Leveraging Blockchain Technology to Enhance Transparency and Security in Engineering Project Bidding Systems

Abstract

With the intensifying competition brought by economic globalization, the efficiency, fairness, and integrity of engineering project bidding systems have become critical factors influencing industry dynamics. Although electronic bidding platforms offer advantages such as enhanced transparency and reduced costs, they still face significant challenges, including fraud, illegal operations, information leakage, and limited data sharing. Blockchain technology, characterized by decentralization, immutability, transparency, and smart contracts, offers a promising solution to these issues. This study reviews the current state of engineering project bidding systems and analyzes how blockchain can address existing problems by enabling traceability, secure data sharing, and automated contract enforcement. Drawing on recent research, it proposes a blockchain-based bidding model that improves information reliability, ensures full-process supervision, and fosters trust among stakeholders. The findings suggest that integrating blockchain technology into bidding processes can fundamentally reshape project procurement practices, enhance governance, and promote the sustainable development of the engineering industry.
