The Blockchain Reactor's high level responsibility is to request blocks from peers or provide them The Blockchain Reactor's high level responsibility is to enable peers who are
with blocks, validate and persist the blocks to disk and play blocks to the ABCI app. far behind the current state of the consensus to quickly catch up by downloading
many blocks in parallel, verifying their commits, and executing them against the
