DA Ecology and Competitive Landscape

Two years ago, at the beginning of the modular blockchain narrative, we wrote an article proposing our views and predictions on the Data Availability track. As we expected, the modular blockchain narrative has taken hold and driven infrastructure innovation, enhanced network interoperability, and fostered more collaboration and integration within the ecosystem, with various Rollup-as-a-Service (RaaS) solutions (Altlayer, Caldera, Conduit, Gelato) started to emerge. The figure below shows the interface of the Rollup development tool Conduit, showing that deploying Rollup and selecting a DA solution have become extremely simple and convenient.

In the past two years, alternative DA solutions (Alt-DA) such as Celestia, EigenDA, Avail, and NearDA have achieved significant development, each demonstrating unique technical advantages and market share. At the same time, with the launch of Ethereum EIP-4844, blobs are introduced to replace calldata, which greatly reduces the cost of using Rollup in the native DA layer of Ethereum. Nowadays, developers and project parties face more trade-offs when choosing the data availability layer. This article will track and analyze existing DA solutions, deeply explore their performance costs, technical characteristics and market performance, and propose our views on the future DA track. Developmental perspectives and reflections.
