A decentralized network’s distributed ledger is a database that is updated and synchronized across numerous nodes or computers. Without the requirement for a centralized authority, it enables participants to securely and transparently record, preserve, and amend transactions or data. Blockchain systems are based on distributed ledger technology, which offers an unchangeable and impenetrable record of all network activity.
To increase efficiency and accountability, they are widely employed in many different areas, including finance, supply chains, and healthcare.
