At the core of Walrus is Red Stuff, a two-dimensional erasure
coding protocol that achieves high security with only 4.5x repli-
cation factor, while enabling self-healing recovery that requires
bandwidth proportional to only the lost data (𝑂(|𝑏𝑙𝑜𝑏|/𝑛) versus
𝑂(|𝑏𝑙𝑜𝑏|) in traditional systems). Crucially, Red Stuff is the first
protocol to support storage challenges in asynchronous networks,
preventing adversaries from exploiting network delays to pass ver-
ification without actually storing data.
Walrus also introduces a novel multi-stage epoch change proto-
col that efficiently handles storage node churn while maintaining
uninterrupted availability during committee transitions. Our sys-
tem incorporates authenticated data structures to defend against
malicious clients and ensures data consistency throughout stor-
age and retrieval processes. Experimental evaluation demonstrates
that Walrus achieves practical performance at scale, making it
suitable for a wide range of decentralized applications requiring
high-integrity, available blob storage with reasonable overhead. #walrus $WAL @WalrusProtocol
