# How Transcend Works

Transcend ensures that every AI Agent action is cryptographically verifiable, leveraging state-of-the-art technology to deliver unparalleled transparency, trust, and reliability.

***

## **Trusted Execution Environment (TEE)**

AI Agents within Transcend operate in a Trusted Execution Environment (TEE), a secure enclave that isolates code execution and data storage from unauthorized access.

* **Enhanced Security**: The TEE prevents tampering and ensures that all actions are executed with integrity.
* **Uncompromising Trust**: By isolating sensitive operations, the TEE guarantees that no external forces can compromise the system’s functionality.

***

## **Proof Generation Workflow**

Every interaction within Transcend undergoes a rigorous verification process, ensuring cryptographic integrity at every step.

1. **Request and Response Hashing**
   * Each interaction is hashed using **SHA-256**, generating a cryptographic summary of the input and output data.
2. **Signature Creation**
   * The TEE digitally signs the hash with its private key, producing a tamper-proof signature unique to each action.
3. **Attestation**
   * **AWS Nitro Enclaves** validate the hash and signature, adding an additional layer of verification and trust.
4. **Immutable Storage**
   * All generated proofs are immutably stored on a **distributed ledger**, enabling future audits and ensuring complete transparency.

***

## **Proof Metadata**

Every action performed by an AI Agent on Transcend is accompanied by the following metadata:

* **Hash**: A unique fingerprint representing the input and output.
* **Signature**: A cryptographic seal ensuring the data's integrity.
* **Attestation Document**: Proof that the TEE executed the action in a secure environment.
* **Public Key**: Used to verify the signature and validate the action's authenticity.

## **Code Example: Proof Validation in Rust**

```rust
use transcend_sdk::{Proof, Validator};

fn main() {
    let proof = Proof::new(
        "action_hash",
        "agent_signature",
        "attestation_doc",
        "public_key"
    );

    let validator = Validator::new();
    match validator.validate(&proof) {
        Ok(valid) => println!("Proof is valid: {}", valid),
        Err(e) => println!("Proof validation failed: {:?}", e),
    }
}
```

## **Building Trust, One Proof at a Time**

By integrating robust cryptographic workflows and leveraging secure enclaves, Transcend ensures that every action, inference, and decision made by its AI Agents is not only reliable but verifiable.

Transcend doesn’t just operate—it proves.
