摘要
在传统数据库平台的基础上,提出了一种基于新的评价机制和以太坊平台实现的区块链存储技术。该技术结合智能合约技术进行上链前数据的筛选实验,保证链上数据的有效性和真实性;采用了哈希存证进行数据上链,确保分享数据的可信性;并结合了区块链本身的特性使数据难以被篡改。实验表明,与传统数据库相比,根据计算的用户可信赖值T,这种区块链评价机制存储模型能够有效过滤80%以上的恶意评论。
A blockchain storage technology on account of a new evaluation mechanism and ethereum platform implementation is proposed based on the foundation of traditional database platform. The technology combines smart contract technology to screen the data before on-chain to ensure the validity and authenticity of on-chain data;Hash deposit is adapted to ensure the credibility of shared data;And the nature of blockchain itself is combined to make data tamper hardly. The experiment shows that compared with traditional database,the storage model of this blockchain evaluation mechanism can effectively filter more than 80% of malicious comments according to the calculated user trust value T.
