Walrus represents blobs as programmable objects in Move, making data a directly manipulable on-chain asset without middlemen for Sui smart contracts that need to conditionally release cash after validating storage and availability.
Walrus stores blob metadata—like its unique blob ID derived from its content hash, commitment hashes for erasure-coded slivers, exact size in bytes for fee calculations, and storage duration in epochs (typically 30 days each)—directly as dynamic Sui objects that Move smart contracts can query, update, or transfer. For example, a contract can call functions to check the Proo
Move modules allow developers to automate blob management by merging additional storage resource objects (acquired via Sui transactions paying in SUI but influenced by WAL staking yields) to extend epochs or conditionally deleting blobs by disassociating the ID from the resource object once certain events trigger, such as a time-locked condition or external oracle input, all while mai
WAL tokens allow holders to stake and delegate to storage nodes, where the node's sliver assignment and fee earnings are proportional to staked WAL amounts, allowing token holders to earn passive yields from storage fees while governance votes using WAL can adjust minimum PoA quorums or renewal fee structures, directly linking token utility to network data programmability and sustainability.
A game dev building on Sui uploads asset packs as blobs to Walrus, then uses a Move contract to link the blob object to an in-game NFT minting process that verifies PoA and metadata integrity before minting, ensuring players can access textures or models on demand without off-chain dependencies.
How would you arrange a contract to dynamically renew blobs based on user staking WAL tokens for prolonged data access when integrating Walrus into your Move-based dApp?
