6.4.4

🛜 RPC API
Validators now serve secure websocket endpoints which are used to securely and expediently accept external queries. The RPC API released in this update lays the foundation for a robust and performant query system which meets the demands of Proof of Weights, Proof of Inference and beyond.

🧾 On-Chain SSL Certificates
Rather than using a centralized certificate authority, validators (automatically) commit a hash of their self-signed SSL certificates to the chain. This allows third parties to verify their connections through certificate pinning, which increases client-server security beyond SSL alone.

📊 Prometheus Metrics
A prometheus exporter instance is now bundled into the validator by default. Key metrics such as proof verification rates and timings are logged, providing validators enhanced visibility on the health of their instances.
