Mobile edge computing (MEC) is to process, analyse, store and calculate the network data at the edge of the network. When the ground infrastructure is damaged in an emergency, the unmanned aerial vehicle (UAV) formation can be rapidly deployed to undertake the task of MEC. However, there are some potential problems to be considered in UAV-enabled MEC, such as the trust among UAVs from different sources and the stability of UAV formation network. In view of the problems existing, this study proposes a blockchain-based architecture to build a system of mutual trust, fairness, openness, and stability in this scenario. Through the implementation of blockchain technology, key data such as device computing capacity, task allocation, and task execution process are recorded openly, transparently, and irrevocably. As multi-party trust is built to reduce the occurrence of fraud, system participants can get a reasonable reward. On this basis, the smart contract is used to ensure that algorithms are accessible to the public, and the sub-blockchain technology improves the stability of the system. In the case study, the simulation results show that the resource consumption and time cost of the proposed scheme is reasonable and feasible.

区块链：支持无人机的移动边缘计算的分布式解决方案

移动边缘计算（MEC）将在网络边缘处处理，分析，存储和计算网络数据。当地面基础设施在紧急情况下损坏时，可以迅速部署无人机（UAV）编队来承担MEC的任务。但是，在启用无人机的MEC中有一些潜在的问题需要考虑，例如来自不同来源的无人机之间的信任以及无人机形成网络的稳定性。鉴于存在的问题，本研究提出了一种基于区块链的架构，以在这种情况下构建相互信任，公平，开放和稳定的系统。通过区块链技术的实施，诸如设备计算能力，任务分配和任务执行过程之类的关键数据被公开，透明和不可撤销地记录。由于建立了多方信任来减少欺诈的发生，因此系统参与者可以获得合理的奖励。在此基础上，使用智能合约来确保算法可被公众使用，并且子区块链技术提高了系统的稳定性。仿真结果表明，该方案的资源消耗和时间成本是合理可行的。
