Definition ∞ A theoretical scaling solution for blockchains that involves creating a hierarchical structure of nested layers, each capable of processing transactions independently while periodically settling back to a higher layer. This approach aims to achieve massive transaction throughput by distributing computational load across many smaller, interconnected chains. It allows for parallel execution and specialized processing at different levels of the network. This method offers significant potential for increasing capacity.
Context ∞ The discussion around fractal scaling is prominent in research for advanced blockchain architectures, particularly those seeking to overcome current throughput limitations. A key debate involves the complexity of coordinating state transitions between numerous layers and ensuring data availability across the entire structure. Critical future developments include practical implementations and security proofs for these highly layered scaling designs.
