Stylus Hardware Anchor

Reusable hardware identity verification primitive for Arbitrum Stylus. Binds ESP32-S3 eFuse silicon identifiers to on-chain execution — enabling deterministic device identity, replay-safe receipts, and firmware-governed access control. Prototype deployed on Arbitrum Sepolia. $49K USD Stylus Sprint grant application submitted.

NEXUS Phase 1.4.0

Nexus Protocol — Sovereign Edge Gateway

Universal zero-trust execution layer for DePIN hardware. Verify-then-Execute model with Cloudflare Zero Trust ingress, fail-closed Sentry perimeter, 60/30/10 economic invariant enforced at the protocol layer. 1M transaction stress test validated (0% corruption, 50–60 TPS baseline). Phase 2.0 targets peaq ID and IoTeX ioID integration.

OAP In Development

OAP — Integrity Governance Engine

Deterministic motion validation and lifecycle trust governance for mobility, robotics, and DePIN systems. Physics envelope enforcement, non-linear trust scoring, identity clone containment, adaptive checkpoint anchoring. OAP emits verifiable integrity state — partners apply economic logic. Design architecture and structural model published.
