What is Blockchain?
Blockchain is a decentralized, digital ledger that records transactions across multiple computers. Each "block" contains a set of transactions, and these blocks are linked in chronological order, forming a "chain." The technology ensures data integrity through cryptographic hashing, making it secure and tamper-proof.
Unlike traditional centralized systems, blockchain operates on a peer-to-peer network, promoting transparency and eliminating the need for intermediaries. Its applications span various sectors, including finance (cryptocurrencies), supply chain management, healthcare, and voting systems. Blockchain is revolutionizing how data is stored, shared, and verified, paving the way for a more secure and efficient digital future.
