Technology that allows for distributed ledger systems includes blockchain, which is a decentralized and secure method of recording transactions across multiple sites or devices. Unlike traditional databases, distributed ledgers do not rely on a central authority, enhancing data transparency and security. Blockchain technology enables secure, transparent transactions in various applications, including cryptocurrencies, supply chain management, and smart contracts. The decentralized nature of distributed ledger systems fosters trust and accountability among participants while reducing the risk of fraud.
