Decentralized Privacy-Preserving Netting Protocol on Blockchain for Payment Systems

This paper proposes a decentralized netting protocol that guarantees the privacy of the participants. Namely, it leverages the blockchain and its security properties to relax the trust assumptions and get rid of trusted central parties. We prove the protocol to be optimal and we analyze its performance using a proof-of-concept implemented on top of Hyperledger Fabric.
