Walrus: An Efficient Decentralized Storage Network

Fri, Jun 20, 2025, 12:30 PM · 25:41

Decentralized storage systems face a fundamental trade-off between replication overhead, recovery efficiency, and security guarantees. Current approaches either rely on full replication, incurring substantial storage costs, or employ trivial erasure coding schemes that struggle with efficient recovery especially under high storage-node churn. We present Walrus: a novel decentralized blob storage system that addresses these limitations through multiple technical innovations.
