Proof-of-Learning: A Blockchain Consensus Mechanism Based on Machine Learning Competitions
Felipe Bravo-Márquez, Steve Reeves, Martín Ugarte · 2019
This article presents WekaCoin, a peer-to-peer cryptocurrency based on a new distributed consensus protocol called Proof-of-Learning. Proof-of-learning achieves distributed consensus by ranking machine learning systems for a given task. The aim of this protocol is to alleviate the computational waste involved in hashing-based puzzles and to create a public distributed and verifiable database of state-of-the-art machine learning models and experiments.
