Key Highlights

Blockchain

Sessions fully removed from the Logos Blockchain node with a fresh devnet deployed; smart block building merged so the builder can sequence many dependent transactions into a single block.

Blockchain

LEZ performance benchmarks completed and summary document published covering minimum and recommended hardware; four research interns and two new LEZ contributors joined.

AnonComms

Stateless RLN implemented in the mix-rln-spam-protection-plugin; nim-libp2p-mix bumped to libp2p 2.0.0 and ported into dst-libp2p-test-node.

Storage

Second iteration of the hidden-services-over-Mix spec ready for review after fixing a SURB-based attack; AutoNAT v2 observed-address dialing merged in nim-libp2p.

Messaging

SDS persistency glue and a clean separation between ReliableChannelManager, MessagingClient and kernel/core landed; cross-version chat compatibility tests added to status-go.

Logos Core

Dependency interfaces work landed across the SDK stack (cpp-sdk, module-builder, plugin-qt); LIDL interface IR introduced; new logos-modules-release-tool and logos-doctest-hub repos appeared.
