- Hashrate (TH/s, GH/s, MH/s)
- How many hash calculations the rig performs per second — tera-, giga-, and mega-hashes per second respectively. Higher generally means more mining reward, at the cost of more power.
- Efficiency (J/TH, J/MH)
- Joules of energy spent per unit of hashrate — effectively power draw divided by hashrate. The number that determines your electricity cost per coin mined.
- Stratum
- The protocol miners use to communicate with a pool — submitting work and receiving new jobs. Pool addresses are given as a stratum URL and port.
- Worker
- A label identifying one specific miner under your pool account, so you can track multiple rigs separately in the pool's dashboard.
- Share
- A unit of proof-of-work submitted to the pool. Pools track accepted vs. rejected shares to calculate your portion of the block reward.
- Difficulty
- A network-wide measure of how hard it currently is to find a valid block. It adjusts over time as total network hashrate changes.
- Pool fee
- The percentage a mining pool takes from your earned reward in exchange for smoothing out payout variance versus solo mining.
- Control board
- The miner's onboard computer — runs the firmware, hosts the web dashboard, and coordinates the hashboards.
- Hashboard / chain
- The physical board holding the ASIC chips that do the actual hashing. Most rigs have 3 hashboards, each called a "chain" in the dashboard.
- PDU
- Power Distribution Unit — a rack-mount power strip built for sustained high-current loads, standard in multi-rig setups.
