多签账户

多签账户

本文档介绍多签账户的使用，包括如何通过 Rooch CLI 在链上创建多签账户，以及如何发起多签交易，如何签名交易，如何广播交易。

概述

Rooch 作为 Bitcoin 的 L2，Rooch 提供了 L1 交易和 L2 交易的多签功能。本文首先演示 L1 交易，即演示 Bitcoin 的原生资产 BTC 的多签交易，然后演示 L2 交易，即演示 Rooch 的 RGAS 的多签交易。

准备账户公钥

接下来准备 3 个账户来演示多签账户的功能。

通过 rooch account create 创建好账户，通过 rooch account list --json 可以查看对应账户的公钥。

$ rooch account list --json

L1 交易演示

这次我们将多签地址上的 BTC 转移到 tb1pmmx3fk9e2umvshm4r8j6va9xcrmp2s75r96upfxxyhp8mwyfwwssrql720 这个地址。

创建多签

rooch account create-multisign -t 2 -p $Pubkey1 -p $Pubkey2 -p $Pubkey3
  • -t 或 --threshold 指定多签的门限数。假如，指定 3 个账户生成的多签账户，指定 -t 2 则表示 3 个账户中需要任意 2 个账户共同签名交易，这笔多签交易才能够验证。
  • -p 或 --public-keys 指定参与多签的账户公钥。
$ rooch account create-multisign -t 2 -p 0x022a88ddcf585a398e62be5d4d47d4f5ae5e818febaf04bfa465fd6a83c7aa6b9f -p 0x02a2f2aba75dd50503c91c3c7f18ee16c14b0d94fb3b3951a612df2524788f3629 -p 0x035af3f3c32cf418da0ace8df6bca9dd9e231353dcc2d53b31138b0256c897d79d

我们在 Discord 给多签地址领取 tBTC 后，将 100 sats 的 tBTC 转账到一个没有余额的账户，这里演示的目标账户为 tb1pmmx3fk9e2umvshm4r8j6va9xcrmp2s75r96upfxxyhp8mwyfwwssrql720。

# 切换到要转账的目标地址
$ rooch account switch --address tb1pmmx3fk9e2umvshm4r8j6va9xcrmp2s75r96upfxxyhp8mwyfwwssrql720
The active account was successfully switched to `rooch1hh9p0twq7yze06tys4lp2dzh3k6s4jgrcu68vqnr5ku8cwuaprjq0y8pml`
 
# 查看目标地址的余额
$ rooch account balance
                                              Coin Type                                                |      Symbol      | Decimals |             Balance

可以看到目标地址的余额为 0 sats。

生成多签交易

rooch bitcoin build-tx --sender $multisign_bitcoin_address -o $to_address:amount_sats
  • --sender 指定多签账户地址。
  • -o 指定交易输出，即转账的比特币地址和比特币的数量（单位为 sats），这里使用 : 分隔。
$ rooch bitcoin build-tx --sender tb1przxwx6xdyehpnspdr70jaqjm4g62dedcm4gcvf62qu6xjae6e8tq4mpqvn -o tb1pmmx3fk9e2umvshm4r8j6va9xcrmp2s75r96upfxxyhp8mwyfwwssrql720:100

  "output_type": "psbt",
  "path": "/tmp/305da9d77a2af176.psbt"
}

此时这笔多签交易存放在 /tmp/305da9d77a2af176.psbt 这个文件里，接下来我们会使用多签参与者的账户来对这笔交易进行签名。

签名交易

rooch bitcoin sign-tx -s $Pubkey1_address /tmp/xxxxx.psbt
rooch bitcoin sign-tx -s $Pubkey2_address /tmp/xxxxx.psbt
  • -s 指定多签参与者公钥的地址。

  "path": "/tmp/305da9d77a2af176.tx"
}

当多签交易满足门限数后，我们就可以将这笔多签交易广播出去，交易就会上链了。

广播交易

rooch bitcoin broadcast-tx /tmp/xxxxx.tx

多签参与者对多签的交易签名后，会在相同的目录生成一个 .tx 文件，此处为 /tmp/305da9d77a2af176.tx，这个文件存放着这笔多签交易的内容，我们将这笔交易广播出去，就会上链了。

[joe@mx ~]$ rooch bitcoin broadcast-tx /tmp/305da9d77a2af176.tx
"59142915d9a1f301dcd26120fe747a18a9e577cb9d357eae76f12a7ad7a95d30"

接下来，我们检查一下目标账户的余额：

$ rooch account balance
                                              Coin Type                                                |      Symbol      | Decimals |             Balance

目前，我们的目标账户已经有了 100 sats 的 BTC 了。

L2 交易演示

这次我们将多签地址上的 RGAS 转移到 tb1p488sz4vv4rnc267hd0m7st5dufpmtzv4nw70r7exyfwz60s3rhsqca94sg 这个地址上，此时这个地址上还没有这个币：

$ rooch account balance --address tb1p488sz4vv4rnc267hd0m7st5dufpmtzv4nw70r7exyfwz60s3rhsqca94sg

我们将演示从多签账户转 5000 RGAS 到上面这个账户。

Partially signed transaction is written to "/tmp/b034cf66a671f0f7.1.psrt"
You can send the partially signed transaction to other signers, and sign it later with `rooch tx sign /tmp/b034cf66a671f0f7.1.psrt`

当第一个参与者签名后，会生成另外一个文件，位于 /tmp/b034cf66a671f0f7.1.psrt，接下来的签名者必须对这个新的文件签名。

第二个参与者，这里为 tb1p488sz4vv4rnc267hd0m7st5dufpmtzv4nw70r7exyfwz60s3rhsqca94sg：

$ rooch tx sign -s tb1p488sz4vv4rnc267hd0m7st5dufpmtzv4nw70r7exyfwz60s3rhsqca94sg /tmp/b034cf66a671f0f7.1.psrt

You can submit the transaction with `rooch tx submit /tmp/b034cf66a671f0f7.rooch1vrg7lzdml74mvhnpke9mfrvgn0esnedf3l6sn52t29qs2j5zy35s6qdlty.srt`

这里会提示已经收集了多少个签名，以及是否签名这笔交易。

签名结束后，会得到一个已经完成多多签的交易文件 /tmp/b034cf66a671f0f7.rooch1vrg7lzdml74mvhnpke9mfrvgn0esnedf3l6sn52t29qs2j5zy35s6qdlty.srt，命令行会打印将交易提交到 Rooch 链上的提示。

提交交易

只需将刚才的多签交易提交到链上即可：

$ rooch tx submit /tmp/b034cf66a671f0f7.rooch1vrg7lzdml74mvhnpke9mfrvgn0esnedf3l6sn52t29qs2j5zy35s6qdlty.srt

看到执行成功的信息后，说明我们的多签交易已经执行成功！

我们查询一下账户：

$ rooch account balance --address tb1p488sz4vv4rnc267hd0m7st5dufpmtzv4nw70r7exyfwz60s3rhsqca94sg
                                              Coin Type                                                |      Symbol      | Decimals |             Balance

我们的目标账户已经拥有了刚才转账的 5000 RGAS 了。

这个就是 L2 多签交易的具体流程了，跟 L1 交易很相似，签名过程中需要注意命令和传递的文件名。

总结

至此，相信你已经熟悉 Rooch 在命令行下如何发送多签交易的整体流程了！
