Blockchain: A decentralized, digital ledger that records transactions across a network of computers.
Decentralization: The distribution of data and control across multiple nodes (computers) in a network, ensuring no single point of failure or control.
Node: A computer or device that participates in a blockchain network by validating and storing transaction data.
Smart Contract: A self-executing contract with terms directly written into code, enabling automatic transactions without intermediaries.
Consensus Mechanism: The process by which participants in a blockchain network agree on the validity of transactions.

- Cold Wallet: Offline storage (e.g., hardware wallets or paper wallets).

Mining: The process of validating blockchain transactions and adding them to the ledger. Miners are rewarded with cryptocurrency.
Halving: A scheduled reduction in the reward for mining new blocks on a blockchain, usually occurring every four years for Bitcoin.
