Blockchain is a cryptocurrency blockchain explorer service, as well as a cryptocurrency wallet and a cryptocurrency exchange supporting Bitcoin, Bitcoin Cash, and Ethereum. They also provide Bitcoin data charts, stats, and market information.
Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding). Virtually anything of value can be tracked and traded on a blockchain network, reducing risk and cutting costs for all involved.
