impl<T> Pallet<T>where
T: Config,
Methods for the ValidateUnsigned
implementation:
It restricts calls to report_equivocation_unsigned
to local calls (i.e. extrinsics generated
on this node) or that already in a block. This guarantees that only block authors can include
unsigned equivocation reports.
pub fn validate_unsigned( source: TransactionSource, call: &Call<T>, ) -> Result<ValidTransaction, TransactionValidityError>
pub fn pre_dispatch(call: &Call<T>) -> Result<(), TransactionValidityError>

T: Config,
pub fn report_equivocation(
origin: <T as Config>::RuntimeOrigin,
equivocation_proof: Box<EquivocationProof<<T as Config>::Hash, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>,
key_owner_proof: <T as Config>::KeyOwnerProof,
) -> Result<PostDispatchInfo, DispatchErrorWithPostInfo<PostDispatchInfo>>
pub fn report_equivocation( origin: <T as Config>::RuntimeOrigin, equivocation_proof: Box<EquivocationProof<<T as Config>::Hash, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>, key_owner_proof: <T as Config>::KeyOwnerProof, ) -> Result<PostDispatchInfo, DispatchErrorWithPostInfo<PostDispatchInfo>>
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.
pub fn report_equivocation_unsigned(
origin: <T as Config>::RuntimeOrigin,
equivocation_proof: Box<EquivocationProof<<T as Config>::Hash, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>,
key_owner_proof: <T as Config>::KeyOwnerProof,
) -> Result<PostDispatchInfo, DispatchErrorWithPostInfo<PostDispatchInfo>>
pub fn report_equivocation_unsigned( origin: <T as Config>::RuntimeOrigin, equivocation_proof: Box<EquivocationProof<<T as Config>::Hash, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>, key_owner_proof: <T as Config>::KeyOwnerProof, ) -> Result<PostDispatchInfo, DispatchErrorWithPostInfo<PostDispatchInfo>>
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.
pub fn note_stalled(
origin: <T as Config>::RuntimeOrigin,
delay: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number,
best_finalized_block_number: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number,
) -> Result<(), DispatchError>
pub fn note_stalled( origin: <T as Config>::RuntimeOrigin, delay: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, best_finalized_block_number: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, ) -> Result<(), DispatchError>
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.

T: Config,
pub fn state() -> StoredState<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>
pub fn state() -> StoredState<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>
State of the current authority set.
pub fn pending_change() -> Option<StoredPendingChange<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, <T as Config>::MaxAuthorities>>
pub fn pending_change() -> Option<StoredPendingChange<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, <T as Config>::MaxAuthorities>>
Pending change: (signaled at, scheduled change).
pub fn next_forced() -> Option<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>
pub fn next_forced() -> Option<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>
next block number where we can force a change.
pub fn stalled() -> Option<(<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number)>
pub fn stalled() -> Option<(<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number)>
true
if we are currently stalled.
pub fn current_set_id() -> u64
pub fn current_set_id() -> u64
The number of changes (both in terms of keys and underlying economic responsibilities) in the “set” of Grandpa validators from genesis.
pub fn session_for_set(set_id: u64) -> Option<u32>
pub fn session_for_set(set_id: u64) -> Option<u32>
A mapping from grandpa set ID to the index of the most recent session for which its members were responsible.
This is only used for validating equivocation proofs. An equivocation proof must contains a key-ownership proof for a given session, therefore we need a way to tie together sessions and GRANDPA set ids, i.e. we need to validate that a validator was the owner of a given key on a given session, and what the active set ID was during that session.
Get the current set of authorities, along with their respective weights.
pub fn schedule_pause(
in_blocks: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number,
) -> Result<(), DispatchError>
pub fn schedule_pause( in_blocks: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, ) -> Result<(), DispatchError>
Schedule GRANDPA to pause starting in the given number of blocks. Cannot be done when already paused.
pub fn schedule_resume(
in_blocks: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number,
) -> Result<(), DispatchError>
pub fn schedule_resume( in_blocks: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, ) -> Result<(), DispatchError>
Schedule a resume of GRANDPA after pausing.
pub fn schedule_change(
next_authorities: Vec<(Public, u64)>,
in_blocks: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number,
forced: Option<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>,
) -> Result<(), DispatchError>
pub fn schedule_change( next_authorities: Vec<(Public, u64)>, in_blocks: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, forced: Option<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>, ) -> Result<(), DispatchError>
Schedule a change in the authorities.
The change will be applied at the end of execution of the block
in_blocks
after the current block. This value may be 0, in which
case the change is applied at the end of the current block.
If the forced
parameter is defined, this indicates that the current
set has been synchronously determined to be offline and that after
in_blocks
the given change should be applied. The given block number
indicates the median last finalized block number and it should be used
as the canon block when starting the new grandpa voter.
No change should be signaled while any change is pending. Returns an error if a change is already pending.
pub fn submit_unsigned_equivocation_report(
equivocation_proof: EquivocationProof<<T as Config>::Hash, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>,
key_owner_proof: <T as Config>::KeyOwnerProof,
) -> Option<()>
pub fn submit_unsigned_equivocation_report( equivocation_proof: EquivocationProof<<T as Config>::Hash, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>, key_owner_proof: <T as Config>::KeyOwnerProof, ) -> Option<()>
Submits an extrinsic to report an equivocation. This method will create
an unsigned extrinsic with a call to report_equivocation_unsigned
and
will push the transaction to the pool. Only useful in an offchain
context.
