I'm not so sure about that last part. With the way DB were manipulating bets I think they would have been able to hurt a lot of players and investors even if the cold wallet was co-signed.
If it was cosigned, JoeMattie would have been paid out. And DB wouldn't have able to just move the funds to where ever they wanted.
And to BayAreaCoin, I know dooglus isn't cosigning. I just mean, if dooglus had cosigned DB's funds, then it would have been good.
I guess I don't understand co-signing then. Would the cold wallet co-signer approve every large withdrawal directly to player's address? I thought that funds go from cold wallet to hot wallet if needed and are withdrawn from the hot wallet. I can see how co-signing can ensure that the cold wallet balance roughly corresponds to bankroll and the owners don't just take the coins and run, but I don't see how it could prevent the site from cheating its players by bet manipulation or cheating its investors by playing against the house.
You are confusing what we are talking about with a multisignature.
Signing a wallet just proves that you are the one with that priv key and a multisignature address means you hold a part of the key.
I know what a signed message is. I was replying to caga's post about DB multisig proposal that was never implemented.
