Nomos Weekly Update - 2025-11-10 §

Nomos Bedrock §

Research §

• Cryptarchia:

  • Areon: Latency-Friendly and Resilient Multi-Proposer Consensus paper draft improved with all sections updated and reviewed by Marcin, addressing multiple review rounds for sections 2 and 4
  • Section 6 revision with improved readability of throughput calculation subsection

• Cryptography:

  • ZODA Implementation Details reference implementation reviewed and documented in detail for NomosDA v2
  • Cryptography audit open issue resolved
  • ZKVM comparison updated with new measures for hashing and proof recursion

• SDP Specifications:

  • Active message simplified to disregard trailing bits in opinions vector and skip validation of self-positive opinions
  • Blend message processing description improved for clarity and compliance with edge case where node is subsequent recipient of decrypted message

• Blend Network:

  • Blend Protocol specification updated with clarifications on data, processed, and cover message generation, queuing, and release logic
  • Statistical mechanics of anonymous communication analysis of k sender nodes system completed showing maximum sender anonymity achieved when time-interval graph is connected
  • Information-theoretic approach to control systems review completed with relation between controllability/observability and AC systems anonymity

Development §

• SDP, Ledger and Transaction Processing:

  • Replace mock mempool with real implementation in SDP service merged
  • Remove unused SDP service backend merged
  • Multiple sessions in historic sampling API improvements
  • Session change fallback to historical sampling for edge case when session changes before sampling starts
  • DA rewards implementation merged
  • ZkSign as proper PKCS library with SecretKey/PublicKey structs and ZK_DEV_MODE support
  • Drop DummyZkSignatures with real signatures everywhere and wallet-KMS integration for ZkSig signing
  • Use KMS in tests preparation for local node joining testnet with ZK ID and ed25519 keys
  • Fix tests imports after merge merged
  • Serialize blob and session hashmap as vec merged
  • Minor comment fix merged

• Cryptarchia Core:

  • Sampling service subscription to mempool with subscription-based approach replacing triggered sampling

Nomos Bedrock Services §

Development §

• Blend Network:

  • Separate message scheduler for old session bug fix
  • Collect old session tokens correctly bug fix

• Data Availability:

  • DA minimum session members number merged preventing DA operations with insufficient session members
