This article covers a technique my team and I use to work on versioned datasets across organizations (team A works on features, team B) works on other features. It's been invaluable for us since we don't have a shared infrastructure, so we can always verify the latest version by storing the latest hash on-chain.

It could be useful in other ways where integrity or immutability is paramount, like versions of models, model weights, etc. No need to share access to a central key management server and everyone can validate it simply.
