Public Permissioned Blockchain

Definition ∞ A public permissioned blockchain is a hybrid distributed ledger system where anyone can view the transaction history, but participation in validating transactions or adding new blocks requires explicit authorization. This model combines the transparency of public blockchains with the controlled access and governance of private, permissioned networks. Participants typically need to be identified and approved by a central authority or consortium to operate as nodes. It offers a balance between decentralization and regulatory compliance.
Context ∞ Discussions surrounding public permissioned blockchains often appear in news related to enterprise blockchain solutions and central bank digital currencies. Proponents highlight their suitability for regulated industries seeking transparency without sacrificing control over network participants. Critics, however, question whether such systems truly uphold the core tenets of decentralization inherent to public, permissionless blockchains, leading to ongoing debates about their long-term utility and adoption.
