Quorum threshold refers to the minimum number of participants needed to validate a transaction or make a decision within a decentralized network. This concept is vital in maintaining security and ensuring that no single entity has excessive control over the system.In a blockchain or distributed ledger, each participant typically holds a copy of the entire ledger. The quorum threshold helps prevent malicious actors from compromising the system by requiring a consensus from a majority or a predetermined number of participants before any action, such as confirming transactions or updating the ledger, can take place.Different networks may set varying thresholds based on their governance models, security requirements, and scalability concerns. For example, a network with a high quorum threshold may be more secure against attacks, while a lower threshold might allow for faster approvals and greater flexibility. Finding the right balance between security, efficiency, and decentralization is essential for the successful operation of blockchain systems.
