Zcash developers have released Udon, a component that moves portions of the proposed Tachyon scaling upgrade into Zakura Common, the cryptographic library that creates and verifies private transactions. Earlier improvements to Common reduced the time required to generate a private transaction from over three seconds to under 200 milliseconds in certain tests. Udon incorporates calculations needed for Tachyon into Common, where developers can build on previously accelerated code. The upgrade has not been activated on the Zcash network. Project Tachyon leader Sean Bowe and Valar Group developer Dev Ojha stated that the long‑term goal is to process more than 50,000 payments per second, a volume that would require each node to handle over 500 megabytes of data per second under current cryptographic methods. Tachyon aims to combine proofs from multiple payments so that nodes must verify fewer individual proofs, thereby reducing workload. Creating combined proofs requires more memory, prompting the team to develop them using faster Common code. As of the latest data, the network processed roughly 11,700 shielded transactions per day in the week ending September 21, a figure that declined to about 6,200 per day by September 28. The integration of Udon marks the initial step toward a larger scaling plan, though further development and security review remain necessary before any activation.
