概要

開発時に使うbitcoinのノードにはRegtestが便利です。
ローカルで動くプライベートネットワークで、ネットワークに参加するノードを自由に付け替えたりできます。

ちゃんとした、開発環境では、testnetなどを指定しますが
ローカルでの開発時には、ローカルマシン上のDiskspace/Memory/CPUなどがかなり使われてしまうばかりか、
同期に時間がかかってしまうので、Regtestで動くbitoindを立てて、その動作確認を行いました。

実施事項

bitcoindの起動

• 0.20.0 のバージョンをDockerを使って起動します。
• bitcoind -fallbackfee=0.0002 で起動します。
• bitcoin.conf は以下のようなものを含んでいます。

server=1
testnet=0
regtest=1
printtoconsole=1
disablewallet=0

[regtest]
rpcport=18332
rpcbind=0.0.0.0
rpcallowip=0.0.0.0/0

bitcoin-cliで確認

bitcoindのノードにログインして、以下を実行します。

# mining用のアドレスを作成（systemというlabelをつけておく）
bitcoin-cli getnewaddress system
