ValidatorRegistry •

This contract provides an onchain registry for Chronicle Protocol validators via 1-byte validators ids.

A validators id is computed as the highest-order byte of the validators address, ie uint8 validatorId = uint8(uint(uint160(validator)) >> 152);

Due to validator ids being 1 byte, the maximum number of feeds supported is 256.

Note that a set of lifted validators can be encoded in a single uint. The code refers to it as uint bloom.
