Logos Blockchain Weekly Update - 2026-03-23 §

blockchain:highlights §

• Total Stake Inference: counting factor q now derived mathematically from network assumptions instead of fitted empirically, strengthening the theoretical foundation
• Mantle transaction hash optimization RFC: significantly speeds up transaction hashing for large inscriptions
• Blend: multiple stability fixes improving session rotation reliability and node resilience
• Testing framework: refactored into a reusable library, enabling use beyond internal test harness
• Logos Execution Zone: sequencer code cleanup, Keycard-compatible key protocol, and indexer performance improvements
• Nimbos: first bindings merged, starting networking implementation

blockchain:bedrock:research §

• blockchain:bedrock:research:total-stake-inference

  • Derived counting factor q from a propagation-and-competition model, replacing empirical fitting with a mathematical derivation; validated against blockchain simulations; connected to stability analysis of stake inference dynamics draft
  • Complete rewrite of “Total Active Stake Inference under Stake Privacy” paper paper; started Total Stake Inference spec draft spec

• blockchain:bedrock:research:cryptarchia

  • Checkpoint-based fast bootstrapping RFC and Cryptarchia Bootstrapping & Synchronization spec v2 RFC, spec
  • Cleaned up EmPoWering document into shareable form doc
  • Mantle transaction hash optimization RFC RFC

• blockchain:bedrock:research:tokenomics

  • Refactored tokenomics documents doc

blockchain:bedrock:eng §

• blockchain:bedrock:eng:blend

  • Fixed Proof-of-Quota nullifier: distinct nullifier per winning Proof-of-Leadership without changing core node behavior
