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. These contracts provide solidity interfaces defined here. 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。
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7个内置合约的地址如下所示：

📄️ AdminControl
概览
📄️ SponsorWhitelistControl
Conflux实现了赞助机制，来补贴智能合约的使用。 这允许余额为零的新账户调用智能合约，前提是执行操作得到赞助（通常由Dapp运营者提供）。 内部的 SponsorWhitelistControl 合约记录了智能合约的赞助信息。
📄️ Staking
概览
📄️ ConfluxContext
This contract can be used in Solidity contract to query Conflux Core network info including:
📄️ PoSRegister
这个合约用于让用户参与PoS链。 需要与这个合约交互才能成为PoS节点。 这个合约提供了几个方法来增加或减少PoS投票：
📄️ CrossSpaceCall
CIP-90 引入了一个新的内置合约：CrossSpaceCall. CrossSpaceCall enables CFX and data to be transferred between the two spaces.
📄️ ParamsControl
ParamsControl位于地址0x0888000000000000000000000000000000000007，具有以下接口。 它可以用来参与链参数投票。
