What are Distributed Ledger Technologies (DLT)?

Blockchain is a decentralized, distributed ledger that records transactions across many computers. Unlike traditional databases, it is append-only and immutable.

A blockchain is a chain of blocks where each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Databases are typically centralized and controlled by a single authority (CRUD operations), whereas Blockchains are decentralized (Append-only). This architecture ensures that data cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.
