🛠 How It Works

1️⃣ Cryptographic Proofs for AI Verification

DeepTrust Protocol ensures the authenticity and reliability of AI models through cryptographic proofs, specifically zero-knowledge proofs (ZKPs) and session hashes. Traditional AI systems require users to trust that the model has not been tampered with. However, in decentralized environments, there must be a way to verify AI model integrity without revealing sensitive information.

DeepTrust addresses this by using ZKPs to prove AI model correctness while maintaining privacy. These proofs allow AI nodes to demonstrate that their responses are generated by an unaltered and approved model, without revealing the inner workings of the model itself. This is critical for proprietary AI services that wish to maintain confidentiality while still providing verifiable and trustworthy outputs.

Additionally, DeepTrust logs AI interactions as session hashes. Each AI query and response is stored as a cryptographic hash, ensuring that records cannot be manipulated. This method allows validators to verify AI interactions without exposing private user data, providing both security and transparency.


2️⃣ Merkle-Based Session Verification

One of the biggest challenges in AI governance is ensuring that AI responses are verifiable and immutable without compromising privacy. A simple approach would be to store all AI interactions on-chain, but this is impractical due to high storage costs and privacy concerns.

To solve this, DeepTrust uses a Merkle tree structure for session verification. A Merkle tree is a data structure that enables efficient and secure verification of large datasets. In the context of DeepTrust, each AI interaction (input, processing, and output) is recorded as a hash, and these hashes are arranged in a Merkle tree. The root of this tree is stored on-chain, providing an immutable fingerprint of all AI transactions.

If a dispute arises regarding an AI-generated response, validators can use the Merkle tree to efficiently verify whether a specific query-response pair was included in a session. This ensures that AI models cannot manipulate historical responses and that users have cryptographic proof of their interactions.


3️⃣ Scalable AI Computation on Arbitrum Orbit L3

Most blockchain networks are not designed to handle the high computational demands of AI applications. Running AI computations directly on Ethereum or other Layer-1 blockchains would be prohibitively expensive due to gas fees and slow transaction speeds. Even some Layer-2 solutions struggle with AI workloads because they are optimized for simple financial transactions rather than complex computations.

DeepTrust is built on Arbitrum Orbit L3, a specialized Layer-3 blockchain designed to provide high-speed, low-cost execution for AI-related transactions. Arbitrum Orbit L3 enables DeepTrust to process AI queries off-chain while only storing cryptographic proofs on-chain, significantly reducing costs and increasing scalability. This approach allows for: - Low transaction fees, making AI services economically viable. - High throughput, ensuring real-time AI model responses. - Cross-chain compatibility, enabling AI models to serve applications across different blockchains.

By leveraging Arbitrum Orbit’s rollup technology, DeepTrust achieves a balance between decentralization, efficiency, and scalability.


4️⃣ Reputation-Based AI Node System

A decentralized AI network requires a way to distinguish between reliable and unreliable AI nodes. Without a trust mechanism, bad actors could deploy AI models that provide biased, false, or malicious responses.

DeepTrust introduces a reputation-based system where AI nodes are continuously evaluated based on their past interactions and validations. Each AI node has a reputation score, which is determined by: 1. The accuracy of past responses, as verified by validators. 2. Stake-based incentives, where nodes must commit tokens to guarantee their behavior. 3. User feedback, collected from verified AI interactions.

If an AI node attempts to manipulate outputs or fails to provide verifiable proofs, its reputation score decreases, and in severe cases, its stake may be slashed. This reputation model ensures that high-quality AI nodes receive more queries, while bad actors are gradually removed from the network.


5️⃣ Zero-Knowledge Proofs for Privacy & Compliance

A major challenge in AI governance is ensuring that AI models can be verified without exposing proprietary information. In traditional AI systems, users must choose between trusting a black-box model or revealing sensitive training data.

DeepTrust leverages zero-knowledge proofs (ZKPs) to allow AI models to prove their legitimacy without disclosing how they function. This ensures: - Privacy: AI models can be used in sensitive applications (finance, healthcare) without exposing proprietary data. - Regulatory Compliance: Enterprises can prove compliance with GDPR, HIPAA, and other privacy regulations without revealing confidential data. - Trust Without Transparency: AI providers can offer services without revealing their intellectual property, ensuring fair competition.

These proofs are generated in real-time as AI models interact with users, ensuring that each response is genuine and untampered.


6️⃣ Secure AI Interactions Using Off-Chain Computation

On-chain AI computation is expensive and impractical. However, off-chain AI computation introduces trust issues, as users cannot be sure whether an AI model is executing correctly without verification.

DeepTrust solves this problem by executing AI computations off-chain while maintaining verifiable proofs on-chain. This approach ensures: - Cost-efficiency, as AI models do not require expensive blockchain execution. - Security, as session hashes provide an immutable record of AI interactions. - Speed, since AI models can operate in real-time without waiting for blockchain confirmations.

Users interact with AI services privately, with only cryptographic fingerprints of their interactions being recorded on-chain.


7️⃣ Multi-Layer Governance for AI Customization

AI applications serve different industries, each with its own governance requirements. A one-size-fits-all governance model is impractical for AI regulation, as financial institutions require different AI controls than decentralized applications (dApps) in gaming or art.

DeepTrust offers a multi-layer governance system that includes: 1. Protocol Governance: Ensures the overall security and decentralization of the network. 2. Application Governance: Allows organizations and industries to implement custom AI governance rules for their specific needs. 3. Validator Oversight: Provides independent verification of AI models and their interactions.

This model allows regulated industries, enterprises, and decentralized communities to tailor AI governance to their specific requirements.
