Blockchain is a decentralized digital ledger technology that securely records transactions across multiple computers. Each transaction is grouped into a "block," and these blocks are linked together in chronological order, forming a "chain." The system is secure because once a block is added, it cannot be altered without changing all subsequent blocks, making fraud extremely difficult.

copyright, such as Bitcoin and Ethereum, operates on blockchain technology. Unlike traditional currencies controlled by governments and banks, cryptocurrencies are decentralized, meaning transactions occur directly between users without intermediaries. This reduces transaction fees and increases transparency.

Beyond finance, blockchain is being used in various industries, including supply chain management, healthcare, and digital identity verification. As the technology matures, it has the potential to revolutionize data security and online transactions. However, challenges like energy consumption, regulation, and scalability still need to be addressed for widespread adoption. Shutdown123
