5.Huobi Research Institute Analysis
As the blockchain ecosystem evolves, the cost to use Ethereum has remained high. The scaling solution, Rollup, requires uploading compressed transaction data to the Ethereum mainnet for data availability (DA), which incurs on-chain storage costs that remain above ideal levels. To meet demand for Rollup data availability and cost reduction, there have been attempts to build an independent DA network.
The DA network ensures that Rollup's transaction data is consistent with the data in its network, under the surveillance of the Ethereum veriifier and its own full nodes. It also confirms that this data is published in its network through light node sampling verification and uses data availability attestation to convince Ethereum that the DA network has stored and published the data.
While the DA layer will encounter competition from EIP-4488 and EIP-4844 in the short term, its adoption and ability to generate relatively stable cash flow appears feasible in the long term due to its strong scalability.
From a broader perspective, the data availability layer is the latest step in the modularization process of blockchain, which forms a structure of "consensus-execution-data availability" separated from each other. Due to the trilemma of blockchain, the best way to improve scalability, while ensuring a high degree of decentralization and security, is to reduce the tasks of the mainnet and access additional execution layers, followed by a separate DA layer.
This has the advantage of making the performance of the whole greater than the sum of the parts by dividing the work. Modularized blockchains may better meet expectations in terms of performance and cost over time, and in turn lead other public chains to embrace modularity.
