View Progression Quorum

Definition ∞ A view progression quorum refers to the minimum number of validators or nodes required to agree on the state of the blockchain for the network to advance to a new “view” or block. This consensus mechanism ensures that all participants have a consistent understanding of the transaction history. It is a fundamental security requirement in many distributed ledger technologies. Meeting this quorum prevents forks and maintains network integrity.
Context ∞ The concept of a view progression quorum is central to understanding the security and finality properties of various blockchain consensus protocols. News reports often discuss the implications of achieving or failing to achieve this quorum in the context of network stability or potential attacks. Maintaining a robust quorum is vital for the reliable operation of decentralized systems.
