There appear to be 2 two substrate forks addressing offchain data storage with a IPFS backend:
- https://github.com/iridium-labs/substrate/tree/iris
- https://github.com/WunderbarNetwork/substrate/tree/ipfs-ocw
As best I can tell (very new here so could be wrong) they take 2 different approaches: Pallet vs chain extension.
- What are the relative merits of each approach to implementing IPFS: pallet vs extension chain?
- Which is more likely to land upstream?
- Is it possible to track/estimate the time frame in which these might land upstream?
This is not the question: what are the ways to store offchain data
> These solutions will not land into core substrate repo.
New here... are you a member of the core team?
