"Expect the unexpected!"

This is a fork of bitcoin with the goal of making it easy to do a deep investigation of the value of proposed consensus (and to a lesser extent, relay policy) changes. To do so, we disable support of non-controlled chains (ie, mainnet and testnet; only leaving support for regtest and signet), change the way activation works (TODO: document this in a BIP), and aggressively merge proposed changes. To keep things relatively simple, we base changes on released versions of Bitcoin Core.
