Looking for a speaker for an academic seminar on blockchains and markets

Hello, here at the Bureau d’Economie Théorique et Appliquée of Nancy (NE France) we are starting the planning of seminars for next academic year, and we would be interested in having a speaker (normally a PhD student or a recent post-doc) working in the business or economic implementation of blockchain technologies. Theoretical works are fine, but where the theory concerns the business or economic dimensions, rather than the technical one.
We pay for travel and accommodation expenses; the seminar can be held in English or French.

Do you know someone that could be interested ?
