Struct StmClerk 

Source 
pub struct StmClerk<D: Clone + Digest> { /* private fields */ }
Expand description

Clerk can verify and aggregate SingleSignatures and verify AggregateSignatures. Clerks can only be generated with the registration closed. This avoids that a Merkle Tree is computed before all parties have registered.

Implementations§

Source§

impl<D: Digest + Clone + FixedOutput + Send + Sync> Clerk<D>

Source

pub fn new_clerk_from_closed_key_registration( params: &Parameters, closed_reg: &ClosedKeyRegistration<D>, ) -> Self

Create a new Clerk from a closed registration instance.

Source

pub fn from_registration( params: &Parameters, closed_reg: &ClosedKeyRegistration<D>, ) -> Self

👎Deprecated since 0.5.0: Use new_clerk_from_closed_key_registration instead

Create a new Clerk from a closed registration instance.

Source

pub fn new_clerk_from_signer(signer: &Signer<D>) -> Self

Create a Clerk from a signer.

Source

pub fn from_signer(signer: &Signer<D>) -> Self

👎Deprecated since 0.5.0: Use new_clerk_from_signer instead

Create a Clerk from a signer.

Source

pub fn aggregate_signatures( &self, sigs: &[SingleSignature], msg: &[u8], ) -> StmResult<AggregateSignature<D>>

👎Deprecated since 0.5.3: Use aggregate_signatures_with_type instead

Aggregate a set of signatures.

Source

pub fn aggregate_signatures_with_type( &self, sigs: &[SingleSignature], msg: &[u8], aggregate_signature_type: AggregateSignatureType, ) -> StmResult<AggregateSignature<D>>

Aggregate a set of signatures with a given proof type.

Source

pub fn aggregate( &self, sigs: &[SingleSignature], msg: &[u8], ) -> StmResult<AggregateSignature<D>>

👎Deprecated since 0.5.0: Use aggregate_signatures instead

Aggregate a set of signatures for their corresponding indices.

This function first deduplicates the repeated signatures, and if there are enough signatures, it collects the merkle tree indexes of unique signatures. The list of merkle tree indexes is used to create a batch proof, to prove that all signatures are from eligible signers.

It returns an instance of AggregateSignature.

Source

pub fn compute_aggregate_verification_key(&self) -> AggregateVerificationKey<D>

Compute the AggregateVerificationKey related to the used registration.

Source

pub fn compute_avk(&self) -> AggregateVerificationKey<D>

👎Deprecated since 0.5.0: Use compute_aggregate_verification_key instead

Compute the AggregateVerificationKey related to the used registration.

Source

pub fn get_registered_party_for_index( &self, party_index: &Index, ) -> Option<(VerificationKey, Stake)>

Get the (VK, stake) of a party given its index.

Source

pub fn get_reg_party( &self, party_index: &Index, ) -> Option<(VerificationKey, Stake)>

👎Deprecated since 0.5.0: Use get_registered_party_for_index instead

Get the (VK, stake) of a party given its index.
