The Complete Crypto & Web3 Glossary

A marketing and decentralization distribution method where a blockchain project sends free cryptocurrency tokens directly to eligible user wallet addresses.

Any cryptocurrency other than Bitcoin, ranging from Layer 1 platform assets (Ethereum, Solana) to DeFi utility tokens and governance assets.

A decentralized exchange system that uses mathematical formulas and user-funded token pools to price assets and execute trades automatically without traditional order books.

The world's first decentralized digital cryptocurrency, created by Satoshi Nakamoto in 2009, operating on a Proof-of-Work peer-to-peer blockchain network.

An online public search engine (e.g., Etherscan, Blockchain.com) that allows users to look up real-time and historical transactions, block data, and wallet address balances.

A distributed, cryptographically secured, immutable digital ledger that records transactions across a decentralized network of computer nodes.

The permanent removal of a specific amount of cryptocurrency tokens from circulation by sending them to an unusable 'null' address (e.g., EIP-1559 on Ethereum).

An offline cryptocurrency wallet storage method (e.g., Ledger, Trezor) that keeps private keys completely isolated from internet connectivity to prevent hacking.

Locking up your cryptocurrency in a Proof of Stake blockchain to help validate transactions and secure the network in exchange for regular interest rewards.

A community-led group governed by computer code (smart contracts) where members vote on decisions using digital tokens instead of a central boss or board of directors.

A peer-to-peer crypto trading platform where users swap tokens directly from their personal wallets through smart contracts without an account or middleman.

Financial services like lending, borrowing, and trading built on blockchains that run automatically through software code without banks or brokers.

A global decentralized blockchain network that allows developers to build smart contracts, decentralized apps (dApps), and digital currencies.

Periodic interest payments exchanged directly between long and short traders in crypto perpetual futures to ensure contract prices stay pegged to spot index prices.

The computational transaction fee paid in native crypto (such as ETH or SOL) to network validators for executing transactions or smart contracts on a blockchain.

A programmed event occurring every 210,000 blocks (roughly every 4 years) in Bitcoin that cuts the block reward issued to miners by exactly 50%, reducing new supply inflation.

A radical, backward-incompatible protocol upgrade to a blockchain that splits the network into two distinct, separate chains (e.g., Bitcoin vs Bitcoin Cash).

A specialized physical electronic device (like Ledger or Trezor) built to store private keys in secure hardware chips offline, signing transactions securely.

The total computational processing power dedicated by miners to securing a Proof-of-Work blockchain network and validating new transaction blocks.

A cryptocurrency investment philosophy advocating holding digital assets long-term through severe market drawdowns rather than attempting short-term trading.

A cryptocurrency wallet software application connected directly to the internet (e.g., MetaMask, Phantom, mobile apps) offering fast transactions but higher vulnerability.

Layer 1 refers to base settlement blockchains (Bitcoin, Ethereum, Solana), while Layer 2 refers to secondary scaling solutions (Arbitrum, Optimism, Base) that process off-chain transactions.

A chain reaction in crypto futures trading where falling prices trigger forced sell orders, which pushes prices lower and triggers even more forced sell orders.

A digital pile of cryptocurrency tokens locked in a smart contract that allows users on decentralized exchanges to buy and sell tokens instantly.
