I sketched an interface:
//SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
interface IValidatorQuerier {
// Returns the validator ID list of the current subnet and the height at which it was fetched.
// The order of the list is lexicographically sorted by validator ID.
function getCurrentValidatorList() external view returns (bytes20[] calldata validatorList, uint64 pChainHeight);
// Returns the validator ID list of the subnet with [subnetID] and the height at [pChainHeight].
// The order of the list is lexicographically sorted by validator ID.
function getValidatorListAt(
bytes32 subnetID,
uint64 pChainHeight
) external view returns (bytes20[] calldata validatorIDs);
// Returns the stake weight of the validator with [validatorID] in the subnet with [subnetID] at [pChainHeight].
function getWeight(bytes32 subnetID, bytes20 validatorID, uint64 pChainHeight) external view returns (uint64 weight);
// Returns the BLS public key of the validator with [validatorID] in the subnet with [subnetID] at [pChainHeight].
function getBLSPublicKey(
bytes32 subnetID,
bytes20 validatorID,
uint64 pChainHeight
) external view returns (bytes calldata blsPublicKey);
// Returns the subnet ID of the current subnet.
function getCurrentSubnetID() external view returns (bytes32 subnetID);
// Returns the current height of the P-Chain.
function getCurrentPChainHeight() external view returns (uint64 pChainHeight);
}
