I think this would solve one of the other issues I raised about the green address idea .... you can have some kind of trust aggregator sign the transactions. Merchants like MtGox that send would create a transaction, export it, upload it to the trusted authority which can just check IP address or something to verify it's really coming from MtGox, then sign it and broadcast it. --0016e6de0454b897e304b00ddf83 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable
You know, just t= hinking out loud...

Green addresses could be implemented as a second signature in the
scriptSig.

I think this would solve one of = the other issues I raised about the green address idea .... you can have so= me kind of trust aggregator sign the transactions. Merchants like MtGox tha= t send would create a transaction, export it, upload it to the trusted auth= ority which can just check IP address or something to verify it's reall= y coming from MtGox, then sign it and broadcast it.
