3. Architecture Overview
Osirium follows a modular architecture designed to bridge off-chain AI inference with on-chain validation. The system is composed of four key layers that interact in a seamless pipeline:
🧩 1. Prompt Layer
The user submits a prompt, either manually (via CLI/API) or programmatically (via external sources like X).
🧠 2. Inference Layer
The prompt is processed through an external LLM — currently Claude AI — which generates the response. The AI model is accessed off-chain via secure API and runs in a stateless, verifiable environment.
🔐 3. Attestation Layer
Once the output is received, it is:
Structured using the EIP-712 standard
Digitally signed by a registered MCP node (using its private EVM key)
Returned as a full attestation object (prompt, output, signature, signer)
⚖️ 4. Smart Contract Layer
The signed attestation can be sent on-chain and verified using:
Verifier.sol– validates the EIP-712 signatureMCPRegistry.sol– checks if the signer is a trusted MCP node Upon verification, the output becomes an on-chain trusted result usable by other contracts.
This architecture allows Osirium to serve as a decentralized gateway for injecting authenticated AI intelligence into smart contract systems.
