what is block chain?

Blockchain is a decentralized, distributed ledger technology that underlies cryptocurrencies like Bitcoin. It consists of a chain of blocks, each containing a list of transactions. What sets it apart is its decentralized and secure nature. Once a block is added, it is difficult to alter previous blocks, ensuring the integrity of the entire chain. This decentralized structure means that no single entity has control, enhancing transparency and reducing the risk of fraud. Beyond cryptocurrencies, blockchain finds applications in various industries, from supply chain management to smart contracts, offering a tamper-resistant and efficient way to record and verify transactions.#BTC #link #etf #USTC
