Trait aleph_bft::MultiKeychain

pub trait MultiKeychain: KeyBox {
    type PartialMultisignature: PartialMultisignature
    where
        <Self::PartialMultisignature as PartialMultisignature>::Signature == Self::Signature;

    fn from_signature(
        &self, 
        signature: &Self::Signature, 
        index: NodeIndex
    ) -> Self::PartialMultisignature;
    fn is_complete(
        &self, 
        msg: &[u8], 
        partial: &Self::PartialMultisignature
    ) -> bool;
}

Extends KeyBox with multisigning functionalities.

A single Signature can be rised to a Multisignature. Allows to verify whether a partial multisignature is complete (and valid).

Required Associated Types

type PartialMultisignature: PartialMultisignature
where
    <Self::PartialMultisignature as PartialMultisignature>::Signature == Self::Signature

Required Methods

fn from_signature(
    &self,
    signature: &Self::Signature,
    index: NodeIndex
) -> Self::PartialMultisignature

Transform a single signature to a multisignature consisting of the signature.

fn is_complete(&self, msg: &[u8], partial: &Self::PartialMultisignature) -> bool

Checks if enough signatures have beed added.
