//! On-chain randomness generation for authority round
//!
//! This module contains the support code for the on-chain randomness generation used by AuRa. Its
//! core is the finite state machine `RandomnessPhase`, which can be loaded from the blockchain
//! state, then asked to perform potentially necessary transaction afterwards using the `advance()`
//! method.
//!
//! No additional state is kept inside the `RandomnessPhase`, it must be passed in each time.
//!
//! The process of generating random numbers is a simple finite state machine:
//!
//! ```text
//! +
//! |
//! |
//! |
//! +--------------+ +-------v-------+
//! | | | |
//! | BeforeCommit <------------------------------+ Waiting |
//! | | enter commit phase | |
//! +------+-------+ +-------^-------+
//! | |
//! | call |
//! | `commitHash()` | call
//! | | `revealNumber()`
//! | |
//! +------v-------+ +-------+-------+
//! | | | |
//! | Committed +------------------------------> Reveal |
//! | | enter reveal phase | |
//! +--------------+ +---------------+
//! ```
//!
//! Phase transitions are performed by the smart contract and simply queried by the engine.
//!
//! Randomness generation works as follows:
//! * During the commit phase, all validators locally generate a random number, and commit that number's hash to the
//! contract.
//! * During the reveal phase, all validators reveal their local random number to the contract. The contract should
//! verify that it matches the committed hash.
//! * Finally, the XOR of all revealed numbers is used as an on-chain random number.
//!
//! An adversary can only influence that number by either controlling _all_ validators who committed, or, to a lesser
//! extent, by not revealing committed numbers.
//! The length of the commit and reveal phases, as well as any penalties for failure to reveal, are defined by the
//! contract.
//!
//! A typical case of using `RandomnessPhase` is:
//!
//! 1. `RandomnessPhase::load()` the phase from the blockchain data.
//! 2. Call `RandomnessPhase::advance()`.
//!
//! A production implementation of a randomness contract can be found here:
//! https://github.com/poanetwork/posdao-contracts/blob/4fddb108993d4962951717b49222327f3d94275b/contracts/RandomAuRa.sol
