Zcash (ZEC)

Rank #14

Zcash (ZEC) is a privacy-focused cryptocurrency. It enables fully encrypted transactions using zero-knowledge proofs without requiring trust between the parties, while maintaining security and transparency on the network. The goal is to reduce the data exposure that usually occurs on traditional blockchains.

How privacy works in Zcash

The network uses trustless zero-knowledge proofs to validate transactions without revealing sensitive information. As a result, details such as sender, recipient, or amounts are not exposed. This mechanism was designed for peer-to-peer payments where confidentiality is relevant.

In Zcash, there is a choice between transparent public transactions and shielded private transactions. Through Unified Addresses, it is possible to interact in both modes, while the use of shielded pools (such as Orchard) concentrates encrypted operations.

Network, consensus, and protocol evolution

Currently, Zcash operates on its own blockchain with Proof-of-Work (PoW) consensus. The evolution of the system includes the “Crosslink” upgrade, which is planned to move toward Proof-of-Stake, aiming to improve security, scalability, and energy efficiency.

The protocol has a fixed supply of 21 million ZEC and follows a halving schedule similar to Bitcoin’s. With each block, there is mining at a pace described in the base text, and transaction fees tend to be low, in fractions of a cent.

History, purpose, and utility

Zcash was created by a group of scientists in 2013, following the initial idea of Zerocoin as a privacy extension for Bitcoin. Later, the project evolved into its own protocol focused on private payments.

With zero-knowledge proof cryptography, Zcash is positioned for uses such as everyday payments, long-term savings, and cross-border transfers when financial confidentiality matters.
