Struct BadEncodingFraudProof 

pub struct BadEncodingFraudProof { /* private fields */ }

A proof that the block producer incorrectly encoded ExtendedDataSquare.

A malicious actor may incorrectly extend the original data with the recovery data, thus making it impossible to reconstruct the original information.

Light node cannot detect such behaviour with Data Availability Sampling. When the full node collects all the Shares of a row or column of the ExtendedDataSquare and detects that it was incorrectly encoded, it should create and announce BadEncodingFraudProof so that light nodes can reject this block.

Trait Implementations

impl Clone for BadEncodingFraudProof

fn clone(&self) -> BadEncodingFraudProof

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BadEncodingFraudProof

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

Formats the value using the given formatter.

impl FraudProof for BadEncodingFraudProof

const TYPE: &'static str = "badencoding"

Name of the proof type.

fn header_hash(&self) -> Hash

HeaderHash returns the block hash.

fn height(&self) -> u64

Height returns the block height corresponding to the Proof.

fn validate(&self, header: &ExtendedHeader) -> Result<()>

Checks the validity of the fraud proof.

impl From<BadEncodingFraudProof> for BadEncoding

fn from(value: BadEncodingFraudProof) -> Self

Converts to this type from the input type.

impl PartialEq for BadEncodingFraudProof

fn eq(&self, other: &BadEncodingFraudProof) -> 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 Protobuf<BadEncoding> for BadEncodingFraudProof

fn encode<B>(self, buf: &mut B) -> Result<(), Error>

where B: BufMut,

Encode into a buffer in Protobuf format.

fn encode_length_delimited<B>(self, buf: &mut B) -> Result<(), Error>

where B: BufMut,

Encode with a length-delimiter to a buffer in Protobuf format.

fn decode<B>(buf: B) -> Result<Self, Error>

where B: Buf,

Constructor that attempts to decode an instance from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, Error>

where B: Buf,

Constructor that attempts to decode a length-delimited instance from the buffer.

fn encoded_len(self) -> usize

Returns the encoded length of the message without a length delimiter.

fn encode_vec(self) -> Vec<u8>
