论文摘要
低吞吐量一直是大型区块链应用的最大障碍。在过去的几年中，研究人员提出了各种计划来改善系统的吞吐量。但是，由于互联网的固有效率低下和缺陷，尤其是在数据广播任务中，这些努力都变得不令人满意。在本文中，我们提出了一种新颖的区块链协议，该协议利用卫星广播网络而不是传统的互联网来进行数据广播和共识任务。还提出了一种自动恢复机制来解决卫星广播的独特通信问题。仿真结果表明，所提出的算法的通信成本较低，可以大大改善区块链系统的吞吐量。卫星广播启用区块链系统的理论估计为6,000,000 TP，具有20 Gbps卫星带宽。
Low throughput has been the biggest obstacle of large-scale blockchain applications. During the past few years, researchers have proposed various schemes to improve the systems' throughput. However, due to the inherent inefficiency and defects of the Internet, especially in data broadcasting tasks, these efforts all rendered unsatisfactory. In this paper, we propose a novel blockchain protocol which utilizes the satellite broadcasting network instead of the traditional Internet for data broadcasting and consensus tasks. An automatic resumption mechanism is also proposed to solve the unique communication problems of satellite broadcasting. Simulation results show that the proposed algorithm has a lower communication cost and can greatly improve the throughput of the blockchain system. Theoretical estimation of a satellite broadcasting enabled blockchain system's throughput is 6,000,000 TPS with a 20 gbps satellite bandwidth.
