Quorum refers to the minimum number of participants needed to validate a transaction or reach a consensus in a decentralized network. This concept is crucial for ensuring that decisions are made fairly and that the system functions effectively.In many blockchain systems, a quorum is necessary to ensure that a transaction is legitimate and to prevent issues such as double spending. For example, in proof-of-stake or proof-of-work systems, a certain percentage of validators must agree on the state of the ledger before a block can be added.Quorum can vary widely based on the network’s consensus mechanism. Some may require a simple majority, while others might need a supermajority or a specific percentage of nodes to participate.Establishing a quorum helps maintain security and trust in the network, as it ensures that no single party has control over the decision-making process. This collective agreement fosters transparency and accountability among participants, making it a fundamental aspect of decentralized systems.
