Review types

Four ways. One promise.

Whether on the wall, on the packaging, at the trade fair stand or on the tablet at reception: every review is given on site, is signed and can be checked by anyone afterwards. The only difference is where and when.

What all four have in common

Every review is signed on submission — classically and quantum-resistantly — and then timestamped in the Bitcoin blockchain. Your visitors do not have to take that on trust: the check runs in their own browser, independently of us.

And all four make visible where a review came about. That is the real difference from portals where anyone can write from anywhere.

Start with one.

The Basic profile is free of charge and the wall QR code is included in it. Everything else follows when you need it.
