Logos Collective Weekly Summary

Post-Quantum

• Blend post-quantum primitive candidates document restructured into a four-phase migration plan, with benchmark numbers split into a separate document — doc
• Benchmark code updated (in-review) — logos-blockchain-pocs #112

Cryptarchia

• Proof of Leadership handling for the degenerate case where a note value far exceeds total stake merged into the spec — logos-lips #362
• Compressed Block Proposal RFC updated for the new Mantle transaction hashing algorithm — doc

Session Removal

• "Remove Concept of a Session" RFC migration completed — everything migrated, with many migration issues found and corrected along the way; RFC under review — branch

Total Stake Inference

• Total-delay formula derived for a message routed over k hops through the Blend network: average delay grows as O((k+1)·log N_B) + O(k+2) + O(log N), with sampling code implemented — doc
• "Referenced-Block Visibility for Total Stake Inference" report significantly revised with a new experiment suite: matched Poisson-delay baselines, required-window sweeps under native and Poisson delay, high-delay threshold runs near the theoretical boundary, long-horizon confirmation runs, and m_max sensitivity analysis showing that raising m_max from 2 to 4 removes most high-delay visibility loss — doc

Permissionless Channel Sequencing

• Sequencer design reworked after the previous approach fell apart: v5 design based on stake-gated registration (fixed stake amount, register K times for K round-robin positions), an SDP-shaped lifecycle, round-robin turns with a posting timeout, and an owner-gated bond kept off the channel-withdraw path — doc
• Channel Proof of Stake participation spec submitted with test vectors (in-review) — logos-lips #364; EdDSA multiverification factored out and channel-config validation enforced (in-review) — logos-lips #367

Cross-Zone Sequencing

• Cross-Zone Atomic Coordination Protocol specification refined with a Security Analysis section covering abort scenarios at each protocol phase, and a Channel Tip Invalidation scenario with two mitigation strategies (soft channel lock and state pre-computation) — doc

Anonymous Communications

• Communication-network and adversarial models built and integrated into a prototype simulation framework with reproducible experiments: broadcast latency and scaling analysis, a baseline global passive adversary plus a latency-aware partial-monitoring adversary, and validated privacy metrics for sender anonymity, stake privacy, timing leakage, resilience, and intersection attacks — doc
• Pareto stake-distribution shape parameter calibrated against real Cardano data — doc; adversary model and measures of anonymity formalised — doc

Blend

• Invalid peers cleaned from the Kademlia routing table immediately when they advertise a mismatched peer ID — logos-blockchain #2996
• Connectivity-maintenance revision started for Blend peer banning (WIP) — doc

Security Audit

• NomBoundedVec and NomArray removed, with NomEncode/NomDecode implemented directly on BoundedVec and arrays — #3023
• Derive macros added for the traits, with a mandatory encoding fixture per type run as a unit test to catch wire-format breakage — #3025

Node

• Well-known deployment structure refactored to one deployment per binary — #3001; deployment file structure reworked for templates and multiple environments (in-review) — #3034; batch Groth16 verification revamp (in-review) — #3026
• Wallet balances now track channel-withdraw outputs — #2997; wallet transaction ordering fixed — #3000; note-unlock events emitted when the note is actually unlocked — #3017
• Mempool lookup preserves requested transaction order for block-proposal reconstruction — #3010; block data stored atomically (body, parent link, events, immutable index) — #3022; chain recovery falls back gracefully when the recovered tip is missing from storage — #3024; unused transaction-selector wiring removed — #3015
• Orphan downloader gained a negative cache — #3033; chain-sync block provider batch size made configurable — #3035; scalable Initial Block Download opened (WIP, draft) — #3019

• Manual wallet balance reads sped up in end-to-end manual-control tests — #3030

Zone SDK

Logos Core

• FFI error management improved: errors returned as part of a Result so handling is delegated to the module/UI — #3036, integrated in the module — logos-blockchain-module #47
• Transaction ids packed on JSON serialization for the C bindings, exposing explorer-ready ids — #3011; leftover legacy circuits removed — #3020; writable-path handling fixed for core modules — #3027, logos-blockchain-module #45

LEZ Module

• Mnemonic-based wallet FFI merged — logos-execution-zone #518; generic transactions exposed through the module merged — logos-execution-zone-module #29, with further module updates — #31, #34
• Wallet FFI labels opened (in-review) — #577; PDA account-id generation through the FFI started (WIP) — #582

Wallet UI

• Bridge tab merged in the wallet UI — logos-execution-zone-wallet-ui #20 with its module counterpart — logos-execution-zone-module #27

Accounts

• Viewing-key/ciphertext binding fix for shared accounts finalized for review (in-review) — #550; ephemeral-secret-key generation hardening opened (in-review) — #569
• Private-transaction data-leakage issues filed — #560, #561, #562, #572, plus improved view-tag semantics — #573 and a chained-calls privacy concern relevant to flash loans — #574
• Note-order obfuscation drafted (WIP, draft) — #564

Explorer

• Explorer and indexer packages bundled and live on the modules-release repo — logos-modules-release #6, with the indexer's sync status (Syncing / Caught Up / Failed) now surfaced in the main window
