A Distributed Peer-To-Peer Framework for Online Services: Protocol Design and Validation

Abstract

The rapid growth of digital services has made it essential to have secure, transparent, and decentralized platforms to support reliable and efficient service exchanges in recent time. This study presents a distributed blockchain-based framework that facilitates trustworthy and reputation-driven interactions between service providers and receivers. Service providers can register and promote their services, while users can browse, search, and request offerings through a decentralized and transparent network in this system. Each transaction is immutably recorded on a blockchain ledger, ensuring tamper-proof documentation of service details, including transaction ID, participants, status, timestamp, and review content. The platform also uses a dynamic reputation system where user feedback generates a score that influences future service interactions for both the service provider and the receiver. A proof-of-concept prototype was developed and evaluated to demonstrate the feasibility of integrating this blockchain-based distributed peer-to-peer system into serviceoriented digital platforms. The experimental results validate the system's capacity to handle diverse transaction types while maintaining performance, scalability, and user satisfaction. This approach improves accountability, fosters trust, and mitigates fraud in peer-to-peer digital marketplaces.
