Substrate Differential Pallet

This is a Substrate pallet that allows to configure the distribution of the block weight between the pallets. The configuration is done while the runtime is being constructed. The extrinsic filtering logic is implemented in the corresponding SignedExtension.

Usage

• Add the dependency to your Cargo.toml:

substrate-differential = { version = "0.1", default-features = false, git = "https://github.com/kalaninja/substrate-differential.git" }

• Add the pallet to your runtime:

parameter_types! {
    pub PalletsWeightDistribution: substrate_differential::limits::PalletsWeightDistribution =
        substrate_differential::limits::PalletsWeightDistribution::build_with::<PalletInfo>()
            .add::<Balances>(Perbill::from_percent(30))
            .add::<Sudo>(Perbill::from_percent(10))
            .build_or_panic();
}

impl substrate_differential::Config for Runtime {
    type RuntimeCall = RuntimeCall;
    type PalletsWeightDistribution = PalletsWeightDistribution;
}

construct_runtime!(
    pub struct Runtime
    where
        Block = Block,
        NodeBlock = opaque::Block,
        UncheckedExtrinsic = UncheckedExtrinsic,
    {
        // ...
        Differential: substrate_differential,
    }
);

• Add the DifferentiatePallets extension in the SignedExtra checklist:

pub type SignedExtra = (
    // ...
    substrate_differential::DifferentiatePallets<Runtime>,
);

• cargo build --release

Sample

The example usage is available in the substrate-differential-sample repository.
