Useful proof of work verification problem, AI training and protein folding claims

April 5, 2026r/CryptoCurrency

In r/CryptoCurrency, the community debates whether useful proof of work is real innovation or marketing, centering on the hard part: cheap, trustless verification of off chain work like AI training or protein folding.

I keep seeing projects say their mining does AI training or protein folding or whatever instead of just securing the network.
in most cases it’s more marketing than a real shift, because traditional PoW is designed to be trivially verifiable while things like AI training or protein folding are hard to verify cheaply
A big criticism of PoW is that it takes huge amounts of energy to do pointless cryptographic work. Any PoW system that does useful work is better.
