This summer, members of the Blockchain Technology Lab contributed to the Science and Technology Blockchain Conference (SBC) 2025, an international forum on the latest research in blockchain science and engineering. From the Lab, Aggelos Kiayias, Christina Ovezik, Yu Shen, and Lukas Aumayr were each involved in the programme, presenting and …
The Edinburgh Decentralisation Index (EDI) initiative continues to gain momentum. On September 17th, 2024, the EDI team held an in-person workshop hosted by the Scottish Government, bringing together representatives from the Bank of England, the Blockchain & Digital Trust Taskforce, and the British Blockchain Association. The session featured a presentation …
We are excited to announce the spin-out of the Edinburgh Decentralisation Index (EDI)—a major step in bringing decentralisation-based resilience assessment to security-critical domains beyond blockchain. The EDI project, developed at the University of Edinburgh, is at the forefront of measuring decentralisation in blockchain networks. Now, as a spin-out, we are …
Measuring Blockchain Decentralization with EDI The Edinburgh Decentralisation Index (EDI), developed by the Blockchain Technology Laboratory at the University of Edinburgh’s School of Informatics, is an initiative aimed at defining and measuring the decentralization of blockchain systems. By incorporating metrics from diverse fields such as economics and network science, EDI …
About EDI The Edinburgh Decentralisation Index is an initiative by the Blockchain Technology Lab at the University of Edinburgh to establish transparent, measurable decentralisation metrics for blockchain networks. Part of our mission is to reduce reliance on third-party data sources by independently gathering data through full-node setups. This approach enables …
The Edinburgh Decentralisation Index (EDI) project takes a deep dive into what decentralisation means in the context of blockchain systems. In earlier blog posts, we introduced the tool developed for the consensus layer and the dashboard that showcases some of our initial results, where more layers are gradually being added. …
We are thrilled to announce the next step in the evolution of the Edinburgh Decentralisation Index (EDI), a project dedicated to providing comprehensive insights into the decentralisation of various blockchains. Our platform is built on transparency and collaboration, and as we continue to develop, we’re inviting contributions from the broader …
The EDI team is officially launching today the alpha version of the index. The EDI is not a number or a graph! It is a framework, set of tools and graphical interface for the blockchain community to collaboratively and transparently measure and compare the decentralisation of different blockchain systems. Ultimately, …
The Edinburgh Decentralisation Index (EDI) project aims to define and measure blockchain decentralisation in a systematic way. As a first step, the EDI team identified 8 dimensions of blockchain systems that can exhibit different degrees of (de)centralisation and are therefore interesting to evaluate. These layers include : 1) Hardware, 2) …
In a previous blog post, we analysed Pool Splitting Behaviour and Equilibrium Properties in Cardano’s Rewards Scheme, demonstrating results from experiments that were carried out using a simulation engine that we developed. This time, we are here to explain in detail how this tool works and go over the design …
