Definition ∞ Dual-layer consensus involves two distinct agreement mechanisms working together in a blockchain system. This architectural approach utilizes separate consensus protocols for different operational layers within a single blockchain network. Typically, one layer handles broad network security and finality, while another manages faster, more frequent transaction processing. This design aims to balance the security of a foundational layer with the scalability and efficiency required for high transaction volumes.
Context ∞ The implementation of dual-layer consensus models is a key strategy for addressing the scalability limitations of many foundational blockchain networks. Discussions often revolve around the security implications of delegating certain functions to a secondary layer and ensuring seamless coordination between the two. Future developments will focus on optimizing the interaction between these layers to maximize throughput without compromising the overall integrity of the system.
