[cord] Build NFT as a Pallet #10
Description
NFT or Non-Fungible Token is one of the usecases many consider useful on a block-chain network. Many networks implement it as a Smart-contract.
In CORD, as each business logic is implemented as a pallet, one can consider to implement NFT as a pallet.
While there are some NFT implementations available in Substrate eco-system (and/or other substrate based projects), we should make sure this is tied to DID and chain-space of CORD, thus making it acceptable in CORD based networks.
