Public Blockchains: Fully open networks where anyone can participate, read, and write transactions. Examples: Bitcoin, Ethereum. They offer maximum decentralization but have slower performance. Private Blockchains: Restricted networks controlled by a single organization. Only authorized participants can access and validate transactions. They provide faster performance and privacy but sacrifice decentralization. Consortium Blockchains: Semi-decentralized networks controlled by a group of organizations. Validation rights are restricted to pre-selected nodes. They balance performance, privacy, and partial decentralization. Common in supply chain and banking consortiums.
