Well I've been thinking a lot about the future of multi-sig. Obviously with an individual account on the client you have control of both signatures. In a joint account you have control of 1 sig and your partner/counterparty has control of the other.
Whats good in theory will never work in practice especially with BAY. If u look around u will notice a countless number of attempts to implement multisig, look at monero for instance. Calling this whitespacing. Its chattering on a dead thread.
Multi-sig is already functioning in BitBay. The Halo Client has had joint accounts for the last 2 years.
David's going to release an small update very soon to alleviate some networking issues with the client and QT seed nodes.
After that I'd be more than happy to test out a joint account with anyone here.
We could create an account and then we could use that account to accept the BitBay faucet built into the marketplace.
You'd get to see first hand how it works at no risk - the faucet is free obviously. After that we could transfer the coins to your personal account and I'd show you how it's done with either manual signature or auto signature.
Like I said previously, in the future all it would take is to tweak the joint account to make it more one-sided. That way if you wanted to transfer coins to an exchange or money manager, you'd have a trustless setup where you still have full control of your coins even if something happened to your account partner - tweaked by locking one side of the account in auto-sig mode.
The joint account is on my list of tutorial videos to make.
But yeah I've tested it out with Munti and it works great and is very user friendly. It will be 100% complete on David's next 'major' update! That's where you will be able to create a joint account with yourself so you can have a private key on 2 separate devices. That way you could 'cold' stake your coins. The odds of a hacker stealing those coins in such a setup would be damn near impossible as they'd have to gain access to 2 computer devices simultaneously, then find your keys, then break through the passphrases!
