A Research On Computing Resource Sharing Strategy Based On Blockchain

Cloud computing has received extensive attention due to its powerful computing and storage capabilities,but the high latency brought by long-distance transmission has an adverse effect on the user experience.In this paper,mobile edge computing technology is introduced to take advantage of the natural geographical advantages of edge nodes.Through Integrating idle computing resources in a region into a distributed edge computing platform,which provides fast,efficient and instant response.In order to solve the problem of user identity security in a distributed environment,this paper introduces blockchain technology to achieve trusted transactions between users.Facing the ”cold start” and ”long-term return” generated during the consensus process,a bank lending mechanism is used to solve the problem of insufficient funds.In order to reduce the cost of task calculation as much as possible,the paper studies the distributed local computing-server offload problem,and expresses the problem as a non-cooperative game between users.The users choose the least cost calculation scheme through competition.In addition,the control nodes grasp the global realtime information of the network,which provides data support for the user's choice.In the task allocation process,considering the energy limitation of the user device,an energy-constrained greedy game method is designed.In the initial stage,each user uses the greedy strategy to select the current optimal decision,and finds the best decision through the game.The experimental results show that the game can eventually reach Nash equilibrium and the convergence rate reaches 100%;the minimum cost of the distributed computing game is reduced by 20.07%,and the number of iterations is reduced by 87.69%.In addition,a pricing strategy based on task service level and real-time resource demand was designed,and the revenue of the server network increased by70.74%.Finally,the control node contract,resource transaction contract and bank loan contract are designed on the Ethereum.The experimental results show that the financial cost on Ethereum is low and the scheme is practical.
