Blockchain technology represents a fundamental shift in how digital information is recorded, verified, and shared across the global landscape. At its core, a blockchain is a decentralized, distributed ledger that maintains a continuously growing list of records, called blocks, which are secured using advanced cryptography. Unlike traditional centralized databases managed by a single entity—such as a bank or a government agency—blockchain operates on a peer-to-peer network where every participant (or node) maintains a copy of the entire ledger. This structural decentralization ensures that no single party has total control over the data, fostering a “trustless” environment where security is derived from mathematical algorithms rather than human intermediaries.
