Get bitcoin from GitHub

1. Open source software, see: https://github.com/bitcoin/bitcoin/

2. And this: https://github.com/bitcoin/bitcoin

4. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, 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
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency 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. 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
hope to adopt

5. Because the total amount of chain gram distribution is limited,
and the output is halved every 366 days, it will be more and more difficult to obtain chain gram as time goes on. So act early~~

6. At present, ripple official website is engaged in activities. GitHub account meeting certain conditions can receive 2020 ripple coins (a virtual currency like bitcoin), which can be converted into about 78 RMB according to the current exchange rate (which can be directly discounted on ripplecn and ripplechina). Therefore, don't be cheated to return money for the number of people, exchange it for fun by yourself

P.S. the requirements of GitHub account for receiving ripple currency are as follows:
we're giving away 2020 XRP (as a contribution to tomorrow's ripple developer conference at money 2020) to GitHub account holders who have at least one public code writing activity before May 1, 2013, 00:00:00 UTC.
official announcement: https://ripple.com/blog/git-in-the-game-2020-xrp-giveaway-for-github-users/

I believe that people who have GitHub accounts and are eligible to receive them should easily find a way to receive them

7. I think the core of this kind of project is not bitcoin, but the allocation and operation of software fund
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.

8. According to the regulations, according to the current deed tax policy, indivial purchase of housing implement differential tax rate. When an indivial purchases an ordinary house, and the house is the only house of the family, and the area of the purchased ordinary commercial house is less than 90 square meters, the deed tax shall be 1%; If the area of a house is between 90 square meters and 144 square meters, the tax rate will be halved, that is, the effective tax rate will be 2%; If the area of the house type purchased is more than 144 square meters, the deed tax rate shall be 4%. The purchase of non ordinary housing, two or more sets of housing, and commercial investment properties are taxed at the rate of 4%.
