Trust-Defined Network: A panoramic P2P framework for distributed ledger systems
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.
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.
