Definition ∞ A public permissioned ledger is a blockchain where anyone can view transactions, but only authorized participants can validate them. This type of distributed ledger combines aspects of both public and private blockchains, offering transparency to all observers while restricting the ability to write or validate transactions to a predefined group of entities. Participants typically undergo an identity verification process to gain permission to operate nodes or contribute to consensus. This structure is often chosen for enterprise applications requiring both data integrity and controlled access.
Context ∞ Public permissioned ledgers are gaining traction in sectors like supply chain management and interbank settlements, with news often reporting on consortia and enterprises adopting these systems. The balance between decentralization, control, and efficiency remains a key discussion point. Regulatory bodies are also examining their potential for compliance and data governance in specific industry applications.
