OK, to make progress on this work I need a few decisions (Gavin?)
1) Shall we do it?
What problem does it solve?
If the problem it will solve is it will only take 4 hours to download
the entire blockchain next year instead of taking 16 hours then no, I
don't think we should do it, both 4 and

My solution was to simply state that vertexes that happened to cause the
tree to be unbalanced would be discarded, and set the depth of inbalance
such that this would be extremely unlikely to happen by accident. I'd
rather see someone come up with something better though.
I hope that someone else here would chime in on the issue raised in the
thread, about using a tree-structure that has multiple valid
configurations for the same set of unspent-TxOuts. If you use any
binary tree, you must replay the entire history of insertions and
deletions in the correct

A PATRICIA tree/trie would be ideal, in my mind, as it also has a
completely deterministic structure, and is an order-of-magnitude more
space-efficient. Insert, delete and query times are still O(1).
However, it is not a trivial implementation. I have occasionally looked
