Is the underlying technology behind the next generation Internet, also referred to the Decentralized Web, or the Web3. The blockchain is a novel solution to the age-old human problem of trust. It provides an architecture for so-called trustless trust. It allows us to trust the outputs of the system without trusting any actor within it.

It is a distributed database that maintains a continuously growing list of transaction data records, cryptographically secured from tampering and revision.
