Hyperledger's new lab, Zeto, has launched an open-source privacy solution designed to address the privacy concerns of enterprises on the Ethereum blockchain. Developed by Kaleido, Zeto uses zero-knowledge proof (ZKP) technology to provide multiple layers of privacy protection for Ethereum by introducing a Bitcoin-like token design. This includes privacy features ranging from anonymous senders and receivers to hiding transaction amounts and history. The appearance of Zeto responds to institutional interest in licensed versions of Ethereum, particularly in projects such as DREX, the Brazilian Central Bank's digital currency (CBDC) project, where privacy concerns have caused delays. Zeto's unique design is similar to Bitcoin's UTXO model and differs from Ethereum's traditional ERC-20 token standard, providing greater privacy protection for enterprise users.
