In sum, we strongly believe that it's beneficial to preserve our ASIC resistance. Therefore, we will perform an emergency hard fork to curb any potential threat from ASICs if needed. Furthermore, in order to maintain its goal of decentralization and to provide a deterrent for ASIC development and to protect against unknown or undetectable ASIC development, the Monero team proposes modifying the Cryptonight PoW hash every scheduled fork, twice a year. The modifications will be light, and should not change performance profiles much. The first change is now being tested, and will happen in the coming March fork. Finally, we will continue to research alternative Proof of Work functions that may provide better ASIC resistance than Cryptonight.
Patches will be available for the following software: zone117x's pool, Snipa's pool, Lucas Jones' CPU miner, wolf0's CPU miner, ccminer-cryptonight, sgminer-gm, xmr-stak, xmrig-nvidia, wolf-xmr-miner.
Have any such PoW functions been mentioned, does anyone know?
