About

The Blockie Doggy is a demo project created during Truffle Univerity. The project shows how ERC721 token can be used to create a simple decentralized animal registry.

ERC721 token used as a base for animal identity. I created additional extension 'ERC721Claims' that makes it possible to add 'claims' to the animal identity. 'Claims' are proved by veterinary information about a dog. For example dog's special ability. Take a look at 'ERC721ClaimsInterface' contract to see the basic structure of this extension.

Use Cases

• The animal owner can register the dog and get ERC721 token as a dog ID.

• Veterinary can add 'claims' to a dog ID. Such as information about vaccination or special dog's abilities.

• Anyone can check information about a dog. See the ID and issued 'claims'.
