DAG Protocols

Definition ∞ DAG protocols are a class of distributed ledger technologies that utilize a Directed Acyclic Graph structure instead of a linear blockchain. Transactions in DAGs are typically linked to multiple previous transactions, allowing for parallel processing and potentially higher scalability. This architectural approach offers an alternative to traditional blockchain designs. They can enable faster transaction confirmation.
Context ∞ News often discusses DAG protocols as potential solutions to the scalability limitations observed in conventional blockchains, especially for high-throughput applications. Debates center on their security properties and the level of decentralization they can achieve compared to established blockchain models. A critical future development involves the maturation of DAG-based networks for mainstream adoption.
