case class ChainHandlerCached(blockHeaderDAO: BlockHeaderDAO, filterHeaderDAO: CompactFilterHeaderDAO, filterDAO: CompactFilterDAO, stateDAO: ChainStateDescriptorDAO, blockchains: Vector[Blockchain], blockFilterCheckpoints: Map[DoubleSha256DigestBE, DoubleSha256DigestBE])(implicit chainConfig: ChainAppConfig, executionContext: ExecutionContext) extends ChainHandler with Product with Serializable

An optimized version of ChainHandler that avoids database reads for determining what the best block header is. This should be used with care as it is possible the cached blockchains may be out of date! Unless you know what you are doing, you should probably use ChainHandler
