Centralized Accounts

In order to distinguish ownership and use rights, the most concise way is to use the CEX model, users will have a central account and a lease account, respectively, to represent their own NFTs and can use NFTs. But at the same time, implementing such a mechanism is complicated. The first step is to implement both the buy and sell, and lease requirements in the code, and separate the two accounts. After the lease occurs, the benefits of the original holder shall disappear in real time. This is comparatively harder to achieve.
