Indeed, there was a service I used back in around 2008 that did just this. It wasn't about predictions per se, but timestamping content. They were called GuardTime. The company still exists, but the service does not seem to, anymore. It wasn't based on a public, distributed block chain, but it was a kind of a block chain (without PoW, PoS etc. - which you don't need if it's run by a single actor). The way they built trust was that they did publish their hash (tip of the block chain) I think in the (printed) Financial Times periodically. That made it impossible even for them to forge the chain. |
