Verifiable public ledger / dare I say it "block chain"

[joonas-fi]

Features

• A beautiful UI and URLs for verifying data, shows hierarchy right up to root with proof links
• Rate limiting, prevent abuse from bad actors
• Base URLs for each leaf chain operator in central registry, so block proof URLs don't break when chain operator URL inevitably changes
• Hierarchy of days -> hours -> individually operated chain.
• Blocks closer to root are public and verifiable. Blocks closer to leaf are usually private, and verifiable only if the user wants to present the proof.

Things you can notarize

• Your files
• Sensor data like video feeds, GPS traces, heart rate etc.
• All content in Varasto, if you choose to

Proof channels

• Twitter
• Internet archive?
• Bitcoin? ugh.
