> A company created a dataset and updates it from time to time. I suppose update frequency doesn’t matter from the perspective of just conveying how it works, but it could be updated frequently. For instance, any time a paper is published, or if the customer provided a data stream, etc. > Ok. And what is the use case? What would be different if they did not publish the hashes on a blockchain? The idea of blockchain is “don’t trust, verify,” right? Imagine you’re a researcher and you’re using this company’s services. Having the hashes on-chain allows you to verify the integrity of the data over time. Having it on-chain removes attack vectors associated with e.g. a standard database. Similarly, all of Vectorspace’s tooling for various services benefit from the same assurances that the data is sound. So like I said initially: data provenance.
