Title: MultiSig: Is there such a thing as 'reverse SSS' ? (Shamir secret) Post by: Technologov2 on February 08, 2018, 03:04:57 AM 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: https://bitcointalk.org/index.php?topic=1576803.0 Title: Re: MultiSig: Is there such a thing as 'reverse SSS' ?

The thread about it is here: https://bitcointalk.org/index.php?topic=2818782.0
