12:12:00 +07:00 Open Timestamps - "A timestamping proof standard, OpenTimestamps aims to be a standard format for blockchain timestamping." - Use the bitcoin blockchain to create timestamps so you can verify that a particular bit of content existed at a particular moment in time. I'd like to integrate something like this into my static site generator at some point. The website isn't loading the CSS, so not sure if it's still maintained. Sounds like a cool project though. opentimestamps.org #
