Darwin (v1.0.0)

Overview

The Darwin upgrade introduces a new concept bundle: a list of batches finalized with a single aggregated proof.

Main changes:

• Introduce BatchHeaderV3Codec with 2 new fields added (lastBlockTimestamp, blobDataProof) and one field removed (skippedL1MessageBitmap).
• Process messages in L1MessageQueue during commit step (previously done during the finalize step).
• Introduce a new on-chain verifier public input format in IZkEvmVerifierV2, and adopt it in MultipleVersionRollupVerifier.
• In ScrollChain, introduce two new methods commitBatchWithBlobProof and finalizeBundleWithProof to handle V3 batches and bundles.

The circuit and contract changes have been audited by Trail of Bits.

Compatibility

• Dapps and indexers that decode on-chain batch header data should use the new codec and function signature.
• Dapps and indexers that track finalization status should ensure that they correctly interpret the emitted FinalizeBatch event as "all batches have been finalized up to and including this batch index".
