This is a concise summary of the given text: A blockchain is a simple structure composed of blocks connected together like a chain. Each block consists of a header (containing pre-hash, transaction hash, and time) and a body (containing hash and transaction). The pre-hash is the hash of the previous block, the transaction hash ensures data integrity, and the time represents the transaction timestamp. The hash of each block serves as its identifier and changes if any data in the block is altered. The code provided demonstrates the implementation of a blockchain using various packages for serialization, hashing, and timestamp generation.

A simple structure of a blockchain can be understood as countless blocks connected together like a chain to form a blockchain.

The green part is called the block header, which includes (pre hash, tx hash, time).
The black part and the blue part are called the block body, which includes (hash, transaction).

The pre hash is the hash of the previous block.
Time represents the transaction time, a timestamp.
The tx hash is used to ensure that the data is not tampered with. The data of each block can theoretically be tampered with, but the hash will not match after the change.
Transaction refers to transaction information.
Finally, there is the hash value of the entire block, which is equivalent to the identifier of each block. Similarly, as long as a piece of data in the block is changed, the hash value will change.

Code above!
