What is Blockchain?



Blockchain is a digital ledger technology that securely records transactions across many computers. Instead of relying on a single central authority, blockchain is decentralized—meaning everyone in the network has access to the same information. Each “block” holds a list of transactions, and these blocks are linked together in a “chain.” Once added, data in a block can’t be changed, making blockchain a secure and transparent way to track things like money, contracts, or even digital assets.

In short, it’s like a shared record book that everyone can trust—without needing a middleman.
