The first two articles simply implement blockchain creation and proof of workload, but they are all in memory. The actual blockchain should be stored permanently, which makes sense. A permanent blockchain storage is started below.

Let's implement the Serialize method of block (error handling is omitted here for brevity):
Func (b *block) Serialize () []byte {
var result bytes. Buffer
Encoder: = gob. Newencoder (result)
err: = Encoder. Encode (b) return result
. Bytes ()
}
This section is more intuitive: first, we define a buffer to store the data after serialization. We then initialize a GOB encoder and encode the block, and the result is returned as a byte array.
Next, we need a serializabl

Obviously, this is a very inflexible form. For example: "def addon (x, y): Return x +Y ", the addon function defined here can be called in the form of addon (), which means that the parameter X will be set

Please refer to the Installation Docker container and Docker-compose operating environment.
The easiest place to use Docker-compose is to automatically pull images and build applications automatically from the Docker hub using the docker-compose.yaml that someone else has already prepared.
