2D barcode hash based UPC codes for everybody

* You upload a piece of content to a Server

* the Server hashes the content (you could be a Server.)

* it creates a 2D bar code of that hash, with a URL redirection pointer

* you print the hash and stick it to things

* anybody who wants to know what it is takes a picture, and checks the hash against a distributed database of hashes, much like DNS

* typically a hash would be a URL, email address, or other short string

* very short content can be encoded directly, without the hash, of course - but at that point, why not just print the string on it.

Like Thinglink, but with sensible crypto features.

    Mmn. I’m not sure I understand the added benefit from standard QR-code (with an online or offline QR-code generator), apart from the fact that it forces you to rely on a 3rd party server… Unless anonymization is what you are after, maybe?
