Zcash - What is it and How Does it Work?

Zcash is a privacy-preserving digital currency launched in October 2016 as a fork of the Bitcoin codebase. It operates on a proof-of-work blockchain, with a fixed supply cap of 21 million and a predictable halving schedule. Zcash uses zk-SNARKs (zero-knowledge succinct non-interactive arguments of knowledge), which allows for the verification of transactions without revealing any details about the sender, receiver, or amount.

How Zcash Works:

1. **Transaction Details Encryption:** When a shielded transaction is made, key details like sender address, receiver address, and transaction amount are fully encrypted on-chain. 2. **ZK-Proof Creation:** The sender (prover) uses their private key to generate a zk-proof (zk-SNARK) that confirms several conditions are met without revealing sensitive data: * The sender has enough funds to cover the transaction. * The funds being spent were legitimately created in prior transactions. * The transaction input values equal the output values, preventing the creation of counterfeit coins. * The sender is authorized to spend the funds (possesses the correct private key). * The funds have not been spent before (using a mechanism called "nullifiers"). 3. **Instant Verification:** Other nodes (verifiers) on the Zcash network instantly verify the zk-SNARK proof using a public verification key. The proof is very small (a few hundred bytes) and takes a few milliseconds to verify, making the verification process highly efficient.

Dual Transaction Types

Notably, privacy is optional in Zcash – users can maintain transparency for compliance or audit needs, or they can opt for complete confidentiality. ZEC uses a dual address system, including transparent addresses (t-addresses) and shielded addresses (z-addresses).

ZCash vs. Monero

Zcash positions itself as a Bitcoin-like currency but with optional encrypted privacy. Zcash uses zk-SNARKs, while Monero uses RingCT signatures and Stealth Addresses to provide privacy.

So Why Did The Market Pick ZCash?

One of the biggest contributors to ZCash’s recent growth is ECC's (Electric Coin Co's) focus on consumers. A large part of this is the development of Zashi, the official ZCash wallet. The launch of Zashi has significantly improved the user experience of Zcash.

The New Significance of Privacy

With governments and regulators heavily pushing for surveillance measures, the cypherpunk ethos is back in focus. Zcash offers a hedge for those concerned about these trends: an encrypted, unmonitorable form of money.

Post-Halving Supply Dynamics

Zcash’s second halving (November 2024) significantly reduced its new coin issuance, and we are now seeing the impact. Circulating supply is tightening while demand is rising, this is a textbook supply-demand squeeze.

Conclusion

Zcash's recent surge signals a renewed interest in privacy within the cryptocurrency space. With its innovative technology, improvements in user experience, and strong supply dynamics, Zcash is poised for continued growth in the future.
