Zcash2026-10-01 13:09:25Zcash integrates Udon into Zakura Common as it works toward 50,000 TPS private transactionsZcash developers have integrated Udon, a core component of the Project Tachyon scaling effort, into Zakura Common, a shared cryptographic library already used across the Zcash ecosystem. The move is aimed at supporting a long-term goal of handling more than 50,000 private transactions per second. Udon has been released as software, but the broader Tachyon upgrade is not live on the Zcash mainnet and is still subject to additional development and security review, making a near-term launch unlikely. According to the source report, Udon brings key Tachyon computation logic into Common early, allowing developers to build on code that has already been optimized. Earlier improvements to Common cut single private transaction creation time from more than three seconds to under 200 milliseconds. The report also says Tachyon is designed around aggregated proofs, which would let nodes validate many transactions through a single proof and reduce the amount of data they need to receive and check. That matters because, at 50,000 TPS, each Zcash node would otherwise need to handle more than 500 megabytes of data per second. On-chain figures cited from ZecStats show current private transaction activity remains far below that target, underscoring that Tachyon is being built for long-range capacity rather than short-term demand.40
Zcash2026-09-29 12:15:46Zcash developers fold Tachyon code into existing software as privacy scaling work advancesZcash developers are moving part of the proposed Tachyon scaling upgrade into software already used by the network, according to CoinDesk. The component, called Udon, was originally built as part of Project Tachyon and was released on Monday to Zakura Common, a shared cryptography library used by Zakura and other Zcash projects. Sean Bowe, who leads Project Tachyon, said the release is meant to prepare the system for a future with far more private transactions. Common handles some of the heavy mathematical work behind creating and verifying shielded payments. Zakura is being developed by Bowe’s team together with Dev Ojha’s Valar Group. CoinDesk noted that earlier improvements to Common had already reduced the time needed to create a private transaction from more than 3 seconds to under 200 milliseconds in some tests reported in August. Udon has been released as software, but the upgrade has not yet been activated on Zcash. Bowe and Ojha have set a long-term target of more than 50,000 payments per second. At that rate, they estimate current cryptography would cause each Zcash node to receive more than 500 MB of data every second.240
