Hey guys,
I get that to claim the airdrop you need to sign your Semux address with your Bitcoin wallet.
But how do the Semux team then know your Bitcoin address in order to check your balance?

Basically is it possible to derive the public address if you know the message that was signed and the signed message itself?
Can anyone point me in a direction where i can read more on this as Google isnt really bringing anything up?

Cheers
