# Technology Stack & Protocols

* QUIC Protocol: High-speed, low-latency, multiplexed encrypted connections with NAT traversal.
* Rust: Memory-safe, efficient, zero-copy data transmission for throughput optimization.
* Intelligent DNS & Routing: Ensures shortest path and lowest latency between consumer and destination.
* Blockchain (U2U Subnet): DAG-based, EVM-compatible chain with Helios Consensus for settlement and governance.
