zkVoting is the first public blockchain voting system to utilize zero-knowledge proofs (ZKP) and satisfy the following properties: end-to-end verifiability, privacy, and integrity. Current blockchain voting systems struggle to overcome the technical challenges of utilizing public blockchain and are forced to remain on a private blockchain. Moreover, there have yet to be successful adoptions of ZKP technology in a voting system. zkVoting has successfully developed a voting system that supports secret voting on a public blockchain with ZKP technology. The highly optimized ZKP guarantees legitimate information without revealing voter identification and the ballot's content.

zkVoting poll station is the first in-person blockchain-powered voting system. Recognised with the Best of Innovation award at CES 2024, zkVoting introduces seamless on-site voting support. Voters can now verify the accurate casting of their ballots in real-time at the poll station. Our zero-knowledge proof protocol enables anyone to verify vote validity while upholding voter privacy. We separate the voting and vote validation devices to prevent malware, resolve appliance suspicion, and foster process credibility. zkVoting empowers citizens to confidently engage in both online or in-person voting, ensuring transparency security, and advancing democracy.

Azeroth is the world's first Crypto & NFT Wallet app that supports anonymity and auditing on a public blockchain. Our privacy-preserving solution distinguishes us from present anonymous transaction services in achieving confidentiality and satisfying AML (anti-money laundry regulations). Azeroth utilizes zk-SNARK technology (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge) to validate public and anonymous transactions with privacy. Furthermore, Azeroth is exercised on a mobile application to satisfy user accessibility and convenience. Finally, Azeroth enables consumers to trade a diverse portfolio with security and reliability, being the first Crypto & NFT digital wallet to employ a prevention auditor against malicious activities.

Kroma aims to develop a universal ZK Rollup based on the Optimism Bedrock architecture. Currently, Kroma operates as an Optimistic Rollup with ZK fault proofs, utilizing a zkEVM based on Scroll. The goal of Kroma is to eventually transition to a ZK Rollup once the generation of ZK proofs becomes more cost-efficient and faster.

Tachyon is a Modular ZK Backend, powered by GPU. Tachyon started from scratch to meet all three requirements. The four main goals of the project are the followings: Blazing Fast / General Purpose / GPU Interoperability / Easy to Use
