Logos Blockchain Weekly Update - 2026-07-13

blockchain:highlights

• Tokenomics enabled on master (baselayer only): transaction fees end-to-end #3070, fund endpoint #3100, non-zero-gas tests #3083
• Scalable Initial Block Download merged: requests fan out across discovered peers #3019
• Channel operations merged in Nimbos nimbos#100
• Proof of Leadership post-quantum proving findings published doc

blockchain:bedrock:research

• blockchain:bedrock:research:post-quantum

  • Proof of Leadership post-quantum proving findings summary published, based on the cross-scheme benchmark results doc
  • Post-quantum primitive benchmark dashboard published dashboard

• blockchain:bedrock:research:mantle

  • Multiple Ed25519 threshold verification factored out of the Mantle spec, with configuration-threshold validation added logos-lips#367
  • SDP Per-Service Uniqueness RFC opened: provider_id and zk_id unique within a service (in-review) logos-lips#371

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

  • “Referenced-Block Visibility for Total Stake Inference” report restructured with an explicit inference-feedback evaluation layer and comparisons among known-stake, chain-only, and reference-enhanced inference; references substantially improve denominator calibration and reduce chain-only over-emission and fork waste doc
  • New network-delays model implemented and tested in Python, with a new results section added to the report doc

• blockchain:bedrock:research:cross-zone-sequencing

  • Costly Abort Mechanism drafted: on-chain bond protocol steps (deposit timing, on-chain lock window, fund recovery under normal completion and abort), plus a survey of timed-lock puzzles and timed commitments for penalizing non-responsive parties in the off-chain protocol doc

• blockchain:bedrock:research:anonymous-communications

  • Single-path mix model specified end to end, with a sender-set stake estimator and closed-form latency and bandwidth overheads validated against the simulator doc
