## Description I'm just doing a self audit of the light client. There's a few things I've changed - Validate trust level in `VerifyNonAdjacent` function - Make errNoWitnesses public (it's something people running software on top of a light client should be able to parse) - Remove `ChainID` check of witnesses on start up. We do this already when we compare the first header with witnesses - Remove `ChainID()` from provider interface Closes: #4538
