Introduction
If you’re diving into the world of mining, understanding crypto mining terms is the first step to navigating hardware setups, profitability calculators, and blockchain protocols. Whether you’re learning how a crypto mining motherboard works or comparing altcoins mined on your crypto mining laptop, this glossary will help you speak the language of miners with confidence.Glossary of crypto mining terms (A–Z)
A
- ASIC (Application-Specific Integrated Circuit): A specialized chip designed exclusively for mining a specific algorithm, such as SHA-256 for Bitcoin.
B
- Block: A collection of transactions added to the blockchain once verified by a miner.
- Block Header: Metadata that summarizes a block, including timestamp, previous block hash, and nonce.
- Block Reward: The incentive (in cryptocurrency) miners receive for successfully adding a block to the blockchain.
C
- Cloud Mining: A mining process where users rent hash power from a provider rather than owning physical hardware.
- Consensus Mechanism: The protocol used by blockchain networks to agree on transaction validity. Most common in mining: Proof of Work (PoW).
- CPU Mining: Using a computer’s central processing unit for mining, now mostly obsolete due to inefficiency.
D
- Difficulty: A measure of how hard it is to find a new valid block. Adjusts automatically to maintain block time consistency.
- Dual Mining: The process of mining two cryptocurrencies simultaneously using the same hardware.
E
- Electricity Cost: A major factor in mining profitability. Lower electricity rates typically mean higher mining returns.
- Epoch: In mining, refers to a set number of blocks or a period in which mining conditions (like rewards or difficulty) might change.
F
- FPGA (Field Programmable Gate Array): A configurable chip used for mining before ASICs became dominant.
- Fork: A split in a blockchain that can create a new path, possibly forming a new coin.
G
- GPU (Graphics Processing Unit): Hardware used in most modern mining rigs, especially efficient for altcoins like Ethereum or Ravencoin.
- Gwei: A subunit of Ether used to price gas fees for Ethereum mining.
H
- Hash: An output of a cryptographic function that miners try to solve for each new block.
- Hash Rate: The number of hashes a miner or network can compute per second. Higher hash rate = more mining power.
- Halving: A pre-programmed event in some blockchains (e.g., Bitcoin) that reduces the block reward by 50%.
I
- Idle Time: The period when mining hardware is powered on but not actively hashing due to network or configuration issues.
K
- kWh (Kilowatt-Hour): A standard unit of energy measurement crucial in mining, representing the amount of energy consumed. Lower kWh costs directly improve mining profitability.
- kHeavyHash: A lightweight, energy-efficient hashing algorithm used in some next-generation cryptocurrencies optimized for GPU mining.
- Keccak: A cryptographic hash function used in blockchain technology and some mining algorithms, offering high security and speed.
L
- Latency: Delay between sending a mining request and receiving a response, important in mining pool performance.
- Liquidity: While not specific to mining, liquidity affects whether mined coins can be easily converted to fiat or other assets.
M
- Mempool: A pool of unconfirmed transactions waiting to be included in a block.
- Mining Pool: A group of miners who combine their hash power to increase chances of earning rewards.
- Mining Rig: A computer specifically assembled for cryptocurrency mining, usually with multiple GPUs or ASICs.
- Mining Difficulty Adjustment: An automatic recalibration of mining difficulty based on how fast or slow blocks are being found.
- Mining Profitability Calculator: Online tool that estimates expected earnings based on hardware specs and electricity costs.
N
- Nonce: A variable number miners adjust to produce a hash below the target difficulty threshold.
- Node: Any computer that participates in the blockchain network by maintaining a copy of the ledger.
O
- Overclocking: Adjusting a GPU or ASIC to run at higher speeds than the default to improve mining performance.
P
- Proof of Work (PoW): A consensus algorithm where miners solve mathematical problems to validate transactions.
- Proof of Stake (PoS): A consensus mechanism where validators are chosen based on the number of coins they hold and are willing to lock up as collateral.
- Power Supply Unit (PSU): Hardware component that delivers electricity to the mining rig.
R
- ROI (Return on Investment): A measure of how long it will take to recoup the cost of mining equipment.
- Risers: Extensions that allow GPUs to be spaced apart in a mining rig.
S
- SHA-256: A cryptographic hash function used in Bitcoin and other PoW cryptocurrencies.
- Stale Share: A valid share submitted too late; not accepted by the pool.
T
- Temperature Control: A critical part of mining that affects hardware longevity and performance.
- Terahash (TH/s): A measure of hash rate; one trillion hashes per second.
U
- Uptime: The amount of time a mining system is online and operational.
V
- Voltage Tuning: Adjusting power input to GPUs or ASICs to optimize energy consumption.
W
- Wallet: Software or hardware used to store mined cryptocurrency securely.
- Watts: A measurement of power usage. Lower wattage per hash = more efficient mining.
Z
- Zero Confirmation: A transaction that has been broadcast but not yet confirmed in a block. Less relevant to mining, but still important.
