Zcash ZEC

Zcash (ZEC) is a privacy-focused cryptocurrency launched in 2016 that gives users the option to hide the sender, receiver, and amount of a transaction. It pioneered the practical use of zero-knowledge proofs in a public blockchain, letting people prove a transaction is valid without revealing its details.

How Zcash works

Zcash is a fork of the Bitcoin codebase and shares its proof-of-work foundation and 21 million coin cap. What sets it apart is selective privacy: addresses come in transparent and shielded forms. Transparent transactions look similar to Bitcoin's public ledger, while shielded transactions use a cryptographic technique called zk-SNARKs to validate transfers without exposing the participants or value involved.

This design lets users choose how much information to disclose. They can transact publicly, move funds into a shielded pool, or share viewing keys with auditors and counterparties when transparency is required. The protocol has gone through several upgrades aimed at reducing the cost of shielded transactions and removing the original trusted setup.

What Zcash is used for

• Confidential payments: shielded transfers keep balances and amounts private by default.
• Selective disclosure: viewing keys allow compliance, auditing, or proof of payment when needed.
• Store of value: like Bitcoin, ZEC has a capped supply and disinflationary issuance.
• Research base: its zero-knowledge work has influenced privacy tooling across the wider industry.

Tokenomics & supply

Zcash caps its total supply at 21 million ZEC, mirroring Bitcoin, with new coins issued through mining rewards that decrease over time via halving events. A portion of early block rewards funded ongoing development and the supporting organizations behind the project, a structure that has evolved over the network's life.

Risks and considerations

Privacy coins face heightened regulatory scrutiny, and some exchanges have delisted or restricted them in certain jurisdictions, which can affect liquidity and access. Shielded transactions have historically seen lower adoption than transparent ones, and the cryptography, while well studied, is complex. As with any crypto asset, ZEC is volatile and prospective holders should weigh custody, regulation, and their own risk tolerance.
