>But being able to do much more efficient blockchain validation at a much lower cost, much lower power, is a pretty solvable problem. Mining ASICs don't do anything like blockchain validation; they instead solve a hash partial preimage problem, mostly after blockchain validation has been done on CPUs (although when a new block is published and its PoW verified, a miner might try solve the puzzle on top of the new block before it has had time to validate that block, betting that the new block is very likely to be valid).
