Solo Mining
Mining Bitcoin independently without joining a mining pool. The miner keeps the entire block reward if successful, but faces extremely low odds of solving a block.
Mining Pool
A group of miners who combine their computational power to increase the chance of solving a block. Rewards are distributed proportionally based on contributed hashrate.
Hashrate
The speed at which a mining device or network performs cryptographic calculations, measured in TH/s, EH/s, ZH/s, etc. Higher hashrate means higher mining probability.
Block Reward
The BTC awarded to the miner or pool that successfully mines a new block, including the block subsidy and transaction fees.
Block Subsidy
The fixed amount of new Bitcoin created with each mined block. It is halved approximately every four years (Bitcoin Halving).
Transaction Fees
Fees paid by users to have their transactions included in a block. These fees are collected by the winning miner.
Bitcoin Halving
A pre-programmed event that cuts the block subsidy in half, reducing Bitcoin’s inflation rate and controlling total supply.
Difficulty Adjustment
A network mechanism that changes mining difficulty every 2016 blocks to maintain an average block time of ~10 minutes.
Block Time
The average time between the creation of consecutive blocks on the Bitcoin blockchain, targeted at 10 minutes.
Nonce
A random number used in cryptographic hashing during the mining process. Miners repeatedly test nonces to find a valid block hash.
- ASIC (Application-Specific Integrated Circuit)Specialized hardware designed exclusively for Bitcoin mining, far more efficient than CPUs or GPUs.
- GPU MiningMining using graphics cards, historically used for Bitcoin but now largely unprofitable due to ASIC dominance.
- NodeA computer that connects to the Bitcoin network to validate transactions and blocks. Miners must run a node to mine.
- Full NodeA node that stores the entire Bitcoin blockchain and independently verifies all rules and transactions.
- Miner FirmwareSoftware embedded on mining hardware that controls performance, efficiency, and connection to pools.
Mining Economics & Metrics
- Hash EfficiencyThe ratio of hashrate to energy consumption, measured in J/TH. Lower values indicate more efficient mining.
- Mining DifficultyA numerical value representing how hard it is to find a valid block hash. Adjusted based on total network hashrate.
- Luck FactorIn mining pools, a ratio comparing actual blocks found to the expected number based on hashrate. Luck >1 means better-than-expected results.
- ROI (Return on Investment)The time required for mining revenue to offset the cost of hardware, electricity, and operational expenses.
- Electricity Cost Per TH/sA key profitability metric, representing the cost of power to generate one terahash of computing power per second.
