Distributed ledger technology (DLT) refers to a decentralized digital system that records transactions across multiple locations simultaneously. In the context of blockchain, this technology ensures that all participants in a network share the same database, enhancing transparency and trust. Each transaction is added in a secure, immutable manner, making it resistant to tampering or unilateral changes. DLT is foundational for cryptocurrencies and enables innovative applications in various sectors, including finance, supply chain, and identity verification, by allowing for more efficient and accountable record-keeping.
