- Fix serde optional dependency issues by adding dep:serde to serde features (24 crates) - Run zepter to propagate runtime-benchmarks, std, try-runtime, serde, experimental, with-tracing, tuples-96 features - Regenerate umbrella crate with proper feature propagation - Format all TOML files with taplo This resolves check-umbrella and check-zepter CI failures.
DO NOT USE IN PRODUCTION
The produced values do not fulfill the cryptographic requirements for random numbers. Should not be used for high-stake production use-cases.
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 pezpallet 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
use frame_support::traits::Randomness;
#[frame_support::pezpallet]
pub mod pezpallet {
use super::*;
use frame_support::pallet_prelude::*;
use frame_system::pallet_prelude::*;
#[pezpallet::pezpallet]
pub struct Pezpallet<T>(_);
#[pezpallet::config]
pub trait Config: frame_system::Config + pallet_insecure_randomness_collective_flip::Config {}
#[pezpallet::call]
impl<T: Config> Pezpallet<T> {
#[pezpallet::weight(0)]
pub fn random_module_example(origin: OriginFor<T>) -> DispatchResult {
let _random_value = pallet_insecure_randomness_collective_flip::Pezpallet::<T>::random(&b"my context"[..]);
Ok(())
}
}
