學好Go語言走遍天下都不怕。以下程式碼建立了一個非常原始的電子賬本：

package main

import (
    "bytes"
    "crypto/sha256"
    "fmt"
    "strconv"
    "time"
)

type Block struct {
    Timestamp     int64
    Data          []byte
    PrevBlockHash []byte
    Hash          []byte
}

func (b *Block) SetHash() {
    timestamp := []byte
 
(strconv.FormatInt(b.Timestamp, 10))
    headers := bytes.Join([][]byte{b.PrevBlockHash, b.Data, timestamp}, []byte{})
    hash := sha256.Sum256(headers)
    b.Hash = hash[:]
}

/*
    初始化第一個塊
*/
func NewBlock(data string, prevBlockHash []byte) *Block {
    block := &Block{time.Now().Unix(), []byte
 
(data), prevBlockHash, []byte{}}
    block.SetHash()
    return block
}

type Blockchain struct {
    blocks []*Block
}

/*
    新增 區塊
*/

func (bc *Blockchain) AddBlock(data string) {
    prevBlock := bc.blocks[len(bc.blocks)-1]
    newBlock := NewBlock(data, prevBlock.Hash)
    bc.blocks = append(bc.blocks, newBlock)
}

func
 
 NewGenesisBlock() *Block {
    return NewBlock("Genesis Block創始塊", []byte{})
}

/*
    用創始塊建立一個區塊鏈的函式
*/
func NewBlockchain() *Blockchain {
    return &Blockchain{[]*Block{NewGenesisBlock()}} /*我不太理解這種語法,層層深入？
YuloYu 在評論中說:這個地方是，把[]*Block{NewGenesisBlock() 生成的塊，把塊放到這個數組裡面。*/
}

func main() {
    /*
       初始化
    */
    bc := NewBlockchain()

    /*
       新增記錄
    */
    bc.AddBlock("Send 1 BTC TO L")
    bc.AddBlock("Send 2 BTC to R")

    /*
      檢視我們最終儲存結果
    */
    for _, block := range bc.blocks {
        fmt.Printf("Prev: hash:%x\n", block.PrevBlockHash)
        fmt.Printf("Data: %s\n", block.Data)
        fmt.Printf("Hash: %x\n", block.Hash)
        fmt.Println()
    }
}
