That's a really old idea - I proposed it about two years ago. The optimal way is to allow any txout to be replaced with one with an equal or greater nValue and same scriptPubKey, as well as additional txouts added. (obviously so long as none are removed) Alas, there's lots of situations where this restricts you from doing useful things, for instance collapsing multiple payments into one by repeated updating to reduce tx size. Equally the benefit is marginal at best given how insecure unconfirmed transactions are - breaking what is already broken isn't a negative. -----BEGIN PGP SIGNATURE----- iQE9BAEBCAAnIBxQZXRlciBUb2RkIDxwZXRlQHBldGVydG9kZC5vcmc+BQJU6d9O AAoJEMCF8hzn9LncUOUH/3yY4wDyFSkL9o6GsntphAmJSN35wVAlxPxBmNTk0KR3 YfVhY1cTBIXKqsfqz/n1Sqn264aMzW48xUTtDF2xLzJc1FY5qTBw7zbVrZgYIvvr GEakZW1SxLXsfSs2Onutl0WQWi8EMfxEXEPQIiiWy9mq4EtwxMOcDviETycu6Wmn pmHY00Lo8jhLUyuIkzIZrZetEtWz1VtovbJO5l7WfmLgPWzW+zERPY/pGGioqdiJ NOEaocQ+2+OZjyx3MJ4YAch5ZtfB45g+NBm8WyeGpBgxzK3ZIpmyZIQ6HqZr0gpl NMUQh6Sbi8WaTEp6hoYTiEfZcEy4IDPg6f0DEW71BPs= =1vbN -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
