Modular Data Availability (DA) layers boost blockchain scalability by splitting data storage from execution, reducing congestion in chains like Ethereum. Solutions like Celestia and EigenDA cut costs—Celestia to $3.41/MB from Arbitrum’s $1980/MB—via Data Availability Sampling, enhancing verification and throughput. This supports cheaper Rollups and scalable networks. Celestia, built on Cosmos, targets中小型L2s with affordability, while EigenDA uses Ethereum’s security for bigger L2s. Both promise growth, despite Ethereum’s EIP-4844 rivalry. As of March 11, 2025, their flexibility signals strong market prospects in a multi-chain world.
