Topia aims to bring an shared data availability layer to Ethereum's rollup and to connect data availability for thousands of future rollups!

Unlike other DA projects which create a DA for their own blockchains, Topia is creating a shared DA layer for all future Ethereum rollups. Therefore, Topia will seamlessly integrate with Ethereum's mature rollup and developer ecosystem.

Topia provides a native solution for cross-chain communication. Topia's future vision is to achieve two phases of goals for the Ethereum ecosystem:

First, to provide a shared DA layer specifically optimized for Ethereum rollup; Second, to enable data communication between rollups, realizing "Rollup Data Interconnection"

On top of Topia's data interconnected shared DA layer network, unique "cross-rollup data applications" will grow, ranging from blockchain games, to NFT and NFT exchanges across all rollups, to social media, personal data markets and and so on.

Imagine, your blockchain game equipment data on Arbitrum can be seamlessly used on Scroll; your personal credit data accumulated on OP can be seamlessly invoked on ZKSync.

Rollup data will no longer be independent rivers but a fully circulating ocean, and Topia is the vital canal connecting all rollup data rivers :)
