Hey there, i thought i provide some feedback that might help direct your exploration.
There are various projects working on the various concepts you mentioned, i recommend referencing a few more of them ( especially related to NFTs and Subscriptions), because it will shows you have an understanding of what projects are going on in the ecosystem; and then you can perhaps see what they are working on and show how what you are working on complements it, or is different in some way, which will bolster your case.
I’m actually very interested in the subscriptions aspect of this post. On-chain Subscriptions and automations will bring real revenue models and create sustainable businesses that have users.
- Lay the foundation for a new NFT vertical that can be used to disrupt the web2 subscription space
Having an NFT that you are provided on the basis that you make regular payments is interesting. Though just on-chain payment automation is powerful enough in itself (to disrupt web2 subscriptions)
- Currently, in order to implement subscriptions we would need to rely on token allowances and streaming escrow contracts. This approach is very complex, fragile, and hard to use. By creating a standardized subscriptions pallet we can simplify the usage/creation of subscriptions and bring completely new users and businesses into Polkadot
Let me point your attention to Oak who have done some very strong work. Check out 2 of their pallets that deal with price and time triggers, and you can vary the frequency of recurring payment collections. Such as monthly payment subscriptions for NFTs.
IMO, you may not need to build another subscriptions pallet if you have not started to already, you can leverage Turing parachain (OAKs parachain on Kusama) and create a cross chain DApp that harnesses NFTs from AssetHub and on-chain subscriptions with Oak.
We have the opportunity to leverage the cross-chain infrastructure abstraction layer, where you can cherry pick what pallets you need from different chains and then build user experiences around that. Which may free you from the burden of building pallets and the UIs to match.
If you want to build pallets for Asset Hub you wouuld need to start the conversations with the fellowship who decide what to deploy on system chains.
