Research Project

Blockchain Technology for Algorithmic Regulation and Compliance (BARAC)

The BARAC project defines feasibility guidelines to policy makers, industry and regulators by identifying problems and associated solutions with a bottom up approach, built through case studies and proof of concept platforms.

Research project


Current cryptocurrencies, starting with Bitcoin, build a decentralized blockchain-based transaction ledger, maintained through proofs-of-work that also serve to generate a monetary supply. Such decentralization has benefits, such as independence from national political control, but also significant limitations in terms of computational costs and scalability.

Research Project


Today’s Internet is becoming increasingly centralised, slowing innovation and challenging its potential to revolutionise society and the economy in a pluralistic manner. DECODE will develop practical alternatives through the creation, evaluation and demonstration of a distributed and open architecture for managing online identity, personal and other data, and collective governance in a citizen-friendly and privacy-aware fashion.

Research Project

EPSRC Glass Houses

In recent years, the trust that society places in opaque centralised mechanisms run by government, network operators, and financial institutions has been eroding, with various events illustrating that high integrity cannot be achieved merely through trust in one or a handful of parties. As a reaction to this erosion in trust, two alternative architectures have emerged: users have either flocked to systems that have no central point of trust; or they have increased pressure on central entities to provide more openness and visibility.
