For example the introduction of coins bit block chain:
- ① For example, today Panhu find Nobita borrowed $ 100, then I can help do the accounts as a middleman record: 2020.01.01 Panhu find a large borrowed $ 100, but my books could be lost, may be said to cook the books.
how to solve this problem?
- ② We decided to all my friends to help accounting. Even twelve loss has no effect, so Gian can not deny.
这就是去中心化分布式数据库。（区块链）
Why we will help billing it?
- ③ because we have decided to reward the first billing fastest and most accurate accounting of a personal
比特币(Bitcoin)
Added: how to ensure the accuracy of the accounting of it?
- We will give a mathematical problem in accounting money. The fastest people can find particular solution of this problem we'll give him Bitcoin, the rest of the people will refer to its record books, will be updated once every ten minutes.
Distributed accounting books refers to the transaction completed by the plurality of nodes located in different places together, and each node is a complete record of accounts, so they can participate in the supervision of the legality of the transaction, but can also testify to their common
1. What is the Block Chaining (Blockchain)
- concept:
区块链是一种去中心化的分布式账本数据库。 - purpose:
用于验证其信息的有效性（防伪）
Bitcoin block chain originated in 2008 November 1, a self-proclaimed Satoshi (Satoshi Nakamoto) who published "Bitcoin: a peer to peer electronic cash system," a text, elaborated based on P2P network technology, architecture concept electronic cash system of encryption technology, the time stamp technology, block chain technology, etc., which marks the birth of Bitcoin. Two months later theory into the practice, January 3, 2009 for the creation of a number of 0 blocks birth. A few days after January 9, 2009 appears to block No. 1, and the serial number creation block 0 are connected to form a chain, marking the birth of the block chain.

To the center : Block chain technology does not rely on additional third-party management or hardware, there is no central control, in addition to self-contained block chain itself, through distributed storage and accounting, information on each node to achieve a self-validation, transfer and management. To the center is the most prominent feature of most essential block chain
-
Openness : block chain technology is based on open source, in addition to private information outside of the parties to the transaction is encrypted data block chain is open to everyone, anyone can through open interfaces and data query block chain and develop its application , so the whole system is highly transparent information
-
独立性：基于协商一致的规范和协议(类似比特币采用的哈希算法等各种数学算法)，整个区块链系统不依赖其他第三方，所有节点能够在系统内自动安全地验证、交换数据，不需要任何人为的干预。
-
安全性：只要不能掌控全部数据节点的51%，就无法肆意操控修改网络数据，这使区块链本身变得相对安全，避免了主观人为的数据变更 。
-
匿名性：除非有法律规范要求，单从技术上来讲，各区块节点的身份信息不需要公开或验证，信息传递可以匿名进行。
- 区块链是如何去中心化的呢？
- 区块链可以理解为是一个去中心化的分布式数据库。这个数据库不依赖任何机构和管理员，区块链的作用就是存储信息，数据库的数据由全网的节点共同维护，任何人都可以接入区块链网络，成为一个数据节点。如果向数据节点写入数据，这个节点会将写入的数据信息广播到相邻的节点，然后相邻的节点再广播到它们相邻的节点，最终会将信息广播给全网的所有节点，最后所有的节点会同步数据，保证一致性。
二.什么是比特币（Bitcoin）
- 概念：比特币是一种P2P形式的数字货币。
补充： P2P（即点对点）的传输意味着一个去中心化的支付系统。
- 比特币的诞生
比特币的概念，最初由一个名为中本聪的大神在2008年11月1日提出。2009年1月3日，中本聪在位于芬兰赫尔辛基的一个小型服务器上，亲手创建了第一个区块——比特币的创世区块，并“挖”得了比特币系统中的第一笔50枚比特币。
- 特征
比特币与其他虚拟货币最大的不同是：其总数量有限，只有2100万个，目前已经被挖出了约1500万个，预计2140年所有的比特币会被挖完。
三.区块链比特币小结
The gifts you have are not a reason to be proud, because they were given to you in advance, and you can be grateful for them, but the choices you make, the choices you make to work hard, the choices you make to do very difficult things, that’s the choices you make to be proud of.
