簡介

交易(Transaction)是?特幣系統(tǒng)的信息載體，最?單元。?塊(Block)就是將這些基礎(chǔ)單元打包裝箱，貼上封條，并串聯(lián)起來。巨?算?保障了塊的安全，也就保障了單個交易的安全。

類型

交易有三種常見類型：產(chǎn)量交易(Generation)，合成地址交易(ScriptHash)，通?地址交易(PubkeyHash)。該分類并?嚴(yán)格意義的，只是根據(jù)交易的輸?輸出做的簡單區(qū)分。

GenerationTX

每個Block都對應(yīng)?個產(chǎn)量交易(GenerationTX)，該類交易是沒有輸?交易的，挖出的新幣是所有幣的源頭。

ScriptHashTX

該類交易?前不是很常見，?部分?可能沒有聽說過，但是?常有意義。未來應(yīng)該會在某些場合頻繁使

?。該類交易的接受地址不是通常意義的地址，?是?個合成地址，以3開頭（對，以3開頭的也是！）。三對公私鑰，可以?成?個合成地址。在?成過程時指定nof3中的n，n范圍是[1,3]，若n=1，則僅需?個私鑰簽名即可花費(fèi)該地址的幣，若n=3，則需要三把私鑰依次簽名才可以。

PubkeyHashTX

該類是最常見的交易類型，由N個輸?、M個輸出構(gòu)成。

數(shù)據(jù)結(jié)構(gòu)

交易中存放的是貨幣所有權(quán)的流轉(zhuǎn)信息，所有權(quán)登記在?特幣地址上(PublicKey)。這些信息是全?公開的，以明?形式存儲（?特幣系統(tǒng)?的所有數(shù)據(jù)都是明?的），只有當(dāng)需要轉(zhuǎn)移貨幣所有權(quán)時，才需要?私鑰簽名來驗證。

4lock_time,鎖定時間uint32_t見下?解釋

lock_time是?個多意字段，表?在某個?度的Block之前或某個時間點(diǎn)之前該交易處于鎖定態(tài)，?法收錄進(jìn)Block。上海正規(guī)電工培訓(xùn)學(xué)校

值含義

0?即?效

500000000含義為Block?度，處于該Block之前為鎖定（不?效）

=500000000含義為Unix，處于該時刻之前為鎖定（不?效）

若該筆交易的所有輸?交易的quence字段，均為INT32最?值(0xffffffff)，則忽略lock_time字段。否則，該交易在未達(dá)到Block?度或達(dá)到某個時刻之前，是不會被收錄進(jìn)Block中的。

GenerationTX的輸?不是?個交易，?帶有coinba字段的結(jié)構(gòu)。該字段的值由挖出此Block的?填寫，這是?種“特權(quán)”：可以把信息寫?貨幣系統(tǒng)（?家很喜歡?系統(tǒng)中的數(shù)據(jù)結(jié)構(gòu)字段名來命名站點(diǎn)，例如blockchain、coinba等，這些詞的各種后綴域名都被搶注?空）。在?特幣的第?個交易中的寫?的coinba值是：
