交易相關(guān)數(shù)據(jù)結(jié)構(gòu)

Block

區(qū)塊，orderer 生成的區(qū)塊（賬本存儲(chǔ)的區(qū)塊結(jié)構(gòu)）

Block

|    |_Envelope     # Data 里面的 [][]byte 就是 Envelop 數(shù)組
 \_Metadata #BlockMetadata

Envelop

交易信封，交易提案及背書結(jié)果，客戶端發(fā)送給 orderer 出塊的數(shù)據(jù)結(jié)構(gòu)

配置存儲(chǔ)相關(guān)結(jié)構(gòu)

存儲(chǔ)在配置塊中的配置數(shù)據(jù)結(jié)構(gòu) （層次關(guān)系： Block --> Envelop --> ConfigEnvelop）
orderer 的 genesisblock 就是這樣的一個(gè)配置塊。

配置更新相關(guān)結(jié)構(gòu)

用于提交配置更新交易的數(shù)據(jù)結(jié)構(gòu)（客戶端提交給 orderer 進(jìn)行通道配置更新，比如創(chuàng)建channel，更新channel等）
