This way, the change should be The largest output on testnet is a bit under 1MB, and encodes a certain well-known love song... In many circumstances(1) miners have an incentive to create larger blocks t= hat take their competitors longer to receive and validate, so protocol-level bl= ock limits need to take all these potential DoS vectors into account; serialized size is one of the most fundemental things that needs to be limited. > considered non-controversial.

As mentioned above, and explained in detail in my recent blog post(1), restrictions are needed to keep a level playing field between all miners. 1) https://petertodd.org/2016/block-publication-incentives-for-miners --=20 https://petertodd.org 'peter'[:-1]@petertodd.org --/WwmFnJnmDyWGHa4 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQEcBAEBCAAGBQJXqT4mAAoJEGOZARBE6K+yG+EH/1JLQK39wkwg68/UVji/LkAK lmaF9nGkpgEXHBpQNx0pFYMSWCZu380bmBCm/UmOoGOqXjpPszfzfhN+UypUPiAH tbVY8q4jQqtMO2jZMC30AVRdwsp9HjByxATk1sXgYbiCNCrfOQdSwtZaUxb4WP3+ hqte/ZY0cemgC1lgZCbFbnnwKVlizULpDNNsfBubtBlxQ0zsWpf00DDeo0x3L+NY sS2uVeIhNVV9oADy9d1HZeSi1xGbB4G2QuqIbEA3Kms5MVdtSOgOjHpK86NkAt9L WKupIIRw+RnyIhqWMbTAwOBQqQo6u4d1M+bYFsr/0Y24Br6/tT9k7ZgZYbqEbTI= =KweW -----END PGP SIGNATURE----- --/WwmFnJnmDyWGHa4--
