-       * blockchain.  The block ids are more dense near the end of the chain where because we are

-       *
-       * Second, when a peer replies to our initial synopsis and gives us a list of the blocks they think
-       * we are missing, they only send a chunk of a few thousand blocks at once.  After we get those
-       * block ids, we need to request more blocks by sending another synopsis (we can't just say "send me
-       * the next 2000 ids" because they may have switched forks themselves and they don't track what
