Definition ∞ A permissioned system, in the context of distributed ledger technology, is a network where participants must obtain authorization to join and interact with the ledger. Access controls dictate who can view, submit, or validate transactions. This contrasts with permissionless systems, which are open to all. Permissioned systems offer greater control and often higher transaction speeds.
Context ∞ News frequently discusses permissioned systems in enterprise blockchain applications and central bank digital currency (CBDC) initiatives, highlighting their suitability for regulated environments. Debates often center on the trade-offs between control, privacy, and the degree of decentralization compared to public blockchains. A critical future development involves hybrid models that blend aspects of both permissioned and permissionless architectures.
