Supply chain integration remains an elusive goal for the construction and engineering industry. The high degree of fragmentation and the reliance on financial institutions has pushed the physical and financial supply chains apart. The paper demonstrates how blockchain-based crypto assets address this limitation when used for conditioning payments on the flow of products. The integration of flows is contrasted in today's supply chains and those using crypto assets for their payment settlement. The thesis is validated in two construction projects where a smart contract administered payments in crypto currencies and crypto tokens. The findings reveal that crypto assets can enhance both the granularity and the atomicity of the integration between the cash and product flows; the on- and off-chain realities can be directly linked in crypto asset-enabled supply chains. The paper concludes with a discussion of risks such as regulatory landscapes, security, and price volatility and offers potential solutions.

供应链集成对于建筑和工程行业仍然是一个遥不可及的目标。高度分散的状况和对金融机构的依赖使实体和金融供应链分开。该论文演示了基于区块链的加密资产在用于调节产品流支付时如何解决这一限制。在当今的供应链和使用加密资产进行支付结算的供应链中，流量的整合形成了鲜明的对比。该论文在两个建筑项目中得到了验证，其中一个智能合约管理着加密货币和加密代币的支付。研究结果表明，加密资产可以增强现金和产品流之间整合的粒度和原子性。链上和链下的现实可以直接链接到启用了加密资产的供应链中。本文最后讨论了监管环境，安全性和价格波动等风险，并提供了潜在的解决方案。
