Abstract

Blockchain technology has revolutionized distributed ledger systems by offering superior security and transparency compared to traditional centralized systems. Despite its advantages, current blockchain systems face significant challenges such as network congestion, communication errors, and scalability issues, largely due to the limitations of blockchain peer-to-peer (P2P) protocols. These problems hinder the performance, reliability, and widespread adoption of blockchain technology. In this paper, we propose a Trust-Defined Network (TDN) framework designed to solve these challenges by reflecting the physical network information to the blockchain. This approach enables the precise diagnosis of existing blockchain P2P protocol limitations and facilitates the objective verification of new improvement measures. Our proposed framework supports various blockchain network environments, particularly Ethereum-based networks, and ensures enhanced network stability and performance. Through extensive simulations and real-world case studies in IoT-enabled blockchain applications, we demonstrate that TDN significantly reduces network congestion, improves transaction finality, and enhances the reliability of blockchain communication channels. These findings highlight the framework’s potential to optimize blockchain infrastructure, making it more robust for large-scale deployment and real-world applications.

信任定义网络：分布式账本系统的全景P2P框架

与传统的集中式系统相比，区块链技术通过提供更好的安全性和透明度，彻底改变了分布式账本系统。尽管有其优点，但目前的区块链系统面临着重大挑战，如网络拥塞、通信错误和可伸缩性问题，这主要是由于区块链点对点（P2P）协议的局限性。这些问题阻碍了区块链技术的性能、可靠性和广泛采用。在本文中，我们提出了一个旨在通过向区块链反映物理网络信息来解决这些挑战的信任定义网络（TDN）框架。该方法能够精确诊断现有b区块链P2P协议的局限性，并便于对新的改进措施进行客观验证。我们提出的框架支持各种区块链网络环境，特别是基于以太坊的网络，并确保增强的网络稳定性和性能。通过对支持物联网的区块链应用的广泛模拟和实际案例研究，我们证明了TDN显著减少了网络拥塞，提高了事务终局性，并增强了区块链通信通道的可靠性。这些发现突出了该框架优化区块链基础设施的潜力，使其更适合大规模部署和实际应用程序。

期刊介绍： Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms. Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
