This is a simple script/bot that every 10 minutes grabs the latest NIST random beacon and a few blockhashes from various chains, concatenates them, and timestamps that file. This serves two purposes:
- Timestamps the random beacons, proving they existed prior to a Bitcoin block.
- Injects a commitment to the beacons into the Bitcoin chain, proving that Bitcoin blocks were created after the beacons.
In conjunction with the Restamp Project, this provides evidence that can constrain when Bitcoin blocks were created both forwards and backwards in time.
