Summary
Zcash developers have introduced Udon, a new software component that integrates parts of their proposed Tachyon scaling upgrade into Zakura Common, which is used to create and verify private transactions on the network. This move aims to improve the network’s ability to handle more private transactions by building on previously faster cryptography code. While Udon has been released, Tachyon itself remains under development and requires further testing before potential activation.
Why it matters
The source indicates that this development prepares Zcash’s network for a significant increase in private transactions by reducing computational workload. Tachyon aims to improve scalability by allowing multiple transactions to share a single cryptographic proof, thus lessening the data each node must verify. However, the impact on actual network speed or capacity is not yet demonstrated.
Key context
Zcash uses complex cryptography to verify private payments without revealing transaction details. Previous improvements to Zakura Common reduced transaction proof creation from over three seconds to under 200 milliseconds in some cases. Tachyon is designed to further advance scalability by combining proofs to reduce nodes' overhead, targeting a future where Zcash could process over 50,000 private payments per second—a scale far beyond current levels.
Key numbers and entities
Zcash, Project Tachyon, Udon, Zakura Common, Sean Bowe (Project Tachyon leader), Dev Ojha (Valar Group), ZecStats data (network transaction statistics). Current network data shows approximately 6,200–11,700 shielded transactions per day as of late September 2026, far below the 50,000 payments per second target.
What remains unclear
The exact improvements Udon brings to Tachyon’s speed and scalability remain unproven in practice. The timing and conditions for Tachyon’s full activation and security approval are not specified. How the additional memory requirements for combined proofs will affect overall system performance is also not detailed.
