# Modularity

Powered by Celestia

Tuna Chain embraces Celestia as its data availability layer, underpinning its architecture with a modular design. This approach effectively addresses the data availability challenges associated with Layer 2 solutions.

Leveraging cutting-edge techniques such as 2D Reed-Solomon erasure coding and Namespaced Merkle Trees (NMTs), Tuna Chain creates a trust-minimised ecosystem. The result is a substantial reduction in transaction costs for end-users and a considerable boost in overall network efficiency.
