Summary of Changes
Hello @tac0turtle, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request primarily updates the project's README.md to document recent architectural changes, specifically the integration and functionality of a custom consensus layer. The update aims to provide clarity on how the system now handles block timestamps to accommodate Rollkit's unique requirements.
Highlights
- Documentation Update: The
README.mdhas been updated to reflect the introduction of a custom consensus layer within the project. - Custom Consensus Layer Details: New documentation details the
RollkitConsensusimplementation, explaining its ability to allow blocks with identical timestamps (header.timestamp >= parent.timestamp) and its critical role in supporting Rollkit's block production model. - Project Structure Reference: The
README.mdnow includes a specific reference to thecrates/rollkit/src/consensus.rsfile, clarifying its purpose as the location for the custom consensus implementation.

Code Review
This pull request updates the README file to document the new custom consensus mechanism. The changes accurately reflect the new feature by adding it to the feature list, providing a detailed explanation, and updating the architectural overview and file tree diagram. I've provided a couple of suggestions to improve the clarity and consistency of the new documentation sections.
| - Allows multiple blocks to have the same timestamp | ||
| - Wraps the standard Ethereum beacon consensus for most validation | ||

The first and last bullet points in this list are repetitive. They can be combined to make the description more concise and easier to read.

For consistency with other parts of the documentation (e.g., line 43), it's better to use header.timestamp >= parent.timestamp instead of parent.timestamp <= header.timestamp. While mathematically equivalent, the former is more conventional when describing block progression.

12-13: Consider linking to the implementation for quicker navigationReaders may want to jump directly to the
crates/rollkit/src/consensus.rsimplementation you reference here.
Appending a relative link (e.g.([source](crates/rollkit/src/consensus.rs))) would improve discoverability without bloating the text.
37-45: Tighten wording & eliminate duplication in the timestamp rule descriptionYou describe the rule change twice (≥ vs >). Condense to a single sentence to avoid reader confusion and remove redundancy:
-Only modifies timestamp validation to accept `header.timestamp >= parent.timestamp` instead of requiring strictly greater timestamps +Replaces the strict `header.timestamp > parent.timestamp` rule with `>=`, allowing equal-timestamp blocks
183-187: Use consistent inequality direction across documentationAbove you state “
header.timestamp >= parent.timestamp”; here the bullet flips the operands (“parent.timestamp <= header.timestamp”).
Although mathematically equivalent, keeping the same orientation avoids mental friction.Update to mirror the earlier form or vice-versa, but choose one.

Double-check the file actually exists on this branch; broken tree references in README will frustrate newcomers.
