トランザクションの生成からビットコインの送信まで
今日は、いよいよビットコインを送信してみます！ 送信するには、bitcoin-cliコマンドでは、ちょっと手間がかかります。 メインのマシンのノードからサブのマシンのノードへの送金が目標。
1.トランザクションの生成
ビットコインの送信をするために、まずは、トランザクションを作ります。
$ bitcoin-cli createrawtransaction '[{"txid":"c96716b9e6737df8cc6e6c98483bfffb05722923d87489f560cc0f774e9b13cc", "vout":1}]' '{"2NDgAf7qsfggo7aNU2BRXG6G7EQWLXh85FC":0.05, "2MsfC335uWwM7yyFcv61B3w5PjwVx1VtgCy":0.03}'
0200000001cc139b4e770fcc60f58974d823297205fbff3b48986c6eccf87d73e6b91667c90100000000ffffffff02404b4c000000000017a914e01a2276131210a6fe444ead747cbead075c4e4e87c0c62d000000000017a91404885a6a6d1dab5e30bd54d04fdb9f5927e3825f8700000000
見た目があれですけどJSON形式でトランザクションを記述します。
ここでは、受け取ったビットコインのトランザクションtxid:c967...を使って、送り先アドレス"2NDgA..."に0.05bitcoinを送ります。 おつりにあたる0.03bitcoinを自分のアドレス"2MsfC..."に送るつまり自分に戻します。 そして、余った分は、手数料としてとられるようです。
念のために作ったトランザクションを確認してみます。
$ bitcoin-cli decoderawtransaction 0200000001cc139b4e770fcc60f58974d823297205fbff3b48986c6eccf87d73e6b91667c90100000000ffffffff02404b4c000000000017a914e01a2276131210a6fe444ead747cbead075c4e4e87c0c62d000000000017a91404885a6a6d1dab5e30bd54d04fdb9f5927e3825f8700000000

2.トランザクションの署名
送信するためには、ウォレットの秘密鍵で署名する必要があります。
まずは、暗号化されているウォレットをパスワードで一時的に(360秒)復号化しておきます。
$ bitcoin-cli walletpassphrase xxxxxxxx 360
signrawtransactionメソッドで署名っと。
$ bitcoin-cli signrawtransaction 0200000001cc139b4e770fcc 60f58974d823297205fbff3b48986c6eccf87d73e6b91667c90100000000ffffffff02404b4c0000 00000017a914e01a2276131210a6fe444ead747cbead075c4e4e87c0c62d000000000017a9140488 5a6a6d1dab5e30bd54d04fdb9f5927e3825f8700000000 error code: -32 error message: signrawtransaction was removed in v0.18. Clients should transition to using signrawtransactionwithkey and signrawtransactionwithwallet
あらら、エラーになってしまった。signrawtransactionは、もう、古いメソッドみたいです。 調べてみるとsignrawtransactionwithwalletメソッドがほぼ同じ動きみたいです。
$ bitcoin-cli signrawtransactionwithwallet 0200000001cc13

scriptSigに署名が入ったみたいですね。
3.ビットコインの送信
いよいよビットコインを送信します！

categoryがsendでamountがマイナスのトランザクションが見えます。
受け取り側マシンは、
$ bitcoin-cli listtransactions
[

承認されたみたい！一応残高を確認すると
$ bitcoin-cli getbalance 0.05000000
おお、ちゃんと受け取れてる！
もう一度送信側でトランザクションを確認すると

差額がfee手数料として取られた形だけど、手数料の額って任意なのかな？？？
