Permissioned Ledger

A Permissioned Ledger is a closed-source DLT or Distributed Ledger Technology variant where all the participants are known and the authorization is required prior to the usage or activity validation on the network. These are more suitable for the organizations or the consortiums that possess the requirement of privileged private information far from the public domain. The examples of the permissioned ledgers are R3, B3i and Hyperledger.
