What is Blockchain?

Before diving into its impact, it’s essential to understand what blockchain is. At its core, blockchain is a decentralized digital ledger that records transactions across multiple computers in a way that ensures the data cannot be altered retroactively. Each block in the chain contains a list of transactions, and once a block is added, it is linked to the previous one, forming a chain.

Key features of blockchain include:

Decentralization: Unlike traditional systems controlled by a central authority, blockchain operates on a peer-to-peer network, reducing the risk of single points of failure.
Transparency: All transactions on the blockchain are visible to all participants, ensuring accountability and trust.
Immutability: Once a transaction is recorded on the blockchain, it cannot be altered or deleted, making the data highly secure and tamper-proof.

These features make blockchain a powerful tool for industries looking to enhance efficiency, security, and transparency.
