Blockchain technology is a decentralized, distributed digital ledger system that records the history of transactions across a peer-to-peer network. It uses cryptography to secure and verify each transaction, making it virtually impossible to tamper with or corrupt any data stored in the blockchain. By using a network of shared data, blockchain technology creates a permanent and transparent record that cannot be altered or deleted, allowing for secure and efficient communication between participants. Blockchain technology is being used in various industries, from finance and banking to social media, healthcare, and more.
