vac:p2p:

  • 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
      • Still need to control inter-message delays between publishers (need to look timeouts/tokio::sleep)
  • ift:2025q1-nimlibp2p-wrapping-ngtcp2:tls_handshake
    • Wrapped some additional functions in nim-ngtcp2#10
      • Had to do this manually, since nimterop had trouble generating the functions
      • Tried using futhark instead, because nimterop repository seems abandoned (and c2nim too). Ended up opening this issue since futhark does not work too well either (requires some manual work afterwards)
    • PR in progress in nim-quic
      • Uses crypto functions from picotls.
      • I’m currently working on creating the PicoTLS context (This but in nim)
  • ift:2025q1-nimlibp2p-wrapping-ngtcp2:certificate_validation
    • Fix invalid certificate generation in nim-libp2p#1209
    • Looking into CI issues on macos-arm64 and windows
  • ift:2025q1-nimlibp2p-maintenance
    • PR refactor(pubsub): do not raise exceptions on publish
  • misc/admin
    • Interviewed 1 candidate for P2P engineer position
    • 2 CC 1 day off
