The only application i can think of is proving something existed at a certain date by putting the hash in the blockchain.
Op says it won't help authorship since earlier real author can claim he didn't use the blockchain but it's still helpful to prove something simply existed.
- lawn 8y agoFor example: You find a security vulnerability in some applications. You want to make an anonymous disclosure but you want to be able to prove you knew about it at a certain time. So you create the message "I John Doe has found the vulnerability ..." and add the hash to the blockchain. You can now definitely prove that you knew about it and had documented it at a certain timestamp before the disclosure.
