OP_CHECKDATASIGVERIFY 不工作

April 28, 2019

我正在嘗試生成簽名並將其作為 regtest 網路上 P2SH 地址的一部分通過 OP_CHECKDATASIGVERIFY 傳遞。這導致以下結果：

公鑰：

036ab9012ecc30c30f9220d862a56c5c99b1a08d783be605406fbde8ece2807b2f

簽名：

7f7f9af76890ca09afc49e458a1b23fdd2e29cc061693c4b326b16e40728091a

客戶端（bitcore-lib-cash）表示簽名驗證並符合 LowS 檢查，但在送出到網路時簽名失敗：

bitcore-lib-cash 0.19.0 => 可以驗證簽名

比特幣-ABC v190100 =>16: mandatory-script-verify-flag-failed (Signature must be zero for failed CHECK(MULTI)SIG operation)

通過 bch-deb 調試：https ://hastebin.com/gelitojuge.rb

這裡有什麼不尋常的地方嗎？

更新：3/20/19 - 注意，這是一個不同的、簡化的完整範例 tx

**原始 TX：**傳入了額外的變數，但目前只使用了幾個。
