Don't mean to derail the thread i'm just wondering something... if the trustless coin uses 2 of 2 that means a private key is on the coin and you also have a private key. You need both to spend the funds. But how do you get hold of the public address so you can load the coin properly without knowing both of the keys? Can you derive a public address from just half the key?
Anyone who orders a multisig coin needs to send us the full public key they want linked to the multisig address. Then we will generate the address and the public address with QR codes etc will be sent in the package separately. On a piece of paper.
For aftermarket purposes anyone will be able to verify from the other private key that it is part of the multisig solution and can be used to access the funds. In case someone wants to sell a multisig Denarium. It can be done and will be secure as long as the coin and its hologram is secure.
