How to mine CapStash (CAP) with GPU

CapStash is a proof-of-work UTXO chain using the CapStash WPXF algorithm. This guide shows how to connect NPMiner to NushyPool and mine CAP on PPS or Solo.




About the CapStash blockchain

CapStash uses a Bitcoin-like UTXO model and a 60 second target block time , giving miners a familiar address and transaction model while using its own WPXF proof-of-work.

CapStash basics

Use a valid CapStash wallet address before mining. Official mainnet CapStash wallet addresses start with cap1....

  • Address prefix: CAP mainnet addresses start with cap1...
  • Pool fee: 1% on PPS and Solo pool mining



Mining CapStash


CapStash uses CapStash WPXF , a Whirlpool-based proof-of-work algorithm supported by NPMiner for Stratum pool mining.


CapStash Wallet

Create or import a CapStash wallet before mining. You can inspect addresses, blocks and transactions on CapStash Mempool
and use the pool dashboard to monitor your address after your first shares arrive.


Mining hardware

CapStash mining on NushyPool works best on GPU hardware. NPMiner supports NVIDIA CUDA and AMD OpenCL for CapStash.


NPMiner is the supported miner for CapStash pool mining on NushyPool.

To start mining

1. Download and unpack the miner

Download the latest NPMiner release from GitHub and unpack the archive. If Windows warns that the miner is "potentially unwanted software", you may need to allow it in Windows Security settings.

2. Test the connection with the pool

Find the nearest server and ping it. A latency under 100 ms is ideal for stable mining.

$ ping nushypool.com
3. Run the miner

Run NPMiner with your CapStash wallet address and a worker name of your choice.

$ ./npminer -a capstash -o stratum+tcp://nushypool.com:40011 -u cap1YOUR_WALLET -w myworker

You can also generate a ready-to-run command on the CAP Pool Page using the "Start Mining" button.

For real-time alerts about your workers and payouts, subscribe to our Telegram bot - it notifies you when a worker goes offline or when a payout is sent.

Good luck!
