Doc packet published for sending sender-anonymous messages over the testnet-0.2 mix network via Logos Chat, routed sender-unlinkably through a 3-hop mixnet.

AnonComms

Zerokit v3.0.0 rearchitecture progresses — PR12 and PR13 merged into develop/v3.0.0; PR14 covering docs and cleanup in flight.

AnonComms

RLN module ported to the Logos Core Rust SDK; Keycard device key explored as an authentication method for acquiring RLN membership.

Establish libp2p mixnet

Modify Sphinx payload encryption to preserve payload integrity

Achieved

Implemented the LIONESS spec for payload encryption — nim-libp2p-mix PR 30

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; identified a SURB header bloat issue similar to sender-generated RLN

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
