Re: rpietila Wall Observer - the Quality TA Thread ;)

So I'll send 2 transaction, is this possible ?
input ( a1=5 XMR, a2=5XMR ) output( g1=2 XMR, a3= 8 XMR ) -> ring-sing with a1

Let's do one at at time. This one needs to be signed using both inputs. so

input ( a1=5 XMR, a2=5XMR ) output( g1=2 XMR, a3= 8 XMR ) -> ring-sing with a1 + ring-sign with a2

You can't spent a2 without a valid signature (ring or otherwise)

OK np, I have both private keys, so I'll sing(ring or otherwise). What will be content ? (what I'm signing)

Now you are getting into an area the details of which I'm still working to fully understand in the code. But you are signing at least some portion of the transaction you create to spend the outputs, if not all of it.
