Am a Blockstack newbee doing a feasibility study if blockstack would be useful for my use case.
I wanted something that can save unique usernames and public key on the blockchain. Then I wanted from the app to query the blockchain for the public key of a certain user and use it to verify that data on IPFS was created by the actual author and not by someone pretending to be the user.
Then I wanted to create a download manager that could download the data to the local machine and notify when the download had completed.
Does that look like a use case for a blockstack app?
Thank you for anyone who can answer my question
