Advanced On-chain Security: Multisig & More
summary
Covers practical on-chain defenses beyond seed phrases: how descriptors plus keys form recoverable backups, concrete decaying multi-sig and expanding multi-sig scripts that change thresholds over months, and a deployed product Revolt (N-of-N) that emulates vault behavior today. Explains pros/cons of deleting private keys vs large N-of-N, shows Lyanna desktop support for timelocks, and argues covenants (e.g. Up Vault) would simplify true Bitcoin vaults if soft-forked.
