Zcash developers are targeting Nov. 5 to switch on NU7, the network's next major upgrade. The biggest improvement is set to be block time, the gap between each confirmed batch of transactions, drops from 75 seconds to 25. That's a three-times speedup for a coin built around zero-knowledge proofs—math that lets someone prove a payment is valid without revealing who sent it, to whom, or how much. Shorter blocks mean shielded, private transactions confirm almost as fast as a card swipe. Myriad: How...

It was a quiet crypto trading session in a quiet summer, but the charts are painting different pictures for Bitcoin, the market leader, and Zcash, one of the hottest altcoins of the last year.

For many years, Bitcoin was used to buy drugs online because it was believed to be anonymous. Turns out, it’s surprisingly easy to track Bitcoin transactions. Zcash, on the other hand, is a cryptocurrency that promised something Bitcoin couldn’t deliver: privacy.

By using cryptographic techniques, transfers can be made that can’t easily be traced on a public ledger while remaining verifi...
