func (*BlockSyncer) Sync ¶
func (s *BlockSyncer) Sync(ctx context.Context) error
Sync fetches (up to) BlocksToFetch blocks from peers using Client and writes them to disk. the process begins with FromHash and it fetches parents recursively. fetching starts from the first ancestor not found on disk
TODO: We could inspect the database more accurately to ensure we never fetch any blocks that are locally available. We could also prevent overrequesting blocks, if the number of blocks needed to be fetched isn't a multiple of blocksPerRequest.
