# 2.4 Settlement and Data Availability on Base

While execution and proof generation occur at Layer 3, Base (Layer 2) serves as the immutable settlement and data availability anchor for the RealmScale ecosystem.

Aggregated proofs are submitted to a Verifier Contract deployed on Base. The contract verifies the recursive proof and updates the canonical state commitment of the RealmScale world. This ensures that the final state inherits the same security properties as Base itself.

For data availability, RealmScale utilizes EIP-4844 (Proto-Danksharding) blobs on Base to publish state deltas and execution metadata. By separating execution data from permanent storage, the protocol keeps on-chain costs minimal while maintaining auditability and replayability. Observers can reconstruct the evolution of the game world without requiring full execution logs to be stored on-chain indefinitely.

Assets minted or managed within RealmScale—such as NFTs or in-game resources—are ultimately settled on Base, ensuring compatibility with the broader Ethereum ecosystem. This design allows seamless interoperability with DeFi protocols, marketplaces, and cross-chain infrastructure without exposing game execution to EVM constraints.
