COTI

# COTI > COTI is the programmable privacy layer for Web3, built for enterprises, builders, and agents. Powered by Garbled Circuits and the COTI Nightfall ZK rollup, COTI enables encrypted, compliant computation across DeFi, AI, and other on-chain applications. COTI's V2 architecture is built on Garbled Circuits (GC), a cryptographic technique for computing over encrypted data that is designed to be lighter and faster than alternatives such as Fully Homomorphic Encryption (FHE) and approaches based solely on Zero-Knowledge proofs (ZK). This enables private smart contracts, confidential ERC20/ERC721 tokens, and compliant on-chain data while preserving full EVM programmability. Key facts: - Native token: COTI, used for gas, staking, and node rewards. - Core innovation: Garbled Circuits enable computation on encrypted data, so sensitive inputs stay private throughout execution. - Privacy Portal: COTI V2's dApp for converting supported ERC20 tokens into private tokens, holding encrypted balances, and sending confidential transfers, with decryption handled locally via the COTI MetaMask Snap. - Privacy-on-Demand (PoD): a framework and SDK for integrating confidentiality into dApps, including on other chains. PoD developer tutorials currently run on the Ethereum Sepolia testnet. - Node Ecosystem: community-run Full Node licenses and treasury pools secure the network and process private computations, earning staking rewards. - Ecosystem: privacy-preserving DeFi (PriveX perp-DEX), real-world assets (RWAs), confidential payments, and AI-agent applications with private agent-to-agent messaging.
