Blockchain

Blockchain is a decentralized digital ledger technology that records transactions across multiple computers, ensuring security, transparency, and immutability. Each record, known as a block, contains transaction data, a timestamp, and a cryptographic hash of the previous block, forming a chain. This structure makes altering data in one block nearly impossible without changing subsequent blocks, providing strong protection against tampering. Blockchain operates without a central authority, making it particularly useful for industries like finance, supply chain, and healthcare, where trust and verification are critical. It is the underlying technology behind cryptocurrencies like Bitcoin, but its potential applications extend far beyond digital currencies. Blockchain enhances efficiency, reduces fraud, and increases accountability, making it an innovative solution for various sectors seeking secure and transparent data management.
