Founder & Lead Engineer @ Orthonode Infrastructure Labs
Building deterministic physical verification infrastructure for autonomous systems and decentralized networks.
Infrastructure engineer specializing in Rust, blockchain protocols, and embedded systems. Founder of Orthonode Infrastructure Labs — building the cryptographic trust layer for DePIN hardware.
Three active protocols under development:
| Protocol | What It Is | Status |
|---|---|---|
| SHA — Stylus Hardware Anchor | Cryptographic hardware identity binding for Arbitrum Stylus. Binds ESP32-S3 eFuse silicon IDs to on-chain execution. | Prototype live on Arbitrum Sepolia |
| Nexus Protocol — Sovereign Edge Gateway | Zero-trust edge execution layer for DePIN hardware. Verify-then-Execute model, fail-closed Sentry, 60/30/10 economic invariant. | Phase 1.4.0 active · 1M TX stress test validated |
| OAP — Integrity Governance Engine | Deterministic motion validation and lifecycle trust governance for mobility, robotics, and DePIN systems. | In development · architecture published |
| Metric | Value |
|---|---|
| Gas / receipt (batch N=50, amortized) | 12,523 gas |
| Gas / single verification | 118,935 gas |
| Test vectors validated | 10,000+ |
| Keccak-256 parity | 100% |

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 without centralized intermediaries.
- Prototype: Deployed on Arbitrum Sepolia
- Gas (amortized): 12.5k gas/receipt at N=50 batch
- Test coverage: 10,000+ vectors, 100% Keccak-256 parity
- Grant: $49,000 USD application submitted to Stylus Sprint (pending)
- License: MIT
Universal zero-trust execution layer for DePIN hardware. Moves verification to the edge — validating physical sensor integrity and hardware context before any protocol-level execution occurs.
- Phase 1.4.0: Cloudflare Zero Trust ingress, fail-closed Sentry, SQLite WAL vault
- Stress tested: 1M transactions, 0% corruption, 50–60 TPS baseline on edge hardware
- Economic invariant: 60/30/10 split enforced at Brain level — immutable
- License: Apache 2.0
Deterministic motion validation and lifecycle trust governance for mobility, robotics, and DePIN systems. OAP emits verifiable integrity state; partners apply economic logic.
- Design: Physics envelope enforcement, non-linear trust scoring, identity clone containment
- Status: Architecture and structural model published, product in development
