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

초록

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.
