• DApp (Decentralized Application): An application running on a blockchain without centralized control.
• Difficulty: A measure of how hard it is to mine a new block on a blockchain.

E

• Ethereum (ETH): A leading blockchain platform that introduced smart contracts and decentralized applications.
• Exchange: A marketplace where users buy, sell, and trade cryptocurrencies.
• ERC-20: A standard for tokens created on the Ethereum blockchain.

F

• Fiat Currency: Government-issued money that is not backed by a physical commodity, like the US dollar or Euro.
• Fork: A change to a blockchain protocol that creates a split into two different versions.

• Genesis Block: The first block ever mined on a blockchain network.
• Governance Token: A token that gives holders voting rights in a decentralized project or DAO.

H

• Halving: A process where the block rewards for miners are cut in half, reducing the rate of new coin creation.
• HODL: A crypto slang term for holding onto assets despite market fluctuations, originally a typo of “hold.”
• Hash Rate: The computational power used to mine and process transactions on a blockchain.

I

• ICO (Initial Coin Offering): A fundraising method where new cryptocurrencies sell tokens to early investors.
• Immutable: A property of blockchain that ensures once data is recorded, it cannot be changed.
• Interoperability: The ability of different blockchain networks to communicate and share data.

J

• JOMO (Joy of Missing Out): A mindset where investors feel relief about avoiding risky investments.

K

• KYC (Know Your Customer): A regulatory process requiring users to verify their identities before using crypto services.

L

• Layer 1: The base protocol of a blockchain network, such as Bitcoin or Ethereum.
• Layer 2: Solutions built on top of a Layer 1 blockchain to improve scalability and speed.
• Liquidity: The ease with which an asset can be bought or sold without affecting its price.
• Lightning Network: A Layer 2 solution for Bitcoin that enables faster and cheaper transactions.

M

• Market Cap (Market Capitalization): The total value of a cryptocurrency, calculated by multiplying the price per coin by the total supply.
• Mining: The process of validating and adding transactions to a blockchain while earning rewards.
• Mainnet: A fully developed and operational blockchain network.

N

• NFT (Non-Fungible Token): A unique digital asset stored on a blockchain, often used for art, collectibles, and gaming.
• Node: A computer that maintains a copy of the blockchain and participates in network security.
• Nonce: A number used in mining to generate valid hashes in proof-of-work consensus.

O

• Oracle: A service that brings off-chain data onto the blockchain for smart contracts.
• On-Chain Transactions: Transactions that are recorded directly on the blockchain ledger.

P

• Private Key: A secret code that allows users to access and control their crypto funds.
• Public Key: A cryptographic key that is shared publicly and used to receive cryptocurrency.
• Proof of Stake (PoS): A consensus mechanism where validators are chosen to confirm transactions based on the number of tokens they hold.
• Proof of Work (PoW): A consensus mechanism where miners solve complex mathematical problems to validate transactions.

Q

• Quantum Computing: An advanced form of computing that could potentially break current cryptographic security measures used in blockchain technology.

R

• REKT: A slang term meaning “wrecked,” referring to heavy financial losses in crypto trading.
• Rug Pull: A type of scam where developers abandon a project and take investors’ funds.

S

• Smart Contract: A self-executing contract with terms directly written into code, running on blockchain networks.
• Stablecoin: A cryptocurrency designed to have a stable value by being pegged to assets like fiat currency.
• Staking: The process of locking up cryptocurrency to earn rewards and support network security.

T
