Horizen (ZEN) is a privacy-focused blockchain platform that enables developers and businesses to build custom blockchains and decentralized applications. Its native cryptocurrency, ZEN, powers the ecosystem and offers optional privacy features for transactions. This guide explores Horizen's technology, uses, and market position.
What is Horizen (ZEN)?
Horizen is a comprehensive blockchain ecosystem designed for building both public and private blockchains and decentralized applications (dapps). The platform emphasizes privacy and scalability through its innovative sidechain technology called Zendoo, a verified cross-chain transfer protocol. Horizen incorporates zero-knowledge proof technology (zk-SNARKs) to ensure secure communication between sidechains and the main blockchain.
The native cryptocurrency ZEN offers two address types: T-Addresses for transparent public transactions and Z-Addresses for private shielded transactions. ZEN is distributed as rewards to miners and secure nodes and is available for trading on various cryptocurrency exchanges.
Historical Development of Horizen
Horizen was launched in 2017 under the name ZenCash as a fork of Zclassic, which itself was a fork of Zcash. The project was founded by Robert Viglione (CEO of Horizen Labs) and Rolf Versluis (President of the Zen Blockchain Foundation) with a focus on developing privacy-focused technologies with a sustainable funding model.
The project faced a significant challenge in June 2018 when it experienced a 51% attack, resulting in three double-spend transactions totaling approximately 23,152 ZEN. In response, the development team implemented enhanced security measures including a penalty system for delayed block reporting, making future attacks significantly more difficult and costly.
Following this incident and to avoid confusion with Zcash, the project rebranded to Horizen in August 2018, marking its transition from a simple cryptocurrency to a comprehensive privacy platform with scalability solutions. The project launched without a token sale, pre-mine, or ICO.
How Horizen's Technology Works
The Horizen ecosystem consists of a main blockchain and a sidechain platform that enables developers to create custom blockchain solutions. The network utilizes a hybrid consensus mechanism combining Proof of Work (PoW) for maintaining network consensus and Proof of Stake (PoS) for validation.
Key technological features include:
- Zendoo Protocol: A cross-chain transfer protocol enabling sidechain development
- Zero-Knowledge Proofs: zk-SNARK technology ensuring transaction privacy
- Equihash Algorithm: The PoW algorithm used for mining ZEN
- Dual Address System: Both transparent (T) and shielded (Z) addresses
Block rewards are distributed with 60% allocated to miners, 20% to the treasury, and 20% to node operators. This economic model ensures proper incentivization for all network participants. 👉 Explore advanced blockchain technologies
Practical Applications of ZEN
The ZEN token serves multiple functions within the Horizen ecosystem:
- Network Fuel: Powers transactions and operations on the platform
- Privacy Features: Optional privacy through shielded addresses
- Development Platform: Enables creation of custom blockchains and dapps
- Incentive Mechanism: Rewards for miners, node operators, and contributors
The platform's sidechain capability allows developers to build scalable solutions without the limitations typically associated with mainchain operations. Users can participate in the network by running nodes or contributing computational power, and can even obtain free ZEN through the Horizen Faucet program.
Frequently Asked Questions
What makes Horizen different from other privacy coins?
