When exploring the world of decentralized technologies, understanding the distinction between blockchain vs distributed ledger is crucial. Although often used interchangeably, these terms represent different concepts.

Blockchain is a specific type of distributed ledger where data is organized into blocks and linked in a chain. Each block contains a list of transactions, and once a block is added to the chain, it’s immutable. This immutability and the chain structure ensure data integrity and transparency. Blockchains are best known for their use in cryptocurrencies like Bitcoin and Ethereum.

Distributed Ledger Technology (DLT) is a broader term encompassing various technologies that distribute data across multiple nodes. Unlike blockchain, DLT doesn’t necessarily organize data into blocks. Instead, it uses different methods to achieve decentralization and consensus, such as Directed Acyclic Graphs (DAGs). DLT can be used for various applications beyond cryptocurrencies, including supply chain management and digital identity.

In summary, while all blockchains are distributed ledgers, not all distributed ledgers are blockchains. Understanding blockchain vs. distributed ledger helps in choosing the right technology based on the specific needs of the application, including factors like scalability, security, and data structure.
