**A propos du centre ou de la direction fonctionnelle**:
The Inria Rennes - Bretagne Atlantique Centre is one of Inria's eight centres and has more than thirty research teams. The Inria Center is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc.

**Contexte et atouts du poste**:
In this context, we are proposing a novel algorithm for asset transfer (cryptocurrency) that has three noteworthy properties, namely consensus-freedom, cost-effectiveness, and quasi-anonymity. Consensus-freedom means the system does not rely on a total order on asset transfers. Cost-effectiveness means that processes only need to store their own asset transfers and some short, constant-size control data. Quasi-anonymity means that no information is leaked on the asset transfers’ receivers and amounts, and that the asset transfers’ senders can be obfuscated with high probability. As far as we know, it is the first asset transfer system that satisfies all these properties at once. To obtain them the article considers new distributed objects such as agreement proofs as well as well-known techniques such as commitment objects, zero-knowledge proofs, and cryptographic accumulators.

**Mission confiée**:
This engineering position involves implementing the aforementioned asset transfer solutoin. In this task the engineer will be guided by the team who have been working on the algorithm design. The engineer will also have the opportunity to collaborate with other partners from the PriCLeSS and SOTERIA projects.

**Principales activités**:
The engineer will follow the following approximate timeline.
- M1: Analysis of the state of the art:

- Analysis of existing Money Transfer implementations.
- Research papers on Money Transfer including the one on the proposed algorithm
- M2: High-level design of the implementation.
- M4: Zero Knowledge-Proof Implementation
- M6: Complete algorithm implementation
- M8: First version of the interface around the algorithm
- M12: Final release of the Money Transfer system.

**Sécurité défense**:
Ce poste est susceptible d’être affecté dans une zone à régime restrictif (ZRR), telle que définie dans le décret n°2011-1425 relatif à la protection du potentiel scientifique et technique de la nation (PPST). L’autorisation d’accès à une zone est délivrée par le chef d’établissement, après avis ministériel favorable, tel que défini dans l’arrêté du 03 juillet 2012, relatif à la PPST. Un avis ministériel défavorable pour un poste affecté dans une ZRR aurait pour conséquence l’annulation du recrutement.

**Politique de recrutement**:
Dans le cadre de sa politique diversité, tous les postes Inria sont accessibles aux personnes en situation de handicap.
