What is COTI (COTI)?

Deep Dive

1. Purpose & Evolution

COTI, which stands for Currency Of The Internet, launched in 2017 with a focus on fast, scalable payments. By 2025, it completed a strategic pivot to become a programmable privacy infrastructure for Ethereum and over 70 other chains (COTI Foundation). Its core mission is to solve the transparency problem of public blockchains, which exposes sensitive data like trading positions and transaction history, a major barrier for institutional adoption. COTI enables confidential transactions where logic, balances, and counterparties remain encrypted, supporting compliance through selective disclosure to regulators.

2. Core Technology: Garbled Circuits

Instead of relying on traditional zero-knowledge proofs (ZK-SNARKs), COTI V2 employs Garbled Circuits (GC), a cryptographic protocol. This technique allows computations to be performed on encrypted data off-chain, making it significantly faster—reportedly up to 3,000 times quicker than some alternatives—while maintaining low costs (CoinMarketCap). Transactions are processed privately in this off-chain environment, with only the final, verifiable result settled on the Ethereum mainnet. This hybrid approach aims to deliver enterprise-grade privacy that is both scalable and compatible with existing Ethereum Virtual Machine (EVM) tools.

3. Ecosystem & Use Cases

COTI’s ecosystem is built around practical applications of its privacy stack. Key components include the Privacy Portal for one-click shielding of assets like wETH and USDC, and PriveX, a private, AI-powered perpetual DEX. The network also supports the creation of private ERC-20 tokens and stablecoins, with COTI serving as the original tech provider for Cardano’s Djed stablecoin. Through its Builders Program and partnerships with coalitions like the Tokenized Asset Coalition (TAC), COTI is fostering development in private real-world asset (RWA) tokenization, confidential DeFi, and cross-chain privacy solutions.

Conclusion

Fundamentally, COTI is a specialized privacy engine for public blockchains, designed to bring institutional-grade confidentiality and compliance to on-chain finance. Will its focus on programmable privacy become the standard infrastructure for tokenizing trillions in real-world assets?
