Take block-chain insanity out of this, and a distributed reliable consistent unpredictable random value feels like a socially useful thing.

Put signed public ledger (which is block chain shed of the economic games to ICO) back on the table, and It feels like this, alongside a trusted third party time stamp, would become enabling technology for a non-repudiation 'happened on this day' service.

I would prefer to use GPS than NIST. If this is combined with mix-in from Glonass and Galileo, Does it get stronger or weaker?
