A Platform-Free Proof of Federated Learning Consensus Mechanism for Sustainable Blockchains. (arXiv:2208.12046v3 [cs.CR] UPDATED)

Proof of work (PoW), as the representative consensus protocol for blockchain,
consumes enormous amounts of computation and energy to determine bookkeeping
rights among miners but does not achieve any practical purposes. To address the
drawback of PoW, we propose a novel energy-recycling consensus mechanism named
platform-free proof of federated learning (PF-PoFL), which leverages the
computing power originally wasted in solving hard but meaningless PoW puzzles
to conduct practical federated learning (FL) tasks. Nevertheless, potential
security threats and efficiency concerns may …
