Highlights §

• Implemented LIONESS-based Sphinx payload encryption for the libp2p mix protocol, preserving message integrity end-to-end.
• Published the on-chain specification for the payment protocol as a LIP, and presented the end-to-end Store integration demo at Townhall.
• Published a doc packet for sending sender-anonymous messages over the testnet-0.2 mix network via the Logos Chat UI, routed sender-unlinkably through a 3-hop mixnet.

Create a basic capability discovery module §

• Integrate and dogfood capability discovery in Logos Delivery
  • achieved:
    • Tested service discovery in collaboration with the DST team
    • Opened a PR fixing IP-similarity scoring for IPv6 (PR)
    • Merged the service table bootstrap PR
  • next:
    • Address review comments on the IPv6 PR
    • Dogfood the new libp2p version

Establish libp2p mixnet §

• Modify Sphinx payload encryption to preserve payload integrity

  • achieved: implemented the LIONESS spec for payload encryption (PR)
  • next: test by integrating with Logos Delivery

• Specify and implement extended DoS and exit node abuse protection for libp2p mix

  • achieved:
    • Fixed the clientMode implementation so the chat app no longer advertises itself as a mix node
    • Researched non-RLN alternatives for DoS protection (Tor guards/PoW, Loopix and Nym gateway rate limiting, Nomos Blend’s Proof-of-Quota + Proof-of-Selection); investigated a candidate sender-side quota + provable-selection design, which has a SURB header bloat issue similar to sender-generated RLN
  • next:
    • Address any other errors/issues observed
    • Write up the RLN-vs-alternatives comparison as a research note; unblock and rebase the stake-weighted RLN spec

Deliver de-MLS for p2p group messaging §

• Integrate de-MLS into Logos Chat
  • achieved:
    • Implemented the WallClock service
    • Covered the recovery path for when one steward goes offline
  • next:
    • Run libchat and perform manual testing
    • Work on the initial state design idea

Develop service incentivisation §

• Specify on-chain component for payment protocol

  • achieved: merged PR-299, adding an on-chain component section and overall improvements to the LIP-155 payment streams spec
  • next: further updates depend on upcoming milestones (TBD)

• Implement MVP payment protocol

  • achieved: implemented an end-to-end demo of payment streams with Store integration and presented it (recording) at Townhall
  • next: further work depends on upcoming milestones

Maintain and expand the Zerokit library §

• Rearchitecture Zerokit to support enum-based runtime configuration
  • achieved: addressed comments and merged PR12 and PR13 into the develop v3.0.0 branch; worked on PR14, covering documentation and cleanup
  • next: continue addressing PR14 comments and merge to master

Implement RLN membership allocation service §

• Specify and implement RLN membership allocation service
  • achieved:
    • Ported the RLN module to the Logos Core Rust SDK
    • Updated the Logos Delivery/Chat RLN simulation
    • Experimented with using a Keycard device key as an authentication method for acquiring membership
  • next:
    • Integrate Keycard with the simulation
    • Draft specs for the RLN membership management module

Develop a decentralised oracle for LEZ §

• Specifying oracle mechanism
  • achieved: explored alternative design approaches for the oracle mechanism
  • next: consolidate on the appropriate approach and move forward
