## Overview

COTI runs a confidential EVM in production on Ethereum rails, built on garbled circuits developed with Soda Labs technology, with more than 125 million transactions behind it. It is the strongest existing evidence that the approach holds at public-network scale: standard EVM contracts, encrypted state, live applications, and an Enterprise Ethereum Alliance report singling out the design as production-ready privacy at scale. The engine that powers COTI powers Bubble.

## About Garbled-circuit MPC

Several parties jointly evaluate a function over encrypted inputs using garbled circuits and secret sharing, so no single party ever holds the plaintext. Compared side by side with the other approaches at https://www.sodalabs.xyz/taxonomy.
