Microsoft is shutting down its Azure Blockchain Service

I used it to experiment - it was super easy to set up a consortium, use their API to upload smart contracts, and try stuff out. Easy UI for visualising stuff. Can't think of an actual use-case, really.. but for experimenting, it was handy.

What are the practical uses of private blockchains anyway?

Docusign[1] has been using blockchain for a while now because it solves technical problems for their use cases.

Did Docusign really have a problem that couldn't be solved by any other means of publishing the hash?

Ultimately the hash comes from Docusign, so I'm not sure I can think of the problem case where someone doesn't trust Docusign to self publish that hash but does trust a hash that Docusign publishes to the blockchain.

I'd argue a more popular blockchain than their in-house one would provide stronger proof.

For example, a Bitcoin one: https://www.proofofexistence.com/

it is about timestamping basically nothing else. basically that cannot sign something in the past. Though you can do the same with sequence number, and publicly publishing all signed hashes.
