What Is Zama?

Zama is a privacy-focused blockchain infrastructure company building the Zama Network to make confidential computing possible on public blockchains. If you understand the blockchain basics, you already know that transparency is both a strength and a limitation. Zama works on the missing layer by letting encrypted smart contracts process encrypted data without exposing it on-chain.

Zama reached a major milestone by becoming the first company focused on fully homomorphic encryption to achieve unicorn status, following a funding round that brought in $57 million. It crossed a valuation above $1 billion in June 2025, becoming the first unicorn built entirely around fully homomorphic encryption. That milestone followed a strong Series B funding round backed by Pantera Capital, signaling serious confidence from institutional crypto investors.

Rather than creating a closed system, the Zama Network aims to plug into existing blockchains and developer workflows. This approach helps teams build confidential applications that keep balances, encrypted inputs, and logic private while staying decentralized and verifiable. Zama positions itself at the intersection of privacy, compliance, and real-world blockchain adoption.

What Problem Does Zama Solve?

Public blockchains expose customer data by design. Every balance, transaction detail, and smart contract input sits in plain view, which creates serious limits for real financial, enterprise, and institutional use. Users lose privacy, businesses cannot protect sensitive logic, and regulators struggle to support compliant systems built on fully transparent ledgers. This gap slows adoption and forces developers to choose between decentralization and confidentiality.

Zama’s technology addresses this problem by allowing smart contracts to compute directly on encrypted data. Instead of hiding activity off-chain or relying on trust assumptions, applications keep information confidential while still running on public networks. This approach protects user balances, transaction amounts, and business rules without breaking composability or auditability.

Without native confidentiality, many use cases simply do not work on-chain, including private payments, compliant identity systems, and enterprise data processing. Zama’s technology removes this barrier and makes it possible to build applications that respect privacy while staying decentralized, verifiable, and usable at scale.

How Does Zama Work?

Zama operates using fully homomorphic encryption (FHE), a groundbreaking method that allows encrypted values to be processed without decryption. This ensures that sensitive information remains secure throughout its entire lifecycle, even during computation.

The foundation of Zama’s technology lies in its core architecture, which includes programmable bootstrapping. This feature enables efficient and scalable encrypted computations, making it practical for real-world applications. 

Encrypted data types in encrypted smart contracts further enhance privacy by allowing developers to build secure applications without exposing customer data. Threshold decryption is another key component, ensuring that only authorized parties can access decrypted results. This combination of advanced encryption techniques and blockchain integration makes Zama a powerful tool for industries requiring high levels of data confidentiality, such as finance, healthcare, and artificial intelligence.

Fully Homomorphic Encryption (FHE) Explained

Fully homomorphic encryption allows computations to run directly on encrypted values without exposing the original values at any point. For blockchain applications, this removes the need to reveal balances, inputs, or business logic just to execute a smart contract. The Zama Protocol uses FHE so applications can process sensitive information on public networks while keeping that data private by default. This foundation also opens the door for economic incentives, since secure computation creates new roles for validators and participants, which is where tokenomics may apply to Zama becomes relevant.

FHE alone is not enough to support real applications at scale. The confidentiality protocol must translate advanced cryptography into a system that developers can actually use, which leads directly into how Zama structures its core architecture.

Zama Core Architecture

The Zama Protocol combines FHE with blockchain execution to support smart contracts that operate entirely on encrypted data. Developers interact with familiar programming models, while the network handles encrypted computation, verification, and controlled decryption. This structure allows privacy to coexist with decentralization and composability, and it also creates clear points where incentives and protocol fees can align with network usage and security.

1. Programmable Bootstrapping

Programmable bootstrapping refreshes encrypted circuits values during computation so contracts can run complex logic without losing accuracy. Zama applies this technique to support conditional logic and repeated confidential operations inside smart contracts. As usage grows, this process becomes a measurable resource, which helps explain how tokenomics may apply to Zama through computation costs and network rewards.

2. Encrypted Data Types in Smart Contracts

Zama provides encrypted data types that behave like standard variables while keeping their contents hidden. Smart contracts can store, compare, and update these values without ever revealing them on-chain. This feature makes privacy native to application design and creates demand for secure execution, which can be priced and incentivized through the protocol’s economic model.

3. Threshold Decryption

Threshold decryption splits decryption authority across multiple participants so no single entity controls access to sensitive results. Only when a required group cooperates can the final output be revealed. This design strengthens security and supports decentralized trust, while also defining roles that may earn rewards, further showing how tokenomics may apply to Zama as the network matures.

Key Features of the Zama Protocol

As privacy moves from a nice-to-have to a real requirement, Zama focuses on building practical tools that developers and businesses can actually use. The confidential protocol does not treat confidentiality as an add-on. It builds it directly into how specialized smart contract engines execute and interact. Here are the key features that define the Zama Protocol and explain why it stands out.

1. Native Encrypted Computation

Zama allows smart contracts to compute directly on encrypted data. Encrypted inputs, states, and outputs remain confidential throughout execution. This design removes the need to reveal sensitive information just to use a decentralized application, while still preserving correctness and verifiability on-chain.

2. Open-Source Cryptographic Framework

The Zama Protocol follows an open source cryptography company model, giving developers and researchers full visibility into its cryptographic components. This approach encourages audits, community contributions, and long-term trust. By keeping the core technology open-source, Zama supports transparency at the protocol level while protecting user data at the application level.

3. Developer-Friendly Smart Contract Integration

Zama provides encrypted data types and tooling that fit into familiar smart contract workflows. Developers do not need to redesign applications from scratch to support privacy. They can build using established patterns while the protocol handles encrypted computation behind the scenes.

4. Decentralized and Secure Decryption

The Zama protocol operates on a threshold-based mechanism to control how and when encrypted results become readable. No single participant can decrypt sensitive data alone. This structure reduces trust assumptions and aligns with decentralized security principles.

5. Composability With Existing Blockchains

Zama designs its technology to work alongside existing blockchain networks rather than replacing them. Applications can remain interoperable while gaining compliant confidentiality, making it easier to integrate encrypted data into broader decentralized ecosystems.
