Zcash is a privacy-focused cryptocurrency that uses zero-knowledge proofs to enable shielded transactions. Unlike many transparent crypto transfers, Zcash offers optional private addresses and transaction values, allowing users to shield sensitive details from the public blockchain while still maintaining a verifiable, decentralized network. This privacy layer is implemented via zk-SNARKs, which allow the network to prove that a transaction is valid without revealing sender, recipient, or amount unless the user chooses to disclose it.

How many Zcash coins are there and what is the supply outlook?

Zcash has a maximum supply of 21,000,000 ZEC. As of now, the circulating supply is approximately 16,508,289 ZEC. The supply schedule is designed to converge toward the max supply over time, with new ZEC minted as block rewards. Investors should note that the shortage or abundance of supply can influence price dynamics, but the cap helps create scarcity over the long term.

Where can I buy or trade Zcash, and which wallets support it?

Zcash is listed on many major cryptocurrency exchanges, offering spot trading and sometimes staking-like participation via holders. To acquire ZEC, you can sign up at a supported exchange, verify your identity, deposit funds, and place a buy order. For storage, you can use compatible wallets that support ZEC, including software wallets (desktop/mobile) and hardware wallets. If you want privacy-focused use, consider wallets that support Shielded addresses. Always enable best security practices, such as using hardware wallets for large holdings and keeping seed phrases offline.

What are shielded versus transparent addresses, and how do I use them in Zcash?

Zcash supports two address types: transparent (similar to Bitcoin) and shielded (private). Transparent addresses behave like standard public addresses, with transparent transaction data. Shielded addresses use zk-SNARKs to hide sender, recipient, and amounts. You can convert funds between address types using shielded transactions, but note that shielded transactions can be slower and more resource-intensive. Users typically move some funds to shielded addresses for privacy, while keeping a portion in transparent addresses for liquidity and ease of exchange.

Is Zcash secure and how is privacy protected in practice?

Zcash security hinges on its mature protocol and the use of zk-SNARK proofs to validate transactions without exposing private data. Privacy is optional and can be applied to specific transactions by users. The network relies on a robust proof-of-work consensus and periodic updates to improve privacy features and performance. To maximize privacy, users should opt for shielded addresses and verify that the wallets and services they use support the privacy options offered by Zcash.
