Zcash has released Zakura, a new full node software designed to scale its privacy-focused blockchain to handle transaction speeds comparable to Visa and Mastercard, targeting over 50,000 transactions per second. Zakura is a pruned, fast-syncing fork of Zebra that supports the upcoming Ironwood upgrade to secure the network against counterfeit coins. The project addresses major bottlenecks in data verification and wallet privacy through innovations like recursive proofs (Project Tachyon) and private information retrieval techniques by Valar Group. The Ironwood upgrade activates on July 28, marking a critical step in improving Zcash's scalability and security for high-volume private payments.
