Blockchain and distributed ledger technology (DLT) are often used interchangeably, but they have distinct differences. Blockchain is a specific type of distributed ledger that organizes data into blocks, which are linked chronologically. This structure ensures transparency and security through consensus mechanisms. In contrast, distributed ledger technology encompasses various architectures that may not use the block structure, allowing for greater flexibility. While both technologies share the core principle of decentralization, blockchain is the most recognized form, especially in cryptocurrency applications.
