Logos Blockchain Weekly Update - 2026-09-21

blockchain:highlights

• Node 0.3.0-rc.3 published for internal devnet testing release
• Logos Execution Zone sharded program state merged #835
• Logos Execution Zone ciphertext padding merged: every private note is a uniform 512 bytes on chain #630
• Nimbos Proof of Quota zk verifier and queue-driven block processor merged nimbos#193, nimbos#194

blockchain:bedrock:research

• blockchain:bedrock:research:cryptarchia

  • Hierarchical key management for one-time keys RFC opened, bumping the Wallet Technical Standard to 1.2.0 (in-review) logos-lips#452
  • Off-chain inscription bodies on Logos Storage RFC drafted: Logos Storage acting as a pseudo Data Availability network (draft) logos-lips#454

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

  • Permanent forks observed on testnet 0.2.2 investigated: chain sync can fail to recover from a persistent fork despite repeatedly discovering the taller branch #3577

• blockchain:bedrock:research:empowering

  • Modelling framework built to assess whether tokenless newcomers can reach the Blend balance requirement before mined tokens unlock after one year, extended to multiple newcomers and capitalised competitors; numerical experiments identify leadership revenue and the finite mining pool as the key constraints doc

• blockchain:bedrock:research:permissionless-channel-sequencing

  • User ownership of channel funds proposed: sequencer power over funds removed and handed back to users doc
