It's not possible to create consensus rules enforcing anything about fees because it's trivial to pay miners out of band. For instance, you can pay transaction fees by including anyone-can-spend outputs in your transactions. The miner creating the block then simply adds a transaction at the end of their block collecting all the anyone-can-spend outputs. Equally, if you try to prohibit that - e.g. by preventing respending of funds in the same block - they can simply publish fee addresses and have people put individual outputs for those addresses in their transactions. (IIRC Eligius gave people the option to pay fees that way for awhile) --=20 'peter'[:-1]@petertodd.org 00000000000000000fa57b40dc86a61d35aaf9241c86f047ef6f4bab8f13dfb7 --BXVAT5kNtrzKuDFl Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQGrBAEBCACVBQJVT8TZXhSAAAAAABUAQGJsb2NraGFzaEBiaXRjb2luLm9yZzAw MDAwMDAwMDAwMDAwMDAwYmRmMTI0NTczZjVkMzk3NjRhN2IyYjkwNjkxY2M4OTRk ODIyNzhlYWRmZGNkNjAvFIAAAAAAFQARcGthLWFkZHJlc3NAZ251cGcub3JncGV0 ZUBwZXRlcnRvZC5vcmcACgkQJIFAPaXwkft0uwgAk6tFybcXvhAvYoAbIJxd9gA/ v4OqvIa4A3TiE0sv5rsB0ZDWT/5FW5agVucB9Kob4siLfbu3FFTzuCGZnH3wYUE6 0hDWwSxM15BQnJXCugkDeQjz8GALJAq+bWZCDVruuuJOlu+0p93u8Vz/okhKZuvZ HkYkqrZpXdE2ZNxM7KPduDXU4jZx5L9VmEdjZFfVujfK8mEBYDG3ZEUaltmHuUvj BEtOLBqk8hXQAwtMl1zoF4/XK/VWZs1zDNW+92Z9op/601bZk8zPJGJXH4jRY1bD 28pgFfry2DZuHGg+Np1U9dYHLDCCk0DscHbg+6s19swqdLS5Ap9uqxy8Prs2sA== =rVkL -----END PGP SIGNATURE----- --BXVAT5kNtrzKuDFl--
