Blockchain technology is a revolutionary concept that has gained significant attention in recent years. It is a decentralized and distributed ledger system that enables secure and transparent transactions and data management without the need for intermediaries. Originally introduced as the underlying technology for Bitcoin, blockchain has evolved to have far-reaching applications beyond cryptocurrencies.At its core, a blockchain is a continuously growing chain of blocks, where each block contains a list of transactions or other forms of data. These blocks are linked together using cryptographic hashes, creating a tamper-proof and transparent record of all the transactions or data stored on the blockchain.
