Horizen (ZEN) stands out in the crowded field of privacy-focused cryptocurrencies. While many digital assets claim to offer anonymity and secure transactions, Horizen goes beyond simple coin transfers by building a full ecosystem centered around data privacy, decentralized infrastructure, and enterprise-grade applications. This review dives into what makes ZEN unique — from its blockchain architecture and node system to its real-world tools like ZenChat, ZenPub, and upcoming sidechain solutions.
What Is Horizen?
Horizen is a privacy-centric blockchain platform that originated as a fork of ZClassic, which itself was derived from Zcash. As such, it inherits the powerful zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge) cryptography that enables fully private transactions. This technology allows users to verify transactions without revealing sender, receiver, or amount — a gold standard in blockchain privacy.
But Horizen isn’t just another privacy coin. It’s an evolving ecosystem designed for both individuals and enterprises seeking enhanced digital confidentiality. The project rebranded from ZenCash to Horizen in 2018, marking a strategic shift toward becoming more than a cryptocurrency — it aims to be a comprehensive privacy platform.
Core components of the Horizen network include:
- ZEN cryptocurrency: The native token used across the ecosystem.
- Sphere by Horizen: A unified app suite for managing privacy tools and finances.
- ZenNodes: A multi-tiered node network enhancing decentralization.
- Sidechains: Scalable blockchain extensions supporting custom dApps.
- ZenDAO: A decentralized governance model for funding future development.
- ZenPub, ZenChat, ZenHide: Privacy-focused applications for publishing, messaging, and censorship resistance.

Why Privacy Matters in the Digital Age
In today’s hyper-connected world, personal data is constantly at risk. Cybersecurity threats aren't limited to individual hackers targeting laptops — they often involve large-scale breaches affecting millions. According to Norton, around 60 million Americans have been impacted by identity theft, and the U.S. accounts for nearly half of all global data breaches.
Enterprises, governments, and major tech firms are prime targets. Even with robust security measures, breaches occur frequently due to vulnerabilities in centralized systems. This is where decentralized privacy solutions like Horizen come into play.
Horizen addresses this growing need by offering tools that empower users to control their own data. Whether it's through anonymous publishing with ZenPub, encrypted messaging via ZenChat, or domain fronting with ZenHide, the platform provides practical applications for real-world privacy challenges.
ZEN Cryptocurrency: Design and Distribution
ZEN was launched on May 23, 2017, via a 1:1 fork of the ZClassic (ZCL) blockchain — meaning every ZCL holder received an equivalent amount of ZEN. There was no ICO or pre-mine, promoting fair distribution from the start.
The total supply is capped at 21 million ZEN, mirroring Bitcoin’s scarcity model. Blocks are mined every 2.5 minutes using the Equihash algorithm, a memory-hard Proof-of-Work consensus mechanism resistant to ASIC dominance (though some ASICs do exist).
Block rewards are distributed as follows:
- 70% to miners
- 20% split between Secure Nodes and Super Nodes
- 10% to the Horizen Team Treasury
This incentivizes not only mining but also node operation, fostering a highly decentralized network. To run a Secure Node, users must stake 42 ZEN, while Super Nodes require higher technical specs and contribute more significantly to network stability.
All node communications are protected using TLS encryption, and transaction data is secured via HTTPS and content delivery networks (CDNs). Combined with zk-SNARKs, this creates a robust layer of anonymity and pseudonymity for all users.
Addressing Security Concerns
One common criticism involves the trusted setup phase required for zk-SNARKs. If compromised during this initial key generation, an attacker could theoretically mint unlimited coins. However, Horizen employs a multi-party computation process involving global participants to minimize this risk.
There have also been unverified rumors about potential backdoors in Zcash’s original codebase being carried over to Horizen. No evidence supports these claims, and ongoing audits and open-source transparency help maintain trust in the system.
Key Products and Use Cases
Horizen differentiates itself through its suite of privacy-enhancing tools:
ZenChat
An end-to-end encrypted messaging app using AES-256 encryption. Unlike traditional platforms, ZenChat leverages blockchain infrastructure to resist surveillance and censorship.
ZenPub
Allows journalists and publishers to share documents anonymously on IPFS (InterPlanetary File System), ensuring content remains accessible even under oppressive regimes.
ZenHide
Uses domain fronting techniques similar to Tor to bypass internet censorship. By masking communication endpoints via HTTPS, it helps users access blocked services securely.
Sphere by Horizen
A mobile and desktop application that integrates wallet functions, node management, and access to all Horizen services in one place — ideal for both beginners and advanced users.
Sidechains
Currently in development, Horizen’s sidechain solution will enable developers to launch custom blockchains interoperable with the mainchain. This opens doors for enterprise adoption, private ledgers, and scalable dApp deployment.

The Team Behind Horizen
Led by co-founder Rob Viglione, a former physicist and mathematician with deep roots in blockchain innovation, Horizen benefits from strong technical leadership. Viglione holds an MBA in Finance & Marketing and is currently pursuing a PhD in Cryptofinance.
Other key figures include:
- Rolf Verslius – Executive Advisor with experience at Cisco and the U.S. Navy Submarine Force.
- Rowan Stone – Business Development Director with over 15 years in tech and energy sectors.
Together, they’ve cultivated a dedicated community across social platforms including Twitter (46K+ followers), Reddit (~3K members), and YouTube (8K+ subscribers), where regular educational content keeps users informed.
Market Performance and Storage Options
ZEN reached an all-time high of **$67.29** in January 2018 during the crypto bull run and dipped to $3.09 in July 2017 shortly after launch. As of recent trends, it has shown resilience and steady recovery.
It ranks among the top privacy coins by market cap and trades on major exchanges like Binance, Huobi Global, and Bittrex. While liquidity is concentrated on Binance, traders should note wider bid-ask spreads compared to larger-cap assets.
For secure storage:
- Use the official Sphere Wallet
- Hardware options include Ledger Nano S/X and Trezor Model T
- Avoid long-term storage on exchanges
Development Activity and Roadmap
Horizen maintains active development across multiple GitHub repositories, with consistent code commits indicating ongoing progress. Node growth has been impressive — a 49% increase in Super and Secure Nodes in 2019 alone.
Although the public roadmap hasn’t been updated recently, key milestones expected include:
- Zen 3.0 core upgrade
- Treasury Sidechain launch
- Sidechain SDK release
- Full ZenDAO implementation
These updates are crucial for expanding developer access and enabling broader enterprise integration.
