Blockchain technology is a decentralized, distributed ledger system that records transactions across multiple computers securely. Unlike traditional databases, blockchain is immutable, meaning once data is recorded, it cannot be altered without consensus from the network. Each transaction is stored in a “block,” which is linked to the previous block, creating a “chain.” The most significant benefit of blockchain is its transparency and security. It eliminates the need for intermediaries like banks in financial transactions, making it ideal for various industries, from finance to supply chain management. Moreover, it ensures data integrity through cryptographic techniques, enhancing trust in digital transactions.
