【Improved PBFT Consensus Algorithm Based on Node Role Division】
#论文# #区块链# #共识算法# #节点#

One of the key components of the blockchain system is the consensus algorithm, which is essential to the effectiveness, security, and stability of blockchain data processing. Different consensus algorithms are required to enable blockchain systems under various application scenarios. This paper presents modified PBFT (Practical Byzantine Fault Tolerance) consensus algorithm based on role division as a solution to the issue of choosing a trustworthy master node when there are many nodes.

Asymptotic is the land of no limits. In asymptotic, performance metrics are evaluated under assumptions of large or small parameters. In fact, capacity expressions available for the single-link and for other settings are the result of coding theorems that already benefit, as mentioned earlier, from an infinite block-length. Other common PHY parameters explored in asymptotic include the SNR, the number of antennas, and the number of users.

【北京市民通过MaaS系统可以获得这些便利】说到绿色出行，北京市于2019年推出国内首个绿色出行一体化服务平台（MaaS），北京市交通委员会二级巡视员、宣传处处长 何益海做客北京交通广播《交通大家谈》节目时介绍：MaaS（Mobility as a Service，出行即服务）是近年来全球交通领域出现的新理念，其核心是从拥有车辆转变为拥有交通服务，通过一体化交通出行和一站式服务，改善市民公共出行体验，目前已成为全球各大城市重点关注和共同追求的国际趋势。北京MaaS平台整合了公交、地铁、市郊铁路、步行、骑行、网约车、航空、铁路、长途大巴、自驾等全品类的交通出行服务，能够为市民提供全流程、一站式“门到门”的出行全过程规划服务。2020年9月，对MaaS平台进行升级，联合高德地图、百度地图启动“MaaS出行 绿动全城”行动，主要是基于MaaS平台推出绿色出行碳普惠激励措施。#1039交通大家谈#
