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.
There were no projects with such a concept, they were similar, but they didn't take their chances at all and didn't realize their potential. I like the OCUL project more than others same projects.
