Struct Initializer 

pub struct Initializer {
    pub stake: Stake,
    pub parameters: Parameters,
    pub bls_signing_key: BlsSigningKey,
    pub bls_verification_key_proof_of_possession: VerificationKeyProofOfPossessionForConcatenation,
}

Structure responsible of creating a signer

Fields

stake: Stake

Stake of the participant

parameters: Parameters

Protocol parameters.

bls_signing_key: BlsSigningKey

Signing key for concatenation proof system.

bls_verification_key_proof_of_possession: VerificationKeyProofOfPossessionForConcatenation

Verification key for concatenation proof system.

Implementations

impl Initializer

pub fn new<R: RngCore + CryptoRng>( parameters: Parameters, stake: Stake, rng: &mut R, ) -> Self

Creates a new initializer

pub fn try_create_signer<D: MembershipDigest>( self, closed_key_registration: &ClosedKeyRegistration, ) -> StmResult<Signer<D>>

Attempts to generate a new signer from the current registration state.

Process

1. Verifies that registration is closed (determined by total stake threshold)
2. Confirms the initializer is registered and retrieves its signer index
3. Constructs the Merkle tree commitment
4. Creates the underlying proof system signer (currently only the concatenation proof system)

Errors

Returns an error if:

• Registration is not yet closed
• The initializer is not registered

pub fn get_verification_key_proof_of_possession_for_concatenation( &self, ) -> VerificationKeyProofOfPossessionForConcatenation

Extract the verification key with proof of possession.

pub fn to_bytes(&self) -> [u8; 256]

Convert to bytes

Layout

• Stake (u64)
• Params
• Secret Key
• Public key (including PoP)

pub fn from_bytes(bytes: &[u8]) -> StmResult<Initializer>

Convert a slice of bytes to an Initializer

Error

The function fails if the given string of bytes is not of required size.

Trait Implementations

impl Clone for Initializer

fn clone(&self) -> Initializer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Initializer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Initializer

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Initializer> for RegistrationEntry

fn from(initializer: Initializer) -> Self

Converts to this type from the input type.

impl PartialEq for Initializer

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Initializer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
