True.
Consortium blockchain has a predefined set of nodes that are allowed to write data onto the blockchain. These nodes are typically controlled by a group of organizations that have agreed to participate in the consortium and have a stake in the network. Unlike public blockchains such as Bitcoin or Ethereum, where anyone can participate as a node and write data onto the blockchain, consortium blockchains are designed to be more private and controlled. This makes them suitable for enterprise applications where data privacy and confidentiality are paramount. However, consortium blockchains are still decentralized and allow for multiple parties to verify and validate transactions on the network.
