Products that do what Btfy – a blockchain that uses weather observations does
Hi HN, I built Btfy, an experimental blockchain that uses weather observations as a source of unpredictability for consensus The motivation is simple. Proof of Work generates uncertainty by performing computations. I wanted to explore whether we could obtain some of that uncertainty from the real world instead. Btfy combines weather observation data with a Verifiable Delay Function (VDF): Weather Observation Data -> VDF -> Block -> Hash Chain In the current implementation, observation data is collected from multiple locations, a VDF is computed, and the result is used to generate a block.…

I built this over the weekend. Any feedback is appreciated. Please note you will need a WebGL enabled browser. Thank you for checking it out. --UPDATE-- HN Traffic is strangling earthbit. There is sporadic downtime due to the web services I am using, if no transactions appear after a few seconds, then please try again in an hour.
