Blockchain-Enabled Peer-to-Peer Data Trading Mechanism

The emerging data-driven techniques have greatly increased the demand for effective data sharing infrastructure, which is our fundamental motivation in designing effective data trade paradigms. One of the critical challenges of data sharing is to achieve a good trade-off between the privacy and data utility. To address this challenge, in this paper we exploit the Blockchain techniques and contract theory to design a Blockchain-based peer-to-peer data trading mechanism. In our proposed mechanism, the data trading is supported by Ethereum Blockhain technique. To effectively capture and regulate the complex interaction between the data aggregators (AGG) and the data owners, we propose a contract theoretic approach to design the smart contract that is the essential component of Ethereum Blockchain. The performance of our proposed Blockchain-enabled data trading mechanism is evaluated.
