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
permissio | account | weight | threshold |
---|---|---|---|
owner | 2 | ||
@user1 | 1 | ||
@user2 | 1 | ||
active | 1 | ||
@user1 | 1 | ||
@user2 | 1 |
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
| 账号 | 权限|公钥 |私钥 |
| ------------ | ------------ | ------------ |
| popo11111111 | owner | EOS81WjiHefR6c5VKYjvdSat68RDJ3qGPgCckJqG3pXbDbVjZR5QB | 5JAxr3bM6DwwtcKJ7aVydpoaSA2oyiZ94PjqTpW6uXDZ41VuK22|

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

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

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

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

"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。
