BTC

bitcoin-cli 连 btc 节点的端口是 8332，如果是 testnet是 18332，协议http。signet是38332.

signet 与 testnet的不同：testnet跟mainnet对应，是完全一样的，每一个节点都可能是出块节点，这也就导致了可能不稳定，效率低等。signet控制了出块节点，只有特定的节点是测试节点，这样就能保证整个网络的稳定性以及效率。

创建 Legacy 钱包 (非 HD Wallet) ，现在已经不推荐了

bitcoin-cli createwallet "my_legacy_wallet" false false "" false true false false`

address=$(bitcoin-cli -rpcwallet="my_legacy_wallet" getnewaddress "" legacy)
echo "New address: $address"
