Horizen (ZEN): Why This Blockchain Is Taking a Different Approach

When people hear “Horizen,” privacy is probably one of the first things that comes to mind. That makes sense. Privacy has been a central part of the project's identity for years. But Horizen has changed quite a bit, and its current architecture looks very different from the network many people may remember. Today, Horizen is an EVM-compatible Layer 3 built on Base using the OP Stack. That shift makes it interesting not only as a crypto project, but also from a developer's perspective. From a standalone blockchain to an Ethereum-based L3 Horizen originally developed its own blockchain infrastructure around a mainchain and sidechains, with a strong focus on privacy and scalability. The project later moved toward an EVM-based ecosystem and eventually migrated ZEN to Base. The current Horizen Chain is an L3 that settles on Base, which itself is an Ethereum Layer 2. The idea is fairly straightforward: instead of building every part of the infrastructure from scratch, Horizen can use an existing Ethereum-compatible stack while focusing on features specific to its own ecosystem. For developers, that means a much more familiar environment. The EVM part is important One of the biggest practical advantages is compatibility with the Ethereum Virtual Machine. Horizen uses a near-standard EVM, so developers can work with familiar tools, smart contracts and development frameworks. That matters more than it might sound. A new blockchain can have interesting technology, but if developers have to learn an entirely new programming model and tooling ecosystem, adoption becomes much harder. With an EVM-compatible environment, developers who already know Ethereum or Base can transfer much of that knowledge to Horizen. So where does privacy come in? This is probably the most interesting part. Horizen hasn't simply abandoned its original focus on privacy. Instead, privacy is being approached more as an application-level capability. The goal is to make it possible to build applications where transactions or computations can remain verifiable without necessarily exposing every piece of underlying information. That can be useful for areas such as: financial applications identity payments compliance confidential data DeFi This is becoming a bigger issue across the blockchain industry. Public blockchains are excellent at transparency and verification, but complete transparency isn't always desirable. A financial application, for example, may need to prove that a transaction follows certain rules without making every piece of sensitive information publicly available. That's where privacy technologies and zero-knowledge proofs become particularly interesting. What about ZEN? ZEN is the native token associated with the Horizen ecosystem. Its infrastructure has changed alongside the network. Following the migration, ZEN is represented as an ERC-20 token on Base, rather than operating as the native asset of the old Horizen mainchain. That change is significant because it places ZEN inside a much broader Ethereum-compatible environment. It also makes the distinction between the token and the underlying network more important. ZEN is the asset, while Horizen is the infrastructure being built around it. Why the L3 model is interesting The L3 approach isn't simply about adding another layer to the blockchain stack. It allows Horizen to specialize. Base provides the underlying settlement environment, while Horizen can focus on its own execution environment and privacy-oriented functionality. The OP Stack also separates different parts of the system, including execution, sequencing, data availability and settlement. For developers, this modularity can make the architecture easier to reason about than a completely independent blockchain with every component designed from scratch. But technology alone isn't enough This is where I think Horizen becomes particularly interesting to watch. The technical architecture is only one part of the equation. An EVM-compatible L3 can provide familiar tooling. Privacy technology can solve real problems. Lower transaction costs can make applications more accessible. But ultimately, developers need reasons to actually build on the network. The interesting question isn't whether Horizen has a different architecture. It's whether that architecture can support applications that benefit from combining EVM compatibility with privacy and compliance-oriented features. That's something adoption will have to answer. The bigger picture Horizen is a good example of how blockchain projects can evolve rather than remain tied to their original architecture. The project started with a strong focus on privacy and its own blockchain infrastructure. Today, it is building an EVM-compatible L3 on Base while continuing to focus on privacy-oriented applications. For developers, that makes Horizen less about “another cryptocurrency” and more about an experiment in combining familiar Ethereum tooling with a different approach to privacy. Whether that model becomes widely adopted remains to be seen. But the direction is definitely worth watching. Top comments (0)
