2026-05-25 Logos storage weekly

Week 21 2026 (Mon May 18 - Fri May 22, 2026) §

Highlights §

• Our cryptographers came back with new ideas from the conference week last week. Balazs is working on a lead for speeding up RLN, which could bring proof times down to 10ms, a 6x improvement over the current, already optimized implementation. Given the critical role of RLN on mix performance, this would be no small feat. It is based on this paper.
• Our LIONESS cipher spec has finally been merged and closed, after a final round of reviews.
• Our first tests with DHT queries over mix have been successful. We are now working on integrating discovery to make it operational on the storage network at large.
• The reference implementation for the Ed25519 key blinding that we are planning to deploy in our future hidden-services is now available.
• We are making solid progress with NAT traversal, and should have a complete implementation covering the full range of options - from port mapped routers to UPnP/PCP/PMP to relay fallbacks - available for testing within a week or two.

Status Integration §

• achieved:
  • started to work on the final PR for the history archives.
• next:
  • Still around 1-day work to have draft PR ready.

Large Data Transport Layer for Mix §

• achieved:
  • WIP: fixing tests for the encoding destination behavior in the Sphinx packet payload (almost done)
• next:
  • creating PR with the corresponding SPEC update
  • continuing the work on the MIX transport

LIONESS Specification §

• achieved:
  • Addressed the review comments on LIONESS specification PR, fixed the math rendering issues, and modified the Mix specification to use LIONESS instead of AES for payload encryption.
  • Discussed and defined the concrete primitives to be used for the LIONESS specification
  • Reference implementation improved with added concrete primitives to match the specification.
  • LIONESS specification PR merged and closed.
• next:
  • Review and help with the Nim implementation of LIONESS and integration with Mix.

Hidden Services Over Mix §

• achieved:
  • Studied Tor specification and implementation of Ed25519 with key blinding and completed a standalone reference implementation
• next:
  • Continue work on specification and implementation:
    • epochs and expiry times
    • Ed25519 Key certificates
    • Hidden services identifiers

Rate Limiting Nullifiers (RLN) §

• achieved:
  • studied further promising RLN proof speed optimization opportunities, based on this paper. (Mix network bandwidth would be probably bottlenecked by RLN proofs as of now)
• next:
  • implement and benchmark

Anonymous DHT Queries §

• achieved:
  • DHT-via-Mix PoC working end-to-end
• next:
  • Analyze Logos Service Discovery (LIP 107) to see how / whether it fits our stack

Integration with Logos Core §

• achieved:
  • Sketch of an agent-based QA tool for the Logos UI app which can test the full Logos Storage Module stack against basecamp: https://github.com/gmega/logos-storage-test-agent
• next:
  • Complete the PR update to the last version for Logos Storage Module
  • Update Logos Storage UI

NAT Traversal §

• achieved:
  • Completed the implementation of NAT Traversal
  • New Docker tests with miniupnpd integration for nim-libplum and NAT Traversal
• next:
  • Review the NAT Traversal PR
  • Add tests to nim-libplum in order to test mapping renewal
