Panda BRC Pool

panda-miner-brc 1.0.6 · CPU flight sheet

Update the installation URL to 1.0.6 first. Once installed, set Pool URL to https://brcpool.hckj.app/pool, then use the complete Extra config below. It works on both Intel and AMD; existing auto settings can be kept. Version 1.0.5 does not recognize the new domain's developer-fee exemption, so upgrade before changing the URL.

Backup mining URL: https://198.135.48.38:444/pool. Both addresses connect to the same pool; existing rigs on the backup URL can keep using it.

1. Package download: panda-miner-brc-1.0.6.tar.gz. Enter the installation URL below in Hive's custom miner settings.
2. Create a BRC wallet entry with your own 64-character public address, create a CPU flight sheet and select Custom.
3. Use the settings below. Keep existing GPU settings. Update and verify one CPU rig before a fleet rollout.

{"MINER_MODE":"pool","CPU_PERCENT":80,"MINER_NATIVE":1,"MINER_KERNEL":"auto","JOB_WAIT_S":25,"JOB_POLL_MS":1000}

Default: CPU_PERCENT=80; set 60, 90 or 100 to adapt to different CPUs without specifying the same thread count. The limit considers ancestor container CPU quotas, CPU affinity and logical CPU count.MINER_KERNEL=auto selects dual on Intel (physical cores) and dual-smt on AMD (physical cores first, then SMT). It falls back to standard if vendor or topology information is unavailable. Intel dual may use less than the configured ceiling. If cgroup limits cannot be written, threads and software throttling provide an approximate CPU budget. To use the original kernel, set MINER_KERNEL=standard.

To set a fixed thread count manually, use {"MINER_MODE":"pool","CPU_PERCENT":0,"MINER_WORKERS":20,"MINER_THROTTLE":0.8,"MINER_NATIVE":1}.MINER_THROTTLE sets the duty cycle per thread;MINER_NATIVE=1 enables the native CPU kernel;MINER_WORKER_NAME sets an explicit rig name. Percentage mode overrides manual thread count and throttling.

In this mode, rigs fetch jobs, compute and submit shares;no block sync or MINER_HELPERS setting is needed. The server handles validation, synchronization and broadcasting. Effective hashrate may take a few minutes to appear and fluctuates with shares.

Miner developer fee

When connected to this pool at https://brcpool.hckj.app/pool , the miner developer fee is 0%; the pool separately charges 5% of each PPLNS block. On compatible external pools, about 10% of computed work mines for the developer-fee address, in addition to the external pool's own fee. It is not a fixed 10% deduction from each payout. Startup logs show the rate and fee phase. External pools must support this miner's protocol.

Payout rules

The PPLNS window is twice the network's expected work for the winning block, counted backward from the winning share. Only validated, non-stale shares count; the oldest share at the boundary is weighted proportionally. If the pool has not filled the window, existing valid work is used. Allocation is fixed when a block is found; later shares cannot change it.

Each main-chain block's revenue (subsidy + transaction fees) pays a fixed 5% pool fee. The other 95% is allocated by work within the window, accounted for in the smallest unit with deterministic rounding. Rewards mature after 12 confirmations. Payments are checked every 10 minutes, with a 1 BRC minimum. Each batch contains up to 16 payments and waits for chain inclusion before continuing. The fee account keeps a 0.01 BRC transfer-fee reserve. Orphaned blocks earn no payable reward. If a reorganization affects matured earnings, payments pause and the page shows an alert.

Shared mining does not guarantee fixed block times. Until the pool finds a block, a rig can have hashrate and valid shares while its balance remains zero.
