class ChainHandler extends ChainApi with ChainVerificationLogger

Chain Handler is meant to be the reference implementation of ChainApi, this is the entry point in to the chain project.

This implementation of ChainApi reads all values directly from the database. If you want an optimized version that caches headers locally please see ChainHandlerCached
