我们介绍了Saguaro，一个专门为边缘计算网络设计的许可区块链系统。Saguaro利用边缘计算网络的分层结构，通过介绍几种技术来减少广域通信的开销。首先，Saguaro提出了基于协调器的乐观协议，以低延迟处理跨域事务，其中涉及域的最低公共祖先协调协议或检测不一致。其次，通过层次结构收集数据，使更高级别的域能够聚合其子域数据。最后，由移动边缘设备发起的事务处理不依赖于高级雾服务器和云服务器。我们在各种工作负载上的实验结果证明了Saguaro在支持一系列跨域和移动事务方面的可扩展性。
We present Saguaro, a permissioned blockchain system designed specifically for edge computing networks. Saguaro leverages the hierarchical structure of edge computing networks to reduce the overhead of wide-area communication by presenting several techniques. First, Saguaro proposes coordinator-based and optimistic protocols to process cross-domain transactions with low latency where the lowest common ancestor of the involved domains coordinates the protocol or detects inconsistency. Second, data are collected over hierarchy enabling higher-level domains to aggregate their sub-domain data. Finally, transactions initiated by mobile edge devices are processed without relying on high-level fog and cloud servers. Our experimental results across a wide range of workloads demonstrate the scalability of Saguaro in supporting a range of cross-domain and mobile transactions.
