  • Block: A collection of cryptocurrency transactions permanently recorded on a blockchain.
  • Blockchain: A continuous, sequential chain of blocks containing transaction data, secured by cryptographic hashes.
  • Burn: Intentionally removing tokens from circulation, usually to control inflation or improve scarcity.
  • Bull Market: A market condition where prices are rising and optimism is growing.

  • Cross-Chain: Refers to the ability to interact and transact between different blockchain platforms, enhancing interoperability.
  • Cryptography: The science of encrypting and decrypting information to secure transaction data and control the creation of new coins.
  • Custodial: Services or wallets where the service provider manages the security keys, unlike non-custodial alternatives where the user has full control over their keys.
  • DAO (Decentralized Autonomous Organization): An organization that is run through rules encoded as smart contracts, eliminating the need for traditional management.
  • dApp (Decentralized Application): Applications that operate autonomously on a blockchain network without centralized control.
  • DDoS (Distributed Denial of Service): A cyber-attack where multiple systems flood the bandwidth or resources of a targeted system, typically one or more web servers.
  • Decentralization: The process of distributing control away from a central authority and towards a distributed network.
  • DeFi (Decentralized Finance): Financial services built on blockchain technologies that operate without traditional financial intermediaries.
  • DEX (Decentralized Exchange): A blockchain-based exchange that allows users to trade cryptocurrencies directly without the need for an intermediary.
  • Digital Signature: A mathematical scheme for verifying the authenticity of digital messages or documents, crucial in the process of transaction validation.
  • Double Spend: The risk that digital currency can be spent twice, which blockchain technology aims to prevent.
  • Emission Rate: The rate at which new coins are generated and released into the system, often controlled to manage inflation.
  • ERC-20: A standard for creating and issuing smart contracts on the Ethereum blockchain.
  • Escrow: A financial arrangement where a third party holds and regulates payment of the funds required for two parties involved in a given transaction.
  • Exchange: A digital marketplace where cryptocurrencies are bought, sold, and traded.
  • Faucet: A system that distributes a small amount of cryptocurrency for free, often used to generate interest or allow testing.
  • Fiat: Traditional, government-issued currencies such as the US Dollar, Euro, or Japanese Yen.
  • FOMO (Fear of Missing Out): Anxiety that an exciting or interesting event may currently be happening elsewhere, often aroused by posts seen on social media.
  • Fork: The creation of an alternate version of a blockchain, diverging from the original due to changes in protocol.
  • Fork (Hard): A type of fork that creates a permanent divergence from the previous version of the blockchain, requiring all nodes to upgrade to the new protocol.
  • Fork (Soft): A type of fork that is intended to be adopted by all nodes but does not create a permanent divergence in the blockchain network.
  • FUD (Fear, Uncertainty, and Doubt): A disinformation strategy used in sales, marketing, public relations, politics, cults, and propaganda.
  • Gas: A fee paid to conduct transactions and execute smart contracts on Ethereum’s network.
  • Gas Limit: The maximum amount of gas the user is willing to spend on a transaction in the Ethereum network.
  • Gas Price: The amount of ether the user is willing to spend on each unit of gas.
  • Genesis Block: The first block in a blockchain, used to initialize the cryptocurrency.
  • Genesis Mining: The process of the first mining operation ever conducted on the network, which typically generates the first batch of coins.
  • Governance Token: A type of token that gives holders the right to influence decisions concerning the blockchain's operation, including proposed changes to the system.
  • Halving: An event that reduces the block reward given to miners, halving the rate at which new tokens are generated.
  • Hard Cap: The maximum amount of capital that a project can receive from investors during an ICO.
  • Hardware Wallet: A physical device that stores users' private keys securely, not connected to the internet.
  • Hash: A unique, fixed-size cryptographic output used for securing and validating information on the blockchain.
  • Hash Function: A function that converts an input (or 'message') into a fixed-size string of bytes, typically a hash, which is a sequence that represents the original string.
  • Hashrate: The speed at which a computer is completing an operation in the Bitcoin code, a vital performance metric.
  • HODL: Originally a typo for "hold," used in the crypto community to denote holding the cryptocurrency rather than selling it.
  • Hot Wallet: A cryptocurrency wallet that is connected to the internet, which facilitates quick transactions but is less secure.
  • ICO (Initial Coin Offering): A crowdfunding method where new projects sell their underlying tokens in exchange for start-up funds.
  • Immutable: A characteristic of blockchain technology where once data has been written, it cannot be changed.
  • Interoperability: The ability of different blockchain systems to work together without any restrictions.
