Announcement: We will withdraw support from February 21s roundtable consensus, unless Adam Back gives us a reasonable explanation why he quietly changed his title from Blockstream President to Individual at the very last moment without anybody noticed. We feel weve been cheated. I dont know how we can trust Blockstream anymore in the future.
SHA3 is looking better everyday we have to watch the ASIC miner tail struggle to wag the Bitcoin dog.
Resetting to SHA3 just weakens bitcoin hashing power temporarily and then maybe permanently. I say permanently since miners may discount their profits by taking into the possibility that the greater bitcoin community will make their investments worth zero at any time.
While a PoW hash reset could be used in the event of a mining attack, don't kid yourself - no one is seriously pushing for a beyond-controversial PoW change at this time.
