In the development of Web3, data storage has always been a critical bottleneck. The issue is very real: traditional decentralized storage solutions are either too costly or lack flexibility. The demand for storing large files such as AI large model training data, high-definition videos, and NFT metadata continues to grow, but existing solutions often fall short.

The Walrus protocol built on the Sui blockchain aims to solve this problem. Its core mission is clear—efficient storage of large binary objects (Blobs), providing a stable data infrastructure for Sui and cross-chain applications. This protocol was developed by Mysten Labs, with the Walrus Foundation responsible for governance.

In comparison, predecessors like Filecoin and Arweave hold market positions but have their limitations. Walrus’s approach is different—it emphasizes native integration with the Sui ecosystem, focusing on balancing programmability and cost efficiency. This means developers can more flexibly utilize storage capabilities without being deterred by exorbitant costs.

At the protocol level, Walrus introduces new technical architecture to optimize data availability and redundancy guarantees. Simply put, it aims to minimize operational costs while ensuring data security. This is particularly attractive for teams building NFT applications, on-chain games, or decentralized AI applications.

Looking at the ecosystem prospects, the demand for storage infrastructure in Web3 applications will only grow. Whether Walrus can become the mainstream choice for next-generation data infrastructure depends on its performance in real-world scenarios—especially in terms of cost competitiveness, stability, and developer experience.
