This is what I have done in the past with the blockchain camera and has nothing to do with solving social issues. It recognizes the objects in the photo and adds those as attributes to the NFT's metadata. Attribute is an important element in PFP NFT collections. The rarity of the NFT is determined by the rarity of its attributes, and people enjoy it. I considered whether this could be done with photos. However, the following issues have not been resolved.

• Classify the photographed objects. For example, living things and buildings.
• Attribute combinations must not be duplicated within an NFT collection.
• I need to create a machine learning model. I've used multiple object recognition services, but I haven't found a model that I like.
