Expand description

Certificate represents a Mithril certificate embedding a Mithril STM multisignature

Fields§

§hash: String

Hash of the current certificate Computed from the other fields of the certificate aka H(Cp,n))

§previous_hash: String

Hash of the previous certificate in the chain This is either the hash of the first certificate of the epoch in the chain Or the first certificate of the previous epoch in the chain (if the certificate is the first of its epoch) aka H(FC(n))

§epoch: Epoch

Cardano chain epoch number

§metadata: CertificateMetadata

Certificate metadata aka METADATA(p,n)

§protocol_message: ProtocolMessage

Structured message that is used to create the signed message aka MSG(p,n) U AVK(n-1)

§signed_message: String

Message that is signed by the signers aka H(MSG(p,n) || AVK(n-1))

§aggregate_verification_key: ProtocolAggregateVerificationKey

Aggregate verification key The AVK used to sign during the current epoch aka AVK(n-2)

§signature: CertificateSignature

Certificate signature

Implementations§

source §

impl Certificate

source

pub fn new<T: Into<String>>( previous_hash: T, epoch: Epoch, metadata: CertificateMetadata, protocol_message: ProtocolMessage, aggregate_verification_key: ProtocolAggregateVerificationKey, signature: CertificateSignature, ) -> Certificate

Certificate factory

source

pub fn compute_hash(&self) -> String

Computes the hash of a Certificate

source

pub fn is_genesis(&self) -> bool

Tell if the certificate is a genesis certificate

source

pub fn is_chaining_to_itself(&self) -> bool

Return true if the certificate is chaining into itself (meaning that its hash and previous hash are equal).

source

pub fn match_message(&self, message: &ProtocolMessage) -> bool

Check that the certificate signed message match the given protocol message.

source

pub fn signed_entity_type(&self) -> SignedEntityType

Get the certificate signed entity type.
