Frostr works with all of the nostr signing protocols today, but it’s still fragmented.
How do you unify them? Keep it all interoperable, and keep them connected? These are big problems to solve still!
Discussion
FROST unifies how signatures are produced. It doesn’t unify who the identity is over time. Fragmentation happens because keys are treated as identities. You need a stable authority anchor above signing schemes, otherwise every signer model fragments the graph. Interop comes from separating identity continuity from signing mechanics.
