Randomness Module

The Randomness Collective Flip module provides a random function that generates low-influence random values based on the block hashes from the previous 81 blocks. Low-influence randomness can be useful when defending against relatively weak adversaries. Using this pallet as a randomness source is advisable primarily in low-security situations like testing.

Public Functions

See the Module struct for details of publicly available functions.

Usage

Prerequisites

Import the Randomness Collective Flip module and derive your module's configuration trait from the system trait.

Example - Get random seed for the current block

```rust use framesupport::{declmodule, dispatch, traits::Randomness};

pub trait Trait: frame_system::Trait {}

declmodule! { pub struct Module for enum Call where origin: T::Origin { #[weight = 0] pub fn randommoduleexample(origin) -> dispatch::DispatchResult { let _randomvalue = >::random(&b"my context"[..]); Ok(()) } } } ```
