Network Validation

Definition ∞ Network Validation is the process by which transactions and blocks are verified for correctness and adherence to protocol rules within a distributed ledger system. Participants in the network, often referred to as validators or miners, execute cryptographic checks and consensus algorithms to confirm the legitimacy of proposed additions to the blockchain. Successful validation ensures the integrity and immutability of the ledger.
Context ∞ Network Validation is a fundamental aspect of blockchain operation, and its efficiency and security are subjects of continuous discussion. News reports often detail changes to validation mechanisms, such as upgrades to consensus algorithms or the introduction of new validator requirements, which can impact transaction speeds and network security. Debates frequently arise regarding the decentralization of validation power and the potential for centralization risks.
