What is Walrus, and how is it different from IPFS and Arweave?
Walrus is a decentralized storage network built on the Sui blockchain. Data is erasure-coded into slivers and spread across many independent storage nodes. Each piece of data has a Blob object on Sui that records its blobId and expiry, and the storage term can be extended before it ends.
Unlike IPFS, Walrus storage is paid for a term and kept by the network, so you don't have to find nodes to pin your data. Unlike Arweave, Walrus is paid by duration and renewable rather than a one-time payment for permanent storage. Walrus doesn't encrypt data itself; Onchain Drive encrypts it in your browser before upload and adds wallet login, USDC/SUI payments, sharing and renewals.
