On-Chain Random Numbers
We are introducing an on-chain RNG based on RANDAO. It may be leveraged by smart contract developers to introduce random numbers into their applications. Note that random numbers are limited to certain blocks in the current implementation. See below for more information.
The following article explains on-chain randomness functions and how they will be used when POSDAO is implemented. It includes concepts and an example, and is a good place to start.

The current implementation requires a chain running OpenEthereum AuRa consensus mechanism with version 2.7.2+. The Random Number generation contract was introduced in this PR.
