What prevents the creditor from signing a transaction that is neither a val=
id MT nor a GT?
Nothing.
In Lightning, sure one side can sign a transaction that is not a valid comm=
itment transaction, but good luck getting the other side to *also* sign the=
transaction; it will not.
Thus, you need n-of-n.
1-of-1 is simply not secure, full stop, you need to redesign the whole thin=
g to use *at least* 2-of-2.
At which point you will have reinvented Lightning.
Otherwise, you are simply trusting that the wallet is implemented correctly=
, and in particular, that any creditor will not simply insert code in your =
open-source software to sign invalid transactions.
With a 1-of-1, any invalid-in-Sabu transaction can still be valid in the Bi=
tcoin blockchain layer, thus the scheme is simply insecure.
Features are meaningless without this kind of basic trust-minimization secu=
rity.
Regards,
ZmnSCPxj
