基于区块链的信任评估模型研究

TRUST EVALUATION MODEL BASED ON BLOCKCHAIN Zhang Xuhao Feng Wenlong

传统的分布式信任评估模型由于不可信的网络环境,导致模型参考的评价信息来源以及内容不可信,最终使得评估模型不准确。区块链具有公开透明、防篡改、可溯源等特性,将区块链与信任评估模型结合,可以提高分布式网络中信任评估模型准确度,从而解决信任问题。介绍主流的基于区块链信任评估模型,研究这些模型的算法思想和解决的问题;总结这些模型的优缺点以及应用场景;对基于区块链的信任评估模型的研究方向做探讨。

The traditional distributed trust evaluation model is not accurate because of the untrusted network environment,which leads to the unreliable information source and content of the model reference.Blockchain has the characteristics of openness,transparency,tamper resistance and traceability.The combination of blockchain and trust evaluation model can improve the accuracy of trust evaluation model in distributed network,so as to solve the trust problem.This paper introduced the mainstream trust evaluation model based on blockchain,studied the algorithm idea of the model,analyzed the application scenarios and the problems to be solved,pointed out the advantages and disadvantages of each model,and summarized the shortcomings of the existing trust evaluation models in blockchain and the possible research directions in the future.
