Summary
This paper introduces MSDT, a blockchain-based data trading protocol that guarantees trading atomicity and data quality without a trusted third party. It uses a state channel-based trading contract to reduce on-chain costs and a staking mechanism with a trading strategy to deal with malicious data owners. The authors report that security and performance analyses show MSDT ensures atomicity and data quality verification while keeping efficiency comparable to existing solutions.
