Wrong. It's not SQL.

What a pity

Signatures are what makes ecash valid and anyone can validate and transfer signed ecash at will

To me, the transfer is not finalized til the fedimint reissues the ecash for its new owner

Otherwise it's a set of "bearer assets" held by several people rather than a bearer "asset" held by one

Just like the cash you like using

Except with ecash that was only handed over, not burned/reissued, two people can have a copy
