In Web3, storage solutions are evolving, but privacy remains a challenge. Traditional blockchains prioritize full transparency to guarantee immutability, but this has discouraged institutional investors who cannot risk exposing sensitive data. Walrus addresses this with Seal, a decentralized confidential management system built on Walrus.
Unlike Web2 storage, where privacy relies on trusting administrators, Seal ensures nodes cannot see your data at all. Using threshold encryption, files are split into fragments, and decryption keys are divided among multiple nodes. No single node can reconstruct the key, keeping your data fully encrypted even on a public network. The Sui blockchain manages access via smart contracts, enabling secure use cases like selling AI training data or storing auditable company records—all while maintaining privacy.
Walrus also redefines ownership. Instead of storing large files off-chain and pointing to them with NFTs, files become native on-chain objects via Sui’s object model. Transferring a file now transfers its actual data rights, not just a pointer.
The WAL token incentivizes long-term storage: fees are pooled in a storage fund and released gradually, rewarding nodes for sustained participation. This mechanism ensures data persistence in a decentralized environment, though it comes with the inherent risks of volatile token economics.
Walrus creates a “public yet private” network where data is decentralized, secure, and truly owned—aligning technical innovation with real-world privacy and ownership needs.
