The Data Storage Revolution in the Web3 Era: From Decentralization to Independent Data Availability Layer

With the rapid development of the data economy, everyone inevitably participates in various data storage activities. The arrival of the Web3 era promotes the gradual upgrading or transformation of most technology fields in the coming years. As a key infrastructure of Web3, Decentralization storage will expand more application scenarios in the future, including the data storage networks behind social data, short videos, live broadcasts, and smart cars.

In the Web3 era, data has become a core asset, and users owning their data is a key feature. Ensuring that users securely own their data and the assets it represents, while alleviating ordinary users' concerns about asset security, will help attract more users into the Web3 ecosystem. An independent data availability layer will become an indispensable part of Web3.

From Decentralization Storage to Data Availability Layer

Traditional centralized cloud storage methods can no longer meet current market demands. As users' requirements for personal information security and data storage continue to rise, especially following data breach incidents at some large data operators, the drawbacks of centralized storage have become increasingly apparent. The advancement of the Web3 era and the development of blockchain applications have made data more diverse, with expanding scale, and the dimensions of personal network data are more comprehensive and valuable, making data security and privacy protection even more important.

Decentralization storage has emerged as one of the earliest and most关注的 infrastructures in the Web3 field. Compared to traditional cloud storage, decentralization storage follows the principles of the sharing economy, utilizing massive edge storage devices to provide services, and project parties cannot control this data. The core advantage of decentralization storage is that users can control their own data, and in a system without centralized control, the security factor of the data is relatively high.

Currently, there are mainly two types of decentralized storage projects: one aims to generate blocks and uses storage for mining, but this may lead to slower storage and download speeds; the other uses one or several centralized nodes for verification, but there is a risk of single point of failure.

The emergence of the Data Availability (DA) layer addresses the issue of how light nodes can efficiently ensure data availability and accuracy without participating in consensus. An independent data availability layer effectively avoids single points of failure and maximizes data security. In addition, Layer 2 scaling solutions such as zkRollup also require the use of data availability layers to ensure that the Layer 2 network state can still be restored under extreme conditions, preventing user assets from being locked.

Analysis of Independent Data Availability Layer

Celestia

Celestia provides an independent DA blockchain, featuring a series of validator nodes, block producers, and consensus mechanisms to enhance security levels. Layer 2 publishes transaction data to the Celestia main chain, where validators sign the Merkle Root of the DA Attestation and send it to the DA Bridge Contract on the Ethereum main chain for verification and storage. Celestia adopts an optimistic proof mechanism, which is highly efficient when the network is operating normally.

MEMO

MEMO is a next-generation, high-capacity, high-availability enterprise-level storage network based on blockchain peer-to-peer technology. MEMO achieves decentralized, multi-to-multi storage operations and controls various key operations of the system through a smart contract. MEMO utilizes erasure coding and data recovery technologies to enhance storage capabilities, improve data security, and increase storage download efficiency.

MEMO introduces the Keeper role to prevent nodes from malicious attacks, maintaining economic balance through mutual checks among multiple roles. This system supports high-capacity, high-availability enterprise-level commercial storage, providing secure and reliable cloud storage services for NFTs, GameFi, DeFi, SocialFi, etc., and is compatible with WEB2, representing the perfect integration of blockchain and cloud storage.
