Functions

func BloomToBytes

func BloomToBytes(bloom types.Bloom) [8][32]byte

BloomToBytes converts a types.Bloom to [8][32]byte slice.

func BytesToBloom

func BytesToBloom(b [8][32]byte) types.Bloom

BytesToBloom converts a [8][32]byte slice to types.Bloom.

func EncodeBlockMetadata

func EncodeBlockMetadata(meta *bindings.TaikoDataBlockMetadata) ([]byte, error)

EncodeBlockMetadata performs the solidity `abi.encode` for the given blockMetadata.

func EncodeBlockMetadataInput

func EncodeBlockMetadataInput(meta *TaikoL1BlockMetadataInput) ([]byte, error)

EncodeBlockMetadataInput performs the solidity `abi.encode` for the given blockMetadataInput.

func EncodeCommitHash

func EncodeCommitHash(beneficiary common.Address, txListHash [32]byte) []byte

EncodeCommitHash performs the solidity `abi.encodePacked` for the given commitHash components.

func EncodeEvidence

func EncodeEvidence(e *TaikoL1Evidence) ([]byte, error)

EncodeEvidence performs the solidity `abi.encode` for the given evidence.

func EncodeProposeBlockInput

func EncodeProposeBlockInput(metadataInput *TaikoL1BlockMetadataInput) ([]byte, error)

EncodeProposeBlockInput encodes the input params for TaikoL1.proposeBlock.

func EncodeProveBlockInput

func EncodeProveBlockInput(
	evidence *TaikoL1Evidence,
) ([]byte, error)

EncodeProveBlockInput encodes the input params for TaikoL1.proveBlock.

func EncodeProveBlockInvalidInput

func EncodeProveBlockInvalidInput(
	evidence *TaikoL1Evidence,
	target *bindings.TaikoDataBlockMetadata,
	receipt *types.Receipt,
) ([][]byte, error)

EncodeProveBlockInvalidInput encodes the input params for TaikoL1.proveBlockInvalid.

func ToExecutableData

func ToExecutableData(header *types.Header) *engine.ExecutableData

ToExecutableData converts a GETH *types.Header to *engine.ExecutableData.

func ToGethHeader

func ToGethHeader(header *BlockHeader) *types.Header

ToGethHeader converts a *BlockHeader to GETH *types.Header.

func TryParsingCustomError

func TryParsingCustomError(originalError error) error

TryParsingCustomError tries to checks whether the given error is one of the custom errors defined the TaikoL1 / TaikoL2's ABI, if so, it will return the matched custom error, otherwise, it simply returns the original error.

func UnpackTxListBytes

func UnpackTxListBytes(txData []byte) ([]byte, error)

UnpackTxListBytes unpacks the input data of a TaikoL1.proposeBlock transaction, and returns the txList bytes.
