Distributed Data Trading Model Based on Blockchain

Abstract

The current flow and trading of data has been a trend, but the current enthusiasm for data trading is not high. Due to the particularity of data and the current trading pattern of data, the ability of data trading platform to retain trading data has become a potential threat to both sides of the transaction and an obstacle to data trading. Due to the sensitivity of data, how to protect the privacy security of both sides of the transaction is also an important factor hindering the current data transaction. In response to the existing problems, this paper proposes a feasibility plan for data security transactions based on blockchain and in an untrusted environment, and designs a new decentralized transaction platform that will help transform data through online transactions. At the same time, it is technically guaranteed that the platform does not have the possibility of viewing, copying and detaining data, thereby ensuring the secure transaction of data and the privacy of both parties to the transaction.
