Permissioned Ledger

A Permissioned Ledger pertains to a ledger where the actors are required permission to access the ledger in question. Once a new record is added, the integrity of the ledger is checked through a limited consensus process. This is done through trusted actors, for instance, central banks and government institutions. This makes the maintenance of the shared record to be much simpler than that of a consensus performed by ledgers which are unlicensed.

Permissioned blockchains are able to provide highly-verifiable data sets. This is the case as the consensus process allows for the creation of a digital signature that all parties involved can see. Naturally, Permissioned Ledgers are speedier than uncommissioned ones.
