Since the mainnet launch in 2025, Walrus has become a key infrastructure in the Sui ecosystem. It not only handles routine needs such as large file blob storage, AI dataset support, and NFT permanent archiving but also manages blockchain history records and private data storage—things that are virtually impossible under traditional centralized architectures.

The turning point came in January this year. After the release of Sui's Verifiable AI framework, Walrus directly took on the role of an on-chain transparent storage layer. How important is this position? It enables AI systems to achieve true data verifiability, traceability, and even data monetization. In other words, those Web3 features once only imagined are now turning into actionable technical solutions.

How does the underlying technology achieve this? Essentially, it’s the Red Stuff two-dimensional encoding mechanism. Its core idea is to split blobs into primary and secondary slivers, then replace computationally intensive mathematical operations with lightweight XOR operations. This significantly reduces encoding and decoding overhead. The replication factor only needs to be 4.5 times to ensure protection, compared to over 100 times for traditional full-replication schemes, and RS coding is not as efficient.

Even more impressive is its self-healing capability. Even if nodes experience Byzantine faults or network jitter causes nodes to drop out, data availability remains guaranteed. This is backed by the PoA (Proof of Availability) mechanism that incentivizes nodes to stay honest, along with vector commitments on the Sui chain that ensure data integrity. Write operations require at least 2f+1 correct slivers to succeed, while read operations can reconstruct data from partial fragments, combining BFT-level security with efficient recovery.

On the ecosystem side, actions are also frequent. Crossmint recently completed integration, providing Web3 developers with an out-of-the-box toolkit, especially suitable for AI agents and tokenization scenarios. Tusky is migrating data to Walrus to extend service longevity. The Pudgy ecosystem is also exploring integration... All these indicate that the value of the storage layer is gradually being validated and unleashed.
