What is a DAO and why does it matter to AEC?

Introduction Blockchain technology has revolutionized many industries worldwide, and the Architecture, Engineering, and Construction (AEC) industry is no exception. A significant innovation in this context is the DAO, which is a "Decentralized Autonomous Organization". A DAO is a blockchain-based organizational structure that operates decentralised, enabling transparent and collaborative decision-making and facilitating participatory governance. In this article, we'll explore what exactly a DAO is and why it's relevant and important to the AEC industry. What is a DAO?
