SPDL: Blockchain-secured and Privacy-preserving Decentralized Learning. (arXiv:2201.01989v1 [cs.CR])

Decentralized learning involves training machine learning models over remote
mobile devices, edge servers, or cloud servers while keeping data localized.
Even though many studies have shown the feasibility of preserving privacy,
enhancing training performance or introducing Byzantine resilience, but none of
them simultaneously considers all of them. Therefore we face the following
problem: \textit{how can we efficiently coordinate the decentralized learning
process while simultaneously maintaining learning security and data privacy?}
To address this issue, in this paper we propose SPDL, …
