Privacy coin Zcash, in the midst of a volatile year that saw prices spike near all-time highs, is making advances in insulating itself from being cracked by quantum computing. Research published by CoinDesk, which the firm says was commissioned by a group called GenZcash, says that Zcash has roadmaps for both scaling its chain and making it resistant to quantum computing designed to break confidentiality. "We can have the best of both worlds, a private digital payment network that scales to billions of users by fully leveraging both zero-knowledge and verifiable computation" says Sean Bowe, head of Project Tachyon, which is focused on scaling the Zcash blockchain. Zcash is trading up 3.7% to $414, according to data from LSEG. (kirk.maltais@wsj.com)
