Binaries are published on GitLab, never served from this pool domain. Verify the SHA256 before running.
CPU & GPU
both are supported and auto-detected โ no flags needed. On Sandglass a strong CPU out-hashes a top GPU, so CPUs are the sweet spot here, but every card counts

1. Get your BRC address โ open browsercoin.org, the wallet is created in your tab. Copy the 64-hex address.
2. Run it. The miner auto-detects your hardware โ no flags needed. Replace
YOUR_64_HEX_ADDRESS with your address:
โธ Auto โ uses CPU + GPU (recommended):
โธ CPU only:

-t N (e.g. -t 8).3. Solo โ keep 100% of every block you find (instead of sharing via PPLNS). Just add .solo to the worker name:
Combine with any mode above (e.g. add
./brc-miner -w YOUR_64_HEX_ADDRESS -o 151.240.19.40:3335 --worker rig1.soloCombine with any mode above (e.g. add
--gpu-only). Same binary, same port โ nothing else to change.Share difficulty is tuned automatically per worker to about one share every 20 s. It never changes what you are paid โ it only controls how often your miner talks to the pool.
