Blockchain is a type of shared database that differs from a regular database in how it stores information; Blockchains store data in blocks, which are then linked to each other using cryptography.
Cryptocurrency is a form of digital asset based on a network distributed over a large number of computers. This decentralized structure allows them to exist outside the control of governments and central authorities.
Decentralized applications, also known as “dApps” or “dapps”, are digital applications that run on a network of blockchain computers instead of relying on a single computer.
