Walrus used an interesting technical approach to solve the problem of large file storage. The core idea is to perform erasure coding on the files, then fragment and disperse them across various nodes in a decentralized network—sounds complicated, but in reality, it simply enhances fault tolerance, so that if one or two nodes fail, the entire system can still operate smoothly.

Why can this approach reduce costs? Because it leverages the characteristics of blockchain networks, eliminating the premium charged by centralized service providers. Compared to traditional cloud storage that often costs hundreds of dollars per month, decentralized storage offers significant cost advantages through redundancy design and cryptographic encoding. Not only can individual users save money, but enterprise applications can also find more cost-effective solutions.

Security is even more noteworthy—since data is dispersed across multiple independent nodes, the risk of single-point attacks or data loss is greatly reduced. Coupled with encryption protection, it’s essentially like giving your files double insurance. This makes it a good choice for scenarios that require high data security.
