I am looking to create a game on Algorand. Here is how I see it.
Participants can “redeem” prime numbers as NFTs. They can exchange it between each other freely, and I am planning to create a marketplace app where all prime numbers would be listed, and users could bid/ask on them.
The only problem I have is that there is no straightforward way to ensure NFTs uniqueness. It would be nice to have an extra parameter UniqueID that the user can set during NFT creation, and the network would enforce it.
I am thinking about how to work around that limitation, but nothing solid comes to my mind. Here are the weak ones:
I can create a backend endpoint that a user can call. The endpoint checks uniqueness in DB and then creates an asset and passes it to the user.
An obvious drawback is that it is centralised and could potentially censorship users.
It is all about the marketplace app. It could list just the ones that were created first. I don’t like it either. It requires to have DB that tracks all the NFTs. Plus, there is an edge case when you make 2 ASAs in a single block.
I was thinking about a trick with ManagerAddr that has to be set to a specific contract address that would allow any other user to destroy the ASA if it is not unique. This seems fun and would even potentially add more gamification to the app, which is good. The bad thing is that it is probably not possible to implement. There is no way to store all created ASAs in some hashmap or hashmap like entity in the blockchain.
I would appreciate any feedback. Thank you.
