Blockchain

Blockchain is a decentralized digital ledger technology that records transactions across multiple computers in a way that the registered data cannot be altered retroactively. Each block in the blockchain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. This ensures transparency and security, as all transactions are visible and verifiable by all users, while ensuring that no single entity has control over the entire chain. The distributed nature of blockchain makes it resilient to faults and attacks, fostering trust in the data recorded. Blockchain technology is the backbone of cryptocurrencies like Bitcoin, but its applications extend to various fields including finance, supply chain management, healthcare, and more.
