TL;DR
This paper tackles the problem of fake news by proposing a blockchain-based architecture that ensures immutable, auditable persistence of verdicts. It follows the Hoffmeister prescriptive process to derive an architecture and evaluates two candidate blockchain platforms—Hyperledger Besu and Hyperledger Fabric—through a brief proof-of-concept and simulation. The study presents a DEFC prototype, demonstrates AI-assisted or manual fact-checking workflows, and discusses interoperability, real-time performance, privacy, and governance concerns. The work offers a practical blueprint for decentralized, blockchain-backed fake news management that can inform government and public-agency deployments, while outlining future enhancements around authentication, scalability, and cross-platform integration.
Abstract
Fake News are a contemporary phenomenon with potential devastating effects. For inquiry and auditability purposes, it is essential that the news, once classified as false, can be persisted in an immutable means so that interested parties can query it. Although Blockchain clearly satisfies the main requirements for Fake News Management Software Systems, the prescriptive architectural solutions for that domain that cohabit Blockchain with other technologies in a single proposal still need to be made available. This paper's main contribution is presenting a prescriptive architectural solution for blockchain-based fake news management software systems. The Hoffmeister process for software architecture design is systematically followed to culminate in a software solution for that domain. The implementation of two candidate architectures and a brief simulation-based evaluation show the feasibility of the solution to satisfy the functional and quality requirements.
