This summer, members of the Blockchain Technology Lab contributed to the Science of Blockchain Conference (SBC 2025), presenting work on decentralisation, consensus, and protocol innovation. Professor Aggelos Kiayias delivered a keynote –“The Evolving Art of Consensus: Post-Blockchain Theory and Practice” – tracing the path from proof-of-work to proof-of-stake, introducing concepts such as economic security, and reflecting on the trajectory of the Ouroboros family. You can watch the keynote below. For more videos from Christina Ovezik, Yu Shen, and Lukas Aumayr, see our full blog post. This article was published on 2025-09-05
