NPS

Roadmap

English 中文版

NPS is on a four-phase path from draft specification to formal standard. The latest suite release is v1.0.0-alpha.18, published 2026-08-15. It delivers the NPS-CR-0011 / NWP 0.21 stateful LLM context contract across all six SDKs — owner-bound context ids, create / append / fork / reset / status / release, compare-and-swap versions, atomic cancellation, NWM 0.2 discovery, and NIP 0.14 llm:context authorization — plus official NWP LLM usage telemetry with unary request_id correlation and the new NPS-LIMIT-RESOURCE code. The specification tree now carries the reviewed, unreleased alpha.19 debt-closure candidate; installable artifacts remain alpha.18.

Version convention

Tag	Meaning
`v0.x-draft`	internal draft; breaking changes allowed
`v0.x-alpha`	public preview; API not stable
`v0.x-beta`	feature-complete; external testing
`v1.0`	spec frozen; production-ready

Phase 0 — Spec Unification (2026 Q2) — ✅ done

Established the full NPS spec skeleton across all five protocols (NCP / NWP / NIP / NDP / NOP), unified the frame namespace, published the AaaS and Node conformance profiles, and released public repositories.

Phase 1 — Core Implementation (2026 Q3) — ✅ shipped

All five protocols production-ready in six reference SDKs (.NET / Python / TypeScript / Java / Rust / Go), with NIP CA Server reference deployments in all six languages. Key milestones:

NPS-RFC-0001 (NCP connection preamble), NPS-RFC-0003 (agent identity assurance levels), NPS-CR-0001 (Anchor/Bridge Node split), NPS-CR-0002 (Anchor topology queries) — all shipped
NPS-RFC-0002 (X.509 NID + ACME) prototype across all six SDKs; typed remote CA clients delivered in alpha.14
NPS-RFC-0004 (CT-style NID reputation ledger) Phase 1+2+3: SQLite + Merkle tree + STH + inclusion proofs + STH gossip federation
npsd L1 daemon with sub-NID issuance and per-NID inbox queues
Token-savings: 45.0 % CGN reduction vs REST · Wire-size: 63.6 % reduction vs JSON

Phase 2 — Ecosystem Expansion (2026 Q4) — 🚧 in progress

Adapters to MCP, A2A, and gRPC ecosystems; Tier-2 MsgPack production hardening; reference tooling.

✅ MCP, A2A, and gRPC ingress adapters packaged and published to Nexus at v1.0.0-alpha.16
✅ Tier-2 MsgPack and token-savings benchmarks published
✅ NOP orchestrator executes multi-node DAGs; Claude Desktop integration via mcp-ingress verified
✅ NDP.ResolveFrame DNS TXT resolution (nwp:// → physical endpoint) — all six SDKs
✅ Native-mode NWP serving helpers and TC-N1/TC-N2 conformance helpers delivered for SDK alpha.16
⬜ NPS Studio (visual frame debugger) + NPS Probe (conformance CLI)

Phase 3 — Ecosystem Validation (2027 Q1–Q2)

Real-world deployments, NPS Cloud CA v1.0, and the beginnings of de-facto standard status.

⬜ NPS Cloud CA v1.0 — multi-region HA, real-time OCSP
⬜ LangChain / AutoGen / CrewAI integration packages
⬜ FinTech and connected-vehicle PoCs
⬜ NIP CA Server OSS v1.0 (PostgreSQL + Web Admin UI)
⬜ Public token-savings benchmark report
⬜ GitHub stars ≥ 500

Phase 4 — Standardization (2027 Q3 onward)

Formal W3C / IETF standardization and NPS 1.0 spec freeze.

⬜ W3C WebAI Community Group proposal
⬜ IETF Internet-Draft (NCP + NWP core)
⬜ NPS 1.0 spec freeze
⬜ ISO/IEC JTC 1 evaluation
