Ethereum’s founder, Vitalik Buterin, has recently re-stated that the network was never intended to be just a financial tool, it was built to empower people, to decentralize authority, and to protect individual sovereignty. Ethereum was in fact created on the philosophical foundation to create systems that make users self-sovereign, resilient, and private by design, as set out in its Trustless Manifesto, 2025.
As the Ethereum ecosystem evolves, new layers and solutions strive to balance scale with principle. Yet, few have directly tied their mission to this foundational ethos. COTI steps into that gap, translating Ethereum’s liberating philosophy into code and functionality that builders and users can apply today.

COTI is an Ethereum Layer 2 dedicated to combining scalability and privacy without compromising decentralization. Its architecture responds directly to Buterin’s call to seek freedom and resist central points of failure.
How? Through its groundbreaking implementation of Garbled Circuits that deploys a powerful cryptographic protocol to allow developers to integrate private computation when and where needed, without requiring the entire network to become confidential. Users retain choice over what they disclose and when. This is a departure from the radical transparency that has characterized blockchain until now, offering privacy as essential infrastructure and a fundamental freedom.
Garbled Circuits: The Cryptography Behind Sovereignty
Garbled Circuits excels at secure multi-party computation (MPC) allowing smart contracts to operate on encrypted inputs without exposing the data. It can do this with unmatched performance: up to 3000x faster and 250x lighter than alternative privacy solutions.
Using COTI, dApp builders can design systems to handle sensitive information at scale such as financial data, user identities, or proprietary algorithms, without ever revealing them on-chain.
This means:
Users maintain control over their data while still participating fully in decentralized ecosystems.
Developers can build trustless products without relying on third-party intermediaries, using familiar language.
The network achieves censorship resistance, as no centralized entity can selectively restrict or monitor private computations, while remaining secured by Ethereum’s proven infrastructure.
Trustless Systems for a Trustless Future
Instead of depending on institutions or authorities, trust is rooted in mathematics and multi-party computation protocols. Through its system design COTI fulfills one of Ethereum’s core promises: to give people tools that make trust optional, not obligatory. Every transaction, interaction, and computation is programmable, and can be designed to occur, without revealing unnecessary information or creating points of vulnerability, opening new possibilities for use cases in finance, healthcare, identity management, supply chain, and real-world asset tokenization.
Aligning with Ethereum’s Core Values
Vitalik Buterin’s vision is a declaration of value. Ethereum, in its purest form, is a platform for human freedom expressed through decentralized coordination. COTI’s mission resonates deeply with this ideology, offering tools that make individual sovereignty in the digital realm a tangible reality.
COTI’s GC layer remains verifiable and secure even under adversarial conditions. Owing to its lightweight technology, COTI can run on any device, even mobile, offering developers the means to build dApps that are inherently resistant to censorship and control, applications that continue to function even if users or developers face external pressure. Launched on mainnet in 2025, COTI brings Ethereum’s idealism into practical, enterprise-ready infrastructure.
COTI is more than a scaling solution, it is a sovereignty solution. It transforms Ethereum’s idealism into actionable infrastructure, ensuring that the next generation of applications can truly set people free.
Summary
COTI is revolutionizing how privacy functions in Web3 by transforming it from a barrier into a tool of empowerment. Through its high-performance Garbled Circuits technology and programmable privacy framework, COTI offers scalable, fast, and compliant privacy for builders. It’s setting the new standard for decentralized applications, empowering communities and creators with trust, security, and control.
