Background Two years ago, at the beginning of the rise of the modular blockchain narrative, we wrote an article presenting our views and predictions on the Data Availability (Data Availability) circuit. As we anticipated, the modular blockchain narrative has prevailed and fueled infrastructure innovation, enhanced network interoperability, and promoted more collaboration and integration within the ecosystem, and various Rollup as a Service (RaaS) solutions (Altlayer, Caldera, Conduit, Gelato) have begun to emerge. The following figure shows the interface of the Rollup development tool Conduit, showing that deploying Rollup and selecting DA solutions has become extremely simple and convenient. Source: Conduit In the past two years, alternative DA solutions (Alt-DA) such as Celestia, Eigenda, Avail, and Nearda have developed significantly, each showing unique technical advantages and market share. At the same time, with the launch of Ethereum EIP-4844, the introduction of blobs to replace calldata greatly reduced the cost of using Rollup in Ethereum's native DA layer. Today, developers and project parties face more trade-offs when choosing a data availability layer. This article will track and analyze existing DA solutions, explore in depth their performance costs, technical characteristics and market performance, and present our views and thoughts on future DA circuit development. 1. The current DA solution's rollup, which uses Ethereum's native DA on-chain solution, mainly focuses on mainstream Layer 2 solutions that have been updated from CallData storage to suit BLOB, including Arbitrum, Optimism, and Base, as well as Starknet, zkSync, and Scroll. By using Ethereum as the DA layer, Rollup data is verified and stored by all Ethereum nodes, and benefits from Ethereum's security, degree of decentralization, continuity of protocol upgrades, and economic incentives. Comprehensive L2 occupies an important position in the Ethereum ecosystem, and requires the use of the above orthodoxy brought about by native DA as the core difference. (Vitalik believes that the core of Rollup is an unconditional security guarantee: you can take out your assets even if everyone is against you. (If data availability depends on an external system, this equivalent security cannot be obtained) However, publishing data to the Ethereum mainnet was associated with high costs, especially before EIP - 4844 (calldata cost was 16 gas per byte; in December 2023 alone, L2 spent more than 15,000 ETH on DA costs). As a result, various Alt-DA off-chain solutions have emerged, such as Celestia, Eigenda, and Avail, which is not yet online. Through various technical means, such as DAS, erasure codes, KZG promises, etc., the cost of data storage and transmission has been reduced. Among these, Celestia, as a modular blockchain dedicated to DA, has become the leading project on the DA circuit since the main network was launched in October 2023. The main target customers include projects requiring a modular architecture: cross-chain bridges, settlement layer solutions, defi projects, games, sequencers, and Layer 2 solutions not limited to the Ethereum ecosystem. Its current customers include Omnichain DEX protocol Orderly, modular L2 Manta Pacific tailored for EVM-native ZK applications, Base-based L3 Hokum, and DEX Lyra and Aevo, which focus on derivatives trading. As a DA layer pioneer in modular design that is not limited to a specific ecosystem, Celestia's advantages make it the first choice for many emerging Layer 2 projects. EigenDA was developed by EigenLabs and uses EigenLayer's restaking mechanism to provide an efficient, secure, and scalable DA service solution, inheriting to some extent the security of the Ethereum main network and a huge validator network. eiGenda focuses on providing high performance to the Ethereum ecosystem...
