Alpha v3.3​

Testnet: June 3

Mainnet: June 11, 10:00 UTC

Breaking change: block time and block size reduction​

Reducing block time to 2 seconds, with a target block size of 24M gas.

The change will increase transaction throughput by approximately 20%, improving user experience by making Linea faster and more responsive.

Actions recommended for node runners

We recommend you adjust your node configurations to ensure any submitted transactions are handled in line with the sequencer.

Besu:

In the besu-sequencer plugin, adjust:

  • plugin-linea-max-tx-gas-limit to 24000000
  • plugin-linea-max-block-gas to 24000000

Geth:

  • In the config .toml file, set [Eth]RPCGasCap to 24000000
    • Or use β€”-rpc.gascap in the command line, again specifying 24000000

Alpha v3.2​

Testnet: May 28

Mainnet: June 4

Smart contract gas optimization​

Upgraded smart contracts to achieve gas optimizations in several areas:

  • Major gas optimizations in blob submission, primarily in LineaRollup.sol
  • Finalization
  • The token bridge.

The upgrade commit is available here.

Code in the upgrade has been audited by:

  • OpenZeppelin, whose report is available here, and;
  • Cyfrin, whose report is here.

Bridge to a different recipient​

note

May 29: Fully functional on testnet; ETH and USDC supported on mainnet.

June 4: Fully functional on mainnet.

The Linea bridge has been upgraded to enable recipient addresses to always be able to claim bridged funds. Bridge transfers to alternative recipients (i.e. an address that isn't the sender's address) now appear on the recipient's "Recent transactions" list, enabling them to claim.

These changes have been audited by OpenZeppelin and Cyfrin.

Alpha v3.1​

Mainnet: May 14

  • Introduces dynamic L1 gwei thresholds for submitting data to L1 for finalization.
  • Adds the eth_sendRawTransaction method, available only via Besu endpoints.

Alpha v3​

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.

L1 and L2 smart contracts have been updated and deployed for Alpha v3. The contract addresses are:

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.

March 27

  • Block time reduced to 3 seconds. This change increases the throughput of the network to avoid any potential L2 execution bottlenecks from increased Linea activity.
  • Gas fee reductions. After EIP-4844 was implemented on March 26, we monitored data for 24 hours before reducing gas fees for all users on March 27.

Breaking changes​

None.

Alpha v2 release notes​

NetworkTarget Release Date
MainnetFebruary 13th, 2024
TestnetJanuary 24, 2024

Summary​

This release focuses on reducing L1 costs, enabling lower prices for end users.

Primarily, the L1 costs are 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.
  • Data compression:
    • This reduces the call data cost on L1 by compressing L2 block data. (Post EIP-4844 this will be stored in blobs)
  • 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

The audited commit for this update can be found here.

Two independent audits have been performed for this update. Reports can be found here:

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.

EventDescriptionStatus
DataFinalized

Emitted at the end of finalization - used to indicate range of finalization

New
BlockFinalized

Deprecated finalization event - indicator that each block has been finalized.

  • Improved Gas Limit Estimation for Finalization on L1: We improved the gas limit estimation for finalization on L1.

Cost efficiency​

  • We updated the L1 message service contract to work with the Merkle tree, reducing gas costs and further enhancing the cost-effectiveness of Linea.

  • We added a fixed cost to the gas price to cover infrastructure costs for system economic sustainability. This change ensures the long-term financial viability of Linea.

User experience​

  • We smoothed the L2 gas price estimation by using an L1 moving average. This update makes our gas price estimation more accurate and reliable.

Linea Alpha v0.2.3 (June 22, 2023)​

Summary​

This release focuses on optimizing the prover's hashing strategy to increase its computational efficiency.

Linea Alpha v0.2.2 (June 20, 2023)​

Summary​

This release focuses on updating the Postman SDK configuration values and revising gas fee calculations.

Features​

  • Updated the Postman SDK configuration files to handle messages that are contract calls with zero ETH value being transferred and revised gas fee calculations.

Linea Alpha v0.2.1 (June 15, 2023)​

Summary​

This release reduces the gas cost of submitting a batch of transactions on L1 by optimizing L2 logs in the calldata that is sent to L1.

Features​

  • Instead of sending the entire event MessageSent, we only send the _messageHash field of the event.

  • Old calldata for L2 originated event:

    //		event MessageSent(
    // address indexed _from,
    // address indexed _to,
    // uint256 _fee,
    // uint256 _value,
    // uint256 _salt,
    // bytes _calldata,
    // bytes32 _messageHash
    // );
  • New calldata for L2 originated event:

      //			bytes32 _messageHash

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 transactions 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
      • 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 L1β†’L2, reduce the mandatory fee for L2β†’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
  • 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
    • If messages don’t get delivered by the postman, the message can be manually claimed by calling claimMessage with the MessageSent event parameters or by using the SDK.
  • 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:

    EventDescription
    L1MessageClaimedWhen a message is claimed
    L1L1L2MessagesReceivedOnL2

    Message hashes have been anchored on L2 and the zkRollup updates the L1 statuses - Includes multiple message hashes

    L1L2L1MessageHashAddedToInbox

    The L2 message hash has been anchored on L1 and can be claimed on block finalization.

    L2MessageSentEmitted when a message is sent
    L2MessageClaimedEmitted when a message is claimed
    L2L1L2MessageHashesAddedToInbox

    L1β†’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 does not reflect final versions.

  • L1 (Goerli):

    • Bridging partners, to send messages, will need to call the new contract address with a different ABI.
