Minimum quorum refers to the smallest number of participants or nodes required to validate and agree on transactions or blocks within a network. This concept is crucial for maintaining consensus and ensuring that decisions affecting the blockchain are made collaboratively.In a decentralized system, achieving a minimum quorum helps prevent malicious actors from taking control or manipulating the network. When a sufficient number of nodes reach agreement, it enhances the security and reliability of the data being processed.For example, if a network has 10 nodes and the minimum quorum is set at 7, at least 7 nodes must approve a transaction for it to be considered valid. This mechanism aids in preventing double-spending and other types of fraud.Establishing an appropriate minimum quorum balances efficiency with security. Too low a quorum may lead to vulnerability, while too high a quorum could slow down transaction processing. Ultimately, it plays a vital role in governance and the stability of the system.
