🏗️ Walrus × Sui Network: Deep Integration Analysis🏗️ Walrus × Sui Network: Deep Integration Analysis
The Sui Stack Architecture
Walrus launched on mainnet in 2025, adding a new foundational layer to the Sui Stack: decentralized storage built for scale, integrity, and programmability (CoinGecko) . The Sui Stack is a complete, end-to-end decentralized development framework consisting of four interconnected layers:
🔷 The Four Pillars of the Sui Stack
1️⃣ Sui Blockchain - Execution Layer
Fast Finality: Mysticeti v2, Sui's consensus engine, brought fast, sub-second finality to transactions across the Sui network (CoinGecko)
Parallel Processing: Object-based architecture enables transactions to process in parallel without competing for shared resources
Smart Contract Platform: Built on Move programming language for security and composability
2️⃣ Walrus - Decentralized Storage Layer
Content-Addressed Storage: Data stored on Walrus is content-addressed, versioned, and cryptographically verifiable, with tamper-evident history (CoinGecko)
Programmable Data: Instead of treating data as something external to Web3 apps, Walrus makes large-scale data a native, verifiable resource that apps can depend on (CoinGecko)
Storage Proof: Sui manages metadata, proofs and payments. Storage resources are tokenized, enabling programmable ownership and trading (CryptoRank.io)
3️⃣ Seal - Access Control Layer
Programmable Encryption: With Seal, builders can define who can access data, under what conditions, and for how long, with enforcement tied directly to onchain access policies (CoinGecko)
Conditional Decryption: Seal encrypts information that becomes decryptable only when specific blockchain conditions trigger (Gate)
Privacy Features: Seal introduced encrypted permissions for decentralized data in September 2025 (CoinGecko)
4️⃣ Nautilus - Verifiable Offchain Compute
Trusted Execution Environments (TEEs): Nautilus deployed trusted execution environments for verifiable off-chain computation (Gate)
Hybrid Applications: Nautilus provides this layer for the Sui Stack by enabling hybrid applications to work with data that originates outside of Sui, while still grounding it in verifiable logic and history (CoinMarketCap)
Current Support: AWS Nitro Enclaves with more TEE providers planned
🔗 Integration Mechanisms
Native Sui Integration
Move Smart Contract Control: Developers can now use Move smart contracts to control data storage, access permissions, and monetization rules (Gate)
Coordination Layer: Sui serves as the global coordination layer, Walrus plays a critical role as the data layer to ensure the transparency and auditability of outcomes, and Sui Nautilus powers verifiable offchain inferences (DropsTab)
Composability: Because Walrus data lives on Sui, it composes with the rest of the Sui ecosystem. Apps can mix and match on-chain code and off-chain storage seamlessly (Kraken)
Technical Architecture
RedStuff 2D Erasure Coding: Using RedStuff 2D erasure coding, even if many shards are offline, files can be reassembled quickly with minimal replication overhead (Kraken)
Byzantine Fault Tolerance: Walrus tolerates up to 1/3 malicious nodes, a leap over competitors like Filecoin (CryptoRank.io)
Cost Efficiency: Instead of checking individual files, Walrus audits entire nodes, slashing costs by 80% compared to traditional methods (CryptoRank.io)
💡 Real-World Integration Examples
Sui Stack Messaging SDK
The Messaging SDK is built directly on the Sui Stack, combining execution on Sui, durable storage through Walrus, and programmable access control via Seal. It gives builders a native way to send structured messages to wallets and applications based on onchain state and object interactions (CoinGecko)
How it works:
Messages created and verified onchain (Sui)
Stored securely and durably (Walrus)
Shared according to explicit permission rules (Seal)
Walrus Sites
Walrus Sites, decentralized websites powered by Walrus, serve both as a developer tool and a concrete example of what Walrus enables. Built using the same primitives available to the ecosystem, they provide a model for hosting decentralized frontends without relying on centralized hosting infrastructure (CoinGecko)
Capabilities:
Fully decentralized websites with no centralized hosting
All resources (HTML, CSS, JS, media) stored on Walrus
Governance via Sui smart contracts
🤖 AI Infrastructure Integration
Verifiable AI Economy Stack
The Sui Stack comprises four interconnected components targeting specific challenges in AI deployment. Walrus serves as the data foundation layer, providing tamper-resistant storage with built-in provenance tracking (MEXC)
Complete AI Workflow:
Data Storage → Walrus (tamper-resistant, verifiable provenance)
Access Control → Seal (programmable encryption, usage parameters)
Computation → Nautilus (secure execution in TEEs)
Transactions → Sui (control, audit, receipts)
Nautilus × Walrus × Seal Integration
With Seal-gated files stored on Walrus, Nautilus enclaves can securely fetch encrypted data, process it inside a TEE, and send verifiable results onchain. The result? Verifiable compute, private data, and programmable access (CoinCodex)
Use Cases:
AI Agent Storage: With Walrus, Talus AI agents can seamlessly store, retrieve, and process data onchain—empowering developers to efficiently build, deploy, and scale AI agents (KuCoin)
Secure Model Training: Encrypted datasets accessible only to verified TEEs
Privacy-Preserving Analytics: Process sensitive data without exposing it
📊 Integration Performance Metrics
Network Statistics (as of recent data)
Data Stored: Walrus has already stored 440+ TB of data (Ainvest)
Token Usage: 500M+ WAL used for staking and operations (Ainvest)
Durability: Storage durability via erasure-coded distribution with 5x overhead and ⅔ node fault tolerance (Ainvest)
Developer Benefits
Unified Gaming Infrastructure: Game developers benefit from unified storage for game states and media assets on the same programmable layer (Gate)
Full-Stack dApps: Frontend applications can operate under governance from the same smart contracts managing backend logic (Gate)
Seamless Integration: Use Sui's CLI, HTTP APIs, or tools like SuiS3 (an AWS S3-style interface for Walrus) (CryptoRank.io)
🎯 Strategic Integration Use Cases
1. DePIN (Decentralized Physical Infrastructure)
DLP Labs: DLP Labs integrated the Sui Stack (Sui, Walrus, and Seal) to convert electric vehicle (EV) data into user-owned economic assets, aiming to reduce the total cost of EV ownership (CoinMarketCap)
2. Decentralized AI Training
Yotta Labs: Walrus as dedicated data layer for decentralized AI storage and workflow management
3. NFT Infrastructure
Dynamic NFTs: As Daniel Fritsche noted, Sui enables dynamic and composable NFTs, which dramatically open up the possibilities of NFT use cases. Add in programmable storage, and the attached NFT metadata becomes just as dynamic and responsive (CryptoRank.io)
4. Blockchain History Archival
Walrus can be used as a lower-cost decentralized store to store blockchain history. For Sui, this can include sequences of checkpoints with all associated transaction and effects content, as well as historic snapshots of the blockchain state, code, or binaries (Crypto.com)
🚀 2026 Integration Roadmap
Based on Walrus's strategic direction:
Deeper Sui Stack Integration - In 2026, we'll be integrating with the network even more closely, so your blockchain and your data layer can communicate seamlessly (CoinMarketCap)
Enhanced Privacy Features - Privacy and access controls are critical for the growth of decentralized data, especially for DeFi, data markets and AI. We plan to focus even more on empowering private, verifiable data workflows (CoinMarketCap)
Developer Experience - We want using Walrus to be as simple as using any Web2 infrastructure tool. Expect new features that make Walrus even more powerful and easy to use (CoinMarketCap)
📈 Bottom Line
Walrus isn't just "storage for Sui" — it's a core architectural component of the most complete Web3 development stack available. The tight integration across all four layers (Sui, Walrus, Seal, Nautilus) enables use cases that are impossible on other blockchains:
✅ True decentralization - frontends and backends both onchain
✅ Programmable data lifecycles - storage managed by smart contracts
✅ Privacy-preserving compute - encrypted data processed in TEEs
✅ Verifiable AI infrastructure - complete data → compute → transaction pipeline
The synergy between these components positions Sui + Walrus as the infrastructure backbone for the next generation of decentralized applications, particularly in AI, gaming, and enterprise data markets
