Implementations

source

pub fn random_material() -> Vec<T::Hash>ⓘ
Notable traits for Vec<u8, A>
`impl<A> Write for Vec<u8, A> where A: Allocator,`

Series of block headers from the last 81 blocks that acts as random seed material. This is arranged as a ring buffer with block_number % 81 being the index into the Vec of the oldest hash.

source

impl<T: Config> Randomness<<T as Config>::Hash, <T as Config>::BlockNumber> for Pallet<T>

source

fn random(subject: &[u8 ]) -> (T::Hash, T::BlockNumber )

This randomness uses a low-influence function, drawing upon the block hashes from the previous 81 blocks. Its result for any given subject will be known far in advance by anyone observing the chain. Any block producer has significant influence over their block hashes bounded only by their computational resources. Our low-influence function reduces the actual block producer’s influence over the randomness, but increases the influence of small colluding groups of recent block producers.

WARNING: Hashing the result of this function will remove any low-influence properties it has and mean that all bits of the resulting value are entirely manipulatable by the author of the parent block, who can determine the value of parent_hash.
