Backwards Initial Block Download Scheme

This is a scheme for discovering the current "unspent transaction output set"; it could be used to bootstrap a node that stores the UTXO set using a Cuckoo Filter.

It has the following nice properties:

  1. It starts with an empty UTXO set, but quickly discovers a large enough subset to validate a majority of new transactions (TODO: empirically measure how many blocks to be able to validate 50+% of new tx), and incrementally gets better over time.
  2. It uses a simple data structure to keep track of progress (TODO: empirically calculate maximum size of the spent set processing tip to genesis).
  3. It doesn't require any consensus-level change or require miners to maintain any extra data structures or indexes.

However, it does require downloading every single block.
