One of the most misunderstood parts of onchain architecture is the difference between transaction data and application data. Walrus is not built to replace blockchains or store simple transaction records. Its purpose is to store large application objects that are impractical to keep directly onchain, such as NFT metadata files, media assets, and long-lived application state.
These objects are critical to how many applications function, yet storing them onchain is costly and inefficient. Walrus provides a decentralized way to store this data while allowing smart contracts and applications to reference it securely. This keeps contracts lightweight while preserving access to the data they depend on.
Without a system like Walrus, many projects rely on centralized storage services, creating long-term risk. Walrus addresses this by aligning data storage with decentralization principles, making application data more durable over time.
