DCRE Mesh
Triangulation-Free Communication Protocol with AI Workflow Governance - A novel mesh networking system using lattice transforms for privacy-preserving, location-independent communication and deterministic AI inference verification.
🎯 What is DCRE?
DCRE (Dynamic Cellular Routing Evolution) is a communication protocol that achieves triangulation-free messaging and provides deterministic verification for AI workflows.
Two Core Use Cases
┌─────────────────────────────────────────────────────────────────────────────┐
│ 1. PRIVACY-PRESERVING COMMUNICATION │
│ Messages verified without revealing sender, receiver, or routing paths │
├─────────────────────────────────────────────────────────────────────────────┤
│ 2. AI WORKFLOW GOVERNANCE │
│ Tamper-evident audit trails for LLM inference with policy enforcement │
└─────────────────────────────────────────────────────────────────────────────┘Key Innovations
| Feature | Traditional | DCRE | |---------|-------------|------| | Message Identity | IP Address | Perturbation Hash | | Verification | Trust/PKI | Lattice Replay | | Routing | IP Tables | State Evolution | | Privacy | TLS (transport) | Intrinsic (protocol) | | AI Audit | Log Files | Lattice Fingerprints | | Determinism | Hope | Cryptographic Proof |

🚀 Quick Start
Installation
npm install @dcre/mesh30-Second Demo: Real-Time Sync
import { DCREAdapter } from '@dcre/mesh';
// Create two clients
const alice = new DCREAdapter({ userId: 'alice' });
const bob = new DCREAdapter({ userId: 'bob' });
await alice.init();
await bob.init();
// Join same channel
await alice.joinChannel('chat-room');
await bob.joinChannel('chat-room');
// Alice sends, Bob receives
bob.on('message_received', ({ message }) => {
console.log('Bob received:', message.content);
});
await alice.send('chat-room', 'Hello Bob!');30-Second Demo: AI Governance
import { AIGovernancePlugin, GovernancePresets } from '@dcre/mesh';
// Create governance with standard policies
const governance = new AIGovernancePlugin(GovernancePresets.standard());
// Wrap your AI calls
const result = await governance.wrapInference(
{ model: 'gpt-4', prompt: 'Explain quantum computing' },
async (params) => {
const response = await openai.chat.completions.create({
model: params.model,
messages: [{ role: 'user', content: params.prompt }]
});
return {
response: response.choices[0].message.content,
usage: { input: response.usage.prompt_tokens, output: response.usage.completion_tokens }
};
}
);
console.log('Response:', result.response);
console.log('Approved:', result.approved);
