Explore the core features and technology behind Yafu Accelerator
Yafu Accelerator fully implements the WireGuard protocol, utilizing just 1/100th of the code compared to IPsec while providing 3-5 times faster transmission speeds. The streamlined code means a reduced attack surface and enhanced security, allowing you to enjoy incredible speed without worrying about privacy breaches.
Yafu Accelerator enforces the industry's strictest no-logs policy — not recording your connection times, websites visited, IP address, or any browsing data. This policy has been independently audited by the renowned security firm Cure53, with a full report available, ensuring that every promise can be validated.
Yafu Accelerator's intelligent routing engine continuously checks the latency and load of global nodes, automatically matching you to the optimal route. With one-click connectivity, latency as low as 15ms ensures a smooth, interruption-free experience for video calls, online gaming, or 4K streaming.
Yafu Accelerator has deployed over 3000 high-speed servers across more than 80 countries and regions, including North America, Europe, Asia-Pacific, South America, and the Middle East. Each server operates in pure RAM mode, erasing all data upon reboot to eliminate the potential for data retention at the hardware level.
One Yafu Accelerator account protects your phone, computer, tablet, smart TV, and router — up to 6 devices can connect simultaneously, allowing your entire family to share a secure network without additional fees. After configuring your router, you can even protect IoT devices that don’t support accelerators.
Yafu Accelerator has a bilingual professional support team in both Chinese and English, providing 24/7 online assistance. Whether you need help with installation, connection issues, or account management, you can receive prompt, professional help via online chat or email, with an average response time of under 2 minutes.
Discover how the cutting-edge routing protocol used by Yafu Accelerator provides you with exceptional speed and security.
Yafu Accelerator has built a novel routing engine based on the WireGuard protocol. WireGuard accomplishes full accelerator functionality with approximately 4000 lines of code, while traditional IPsec requires over 600,000 lines. This streamlined code leads to a smaller attack surface, lower latency, and higher throughput. In our internal tests, the handshake speed of WireGuard is three times faster than IKEv2 and eight times faster than IPsec.
Yafu Accelerator's implementation of WireGuard uses the Noise protocol framework for key exchange, employing Curve25519 for ECDH key negotiation, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been extensively validated in academia and industry, providing forward-looking security against quantum computing attacks.
In certain network environments, WireGuard's UDP traffic may be restricted. Yafu Accelerator features built-in smart protocol switching that can automatically detect network conditions and seamlessly switch between WireGuard, IKEv2, and our proprietary obfuscation protocol, ensuring stable connectivity in any environment. The entire switching process occurs within 500 milliseconds, making it virtually undetectable by users.
Multi-layer encryption technology and a strict privacy policy comprehensively protect your digital life.
Yafu Accelerator utilizes the AES-256-GCM encryption mode to encrypt all transmitted data. AES-256 is the encryption standard approved by the NSA for protecting 'Top Secret' information. Even with the most powerful supercomputers available today, it would take billions of years to crack. A unique session key is generated for each connection, ensuring forward secrecy.
Yafu Accelerator runs its own private DNS server cluster, with all DNS queries resolved through encrypted connections, eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection, ensuring your real IP address remains concealed at all times. You can verify your protection status using the built-in leak testing tool.
Yafu Accelerator features a network kill switch that immediately cuts off all internet traffic if the acceleration connection drops unexpectedly, preventing any data from leaking unencrypted. This function supports both system-level and application-level modes: system-level mode protects all traffic, while application-level mode only protects specified applications, giving users maximum flexibility.
High-speed connections optimized for streaming and online entertainment, allowing you to enjoy exciting global content.
Yafu Accelerator's high-speed nodes are specially optimized to stably support the transmission requirements of 4K ultra-high-definition (2160p) videos. Whether it's HD movies, live sports events, or music videos, Yafu Accelerator provides a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can consistently exceed 500Mbps.
Yafu Accelerator has been specifically optimized for online gaming. Our intelligent routing engine can automatically select the lowest-latency route to game servers. In our tests, latency to Asia-Pacific game servers was as low as 10ms, and to North American servers as low as 60ms. The DDoS protection feature prevents you from falling victim to malicious attacks during gaming.
Yafu Accelerator has enabled P2P optimization on nodes in over 30 countries. We do not limit the bandwidth or speed of P2P protocols like BitTorrent while protecting your download activity from ISP monitoring and throttling through encrypted connections. The port forwarding feature can enhance seeding efficiency and support faster upload speeds.
