmation time of 1 second.
Step 2: Determine how fast the application process needs to be
If you are building a game, is it reasonable to wait 15 seconds before each action? Due to the low block processing time of Ethereum, games built on it will cause poor user experience due to Ethereum's throughput. However, the application for the transfer of housing property rights can be run on Ethereum. Use the Cosmos SDK to build an application that allows developers to freely use Tendermint Core. It has a short block processing time and high throughput, and is capable of processing 10,000 transactions per second. You can reduce the required communication overhead and speed up the application by setting the maximum number of validators for the application.
Step 3: Determine the application's demand for decentralization
Some applications such as games may not require very high censorship resistance as a by-product of decentralization. In theory, does it really matter that the validator can create a cartel in the game and reverse the transaction result for profit? If it is not important, a blockchain such as EOS may be more suitable for your needs because of the fast transaction speed and free fees. However, some applications such as autonomous banks are more powerful and decentralized. Although Ethereum is considered to be decentralized, some supporters claim that Ethereum's mining pool is an important part of centralized platform, although there are actually only 11 validators (mining pools). One of the major benefits of building your own blockchain instead of building on a smart contract platform is that you can customize the way the application completes verification. However, it is difficult to build your own blockchain, so the Cosmos SDK is very useful, you can easily build your own blockchain and customize the degree of decentralization you need.
Step 4: Determine whether the system can be terminated
If you are building a new application similar to a distributed ride-sharing service, then ensuring 24/7 service must be the first priority, even if there are occasional errors in accounting similar to transactions. One of the properties of Tendermint Core is that if there is a disagreement between network validators, the network will suspend operations instead of proceeding erroneous transactions. Applications such as decentralized exchanges require correctness at all costs-if there is a problem, it is far better to suspend trading on the decentralized exchange than there may be trading problems.
Summary: Choose a suitable consensus algorithm after weighing the advantages and disadvantages
All in all, there is no single best consensus algorithm. Each consensus algorithm has its own value and advantages. You need to have your own judgments and choices. However, by understanding the relevant processes of the consensus mechanism, including proposals and agreements, and establishing a framework to consider the types of consensus algorithms that your application may require, you should be able to make wiser decisions.
4.2 Future development of consensus mechanism
The consensus algorithm is one of the core elements of the blockchain. Although there are more than 30 consensus mechanisms listed in the article, there are still many niche consensus mechanisms that may not be discussed. As the blockchain technology is gradually known and accepted by the public, more and more newer and better consensus algorithms may appear in the future, which may be brand-new consensus algorithms, and more should be improvement and optimization version based on the current consensus algorithm.
After 2016 and 2017 years’ fast development, the current consensus algorithm does not have a recognized evaluation standard, but is generally more biased towards fairness and decentralization, as well as some technical related issues, such as energy consumption and scalability , Fault tolerance and security, etc. However, blockchain technology must be combined with requirements and application scenarios, and the consensus mechanism algorithm and incentive mechanism are inseparable. How to customize a suitable consensus mechanism according to the characteristics of your own project and optimize the current consensus mechanism will become the future direction of consensus mechanism development
CelesOS
As the first DPOW financial blockchain operating system, CelesOS adopts consensus mechanism 3.0 to break through the "impossible triangle", which can provide high TPS while also allowing for decentralization. Committed to creating a financial blockchain operating system that embraces supervision, providing services for financial institutions and the development of applications on the supervision chain, and formulating a role and consensus ecological supervision layer agreement for supervision.

Next, we will mainly introduce and analyze the top ten consensus mechanisms of the current blockchain.
》POW
-Concept:
Work proof mechanism. That is, the proof of work means that it takes a certain amount of computer time to confirm the work.
-Principle:
Figure 7 PoW work proof principle
📷
https://preview.redd.it/xupacdfc4db51.png?width=554&format=png&auto=webp&s=3b6994641f5890804d93dfed9ecfd29308c8e0cc
The PoW represented by Bitcoin uses the SHA-256 algorithm function, which is a 256-bit hash algorithm in the password hash function family:
Proof of work output = SHA256 (SHA256 (block header));
if (output of proof of work if (output of proof of work >= target value), change the random number, recursive i logic, continue to compare with the target value.
New difficulty value = old difficulty value* (time spent by last 2016 blocks /20160 minutes)
Target value = maximum target value / difficulty value
The maximum target value is a fixed number. If the last 2016 blocks took less than 20160 minutes, then this coefficient will be small, and the target value will be adjusted bigger, if not, the target value will be adjusted smaller. Bitcoin mining difficulty and block generation speed will be inversely proportional to the appropriate adjustment of block generation speed.
-Representative applications: BTC, etc.
》POS
-Concept:
Proof of stake. That is, a mechanism for reaching consensus based on the holding currency. The longer the currency is held, the greater the probability of getting a reward.
-Principle:
PoS implementation algorithm formula: hash(block_header) = Coin age calculation formula: coinage = number of coins * remaining usage time of coins
Among them, coinage means coin age, which means that the older the coin age, the easier it is to get answers. The calculation of the coin age is obtained by multiplying the coins owned by the miner by the remaining usage time of each coin, which also means that the more coins you have, the easier it is to get answers. In this way, pos solves the problem of wasting resources in pow, and miners cannot own 51% coins from the entire network, so it also solves the problem of 51% attacks.
-Representative applications: ETH, etc.
》DPoS
-Concept:
Delegated proof of stake. That is, currency holding investors select super nodes by voting to operate the entire network , similar to the people's congress system.
-Principle:
The DPOS algorithm is divided into two parts. Elect a group of block producers and schedule production.
Election: Only permanent nodes with the right to be elected can be elected, and ultimately only the top N witnesses can be elected. These N individuals must obtain more than 50% of the votes to be successfully elected. In addition, this list will be re-elected at regular intervals.
Scheduled production: Under normal circumstances, block producers take turns to generate a block every 3 seconds. Assuming that no producer misses his order, then the chain they produce is bound to be the longest chain. When a witness produces a block, a block needs to be generated every 2s. If the specified time is exceeded, the current witness will lose the right to produce and the right will be transferred to the next witness. Then the witness is not only unpaid, but also may lose his identity.
-Representative applications: EOS, etc.
》DPoW
-Concept:
Delayed proof of work. A new-generation consensus mechanism based on PoB and DPoS. Miners use their own computing power, through the hash algorithm, and finally prove their work, get the corresponding wood, wood is not tradable. After the wood has accumulated to a certain amount, you can go to the burning site to burn the wood. This can achieve a balance between computing power and mining rights.
-Principle:
In the DPoW-based blockchain, miners are no longer rewarded tokens, but "wood" that can be burned, burning wood. Miners use their own computing power, through the hash algorithm, and finally prove their work, get the corresponding wood, wood is not tradable. After the wood has accumulated to a certain amount, you can go to the burning site to burn the wood. Through a set of algorithms, people who burn more wood or BP or a group of BP can obtain the right to generate blocks in the next event segment, and get rewards (tokens) after successful block generation. Since more than one person may burn wood in a time period, the probability of producing blocks in the next time period is determined by the amount of wood burned by oneself. The more it is burned, the higher the probability of obtaining block rights in the next period.
Two node types: notary node and normal node.
The 64 notary nodes are elected by the stakeholders of the dPoW blockchain, and the notarized confirmed blocks can be added from the dPoW blockchain to the attached PoW blockchain. Once a block is added, the hash value of the block will be added to the Bitcoin transaction signed by 33 notary nodes, and a hash will be created to the dPow block record of the Bitcoin blockchain. This record has been notarized by most notary nodes in the network. In order to avoid wars on mining between notary nodes, and thereby reduce the efficiency of the network, Komodo designed a mining method that uses a polling mechanism. This method has two operating modes. In the "No Notary" (No Notary) mode, all network nodes can participate in mining, which is similar to the traditional PoW consensus mechanism. In the "Notaries Active" mode, network notaries use a significantly reduced network difficulty rate to mine. In the "Notary Public Activation" mode, each notary public is allowed to mine a block with its current difficulty, while other notary public nodes must use 10 times the difficulty of mining, and all normal nodes use 100 times the difficulty of the notary public node.

》PBFT
-Concept:
Practical Byzantine fault tolerance algorithm. That is, the complexity of the algorithm is reduced from exponential to polynomial level, making the Byzantine fault-tolerant algorithm feasible in practical system applications.
-Principle:
Figure 9 PBFT algorithm principle

First, the client sends a request to the master node to call the service operation, and then the master node broadcasts other copies of the request. All copies execute the request and send the result back to the client. The client needs to wait for f+1 different replica nodes to return the same result as the final result of the entire operation.
Two qualifications: 1. All nodes must be deterministic. That is to say, the results of the operation must be the same under the same conditions and parameters. 2. All nodes must start from the same status. Under these two limited qualifications, even if there are failed replica nodes, the PBFT algorithm agrees on the total order of execution of all non-failed replica nodes, thereby ensuring security.
-Representative applications: Tendermint Consensus, etc.

Bitcoin fees: congestion manager

Bitcoin fees: congestion manager
The bitcoin mempool transaction queue is messy and too many people are jumping the line, congesting whoever is behind. Let’s organize that mess. No randomly jumping in front of the line no more! Rather squeeze in and dance with the queue. Forget about physical distancing! Squeeze, and don't let that range of fees grow out of control!
Please meet our traffic controller officer at: Bitcoin Congestion Manager
Bitcoin Congestion Manager
The following is for geeks:
The aim is to organize the queue by spoting non-uniformity on the mempool fee distribution and suggest fees for new transactions that would fill that gap. Over time that produces a somewhat smooth fee distribution and a much more predictable fee market where parties can trully prioritize transactions, and thus have liveness on Bitcoin.
It is mempool depth-based (i.e., queue position), it is reactive. It uses recent past incoming transaction flows, and mined transcation outflows, to estimate velocities parametric on mempool queue position. Based on block poisson statistics it then estimates when on average a transaction paying a given fee will be mined. Error is multiplicative, so if you rely on these for liveness, please stay right at the surface.
We don't have logs. The backend was commitioned by a client over 2 years ago, and it is open-source. We are serving it at our own costs, but it would be nice to eventually receive donations to cover the costs of running the full node server. Rest and websocket api provided. For live streaming of fees, please use the websocket api!

Crypto Banking Wars: Can Non-Custodial Crypto Wallets Ever Replace Banks?

Crypto Banking Wars: Can Non-Custodial Crypto Wallets Ever Replace Banks?
Can they overcome the product limitations of blockchain and deliver the world-class experience that consumers expect?
https://reddit.com/link/i8ewbx/video/ojkc6c9a1lg51/player
This is the second part of Crypto Banking Wars — a new series that examines what crypto-native company is most likely to become the bank of the future. Who is best positioned to reach mainstream adoption in consumer finance?
---
While crypto allows the world to get rid of banks, a bank will still very much be necessary for this very powerful technology to reach the masses. As we laid out in our previous series, Crypto-Powered, we believe companies that build with blockchain at their core will have the best shot at winning the broader consumer finance market. We hope it will be us at Genesis Block, but we aren’t the only game in town.
So this series explores the entire crypto landscape and tries to answer the question, which crypto company is most likely to become the bank of the future?
In our last episode, we offered an in-depth analysis of big crypto exchanges like Coinbase & Binance. Today we’re analyzing non-custodial crypto wallets. These are products where only the user can touch or move funds. Not even the company or developer who built the application can access, control, or stop funds from being moved. These apps allow users to truly become their own bank.
We’ve talked a little about this before. This group of companies is nowhere near the same level of threat as the biggest crypto exchanges. However, this group really understands DeFi and the magic it can bring. This class of products is heavily engineer-driven and at the bleeding-edge of DeFi innovation. These products are certainly worth discussing. Okay, let’s dive in.

Users & Audience

These non-custodial crypto wallets are especially popular among the most hardcore blockchain nerds and crypto cypherpunks.
“Not your keys, not your coins.”
This meme is endlessly repeated among longtime crypto hodlers. If you’re not in complete control of your crypto (i.e. using non-custodial wallets), then it’s not really your crypto. There has always been a close connection between libertarianism & cryptocurrency. This type of user wants to be in absolute control of their money and become their own bank.
In addition to the experienced crypto geeks, for some people, these products will mean the difference between life and death. Imagine a refugee family that wants to safely protect their years of hard work — their life savings — as they travel across borders. Carrying cash could put their safety or money at risk. A few years ago I spent time in Greece at refugee camps — I know first-hand this is a real use-case.

https://preview.redd.it/vigqlmgg1lg51.png?width=800&format=png&auto=webp&s=0a5d48a63ce7a637749bbbc03d62c51cc3f75613
Or imagine a family living under an authoritarian regime — afraid that their corrupt or oppressive government will seize their assets (or devalue their savings via hyperinflation). Citizens in these countries cannot risk putting their money in centralized banks or under their mattresses. They must become their own bank.
These are the common use-cases and users for non-custodial wallets.

Products in Market

Let’s do a quick round-up of some of the more popular products already in the market.
Web/Desktop The most popular web wallet is MetaMask. Though it doesn’t have any specific integration with DeFi protocols yet, it has more than a million users (which is a lot in crypto land!). Web wallets that are more deeply integrated with DeFi include InstaDapp, Zerion, DeFi Saver, Zapper, and MyCrypto (disclosure: I’m an investor and a big fan of Taylor). For the mass market, mobile will be a much more important form-factor. I don’t view these web products as much of a threat to Genesis Block.
https://preview.redd.it/gbpi2ijj1lg51.png?width=1050&format=png&auto=webp&s=c039887484bf8a3d3438fb02a384d0b9ef894e1f
Mobile The more serious threats to Genesis Block are the mobile products that (A) are leveraging some of the powerful DeFi protocols and (B) abstracting away a lot of the blockchain/DeFi UX complexity. While none get close to us on (B), the products attempting this are Argent and Dharma. To the extent they can, both are trying to make interacting with blockchain technology as simple as possible.
A few of the bigger exchanges have also entered this mobile non-custodial market. Coinbase has Wallet (via Cipher Browser acquisition). Binance has Trust Wallet (also via acquisition). And speaking of acquisitions, MyCrypto acquired Ambo, which is a solid product and has brought MyCrypto into the mobile space. Others worth mentioning include Rainbow — well-designed and built by a small indy-team with strong DeFi experience (former Balance team). And ZenGo which has a cool feature around keyless security (their CEO is a friend).
There are dozens of other mobile crypto wallets that do very little beyond showing your balances. They are not serious threats.

Hardware Wallets Holding crypto on your own hardware wallet is widely considered to be “best practice” from a security standpoint. The most popular hardware wallets are Ledger, Trezor, and KeepKey (by our friends at ShapeShift). Ledger Nano X is the only product that has Bluetooth — thus, the only one that can connect to a mobile app. While exciting and innovative, these hardware wallets are not yet integrated with any DeFi protocols.

Strengths

Let’s take a look at some of the strengths with non-custodial products.
  1. Regulatory arbitrage Because these products are “non-custodial”, they are able to avoid the regulatory burdens that centralized, custodial products must deal with (KYC/AML/MTL/etc). This is a strong practical benefit for a bootstrapped startup/buildedeveloper. Though it’s unclear how long this advantage lasts as products reach wider audiences and increased scrutiny.
  2. User Privacy Because of the regulatory arbitrage mentioned above, users do not need to complete onerous KYC requirements. For example, there’s no friction around selfies, government-issued IDs, SSNs, etc. Users can preserve much of their privacy and they don’t need to worry about their sensitive information being hacked, compromised, or leaked.
  3. Absolute control & custody This is really one of the great promises of crypto — users can become their own bank. Users can be in full control of their money. And they don’t need to bury it underground or hide it under a mattress. No dependence, reliance or trust in any third parties. Only the user herself can access and unlock the money.

Weaknesses

Now let’s examine some of the weaknesses.
  1. Knowledge & Education Most non-custodial products do not abstract away any of the blockchain complexity. In fact, they often expose more of it because the most loyal users are crypto geeks. Imagine how an average, non-crypto user feels when she starts seeing words like seed phrases, public & private keys, gas limits, transaction fees, blockchain explorers, hex addresses, and confirmation times. There is a lot for a user to learn and become educated on. That’s friction. The learning curve is very high and will always be a major blocker for adoption. We’ve talked about this in our Spreading Crypto series — to reach the masses, the crypto stuff needs to be in the background.
  2. User Experience It is currently impossible to create a smooth and performant user experience in non-custodial wallets or decentralized applications. Any interaction that requires a blockchain transaction will feel sluggish and slow. We built a messaging app on Ethereum and presented it at DevCon3 in Cancun. The technical constraints of blockchain technology were crushing to the user experience. We simply couldn’t create the real-time, modern messaging experience that users have come to expect from similar apps like Slack or WhatsApp. Until blockchains are closer in speed to web servers (which will be difficult given their decentralized nature), dApps will never be able to create the smooth user experience that the masses expect.
  3. Product Limitations Most non-custodial wallets today are based on Ethereum smart contracts. That means they are severely limited with the assets that they can support (only erc-20 tokens). Unless through synthetic assets (similar to Abra), these wallets cannot support massively popular assets like Bitcoin, XRP, Cardano, Litecoin, EOS, Tezos, Stellar, Cosmos, or countless others. There are exciting projects like tBTC trying to bring Bitcoin to Ethereum — but these experiments are still very, very early. Ethereum-based smart contract wallets are missing a huge part of the crypto-asset universe.
  4. Technical Complexity While developers are able to avoid a lot of regulatory complexity (see Strengths above), they are replacing it with increased technical complexity. Most non-custodial wallets are entirely dependent on smart contract technology which is still very experimental and early in development (see Insurance section of this DeFi use-cases post). Major bugs and major hacks do happen. Even recently, it was discovered that Argent had a “high severity vulnerability.” Fortunately, Argent fixed it and their users didn’t lose funds. The tools, frameworks, and best practices around smart contract technology are all still being established. Things can still easily go wrong, and they do.
  5. Loss of Funds Risk Beyond the technical risks mentioned above, with non-custodial wallets, it’s very easy for users to make mistakes. There is no “Forgot Password.” There is no customer support agent you can ping. There is no company behind it that can make you whole if you make a mistake and lose your money. You are on your own, just as CZ suggests. One wrong move and your money is all gone. If you lose your private key, there is no way to recover your funds. There are some new developments around social recovery, but that’s all still very experimental. This just isn’t the type of customer support experience people are used to. And it’s not a risk that most are willing to take.
  6. Integration with Fiat & Traditional Finance In today’s world, it’s still very hard to use crypto for daily spending (see Payments in our DeFi use-cases post). Hopefully, that will all change someday. In the meantime, if any of these non-custodial products hope to win in the broader consumer finance market, they will undoubtedly need to integrate with the legacy financial world — they need onramps (fiat-to-crypto deposit methods) and offramps (crypto-to-fiat withdraw/spend methods). As much as crypto-fanatics hate hearing it, you can’t expect people to jump headfirst into the new world unless there is a smooth transition, unless there are bridge technologies that help them arrive. This is why these fiat integrations are so important. Examples might be allowing ACH/Wire deposits (eg. via Plaid) or launching a debit card program for spend/withdraw. These fiat integrations are essential if the aim is to become the bank of the future. Doing any of this compliantly will require strong KYC/AML. So to achieve this use-case — integrating with traditional finance —all of the Strengths we mentioned above are nullified. There are no longer regulatory benefits. There are no longer privacy benefits (users need to upload KYC documents, etc). And users are no longer in complete control of their money.

Wrap Up

One of the great powers of crypto is that we no longer depend on banks. Anyone can store their wealth and have absolute control of their money. That’s made possible with these non-custodial wallets. It’s a wonderful thing.
I believe that the most knowledgeable and experienced crypto people (including myself) will always be active users of these applications. And as mentioned in this post, there will certainly be circumstances where these apps will be essential & even life-saving.
However, I do not believe this category of product is a major threat to Genesis Block to becoming the bank of the future.
They won’t win in the broader consumer finance market — mostly because I don’t believe that’s their target audience. These applications simply cannot produce the type of product experience that the masses require, want, or expect. The Weaknesses I’ve outlined above are just too overwhelming. The friction for mass-market consumers is just too much.

https://preview.redd.it/lp8dzxeh1lg51.png?width=800&format=png&auto=webp&s=03acdce545cd032f7e82b6665b001d7a06839557
The winning bank will be focused on solving real user problems and meeting user needs. Not slowed down by rigid idealism like censorship-resistance and absolute decentralization, as it is with most non-custodial wallets. The winning bank will be a world-class product that’s smooth, performant, and accessible. Not sluggish and slow, as it is with most non-custodial wallets. The winning bank will be one where blockchain & crypto is mostly invisible to end-users. Not front-and-center as it is with non-custodial wallets. The winning bank will be one managed and run by professionals who know exactly what they’re doing. Not DIY (Do It Yourself), as it is with non-custodial wallets.
So are these non-custodial wallets a threat to Genesis Block in winning the broader consumer finance market, and becoming the bank of the future?
No. They are designed for a very different audience.

Chromia - Blockchain of Blockchains That Has Staged To Revolutionize Decentralized Application Development

Blockchain has taken the world by storm. The tech may have been envisioned to power decentralized finance in Bitcoin, it's potential and use case had far exceeded such identity.
It has opened the possibility to develop trust and openness in a way that has never been expressed before.
However, like any new development, blockchain has many challenges that need to be addressed.
Firstly, existing protocols that power the initial set of blockchains are too slow to garner advanced real-world usage.
Their architectural build also implies they are unable to scale accordingly to meet application and usage demand.
Blockchains are renowned for their strong security and immutability, nonetheless, these factors rely solely on the type of protocol or consensus adopted, and in many cases, the consensus of a particular blockchain may fail to establish a secured environment that could be relied upon under factual circumstances.
On the developer end, developing and building blockchain applications is a nightmare many wanted to escape because most integrated blockchain programming languages are new with an unestablished root. This means programmers have to learn a new language from basics before they can start building on a blockchain network.
The hardest part is that almost each of every type and brand of blockchain has its unique programming language which as a result contributes to non-interoperability that led to a status quo of blockchains being called an "island of self-isolation".
An obvious solution to most of the aforementioned downsides is to start restructuring how blockchains are made by design and code.
The good news is that a blockchain project with a new root has already achieved the feat of addressing most of these problems by building a relational blockchain system governed by a management system termed "Postchain".
I am talking about Chromia blockchain network built by the ChromaWay development team.
Chromia
Chromia is a public blockchain with a relational database system build and design. What this means is that data can be structured and defined in any way by the builder of the system. This flexibility of data management allows for different usage scenarios.
This is a sweet pot for developers but what is more interesting is the ability to code and deploy applications in a seamless manner.
Chroma uses Postchain to oversee the operation of its blockchain network in conjunction with a flexible and easy-to-code programming language called RELL (Relational Language).
Great protocol design? Thumb up! Nice programming language... Interesting! But what about other challenges mentioned in the opening part of the post?
Hell yeah! A blockchain system cannot be duly considered if it can't scale and operate at a good speed.
Chromia takes this factor to heart and ensures its network is able to process transactions at a block rate of 2 seconds, which is more than enough to support most applications and commercial usage.
Blockchain Of Blockchains: Chromia Modular Configuration
One method spam is avoided on blockchain networks is through integrated fee structure, most times, this is charged directly from users. However, Chromia thinks this idea should be rewritten by instead charging Dapps directly for the operation they perform.
Consequently, and since most application usage differs from one type to another. This and many other implementations led to a modular blockchain design where each Dapp can reside on its own chain, dictate its own rule and usage and intended fee structure.
The Dapps in this case acts like side chains that are attached to the governing Chromia infrastructure. Each Dapp or side chain is independent but benefits from the security and laid facilities of the network.
Chromia adopted PBFT consensus to ensure consensus can be achieved under certain rules even if some node in the network cannot be relied upon at a time, thus, eliminating incidents such as 'one point of failure'.
An Infrastructure For A Wide Range Of Usage Scenario
Chromia launched its main net in Dec 2019, and moved from an experimental position to prove their dedication towards achieving their vision not just on paper but as a practical and working process.
Ever since their main net launch. The chain has seen different types of apps deploy on its network.
The network relational design also means Dapps with huge computational demand can work efficiently and seamlessly with any cause to worry.
Let's look at some of these Dapps.
Chromunity
A decentralized social media platform that leverages the advantage of the relational computational build of Chromia to bring about fantastic social and community user experience.
The advantages of Chromunity as a decentralized social platform is how users can control their data and interactions, vote for representatives that implement the will and voice of the community.
Chromunity features a Reddit-like design and interface with the ability to post short/long meaningful content to a wide range of community categories or specific ones.
These screenshots give a sneak peek into how the interactive user interface looks like.
Green Asset Wallet
This is the first enterprise Dapp to launch on the Chromia chain after its main net release.
Using the quote of how the project defines itself.
"Green Assets Wallet is the world’s first blockchain-based platform for easy validation and impact reporting of green bonds".
The product has many features that are designed to suit investor's needs. From real-time collaboration to ensuring optimum trust and transparency to security. The Dapp is ideal for green bonds operations that look to make issuer and investors' lives an easier one.
Investors have direct access to trusted green bond information, metrics, and data.
Green asset wallet at allows investors to make new investment discoveries through search criteria, compare, benchmark, and follow up on investment opportunities".
Issuers are able to operate with an independent, cost-efficient, and structured system, and provide investors with impact investment opportunities and report on achievements.
Mines Of Dalarnia
Is "an action-adventure platform-mining game where the player controls a character and guides them through various blocks of earth, to discover and collect minerals of multiple rarities. Includes a blockchain based real-estate market".
Chromia transaction speed and computational efficiency make it an ideal platform to build decentralized or blockchain games of different kinds.
Play Mines Of Dalarnia
Conclusion
Chromia combines many groundbreaking features that purport it as a new generation blockchain and set it out among the crowd.
It's easy to code programming language, Postchain consortium, relational database system express qualities that fit different needs of decentralized applications and their operations. All of which state the chain strength and confidence of usage.
Under the governance of ChromaWay - an organization of tech experts and geeks. Chromia is expected to continue on an upward positive momentum.
Learn more about the project from it's official website
Their Telegram group chat is a good place to start interacting with the community.
Chromia has a Twitter presence and their Whitepaper is a good reference and tool to have a good overview of the project mission and vision at large.

Monero, the Most Private Cryptocurrency

Monero, the Most Private Cryptocurrency
Written by the CoinEx Institution, this series of jocular and easy to understand articles will show you everything you need to know about major cryptocurrencies, making you fully prepared before jumping into crypto!

https://preview.redd.it/ryvcznqspe451.jpg?width=720&format=pjpg&auto=webp&s=5fa91e26288d7b0a624113ed21172cc9fd5624a3
Monero, or XMR for short, is an open-source cryptocurrency that is safe, reliable, private, and untraceable. It can run on Windows, Mac, Linux, and FreeBSD, and is known as one of the most private cryptocurrencies. In 2018, Monero already ranked 10th in terms of trading volume, with its market value beyond 1 billion US dollars, an evidence for its great fame in this field.
By a special method in cryptography, Monero ensures that all transactions remain 100% irrelevant and untraceable. Perhaps after reading this article, you will understand why it is so special and popular in the increasingly transparent and traceable cryptocurrency circle (After all privacy comes first!).
In fact, many large cryptocurrencies in the world are not anonymous. All transactions on Bitcoin and Ethereum are made public and traceable, which means that anyone can eavesdrop on transactions flowing into and out of the wallet. That has given rise to a new type of cryptocurrency called “privacy currency”! These “privacy currencies” hide encrypted transactions by adopting specific types of passwords. One typical example is Monero, one of the largest privacy cryptocurrencies in the world.
Monero was created on April 18, 2014 under the name BitMonero, literally the combination of Bit (Bitcoin) and Monero (the “coin” in Esperanto). In five days, the community decided to change its name to Monero.
Interestingly, Monero’s creators valued personal privacy and tried to behave in a low-key manner with pseudonyms instead of the real names. It is said that the Monero major contributor’s nickname is “thankful for today”, yet this guy has gradually disappeared from public view as Monero developed day by day.
Unlike many cryptocurrencies derived from BTC, Monero is based on the CryptoNote protocol. It is also the first branch based on the Bytecoin of CryptoNote currency. Here is some information about Bytecoin: BCN, for short, is a decentralized cryptocurrency with a high degree of privacy; it has open-source codes that allow everyone to contribute to the development of the Bytecoin network; and the Bytecoin network provides global users with instant private transactions that are not traceable and at no additional cost.
Yet, as a branch of BCN, Monero outshines its parent in reputation by being different in two ways. First, Monero’s target block time was reduced from 120 seconds to 60 seconds; second, the issuance speed was cut by 50% (which reverted to 120-second residence later, with the issuance time maintained and the reward for each new block doubled). By the way, during the fork, the Monero developers also found a lot of low-quality codes and then refactored them. (That is exactly what geeks will do)
Monero’s modular code structure was also highly appreciated by Wladimir J. van der Laan, one of the core maintainers of Bitcoin.
Monero values privacy, decentralization and scalability, and there are significant algorithm differences in blockchain fuzzification, which sets it apart from its peers. How private is it? Here are more details.
1. Safe and reliable
For a decentralized cryptocurrency, decentralization means that its network is operated by users; transactions are confirmed by decentralized consensus and then recorded on the blockchain irrevocably. Monero needs no third party to guarantee the safety of funds;
2. Privacy protection
Monero confuses all transaction sources, amounts, and recipients through ring signatures, ring confidential transactions, and invisible addresses. Apart from all the advantages of a decentralized cryptocurrency, it is by no means inferior in safeguarding privacy;
3. Unable to track
The sender, the receiver and the transaction amount of all Monero transactions must be anonymous by default. The information on the Monero Blockchain cannot be matched with physical individuals or specific users, so there is no trace to track;
4. Scalable
Everyone knows that Bitcoin’sability to process transactions has always been limited by the scalability issue; as we have mentioned before in the introduction of Bitcoin, the block size of 1MB makes things difficult. But Monero’s developers have created a system that allows the network to process more transactions when needed; what’s more, Monero does not have any “pre-set” restrictions on block size.
Of course, this also means that some malicious miners may block the system with large blocks. To prevent this from happening, Monero has worked out countermeasures: the block reward penalty of the system.
On October 18, 2018, Monero’s latest hard fork changed the consensus mechanism algorithm to CrypotoNight V8. In this hard fork, it introduced the BulletProff bulletproof protocol, which can also effectively reduce the transaction fee of miners without disclosing transactions
It is said that Monero will issue about 18.4 million XMR in around 8 years. Moreover, it eclipses its counterparts in distribution — with no pre-mining or pre-sale, all block rewards will be left to miners by means of the POW mechanism.
Here is the reward scheme of Monero in two stages:
  1. Acceleration: mine 18132000 XMR before May 2022;
  2. Deceleration: Deceleration starts right after 18132000 XMR are mined, and there will be a reward of 0.6XMR for each block mined afterwards. In this way, the overall supply will be kept on a small scale and decelerated.
Monero is also excellent in its development concept that is designed to be anti-ASIC from the very beginning. Here is a brief introduction to ASIC (Special Application Integrated Circuit).
Due to the specificity of ASICs, specially designed ASICs can usually have much higher hashrate than general CPUs, GPUs, and even FPGAs — that makes hashrate excessively centralized and makes it vulnerable to the monopoly of single centralized institutions. Yet the cryptonight algorithm used by Monero allows most CPUs and even FPGAs to get involved and get mining rewards, instead of making GPU the only one that can efficiently mine.
In other words, Monero’s core development team will modify the consensus mechanism algorithm and have a hard fork after some time to ensure its strength against ASIC and the monopoly of hashrate.
However, although Monero has been designed against ASICs to avoid centralization, nearly 43% of its hashrate is still owned by 3 mining pools; in addition, it is not a BTC-based currency, making it even harder to introduce some elements. Of course, Monero is not that newbie-friendly, and thus has not been widely accepted.
Yet each cryptocurrency has its own features. As long as Monero keeps improving its privacy, it will definitely attract increasing followers. If you are interested in Monero, welcome to CoinEx for exchange or trade.

White Paper, Miner, Pizza … | "Old Objects" in the Cryptocurrency Museum

White Paper, Miner, Pizza … |
https://preview.redd.it/giu1ssilga151.jpg?width=900&format=pjpg&auto=webp&s=41510785ccdc0d99544ec74229f62427d1c0ce3e
Museum has played the role of a time recorder. Talking about bitcoin, more than ten years has passed since the creation of it. Although it is uncomparable to the stock market with a hundred years of history, during the ten years, in the different stages of the development of bitcoin and blockchain have continuously poured in geeks, miners, speculators, newbies, leaving keywords such as sudden rich, myth, scam, belief, revolution, etc.
There are also many “old objects” with stories in the “Museum” of the cryptocurrency realm. On Museum Day, let ’s review the stories brought by these “old objects”.
The First Digital Currency White Paper — Bitcoin White Paper
On Oct. 31, 2008, Satoshi Nakamoto released the Bitcoin white paper — A Peer-to-Peer Electronic Cash System in the cryptographic mail group where he belongs, and Bitcoin was born since then.
A white paper is a document that explains the purpose and technology used in cryptocurrency. Usually a cryptocurrency uses the white paper to help people understand what it provides, and it is also an important information channel for investors to understand a project. Therefore, the level of the white paper affects people’s confidence towards the coin.
In a word, in the cryptocurrency and blockchain industry, the value of a white paper is equivalent to that of a standard financing speech. The white paper plays a vital role in this emerging market.
The First Public Bitcoin-Physical Transaction — Pizza
Since Satoshi Nakamoto mined the Bitcoin genesis block on January 3, 2009, Bitcoin has only been spread among the small crowd and has not realized its value.
Not until May 22, 2010, Bitcoin enthusiast “Laszlo Hanyecz” bought a pizza coupon worth $25 with 10,000 bitcoins. This is the first public bitcoin-physical transaction. Bitcoin has its price with 0.3 cents per bitcoin.


This day has also become the famous “Bitcoin Pizza Day” in Bitcoin history. Bitcoin as the imagination of the financial system has more practical significance. The tenth anniversary is coming. How will you commemorate it? Will you buy a pizza?
The First Digital Asset Exchange — Bitcoinmarket.com
After the birth of Bitcoin, in addition to mining, the only way to get Bitcoin in the early days was to conduct transactions on forums or IRC (commonly known as Internet Relay Chat). However, this method involves both long transaction time and great security risk.
In March 2010, the first digital asset exchange — Bitcoinmarket.com launched. However, due to lack of liquidity and transaction depth, it disappeared soon after its establishment, but Bitcoinmarket.com opened the era of the operation of the cryptocurrency realm exchange 1.0.


On June 9, 2011, China’s first Bitcoin exchange — Bitcoin China (BTCChina) launched. Its founder, Yang Linke, translated Bitcoin into Chinese “比特币” for the first time. In 2013, China’s bitcoin trading entered the golden age, and exchanges sprung up. China monopolized more than 90% of the world’s bitcoin transactions. Now, if the top three exchanges Binance, Huobi Global, OKEx are the Exchange 2.0, then the index exchange represented by 58COIN called the 3.0 version, leading the trend.
The First Generation of High-Performance Miner — ASIC Miner
When Satoshi Nakamoto created Bitcoin, the only way to get it is to use computers (including home computers) to mine, mainly relying on the CPU to calculate. However, as the value of digital currencies such as Bitcoin has become higher and higher, mining has become an industry with the competition is getting fiercer, accompanied by increasing difficulty of mining. Therefore, hardware performance competition starts.
In July 2012, the genius Jiang Xinyu (Internet nickname is “Friedcat”) from the junior class of the University of Science and Technology declared at the forum that he could make ASIC miners (chips). As far as mining computing power is concerned, ASICs can be tens of thousands or more higher than the same-generation CPUs and GPUs.
At the beginning of 2013, Zhang Nanqian (Pumpkin Zhang), a suspended doctoral student from the Beijing University of Aeronautics and Astronautics, developed the ASIC miner and named it “Avalon”.


In June 2013, the Friedcat’s miner USB was finally released, and it maintained 20% of the computing power of the entire network.
At the end of 2013, Wu Jihan, used the tens of millions yuan earned from Friedcat through investment, worked together with Jenke group, to develop the Antminer S1. Since then, the miner manufacturer Bitmain began to enter the stage of history.
It is no exaggeration to say that Friedcat and Zhang Nangeng have opened the domestic “mining” era.
The Birthplace of China’s Bitcoin — Garage Coffee
It is not only the “old objects” that record history, but also a place that everyone in the cryptocurrency realm aspires to.
Guo Hongcai once said, “Without no The Garage Café, there will be no cryptocurrency realm today. Since it is a very mysterious place that all waves of people from the café joint together to create today’s digital asset industry.

▲ In March 2013, American student Jake Smith successfully purchased a cup of coffee at The Garage Café with 0.131 bitcoins. This move attracted the attention of CCTV, and it conducted an interview.
Indeed, The Garage Café is the world ’s first entrepreneurial-themed coffee shop. It has been legendary since its establishment in 2011. The Garage Cafét is not only the core coordinate on China’s Bitcoin map, but also the birthplace of the Chinese cryptocurrency circle, where digital asset realm tycoons including Guo Hongcai, Zhao Dong, Li Xiaolai, Li Lin have made their ways.
The development of digital currency is only 11 years old. Through these “old objects”, we review the various stories of this wave of technology together, hoping to help you understand the development process of the digital currency field. Meanwhile, I also remind all practitioners to use history as a mirror and forge ahead.

How the Bitcoin price was changing

Nowadays, the Bitcoin currency rate perhaps is the most unpredictable thing. All predictions about how BTC price will increase or drop are in some way similar to the weather forecasts. No one can tell what will happen to the coin tomorrow. One of the most important factors that experts rely on is the history of the currency rate over the whole period of BTC existence with its dynamics. It is essential to know what was happening to the coin as this allows you to understand what can happen to it in the future.

2009

The first digital currency – Bitcoin – came to the world on January 9, 2009. In the same month, the creator of Bitcoin mined the first block and he also made the first financial operation in the BTC system.

At the beginning of its history, the Bitcoin price was ridiculously low. The first exchange of BTC to US dollars was made in the summer of 2009 when Martti Malmi received 5.02 USD for his 5050 Bitcoins.

The first official Bitcoin exchange rate to the fiat dollar was established on October 9, 2009. At that time, for 1 dollar you could buy 1 309.03 BTC. Many people now regret that they missed the opportunity to buy Bitcoin for pennies.

2010

In 2010, events in the cryptocurrency market began to develop more intensively. The Bitcoin Market exchange was opened in February 2010, where it was possible to sell the digital coin. In May of this year, the most well-known deal with Bitcoin had happened. The programmer Laszlo Hanyecz bought 2 pizzas for 10,000 BTC. It was the first purchase using cryptocurrency in the real world. He posted a request on the crypto forum saying that he wanted to buy two pizzas. In exchange for that, he offered 10K Bitcoins that back then cost about 40 dollars. And there was a person who agreed to have this deal – it was the 19 years old Jeremy Sturdivant. Jeremy didn’t become a millionaire since then as he spent his coins to travel across the USA.

As for Laszlo, he doesn’t regret about the lost millions. He was mining coins for his pleasure at that time and spent them to different non-significant things.

In July of 2010, BTC price raised to 0.08 dollars. Then in November, the price went up for 50 percent. In general, 2010 was an excellent period for strengthening the position of Bitcoin. The digital currency was almost able to reach the point of one dollar.

2011

BTC overcame the point of 1 dollar only in February of 2011. By early June, the price had grown to 10 dollars. This was a small victory for Bitcoin. Another maximum was set at the point of $31.91. In the middle of June 2011, there was a sharp drop in price: from 31.91 again to 10 dollars.

The year 2011 was full of negative events. One of them happened on June 13, when a user’s electronic wallet was first hacked and 25 thousand coins were stolen from there. In a few days, some geeks hacked MtFox exchange where they got data of sixty thousand users. These events negatively affected the Bitcoin rate. It became clear that in the future the price of digital currency will be determined taking into consideration any events that occur in the market.

2012

In 2012, the exchange rate was ranging from 8 to 12 dollars per 1 BTC. This period was also rich in significant events. One of them is that Bitcoin Central bank began its work. This bank received a license and was even recognised by European regulators.

2013

February 22, 2013, was the day when Bitcoin began to grow again. The price reached the mark of $30. Another increase occurred at the end of January – $31.9. The upward trend continued. March 22 rate was 74.9 dollars per BTC.

On the first day of April, the price went up to $100 and within another nine days, the BTC price grew to 266 dollars. But the growth did not last long. By October it was $109. The possible reason for that is the arrest of an anonymous trading platform Silk Road.

Since November 2013, the price of Bitcoin began to grow anew. By the end of the month, the price exceeded all expectations and raised up to $1,200 per coin. The reason for overcoming the $1,000 point was the BTC support by Zynga game creator. Experts also noted another event that could affect the growth: one of the higher education institutions in Cyprus started accepting the Bitcoin as payment for tuition.

But by the end of the first week of December, the price was 1,000 dollars. In the middle of December 2013, the BTC price dropped to 600 dollars because the China Central Bank prohibited the country’s financial institutions to maintain operations with cryptocurrency.

2014

During the year 2014, there happened rather a significant amount of events that had an impact on the Bitcoin volatility. In the first days of January, 1 BTC was equal to 770 dollars. In February it was 700 dollars. Summer 2014 slightly strengthened the reputation of the cryptocurrency.

Many experts think that it was 2014 when BTC strengthened its position in the market, in spite of the fact that Bitcoin price was low – by the end of the year it settled in at around 310 dollars. In 2014 investors began to consider Bitcoin as a potential investment as Bitcoin price predictions seemed quite attractive.

2015

At the beginning of 2015, the BTC price started rising: with 177 dollars in January to 281 dollars to March. The number of people who were trading Bitcoin increased – there were about 160,000 people was buying and selling BTC on exchanges by August 2015. In one period of 2015 the Bitcoin price grew up to 500 dollars, but to the end of 2015, it dropped to about 350 USD.

2016

In 2016, Japan declared Bitcoin as a currency and allowed to use it to pay for goods and services. South Africa was the next who did the same. In April 2016, BTC rate went up and reached $454 per coin. By the end of May, 1 BTC was already worth $600. The reason for the price increase might be the growth of the number of transactions in the Chinese market. The highest price in 2016 was in December – $950 for one Bitcoin.

2017

The year of 2017 was an incredible period in respect of BTC price. It started with $1,000 for 1 coin. Already in June, it was $2,600. By the beginning of September, the price jumped to $5,000 per 1 BTC. On December 17, the Bitcoin price achieved a record and was over 20,000 US dollars.

How did this happen? Here are some reasons that experts point due to the growth of Bitcoin price:


However, later in December, the price plummeted from 20 000 dollars to 12 000 dollars. Experts had different reasons including that one of the first cryptocurrency creators sold out all his digital savings and called such investments too risky.

2018

During the first 4 months of 2018, the price of BTC dropped below 7,000 USD. These negative dynamics were quite logical because the rise is always followed by the fall. For the first time since October 2017, the Bitcoin price fell below 6,000 dollars. On November 25, the price of Bitcoin fell even lower – $3,676 per 1 BTC. By mid-December, the bitcoin rate fell by almost 80% to its yearly rate, the price was $3,200.

Nowadays

What can we expect in 2019? What Bitcoin price predictions do crypto experts have? People hope that 2019 will bring new opportunities for Bitcoin and also other cryptocurrencies. Some investors and crypto enthusiasts predict that the BTC price will grow to 40 – 50,000 USD by the end of 2019. One of them, John McAfee, is assured that the price will rise to 1 million dollars by the end of 2020. He even had a bet that he posted in his Twitter saying that he would eat his “love muscle” if his BTC price prediction will not come true.

There may be a number of factors that can influence the BTC price in 2019. They are:

As it was said before, Bitcoin price predictions are almost like the weather forecast – you never know what price it will have tomorrow. If you think about investing in BTC or any other cryptocurrency you should follow its rate at present time but never forget to compare it to the past. But please, don’t bet to eat any of your body parts 🙂

some days I hate existing (life situation vent)

sorry if this is a downer post, but I literally had to find and join this sub-reddit just to be able to get some shit off my chest from today and life as a whole right at the moment... thank you for having this Reddit exist, first and foremost, because life sucks for me lately, in general, and for a good number of years, and I am having one hell of a bad day and just need to get this shit off my chest before I have a meltdown. so thank you for whomever created this sub-reddit.

anywho... hey, how's it going, my name is Mike IRL, but I just go by the name High Voltage online, I am a furry, and to use a short and to the point name everyone calls me anymore, I'm just gonna say Hey, I'm volt.

anyways... I'm an autistic furry, I love life...usually...but as of these last handful of years, life has just been one hell of a suck fest. I am a computer geek, self taught, by nature, passion, and habit, I love technology, but the more I learn, the more I realize Murphy is a vindictive bitch. Murphy in this case is Murphy's law, and me and that little shithead have a love hate relationship... I love technology, he loves to make technology hate my guts, and the more I learn about shit, the more I can tell just how much shit goes wrong in ways that are uncommon for me, and for general life. I have friends in the tech industry, that all unanimously agree, and I quote them all here "how the FUCK do you have so many things go wrong?!" this includes a friend who works for dell as a storage expert, a friend that's a tech support call center representative, and a plethora more friends that are just over all tech heads. one point I need to get off my chest.

another thing, is that for the life of me, for the last 10 years since graduation from high school, nothing I do is allowing me to get my ass in a tech job, no amount of experience personally taught, no amount of tech certifications make any difference, nothings helping and I've had to jump from one dead end job to another, just to be able to even afford to survive, and hell, that's a joke in and of itself, cause I cant even afford to be alive, and live, I am barely scraping by, ever, and am forced to live with my parents because I cant even afford subsidized housing, section 8 or otherwise.

per my autism and other issues, I have to take prescriptions just to function in society, which on their own, cost more than I have ever made in a month at any job I've ever had to date, given they are around 8k a month without insurance.

on the comment of insurance, I have to use medicaid/medicare just to be able to afford to be alive, which in turn makes me have an income limit per month, so I cant ever make more than about 1 thousand dollars in a month, making my whopping glorious yearly income, four thousand dollars a year less than poverty, which is classified here in my state as 16 thousand dollars a year.

usually this does not bother me and I'm able to maintain a fairly positive outlook on life, plus or minus my usual depression...and I don't usually let things bug me, and have made in my opinion, a name for myself as being generous, and donating money whenever I'm able to to those less fortunate than myself, countless times I've helped keep friends of mine online whom I have never actually met, and hold credible for being in the situations they claim to be at face value because I trust people and I'm a compassionate person... I have been told so many times by my parents that I'm too trusting, that I have literally lost count...

I have even been scolded by my father once for, and I quote, "your not an entrepreneur, strive for mediocrity!" while a friend of mine was at my house in the basement waiting on me, when my father found out, while I still had my income cap, BEFORE government regulations happened, regulating bitcoin as a taxable asset (I have since gotten out of the bitcoin game for a few years now and it served its purpose while it lasted)

but all of these things are normally manageable on their own in stride.... the thing that's finally just caused me to have enough at this point is the fact that I just realized how truly shitty my current discovery is right now....

more on that one in a moment however...

the one thing that I have always been proud of is this, the fact that I am self taught for all of my computer experience that I have amassed to date, including but not limited to having to be resourceful on finding good deals, given that I found and paid for myself on my measly income, all of the servers that I have to date at my ownership, all found through scrounging for deals, on Facebook marketplace, and driving literally half the entire state of Ohio one way trip to find a deal for a thing I'm after, I have HAD to be resourceful for everything, because I had nothing for income... this includes having to plan and build my own data server using second hand parts, whenever possible, and I have not had any regrets on that, because it has allowed me to get still working systems for damn good prices... so I have never, until today, regretted that... because it has always been mine, built with pride, pride that I found good deals on things, that still worked, and still had usefulness to someone (me) and gave these devices a second lease on life, for good prices, and it was something I did myself, through sheer determination, patience (something I severely lack, and the entire reason I fish for catfish when me and my folks go fishing), and resourcefulness.

welp....honestly, at this point, I don't know what the hell to do now, because out of all of the drives that I have tested so far that this thing uses, after having lost unimaginable quantities of priceless memories that I can never get back, thousands and thousands of dollars in software I cant get back (one of many failures of the storage server, and mistakenly purged gmail emails, leaving zero traces of the software and no ability to discover what it was to try and recover it anymore) and numerous personal memories in the ways of family photos lost among so much more...

of all the drives in this system, over half of them now are saying they are IMMINENT failure, and all of them, every single one of them, is either pre-fail or old age, and given that I have always HAD to buy second hand used and abused storage off of ebay, its no surprise that this has become the case.....normally I'd say "oh well, sucks, gonna have to save up and buy new drive replacements again" in the form of more used drives.....but now, the icing on the cake here, and why I'm at my point of typing up this entire post? I am one of the people that lost their jobs due to this whole pandemic....so....I literally have no way what so ever, to even try and replace these drives...and now I am left with an empty feeling in the pit of my stomach, and an epic oncoming depression fit.

bonus fun points to the fact that I do my damnedest to never ask for funding help for anything in my life ever, given that its the mindset of "my projects, my fun times, my money, nobody else should /HAVE/ to help me given this is MY fun stuff" and the few times I ever ask anyone for help, everyone always jumps down my throat, friends wise, saying how greedy I am as a person to ever ask for funding help for MY stuff, and "what will I get out of it? nothing? then why the fuck should I want to help YOU if I don't get anything from it?" so I always tend to not WANT to ask for help, EVER, given this is how I get treated when I do, and then the few times that I genuinely feel like I need to, after always having that mindset of being a burden to the world, and a nuisance to my friends, when I finally get up the nerve to fucking do so and make a gofundme out of sheer necessity...out of all of the times I have done so, over the years, I literally can count on one single hand, the number of times anybody has ACTUALLY helped me....and I get it, it does not effect them at all, and its their money, trust me I get it, but when I DO actually need help, I never get it... this is one of those times I need help...and I wont get it, and I truly understand that, especially now with this pandemic and so many people being out of their jobs and or scared of losing their jobs, I understand that, I wouldn't be able to now even if I wanted to anyways, but it just fucking sucks... always going so far out of my way to help others when I'm able to, and then life always being such a fucking bitch like this to me.

*sighs heavily* anyways....sorry for the vent, but I fucking needed to bitch and moan somewhat today...god knows I've been forced to try and bottle it up for far too fucking long, because everyone's been tired of my bitching, even though I tend to only do so, to enough of a degree to keep my head afloat as needed.

just for shits and giggles, I'll post a link to the hard drive reports, just to share what I am forced to work with because its all I can afford...not that I have any problems with it mind you, if it works, and I can afford it, then that's what I'll take any fucking day of the week, given its a means to an end.
https://drive.google.com/drive/folders/1gK7EGCU9fX9lcC1G4to2ZwbvNA8cBVQM?usp=sharing
anyways...as usual, I've made my gofundme, and as usual, I know what to expect...nothing...but whatever. such is life.

Introduction to Cryptocurrency: BTC, the King of All Tokens

Introduction to Cryptocurrency: BTC, the King of All Tokens
Written by the CoinEx Institution, this series of jocular and easy to understand articles will show you everything you need to know about major cryptocurrencies, making you fully prepared before jumping into crypto!
https://preview.redd.it/d6qqcqnqpsn41.png?width=1638&format=png&auto=webp&s=3e1873bd9f22e159fe5675e1e7314a75eaf61ad4
If you are not in the cryptocurrency field, “BTC” may be a stranger to you, but not the Bitcoin. BTC is the abbreviation for Bitcoin. In addition, it has another name: XBT.
Speaking of BTC, we have to mention one name, Satoshi Nakamoto, father of BTC. His story started from 2008 when a financial crisis broke out across the world, which laid a foundation for the birth of BTC.
On November 1 that year, a person claiming to be Satoshi Nakamoto published the BTC White Paper titled “BTC: A Peer-to-Peer Electronic Cash System” on a P2P foundation website, marking the birth of BTC. Two months later, on January 3, 2009, the BTC genesis block was created. BTC got rid of the constraints of third-party institutions by distributed ledgers, which Nakamoto called the “blockchain.” If users are prepared to dedicate their CPU hashrate to run a special software, they can become a “miner”. While mining new BTC, the miners also set up a network to maintain the blockchain together.
At the time, BTC was considered as a virtual commodity, not a currency, by some countries, banks and government agencies. It wasn’t until one day a man bought two pizzas for the 10,000 BTC he had mined that BTC had its value (What a losing business).
After that, there are ups and downs of the BTC market, but the identity of Nakamoto, has always remained a mystery. Some say he’s from the National Security Agency, and some say he’s a financial expert. But still, he is nowhere to find, and nobody knows anything about him.
The wonderful part of BTC lies in the fact that it is something anyone can mine! But if you think you can mine as many BTC as you want, think twice. To avoid inflation, the upper limit for the number of BTC was set at 21 million. Without relying on the central authority, BTC is issued by the blockchain. Assets and transactions are secured by the digital encryption algorithms and the entire network to resist 51% hashrate attacks. Transaction records are collected and maintained by all computers on the network, and the validity of each transaction must be confirmed by blockchain inspection.
People say, having been widely recognized and used, the BTC technology presents all mankind with an era of blockchain. As the king of cryptocurrency, what makes BTC so special?
1. Decentralization
BTC is the first distributed cryptocurrency. The entire network consists of users and there is no central bank. Decentralization guarantees the security and freedom of BTC.
2.Worldwide circulation
BTC can be managed on any computer connected to the Internet. No matter where you are, you can mine, buy, sell or receive it. That is exactly what makes it a magnet for a lot of miners and users.
3. Exclusive ownership
Controlling your BTC requires your private key, which can be isolated and stored on any storage medium, and no one can get it except yourself. That experience makes you feel so special and secured.
4.Low transaction fees and no hidden costs
The BTC network will charge a certain fee for each transaction to ensure faster transaction execution. In addition, as an A-to-B payment method, BTC does not have tedious procedures or limits, and users only need to provide a BTC address to make payment. How convenient!
5. Cross-platform mining
Bitcoin is definitely a passion for geeks! Miners can discover the hashrate of different hardware on many platforms. BTC mining can be both profitable and fun.
Today the circulating market value of BTC has reached 1.32 trillion, and the reward is halved about every 4 years. In May 2020 we will usher in the third halving of Bitcoin, with a block height of 630,000, and the reward will be directly reduced from 12.5 BTC to 6.25 BTC. By 2140, there will be no more new Bitcoin generated in the world, and the number of Bitcoin in circulation will not exceed 21 million.
If you want to enter the cryptocurrency field, you might as well start by buying BTC. It may present a new door to wealth in front of you, and the key to this door lies in CoinEx. Come on, learn more and trade! https://www.coinex.com/
