A permissioned ledger is a blockchain where participation requires explicit authorization. Unlike public, permissionless blockchains, access to read, write, or validate transactions on a permissioned ledger is restricted to pre-approved entities. This controlled environment allows for greater privacy, higher transaction throughput, and easier regulatory compliance, as all participants are known and verified. Such ledgers are frequently utilized by consortia or enterprises for specific business applications where confidentiality and governance are paramount.
Context
News often contrasts permissioned ledgers with public blockchains, particularly in discussions about enterprise adoption and central bank digital currencies (CBDCs). Reports frequently highlight their advantages for regulated industries seeking controlled data sharing and enhanced privacy features. A key debate involves whether permissioned systems truly align with the decentralized ethos of blockchain, given their centralized control over participation. Despite this, permissioned ledgers are gaining traction for specific use cases requiring strict access controls and robust governance.
