摘要
随着基于智能合约的云网资源交易技术的发展,算力交易向多方规模的形式发展,严重影响算网资源的高效可信交易。针对算力网络资源多方参与场景下的可信交易与高效资源激励需求,设计基于区块链的算网资源可信身份认证与资源交易激励机制。该机制采用基于算网用户身份信息可靠度的分布式认证策略,通过公证机构授权构建可信交易委托证书,实现资源交易任务可信进行。讨论基于契约理论的交易激励机制在算网资源可信交易与高效性服务上的应用,并与线性激励、信托激励模型进行机制对比,对算网参与方的资源效用收益与社会福利进行比较,进行多方最优效用收益激励验证,衡量本机制的激励效率。证明资源交易激励机制在交易验证场景的有效性,有效保证算网资源在多服务方接入的可信交易与高效激励。实验结果显示,该交易机制能够保障多方算网用户交易的可信性、可验证性与稳定性。所提机制在资源交易效率与社会福利收益方面均优于传统交易激励机制。
With the development of cloud-network resource transaction technology based on smart contracts,computing power transactions have reached a multi-party scale,seriously affecting the efficiency and credibility of computing network resource transactions.To meet the requirements of trusted transactions and efficient resource incentives in the scenario of multi-party participation in computing network resources,a blockchain-based trusted identity authentication and resource transaction incentive mechanism for computing network resources was designed.The mechanism adopted a distributed authentication strategy based on the reliability of user identity information of the computing network and constructed a trusted transaction entrustment certificate through the authorization of an impartial agency,realizing the trusted implementation of resource transaction tasks.In addition,the application of the transaction incentive mechanism based on contract theory in the trusted transaction and efficient service of computing network resources was discussed.The mechanism was compared with linear incentive and trust incentive models,and the resource utility income and social welfare of the computing network participants were compared.The multi-party optimal utility benefit incentive was verified to measure the incentive efficiency of the mechanism.It proved the effectiveness of the resource transaction incentive mechanism in the transaction verification scenario and effectively ensured the trusted transaction and efficient incentive of computing network resources accessed by multiple service parties.Experimental results show that the proposed transaction mechanism could ensure the credibility,verifiability,and stability of multi-party computing network user transactions.The proposed mechanism is superior to the traditional transaction incentive mechanism in terms of resource transaction efficiency and social welfare benefits.
