Grandpa::Call

Variant 143 v411

pallet_grandpa::pallet::Call

Contains a variant per dispatchable extrinsic that this pallet has.

About This Type

Call enum for the Call pallet.

Contains all dispatchable functions (extrinsics) for the Call pallet. Each variant represents a different callable function with its parameters.

Variants (3)

Index	Name	Fields	Docs
0	report_equivocation	equivocation_proof: EquivocationProof key_owner_proof: Void	Report voter equivocation/misbehavior. This method will verify the equivocation proof and validate the given key ownership proof against the extracted offender. If both are valid, the offence will be reported.
1	report_equivocation_unsigned	equivocation_proof: EquivocationProof key_owner_proof: Void	Report voter equivocation/misbehavior. This method will verify the equivocation proof and validate the given key ownership proof against the extracted offender. If both are valid, the offence will be reported. This extrinsic must be called unsigned and it is expected that only block authors will call it (validated in `ValidateUnsigned`), as such if the block author is defined it will be defined as the equivocation reporter.
2	note_stalled	delay: u32 best_finalized_block_number: u32	Note that the current authority set of the GRANDPA finality gadget has stalled. This will trigger a forced authority set change at the beginning of the next session, to be enacted `delay` blocks after that. The `delay` should be high enough to safely assume that the block signalling the forced change will not be re-orged e.g. 1000 blocks. The block production rate (which may be slowed down because of finality lagging) should be taken into account when choosing the `delay`. The GRANDPA voters based on the new authority will start voting on top of `best_finalized_block_number` for new finalized blocks. `best_finalized_block_number` should be the highest of the latest finalized block of all validators of the new authority set. Only callable by root.

const registry = new TypeRegistry();

// Encode Grandpa::Call — variant "report_equivocation"
const value = registry.createType("Grandpa::Call", { report_equivocation: { equivocation_proof: 0, key_owner_proof: 0 } });
console.log("Hex:", value.toHex());
