Randomness queries.

Required Methods§

source

fn get_randomness_from_tickets( &self, rand_epoch: i64, ) -> Result<[u8; 32], ExecutionError>

Randomness returns a (pseudo)random byte array drawing from the latest ticket chain from a given epoch. This randomness is fork dependant but also biasable because of this.

source

fn get_randomness_from_beacon( &self, rand_epoch: i64, ) -> Result<[u8; 32], ExecutionError>

Randomness returns a (pseudo)random byte array drawing from the latest beacon from a given epoch. This randomness is not tied to any fork of the chain, and is unbiasable.
