Zcash is a decentralized cryptocurrency that utilizes zero-knowledge proofs, such as zk-SNARKs and the Halo 2 protocol, to offer users a choice between transparent and shielded transactions. This technology allows for the validation of transactions without revealing sensitive data like sender, receiver, or amount.

To improve network performance, the development team released Zakura Common, an open-source cryptography and protocol library. This update optimizes zero-knowledge proof generation, significantly increasing speeds on both mobile and desktop devices. These technical improvements aim to reduce private transaction times to under 200 milliseconds and serve as a foundation for Project Tachyon, which targets a throughput of 50,000 transactions per second.
