Week 18 2026 (Mon Apr 27 - Fri May 1, 2026) §
Highlights §
- We’ve completed the LIONESS specification for Mix payload encryption: https://github.com/logos-co/logos-lips/pull/329. This should provide the strong guarantees for payload integrity that we are looking for.
- Our PR which adds the dial-back address to AutoNAT v2 has been merged in libp2p: libp2p/nim-libp2p#2354. You can now get the observed address as part of the callback, and use it to e.g. configure your announce address. This will be key in getting easy NAT traversal working for Logos Storage.
- We’ve dug into the Logos Blockchain Poseidon2 hash implementation, discovered a few issues, and helped address them.
- We have implemented and documented a more general version of the Sphinx packet format as part of our effort in providing a reference implementation for our transport layer over Mix. We’ve also created Haskell bindings for the Leopard erasure coding library for that same reason — transport layer will use erasure coding for space-efficient redundancy.
- achieved:
- not working on status-go this week
- next
- creating the final PR in which logosstorage is integrated for the history archive storage, prep work has been done in status-go/pull/7344
AnonComms collaboration §
- achieved:
- Implemented and documented (a more general version of) the Sphinx packet format; started working towards the transport layer
- Completed the LIONESS specification to address the Sphinx payload integrity problem.
- Improved the Implementation of the LIONESS wide-block cipher.
- extracted libp2p mix example to a separate repo to test if it works over QUIC (instead of default TCP): marcinczenko/nim-libp2p-mix-example - potential improvements/fixes for the MIX protocol implementation to be discussed in the AnonComms meeting
- getting through the spec and Haskell reference Haskell implementation (logos-storage/transport-over-mix/ - for now making sure I have Haskell env running and that it builds
- next:
- drafting the first primitive transport (chunking layer) over MIX - WIP
- work out the “compressed address space” proposal for Logos Mix
- implement and document a working version of the transport layer abstraction over Mix
- review and help with the LIONESS Nim implementation.
- continue to work on logos-storage hidden services over Mix:
- Reference implementation of Ed25519 with key blinding
- DOS/spam prevention for hidden services.
- Client authentication and restricted discovery mode
Logos Blockchain collaboration §
- achieved:
- Implemented
arkworks-compatible point compression (Nimbos required it, as Logos Blockchain uses proof compression)
- discovered some issues with the Logos Blockchain Poseidon hash implementation
- achieved:
- Second review of PR which updates the Logos Storage UI to the module builder.
- Second review of PR which updates the Logos Storage Module in order to remove Qt dependency.
- next:
- Provide a last review for Logos Storage Module
- achieved:
- Finalise the UDP experiment: most of the NAT seem to be
Address and Port-Dependent Filter (APDF) as mentioned by this paper. The consequence is a client mode is needed for the DHT.
- Update the NAT Traversal strategy to address the feedback and describe the strategy to retrieve the public IP.
- Add dial-back address seen by peers in AutoNAT v2 in libp2p
- DHT client mode implementation in progress
- Update Nix configuration in Logos Storage Nim
- next:
- Finish the DHT client mode implementation
- Implement the NAT Traversal strategy
Privacy track / research §
- achieved:
- Implemented Haskell bindings for the Leopard erasure coding library (this will be used in the reference implementation of the transport layer over mix protocol)
- next:
