Functions

func GetTxTreeRoot

func GetTxTreeRoot(txs []*base.Transaction) []byte

GetTxTreeRoot 获取交易根，这个根可以用来检查区块中的交易 新建一个空的 mpt, 插入所有 transactions 并计算 root hash

Types

type BlockChain

type BlockChain struct {
	Config          *Config                   // 区块链配置
	CurrentBlock    *base.Block               // 最新的区块
	BlockStorage    blockStorage.BlockStorage // 区块持久化
	StateStorage    stateStorage.StateStorage // 状态树持久化
	Trie            *mpt.Trie                 // 状态树
	TransactionPool *base.TransactionPool     // 交易池
