Caldera announced that Horizen's privacy mainnet is now live within its ecosystem. This release brings privacy protection technology into Caldera's 'Internet of Chains' ecosystem, making privacy a core component of this ecosystem and opening up new categories of applications for cross-chain use cases, enterprise adoption, and AI-driven systems.
A breakthrough in solving Web3 privacy challenges
While traditional public blockchains achieved data verifiability, they lack privacy protection, leaving user behavior, business logic, and transaction intent fully transparent. This structural barrier severely hinders the development of consumer applications, enterprise adoption, and AI systems. Horizen mainnet addresses this issue by providing end-to-end, configurable privacy infrastructure.
Horizen mainnet integrates zero-knowledge proof technology, selective disclosure mechanisms, 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 benefiting from advanced privacy protection.
Becoming a privacy service chain within the 'Internet of Chains'
Horizen mainnet has joined the specialized Rollup networks built on Caldera Metalayer, but it contributes unique value: shared privacy capabilities across the entire ecosystem. This unlocks multiple cross-chain possibilities, including cross-chain confidential DeFi, private identity and reputation systems for each application chain, and privacy protection for AI-powered applications.
Due to Metalayer's interoperability, Horizen is not just a target chain but also 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
Horizen chose Caldera partly to ensure its privacy technology stack wouldn't be isolated. With mainnet launch, ZEN tokens achieve universal accessibility through Metatoken and Metalayer, enabling authentication, proofs, and confidential data flows to move across chains. Any developer on a Caldera chain can instantly deploy privacy components by calling Horizen.
This accelerates the ecosystem flywheel effect: 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 is now live for use
With mainnet launch, developers can now deploy privacy-protected applications that were impossible on transparent chains. Users can access these applications using standard Ethereum wallets like MetaMask. Developers and users can begin using the platform at https://horizen.hub.caldera.xyz.
The beginning of the privacy era for the 'Internet of Chains'
This release 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. Horizen mainnet is now live, its privacy infrastructure is interoperable, and the Caldera ecosystem is now stronger, more capable, and more composable.
Caldera congratulates the Horizen team on achieving this milestone and expresses pride in collaborating with them to build the next generation of confidential, interconnected blockchain systems.
