Horizen's privacy mainnet officially launched on Caldera, bringing privacy protection to the "on-chain network" ecosystem.

Caldera announced the official launch of the Horizen privacy mainnet within its ecosystem. This launch introduces privacy-preserving technology into Caldera's "Internet of Chains" ecosystem, making privacy a core component of the ecosystem and opening up entirely new application scenarios for cross-chain applications, enterprise adoption, and AI-driven systems.

Breakthrough progress in solving Web3 privacy challenges

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

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

Become a privacy service chain in the "on-chain network"

The Horizen mainnet joins a specialized Rollup network built on Caldera Metalayer, but contributes unique value: shared privacy capabilities across the entire ecosystem. This unlocks various cross-chain possibilities, including confidential cross-chain DeFi, providing private identity and reputation systems for each application chain, and providing privacy protection for AI-enabled applications.

Thanks to Metalayer's interoperability, Horizen is not only the target chain but also the service chain. Any other Caldera Rollup can integrate Horizen as a privacy module for its application, creating a new category of "Privacy as a Service" (PaaS) for Rollups.

Metalayer amplifies the influence of Horizen

Horizen chose Caldera in part to ensure its privacy technology stack was not isolated. With the mainnet launch, the ZEN token achieves universal accessibility through Metatoken and Metalayer, and authentication, proof, and confidential data streams can flow across chains. Any developer on the Caldera chain can instantly deploy privacy components by invoking Horizen.

This accelerates the ecosystem flywheel effect: new chain launches → integration of Horizen privacy features → user and liquidity flow across the network → more developers build → more chains join → Horizen evolves into a privacy hub.

The mainnet is now open for use.

With the mainnet launch, developers can begin deploying privacy-preserving applications that are not possible on a transparent chain. Users can access these applications using standard Ethereum wallets such as MetaMask. Developers and users can get started at https://horizen.hub.caldera.xyz .

The beginning of the privacy era of "on-chain networks"

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

Caldera congratulated the Horizen team on achieving this milestone and expressed his pride in working with them to build the next generation of confidential, interconnected blockchain systems.
