Blockchain is one of the current technology hotspots, some people compare it with the internet, and some people claim that the blockchain has no future. There are companies and individuals who have tried to apply it to other areas of the world, when most people's understanding of the blockchain still rests on the concept of cryptocurrency and other cryptographic digital currencies. To make a reasonable assessment of a thing, a more in-depth understanding is essential, and the faster way to learn
Bitcoin is decentralized to prevent unauthorized currency sending by currency issuing institutions.
The main reason for currency depreciation is that currency issuance institutions in various countries are sending out of stock, and the currency that has been sending out of stock is equivalent to tax collection from the currency holder, resulting in a reduction in the value of the currency.
To reform the status quo and give full play to the greater eff

This article will briefly introduce the block chain (blockchain) and use Python to do a simple implementation. What is a block chain
In a nutshell, a block chain is a permanent, irreversible modification of a record of encrypted data (chunks) stacked (chained) in chronological order. Specifically, the block chain is made up of a string of data blocks that are generated by a cryptographic method, each containing a hash of the previous block, starting with the Genesis block to connect to the curre
This article I use Python to implement a local block, to achieve a complete block chain also need to do a distributed server, a lot of things. First, the transactions are stored in chronological order, and the transaction of the bits and other encrypted currencies that are traded using the block chain are saved in time and are publicly stored. In layman's parlance, a block chain is a public database in which new data is stored in a container called a block and added to an immutable chain (hence

In particular, hashing algori
