A distributed ledger is an asset database that can be shared across a network of multiple sites, geographies or institutions.
All participants in the network can have their own identical copy of the distributed ledger.
Any changes to the distributed ledger are reflected in all copies in minutes, or in some cases, seconds.
The assets can be financial, legal, physical or electronic. The security and accuracy of the assets stored in the ledger are maintained through the use of encrypted ‘keys’ and signatures to control who can do what within the shared ledger.
Entries can also be updated by one, some or all of the participants, according to rules agreed by the network.
