June and July marked a period of focused refinement and architectural consolidation for Nomos, with significant strides made across the Bedrock layer, its supporting Services, and the broader tooling ecosystem. From finalising key specifications to deepening the implementation of critical infrastructure like Cryptarchia, Mantle, and the Blend Network, the project moved closer to production-readiness. Research-driven design updates were paired with rigorous testing and integration work, laying a strong foundation for the upcoming testnet launch and beyond.

Nomos Bedrock

June and July saw progress in the evolution of Cryptarchia, the core consensus protocol of Nomos. The Total Stake Inference v2 specification was finalised after in-depth simulation analysis. This model corrects for underestimation biases (~15%) caused by network inefficiencies and defines convergence conditions and optimal learning rates. Initial Block Download (IBD) implementation advanced substantially, with integration testing frameworks established. Further improvements to orphan block handling, storage access, and chain service refactoring increased overall reliability.

The Mantle specification, which defines Nomos' execution layer, was finalised and integrated with updated ledger structures. Channel operations such as Blob, Inscribe, and SetKeys were implemented, while foundational changes to ledger transaction processing were rolled out to support new use cases and transaction types.

Network-level work advanced with the NAT traversal state machine finalised and integrated, including support for UPnP, and early specification work on the Nomos wire format continued. The Genesis Block specification was also completed, detailing the entropy contribution process and initialization mechanics for the first block on Bedrock.

Finally, progress was made on cryptographic infrastructure, with final versions of the Trusted Setup Ceremony Specification and Common Cryptographic Components completed. Cross-platform compilation support for witness generators was implemented, and RNGs across the codebase were standardised.

Nomos Bedrock Services

Data availability infrastructure matured rapidly over the two-month period. The NomosDA specifications were improved, with clear definitions for sampling, dispersal, replication, and message structures - as well as a reward model. Optimal subnetwork sizing and quality-of-service metrics were formalised and incorporated into the finalised protocol.

Implementation efforts followed suit, with key work completed on persistent DA sessions and subnetwork assignation logic. Sampling protocol behavior was streamlined, and DA commitment distribution over QUIC-based communication streams was implemented. Membership integration with DA services was tested and merged, while HTTP endpoints for integration testing were added to support upcoming testnet deployments.

On the Blend Network, the finalised Version 1 specification was fully integrated. This included a new message encapsulation system with cryptographic validation, session clock tracking, and a refined core-edge architecture. A dedicated proxy service was introduced to manage communication between edge and core nodes. Edge service implementation was completed, and the Blend libp2p stack was refactored to align with its new architecture. Simplified message identifiers, enhanced encapsulation logic, and robustness improvements were also delivered.

Road to Production, Testnet and Tooling

Throughout this period, the team ramped up efforts to build a robust developer and node operator environment. Testing infrastructure expanded to cover IBD scenarios and orphan block handling. The Overwatch framework gained new lifecycle macros, dependency mapping via Mermaid diagrams, and status-tracking enhancements.

Looking Ahead

With many specifications now finalised and critical components integrated or nearing completion, Nomos enters a decisive stage of internal testing and external preparation. The almost fully-specified Bedrock layer and robust implementations of Bedrock Services and associated tools all signal that the network is steadily approaching public readiness. As the groundwork continues to solidify, Nomos remains focused on building a secure, efficient, and principled foundation for self-sovereign network states.
