The JX888
Bridge ASIC
At the heart of our Twin Jade™ J88 is the JX888—our proprietary PCIe-to-Multi-I/O bridge controller. This custom silicon eliminates the need for microcontrollers, providing direct, high-speed communication between your system and mining ASICs.
The JX888 is specifically engineered for cryptocurrency mining applications, offering superior performance and reliability compared to traditional ESP32/microcontroller-based solutions.
In Plain English: Most mining hardware uses a small external computer (microcontroller) to connect your mining chips to your PC. We eliminated that middleman. Our custom JX888 chip connects mining hardware directly to your computer, making it faster and simpler.

Why Direct PCIe Communication?
Here's why our direct connection approach is better than traditional mining hardware:
Traditional mining hardware relies on microcontrollers (ESP32, Arduino, etc.) as intermediaries. The JX888 eliminates this bottleneck.
How Most Miners Work (Complex)
❌ Multiple connection points slow things down
❌ External controller adds cost and complexity
❌ More components = more things that can fail
❌ Harder to diagnose problems
How Twin Jade Works (Simple)
✓ Fewer components = more reliable
✓ Direct connection = faster performance
✓ No external boxes or cables
✓ Easier troubleshooting
Superior Latency for Solo Mining
The Hash Processing Unit architecture provides significant latency advantages over traditional ESP32-based miners, especially critical for solo mining operations.
ESP32-Based Miners (Traditional)
- • External ESP32 microcontroller manages mining
- • USB networking introduces latency delays
- • Limited processing for optimization
- • Slower response to pool/network changes
- • Constrained by ESP32 capabilities
Twin Jade HPU Advantages
- ✓ Your computer's CPU manages mining (lower latency)
- ✓ Uses your computer's internet connection
- ✓ Background optimization in host CPU
- ✓ Instant response to difficulty changes
- ✓ Optimized for solo mining operations
Technology Roadmap: From Bridge ASIC to Full Silicon Independence
Our journey toward decoupling from Chinese supplier market dominance:
Phase 1: Proprietary Bridge ASIC (Complete)
JX888 eliminates dependency on ESP32 microcontrollers. First step toward sovereignty.
Phase 2: Hash Processing Unit™ Platform (Current)
Twin Jade™ J88 with Bitmain ASICs and proprietary JX888. Proving HPU™ architecture.
Phase 3: Universal Multi-Algorithm ASIC (In Progress)
Developing the world's first universal Hash Processing Unit™ ASIC - a single chip supporting SHA-256, Scrypt, Equihash, RandomX, and more. Breaks supplier monopoly AND single-algorithm limitations.
Phase 4: Open Platform Ecosystem (Future)
Fully independent technology stack with open development platform. Community-driven expansion to new algorithms and use cases.
Why this matters: The Bitcoin mining ASIC market is controlled by three Chinese companies (Bitmain, Canaan, WhatsMiner). Lucky Jade's proprietary ASIC initiative will enable miners worldwide to decouple from this monopoly, providing supply chain diversification, competitive alternatives, and open innovation.
