Zcash (ZEC)

Zcash (ZEC) is a digital money cryptocurrency launched in 2016 with a maximum supply of 21,000,000 coins. It functions as a privacy-focused alternative to public blockchains like Bitcoin. While standard cryptocurrencies record transaction details openly, Zcash utilizes a specialized technology called zero-knowledge proofs. This mathematical tool allows users to verify that a payment is valid and secure without revealing the sender, receiver, or transaction amount. The network operates on a proof-of-work consensus mechanism, where miners solve complex mathematical puzzles to secure the ledger and earn rewards in ZEC. This system maintains a shared public record of all transactions while offering optional anonymity for specific entries. By combining transparency with selective invisibility, Zcash provides a unique option for individuals seeking financial privacy over the internet. It remains a significant project in the history of decentralized finance, demonstrating how cryptographic innovation can protect user data while preserving network integrity.
