ZK turnover
Prove your turnover,keep your transactions privat
The problem ZK turnover solves
Small businesses often need to prove their turnover but may have to share detailed transaction records. Our app lets them prove that their taxable turnover is below a limit without revealing their individual transactions. This makes financial verification more private and safer.
Challenges I ran into
Handling 10,000 transactions without slowing down the dashboard.
Keeping transaction data completely local during proof generation.
Connecting the proof flow with an Ethereum smart contract.
Getting the ZK setup working within a short hackathon timeframe.
Fixing TypeScript and dependency issues during development.
