• ift:2025q1-gossipsub-perf-improvements
  • Finalized staggered message sending article (Only tagguy’s feedback part is left).
  • Created rust-libp2p gossipsub simulation for shadow. Latency, bandwidth computations are working fine
    • Still need to add hooks for additional stats

  • PR in progress in nim-quic
    • Uses crypto functions from picotls.
    • I’m currently working on creating the PicoTLS context (This but in nim)
