Every blockchain is governed by a set of rules - a protocol - that must be followed by community members. Using those rules, specific parameters and requirements for mining, staking, node connections, transaction specifics, and extra must be followed by means of all members.

A blockchain protocol is the set of rules and procedures governing the operations of a blockchain network. It defines how transactions are verified, added to the blockchain, and maintained across the decentralized network of nodes. These protocols establish consensus mechanisms to ensure agreement among participants on the validity of transactions, often through processes like proof of work or proof of stake. Additionally, blockchain protocols dictate the structure of blocks, cryptographic algorithms for securing data, and rules for incentivizing network participants. Examples of popular blockchain protocols include Bitcoin's protocol, which underpins its cryptocurrency, and Ethereum's protocol, which supports smart contract functionality. A robust and well-designed protocol is essential for ensuring the integrity, security, and scalability of a blockchain network.
