A permissioned ledger is a blockchain where participants of the network are already known and trusted.
Permissioned ledgers do not need to use a distributed consensus mechanism; instead, an agreement protocol is used to maintain a shared version of the truth about the state of the records on the blockchain.
Balancing Transparency with Access Control in Blockchain
In this case, for verification of transactions on the chain, all verifiers are already preselected by a central authority and typically there is no need for a mining mechanism.
By definition, there is also no requirement for a permissioned blockchain to be private, as it can be a public blockchain but with regulated access control.
For example, Bitcoin can become a permissioned ledger if an access control layer is introduced on top of it that verifies the identity of a user and then allows access to the blockchain.
Why This Matters for Blockchain Technology
Understanding Permissioned ledger is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
