Abstract

The Architecture, Engineering, and Construction (AEC) industry has experienced an unprecedented surge in data growth, primarily propelled by the widespread adoption of digitalization technologies, including Digital Twins (DTs). This surge poses challenges in terms of data control and ownership. To address this, this paper presents a decentralized platform using blockchain-enabled dynamic Non-Fungible Tokens (NFTs) to securely represent DTs. The framework, implemented as a decentralized application (dApp), utilizes a Decentralized Oracle Network (DON) and interconnected smart contracts to convert DT data into dynamic NFTs for a public marketplace. Demonstrated through a synthetic case study, the framework offers transparency, traceability, and immutability. It introduces sustainability-related implications, such as a building carbon credit market, and financial implications, like trading AEC knowledge and a proposed project financing method. This model ensures DT ownership in AEC but also builds trust for knowledge exchange, potentially serving as a foundational model for applications beyond the AEC industry.

数字孪生不可篡改令牌(DT-NFT):实现 AEC 行业的数据所有权
建筑、工程和施工(AEC)行业经历了前所未有的数据激增,主要原因是数字化技术(包括数字孪生(DT))的广泛应用。这种激增给数据控制和所有权带来了挑战。为了解决这个问题,本文提出了一个去中心化平台,使用区块链支持的动态不可篡改代币(NFT)来安全地表示 DT。该框架以去中心化应用程序(dApp)的形式实施,利用去中心化 Oracle 网络(DON)和互联智能合约将 DT 数据转换为公共市场的动态 NFT。该框架通过一个合成案例研究进行演示,提供了透明度、可追溯性和不变性。它引入了与可持续发展相关的影响(如建筑碳信用市场)和金融影响(如 AEC 知识交易和拟议的项目融资方法)。该模型确保了 DT 在 AEC 中的所有权,同时也为知识交流建立了信任,有可能成为 AEC 行业以外应用的基础模型。
