When teams are building a dApp, storage usually feels like a problem for later.
Everything works fine at first, so offchain data doesn’t get much attention. Walrus is a decentralized storage protocol used when applications start handling real user data like NFT metadata, images, or app content that needs to stay available long term.
This matters because once users rely on an app daily, losing data feels the same as the app failing, even if the smart contracts are fine.
