# ConfluxContext ConfluxContext 内置合约可用于在 Solidity 中获取当前网络信息,目前包含:`epochNumber`, `posHeight`, `finalizedEpochNumber` ```js pragma solidity >=0.4.15; contract ConfluxContext { /*** Query Functions ***/ /** * @dev get the current epoch number * @return the current epoch number */ function epochNumber() public view returns (uint256) {} /** * @dev get the height of the referred PoS block in the last epoch ` * @return the current PoS block height */ function posHeight() public view returns (uint256) {} /** * @dev get the epoch number of the finalized pivot block. * @return the finalized epoch number */ function finalizedEpochNumber() public view returns (uint256) {} } ```
