Zero-Knowledge Proof

The Horizen node system is a layered network structure that extends beyond traditional miner-based consensus by introducing Secure Nodes and Super Nodes.

Horizen (ZEN) and Zcash (ZEC) are blockchain networks built on zero-knowledge proof technology, representing distinct development paths: modular blockchain architecture and privacy coin ecosystems. As privacy technology has emerged as a critical area of blockchain research, the two have taken divergent approaches—Zcash prioritizes transaction privacy and on-chain data protection, whereas Horizen expands privacy technology to cross-chain verification and system architecture, enabling multi-chain scalability and modular design.

Horizen's sidechain architecture is a cross-chain scaling framework built on the Zendoo protocol and zero knowledge proofs. It is designed to enable multiple sidechains to run in parallel with customizable functionality while preserving the security of the mainchain. The core idea is to transform sidechain state into verifiable cryptographic proofs, which are then validated by the mainchain. This allows cross-chain interaction to occur without relying on centralized intermediaries. Within this system, Zendoo serves as the key connection layer between sidechains and the mainchain, enabling verification through cryptographic proofs rather than trust based mechanisms.

Midnight is a privacy-focused blockchain network developed by Input Output Global and serves as an important infrastructure component within the Cardano ecosystem. Through technologies such as zero knowledge proofs, a dual state ledger architecture, and programmable privacy mechanisms, the network enables blockchain applications to protect sensitive data while maintaining verifiability.
