ZenCash

ZenCash, operating under the alias ZenCash and headquartered in the United States of America, is a blockchain‑based project that provides a privacy‑focused cryptocurrency and a platform for decentralized applications. The core product is a public blockchain that enables users to send and receive ZEN, the native token, with enhanced confidentiality through the use of zk‑SNARKs zero‑knowledge proof technology. In addition to simple value transfer, the network supports the creation of sidechains and smart contract‑like functionality, allowing developers to build applications that require both privacy and scalability. The blockchain secures its transactions through an Equihash‑based proof‑of‑work consensus mechanism, which was selected for its memory‑hard properties intended to broaden participation in mining. ZenCash’s software is released as open‑source code, and the project relies on a global community of contributors to maintain and upgrade the protocol.

The project distinguishes itself by emphasizing privacy as a foundational feature, employing zero‑knowledge proofs to shield transaction details while still allowing verification on a public ledger. Its use of the Equihash algorithm aimed to reduce the advantage of specialized mining hardware, promoting a more decentralized miner base compared to some competing chains. Following the 51% attack on June 2 2018, which reorganized 38 blocks and resulted in double‑spend losses of approximately $550,000 worth of ZEN, the developers responded by raising the required confirmation threshold to 100 blocks and working closely with exchanges to monitor and mitigate further risks. This incident highlighted the project’s focus on rapid incident response and collaboration with ecosystem partners to strengthen network security. ZenCash’s approach combines privacy‑enhancing cryptography with a community‑driven governance model, positioning it within the broader blockchain sector as a project that seeks to balance confidentiality, security, and developer utility.
