Blockchain provides a shared, distributed ledger with the added characteristics of immutability, consensus, provenance, and finality, so participants know they can trust this view. In addition, rather than each participant maintaining their record of the state of the network, blockchain lets them all view and update a single ledger instead. This means less paperwork, less time spent trying to reconcile different points of view, less time dealing with disputes, and less need for third parties to adjudicate disputes.
