Description

This PR adds a tx data version byte incrementing DerivationVersion0 as a way to flag commitments from l1 retrieval vs regular input data from L1 DA.

Tests

Included a unit test to validate that any data without the right byte prefix is forwarded downstream to be parsed as input data.

Additional context

This feature should help with migrating between plasma and L1 DA.

Walkthrough

Walkthrough

The changes involve establishing a new versioning system for plasma commitment transactions in the batch submission process. The introduction of TxDataVersion1 signifies plasma transactions, enhancing compatibility for parsing and ensuring accurate processing. These updates standardize how transaction data is managed and validate data types, offering a more coherent approach to handling plasma transactions across system components.

Changes

Files Change Summary
op-batcher/batcher/driver.go

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit-tests for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit tests for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit tests.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Specs should updated with the fact that we now accept calldata & DA data with the plasma enabled.
