The only way to make PoW truly useful (so even frontier labs can run inference on it), is to let the *miner itself* pick the input matrices. While this indeed comes with the drawback that useless miners can mine the network, the economic incentive to do so with Pearl’s (FP) protocol is zero: AI miners produce ¶PRL at ~0$ marginal cost, so garbage mining is inherently discouraged.. If you don’t believe it, let’s speak in a year and you’ll see ❤️
