Blockchain technology is a decentralized and distributed digital ledger that records data in a series of interconnected blocks, ensuring transparency, security, and immutability. Each block contains a cryptographic hash of the previous block, which makes altering past records extremely difficult without affecting the entire chain. This structure eliminates the need for a central authority and allows trust to be maintained across a network of participants. A well-known example of blockchain in practice is Bitcoin (BTC), a digital currency that operates entirely on a blockchain network. All Bitcoin transactions are verified by network nodes and permanently recorded on the blockchain, making the system both transparent and resistant to fraud. As a result, blockchain technology is not only foundational to cryptocurrencies but is also being explored in various industries such as finance, supply chain, and data management.
