Blockchain technology is a decentralized and distributed ledger that allows for the secure, anonymous and immutable tracking of digital assets across a network. This technology has revolutionized the way data is stored and secured by using cryptographic algorithms to link blocks of data together in an encrypted and chronological chain. With blockchain technology, no single authority or controller holds all the data, making it virtually impossible to manipulate or hack. As a result, blockchain technology is being used in a variety of industries, including financial services, healthcare, energy, real estate, and even education.
