Overview

Decentralization is a foundational promise of blockchain technology, yet its measurement remains ambiguous and inconsistent. This presentation introduces the Edinburgh Decentralization Index (EDI), a research initiative offering a data-driven framework to assess the decentralization of distributed ledgers from first principles. We will explore the critical challenges in quantifying decentralization and demonstrate how subtle methodological choices can significantly alter assessment outcomes. The session will break down the pipeline for analyzing blockchains across eight distinct layers, ranging from consensus mechanisms and network structure to software development practices and token economics. Additionally, the public EDI Dashboard will be introduced, an open tool for transparent and replicable analysis.

Crucially, the principles underpinning EDI offer a robust model for developing quantitative indices in other complex cybersecurity domains. We will demonstrate how these principles are now applied to assess resilience in software supply chains through Cairnlytics, an experimental initiative that isolates the EDI software layer to help identify vulnerabilities in wider digital ecosystems. We will discuss how this framework informs our contributions to the ASC X9 TR-53 Cybersecurity Variance Index (CVI) by providing a blueprint for practical, evidence-based measurement of risk and resilience across modern financial systems.
