Fractal Bitcoin is creating waves in the crypto space with its innovative approach to Bitcoin's ecosystem. Developed by the Unisat team—known for supporting inscription runes for over a year—Fractal introduces a native Layer 2 solution. This has sparked massive community engagement, with 6 million interactive addresses and projects racing to lead the ecosystem. BTC miners are even diverting hash power to mine FB (Fractal Bitcoin), marking the most significant multi-stakeholder synergy since Ordinals.
Unique Mining Mechanism
Fractal Bitcoin features a hybrid mining model:
- 1/3 of blocks support dual mining via pooled mining, ensuring chain security.
- Existing BTC hash power can mine both BTC and FB simultaneously.
Our team (@SoloFractal) conducted extensive tests from August 14 using:
- High-end PCs (i9/4090)
- Small-scale miners (0.3–4TH/s)
- Industrial rigs (S21/S19)
Here’s the breakdown:
1. Mining with High-End PCs (i9/4090)
Early adopters speculated PCs could mine FB due to initially low network hash rate. Our tests revealed:
- CPU Miner: Failed to initialize.
- GPU Miner (CGMINER): Achieved only 10GH/s at 200–300W power draw.
Verdict: While possible, PCs are inefficient due to:
✔ High electricity costs
✔ Overwhelming competition from ASICs (e.g., S19)
✔ Noise/heat issues (even 4090 GPUs run loud)

2. Small-Scale Miners (0.3–4TH/s)
Following a 500GH/s miner’s solo BTC block win in July, small miners gained traction. Our FB tests showed:
| Miner | Results (24hr) | Rewards |
|---|---|---|
| 320G/1T LuckyMiner | 2 blocks mined | 50 FB |
| 4T Avalon3 | 4 blocks mined | 100 FB |
Advantages:
✔ Affordable ($60–$300)
✔ Home-friendly (book-sized, 14–140W, 30–36dB noise)
✔ Ideal for散户 (retail miners)
3. Industrial Mining Rigs (S21/S19)
Connected to @SoloFractal’s pool, these dominated:
- 60% of blocks mined in 24 hours.
Caveats:
✖ Banned in China
✖ Requires 3000W power, loud operation (>75dB)
✖ Needs overseas hosting (mainnet participation recommended)
4. Joining a Mining Pool
@SoloFractal operates Fractal Bitcoin’s largest SOLO mining pool, controlling 60–70% of network hash rate.

FAQ Section
Q1: Can I mine FB without ASICs?
A: Technically yes (via PC/small miners), but ASICs yield 1000x+ efficiency.
Q2: Is FB mining profitable vs. BTC?
A: Early-stage rewards are higher, but monitor electricity costs and network difficulty.
Q3: How to start with small-scale miners?
A: Purchase plug-and-play devices (e.g., LuckyMiner), connect to pools like @SoloFractal.
