Types ¶
type BadEncodingProof ¶
type BadEncodingProof struct {
BlockHeight uint64
// Shares that did not pass verification in rmst2d will be nil.
// For non-nil shares MerkleProofs are computed.
Shares []*ipld.ShareWithProof
// Index represents the row/col index where ErrByzantineRow/ErrByzantineColl occurred
Index uint8
// contains filtered or unexported fields
}
func (*BadEncodingProof) Height ¶
func (p *BadEncodingProof) Height() uint64
Height returns block height
func (*BadEncodingProof) MarshalBinary ¶
func (p *BadEncodingProof) MarshalBinary() ([]byte, error)
MarshalBinary converts BadEncodingProof to binary
func (*BadEncodingProof) Type ¶
func (p *BadEncodingProof) Type() ProofType
Type returns type of fraud proof
func (*BadEncodingProof) UnmarshalBinary ¶
func (p *BadEncodingProof) UnmarshalBinary(data []byte) error
UnmarshalBinary converts binary to BadEncodingProof
func (*BadEncodingProof) Validate ¶
func (p *BadEncodingProof) Validate(header *header.ExtendedHeader) error
Validate ensures that fraud proof is correct. Validate checks that provided Merkle Proofs correspond to the shares, rebuilds bad row or col from received shares, computes Merkle Root and compares it with block's Merkle Root.
type Proof ¶
type Proof interface {
// Type returns the exact type of fraud proof
Type() ProofType
// Height returns the block height corresponding to the Proof
Height() uint64
// Validate check the validity of fraud proof.
// Validate throws an error if some conditions don't pass and thus fraud proof is not valid
// NOTE: header.ExtendedHeader should pass basic validation otherwise it will panic if it's malformed
Validate(*header.ExtendedHeader) error
encoding.BinaryMarshaler
encoding.BinaryUnmarshaler
}
Proof is a generic interface that will be used for all types of fraud proofs in the network.
func CreateBadEncodingProof ¶
func CreateBadEncodingProof( height uint64, errByzantine *ipld.ErrByzantine, ) Proof
CreateBadEncodingProof creates a new Bad Encoding Fraud Proof that should be propagated through network The fraud proof will contain shares that did not pass verification and their relevant Merkle proofs.
