abstract class FilterSync extends ChainVerificationLogger

A class that is meant to expose and api to sync GolombFilters and FilterHeaders from an external data source. The important thing to implement is

getFilterFunc: BlockHeader => Future[GolombFilter]

which will allow us to sync our internal filters against.

It should be noted you are entirely trusting the provider of the getFilterFunc as you aren't able to validate the result against another peer that as BIP157 specifies
