Zcash, the privacy-focused cryptocurrency built on zero-knowledge proof technology, is preparing to introduce quantum-recoverable wallets within weeks and expects to complete a full post-quantum transition over the next 12 to 18 months, Zcash Open Development Lab CEO Josh Swihart said at a Consensus Miami audience this week. Swihart also pointed to efforts to scale the network toward payment volumes comparable to Visa and Mastercard.
Swihart criticized Bitcoin as no longer meeting the standards of private peer-to-peer money envisioned by early cypherpunks. He argued that transparent blockchain balances expose users to monitoring and increase the risk of asset seizure.
The remarks came as ZEC rallied sharply. The token has risen more than 75% over the past 30 days, supported by fresh backing from Multicoin Capital and a renewed wave of attention around privacy-focused crypto narratives.
At press time, ZEC changed hands at $580, up 3.5% in the last 24 hours, according to CoinGecko.
The basic threat of quantum computing to crypto is that sufficiently powerful quantum computers could, in theory, crack the elliptic curve cryptography that secures virtually every blockchain.
Swihart highlighted a more dangerous variant often described as a “harvest now, decrypt later” strategy, in which adversaries record encrypted data today with the expectation of decrypting it once quantum hardware matures. For a privacy coin, where the value proposition depends on keeping transaction data secret, that risk is described as existential.
Zcash is advancing a multi-phase quantum-resistance strategy, including Project Tachyon, aimed at defending against future decryption risks. The plan also includes strengthening FROST and Zebra infrastructure, with analysts noting that Zcash’s network design may provide an early advantage in adapting to quantum-era security challenges.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
