Özet
Sustainability awareness stoked the need to trace green/sustainable materials throughout the building life cycle to minimize environmental impacts, optimize resource use, and meet the standards of environmentally responsible construction practices. Traditional material tracing systems harness centralized servers, posing security and transparency issues. Blockchain technologies enable alternatives for achieving decentralized systems, which can resolve the limitations of centralized ones. Few blockchain and smart contract frameworks are presented for supply chain management, yet scarce research focused on tracing green/sustainable materials. This study aims to present a decentralized green/sustainable material tracing system framework for building life cycle with blockchain and smart contract technologies.
