Abstract
En 中文
• We address the privacy-preserving multi-token bartering on blockchain where the exchanges of resources and goods can be privately performed. • We propose a novel decentralized protocol (i.e. PMTBS) with zeroknowledge proof and smart contract. • We propose a novel token transfer mechanism where each user updates only own balance. • We analyse the protocol from the security and scalability perspectives including computational, communicational and storage overheads. • We perform an experimental study to measure the blockchain gas consumption and zero-knowledge proof generation/verification times.
