Types

type TxListDecompressor

type TxListDecompressor struct {
	// contains filtered or unexported fields
}

TxListDecompressor is responsible for validating and decompressing the transactions list in a TaikoL1.proposeBlock transaction.

func NewTxListDecompressor

func NewTxListDecompressor(
	blockMaxGasLimit uint64,
	maxBytesPerTxList uint64,
	chainID *big.Int,
) *TxListDecompressor

NewTxListDecompressor creates a new TxListDecompressor instance based on giving configurations.

func (*TxListDecompressor) TryDecompress

func (v *TxListDecompressor) TryDecompress(
	blockID *big.Int,
	txListBytes []byte,
	blobUsed bool,
) []byte

TryDecompress validates and decompresses whether the transactions list in the TaikoL1.proposeBlock transaction's input data is valid, the rules are: - If the transaction list is empty, it's valid. - If the transaction list is not empty:

1. If the transaction list is using calldata, the compressed bytes of the transaction list must be less than or equal to maxBytesPerTxList.
2. The transaction list bytes must be able to be RLP decoded into a list of transactions.

func (*TxListDecompressor) TryDecompressHekla

func (v *TxListDecompressor) TryDecompressHekla(
	blockID *big.Int,
	txListBytes []byte,
	blobUsed bool,
) []byte

TryDecompressHekla is the same as TryDecompress, but it's used for Hekla network with an incorrect legacy bytes size check. ref: https://github.com/taikoxyz/taiko-client/pull/783
