From blockchain basics to DeFi and NFTs, this guide covers the most important cryptocurrency terms you should know. Let’s dive into the crypto glossary and decode the crypto lingo that defines this innovative industry.
Blockchain Basics
Blockchain
A decentralized digital ledger that records transactions across many computers. Each block contains a list of transactions and is linked to the previous block, forming a chain.
Decentralization
The distribution of authority, control, and decision-making away from a central entity. In blockchain, this means no single entity controls the entire network.
Public Ledger
A transparent record of all transactions on a blockchain, accessible to anyone. This feature enhances trust and accountability.
Distributed Ledger Technology (DLT)
A technology that enables the sharing and synchronization of data across multiple locations, ensuring that all participants have access to the same information.
Node
A computer connected to the blockchain network that validates and relays transactions. Nodes maintain the integrity of the blockchain.
Consensus Mechanism
The method by which nodes agree on the validity of transactions. Common mechanisms include Proof of Work (PoW) and Proof of Stake (PoS).
Cryptography
The practice of securing information through mathematical techniques, ensuring data confidentiality and integrity.
Cryptographic Hash
A function that converts input data into a fixed-size string of characters, which appears random. It is used for securing data in blocks.
Hash Function
An algorithm that transforms input data into a hash value. It ensures that even a small change in input results in a drastically different hash.
Merkle Tree
A data structure used in blockchain to efficiently verify and organize large amounts of data. Each leaf node is a hash of transaction data, while non-leaf nodes are hashes of their child nodes.
Block Height
The number of blocks in the blockchain preceding a specific block. It indicates how far back the block is in the chain.
Double Spending
A risk unique to digital currencies where the same coin is spent more than once. Blockchain technology mitigates this risk through consensus mechanisms.
51% Attack
A situation where an individual or group controls over 50% of the network’s mining power, potentially allowing them to manipulate transactions or double-spend coins.
Cryptocurrencies
Bitcoin (BTC)

Hot Wallet
An online wallet connected to the internet, offering convenience but lower security compared to cold wallets (e.g., exchange wallets).
Custodial Wallet
A wallet where a third party holds your private keys on your behalf. This offers convenience but requires trust in the custodian.
Non-Custodial Wallet
A wallet where you control your private keys, providing greater security and autonomy over your funds.
Transactions & Fees
Gas Fee
A fee paid to miners for processing transactions on networks like Ethereum. It compensates them for computational work.
Mempool
The collection of unconfirmed transactions waiting to be processed by miners. Each node maintains its own mempool.
Slippage
The difference between the expected price of a trade and the actual price due to market fluctuations or low liquidity during execution.
Over-the-Counter (OTC) Trading
Trading directly between parties rather than through an exchange, often used for large transactions to avoid market impact.
Atomic Swap
A technology enabling peer-to-peer exchanges between different cryptocurrencies without intermediaries or centralized exchanges.
Mining & Validation
Mining
The process by which transactions are verified and added to the blockchain through solving complex mathematical problems (used primarily in PoW systems).
Proof of Work (PoW)
A consensus mechanism requiring miners to solve cryptographic puzzles to validate transactions and create new blocks (e.g., Bitcoin).
Proof of Stake (PoS)
A consensus mechanism where validators are chosen based on the number of coins they hold and are willing to “stake” as collateral.
Staking
The process of participating in PoS networks by locking up coins in a wallet to support network operations like transaction validation while earning rewards.
Block Reward
The incentive given to miners or validators for successfully adding a new block to the blockchain, usually consisting of newly minted coins plus transaction fees.
Halving
An event in certain cryptocurrencies where block rewards are cut in half, reducing the rate at which new coins are created (notably occurring in Bitcoin).
