Blockchain is the underlying technology that supports cryptocurrencies.
Blockchain is the underlying technology that supports cryptocurrencies. It is an open-source, public record-keeping system operating on a decentralized computer network that records transactions between parties in a verifiable and permanent way. Blockchain provides accountability, as the records are intended to be immutable, which presents potential applications for many businesses. While blockchain has often been associated with cryptocurrency, it has many potential uses beyond payments, including smart contracts, supply chain management, and financial services. Note that ownership of cryptocurrencies is not an investment in blockchain, the technology, or its current or future uses.
