Blockchain vs distributed ledger technology (DLT) are often used interchangeably, but they differ in structure. Blockchain is a type of DLT where data is stored in blocks that are cryptographically linked to form a chain, ensuring immutability and transparency. Distributed ledgers, however, may not always follow a blockchain structure; they are decentralized databases that enable the sharing of data across a network without a central authority. While both promote decentralization and security, blockchain is a specific implementation of DLT.
