Blockchain technology is the solution

NFTs have popularized the creation of unique, authenticated and tamper-proof digital twins based on blockchain technologies.

Today blockchain technology is mature. Some chains like Tezos are particularly energy efficient and inexpensive in gas.

But access to these technologies is complex, almost reserved for a world of geeks. Moreover, you must deal with cryptocurrencies, and it could be impossible for a large majority of companies.

So, we built NanoTrust to fix that !

Our conviction is that the document certification must be done at the same time as the document generation.

NanoTrust is a universal generator of digital twins.
