Functions

func IntToHex

func IntToHex(data int64) []byte

实现int64转[]byte

Types

type Block

type Block struct {
	TimeStamp    int64  //区块时间戳，代表区块时间
	Hash         []byte //当前区块哈希
	PreBlockHash []byte //前区块哈希
	Height       int64  //区块高度
	Data         []byte //交易数据
	Nonce        int64  //在运行pow时生成的哈希变化值，也代表pow运行时动态修改的数据
}
