The Vision

Improve the robustness and fault-tolerance of the litep2p crate and bring the crate to a higher level of maturity.

The goal is to stabilize the litep2p and use it as the default backend of Substrate-based chains.

The Plan

To achieve this, we'll focus our efforts on:

• Feature Completeness
  • Implement missing features (validate ping payloads, generate unique random ping payloads, ensure kad records TTL)
• Robustness
  • Ensure core code logic does not panic upon unexpected/malicious user behaviors, panics, unwraps, undocumented expects, array indexing without length validation etc
  • Fix incorrect functionality and divergences from the libp2p specification
  • Repair bugs and limit the surface of race conditions
• Maintenance: keep the code simple
  • Avoid code duplicates (transport layer)
  • Coherent APIs and errors
  • Adopt rust clippy and best practices
  • Improve and add documentation
• Performance Improvements
  • Avoid unnecessary clones
  • Improve the query engine
  • Analyze memory and CPU consumption
• Testing
  • increase code coverage by unit-testing sensitive components (multiselect / noise, kad etc)
  • improve our integration testing scenarios
  • add fuzzing
  • create a plan for continuous testing and triaging in our test stack and keep track of triage reports
