eos系统合约介绍 — 提案合约eosio.msig (上)

2018-09-25 14:00:00

简介

本篇将为大家介绍eos另一个系统合约eos.msig的主要功能和源码实现细节。eos.msig是eos的提案合约，同样也是cleos multisig命令调用的系统合约，可用于提案、通过/不通提案、执行多重签名交易等功能。由于涉及内容较多，介绍将分为上下两篇，上篇将围绕eos账户权限、cleos multisig命令的使用这几个方面进行介绍，下篇则会为大家介绍eosio.msig的源码实现

Eos账户权限

回顾一下之前的文章，一个账户最基本的权限owner和active是由公私钥对控制的，然而，eos丰富的权限控制方式，还允许我们将一个账户的权限，下放给其他的账户。比如下面的经典例子：
账户popo的权限情况

permissioaccountweightthreshold
owner 2
@user11
@user21
active 1
@user11
@user21

我们将一步一步，通过命令行操作的方式来为大家介绍eos权限的应用。

1.我们分别创建三个账户popo11111111、zoin11111111、zoin22222222，每个账户使用不同的公私钥对。
分别创建6对公私钥，分别用于三个账号的owner和active权限

cleos create key --to-console

2.下面开始创建三个账号

cleos system newaccount 已有账号 将要创建的账号 ownerkey  activekey  --stake-net '0.1 EOS' --stake-cpu '0.1 EOS'  --buy-ram-kbytes 4000

利用我们上面文章《以传统的WEB开发方式，来举例理解Dapp开发》中已经在麒麟测试网创建的账号cryptokylinq，并在麒麟测试网来创建其他账号。

3.将popo11111111的owner权限交出，由zoin11111111和zoin22222222的owner权限控制。每个权限的权重weight是1，而门槛threshold是2，即使用popo11111111的owner权限发送交易，需要zoin11111111和zoin22222222进行多重签名才行

cleos multisig命令

EOS账户这一节，我们将popo11111111账户的owner和active权限交给了zoin11111111和zoin22222222账户，则popo11111111账户原来的公私钥对就失效了，交易的发送需要zoin11111111和zoin22222222账户授权。

额外提一句，主网启动后，超级节点们会将eosio账户的权限交给eosio.prods账户，而eosio.prods账户是由21个超级节点的账户联合控制的，需要15个节点联合签名才能使用eosio账户，可以避免拿管理员权限作恶的现象

下面，我们就要介绍cleos multisig命令如何调用eosio.msig合约进行提案、发送多重签名的交易。

1.zoin11111111发起一个转账提案，提案名是transferpopo，将popo11111111账户中的10EOS转给cryptokylinq账户，这之前需要保证popo11111111账户有币。
先给popo11111111转入点EOS

cleos -u http://kylin.fn.eosbixin.com push action eosio.token transfer '["cryptokylinq", "popo11111111","10.0000 EOS","test"]' -p cryptokylinq

再导入zoin11111111的active的私钥

suroudeMacBook-Pro:~ surou$ cleos wallet import

详细分析下cleos multisig propose命令参数
- proposal_name：提案名

  • requested_permissions：提案审批通过需要的权限，这里需要zoin11111111和zoin22222222的active权限
  • trx_permission：提案执行需要的权限，需要popo11111111的active权限就能发起转账
  • contract：提案调用的合约账户，转账使用eosio.token账户合约
  • action：提案调用的合约方法，转账使用transfer方法
  • data：具体数据
  • proposer：提案发起人，zoin11111111发起

- proposal_expiration：提案的有效时间

2.查看提案交易cleos multisig review <proposer> <proposal_name>

}

3.查看提案审批情况，provided_approvals为空表示尚未审批，request_approvals表示需要哪些权限进行审批
cleos get table eosio.msig <proposer> approvals

suroudeMacBook-Pro:~ surou$ cleos -u http://kylin.fn.eosbixin.com get table eosio.msig zoin11111111 approvals
{
  "rows": [{
      "proposal_name": "transferpopo",
      "requested_approvals": [{
          "actor": "zoin11111111",
          "permission": "active"
        },{
          "actor": "zoin22222222",
          "permission": "active"
        }
      ],
      "provided_approvals": []
    }
  ],
  "more": false
}

4.通过提案 cleos multisig approve 提案人 提案 权限

  • zoin11111111通过提案
suroudeMacBook-Pro:~ surou$ cleos -u http://kylin.fn.eosbixin.com multisig approve zoin11111111 transferpopo '{"actor": "zoin11111111", "permission": "active"}'  -p zoin11111111@active
executed transaction: bcc0495b88d7b897853af11ace59029a32f16f1727de04e4c1fa7fc85e7df1dc  128 bytes  1091 us
#    eosio.msig <= eosio.msig::approve          {"proposer":"zoin11111111","proposal_name":"transferpopo","level":{"actor":"zoin11111111","permissio...

查看提案审批情况

suroudeMacBook-Pro:~ surou$ cleos -u http://kylin.fn.eosbixin.com get table eosio.msig zoin11111111 approvals
{
  "rows": [{
      "proposal_name": "transferpopo",
      "requested_approvals": [{
          "actor": "zoin22222222",
          "permission": "active"
        }
      ],
      "provided_approvals": [{
          "actor": "zoin11111111",
          "permission": "active"
        }
      ]
    }
  ],
  "more": false
}
  • zoin22222222通过提案
suroudeMacBook-Pro:~ surou$ cleos -u http://kylin.fn.eosbixin.com multisig approve zoin11111111 transferpopo '{"actor": "zoin22222222", "permission": "active"}'  -p zoin22222222@active
executed transaction: 62ef04a0ee345ac604ca9fe7be034a0cb69524b1ed146e22c44a806a03337919  128 bytes  633 us
#    eosio.msig <= eosio.msig::approve          {"proposer":"zoin11111111","proposal_name":"transferpopo","level":{"actor":"zoin22222222","permissio...

查看提案审批情况

suroudeMacBook-Pro:~ surou$ cleos -u http://kylin.fn.eosbixin.com get table eosio.msig zoin11111111 approvals
{
  "rows": [{
      "proposal_name": "transferpopo",
      "requested_approvals": [],
      "provided_approvals": [{
          "actor": "zoin11111111",
          "permission": "active"
        },{
          "actor": "zoin22222222",
          "permission": "active"
        }
      ]
    }
  ],
  "more": false
}

5.执行提案cleos multisig exec <proposer> <proposal_name> -p 谁想执行都可以
执行前查看账户

  • cryptokylinq 余额4,148.3135 EOS
  • popo11111111 余额 10 EOS
suroudeMacBook-Pro:~ surou$ cleos -u http://kylin.fn.eosbixin.com multisig exec zoin11111111 transferpopo -p zoin11111111
executed transaction: caaa900536463207713f6af031ee315125d993f0af56ea91aafff3dcdf8b1353  160 bytes  1098 us
#    eosio.msig <= eosio.msig::exec             {"proposer":"zoin11111111","proposal_name":"transferpopo","executer":"zoin11111111"}

执行完成后查看账户

  • cryptokylinq 余额4,158.3135 EOS
  • popo11111111 余额 0 EOS

且提案将被自动删除

suroudeMacBook-Pro:~ surou$ cleos -u http://kylin.fn.eosbixin.com get table eosio.msig zoin11111111 approvals
{
  "rows": [],
  "more": false
}

并注意到，该笔转账没有交易记录actions 额，是不是在某些情况，需要隐藏交易记录时，可以通过此方法。。。

使用场景

某个账户发起一个提案后，需事先明确指定哪些账户/权限，必须全部通过审核后，合约动作才能被执行。

常见问题

  • 提案操作很消耗CPU Error 3080004: Transaction exceeded the current CPU usage limit imposed on the transaction
cleos -u http://kylin.fn.eosbixin.com system delegatebw cryptokylinq zoin11111111 "0 EOS" "10 EOS"
  • 执行提案时，可能出现下面未知错误


需要部署eosio.system系统合约，并开启提案合约的功能即可解决（具体原理会在介绍eos.system合约的时候介绍）

cleos push action eosio setpriv '["eosio.msig", 1]' -p eosio

后记

本篇为大家介绍了eos的账户权限，以及eosio.msig提案合约如何通过cleos multisig调用使用，如何发起提案、审批提案等。别走开，下一篇将深入源码，分析eosio.msig提案合约是怎么写的。
