> idea of a blockchain as a way for non-trusting parties to quickly and easily agree on truth

Truth of what exactly? It would seem like many useful applications require off-chain oracles which completely subvert the point of the block chain. The only truths I can think of that two non-trusting parties could agree upon is are outputs of deterministic algorithms (i.e. math/logic/hard truth), which has to be utterly useless to the real world, except maybe to harness idle computational to compute prime numbers, PDEs, etc. (i.e. still pretty useless). I'm clearly missing something if all of the hype is warranted and would appreciate if you could point me to any resources/examples that cover this.
