What is the Context of DAG Consensus Protocols?

DAG Consensus Protocols are under active investigation as potential solutions for the scalability limitations observed in conventional blockchain networks. Their non-linear data structure presents different security considerations and trade-offs compared to chain-based systems. Ongoing research evaluates their resilience to attacks and their practical deployment in various digital asset applications.

DAG Consensus Protocols

Definition

DAG Consensus Protocols utilize a Directed Acyclic Graph structure instead of a linear chain to record transactions and achieve network agreement. Unlike traditional blockchains, these protocols permit multiple blocks or transactions to be added concurrently. This design aims to enhance transaction throughput and reduce confirmation times. They represent an alternative approach to distributed ledger technology.
