What is blockchain? At its core, blockchain is a decentralized digital ledger. Unlike traditional databases controlled by a central authority, blockchain records transactions across multiple computers, ensuring transparency and security. Each record, called a block, is linked to the previous one, forming a chain—hence the name.

How Does It Work? Every time a transaction occurs, it’s verified by a network of computers (called nodes) and added to a block. Once confirmed, this block is permanently attached to the chain and cannot be altered. This immutability makes blockchain ideal for secure and tamper-proof record-keeping.
