Understanding mining requires understanding its language. This glossary defines the core terms used across Proof of Work networks, explained clearly and concisely.
A
ASIC
An ASIC (Application-Specific Integrated Circuit) is a specialized microchip designed to perform one specific task, and in cryptocurrency mining it is used to calculate a blockchain’s hashing algorithm as fast and efficiently as possible.
ASIC-Resistant
ASIC-Resistant describes a mining algorithm designed to reduce the advantage of ASIC miners, so that hardware like CPUs or GPUs can still compete and mining stays more decentralized.
Address
An address is a unique identifier for a wallet in a cryptocurrency network, used to send and receive transactions.
Algorithm
An algorithm is a set of rules or instructions that a computer follows to solve a problem or complete a task.
B
Block
A block is a data structure that contains a collection of transactions and is added to the blockchain.
Blockchain
A blockchain is a decentralized, distributed ledger that records all transactions across a network of computers.
Block Reward
A block reward is the amount of cryptocurrency awarded to a miner for successfully adding a new block to the blockchain.
Block Size
The block size refers to the maximum amount of data that can be included in a single block on the blockchain.
Block Height
The block height is the number of blocks that have been added to the blockchain since the genesis block.
Block Time
The block time is the time it takes to mine a new block on the blockchain.
Block Header
The block header contains metadata about the block, including the previous block's hash, a timestamp, and the nonce.
Block Hash
The block hash is a unique identifier for a block on the blockchain, generated by applying a cryptographic hash function to the block's header.
C
CPU
A CPU (Central Processing Unit) is the primary component of a computer that performs most of the processing inside a computer.
Coinbase Transaction
A coinbase transaction is a special type of transaction that is created by a miner when they successfully mine a new block.
Consensus
Consensus is the process by which a decentralized network agrees on the state of the ledger.
Confirmation
A confirmation is the number of blocks that have been added to the blockchain since a particular transaction was included.
Circulating Supply
The circulating supply of a cryptocurrency is the total amount of coins that are currently in circulation and available for usage.
E
Explorer
An explorer is a web-based tool that allows users to search and view information about transactions, blocks, and addresses on the blockchain.
Epoch
An epoch is a period of time during which a set of rules or conditions applies to the blockchain.
Effort
Effort is the amount of computational work put into mining a block.
H
Hash
The output of a cryptographic hash function, which is used to uniquely identify data in the blockchain.
Hashrate
The rate at which a mining device can perform hashing operations, typically measured in hashes per second.
Halving
A scheduled event in some cryptocurrencies where the reward for mining a new block is reduced by half.
