# 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`](https://docs.rs/pezpallet-insecure-randomness-collective-flip/latest/pallet_insecure_randomness_collective_flip/struct.Module.html#method.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`](https://docs.rs/pezpallet-insecure-randomness-collective-flip/latest/pallet_insecure_randomness_collective_flip/struct.Module.html)
|
|
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 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(())
|
|
}
|
|
}
|
|
}
|
|
```
