馃帹 dada.nyc is an inspiring site I recently visited. Though I still can't figure how digital images is protected by Ethereum blockchain and it's limited copies, I can find a great potential if this is true.
Below are some samples that you can buy through their website which is built as a conversation using drawings. As I can share it below how they are limited in anyone collection as the website claims. I would like an explanation as I'm really super interested in the concept and would like to try it myself by sharing some of my drawings.
