Walrus aims to fix a quiet, structural weakness of many blockchains: they reliably agree on state but do not guarantee durable, cheap, verifiable storage of large blobs. Walrus solves this by treating data availability as a decentralized, encoded storage market: split and erasure-code the blob (so only a subset of shards is needed to recover), use compact availability sampling so verifiers don’t have to download whole payloads, and back the system with a functional token that pays storage and enforces uptime. In short: durable blob storage + verifiable availability sampling + tokenized economic incentives for long-term serving.
