Shielded Labs has assembled a three-person cryptography team—Ulrich Haböck as Chief Cryptographer, plus Luke Edwards and Suyash Bagad as engineers—to build production-ready post-quantum cryptography for Zcash. The project targets a formally verified implementation by the end of 2027, providing at least 128 bits of security, and will coordinate with Project Tachyon contributors. Since NU6.3, Ironwood notes are designed to be quantum-recoverable. The team cites the 2018 Sprout and 2026 Orchard vulnerabilities as evidence that design and implementation errors, not just math, pose serious risks.

    We're living in scary times in the crypto and privacy space. But giving up isn't an option. The only way out is through. I've gotten to know the Shielded Labs team pretty well, and their work to future proof Zcash I think will pay dividends to the whole rest of the space. Cool… https://t.co/q9x9jODvG7

    Congrats to Ulrich, Luke, and Suyash (great cryptographers from StarkWare and Aztec) who are joining Shielded Labs to work on post-quantum research for Zcash! They're just the latest in a string of high-caliber folks joining Zcash over the past year. LFG!

    I am proud to welcome Ulrich Haböck, Luke Edwards, and Suyash Bagad to Shielded Labs. The world needs Zcash. And Zcash needs future-proof cryptography. Post-quantum, post-AI, post-everything! Please welcome Ulrich, Luke, and Suyash into the Zcash community. https://t.co/qEZB2vRS5B

    🛡️ Zcash 101: What Epoch actually is Zcash keeps balances and payments private with cryptography. Today that mostly rests on elliptic curves. A large enough quantum computer could, in theory, break those curves and weaken both privacy and the monetary base. ⚛️ Epoch is Shielded… https://t.co/1O5IBpSjxc
