For a lot of people, blockchain means Bitcoin, and Bitcoin is part of blockchain. In reality, however, Bitcoin is a single financial product developed on top of the blockchain technology. Blockchain itself is a series of large segments of records — known as blocks — linked to one another using cryptography. Blocks of information are then stored across a vast network in a decentralized way.
The very nature of blockchain technology is the reason why it can offer many advantages compared to traditional database-reliant recordkeeping. At its core, the way blockchain stores information makes the entire network safe from unauthorized data modifications. Blocks are validated, and the network operates and updates itself through peer-to-peer connections (P2P).
