The Oasis Network is a Layer 1, proof-of-stake, decentralized network designed to support the next generation of blockchain applications. It is incredibly versatile, agile, and customizable. Moreover, it supports confidential smart contracts, enabling sensitive data to be used by Dapps and unlocking new use cases and applications of blockchain technology.

Billions Network is a digital identity verification platform designed to offer a future where humans and AI can trust each other, including Sam Altman’s crypto project, World. The platform, which utilizes zero-knowledge proof tech, seeks to provide a scalable and secure method for verifying both human and AI identities.

Octra is an FHE blockchain network with support for isolated execution environments. The majority of the codebase is developed in languages such as OCaml, AST, ReasonML (the language for smart contracts and applications for interacting with the Octra blockchain network), and C++.

Anoma is an intent-centric architecture, introducing a new paradigm for building infrastructure layers and a new operating system for decentralized applications. Anoma’s intent-centricity introduces novel primitives that allow existing web2.5 dApps to be fully decentralized, such as optimistic and ZK rollups, DEXs, NFT marketplaces, or public goods funding applications like Gitcoin.

Fhenix is the confidential blockchain powered by fully homomorphic encryption. Through the usage of fhEVM, Fhenix enables Ethereum developers to seamlessly build encrypted smart contracts and perform encrypted computation of data, all while using Solidity and other familiar, easy-to-use tools.

Aleo is a developer platform for building fully private, scalable, and cost-effective applications. It uses zero-knowledge cryptography to move smart contract execution off-chain, enabling a diverse range of decentralized applications that are both entirely private and can scale up to thousands of transactions per second.

Maroo is a compliant, open, and sovereign Layer 1 blockchain designed specifically for the Korean Won economy. All gas fees on Maroo are paid in OKRW, a stablecoin pegged to the Korean Won. Maroo enforces compliance logic at the transaction level, allowing users to control the information disclosed in each transaction (counterparties, amounts, asset types).

Privacy Cash is a privacy protocol based on Solana that allows users to deposit SOL into a privacy pool and withdraw from the privacy pool to any recipient address.

RadR is a privacy-first infrastructure protocol designed to bring zero-knowledge (ZK) level privacy to Solana payments, transfers, and DeFi interactions, allowing on-chain fund flows to hide amounts, senders, receivers, and transaction patterns by default, achieving true "cryptocurrency privacy."

Brave is a privacy-focused internet browser that aims to change the digital advertising relationship between customers and advertisers. BAT is the native token of the platform, which is used as a payment mechanism between advertisers, publishers, and users.

RAILGUN is a privacy system built directly, enabling users to interact directly with DEXs and other DeFi applications. Individuals can engage in cryptocurrency and DeFi-based activities, ensuring financial freedom without worrying about being spied on by anyone.

Nym is a privacy platform that provides strong network-level privacy against sophisticated end-to-end attackers, and anonymous access control using blinded, re-randomizable, decentralized credentials. It protects privacy at the network layer by encrypting and relaying users' internet traffic through a multi-layered network called a mixnet. In each layer of the mixnet, mix nodes mix users' internet traffic with that of other users, making communications private and hiding metadata such as IP address, who they are talking to, when and where, and more.

zkCLOB is a anonymous, on-chain order book exchange that blends centralized-level performance with the privacy and transparency of decentralized technology. Every trade, order, and interaction is powered by zero-knowledge proofs and settled securely on-chain without exposing user addresses or trading behavior.
