A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves). Since each block contains information about the previous block, they effectively form a chain (viz. linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are resistant to alteration because, once recorded, the
A blockchain is a digital record-keeping system where information is stored in linked blocks secured by cryptography, making it extremely difficult to alter past records without detection. It matters because this structure creates a permanent, tamper-resistant way to track transactions across a distributed network without needing a central authority to verify them.
