The L2 Roadmap

Layer 2 scaling is not a finished product — it is an evolving stack of execution layers, proof systems, and data availability upgrades on Ethereum. Understanding where things are headed helps you evaluate new chains and separate durable trends from marketing hype.

Full danksharding will spread data across the validator set using PeerDAS, making rollup data posting dramatically cheaper without requiring every node to download everything. Combined with improving ZK provers, the cost gap between L1 and L2 should keep narrowing.

The long-term vision is a mesh of rollups — optimistic and ZK, general and app-specific — all settling to Ethereum as a shared security and data layer. Users may not think about which L2 they are on; bridges and intent-based systems route activity behind the scenes. Ethereum scales by adding layers, not by sacrificing what makes it worth building on.
