2026-08-31 Messaging Weekly

Highlights

• Logos Delivery:
  • released logos-delivery-module v0.2.1 - shipping multiple bugfixes and an update of underlying logos-delivery library
  • the three fleet-stability fixes merged — a store node that writes nothing is now visible (#4148), and partition maintenance (#4147) and database restarts (#4149) no longer kill the node
  • nim-libp2p 2.3.1 migration landed on master (#4145, #4161)
  • Support mobile platforms in logos-delivery closed — Android and iOS builds repaired and gated in CI

Logos Core

Logos Core Integration — Phase 3

• [Deliverable] Pluggable RLN membership

  • achieved:
    • chore: bump logos delivery to latest master
  • next:
    • PoC: Make RLN API module plugable with logos-delivery

• [Deliverable] Make discovery pluggable in Logos Delivery

  • next:
    • discovery PR train, one IPeerDiscovery interface over discv5, the internal Kademlia backend and an external provider: #1 IPeerDiscovery abstraction, #2 advertise/interest verbs and discv5 decoupling, #3 external backend over a C plugin ABI, #4 reach kademlia discovery from the messaging/channels layers, #5 advertise this node on the delivery network, #6 ship the service-discovery plugin header

• [Deliverable] POC: Delivery module uses Discovery module for peer discovery

  • next:
    • the delivery module runs kademlia service discovery hosted by libp2p_module instead of in-process — two parallel PRs showing the same wiring, differing only in how the module reaches libp2p: runtime client, declared dependency

Status

Status: Logos Delivery Integration

• [Deliverable] Support mobile platforms in logos-delivery — closed

  • achieved:
    • mobile support: fix: android support, fix: ios support — both builds had been broken since the Nimble migration with no CI job to catch it; liblogosdelivery now builds for Android and iOS on every PR

• [Deliverable] Integrate Messaging API in status-go

  • achieved:
    • Go bindings:
      • define Nim dependency using Nimble (#121)
      • provide access to Kernel API when using Messaging API (#122)
      • kernel suite passes and now runs on every PR (#125, #126, #127)
    • Consistently surface payload fields as base64-encoded (#4170)
  • next:
    • fix: send one multiaddress per peer and never a zero timeout
  • blocked:
    • Link liblogosdelivery through Go bindings using Nimble (#7731) — blocked by #7757, which moves status-go’s Nim dependencies onto Nimble

Maintenance

• achieved:
  • fleet stability: #4148, #4147, #4149
  • feat: migrate to nim-libp2p 2.2.1, with nim-libp2p-mix#54 and chore: pin boringssl v0.0.11, then chore: bump nim-libp2p to v2.3.1
  • fix(build): constrain and verify Nimble dependency setup — Nimble 0.24.1, lock-derived constraints, same path in Make and CI — and chore: bump to nim 2.2.6
  • nim-sds: review follow-ups, nim-testutils: declare the results dependency
  • fix(conf): drop duplicated dnsDiscovery name servers — blocks moving the sandbox fleet to enrtree:// (#4146)
• next:
