What Is Blockchain?
Blockchain is a decentralized digital ledger that securely records transactions across a network of computers. Each transaction is stored in a "block" and linked to previous ones, forming a tamper-proof "chain." This ensures that once data is recorded, it cannot be altered, providing immutability and security.
Blockchain is transparent, allowing all participants in the network to view the transactions. While commonly associated with cryptocurrencies like Bitcoin, blockchain has applications in various industries such as finance, supply chain, and healthcare.
