1. Get a KLS address

You need a KLS receiving address whose keys you control: the official Karlsen wallet is the safest choice. Avoid exchange deposit addresses for solo mining: some exchanges do not accept block rewards (coinbase).

2. Download a mining software

Miners that work with Karlsen on VEIN (exact download links and commands are on the pool page):

lolMiner — NVIDIA · AMD · recommended · dev fee 1%
Rigel — NVIDIA · dev fee 1 to 2%

3. Start mining

Replace YOUR_ADDRESS with your KLS address and rig1 with your machine's name. Example with lolMiner:

lolMiner.exe --algo KARLSENV2 --pool veinpool.fr:3470 --user YOUR_ADDRESS.rig1

On Windows, paste this line into a .bat file inside the miner's folder; on Linux or HiveOS use the same parameters.

Pool (PPLNS) or SOLO?

PPLNS pool: everyone's hashrate is combined and each block is split according to the work each miner really did. Steady income, recommended for most rigs.

SOLO: your rig mines alone and keeps the whole block (19.51 KLS) when it finds one. On a small network like Karlsen, a single machine can find blocks regularly; the calculator shows your exact odds.

How much can you earn mining Karlsen?

Earnings depend on your hashrate, the network difficulty and the KLS price. The Karlsen calculator estimates them live (pool and solo); electricity cost is optional. The hardware ranking compares GPUs and CPUs.

Common problems

Antivirus deletes the miner: Windows Defender flags every mining software; add an exclusion for its folder.
No stats on VEIN: check the address, port and hostname; stats appear after the first shares (1 to 2 minutes).
Hashrate lower than expected: update your GPU driver, close heavy apps, and for CPUs enable huge pages (run as administrator).
