  ## Features
  
 - **Decentralized**: No need to rely on centralized services, nodes are equal and independent.
 - **Safe**: Use WireGuard protocol to encrypt data.
+- **High Performance**: Full-link zero-copy, with performance comparable to mainstream networking software.
 - **Cross-platform**: Supports MacOS/Linux/Windows, will support IOS and Android in the future. The executable file is statically linked, making deployment simple.
 - **Networking without public IP**: Supports networking using shared public nodes, refer to [Configuration Guide](#Networking-without-public-IP)
 - **NAT traversal**: Supports UDP-based NAT traversal, able to establish stable connections even in complex network environments.

 - **Smart Routing**: Selects links based on traffic to reduce latency and increase throughput.
 - **TCP Support**: Provides reliable data transmission through concurrent TCP links when UDP is limited, optimizing performance.
 - **High Availability**: Supports multi-path and switches to healthy paths when high packet loss or network errors are detected.
+- **IPv6 Support**: Supports networking using IPv6.
