The booming development of Web3 has generated massive data storage demands. On-chain data for NFT assets, in-game items, DeFi smart contracts... all of these require a reliable "storage home." But the reality is clear: centralized cloud storage carries the risk of single points of failure, while existing decentralized networks often struggle with cost, performance, or compatibility with blockchain.

So how should one choose? This question has long puzzled Web3 developers.

The idea behind WAL protocol is quite interesting—it’s not simply a storage layer, but a high-performance decentralized data availability (DA) layer. In other words, it aims to build a bridge between blockchain and the vast world of storage, enabling efficient communication between the two.

**What is the core pain point?**

There has always been a "curse" in the Web3 storage field: decentralization, low cost, and high performance—these three requirements seem never to be satisfied simultaneously. You either sacrifice performance to reduce costs, or increase performance at a high expense, or revert to centralized solutions.

The innovation of WAL lies in its modular design. Don’t try to solve all problems with a single network; instead, decouple functions like data storage, availability proof, and data retrieval, each handled by specially optimized sub-networks. What are the benefits of this approach? The system’s scalability instantly improves, allowing flexible adjustments based on actual needs, and no longer being bottlenecked by a single-layer performance constraint.

This architectural approach is becoming a new choice for many DeFi ecosystems and NFT applications.
