It is a very interesting fact that the blockchain and cryptocurrency technologies have even reached the sphere of photography. This is definitely a positive trend, I am very pleased.
You are right, this is undoubtedly a very positive phenomenon, but the technology of the blockchain and cryptocurrency came a relatively long time ago in sphere photografy, about a year ago there were similar projects.
I surely would like to know the names of these project. It's either
1. That I haven't heard of them before or
2. They have failed what they started. This is something we as a project can learn from so I am really looking forward hearing from you the names of these projects
