Mobile edge computing unloading service system based on block chain delay perception

The invention relates to a block chain-based delay sensing mobile edge computing unloading service system, which is characterized in that distribution of computing unloading tasks is executed through an intelligent contract in a block chain, and distributed verification of a computing unloading service return result returned to a client is carried out in cooperation with zero-knowledge proof; the credibility of a calculation unloading service return result is ensured under the condition that a trusted third party does not need to participate; Meanwhile, a mobile edge computing unloading task which is sensitive to joint computing unloading reliability and delay is optimized, so that the delay between a client and an edge server which provides computing unloading service is reduced, and the reliability of information transmission is improved. 本发明涉及一种基于区块链延迟感知移动边缘计算卸载服务系统，通过区块链中的智能合约执行计算卸载任务的分配并配合使用零知识证明对返回给客户的计算卸载服务返回结果的分布式验证，实现在不需要受信第三方参与的情况下确保计算卸载服务返回结果的可信；同时对联合计算卸载可靠性和延迟敏感的移动边缘计算卸载任务进行优化，降低客户与提供计算卸载服务的边缘服务器之
