SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the critical need to identify and mitigate risks of chain halts, non-deterministic behavior, and on-chain bugs in CosmosSDK protocol code, ensuring network stability.

Core Features & Use Cases

  • Risk Assessment: Analyzes code changes for potential chain halt vulnerabilities.
  • Determinism Check: Identifies sources of non-deterministic outcomes in on-chain logic.
  • Bug Detection: Scans for common on-chain programming errors, with a focus on the x/ module.
  • Use Case: Before deploying a new protocol upgrade, use this Skill to perform a thorough code review, focusing on critical areas like state transitions and inter-module communication, to prevent network disruptions.

Quick Start

Review the code changes in the current branch for any potential chain halt risks.

FAQPage Schema
How do I review CosmosSDK protocol code for chain halt risks?▼

Reviewing CosmosSDK protocol code for chain halt risks involves performing an in-depth analysis of the `x/` directory to identify potential vulnerabilities like unsorted map iterations that threaten network stability.

What causes non-deterministic behavior in CosmosSDK on-chain logic?▼

Non-deterministic behavior in CosmosSDK on-chain logic is frequently caused by sources like iterating over maps without sorting keys, which this code review process identifies to prevent network consensus failures.

How can I detect on-chain bugs in CosmosSDK modules before a protocol upgrade?▼

Detect on-chain bugs in CosmosSDK modules before a protocol upgrade by performing a thorough code review focusing on critical areas like state transitions and inter-module communication to prevent network disruptions.

Does this chain halt code review process cover the entire CosmosSDK codebase?▼

No, this chain halt code review process specifically focuses on identifying issues within the `x/` directory of the CosmosSDK codebase, targeting protocol security, non-determinism, and state transition vulnerabilities.

Why does iterating over maps without sorting keys cause chain halts in CosmosSDK?▼

Iterating over maps without sorting keys causes chain halts in CosmosSDK because it introduces non-deterministic behavior across different nodes, breaking consensus and halting the network during state transitions.
