This seems a big deal to me for some public, transparent and auditable processes - not just “Lotteries”.

With so many Linux boxes out there with the Intel CPU hardware RNG added into /dev/random,
this could be very widely sourced and difficult to compromise.

	Examined it?
	Using it?
	Running a node?

> The League of Entropy provides public randomness that any user can retrieve from leagueofentropy.com.
> <https://leagueofentropy.com/>
> Users will be able to view the 512-bit string value that is generated every 60 seconds. 
> Why 60 seconds? No particular reason. 
> Theoretically, the randomness generation can go as fast as the hardware allows, but it’s not necessary for most use cases. 
> Values generated every 60 seconds give users 1440 random values in one 24-hour period.

At time of writing, “Index” is 92885.
These seem to be stored and retreivable
