Architecture Overview
The ORACULS stack powering TAG IT Network's product authentication infrastructure.
ORACULS Stack
TAG IT Network operates on a 6-layer hybrid public-private architecture designed for scalable product authentication, AI-driven verification, and cross-chain interoperability.
| Layer | Components | Responsibility |
|---|---|---|
| Applications | ORACULAR App (React Native), Admin Console (Next.js 14), Partner Portal, SDK | User-facing interfaces, scan/verify UX |
| Gateway | tagit-services (Express.js) | Auth, API routing, AI orchestration |
| Ledger (Public) | TAGIT L2 (OP Stack) + EigenDA | Asset identity, verification, governance |
| Settlement | Ethereum L1 | Escrow, timelocks, security backstop |
| Interop | Chainlink CCIP | Cross-chain messaging (ETH, Polygon, Arbitrum) |
| Private Ledger | Hyperledger Besu | Gov/mil data, PQC attestations |
