Definition ∞ Decentralized applications (dApps) operating on Layer 3 protocols, which are built atop Layer 2 scaling solutions that themselves sit on a Layer 1 blockchain. These applications leverage the enhanced scalability, specialized functionalities, and potentially lower transaction costs offered by these multi-layered architectures. L3 dApps aim to deliver highly performant and customized user experiences. They represent a further abstraction layer for decentralized services.
Context ∞ The discussion surrounding L3 dApps is emerging as blockchain ecosystems mature and seek to address specific application needs beyond general-purpose Layer 2s. A key debate involves the complexity of developing and maintaining applications across multiple layers and the security implications of such deep layering. Future developments will likely focus on developer tooling and standardized frameworks to simplify the creation and deployment of these advanced decentralized applications.
