October was a productive and defining month for the Nomos project, marked by significant advancements in the realms of Bedrock and Blend Network development. In addition to technical progress, Nomos has begun stepping into the public spotlight with a keynote presentation at the Dark Prague conference. This presentation highlighted Nomos’ vision and ongoing advancements in the realms of privacy and resilient architecture, echoing the latest developments described below.
Nomos Bedrock
Research
The cryptography research team continued its comprehensive audit process, documented in the Nomos Cryptography Audit, which consolidates months of review. The Service Declaration Protocol (SDP) and Service Reward Distribution Protocol (SRDP) specifications were updated with new fields and logic for session tracking information, locked note identifiers, and snapshot computation. These refinements allow for clearer rules for rewards and activity proofs.
Development
Development across Nomos Bedrock focused on integrating new protocol specifications into core components. In Cryptarchia, work progressed on block reconstruction, enabling nodes to reconstruct blocks from peer proposals using locally available transactions. The time service API was implemented for slot queries, and conditional blob validation was introduced to streamline block verification during synchronisation. In the ledger and transaction pipeline, several key milestones were reached. Service membership tracking was successfully migrated into the ledger to simplify reward distribution, and invalid transaction handling was introduced to prevent disruptions to block production. The SDP saw major functional development, including an HTTP API for Declare, Withdraw, and Active messages, along with scaffolding for reward processing.
Nomos Bedrock Services
On the services layer, both the Blend Network and Data Availability (NomosDA) made substantial integration progress. The Blend Network group completed a statistical mechanics analysis for scenarios with multiple sender nodes, showing that the best anonymity is achieved with the most random initial distribution is used. The Blend Protocol implementation was updated to include support for epoch and session transitions and ensuring resilience through service recovery logic. For NomosDA, new features allowed non-member peers to participate in data dispersal, improving the decentralisation of the network.
Road to Production, Testnet, and Tooling
The testing and tooling ecosystem also matured significantly in October. The circuits repository was restructured to produce single bundled artifacts per target, simplifying release management for proving and verification keys. Integration testing expanded to cover Mantle channel and SDP operations, and the Nomos block explorer proof-of-concept reached completion, offering a live visualization of blocks and transactions.
Conclusion
October 2025 represents an important chapter in the Nomos journey, demonstrating the project's ability to deliver on both technical sophistication and public engagement. From foundational protocol updates in Cryptarchia, to service-layer innovations in Blend and NomosDA, the month showcased a cohesive push toward production-readiness. The completion of critical tooling infrastructure, coupled with expanded integration testing and the debut of the block explorer, signals that Nomos is transitioning from research and development into a phase where real-world deployment becomes tangible.
