Layer 3 Scaling Solutions
Layer 3 scaling solutions are advanced blockchain architectures built on top of Layer 2 scaling solutions to provide additional scalability, functionality, and specialized execution environments. These solutions create a third layer of abstraction that can optimize for specific use cases while inheriting the security properties of underlying layers.
Understanding Layer 3 scaling solutions
Layer 3 solutions represent the next evolution in blockchain scaling architectures, building upon the foundation of Layer 1 (base chains) and Layer 2 (rollups and sidechains). These solutions typically focus on specialized functionality such as privacy, application-specific computations, or cross-chain interoperability.
