	Unsafe = "latest"
	// Safe is:
	// - L1: Justified checkpoint, beacon chain: 1 epoch of 2/3 of the validators attesting the epoch.

	Safe = "safe"
	// Finalized is:

const (
	// L1ScalarBedrock is implied pre-Ecotone, encoding just a regular-gas scalar.
	L1ScalarBedrock = byte(0)
	// L1ScalarEcotone is new in Ecotone, allowing configuration of both a regular and a blobs scalar.
	L1ScalarEcotone = byte(1)
)

The Ecotone upgrade introduces a versioned L1 scalar format that is backward-compatible with pre-Ecotone L1 scalar values.

Functions

func AddressAsLeftPaddedHash added in v1.4.2 

func AddressAsLeftPaddedHash(addr common.Address) (out common.Hash)

AddressAsLeftPaddedHash converts an address to a hash by left-padding it with zeros. No hashing is performed. This was previously known as Address.Hash(), but removed from go-ethereum in PR 28228, because the naming was not clear.

	l1 L1Client,
	depth int,
	addr common.Address,
) (recentBlock uint64, found bool, err error)

CheckRecentTxs checks the depth recent blocks for transactions from the account with address addr and returns the most recent block and true, if any was found, or the oldest block checked and false, if not.

func DecodeRawReceipts 

func DecodeRawReceipts(block BlockID, rawReceipts []hexutil.Bytes, txHashes []common.Hash) ([]*types.Receipt, error)

DecodeRawReceipts decodes receipts and adds additional blocks metadata. The contract-deployment addresses are not set however (high cost, depends on nonce values, unused by op-node).

func DecodeTransactions 

func DecodeTransactions(data []hexutil.Bytes) ([]*types.Transaction, error)

DecodeTransactions decodes a list of opaque transactions into transactions.

func EncodeReceipts 

func EncodeReceipts(elems []*types.Receipt) ([]hexutil.Bytes, error)

KZGToVersionedHash computes the "blob hash" (a.k.a. versioned-hash) of a blob-commitment, as used in a blob-tx. We implement it here because it is unfortunately not (currently) exposed by geth.

func NewPayloadErr(payload *ExecutionPayload, payloadStatus *PayloadStatusV1) error

func PollBlockChanges 

func PollBlockChanges(log log.Logger, src L1BlockRefsSource, fn HeadSignalFn,
	label BlockLabel, interval time.Duration, timeout time.Duration) ethereum.Subscription

func TransactionsToHashes(elems []*types.Transaction) []common.Hash

TransactionsToHashes computes the transaction-hash for every transaction in the input.

func VerifyBlobProof added in v1.4.2

func WatchHeadChanges 

func WatchHeadChanges(ctx context.Context, src NewHeadSource, fn HeadSignalFn) (ethereum.Subscription, error)

WatchHeadChanges wraps a new-head subscription from NewHeadSource to feed the given Tracker. The ctx is only used to create the subscription, and does not affect the returned subscription.

func (*Blob) FromData added in v1.4.3 

func (b *Blob) FromData(data Data) error

FromData encodes the given input data into this blob. The encoding scheme is as follows:

In each round we perform 7 reads of input of lengths (31,1,31,1,31,1,31) bytes respectively for a total of 127 bytes. This data is encoded into the next 4 field elements of the output by placing each of the 4x31 byte chunks into bytes [1:32] of its respective field element. The three single byte chunks (24 bits) are split into 4x6-bit chunks, each of which is written into the top most byte of its respective field element, leaving the top 2 bits of each field element empty to avoid modulus overflow. This process is repeated for up to 1024 rounds until all data is encoded.

For only the very first output field, bytes [1:5] are used to encode the version and the length of the data.
