S.U.T.R.A.

Secure Unjammable Tactical Resilient Array

S.U.T.R.A. is a decentralized, fault-tolerant coordination network and consensus simulator for Unmanned Aerial Vehicles (UAVs) operating in GNSS-denied and heavily contested electronic warfare (EW) environments.

By unifying edge-computing consensus algorithms with Web3 cryptographic identity, S.U.T.R.A. guarantees spatial swarm integrity even when significant portions of the network are jammed, spoofed, or compromised

🏗 The Architecture of Resilience

The system is built upon three fundamental pillars of decentralized security:

1. SwarmRaft Consensus

A customized implementation of the Raft consensus algorithm optimized for spatial recovery. When nodes experience GNSS spoofing, the network utilizes a 6-step workflow (Sense, Inform, Estimate, Evaluate, Recover, Finalize) to dynamically substitute faulty telemetry with peer-range triangulated estimates, strictly enforcing n ≥ 2f + 1 Byzantine fault tolerance.

2. Cryptographic MANET

An asynchronous peer-to-peer Mobile Ad-hoc Network (MANET) operating over UDP sockets. It enforces absolute cryptographic semantic integrity using standard secp256k1 (ECDSA) to sign and verify every single coordination packet. Unauthenticated or malformed payloads are immediately dropped to prevent Byzantine injection and replay attacks.

3. Proof of Physical Work (PoPW)

An on-chain Sybil-defense mechanism deployed via Solidity smart contracts. Drones must provide authorized cryptographic proofs of physical waypoint arrival to claim "Voting Power" (DVP). This ensures that network authority is inextricably linked to kinetic reality, structurally preventing remote attackers from spawning virtual nodes.

🚀 Quick Start

1. Launch the Next.js Dashboard

Navigate to the dashboard directory and start the frontend Command Center interface:

cd dashboard
npm install
npm run dev

Access the dashboard at http://localhost:3000.

2. Run the Python Swarm Simulation

Ensure you have Python 3.9+ installed to run the backend consensus simulator.

python -m venv venv
.\venv\Scripts\activate
pip install numpy cryptography

3. Deploy Local Foundry Contracts

To test the PoPW token economy and cryptographic identity layer:

cd contracts
forge build
anvil
