Pectra hard fork
This release will see Linea implement approximately four years' of Ethereum protocol upgrades in a matter of weeks: from the London hard fork beforehand this release, all the way through to Prague. Due to the complexity of this process, the upgrade will occur in stages, progressing through hard forks according to the release schedule above.
For Linea users, the upgrade will enable new use cases and experiences through EIP-7702 (coming in Beta v6.0), unlocking access to apps that rely on this capability.
For builders, Linea becoming even more strongly Ethereum-aligned will make the developer experience
more streamlined and closely resemble Ethereum. The upgrade adds support for several opcodes and
precompiles, such as PUSH0 and MCOPY, considerably shortening the list of Linea's differences with Ethereum.
note
EIP-7702 will only be activated in Beta v6.0.
Maru consensus client
Beta v4.0 introduces a new consensus client, Maru, replacing the existing Proof-of-Authority sequencer mechanism, Clique. Maru introduces a QBFT consensus mechanism, and will support Linea's future transition to decentralized sequencing. Initially, only a single Maru node operated by Linea will produce blocks.
Beta v3.1.1
Linea Mainnet: 6 October, 2025
- Made Linea's prover 2x more efficient, reducing the cost of running the Linea infrastructure. In future, this additional efficiency will increase ETH and LINEA burn
Beta v3.1
Linea Mainnet: early/mid-August 2025 (target)
Linea Sepolia: late July 2025 (target)
- Remove sequencer limits. These are no longer required because of the limitless prover introduced in Beta v3.
- Increase throughput
Beta v3.0
Linea Mainnet: early August 2025 (target)
Linea Sepolia: late July 2025 (target)
- Limitless prover: Eliminates the need for the sequencer to enforce module limits, as the prover
can handle complex workloads. This unlocks:
- Higher throughput and TPS
- Stabler gas fees during high-traffic periods
- Faster transaction confirmation during activity peaks.
Note that the higher throughput will not enabled until the sequencer limits are removed in Beta v3.1.
Beta v2.0
Linea Mainnet: June 9, 2025
Linea Sepolia: mid/late May 2025

Alpha v4.0
Mainnet: December 16, 2024
Linea Sepolia: November 27, 2024
This update upgrades several key contracts. Some updates prepare the protocol for the ability to reconstruct the Linea state, while others add granularity to available roles, better preparing them for any required pauses. Many of the contract modifications have also resulted in gas optimizations.
Additionally, we are removing the finalizeBlocksWithoutProof function, and adding functionality
that enables any address to send blob submission and finalization transactions through a call
forwarding contract if no finalization occurs for more than six months. This effectively allows L1
finalization, enabling withdrawal of potentially locked funds.
Code in the upgrade has been audited by:
- OpenZeppelin, whose report is available here,
- Diligence, whose report is available here, and;
- Cyfrin, whose report is here.
Changes in this release:
- Adjust blob submission and finalization events to be state reconstruction-compatible
- This is a breaking change for the event structures. The new structures are below:
/**
* @notice Emitted when compressed data is being submitted and verified successfully on L1.
* @dev The block range is indexed and parent shnarf included for state reconstruction simplicity.
* @param parentShnarf The parent shnarf for the data being submitted.
* @param shnarf The indexed shnarf for the data being submitted.
* @param finalStateRootHash The L2 state root hash that the current blob submission ends on. NB: The last blob in the collection.
*/
event DataSubmittedV3(bytes32 parentShnarf, bytes32 indexed shnarf, bytes32 finalStateRootHash);
/**
* @notice Emitted when L2 blocks have been finalized on L1.
* @param startBlockNumber The indexed L2 block number indicating which block the finalization the data starts from.
* @param endBlockNumber The indexed L2 block number indicating which block the finalization the data ends on.
* @param shnarf The indexed shnarf being set as currentFinalizedShnarf in the current finalization.
* @param parentStateRootHash The parent L2 state root hash that the current finalization starts from.
* @param finalStateRootHash The L2 state root hash that the current finalization ends on.
*/
event DataFinalizedV3(
uint256 indexed startBlockNumber,
uint256 indexed endBlockNumber,
bytes32 indexed shnarf,
bytes32 parentStateRootHash,
bytes32 finalStateRootHash
);DataSubmittedV2becomesDataSubmittedV3,DataFinalizedbecomesDataFinalizedV3(DataFinalizedV2was skipped to align version numbers).- The change also introduced gas optimizations for blob submission and finalization.
- Create granular roles for contracts
LineaRollup,L2MessageServiceandTokenBridge:LineaRollup: Introduce more granular pausing and an additional verifier unsetting roleL2MessageService: Introduce more granular pausingTokenBridge: Previously, all administration functions were managed by a single owner (multisig) role. The update adds role-based access with more granular roles per function, particularly for pausing.
- Remove
finalizeBlocksWithoutProoffunction- The function enabled finalization without proofs. This allowed network activity to continue while fundamental changes, such as changing the state management hashing mechanism, were being made. This is the only time the function was used, and it was primarily retained as a contingency.
- Allow any address to finalize blocks if no finalization has occurred in the last six months
- Add functionality to the
LineaRollupcontract to allow any address to submit valid blobs and valid finalization proofs, generated by running the Linea stack locally, to withdraw funds from L2. The mechanism only works if no finalization has happened for six months. The system is intended as a contingency. - The change enables the
LineaRollupcontract to grant a "fallback operator" theOPERATOR_ROLErequired to submit the blobs and finalization proofs. The "fallback operator" is a message forwarding contract enabling any address to submit this data.
- Add functionality to the
- Bump L1 Solidity version to v0.8.26. Introduces slight gas optimizations.
- Optimize message and new token creation hashing, making it slightly cheaper to send and claim messages.
- Address non-critical findings from previous audit rounds
- Generally clean up error management and interfaces.
Alpha v3.6
Block size changes
Mainnet: September 25
Linea Sepolia: September 25
Increase block limit to 30M units of gas. The transaction limit remains at 24M. Block time also remains the same, at 2 seconds.
Alpha v3.5.2
Transaction exclusion API
Mainnet: September 23
Linea Sepolia: September 18
Introduces an API that can be used to check whether a transaction was rejected because it exceeded the sequencer's trace limits.
Alpha v3.5.1
Linea native bridge UI v2
Mainnet: September 18
Linea Sepolia: September 18
Upgrades the Linea bridge UI.
Alpha v3.5.0
finalized tag
Mainnet: October 9
Linea Sepolia: September 17
Adds support for the finalized tag to the blockParameters strings that can be used in various
JSON-RPC API calls. The tag enables you to confirm whether or not a block has been finalized on L1.
See our guide for more.
Alpha v3.4.1
Reactivate linea_estimateGas
Mainnet: September 30
Linea Sepolia: September 9
Reactivates linea_estimateGas, disabling compatibility
mode.
Alpha v3.4
Mainnet and Testnet: July 30
ENS on Linea
Adds support for Linea Names domains, including a frontend app for users to register and manage their domains. The Linea Names system is comparable to ENS on Ethereum Mainnet, except that domains are limited to one per account and registering requires completion of Proof of Humanity. As the system leverages CCIP Read, which enables L1 to trustlessly query the Linea Names registry through an offchain gateway, Linea Names domains resolve on L1.
Read more about ENS in the user guide here.
CCIP Read
One of the building blocks of ENS on Linea is a custom implementation of CCIP Read, which uses the gateway system introduced in EIP-3668 to enable Linea Names domains to resolve on L1. The key contracts created by ENS have been adjusted by the Linea team to ensure they work with Linea's Sparse Merkle Tree system.
The CCIP Read functionality can be applied to any context where a L1 protocol may benefit from securely querying data on Linea. See our page on CCIP Read for more information and guidance on how to use the relevant contracts.
The Linea repository containing the relevant contracts is here.
Consensys Diligence carried out an audit on Linea Names, available here.
linea_estimateGas mainnet activation
note
Available on Linea Sepolia on July 31; available on Mainnet from August 1.
Activates the linea_estimateGas endpoint for use on Mainnet in compatibility mode.
See our reference page for more information and usage.

- Adds the
eth_sendRawTransactionmethod, available only via Besu endpoints.
Alpha v3.0
Summary
The main objective of Alpha v3 is to implement EIP-4844 on Linea, following its introduction to Ethereum mainnet with the Dencun upgrade on March 13.
Features
March 26: EIP-4844
Begin using blobs to post compressed L2 data to L1, with the aim of reducing data availability
costs. Blobs represent a transient data storage mechanism and an alternative to calldata, and
can be significantly cheaper in L1 ETH costs depending on market demand.
Learn more about EIP-4844
EIP-4844's arrival on Ethereum Mainnet enabled Ethereum L2s to start using a new transaction type
that transports L2 transaction and messaging data to L1 in "blobs". Blobs are a considerably
more cost-efficient alternative to the existing method of posting L2 transaction and messaging data
to L1, which involves sending calldata embedded in a transaction.
With Alpha v3, L2 transaction data is added to blobs. The savings generated by using blobs rather
than calldata mainly derive from avoiding the highly competitive L1 gas fee market.
Since transactions containing calldata have to compete with regular L1 transactions for
block space, L2s are vulnerable to L1 network congestion and the fee spikes it can generate.
Before the transition to using blobs, L1 data availability—i.e. the cost of posting data to L1
in calldata—made up more than 95% of the gas costs on Linea.
Conversely, blobs have their own fee market, completely separate to the regular gas fee market on L1. As a result, L2s like Linea now have an alternative to paying regular gas fees, and can instead compete for blob space.
Due to having an entirely new market designed for L2 data availability, the cost of using blobs
will be a fraction of the cost of using calldata.
L1 and L2 smart contracts have been updated and deployed for Alpha v3. The contract addresses are:
- New verifier contract
- Sepolia (L1): 0x5ca5dBf7Cb8F3f3c92E04B16FF5fCA1cdf147f79

- New L1 message service contract
- Sepolia (L1): 0xB218f8A4Bc926cF1cA7b3423c154a0D627Bdb7E5
- Ethereum Mainnet: 0xd19d4B5d358258f05D7B411E21A1460D11B0876F
- New L2 message service contract
- Linea Sepolia: 0x971e727e956690b9957be6d51Ec16E73AcAC83A7
- Linea Mainnet: 0x508Ca82Df566dCD1B0DE8296e70a96332cD644ec
Smart contract updates will be executed by the Linea Security Council using the Safe multi-sig procedure.
Additionally, all contracts have been audited by OpenZeppelin. You can find the report here.

Alpha v2
| Network | Target Release Date |
|---|---|
| Mainnet | February 13th, 2024 |
| Testnet | January 24, 2024 |
Summary
This release focuses on reducing L1 costs, enabling lower prices for end users.
L1 costs are primarily driven by the following:
-
Proof verification, which is essentially a fixed cost for every batch submission.
-
Hashing the batch submission data to produce the public input of the Plonk verifier.
-
Calldata costs, driven by the size of the batch submission data. This includes all the transaction data from L2, as well as messaging data (one hash per L2 to L1 message).
Features
To decrease L1 costs, we implemented the following features:
- Proof aggregation:
- This allows us to create a set of execution proofs for conflated batches and generates an aggregated proof that verifies that all the batches are correct. Since it takes the same amount of gas to verify an aggregated proof vs. a proof for a single batch of conflated blocks, the average cost of verifying a proof aggregating N proofs is N times cheaper.
Learn more about proof aggregation
Generating a zkSNARK proof on L1 is an essential step for finalizing transactions, as a verified proof demonstrates the integrity and validity of the submitted transactions.
Previously, Linea generated one proof per batch of transactions. After Alpha v2, Linea began to recursively aggregate multiple proofs into one.
The verification process on L1 costs ~400,000 gas — a cost that previously had to be covered for every batch. This gas cost is the same, however, for verifying a single batch of conflated batches (as Linea did in Alpha v1) as it is for verifying an aggregated proof representing multiple batches (as in Alpha v2). A proof that aggregates N proofs is N times cheaper, as the cost remains consistent.
With Alpha v2 upgrades, Linea now averages ~30 batches per final proof, making the process 1/30th as costly as it was in Alpha v1.
- Data compression:
- This reduces the call data cost on L1 by compressing L2 block data. (Post EIP-4844 this will be stored in blobs)
Learn more about data compression
Data compression significantly reduces the cost of posting L2 transaction and messaging data to L1.
The system leverages the Linea prover's ability to operate with a compressed input, meaning it
can decompress calldata or blob data to validate L2 state transitions. The data passed to the
L1 smart contract can therefore be considerably smaller, driving down the sum cost of transactions
in each block.
The data compression algorithm is completely lossless, and can achieve compression ratios of up to 15:1 (where the data is 15 times smaller than its uncompressed state). This affords Linea the ability to submit data about far more transactions in each batch: before Alpha v2, Linea averaged ~150 transactions per batch; afterwards, it averages ~1,500.
As a result, significantly more transactions can be processed for the same computational cost on L1. The combination of blobs and data compression further amplifies the gas fee savings that are passed on to Linea users.
- Switched L2 to L1 messaging anchoring from individual hashes to Merkle trees:
- Due to the size of the Merkle trees (32 messages) requiring only one Merkle root to be anchored, there is a 32x calldata size reduction for message hashes
Smart contract changes
To support these new features, we implemented changes to our smart contracts.
We introduce a VERIFIER_SETTER_ROLE, that will be attributed to the Timelock.sol so that all core
contract upgrades (Rollup and Message and Token bridge) and verifiers are executed through a TimeLock mechanism.
Note that we are also using this upgrade to update the way the type 2 state was calculated; as such we'll
need to call finalizeWithoutProof() to perform a state transition from type2 state v1 to type2 state v2.
The Security Council will first execute the following transactions on L1:
- Assign Operator Role via the Safe to the account for blob submission
- Assign Verifier Setter role via the Safe to the Timelock
- Schedule Set new Verifier at index 0
- Execute Set new Verifier at index 0
- Schedule LineaRollup upgrade (at L1 block N)
- Execute LineaRollup upgrade (at L1 block N)
- Update Zodiac delegate roles from pauseByType(bytes32) → pauseByType(uint8)
The Security Council will then execute the following transactions on L2:
- Schedule L2MessageService upgrade
- Execute L2MessageService upgrade
Post upgrade, Execute the following Security Council transactions on L1:
- Call
finalizeWithoutProof() - Clear verifier mapping at index 6 and 7

Breaking changes
Message claiming
- Parties claiming messages on Layer 1 will need to adjust claiming behavior to account for Merkle Proof generation requests and their submission when claiming a message. This applies to messages sent post upgrading. Pre-existing messages must be claimed with the current approach.
Note
If you are using the Linea Bridge UI, then this is already done for you. If you are a partner/user who manages their claiming outside of the Bridge UI, then we recommend looking at the updated SDK.
Finalization events
- After migration to the new finalization mechanism, the rollup contract will no longer emit finalization
events per block, but will instead emit events for data submission as well as an event indicating the
current point of finalization.
- The calldata will contain only the final block state root hash and final block number.
Note
This is a breaking change for consumers listening to the existing events. The BlockFinalized event will
be replaced by the DataFinalized event.
| Event | Description | Status |
|---|---|---|
DataFinalized | Emitted at the end of finalization - used to indicate range of finalization | New |
BlockFinalized | Deprecated finalization event - an indicator that each block has been finalized. | Old |

Linea Alpha v0.2.0 (June 13, 2023)
Summary
This release focuses on testing a substantial architecture upgrade in preparation for Mainnet launch. It contains multiple improvements and breaking changes, specifically around the messaging layer which is changed to a push model. It also improves EVM prover coverage, and provides batch conflation.
Features
- Add Batch Conflation feature to the sequencer to minimize L1 transaction cost.
- With Batch Conflation, L2 blocks' proofs that should have been independent are instead merged together. Therefore, L1 costs for these blocks’ proofs are divided by the number of merged blocks.
- Improve the following smart contracts:
- Rollup zkEVM: Upgrade the rollup main contract with support for
- Conflation
- Security Council management
- Verifier
- Outer proof system moved from Groth16 to Plonk + custom gates to support efficient Fiat Shamir, c.f.: https://eprint.iacr.org/2022/1072.pdf section 6.2
- Messaging Service
- Changed the message service model by splitting the delivery into anchoring and claiming of messages to allow more flexible workflows, remove the mandatory fee for L1→L2, reduce the mandatory fee for L2→L1
- Canonical Token Bridge: Upgrade from 1-1 ERC-20 basic token bridge to N-N ERC-20 canonical token bridge with reservation and token registry
- Rollup zkEVM: Upgrade the rollup main contract with support for
- Add Postman Service for message execution
- The Postman Service is Linea’s off-chain message delivery service. It’s decentralized, permissionless, and
used to claim messages once the protocol has anchored the message hashes. The first release will only
contain the following scenarios:
- DApps/protocols operating the SDK (to be released) claiming messages and paying for gas
- The protocol can filter messages based on origin or destination smart-contracts
- Linea operating the SDK for dApps/Protocols that aren’t yet integrated
- DApps/protocols operating the SDK (to be released) claiming messages and paying for gas
- If messages don’t get delivered by the postman, the message can be manually claimed by calling
claimMessagewith theMessageSentevent parameters or by using the SDK.
- The Postman Service is Linea’s off-chain message delivery service. It’s decentralized, permissionless, and
used to claim messages once the protocol has anchored the message hashes. The first release will only
contain the following scenarios:
- Update prover to integrate with the new architecture and support Batch Conflation
Breaking changes
Message bridge
-
Bridging partners will need to listen to different events. Modifications to the events are seen below:
Event Description L1 MessageClaimedWhen a message is claimed L1 L1L2MessagesReceivedOnL2Message hashes have been anchored on L2 and the zkRollup updates the L1 statuses - Includes multiple message hashes
L1 L2L1MessageHashAddedToInboxThe L2 message hash has been anchored on L1 and can be claimed on block finalization.
L2 MessageSentEmitted when a message is sent L2 MessageClaimedEmitted when a message is claimed L2 L1L2MessageHashesAddedToInboxL1→L2 message hash has been anchored on L2 and can be claimed on block finalization.
-
The anchoring and execution (claim) process has been separated into 2 steps. The deadline concept has been completely removed.
note
Contracts audit is in progress. This doesn't reflect final versions.
