What file storage solution is Cardano invisioning to use? IPFS?
If you mean for the blockchain, it’s a long time since I studied comp sci but my gut feeling is, this is not a good idea. For anything so highly distributed to be spread across decentralized storage would be a very complicated arrangement and I’d guess pretty inefficient. For off-chain data storage, on the other hand, using some kind of reference/pointer on the chain, IPFS might work well, I’d guess.
