Secret Network

Secret Network is an independent, base-layer blockchain network built using the Cosmos SDK. It supports smart contract development and introduces data privacy by default for these contracts, enabling developers to build decentralized applications that also protect user data and preserve privacy. The protocol implements "programmable privacy," which is defined as arbitrarily complex data privacy controls within an application. Secret Network calls these privacy-preserving applications "Secret Apps." On February 13, 2020, Secret Network's mainnet went live, and its goal is to become the data privacy center of Web3.
