Artificial Intelligence is rapidly reshaping nearly every corner of the internet, and Web3 is no exception. As blockchain networks mature, a new challenge emerges: how do you let AI applications process sensitive data onchain without compromising privacy, security, or compliance?

This is where COTI V2 steps in. More than just another Ethereum Layer 2, COTI is a privacy infrastructure for Web3. Its focus is on Decentralized Confidential Computing (DeCC) - enabling users, developers, and even AI agents to compute on sensitive data without exposing it. That capability is becoming critical as decentralized finance (DeFi), real-world asset (RWA) tokenization, and AI converge.

In this article, we'll explore what makes COTI V2 special, how it supports AI-driven projects like Arbus, NFA, CodeX, and COTIAgents, and why its privacy-first approach is key to the next wave of Web3 innovation.

The Privacy Layer That Powers AI

At its core, COTI V2 solves one of the hardest problems in blockchain: enabling private computation on public infrastructure. Traditional blockchains are transparent - which is great for trust, but a nightmare for use cases that require confidentiality.

COTI's answer is Privacy-on-Demand, powered by garbled circuits (GCs) - a cryptographic technique developed in collaboration with Soda Labs. GCs allow two or more parties to compute a function over their inputs without revealing those inputs to each other. The result: sensitive data stays encrypted while still being usable.

This approach is not just theoretical. COTI's design is lightweight and resource-efficient, meaning developers can integrate it into applications without adding prohibitive costs or delays. That makes it well-suited for AI and machine learning workflows, where models often need access to user data but must protect privacy.

As COTI CEO Shahaf Bar-Geffen explains:

COTI's AI Ecosystem: Key Projects

One of the best ways to understand COTI's role in AI is to look at how it is already being used by projects in its ecosystem. Here are some of the standout examples.

Arbus: Secure Market Intelligence for Web3

Arbus is focused on off-chain data analytics and AI-powered market intelligence. Its mission is to make off-chain data actionable for Web3 users, companies, and AI agents.

Normally, storing and sharing this type of data securely would require a centralized solution. But by integrating with COTI, Arbus can store its user-validated data directly on the COTI L2, removing the need for an external storage provider.

This has several benefits:

• Data Integrity: Users know the data they pay for hasn't been tampered with.
• Privacy: User identities and sensitive information remain confidential.
• Composability: Other dApps in the COTI ecosystem can safely build on top of Arbus' insights.

This combination of secure storage + AI insights is a powerful enabler for Web3 use cases ranging from trading strategies to real-world data validation for RWAs.

NFA: Gamified AI-Powered Trading Education

NFA sits at the intersection of trading, AI, and gaming - and has already attracted over 85,000 monthly users through its Telegram mini-app.

Here's how it works:

1. The app presents AI-curated trading signals to users.
2. Users can swipe right to take an opportunity (simulate a buy) or left to pass.
3. Points and in-app tokens (GT) reward engagement and learning.

What makes COTI critical here is front-running protection. Without privacy, onchain trades can be observed in the mempool and exploited by bots through MEV attacks. COTI's garbled circuits allow users to execute trades confidentially until they are finalized, preserving profitability for those who put in the effort to research their moves.

This will become even more crucial when NFA enables real-money copy trading. Successful traders will want their strategies shielded from outsiders until execution is complete and COTI provides that protection.

CodeX: No-Code Building Meets Privacy

CodeX is an AI-powered no-code platform that allows users to build and deploy decentralized apps without writing heavy code. Its integration with COTI ensures that all dApps built with CodeX can meet stringent compliance requirements like GDPR, HIPAA, and AML, while still benefiting from decentralized infrastructure.

But CodeX goes further than just no-code. It also allows users to create, trade, and deploy AI agents, making it a launchpad for intelligent automation. These agents could be used for everything from automated DeFi strategies to supply chain monitoring - all while operating in a privacy-preserving way thanks to COTI.

COTIAgents: Open-Source AI Tooling

COTIAgents recently restructured into a research-driven lab focused on the intersection of AI and blockchain. Their mission is to build open-source tools and already COTI agents build open-source tools and software for the community, including :

• AI Tools 
• COTI Tool Suite
• Zinko Studio

This commitment to open-source-first development aligns with COTI's vision of building shared infrastructure for Web3. By making these tools public, COTIAgents ensures that even projects outside the COTI ecosystem can adopt privacy-first best practices.

Why COTI Matters for AI

AI is only as good as the data it has access to. But in a decentralized world, sharing that data is risky without proper safeguards. COTI makes it possible to compute on private data in a trustless way. That means:

• AI models can be trained on sensitive datasets (like medical data or financial transactions) without leaking private details.
• Machine learning predictions can be generated confidentially, ensuring that outputs aren't reverse-engineered to reveal inputs.
• DeFi protocols can incorporate AI risk models without exposing user portfolios to competitors.

This privacy-first approach is critical for unlocking new Web3 use cases. Without it, AI in crypto risks being limited to only public, non-sensitive data - which greatly reduces its potential impact.

Challenges and Risks

No infrastructure is perfect, and COTI faces challenges as it scales:

1. Adoption Curve: Privacy layers require developer education and integration work. Convincing projects to build on COTI will take time and incentives.
2. Regulatory Uncertainty: Privacy tools in crypto are often scrutinized by regulators. COTI's compliant approach (built to work within existing frameworks) is an advantage, but it still faces potential headwinds.
3. Competition: Other privacy solutions like zk-SNARKs and TEEs (Trusted Execution Environments) are also vying for market share. COTI's efficiency will be key to staying ahead.

Despite these challenges, the need for privacy-preserving computation is only growing - which plays in COTI's favor over the long run.

The Bigger Picture

AI and Web3 are converging faster than most expected. From AI-driven DeFi to tokenized real-world assets to fully autonomous onchain agents, the future will be powered by data - and that data will need to be protected.

COTI is not just building a Layer 2 - it is laying down the privacy rails for this next era of the internet. By making confidential computing accessible, efficient, and developer-friendly, COTI is positioning itself as a foundational layer for AI in Web3.

Final Thoughts

COTI V2 represents a major step forward for privacy infrastructure in blockchain. Its ability to deliver Privacy-on-Demand through garbled circuits, combined with its growing AI ecosystem, makes it one of the most important projects to watch in this space.

As more projects like Arbus, NFA, CodeX, and COTIAgents go live and integrate with COTI, we can expect to see a richer ecosystem of privacy-preserving, AI-enabled applications. This is more than just a technical evolution - it is a redefinition of how users will interact with data in Web3, balancing openness with security.

The future of AI onchain will require infrastructure that respects privacy, scales with demand, and complies with regulation. COTI V2 checks all three boxes.
