If the peer (whether pruned or not itself) supports sending pruned blocks to syncing nodes, the pruned version will be sent along with the hash of the pruned data and the block weight. The original tx hashes can be reconstructed from the pruned txes and theur prunable data hash. Those hashes and the block weights are hashes and checked against the set of precompiled hashes, ensuring the data we received is the original data. It is currently not possible to use this system when not using the set of precompiled hashes, since block weights can not otherwise be checked for validity. This is off by default for now, and is enabled by --sync-pruned-blocks
