Blockchain is actually two words, block and chain. Every bill is an obstacle. When linked, it is a blockchain.

First of all, at the beginning of the operation of Bitcoin, Xiaoming 200 yuan was given, stipulating that whoever enters the account first will get 10 yuan (this is a * * * knowledge mechanism to encourage everyone to agree to do the same thing), and then a lot of blank bills were given to everyone. Once a transaction happens, everyone can compete for bookkeeping.

1 One day, Xiao Ming gave Li Si 100 yuan (this is a deal), and then Xiao Mingcan shouted in the crowd, I also want to give Li Si 100 yuan (and sign my name). You can compete for bookkeeping as soon as you listen.

Because Wang Wu remembered quickly and was the first to finish, Wang Wu gave a cry in the group. I remember it very clearly. This is Wang Wu. Give the bill to someone else. Wang Wu remembered clearly that everyone confirmed that there was nothing wrong (signed by Li Si), so Wang Wu won the award of 10 yuan, and then everyone put the bill on the last page of their books. & lt There can be multiple transactions in one bookkeeping & gt；;

Wang Wu likes playing the glory of the king very much. He has always liked a hero, De Mathea, but he needs 25 yuan, while Wang Wu only has 10 yuan, which is obviously not enough. Wang Wu began to think about my own bookkeeping. Anyway, I can't see anything from the ledger. Soon Wang Wu got the opportunity to keep accounts. In addition to keeping other accounts safe, Wang Wu added one, and Wang Wu gave it to Tencent 25, and then announced it in the group.

4. While Wang Wu was happily waiting to receive Demacia, Li Si carefully looked at the bills, all of which were signed by himself, and there was no problem. However, Li Si turned over the previous bill and found that Wang Wu only charged 10 yuan, so she refused. Again, everyone refused.

Wang Wu's plan failed, at the cost of wasting a lot of energy but not being rewarded.

The above basically explains the process of regional chain,
