ePrint Report: Provably Secure Blockchain Protocols from Distributed Proof-of-Deep-Learning

Xiangyu Su, Mario Larangeira, Keisuke Tanaka

Proof-of-useful-work (PoUW), an alternative to the widely used proof-of-work (PoW), aims to re-purpose the network's computing power. Namely, users evaluate meaningful computational problems, e.g., solving optimization problems, instead of computing numerous hash function values as in PoW. A recent approach utilizes the training process of deep learning as ``useful work''. However, these works lack security analysis when deploying them with blockchain-based protocols, let alone the …
