This article is based on the Geth client mentioned earlier in this article, explaining how to build your own private chain, as well as account management and transfer transactions.
1. The Genesis block file
The first chunk on the blockchain is called the Genesis block, and the creation of our private chain can be declared and defined by the creation block config
" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp" : "0x00"
}
Step 2: Execute commands to create a Genesis blockSwitch back to the command line, execute the command, create the creation block into the Geths directory, execute the command geth--datadir "./" Init Genesis.json the current geths directory will now add two folders Geth and KeyStore Geth the data stored in the blockchain is the keystore of the user inf

Once created, in atom, there should be only one Genesis.json under this folder
Step 2: Execute commands to create a Genesis block
Switch back to command line, execute command, create Genesis block

Hash algorithm
Defined
Hash (hash or hashing) algorithms are very basic and very important technologies in the field of information technology. It can map any length of binary value (plaintext) to a shorter fixed-length binary value (hash value), and different plaintext is difficult to map to the same hash value.
For example, the MD5 hash value for a paragraph "Hello
