Proof of Useful Work: Blockchain Web Services
A 2022 technical whitepaper proposing Proof of Useful Work (PoUW) as an alternative to Bitcoin's proof-of-work, directing miners' computation toward paying clients' ML training jobs and scientific simulations instead of purposeless hash puzzles. A direct response to the energy waste criticism of PoW mining.
Proof of Learning (PoLe): Blockchain Consensus via Neural Network Training
Proof of Learning (PoLe) repurposes the computation wasted on Proof-of-Work consensus by directing it toward training neural networks, making blockchain nodes useful ML workers. The cheating-prevention mechanism (Secure Mapping Layer) is the interesting technical contribution — a linear layer baked into the network architecture that makes it costly to fake training progress.
