Privacy-preserving Identity Management System (PIMS). It is a (fair) privacy-preserving ID management system with applications to (KYC/AML verification in) financial sectors and voluntary organisations. It is being built on the Ethereum blockchain. This is joint work with Prof. Aggelos Kiayias. I was given a budget of £75k, to assemble a team and build the system. My main role in this project includes (a) designing the crypto. protocols, (b) implementing the back-end smart contract, and (c) leading the front-end developer team. The paper will be released soon. The related software is released and can be found here.
ValuEd: A Decentralised Service Market. This project aims at providing a decentralised service market to students to improve students’ collaboration and experience. The first experiment has been conducted on about 200 undergraduate students who interact with the framework. My role in this project was to assemble and manage a team, design the system, develop secure backend (i.e. Ethereum smart contracts) and lead the front-end developers’ team. The current version of the software is available here.
