Struct Challenge

pub struct Challenge(/* private fields */);

Expand description

Natural extension of the Curve Point to the Proof-of-Relay challenge. Proof-of-Relay challenge is a secp256k1 curve point.

Implementations§

impl Challenge

pub fn to_ethereum_challenge(&self) -> EthereumChallenge

Converts the PoR challenge to an Ethereum challenge. This is a one-way (lossy) operation, since the corresponding curve point is hashed with the hash value then truncated.

impl Challenge

pub fn from_hint_and_share( own_share: &HalfKeyChallenge, hint: &HalfKeyChallenge, ) -> Result<Self>

Obtains the PoR challenge by adding the two EC points represented by the half-key challenges

pub fn from_own_share_and_half_key( own_share: &HalfKeyChallenge, half_key: &HalfKey, ) -> Result<Self>

Obtains the PoR challenge by converting the given HalfKey into a secp256k1 point and adding it with the given HalfKeyChallenge (which already represents a secp256k1 point).

Trait Implementations§

impl AsRef<[u8]> for Challenge

fn as_ref(&self) -> &[u8] ⓘ

impl BytesRepresentable for Challenge

const SIZE: usize = 33usize

Size of the encoded byte array.

fn into_boxed(self) -> Box<[u8]>

Convenience function to copy this type’s binary representation into a Box.

impl Clone for Challenge

fn clone(&self) -> Challenge

Returns a copy of the value. Read more

1.0.0 · Source§

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