vac:p2p:

  • ift:2025q1-gossipsub-perf-improvements
    • Created talk on GossipSub v1.4 proposal for virtual libp2p day
    • Created PR for nim, go, rust test nodes
      • Fixed some isses with gossipsubv2.0 simulation, but it still runs for v. small number of messages / network size
    • Worked on running nimbus in EthShadow (Still a WiP)
  • ift:2025q1-nimlibp2p-wrapping-ngtcp2:tls_handshake
    • nim-quic#c3bf40 fix: ALPN buffer FFI
    • nim-libp2p#1298 refactor: use openssl instead of mbedTLS
      • mbedtls fails to compile in arm64 (there’s an open issue in their repo)
      • we are already using openssl so mbedtls is not really needed for now
      • If ngtcp2 releases a version that can use mbedtls succesfully, and mbedtls fixes their compilation issues, we can consider removing openssl then and use mbedtls.
    • nim-quic#64 fix: handle handshake failures on client side
    • nim-quic#65 feat: wait for handshake on incoming connection and get access to certificate chain
    • nim-libp2p#1301 feat: withQuicTransport
    • nim-libp2p#1302 fix: set peerId on incoming Quic connection
    • Finally, merged the nim-quic and nim-libp2p feature PR. This task is 100% complete
  • ift:2025q1-nimlibp2p-wrapping-ngtcp2:certificate_validation
    • rebasing and merging open PRs
    • feat(certificate): add date verification #1299
      • adds parameters for certificate valid from/to times
    • chore(quic): add tests with invalid certs #1297
      • finished implementing test cases, improved test logic
    • libp2p/specs: update certificate test vectors #665
      • meet demands from maintainers
  • vac:p2p:ift:2025q2-nimlibp2p-transport:memory-transport

  • ift:2025q1-de-mls-multi-admin:batch-key-package
    • Added handling of messages to join group once with batches and once in epoch PR
  • ift:2025q1-zerokit-v0-8:zerokit-wasm-research

    • Finalized presentation and presented at IFT research call.
  • ift:2025q1-libp2p-mix-poc:simple-gossipsub-poc
    • Identified a potential issue in GossipSub PoC
      • When the handler is invoked by the abstract connection from the local Mix instance, it might be mistaken for an actual connection, triggering subscription messages and possibly peer scoring. Further investigation required.
    • Progressing on a mixified version of the Dockerized GossipSub test for DST (in progress, branch).
      • Still figuring out a way for mix nodes to load public info of all other mix nodes during bootup, especially when other nodes may not have started yet.
  • ift:2025q1-libp2p-mix-poc:update-rfc
    • Began working on the Mix RFC (in progress).
  • ift:2025q1-think-tank

  • ift:2025q2-zerokit-v0-8:zerokit-wasm-implementation
    • Continued working on WebAssembly support for ZeroKit (PR).
      • Refactored the rln module by moving circuit-related files to src/circuit for better organization.
      • Removed ark-circom and wasmer from the rln module, reducing build size and improving compilation speed and CI workflow efficiency in the zerokit-wasm-research branch.
      • Benchmarked rln-wasm module, covering RLN instance creation, key generation, witness calculation, proving, and verification. Added these benchmarks to v0.6.1 in the benchmark-v0.6.1 branch, as well as on an older version of zerokit-wasm-research before ark-circom and wasmer were removed for comparison.
