Show HN: Free legally-valid timestamps for your intellectual property

Hey all,

I’d like to share a decentralized app I built a couple days ago as part of the #24hrstartup challenge on Product Hunt + Twitch.

Claimby helps you protect your intellectual property by creating a blockchain timestamped proof of existence for any file or piece of text. Basically, it generates a unique SHA-3 hash of your file & writes it to the Ethereum blockchain. While it isn't the same as filing a patent or copyright, it is still proof that you possessed that file or idea at that exact moment in time. This can be useful evidence in any type of intellectual property ownership dispute. As of recently, China and many U.S. states (Arizona, California, Ohio, Tennessee, Wyoming) have ruled blockchain timestamps as court-admissible evidence & valid e-signatures. Many of these ruling are recent (within the last 2 months), so it seemed like the perfect time to build this.

Hope you like it!
