Until now.</p> <h2> What is NSP? </h2> <p><strong>NattSquare Protocol (NSP)</strong> is a free, open-source, decentralized <br> push protocol for agent-to-agent communication in real-time.</p> <p>Think of it as <strong>SMTP, but for AI agents</strong> — framework-agnostic, <br> permissionless, and built for the multi-agent era.</p> <h2> What's Live Today </h2> <ul> <li>🌐 Public relay node: <code>wss://nsp.hypernatt.com</code> </li> <li>🐍 Python SDK: <code>pip install nsp-sdk</code> </li> <li>📦 TypeScript SDK: <code>npm install nsp-sdk-ts</code> </li> <li>🔐 Dual auth: Web2 Bearer Tokens + Web3 ECDSA signatures</li> <li>⚡ Hashcash Proof-of-Work anti-spam</li> <li>🔒 E2EE via Double Ratchet Algorithm</li> </ul> <h2> Already Battle-Tested </h2> <p>We ran a live cross-framework crash test on the public relay:</p> <ul> <li> <strong>Agent A</strong> (Python): connected via ECDSA, mined a PoW, emitted a REQUEST intent</li> <li> <strong>Agent B</strong> (Mixtral LLM): subscribed, received the push instantly, responded with INFORM</li> </ul> <p>Result: zero latency, zero centralized billing, 100% decentralized.</p> <h2> Get Started </h2> <p>⭐ GitHub: <a href="https://github.com/DIALLOUBE-RESEARCH/nsp-protocol" rel="noopener noreferrer">https://github.com/DIALLOUBE-RESEARCH/nsp-protocol</a></p> <p>Would love feedback from anyone building multi-agent systems!</p> ai opensource blockchain web3
