Crypto Mining Glossary

Application-Specific Integrated Circuit. A chip designed specifically for Bitcoin mining. ASICs are far more efficient than CPUs or GPUs for mining Bitcoin.

A mining device built around ASIC chips. Examples include the Bitmain Antminer S21 and MicroBT Whatsminer M60. These are the standard hardware for Bitcoin mining today.

The first and largest cryptocurrency by market cap. Created by Satoshi Nakamoto in 2009. Bitcoin uses a Proof of Work consensus mechanism secured by miners.

A bundle of verified Bitcoin transactions. Each block contains approximately 2,000–3,000 transactions and is added to the blockchain roughly every 10 minutes.

The amount of Bitcoin awarded to the miner who successfully mines a new block. After the April 2024 halving, the block reward is 3.125 BTC.

A public, distributed ledger that records all Bitcoin transactions. Each block is cryptographically linked to the previous one, making the chain tamper-proof.

A service where you rent computing power from a company that owns mining hardware. You pay a fee and receive a share of the mining rewards without managing any equipment.

The first transaction in every Bitcoin block, which creates new Bitcoin and awards it to the miner. Not to be confused with the Coinbase exchange.

Each new block added after a transaction is included in the blockchain counts as one confirmation. More confirmations = more security. Most exchanges require 3–6 confirmations.

A digital currency that uses cryptography for security and operates on a decentralized network (blockchain). Bitcoin, Ethereum, and USDT are examples.

Return on Investment per day, expressed as a percentage. A 3% daily ROI on a $500 investment = $15/day. HashRig plans offer 2.5%–4% daily ROI.

A measure of how hard it is to mine a new Bitcoin block. The network automatically adjusts difficulty every 2,016 blocks (~2 weeks) to maintain a 10-minute block time.

Bitcoin's automatic mechanism to keep block times at ~10 minutes. If miners join the network, difficulty increases. If miners leave, it decreases.

An event that cuts the Bitcoin block reward in half, occurring every 210,000 blocks (~4 years). The most recent halving was in April 2024, reducing the reward from 6.25 to 3.125 BTC.

The output of a cryptographic hash function. In Bitcoin mining, miners repeatedly hash block data until they find a hash below the target value.

A mathematical function that converts any input into a fixed-length output. Bitcoin uses SHA-256. The same input always produces the same output, but you can't reverse-engineer the input from the output.

The speed at which a mining device can perform hash calculations. Measured in TH/s (terahashes per second). Higher hashrate = more chances to mine a block.

The process of verifying Bitcoin transactions and adding them to the blockchain. Miners compete to solve a mathematical puzzle, and the winner earns the block reward.

A large facility housing thousands of ASIC miners. Mining farms are typically located in areas with cheap electricity (Iceland, Kazakhstan, Texas).

A group of miners who combine their computing power and share rewards proportionally. Pools reduce variance — instead of rarely winning big, you win small amounts regularly.

A service where individuals rent hashrate from a mining company. Also called cloud mining. HashRig is a mining rental platform.

A computer that participates in the Bitcoin network by storing a copy of the blockchain and validating transactions. There are over 15,000 active Bitcoin nodes worldwide.

A number that miners change repeatedly when trying to find a valid block hash. "Nonce" stands for "number used once."

Earnings that require minimal ongoing effort. Bitcoin mining rental generates passive income — you invest once and receive daily payouts automatically.

Bitcoin's consensus mechanism. Miners must perform computational work (hashing) to add blocks. This work is the "proof" that they expended real resources.

When a mining plan returns your original investment at the end of the contract period. HashRig's Elite and Whale plans include principal return.

The profit from an investment expressed as a percentage of the original investment. A $500 investment that earns $600 total has a 120% ROI.

The smallest unit of Bitcoin. 1 Bitcoin = 100,000,000 satoshis (sats). Named after Bitcoin's creator, Satoshi Nakamoto.

The cryptographic hash function used by Bitcoin. SHA stands for Secure Hash Algorithm. It produces a 256-bit output.

A unit of mining speed. 1 TH/s = 1 trillion hash calculations per second. Modern ASIC miners operate at 100–300 TH/s.

A fee paid by Bitcoin users to have their transactions included in a block. Miners collect these fees in addition to the block reward.

Software or hardware that stores your cryptocurrency private keys and allows you to send and receive crypto. Examples: MetaMask (software), Ledger (hardware).

Transferring cryptocurrency from a platform (like HashRig) to your personal wallet address. HashRig processes withdrawals within 24 hours.
