Architecture Overview

Core Infrastructure

Blockchain Layer: Sui testnet provides the foundational blockchain infrastructure for smart contracts, transaction processing, and immutable record keeping.

Storage Layer: Walrus distributed storage network handles large file storage with built-in redundancy and fault tolerance.

Security Layer: SEAL (Simple Encrypted Arithmetic Library) provides homomorphic encryption capabilities for secure computation on encrypted data.

Verification Layer: TEE attestation through Nautilus server ensures model integrity and authentic execution environments.

Frontend Layer: Next.js 15 application with TypeScript provides the user interface and client-side functionality.

Data Flow Architecture

1. Model Upload: Files encrypted with SEAL, stored on Walrus, metadata recorded on Sui
2. TEE Verification: Models processed in secure enclaves with cryptographic attestation
3. Marketplace Listing: Smart contracts manage pricing, access control, and ownership
4. Purchase Flow: SUI cryptocurrency payments with automatic escrow and release
5. Access Control: Policy-based decryption keys managed through SEAL infrastructure
