I've read about secret sharing as a means of doing multisig in Monero, and I know services like Haveno & RINO implement 2-of-3 wallets as a service (for exchange escrow and shared custody respectively). I'm interested in a different sort of implementation, one that doesn't rely on a third party host.

Nunchuk.io, for example, develops a BTC wallet that allows multiple users to collaboratively create multisig wallets & share custody of bitcoin. They can sign/approve transactions via an integrated messenger (which is third party hosted, but doesn't technically need to be afaik). This has multiple use cases, but it interests me primarily as a trustless escrow service between individuals.

As a non-programmer, I'm curious if anything about XMR secret sharing prevents the development of an equivalent application for Monero. Haveno and RINO have their own use cases, but I'd be more interested in something that can work between individual users without any third party company/service/platform.

The fact that multisig was not widely used yet, was indirectly related to the unfortunate CCS Wallet Incident, which happened a few months ago, as well.

@ErC (ErCiccione), a contributor, commented elsewhere a few days ago:

This is a bit of a dog biting its tail. Multisig was shipped and has been live for a long time. Nobody really used it, so it ended up being unstable and full of problems, but that came out only relatively recently (couple of years ago) when services started to build on it.

People are now saying, “If multsig had been used…” “should have” “could have” (Hindsight is 20/20 😢). Anyway, fluffypony replied, “when it reached a level of maturity (this year? late last year?) it should have been prioritized.”

We can expect that multisig will be now more prioritized and to be carefully tested and tuned, soon to be available more generally, if not right now. So perhaps the answer to your question is, “No, but maybe soon…”?

@Saki @japananon

Multisig is like the gpg of email, best practice in theory but rarely used due to usability.

AFAIK it's still only available via the CLI version of monero wallet?

Rino.io has a great multisig gui.
