Blockchain

A distributed, decentralized ledger technology that records transactions across multiple computers.

Detailed Explanation

Blockchain is a revolutionary technology that maintains a secure, transparent, and tamper-proof record of transactions. Each block contains a cryptographic hash of the previous block, creating an immutable chain. This decentralized structure eliminates the need for a central authority, making it ideal for applications requiring trust and transparency without intermediaries.
