A blockchain is a digital, public transaction record or digital ledger. People usually associate it with the cryptocurrency Bitcoin, but blockchain technology can also record digital transactions with other cryptocurrencies, data, or information. Unlike other forms of finance, cryptocurrencies that rely on the blockchain are decentralized, so people can access Bitcoin and other digital currencies without going to a bank. Computer experts and cryptographers are developing additional ways to use blockchain technology, such as for trade and healthcare records.
