Quote

Peter Todd, backed by Matt Corallo, has proposed hard-fork changes to the bitcoin network to make useless patent pending algorithmic improvements which give mining an Asicboost of 20%, leading to increased profits of some $30 million if used by one of the biggest mining pools.

...Sergio Demian Lerner, a renown bitcoin security expert who collaborated with Timo Hanke in creating Asicboost, argued that changing the protocol would send a strong message to the ecosystem that any ASIC optimization should be kept secret and further stated that if the patent license is non-exclusive then all can use the optimization.

Timo Hanke stated that there was no way to know who was currently using the optimization as manufacturers do not reveal such information. Therefore, the proposed hardfork guarantees two co-existing bitcoin blockchains as current asicboost hardware would have no choice, but to continue mining on the current chain as they cannot switch over to the majority chain.

The above proposal has caused some controversy for indicating a central planner mind-set as well as a seemingly openness to hardforking after a year of vigorously arguing against it
