Blockchain and other forms of Distributed Ledger Technology (DLT) provide an opportunity to integrate digital information, management, and contracts to increase trust and collaboration within the construction industry. DLT enables direct peer-to-peer transactions of value across a distributed network by providing an immutable and transparent record of these transactions. Furthermore, there is potential for business process optimization and automation on the transaction level through the use of smart contracts, which are code protocols deployed on supported DLT systems. However, DLT research in the construction industry remains at a theoretical level; there have been few implementation case studies to date. One potential reason for this is a knowledge gap between use-case ideas and the DLT technical system implementation. This paper aims to reduce this gap by (1) reviewing and categorizing proposed DLT use cases in construction literature, (2) providing an overview of DLT and its design options, (3) proposing an integrated framework to match DLT design options with desired characteristics of a use case, and (4) analysing the use cases using the new framework. Together, the use case categories and proposed decision framework can guide future implementers toward more connected and structured thinking between the technological properties of DLT and use cases in construction.

区块链和其他形式的分布式账本技术（DLT）提供了整合数字信息，管理和合同的机会，以增加建筑行业内的信任和协作。DLT通过提供这些交易的不可变和透明的记录，实现了跨分布式网络的直接对等价值交易。此外，通过使用智能合约（在支持的DLT系统上部署的代码协议），可以在交易级别进行业务流程优化和自动化。但是，建筑行业中DLT的研究仍处于理论水平。迄今为止，几乎没有实施案例研究。造成这种情况的一个潜在原因是用例想法与DLT技术系统实施之间的知识鸿沟。本文旨在通过（1）对建筑文献中提出的DLT用例进行回顾和分类，（2）提供DLT及其设计选项的概述，（3）提出一个集成框架以使DLT设计选项与所需特性相匹配的方法来缩小这种差距。用例，以及（4）使用新框架分析用例。用例类别和建议的决策框架一起可以指导未来的实施者在DLT的技术属性和构造中的用例之间建立更紧密联系的结构化思考。（4）使用新框架分析用例。用例类别和建议的决策框架一起可以指导未来的实施者在DLT的技术属性和构造中的用例之间建立更紧密联系的结构化思考。（4）使用新框架分析用例。用例类别和建议的决策框架一起可以指导未来的实施者在DLT的技术属性和构造中的用例之间建立更紧密联系的结构化思考。
