Certificate Registry

Certificate Registries are smart contracts that allow users to issue ERC-1155/ERC-1888 type of NFTs. Multiple Issuers can connect to the same Registry and issue NFTs on it.

Only a single Issuer (smart contract or blockchain account) can issue NFTs with a specific topic. Each topic can have a separate agreed-upon NFT metadata structure upon issuance.
