Zcash Advances 50,000 TPS Goal With Tachyon Integration
Zcash developers have begun integrating Project Tachyon’s recursive-proof technology into Zakura Common, the cryptography stack powering the new Zakura full node. The work targets a longer-term goal of processing more than 50,000 private payments per second.
The integration marks another step in Zcash’s effort to make shielded payments operate at global payment-network scale. Tachyon remains a proposed upgrade and has not been activated on the Zcash mainnet.
Tachyon Moves Into Core Infrastructure
Project Tachyon said developers are now upstreaming its recursive proofs into Zakura Common. The move will allow Tachyon to use optimized cryptographic components already developed for Zcash’s newer software stack.
Tachyon and Zcash’s Ironwood system share the Pasta elliptic curve cycle. However, Tachyon introduces additional requirements for recursive proofs and vector commitments.
Developers are therefore adjusting Common’s architecture to support both systems more directly. The team has also released new Zakura crates that replace mature components of its earlier Ragu codebase.
The approach could reduce duplicated cryptographic code while allowing Tachyon to benefit from existing performance work.
Building Toward 50,000 Private Payments
Zakura launched in July as a new Zcash full node developed by Project Tachyon and Valar Group. Its developers have described more than 50,000 transactions per second as a baseline for supporting payments at the scale of major card networks.
CoinDesk reported in August that Zakura Common had already produced major performance gains. In some cases, the software reduced private transaction creation from more than three seconds to under 200 milliseconds.
The new stack also improves hashing, wallet synchronization and transaction verification. Developers say these improvements can be adopted by wallets without requiring a Zcash network upgrade.
Tachyon is designed to address deeper scaling constraints through recursive proofs and proof-carrying data. Its architecture aims to reduce transaction sizes and the amount of state validators must maintain.
The latest integration does not itself deliver 50,000 transactions per second. Instead, it strengthens the cryptographic foundation developers are building toward that target.
