What are layer 3 blockchains?
Layer 3 blockchains are advanced protocols built on existing Layer 2 solutions, providing interoperability and application-specific functions. They aim to further enhance scalability, support complex dApps, and enable customization, while inheriting the security of Layer 1 blockchains. Examples of Layer 3 protocols include Orbs, Arbitrum Orbit, and zkSync Hyperchains.
