I´m starting with the course "Blockchain for Business Sustainability" (the subject is awesome).

1. Blockchain’s Role in Sustainable Business Practices.

Years ago I saw on TV that in Japan (the future in many things) you could know who was the producer of a food before buying. Not only in processed food.

You could know who is the person who grew, for example, fruits and even a photo of the place where the tree is or was. I call it "Precision Era" which is our next, post-"Information Era".

In this first chapter we find some examples of companies in ETH or Solana that are developing precision and combating fraud.

It is not yet, but an organic food certificate is predicted.
