Overview

The Euclid upgrade introduces the following contract changes:

  • Introduce a new SystemConfig contract for managing important system parameters.
  • Use the new ZkEvmVerifierPostEuclid on-chain verifier for proofs generated by the new OpenVM prover.
  • Introduce batch codec versions v5, v6, and v7. v5 is a singleton batch for the zktrie-MPT transition verified by the Security Council. v6 is identical in format to v4 and v5 but verification happens using the new OpenVM prover. v7 is a major redesign in the batch encoding.
  • Use the new commitBatches function to commit batches. Now we allow committing multiple batches per transaction. Most of the batch metadata previously stored in calldata is now moved into the blob. The point-evaluation precompile check is moved into the circuits.
  • Migrate to L1MessageQueueV2 which uses a rolling hash to amortize commitment costs.
  • Update and re-enable EnforcedTxGateway.
  • Introduce permissionless mode, in which anyone can step up and commit batches, along with their validity proofs. Permissionless mode is entered if the sequencer stops committing/finalizing batches, or if it stops relaying messages from the L1 message queue.

Compatibility

The above changes introduce numerous subtle and not-so-subtle compatibility concerns. The impact depends on the specific application. For a detailed list, see the corresponding section in the governance proposal.
