Horizen Privacy Mainnet Officially Launches on Caldera, Bringing Privacy Protection to the "On-Chain Network" Ecosystem

Caldera announced that the Horizen privacy mainnet is now officially live and operational within its ecosystem. This launch introduces privacy-preserving technology into Caldera's "Internet of Chains" ecosystem, establishing privacy as a core component and unlocking new categories of application scenarios for cross-chain applications, enterprise adoption, and AI-driven systems.

A Breakthrough in Solving Web3's Privacy Challenge

While traditional public chains achieve data verifiability, they lack privacy protection, leaving user behavior, business logic, and transaction intent completely transparent. This structural barrier severely hinders the development of consumer-grade applications, enterprise adoption, and AI systems. The Horizen mainnet addresses this by providing an end-to-end configurable privacy infrastructure.

Integrating zero-knowledge proof technology, selective disclosure mechanisms, compliance-aware architecture, and full EVM compatibility, the Horizen mainnet transforms privacy from an add-on feature into a programmable characteristic of the chain itself. Developers can build applications using standard tools while gaining advanced privacy protection.

Becoming the Privacy Service Chain in the "Internet of Chains"

The Horizen mainnet joins the network of specialized Rollups built on Caldera's Metalayer, but it contributes unique value: serving as a shared privacy capability for the entire ecosystem. This unlocks various cross-chain possibilities, including cross-chain confidential DeFi, private identity and reputation systems for each application chain, and privacy for AI-powered applications.

Thanks to Metalayer's interoperability, Horizen is not just a destination chain but a service chain. Any other Caldera Rollup can integrate Horizen as a privacy module for its applications, pioneering a new category of "Privacy-as-a-Service" (PaaS) for Rollups.

Metalayer Amplifies Horizen's Impact

One reason Horizen chose Caldera was to ensure its privacy tech stack would not be siloed. With the mainnet launch, the ZEN token achieves universal accessibility through Metatoken and Metalayer, enabling authentication, proofs, and confidential data flows to move cross-chain. Developers on any Caldera chain can instantly deploy privacy components by calling Horizen.

This accelerates the ecosystem flywheel: new chains launch → integrate Horizen privacy features → users and liquidity flow across networks → more developers build → more chains join → Horizen evolves into a privacy hub.

Mainnet Now Open for Use

With the mainnet live, developers can begin deploying privacy-preserving applications that were impossible on transparent chains. Users can access these applications using standard Ethereum wallets like MetaMask. Developers and users can visit https://horizen.hub.caldera.xyz to get started.

The Beginning of the Privacy Era for the "Internet of Chains"

This launch marks a key expansion of Caldera's vision: a world where specialized chains form a unified, interoperable network, with privacy as a core building block rather than an optional add-on. With the Horizen mainnet now live and its privacy infrastructure interoperable, the Caldera ecosystem becomes more powerful, capable, and composable.

Caldera congratulates the Horizen team on reaching this milestone and is proud to partner with them in building the next generation of confidential, interconnected blockchain systems.
