Bitcoin and quantum computing: counting for yourself with a node
The third piece of the «Bitcoin and quantum computing» family: not the numbers, but how to redo them. Every command needed to count for yourself, with your own node, how many coins already have their public key in view: the census of the UTXO set by lock type and by age, the pass that counts reuse, the outpoint index, the check of your own addresses without handing them to anyone. Three levels, from minutes to days, that can be left half done while still giving a verifiable result. Every step carries the real output of our own run at block 957,301 and the fingerprints anyone must land on by redoing it. Public code, MIT licence.
