Struct Challenge 

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

Contains the complete Proof-of-Relay challenge is a secp256k1 curve point.

This is the elliptic curve point corresponding to the Ticket challenge.

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>

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

Note that this is an expensive operation that involves point decompression of the both HalfKeyChallenges.

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

Gets 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).

Note that this is an expensive operation that involves point decompression of the both HalfKeyChallenge and scalar multiplication of the HalfKey with the basepoint.

Trait Implementations

impl Clone for Challenge

fn clone(&self) -> Challenge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Challenge

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

Formats the value using the given formatter.

impl PartialEq for Challenge

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 Copy for Challenge
