Explore the core features and technology behind Zhifeiji Accelerator
Next-Gen WireGuard Protocol
Zhifeiji Accelerator fully adopts the WireGuard protocol, which consists of just 4000 lines of code—1/100th of IPsec—yet delivers 3-5 times the transmission speed. The streamlined code leads to a smaller attack surface and heightened security, allowing you to enjoy exceptional speed without worrying about privacy breaches.
Audited No-Logs Policy
Zhifeiji Accelerator implements the industry's strictest no-logs policy—no recording of your connection times, websites visited, IP addresses, or browsing data. This policy has been independently audited by the renowned security firm Cure53, and a comprehensive report has been published, ensuring every commitment can withstand scrutiny.
Millisecond Intelligent Connections
Zhifeiji Accelerator’s intelligent routing engine continuously monitors global node latency and load conditions, automatically selecting the optimal route for you. With one-click connectivity and latency as low as 15ms, whether it's video conferencing, online gaming, or 4K streaming, you'll enjoy a smooth experience without interruptions.
Node Coverage in Over 80 Countries
Zhifeiji 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, ensuring that all data is wiped upon reboot, effectively eliminating any possibility of data retention at the hardware level.
One Account, 6 Devices Simultaneously Online
With a single Zhifeiji Accelerator account, you can protect your smartphone, computer, tablet, smart TV, and router—up to 6 devices connected simultaneously, allowing your whole family to share a secure network without any extra charges. Once configured on your router, it can also protect IoT devices that don't support accelerators.
24/7 Professional Customer Support
Zhifeiji Accelerator features a bilingual customer support team, offering 24/7 assistance in both Chinese and English. Whether it’s installation, connectivity issues, or account management, you can get instant, professional help via online chat or email, with an average response time of under 2 minutes.
In-Depth Analysis of Protocol Technology
Discover how the cutting-edge connection protocols used by Zhifeiji Accelerator provide you with unmatched speed and security.
Core Architecture of WireGuard
Zhifeiji Accelerator has built a new connection engine based on the WireGuard protocol. WireGuard achieves full accelerator functionality with around 4000 lines of code, while traditional IPsec requires over 600,000 lines. The more concise code results in a smaller attack surface, lower latency, and higher throughput. In our internal tests, WireGuard's handshake speed is three times faster than IKEv2 and eight times faster than IPsec.
Noise Protocol Framework Encryption
Zhifeiji Accelerator's implementation of WireGuard utilizes 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 both academia and industry, providing proactive security guarantees against quantum attacks.
Intelligent Protocol Switching
In certain network environments, WireGuard's UDP traffic may be restricted. Zhifeiji Accelerator has a built-in intelligent protocol switching feature that automatically detects network conditions and seamlessly transitions between WireGuard, IKEv2, and our proprietary obfuscation protocols, ensuring stable connections in any setting. The entire switching process is completed within 500 milliseconds, almost imperceptibly to users.
Multi-Hop and split routing
Zhifeiji Accelerator supports Multi-Hop connections, allowing data to be relayed through two or more acceleration servers, providing an extra layer of privacy for users who require extreme anonymity. Additionally, the split routing feature lets you choose which applications access the accelerator and which connect directly to the local network, achieving the best balance of performance and security.
Encryption and Privacy Protection
Multi-layer encryption technology and a stringent privacy policy fully protect your digital life.
AES-256-GCM Encryption Standard
Zhifeiji Accelerator uses AES-256-GCM encryption mode to secure all transmitted data. AES-256 is the same encryption standard approved by the NSA for protecting 'top secret' information. Even with the most powerful supercomputers, it would take billions of years to crack. Each connection generates a unique session key, ensuring forward secrecy.
DNS Leak Protection
Zhifeiji Accelerator operates its own private DNS server cluster, ensuring all DNS queries are resolved through an encrypted connection, eliminating the risk of DNS leaks. We also include WebRTC and IPv6 leak protection, ensuring your real IP address is never exposed. You can verify your protection status anytime with the built-in leak testing tool.
Kill Switch
Zhifeiji Accelerator's Kill Switch feature can immediately cut off all internet traffic if the acceleration connection unexpectedly drops, preventing any data from leaking in an unencrypted state. This feature supports both system-level and application-level modes: the system-level mode protects all traffic, while the application-level mode only protects specified applications, giving users maximum flexibility.
RAM-Only Pure Memory Servers
All of Zhifeiji Accelerator's 3000+ servers operate in pure RAM mode. This means there are no hard drives present; all data is processed solely in memory. Upon each server reboot, all data is completely cleared. Even if servers are physically seized, no user data can be extracted. This represents the highest level of data protection standards in the industry.
Streaming and Entertainment Optimization
High-speed connections optimized for streaming and online entertainment, allowing you to enjoy global content seamlessly.
4K Ultra HD Streaming Support
Zhifeiji Accelerator's high-speed nodes are specially optimized to consistently support the demands of transmitting 4K ultra HD (2160p) videos. Whether it's high-definition movies, live sports events, or music videos, Zhifeiji Accelerator ensures a stable, smooth, and buffer-free viewing experience. Under gigabit broadband, connection speeds can remain consistently above 500Mbps.
Gaming Acceleration and Low Latency
Zhifeiji Accelerator is specially optimized for online gaming. Our intelligent routing engine automatically selects the route with the lowest latency to game servers. In our tests, connecting to Asia-Pacific game servers has achieved latencies as low as 10ms, and to North American servers as low as 60ms. The DDoS protection feature prevents malicious attacks during your gaming sessions.
P2P and Torrent Download Optimization
Zhifeiji Accelerator has enabled P2P optimization features on nodes in over 30 countries. We do not limit bandwidth or speeds for P2P protocols like BitTorrent, while also protecting your download activities from ISP monitoring and throttling through encryption connections. Port forwarding functionality enhances seeding efficiency, supporting faster upload speeds.
Smart Content Acceleration Technology
Zhifeiji Accelerator's proprietary SmartRoute technology intelligently identifies the type of content you are accessing and automatically selects the most optimized transmission path. It switches to streaming-optimized nodes when watching videos, large bandwidth nodes for downloading files, and prioritizes low-latency nodes for browsing. The entire process is fully automated, requiring no manual intervention.
