摘要

在区块链系统中，通过共识协议允许节点在运行时发生变化是增强区块链可扩展性和安全性的有效方法。然而，传统的成员变更方法存在一定的局限性，无法满足区块链网络规模不断扩大的需求。提出了一种基于拜占庭容错（BFT）共识的成员变更框架：DynaNet。与类似的成员变更方法相比，DynaNet可以使任意数量的成员加入和离开系统，只需一个共识轮，并提供巨大的灵活性：它可以与大多数同步BFT共识协议集成，赋予其成员变更能力。我们展示了它与HotStuff: D-HotStuff的集成，并证明了它的安全性和活动性。实验表明，D-HotStuff在时延和吞吐量方面都有较好的性能，其多节点变更模式更加实用。

DynaNet: A dynamic BFT consensus framework

In a blockchain system, allowing nodes to change during runtime through consensus protocols is an effective way to enhance the scalability and security of the blockchain. However, some limitations of the traditional membership change methods prevent them from meeting the continuously expanding scale of blockchain networks. The paper proposes a membership change framework based on byzantine fault tolerance (BFT) consensus: DynaNet. Compared to similar membership change methods, DynaNet can make any number of members join and leave the system with just one consensus round and offer tremendous flexibility: it can be integrated with most synchronous BFT consensus protocols, endowing it with membership change capabilities. We showcase its integration with HotStuff: D-HotStuff and prove its safety and liveness. The experiment shows that D-HotStuff performs well in latency and throughput, and its multi-node change mode is more practical.

期刊介绍： The Journal of Systems Architecture: Embedded Software Design (JSA) is a journal covering all design and architectural aspects related to embedded systems and software. It ranges from the microarchitecture level via the system software level up to the application-specific architecture level. Aspects such as real-time systems, operating systems, FPGA programming, programming languages, communications (limited to analysis and the software stack), mobile systems, parallel and distributed architectures as well as additional subjects in the computer and system architecture area will fall within the scope of this journal. Technology will not be a main focus, but its use and relevance to particular designs will be. Case studies are welcome but must contribute more than just a design for a particular piece of software. Design automation of such systems including methodologies, techniques and tools for their design as well as novel designs of software components fall within the scope of this journal. Novel applications that use embedded systems are also central in this journal. While hardware is not a part of this journal hardware/software co-design methods that consider interplay between software and hardware components with and emphasis on software are also relevant here.
