Overview

fix some typos in comments

Summary by CodeRabbit

• Documentation
  • Improved clarity in test comments for transaction availability.
  • Enhanced explanation of fraud detection in full nodes within the system documentation.

[coderabbitai]

Walkthrough

The recent updates involve refining documentation and enhancing clarity in project components. Specifically, grammatical corrections were made in test comments to improve readability, and the process for detecting and proving state fraud in blockchain nodes was detailed, ensuring the integrity of state transitions.

Changes

File Path	Change Summary
mempool/.../clist_mempool_test.go	Updated comments to correct grammar in the TestTxsAvailable function.
specs/lazy-adr/.../adr-009-state-fraud-proofs.md	Enhanced description of detecting fraudulent state transitions and the generation of State Fraud Proofs.

Poem

🌟🐰 A hop, a skip in the digital space,
📝 Where words align with a coder's grace.
Bugs and frauds, we chase away,
With proofs and tests, we keep them at bay.
🚀 To the moon, our code will race,
In the blockchain's endless embrace. 🌌

101-101: Clarify the sequence of state transitions in fraud detection.

Consider adding a diagram or a step-by-step breakdown to visually represent the sequence of state transitions for detecting fraudulent activities. This could enhance understanding for readers not familiar with the process.

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 testing code 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 testing code 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 testing code.
  • @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.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json
