Distributed Ledger Architecture for Collaborative Megaproject Management with Authenticated Participants

Abstract

Distributed Ledger Technology can benefit the severe and chronic issues in the planning and execution of complex projects. However, while the general potential is recognized, there is little rigorous discussion of the pathway to benefits or detailed description of architectures to realize them. Here, we start by discussing the severity and causes of the problem. We then present an architecture designed to ameliorate them. Project networks are temporally constrained DAGs; new value is created at project milestones corresponding to the DAG vertices. Building on these characteristics, we describe an architecture for collaborative planning and execution with smart contracts at milestones and tokens backed by project created assets.
