OSVM's unique three-layer security model provides unparalleled protection:
|
🔹 Unikernels (50KB)
|
🔹 MicroVMs (5MB overhead)
|
|
🔹 Zero-Trust Networking
|
🔹 Hardware Security

# Verify installation
osvm --version# Deploy a local RPC node (development)
osvm rpc local
# Your RPC node is now running on http://localhost:8899# Isolation infrastructure provides the foundation for zero-downtime deployments
# Full production commands coming in Phase 4!
# For now, explore the isolation API directly:
cd examples/
cargo run --example firecracker_demo # See MicroVM deployment
cargo run --example mcp_integration_demo # See unikernel deployment
# Traditional deployment (available now):
osvm rpc devnet # Start real devnet validatorComing in Phase 4: osvm deploy-rpc and osvm update-rpc commands with full hot-swap integration.

Scenario: RPC node compromised
| Traditional System | OSVM System |
|---|---|
| ❌ Can access validator | ✅ Isolated in MicroVM |
| ❌ Can read /proc | ✅ No access to host |
| ❌ Can exploit kernel | ✅ Separate kernel |
| ❌ Can pivot | ✅ Cannot forge certs |
| Result: Full compromise | Result: Contained |

// Update RPC node from v1.16 to v1.17 with ZERO downtime
orchestrator.update_component(rpc_v116_id, rpc_v117).await?;
// What happens:
// 1. Start new v1.17 MicroVM (125ms boot)
// 2. Run health checks (2-10s)
// 3. Shift traffic atomically (<100ms)
// 4. Drain old connections (60s background)
// 5. Stop old v1.16
//
// Total user downtime: 0ms ✨
// Automatic rollback if health checks fail// Traditional network: 5-50ms latency
rpc_node.send_to_validator(tx).await; // 5-50ms
// OSVM vsock: 0.1-0.5ms latency
vsock_manager.send(rpc_cid, validator_cid, tx).await; // 0.3ms
// 16-166x faster! 🚀Health check detects failure (30s max)
