21. Fork: A split or divergence in the blockchain network, resulting in two separate chains with different rules and protocols. Forks can be hard forks (irreversible split) or soft forks (backward-compatible split).
22. Mining: The process of validating and adding new transactions to the blockchain by solving complex mathematical problems, often associated with the PoW consensus mechanism.
23. Hash Function: A mathematical algorithm that takes input data and produces a fixed-size string of characters, commonly used for data integrity and security in blockchain networks.
24. Block Explorer: An online tool or platform that allows users to explore and track transactions, addresses, and blocks on a blockchain network.
25. Peer-to-Peer (P2P): A decentralised network architecture where participants can directly interact and transact with each other without intermediaries.
26. Immutable: In the context of blockchain, it refers to the inability to modify or alter data or transactions once they have been recorded on the blockchain, ensuring data integrity and transparency.
27. Forking: The process of creating a new blockchain protocol or software version from an existing one, often resulting in a separate and independent network with different features or rules.
28. DApp (Decentralised Application): An application built on a blockchain platform that operates without a central authority, leveraging smart contracts and blockchain technology for functionality and security.
29. Gas: In Ethereum, gas refers to the unit of measurement for computational work required to perform transactions or execute smart contracts on the network.
30. Private Blockchain: A blockchain network restricted to a specific group or organisation, often used for internal processes, consortiums, or private applications.
31. Public Blockchain: A blockchain network that is open and accessible to anyone, allowing anyone to participate, validate transactions, and contribute to the network's security.
32. Permissionless: Describes a blockchain or cryptocurrency network that allows anyone to participate, transact, and validate transactions without requiring permission from a central authority.
33. Permissioned: Refers to a blockchain network where participation, transaction validation, or access to certain functionalities is restricted and requires permission from a central authority.
