Zcash: The Privacy-Focused Cryptocurrency
Launched in 2016 as the first mainstream cryptocurrency built on zero-knowledge proofs, Zcash offers shielded transactions that hide sender, receiver, and amount. After years of regulatory pressure and exchange delistings pushed it from the spotlight, the first US spot privacy-coin ETF and a return to four-figure prices in 2026 brought the privacy sector back into institutional view.
Timeline
Zcash Launches as the First Mainstream Zero-Knowledge Cryptocurrency
Zcash launched on October 28, 2016 as a fork of Bitcoin's codebase replacing its transparency with zk-SNARK-based shielded transactions. Launch participants ran a multi-party ceremony to generate the cryptographic parameters, the process later nicknamed destroying "toxic waste," and 20 percent of block rewards initially went to founders and backers under the Founders' Reward. ZEC joined Bitcoin in the rare class of coins with a fixed 21 million supply cap.

Sapling Upgrade Makes Shielded Transactions Practical
The Sapling network upgrade activated on the second anniversary of the genesis block and cut the cost of building shielded transactions by orders of magnitude, taking construction time from minutes to seconds and making shielded mobile wallets feasible. Before Sapling, most transactions ran transparent; afterward, shielded use grew steadily and the upgrade became the technical foundation for later privacy pools.

Canopy Ends the Founders' Reward
The Canopy upgrade activated in November 2020 and permanently retired the Founders' Reward, redirecting 20 percent of block rewards into a development fund split between the Electric Coin Company, the Zcash Foundation, and community grants. Canopy also deprecated the original Sprout shielded pool to push users onto the more efficient Sapling pool, closing out the last vestige of Zcash's investor-funded launch structure.

NU5 Brings Halo 2 and Removes the Trusted Setup
The NU5 upgrade activated the Orchard shielded pool and introduced Halo 2, a recursive proof system that removed the need for new trusted-setup ceremonies and their "toxic waste" risk. NU5 also shipped unified addresses that let a single address receive both transparent and shielded transfers, a usability milestone for private payments on the network.

Grayscale Lists the First US Spot Privacy-Coin ETF on NYSE Arca
Grayscale converted its nine-year-old Zcash Trust into ZCSH, the first US-listed spot exchange-traded fund holding a privacy coin, which began trading on NYSE Arca with roughly 304 million USD in assets. The listing opened regulated ZEC exposure to brokerage accounts for the first time and came as ZEC rallied to its strongest prices since early 2018.

ZEC Tops 1,000 USD for the First Time Since 2016
Zcash crossed 1,000 USD for the first time in nearly a decade on September 4, 2026, touching an intraday high of 1,021.58 USD and lifting its market capitalization to roughly 17 billion USD. A short squeeze burned an estimated 34 million USD in bearish positions while ETF inflows and rising mining hash rate fed the rally, reviving the privacy-coin sector alongside tokens like Dash.
