Zcash is a privacy-focused cryptocurrency that pioneered zero-knowledge proofs to let users transact with optional, selective confidentiality.
What is Zcash?
Zcash (ZEC) is a proof-of-work cryptocurrency that offers strong privacy through advanced cryptography. Unlike Monero’s privacy-by-default model, Zcash supports both transparent and shielded transactions, letting users choose when to keep details private — a flexibility designed to balance privacy with compliance needs.
The origins of Zcash
Zcash launched in 2016, developed from academic research into zero-knowledge proofs and supported by the Electric Coin Company and the Zcash Foundation. It was one of the first real-world deployments of zk-SNARKs, a cryptographic breakthrough now used widely across the blockchain industry.
How Zcash works
Zcash uses zk-SNARKs (zero-knowledge succinct non-interactive arguments of knowledge), which let one party prove a transaction is valid without revealing the sender, receiver or amount. “Shielded” transactions hide these details, while “transparent” ones behave like Bitcoin. Selective disclosure lets users reveal details to specific parties when needed.
ZEC supply and tokenomics
Like Bitcoin, Zcash has a capped supply of 21 million ZEC and a halving schedule that reduces issuance over time. New ZEC is created through proof-of-work mining that rewards the people securing the network.
What Zcash is used for
Zcash is used by people who want optional financial privacy with the flexibility of selective disclosure, and its underlying zero-knowledge technology has influenced scaling and privacy designs far beyond Zcash itself.
What moves the ZEC price
ZEC tracks demand for privacy, exchange availability, the halving cycle, technical upgrades to its shielded ecosystem and broad market sentiment.
Risks to understand
Like other privacy coins, Zcash faces regulatory and exchange-listing risk, and adoption of shielded transactions has historically been limited. ZEC is volatile. This is educational content, not financial advice.
Shielded versus transparent use
Zcash offers a choice: transparent transactions that work like Bitcoin, or shielded ones that hide the details using zero-knowledge proofs. Historically, much Zcash activity remained transparent, and the project has worked to make shielded transactions easier and more widely used. Selective disclosure also lets users reveal specific details to auditors or counterparties when required, balancing privacy with compliance.
How zero-knowledge tech spread
Zcash helped bring zk-SNARKs from academic theory into a live cryptocurrency, and the broader family of zero-knowledge proofs has since become one of the most important tools in blockchain — powering privacy features and, especially, the zk-rollups now central to scaling Ethereum. Zcash’s influence on the industry extends well beyond its own market.
Supply, halvings and roadmap
Zcash shares Bitcoin’s 21-million cap and halving schedule, so its issuance slows over time. The project continues to refine its shielded ecosystem, wallet experience and the trade-offs around its initial cryptographic setup, all of which shape adoption of its privacy features.
From trusted setup to Halo
Early Zcash relied on a one-time cryptographic “trusted setup” ceremony, whose security depended on participants destroying secret data. The project has worked to remove that requirement through advances like Halo, which enable zero-knowledge proofs without a trusted setup. This evolution addresses one of the most-cited criticisms of Zcash and reflects the broader maturation of zero-knowledge cryptography.
Governance and development funding
Zcash development is funded in part by a portion of the block reward directed to its ecosystem, supporting the Electric Coin Company, the Zcash Foundation and grants. How this funding is allocated and governed has been the subject of active community debate, since it shapes who builds the protocol and how decisions about its privacy roadmap are made.

Zcash FAQ
What are zk-SNARKs?
A form of zero-knowledge proof that lets someone prove a statement is true — such as a valid transaction — without revealing the underlying details.
Is Zcash always private?
No. Zcash supports both transparent and shielded transactions, so privacy is optional and users can selectively disclose details.
Does Zcash have a supply cap?
Yes. Like Bitcoin, Zcash is capped at 21 million coins with a halving schedule.
How is Zcash different from Monero?
Monero makes privacy mandatory and default; Zcash makes it optional via shielded transactions, with selective-disclosure flexibility.
Is Zcash the same as Bitcoin with privacy?
Not quite. Zcash shares Bitcoin’s supply cap and proof-of-work roots but adds optional shielded transactions using zero-knowledge proofs for confidentiality.
