[Feature Request]: Dual role NFT

[pause125]

Feature Request

Describe the Feature Request

Ethereum passed ERC-4907 standard in which a NFT has two roles: owner and user.

There may be an owner of the NFT that rents it out to a “user”. The actions that a “user” should be able to take with an NFT would be different from the “owner” (for instance, “users” usually shouldn’t be able to sell ownership of the NFT). In these situations, it makes sense to have separate roles that identify whether an address represents an “owner” or a “user” and manage permissions to perform actions accordingly.

I think this is a very useful feature to make NFT having more use case.

In ERC-4907, the user can not invoke the transfer function, and only the owner can.

All DApp need to use userOf to replace ownerOf to support the rent cases.

There is an option: each NFT has a use_capability which is a standalone resource, and can be transfered. Dapps can check the use_capability.
