Possible non-validation data that can be usefully propagated: 1) Block headers. 2) *Confirmed* transactions linked to an aformentioned blockheader. 3) Proof-of-work/sacrifice limited P2P messages, for instance to co-ordinate trust-free-mixes or act as a communication channel for micropayment channels. 4) With UTXO existance proof support propagate transactions accompanied by proofs that all inputs exist. This would also allow for implementation of Peter's low-bandwidth decentralized P2Pool proposal. 5) UTXO fraud proofs. (one day) Strictly speaking #2 doesn't even need the protocol to be changed actually as it can be handled entirely within the existing INV/getdata mechanism. Sure someone could throw away a lot of hashing power and get an invalid block propagated, but really so what? SPV nodes should always take confirmations with a grain of salt anyway. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEcBAEBCAAGBQJRzWx8AAoJEEWCsU4mNhiPlTkIAJKzFsT65o6LoU70hbaBsu3g aBdjYZSCnJ9+qWI2tqqUBedq2etbt71hAfWNnTXvFus+0iVB1HWJClW155319vuH Xi1m9G3O0NzX1d+cssMPxFBHsl4Rz6XYICrYyVEe2X554Zawdg6I53+1INHRfsBT 1vmq5Bxgopt0Tk9Vf8HNdRt/IXZJaPYm1PEzJHFppuOvl5+Fpypy3t/QXdsP8puP LnRdL7Bxfu3BSWrSRZo7l5Fpww3Y/vdNYCL4jDD/ME+36wi4CUM3psL8lsk81lB4 3t/ytF4y/adT/dEEtMj7BGWS0TIMMH0NyeCjqBdStiQsVfoowLCVfpuDzouZ6yY= =TI1m -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Bitcoin-development mailing list Bitcoin-development@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bitcoin-development
