查找下 block 400000的coinbase的交易.
第一個 Transactions 就是coinbase a8d0c0184dde994a09ec054286f1ce581bebf46446a512166eae7628734ea0a5.
使用rpc命令 getrawtransaction得到 rawtransaction.
{
"result": "01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff3f03801a060004cc2acf560433c30f37085d4a39ad543b0c000a425720537570706f727420384d200a666973686572206a696e78696e092f425720506f6f6c2fffffffff012fd8ff96000000001976a914721afdf638d570285d02d3076d8be6a03ee0794d88ac00000000",
"error": null,
"id": null
}
在使用 decoderawtransaction 解析 上一步得到的 rawtransaction,即 01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff3f03801a060004cc2acf560433c30f37085d4a39ad543b0c000a425720537570706f727420384d200a666973686572206a696e78696e092f425720506f6f6c2fffffffff012fd8ff96000000001976a914721afdf638d570285d02d3076d8be6a03ee0794d88ac00000000
結果如下:
