内置合约

Conflux引入了几个内嵌的内置合约，以便更好地进行系统维护和链上治理。 Now Conflux has seven internal contracts: AdminControl contract, SponsorWhitelistControl contract and Staking contract are introduced from the beginning, ConfluxContext, PoSRegister, ConfluxContext are introduced at v2 hard-fork, ParamsControl is introduced at v2.1 hard-fork. 这些合约提供了在这里定义的solidity函数api。 这些函数只能通过CALL或STATICCALL操作来调用。 使用操作CALLCODE或DELEGATECALL与内部合约交互将触发错误。

这7个内置合约的地址如下所示：
