Layer 3 Rollups

Architecture

Layer 3 rollups represent a further abstraction of scaling solutions built upon Layer 2 rollups, aiming to enhance throughput and reduce transaction costs even further. These systems typically employ a recursive structure, where a Layer 3 rollup operates on top of a Layer 2 rollup, inheriting its security and leveraging its existing infrastructure. The design often incorporates data availability solutions, such as Validium or Volition, to optimize for specific use cases, balancing security with performance. Consequently, Layer 3 rollups offer a modular approach to scaling, allowing for customization and specialization within the broader Ethereum ecosystem.
