Is there such a thing as 'reverse SSS' ? (Shamir secret sharing)
I think about constructing a multisig address from multiple pubkeys (m-of-n) in a deterministic way.
That is, in 2-of-3 system, having 2 pubkeys (or 2 pubkey hashes) to construct a multisig hash.
Goals:
1. Invent as 'Pay to PubKey Hash' (P2PKH) address that works with MultiSig. (rather than pay-2-script)
2. Sign message from MultiSig address. (currently undefined and doesn't work)
Original talk:
Q: Is it possible to sign a message from a multisig address?
A: No, and here is why:
