Please note that this expression of interest to participate in the TrustChain Open Call #2 – User Privacy and Data Governance evaluation as an external expert is NOT binding and does NOT constitute any commitment to the TrustChain project.  

The selection of the evaluators to support TrustChain in the evaluation of the Open Call will be taken at a later stage, since it depends on the number of received proposals, their origin, the domain that they target as well as the origin of the potential evaluators, their affiliations, their expertise and the balance between various criteria (e.g. gender, background, affiliation type, age, expertise etc.). Furthermore, it is mandatory to frequently change experts that support in the evaluations of proposals.
