2015 "Internet +" attracted national attention, and now the "block chain +" from concept into reality.
+ Payment block chain, block chain + credit, + energy block chain, block chain + Insurance ...... block chain technology is constantly ignite people's passion, whether traditional institutions or new companies, have chosen to catch up, spend layout.
In fact, most began to understand that because bitcoin block chain is that what Bitcoin is, what is it blocks chain?
We look at a story Landlords:
Business man, grandfather and boy together Landlords, landlords amazing win 10 dollars, farmers have to win five dollars per person. To avoid deadbeat, they agreed to come up with 100 dollars per person, there is Santa Claus, Santa Claus is responsible for bookkeeping. Accounting following table:
Santa Claus is the center of all of them trust each kick regarded brand competition results tell Santa Claus, Santa Claus is responsible for bookkeeping.
For example, as the landlord business men won the first game, and that is the next books:
Three people can have fun playing cards, bookkeeping things to Santa Claus. But this center accounting, there are some problems:
1. Santa Claus elderly has been high, and if suddenly hung up how to do?
2. The village has a hacker appeared, put the money in Santa Claus stole how to do?
3. Santa Claus hike, requires each accounting charge for all how to do?
4. Santa Claus embezzlement, put out 300 dollars to lend again, not recover in time how to do?
5. Santa Claus record everyone's private data, he sold these private information how to do?
6. Santa Claus opened a large Internet casino, while record 10,000 people Landlords, too busy to how to do?
In fact, the above are some of the risks of trading centers, in order to solve this problem, a new decentralized accounting techniques, and this is Bitcoin. He is Japanese Nakamoto invention.
Decentralized as follows:
Santa accounting no longer rely on one person, there are countless individuals can participate in the system accounting, billing people involved in the system and will give a little reward, so called mining accounting, billing people called miners.
商务男，小朋友，老爷爷打完牌后，把比赛完毕后的转账记录， 以大喇叭广播的方式告知所有的记账的群众(矿工)， 第一个脑子灵活，运气好，算账快的人就得到了记账权，他记好账后就以大喇叭广播的方式， 告诉其他的矿工，看我的账本写好了，你们直接抄我的账就行了。
这个账本同步存储在每个群众的账本里面。 分布式记账系统解决了中心记账的问题。
关于里面的技术细节,我们后面会一一介绍。用代码的方式带大家实现。
中心化和区中心化用一个图可以容易的理解：
以上结论：
• 比特币不是一种货币, 他是一个分布式的总账系统, 电子总账在每个参与者电脑上备份, 实时的同步和对账；
• 总账记录这一定数量的比特币从一个参与者到另外一个参与者的过程, 每次记录都会广播到网络；
• 比特币本身没有价值. 比特币的价值在于, 第一个通过去中心化的分布式信任系统实现了价值转移；
