Logos Blockchain Weekly Update - 2026-02-23 §

blockchain:highlights §

• Performed 3 Devnets: 0.1.3-0.1.5 multiple Consensus, Blend and NAT fixes
• DA sampling analysis: current parameters secure against encoder subnetwork control attack
• Zone-SDK: journal log support for sequencer replayability and audit
• Testing framework extended with external network connection modes (allowing us to run scenarios against live devnets/testnets)
• SQLite zone demo REPL MVP ready (demoed in Team Update)
• CLI node journey documented

blockchain:bedrock:research §

• blockchain:bedrock:research:cryptarchia

  • Continued refining TSI draft: addressed all reviewer comments, included updated simulations and plots draft
  • Started “Total Active Stake Inference under Stake Privacy” paper draft
  • EmPoWering the Consensus cleaned up: tighter PoW-PoQ coupling rejected for more loose assumptions validating only PoW difficulty doc
  • Second review of DSE Specs: machinery looks good but missing solid parameter justification doc
  • First RFC for fast bootstrap via checkpoints: skip body validation for blocks deeper than first block of previous epoch, verify headers and apply fork choice rule, include state commitment at epoch boundaries RFC
  • Specs/RFC pages update prepared, paused as it may be superseded by lip.logos.co doc

• blockchain:bedrock:research:da:sampling

  • Subnetwork control by encoder analysis: calculations with current DA parameters show no issue for this attack scenario analysis
  • Estimated upper bound on wasted blocks: very small if available columns >= K+Delta, but very large in the “grey zone” analysis

• blockchain:bedrock:research:da:private-da

  • Private DA research continued with new additions to document notes
