Is that right? Yes. Now, can we solve this problem robustly with clever technology, as is done with UTXO fraud proofs? I can't see a way - can you? Gavin asked me to do a projection for what block sizes could be based on technology improving, and I think that analysis should consider carefully to what degree the current system's quite strong censorship resistance will be impacted. It's interesting to be talking about censorship of transactions, right as the support for implementing technical means to block SatoshiDice transactions is highest. If anything, I think Gregory Maxwell's findings he has posted on IRC showing roughly three quarters of transactions in blocks are SatoshiDice related shows how the current large number of validating nodes makes any effort at even discouraging unwanted traffic quite difficult. In other words, it's a strong sign the censorship resistance of Bitcoin works as intended. --=20 'peter'[:-1]@petertodd.org --nFreZHaLTZJo0R7j Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAlE43MsACgkQpEFN739thowEYwCeO7awugctLTbUPX1B2JimgY+e Yq0AnRk2KtVuzZboE2soeUilZ6/5d/c5 =hpLz -----END PGP SIGNATURE----- --nFreZHaLTZJo0R7j--
