Open source spirit bitcoin
The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar
< H2 > extended information:bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin
I think it is certain to give up
17 years to participate in a dinner, drink half of the wine. People in the group let me share what bitcoin is. Then a big man said: & lt; It's Nakamoto that invented bitcoin, right? How many bitcoins does he have? The first bitcoin system can only run on its own computer, so it is paid for the previous block, which is estimated to be about one million
big brother also said that this is too little, a total of 21 million. As the founder and chairman of the board, Sun Tzu should have at least 67% of the shares and absolute control, or worse, 51%. Moreover, he will separate every transaction in the future
I don't think the boss is going to stop. Pull the boss to say drink. Who knows, Nakamoto is an idiot. Mom, I think I just told another interesting story. Yes, the maximum amount of a bitcoin is more than 100000. If you think of bitcoin as a company, its market value is more than 2 trillion, ranking among the top ten in the world. If Nakamoto had given himself more marks, he would now be the first rich man in the world. Both Bezos and Bill Gates have to call dad{ RRRRR}
Yes, human beings are selfish. The world is the jungle. There are common genes in human DNA. That makes us feel the same emotions. It's one of the guarantees that we humans can help each other and live to the present
the highest price is 1 million bitcoin, worth 20 billion US dollars. Since the birth of bitcoin in 2009, there has been no bitcoin in Nakamoto's wallet address
every time I think about this, considering the struggle against humanity and ugliness, I think life is worth it. If we calm down, we can win
Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below
The inventor of
bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system In 2010, he graally faded out and handed over the project to other members of the bitcoin communityNakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is
bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin
Bitcoin is an Internet virtual asset
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions
and use the design of cryptography to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
the design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
extended data:
currency features:
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform Mining: users can explore the computing power of different hardware on many platforms
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items< On February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
briefly describe my understanding: the project leader needs to build a bithub application on heroku, which manages the bitcoin donation fund of open source software users for a GitHub project (the donation address needs to be disclosed to the public). Whenever there is a commitment code (including the accepted pull request code) of a GitHub project specified by a developer, The bithub application on heroku will send bitcoin of a certain proportion of the fund's remaining total amount (as if it is% 2 by default) to the committer to reward his contribution
it will bring two effects to its GitHub project:
the publicity effect of bitcoin as a gimmick. There are still quite a few developers who don't know bitcoin or disagree with it, which will increase the attention of the project in today's social platform
the software fund promotes an atmosphere of "offering a reward". When developers know that they will get a reward for contributing code to a project, they will rush for it, especially when they see the attractive number lying there. The activity of the project is rising. Of course, quality is another thing
in fact, it's simple enough. It's just a bot that automatically manages the donation fund of software. Bitcoin is not its core, but it is also difficult to leave bitcoin. If bitcoin, which is inconvenient to pay and exchange, is changed into legal currency, this kind of project will be suitable for more situations and will be welcomed by more developers. However, legal money needs to be connected with payment instruments or payment platforms. Obviously, there is no cheap and easy to implement solution in this respect. So ultimately, it benefits from the decentralization of bitcoin. Everyone can freely control their own account, so that all kinds of payment based applications can enter the market at a lower threshold
the disadvantages of bithub are also obvious, and the first one is quality control. Bithub's paper per commit model only takes the number of code updates submitted as the quantitative standard, and ignores the content and code quality. Maybe after using bithub, code review will make people feel tired. The second drawback is fairness, which is related to the fact that the quantity is not guaranteed and the quality is not guaranteed. If a committer submits a critical update, which greatly improves the performance and quality of the software, but the software fund pool is very small at that time, then the committer can only get relatively few rewards. After that, the improved software will bring users a better experience, and then users will give higher donations, so the fund pool will rise, but the benefit of this rise will be the people who commit code in the future. In my impression, one thing about the spirit of open source is that whoever contributes benefits. Originally, the biggest beneficiary should be the initiator of the project. Although the biggest beneficiary is the initiator, there is nothing wrong with it, but 98% of users' donations are in their own accounts. Will other defenders lose their trust? No one can supervise the project holders on the other end of the Internet, who only spend the project funds on software maintenance
at the beginning, I just read the first title of the blog and thought it was open source software customization in crowdfunding mode (think about the Apache foundation in crowdfunding mode). In fact, the current software foundation is not far from the form of fund-raising customization. If enterprises want to continue to benefit from an open source project, they need to donate funds to make it active (such as Google and eclipse). This is no more than the difference between paying first and paying later. In essence, the difference is not too big
finally, let's talk about the personal solution to fairness:
the simplest way is to cancel the fund pool, change the paper per commit to donate to commit, users or other developers directly donate to the designated commit, and the value of commit is determined by users and other developers. At the same time, it solves the problem that the quantity is not guaranteed and the quality is not guaranteed
or change the settlement method, and each donation will be equally distributed to all submitted commits. But this method still can't guarantee the quality, unless we introce the evaluation system for commit like the previous suggestion
in the final analysis, bitcoin is still indispensable to these modified schemes. Except bitcoin, there is no cheap solution that can manage assets automatically and conveniently.
