Distributed Ledger Technology (DLT) combines technology and protocols to validate and record transactions on an ledger that is spread across multiple locations and encrypted. The ledger is often decentralized and does not have one authoritative service or trusted third-party. The benefit of this is that the ledger being highly decentralized across distributed networks eliminates the need for a central authority to keep a check against manipulation. Increasing security and resilience.
Once the information is stored on the DLT it becomes an immutable record.
