Constants ¶
const ( BlobSize = 4096 * 32 MaxBlobDataSize = (4*31+3)*1024 - 4 EncodingVersion = 0 VersionOffset = 1 // offset of the version byte in the blob encoding Rounds = 1024 // number of encode/decode rounds MaxBlobsPerBlobTx = params.MaxBlobGasPerBlock / params.BlobTxBlobGasPerBlob )
const ( // Unsafe is: // - L1: absolute head of the chain // - L2: absolute head of the chain, not confirmed on L1 Unsafe = "latest" // Safe is: // - L1: Justified checkpoint, beacon chain: 1 epoch of 2/3 of the validators attesting the epoch. // - L2: Derived chain tip from L1 data Safe = "safe" // Finalized is: // - L1: Finalized checkpoint, beacon chain: 2+ justified epochs with "supermajority link" (see FFG docs). // More about FFG: https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/gasper/ // - L2: Derived chain tip from finalized L1 data Finalized = "finalized" )
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
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.

- blockNum containing the last tx and true if any was found
- the oldest block checked and false if no nonce change was found
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 VerifyBlobProof ¶ added in v1.4.2

func (b *Blob) ComputeKZGCommitment() (kzg4844.Commitment, error)
func (*Blob) FromData ¶ added in v1.4.3
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.

type SyncStatus ¶
type SyncStatus struct { // CurrentL1 is the L1 block that the derivation process is last idled at. // This may not be fully derived into L2 data yet. // The safe L2 blocks were produced/included fully from the L1 chain up to _but excluding_ this L1 block. // If the node is synced, this matches the HeadL1, minus the verifier confirmation distance. CurrentL1 L1BlockRef `json:"current_l1"` // CurrentL1Finalized is a legacy sync-status attribute. This is deprecated. // A previous version of the L1 finalization-signal was updated only after the block was retrieved by number. // This attribute just matches FinalizedL1 now. CurrentL1Finalized L1BlockRef `json:"current_l1_finalized"` // HeadL1 is the perceived head of the L1 chain, no confirmation distance. // The head is not guaranteed to build on the other L1 sync status fields, // as the node may be in progress of resetting to adapt to a L1 reorg. HeadL1 L1BlockRef `json:"head_l1"` SafeL1 L1BlockRef `json:"safe_l1"` FinalizedL1 L1BlockRef `json:"finalized_l1"` // UnsafeL2 is the absolute tip of the L2 chain, // pointing to block data that has not been submitted to L1 yet. // The sequencer is building this, and verifiers may also be ahead of the // SafeL2 block if they sync blocks via p2p or other offchain sources. // This is considered to only be local-unsafe post-interop, see CrossUnsafe for cross-L2 guarantees. UnsafeL2 L2BlockRef `json:"unsafe_l2"` // SafeL2 points to the L2 block that was derived from the L1 chain. // This point may still reorg if the L1 chain reorgs. // This is considered to be cross-safe post-interop, see LocalSafe to ignore cross-L2 guarantees. SafeL2 L2BlockRef `json:"safe_l2"` // FinalizedL2 points to the L2 block that was derived fully from // finalized L1 information, thus irreversible. FinalizedL2 L2BlockRef `json:"finalized_l2"` // PendingSafeL2 points to the L2 block processed from the batch, but not consolidated to the safe block yet. PendingSafeL2 L2BlockRef `json:"pending_safe_l2"` // CrossUnsafeL2 is an unsafe L2 block, that has been verified to match cross-L2 dependencies. // Pre-interop every unsafe L2 block is also cross-unsafe. CrossUnsafeL2 L2BlockRef `json:"cross_unsafe_l2"` // LocalSafeL2 is an L2 block derived from L1, not yet verified to have valid cross-L2 dependencies. LocalSafeL2 L2BlockRef `json:"local_safe_l2"` }
SyncStatus is a snapshot of the driver. Values may be zeroed if not yet initialized.
type SystemConfig ¶
type SystemConfig struct { // BatcherAddr identifies the batch-sender address used in batch-inbox data-transaction filtering. BatcherAddr common.Address `json:"batcherAddr"` // Overhead identifies the L1 fee overhead. // Pre-Ecotone this is passed as-is to the engine. // Post-Ecotone this is always zero, and not passed into the engine. Overhead Bytes32 `json:"overhead"` // Scalar identifies the L1 fee scalar // Pre-Ecotone this is passed as-is to the engine. // Post-Ecotone this encodes multiple pieces of scalar data. Scalar Bytes32 `json:"scalar"` // GasLimit identifies the L2 block gas limit GasLimit uint64 `json:"gasLimit"` // EIP1559Params contains the Holocene-encoded EIP-1559 parameters. This // value will be 0 if Holocene is not active, or if derivation has yet to // process any EIP_1559_PARAMS system config update events. EIP1559Params Bytes8 `json:"eip1559Params"` // MarshalPreHolocene indicates whether or not this struct should be // marshaled in the pre-Holocene format. The pre-Holocene format does // not marshal the EIP1559Params field. The presence of this field in // pre-Holocene codebases causes the rollup config to be rejected. MarshalPreHolocene bool `json:"-"` }
SystemConfig represents the rollup system configuration that carries over in every L2 block, and may be changed through L1 system config events. The initial SystemConfig at rollup genesis is embedded in the rollup configuration.
