With Ethereum's transition to Proof of Stake (PoS), GPU miners are exploring alternative Proof of Work (PoW) coins like Kaspa (KAS). This guide covers everything you need to know about mining Kaspa using NVIDIA and AMD GPUs, including solo mining, pool mining, and dual mining with Ethereum Classic (ETC).
Key Takeaways
- Algorithm: kHeavyHash (core-intensive, energy-efficient).
- Best GPUs: RTX 3090 (1 GH/s), RX 6900 XT (1.04 GH/s), and other high-core cards.
- Mining Options: Solo, pool, or dual mining (e.g., ETC + KAS).
- Profitability: Use calculators like WhatToMine to estimate earnings.
What Is Kaspa?
Kaspa is a fast, scalable PoW cryptocurrency using the GHOSTDAG protocol, enabling parallel blocks and instant transactions. Key features:
- Block time: 1 second.
- Max supply: 28.7 billion KAS (deflationary halving yearly).
- Decentralized: No premine, fair launch.

Mining Hardware Requirements
Best GPUs for Kaspa
| GPU Model | Hashrate (MH/s) |
|-------------------|-----------------|
| NVIDIA RTX 3090 | 1,000 |
| AMD RX 6900 XT | 1,040 |
| RTX 3080 Ti | 850 |
| RX 6800 XT | 850 |
Low-memory GPUs (e.g., GTX 1660 Ti) can mine efficiently due to kHeavyHash’s core dominance.
Step-by-Step Mining Guide
1. Set Up a Kaspa Wallet
- Web Wallet: wallet.kaspanet.io.
- Desktop Wallet: kdx.app.
- CLI Wallet: GitHub (link).
Format: Address starts with kaspa: (e.g., kaspa:qpslvun5...).
2. Choose a Mining Pool
| Pool | URL | Fee |
|--------------------|------------------------------------|------|
| WoolyPooly | stratum+tcp://pool.woolypooly.com:3112 | 0.9% |
| Acc-Pool | stratum+tcp://kaspa.acc-pool.pw | 1% |
| Hashpool | stratum+tcp://hashpool.com | 1% |
3. Download Mining Software
Windows Mining Configuration

- Create a flight sheet with lolMiner.
Add dual mining command:
--dualmode KASPADUAL --dualpool pool.woolypooly.com:3112 --dualuser kaspa:YOUR_ADDRESS- Deploy to rigs.
Overclocking & Efficiency
- NVIDIA: High core clock (+150), low memory (-500).
- AMD: Core voltage tweaks (e.g., RX 6800 XT at 1.8V).
Power Tip: Reduce PL (Power Limit) to optimize efficiency.
FAQ
1. Is Kaspa mining profitable in 2024?
Yes, but profitability depends on electricity costs and GPU efficiency. Use Minerstat for estimates.
2. Can I CPU mine Kaspa?
Technically yes, but GPUs are 100x faster.
3. What’s the best pool for beginners?
WoolyPooly (low fees, reliable payouts).
