I think Cindicator was the best
Best by far: Datum
They already have hardware, working prototype, very active development, a whitelist, and KYC.
www.Datum.orgboth of them are good. I like datum more but datum dev team is not enough to handle a large project like this. They dont have any experience before for this work
I support your opinion on these projects, but the cindicator has already ended, but the datum is still going on
