View ChartZcash is a decentralized, open-source cryptocurrency built with a strong emphasis on transactional privacy and selective transparency. It utilizes advanced zero-knowledge cryptography called zk-SNARKs to enable fully shielded transactions where sender, receiver, and amount are encrypted. Unlike fully anonymous coins, Zcash offers users the flexibility to choose between transparent (like Bitcoin) and private transactions. The project was founded by a team of renowned scientists and cryptographers, including Zooko Wilcox-O'Hearn. With a fixed total supply of 21 million coins, ZEC employs a Proof-of-Work consensus mechanism using the Equihash algorithm.
Zcash is a privacy-enhancing digital currency that allows users to protect their financial information using cutting-edge cryptographic technology.
| Item | Details |
|---|---|
| Name (Ticker) | Zcash (ZEC) |
| Alternative Names | ZEC |
| Consensus Mechanism | Proof-of-Work (PoW) |
| Category | Privacy Coin |
| Hash Algorithm | Equihash |
| Block Reward | Every 75 seconds a new block is mined and a block reward enters circulation; the reward halves roughly every four years until all 21 million ZEC are in circulation. Crypto.com records the block reward as 3.125 ZEC, while the z.cash economics page records 1.5625 ZEC. |
| Max Supply | 21,000,000 ZEC |
| Block Time | 75 seconds |
| Block Size | 2 MB |
| Default Fee | 0.0001 ZEC |
| Scaling Solution | Layer-2 solutions like Zcash Shielded Assets (ZSA) are in development |
| Blockchain | Native Zcash blockchain, a fork of the Bitcoin codebase |
Zcash was developed by a team of world-class scientists and engineers. The project was initiated by Zooko Wilcox-O'Hearn, a well-known figure in the crypto space with a background in decentralized systems. The core technology, particularly the zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) protocol, was built upon the Zerocash research lineage, whose founding scientists came from Johns Hopkins in partnership with MIT and Tel Aviv University; co-founder Alessandro Chiesa is an assistant professor at the University of California, Berkeley. The Electric Coin Company (ECC) is the primary entity supporting Zcash's development. Zcash was first released on October 28, 2016, with its foundational paper, "Zerocash: Decentralized Anonymous Payments from Bitcoin," available as IACR ePrint 2014/349.
Zcash operates on a blockchain forked from Bitcoin's code, so it shares many foundational elements like a fixed supply and a Proof-of-Work consensus mechanism. Its revolutionary feature lies in its use of zk-SNARKs. This advanced cryptography allows the network to verify that a transaction is valid without revealing any sensitive information about it. Users have two types of addresses:
This dual-address system provides users with control over their financial privacy, though the actual privacy outcome depends on the protocol version, the transaction path, the wallet, and the rest of the user's environment.
Zcash's primary value proposition is its robust and optional privacy. Zcash is the first cryptocurrency to develop zero-knowledge encryption (zk-SNARKs) for private peer-to-peer payments, bringing enterprise-grade cryptography to the public.
ZEC serves as digital cash with a primary focus on private transactions.
The Zcash ecosystem is evolving through protocol upgrades and community governance.
Zcash uses the Equihash algorithm for mining, a PoW mining algorithm based on the generalized birthday problem (birthday paradox).
Securing ZEC, especially shielded funds, requires careful key management.
ZEC is a well-established cryptocurrency available on many major exchanges. Users can complete KYC on a compliant platform and then purchase ZEC.

| Comparison Metric | Zcash (ZEC) | Monero (XMR) | Bitcoin (BTC) |
|---|---|---|---|
| Privacy Mechanism | Zero-Knowledge Proofs (zk-SNARKs) | Ring Signatures, Stealth Addresses, RingCT | Transparent Blockchain (No native privacy) |
| Privacy Mode | Optional Privacy (t-address vs. z-address) | Mandatory Privacy (Default full encryption) | Fully Transparent (Public & traceable) |
| Transaction Traceability | t-addresses are traceable; z-addresses are fully encrypted | On-chain transactions are completely untraceable | On-chain transactions are public and fully traceable |
| Regulatory Compliance | High (Supports opt-in disclosure via Viewing Keys) | Low (Facing exchange delisting risks due to mandatory anonymity) | Very High (Dominant institutional asset in regulated finance) |
