- Mining: The process of validating transactions and adding them to the blockchain in proof-of-work (PoW) networks like Bitcoin. Miners use computational power to solve complex mathematical puzzles.
- Proof of Work (PoW): A consensus mechanism where miners solve complex mathematical puzzles to validate transactions and secure the blockchain. Bitcoin uses PoW.
- Proof of Stake (PoS): A consensus mechanism where validators are chosen to create new blocks and validate transactions based on the amount of cryptocurrency they hold and are willing to "stake" as collateral.
- Smart Contracts: Self-executing contracts with the terms of the agreement directly written into code. They run on blockchain platforms like Ethereum.
- Token: A digital asset built on an existing blockchain, like Ethereum, that can represent anything from a unit of currency to assets or rights within decentralized applications (dApps).
- NFT (Non-Fungible Token): A unique, one-of-a-kind digital asset that represents ownership or proof of authenticity of an item (often digital art or collectibles) on a blockchain.

- Fork: A change or upgrade to a blockchain's protocol. A "hard fork" results in a permanent divergence, often leading to the creation of a new cryptocurrency (e.g., Bitcoin Cash from Bitcoin).
- Gas: A term used on the Ethereum network to refer to the fees required to execute transactions or smart contracts. Gas prices fluctuate based on network demand.
- DApp (Decentralized Application): An application that runs on a blockchain or peer-to-peer network, rather than relying on centralized servers.
- HODL: A term meaning "hold on for dear life," often used to describe the strategy of holding onto cryptocurrencies long-term, rather than selling during price dips.
- FOMO (Fear of Missing Out): A psychological phenomenon where investors buy into a cryptocurrency due to the fear that they will miss out on potential gains if they don't act quickly.
- FUD (Fear, Uncertainty, Doubt): Negative or misleading information spread to create fear and doubt about the market or a particular cryptocurrency, often to manipulate prices.
- Pump and Dump: A market manipulation tactic where a group inflates the price of a cryptocurrency (the pump) and then sells it off rapidly (the dump), leaving other investors with losses.
- Whale: A person or entity that holds a large amount of a particular cryptocurrency and can influence its price through buying or selling actions.
- Tokenomics: The study and design of the economic model behind a cryptocurrency or token, including its distribution, utility, and incentives.
- Rug Pull: A type of cryptocurrency scam where developers of a cryptocurrency or token project suddenly withdraw all funds from the liquidity pool, abandoning the project and leaving investors with worthless tokens. It’s often seen in low-market-cap or unverified projects.
