A consortium blockchain is a type of blockchain that is governed by a group of organizations rather than being open to the public. This structure allows for greater control and privacy compared to public blockchains.In a consortium setup, multiple trusted entities come together to jointly maintain the network. This arrangement can lead to faster transaction speeds and increased efficiency, as consensus may not require extensive computational resources. Participants in the consortium can establish rules that govern how the blockchain operates, including how data is shared and validated.Consortium blockchains are often used in industries where multiple stakeholders need to collaborate while ensuring data security and integrity. Examples include supply chain management, finance, and healthcare, where organizations might share information but want to keep certain aspects confidential.Overall, consortium blockchains balance the benefits of decentralization with the need for privacy and control among a select group of participants.
