    • nim-libp2p#1389 chore: make quic optional
      • Nimbus does not want runtime dependencies when quic is not being used
      • Added a compile time flag that will determine whether Quic is going to be compiled or not
      • Ended up creating v1.10.1 so nimbus would not be stopped from updating nim-libp2p version
    • nim-libp2p#1392 chore: move -d:libp2p_quic_support flag to .nimble
    • nim-libp2p#1390 chore(version): update libp2p.nimble to 1.10.1
    • investigate why ci was failing (interop tests and unit tests)
      • identified two issues
        • quic: framesorted did not reset all values
        • quic: timeouts was not behaving correctly
          • proposed fix nim-quic#72, that was later on improved by richard

  • ift:2025q2-zerokit:semaphore-parts-bench
    • Reviewed benchmarks result and report report
  • ift:2025q2-zerokit:release
    • Start updating readme for the release
  • ift:2025q2-rln-status-l2:rpc-node-modification
    • Meeting on Gasless Linea Besu discussion -> not plugin but a linea node modification
    • Implement a plugin for RPC nodes to forward transaction data directly to the Prover.
      • Implementaion is on this repo
      • Changed approach for implementing the RPC node using the Linea-Besu codebase instead of Besu plugin feature.
  • ift:2025q2-rln-status-l2:prover-service
  • ift:2025q2-de-mls-tesnet:blogpost-de-mls-over-waku
    • Create a doc with new changes with a diagram
  • ift:2025q2-libp2p-mix-testnet:dockerize
    • Investigated incorrect logging of msgId and origin timestamps in mix nodes.
    • Confirmed the message is already GossipSub-processed; recovering original metadata requires identifying the byte offset where the payload begins.
    • Reviewed PR #20 and flagged issues with msgId and timestamp extraction at intermediate hops and identifying the byte offset.
  • ift:2025q2-libp2p-mix-testnet:update-rfc
    • Continued refactoring the Mix Protocol RFC PR #158

    • Began design work on SURB-based reply mechanism.
    • Early concern: if fragmentation remains external to Mix Protocol, recipients may need multiple SURBs to reply. This blocks replies unless the sender pre-supplies sufficient SURBs.
    • PR 20
      • Began properly familiarising.
      • Upstreamed the node testing into the poc branch (this avoids having to push to github any upstream dependency changes)

      • confirmed resiliancy at large-value msg-ids
  • nes:2025q2-nescience-consulting:unifying-q1-docs
  • nes:2025q2-nescience-consulting:SE-DE-improvements
    • Began work on SE/DE improvements and sync.
      • Determined non-membership proof is likely the only optimisation for DE; changing nullifier tree structure to support BST would result in more drawbacks.
      • Examined edge cases to refine SE.
  • ift:2025q2-rln-status-l2:rln-spec
    • Init a doc for RLN deployment spec. Prover side mostly done.
