Zcash's Visa-Scale Privacy Solution: 50,000 TPS Target and Ironwood Update

Zcash's team is developing a solution to match Visa and Mastercard's transaction volume, aiming for 50,000 transactions per second with full verifiability and strong privacy guarantees. To achieve this, they will optimize Zcash's existing cryptography and reduce transaction load significantly using Project Tachyon's recursive proofs.

■Tachyon enables a single proof to validate thousands of transactions.

■Current systems handle 500 MB/s, but Tachyon aims to increase this to 500 MB/s with careful engineering.

■Wallets currently process only one transaction per second due to the need to verify each private transaction. Valar Group is working on private information retrieval techniques to overcome this bottleneck.

■The upcoming Ironwood update (NU6.3) is designed to seal the soundness flaw in Orchard's shielded pool.

■Ironwood traps suspicious ZEC amounts at the pool boundary, preventing them from entering circulation.

■The update will activate on July 28 with full support from major organizations. CEX trading volumes rose for the first time in five months in June, with spot volumes climbing 15.3% to $1.11T and RWA perpetual volumes surging to a record $311B.

Zcash's Visa-scale privacy solution represents a significant leap in performance and security for the crypto space. The success of Ironwood could position Zcash as a leading global payments platform. However, wallet and node software optimizations remain incomplete, which could still pose challenges for handling massive transaction volumes.
