Nomadic labs has an ongoing research relationship with INRIA (a French national technology research agency).
In the context of this relationship, Nomadic Labs commissioned a short report to explore what a privacy-preserving amendment procedure might look like on Tezos, authored by three experts in voting protocols and cryptography: Véronique Cortier, Pierrick Gaudry and Stéphane Glondu.
There is no plan to implement the contents of the report for now, but we welcome and encourage feedback on its findings: from regular Tezos users, and from research and industry experts.
The report is here and we encourage you to leave comments in this agora post. Thank you.
