Current incentive mechanisms for construction safety highly rely on intermediaries and massive paperwork, which lay a foundation for opportunistic behavior and poor performance in the long run. As a solution, this study introduces an automatic incentive mechanism that rewards contractors with Fungible Tokens (FTs) and Non-Fungible Tokens (NFTs). Visual data of construction sites is processed through a computer-vision module, which reports safety performance. These reports are evaluated in a network of smart contracts, using a decentralized oracle network (DON), and token-based rewards are determined and distributed accordingly. Users can redeem their FT rewards or NFTs through an interactive front-end portal. The proposed method is successfully implemented through a synthetic case study to prove its feasibility. The proposed decentralized application (Dapp) provides a transparent, traceable, and immutable incentive mechanism that improves trust among stakeholders, and can be used as a template and expanded to fields beyond construction safety.

现行的施工安全激励机制高度依赖中介机构和大量文书工作，这为长期的机会主义行为和不良绩效奠定了基础。作为解决方案，本研究引入了一种自动激励机制，用可替代代币 (FT) 和不可替代代币 (NFT) 奖励承包商。建筑工地的视觉数据通过计算机视觉模块处理，报告安全性能。这些报告在智能合约网络中使用去中心化预言机网络 (DON) 进行评估，并相应地确定和分配基于代币的奖励。用户可以通过交互式前端门户兑换他们的 FT 奖励或 NFT。通过综合案例研究成功实施了所提出的方法，以证明其可行性。
