What is Aztec Network?

Aztec Network is the privacy-first Layer 2 solution built on Ethereum, utilizing state-of-the-art zero-knowledge cryptographic protocols to enable fully programmable smart contracts with an encrypted state ledger.

Unlike transparent blockchains that expose every transaction detail, Aztec gives developers control over data and code visibility through programmable privacy.

The network operates through client-side proving, where users execute transactions locally on their devices and submit zero-knowledge proofs to validators, ensuring sensitive information never leaves the user's control.

Built around Noir—a universal programmable cryptography language—Aztec implements a hybrid state model supporting both public and encrypted data, allowing applications to choose exactly what information should be visible.

Purpose	Infrastructure for privacy-preserving applications	Economic mechanism ensuring network security and decentralization

What Problems Does Aztec Want to Solve?

1. The Privacy Barrier to Real-World Adoption

Existing blockchains force complete transparency, making every transaction, balance, and interaction permanently public.

This "poison pill" prevents financial institutions, enterprises, and privacy-conscious users from adopting blockchain technology.

No traditional bank wants its entire portfolio visible globally, no company wants competitors tracking every business relationship, and no individual wants their financial life exposed.

Aztec solves this by introducing programmable privacy where developers control exactly what data remains confidential.

2. Information Leakage in Account-Based Models

Traditional blockchain architectures create metadata trails revealing who modified what data and when, even with encryption.

Statistical analysis tools—increasingly powered by AI—can de-anonymize users by tracking transaction patterns and storage slot modifications.

Aztec's Note-based system (similar to Bitcoin's UTXO model but for arbitrary data) ensures all state reads and writes appear indistinguishable to outside observers, preventing this information leakage.

3. Computational Limitations of Transparent Blockchains

Public blockchains require every node to re-execute every transaction, severely limiting computational complexity and creating DOS attack vectors.

This forces developers into restrictive environments where sophisticated applications become impractical.

Aztec's client-side proving allows users to perform complex computations locally, submitting only zero-knowledge proofs of correct execution—unlocking previously impossible use cases while maintaining network security.

The Story Behind Aztec Network

Aztec began in 2017 when founders pitched private debt funds on issuing corporate debt on Ethereum, encountering a dealbreaker: no financial institution would publish their entire portfolio on a transparent ledger.

This sparked an eight-year mission to build the privacy infrastructure blockchain desperately needed.

The team delivered industry-defining innovations including PLONK (2019)—now foundational to most SNARK protocols—and pioneered the largest MPC trusted setup ceremony.

After successful products like Aztec Connect served hundreds of thousands of users, the team sunseted everything in 2023 to pursue the most ambitious goal yet: a fully programmable privacy platform combining their open-source Noir language with the Aztec Network, launching decentralized from day one.

How Does Aztec Network Work?

1. Client-Side Proving with PXE

Users execute private transactions locally through the Private Execution Environment (PXE), an open-source client-side library running inside wallet software.

The PXE maintains master secret keys and private state without ever divulging them to smart contracts.

When executing private functions, PXE generates zero-knowledge proofs of correct execution and sends only these proofs—plus public function requests—to Sequencers.

Transaction details (inputs, outputs, which functions were called) never leave the user's device, ensuring true privacy.

2. Hybrid State: Public and Private

Aztec implements dual state systems within one protocol. Public state follows Ethereum's familiar account model with mutable storage slots, visible to everyone.

Private state uses an append-only Note system where encrypted data exists as single-use objects—creating a Note nullifies previous ones, but observers cannot link nullifiers to specific Notes.

Smart contracts can read and write both state types in a single transaction, letting developers choose precisely what information should be public versus encrypted.

3. Sequencer Network and Block Production

Aztec operates through decentralized Sequencers who stake AZTEC tokens to participate in block production. Time divides into slots (grouped into Epochs), where randomly selected committee members propose blocks and attest to their validity.

Blocks first appear on the Pending Chain (secured by committee stake) for fast confirmations, then graduate to the Proven Chain once zero-knowledge validity proofs are verified on Ethereum L1.

This two-phase approach delivers both speed and finality backed by cryptographic proofs.

4. Privacy Mechanisms: Notes and Nullifiers

Private state updates occur through creating and nullifying Notes—encrypted objects storing arbitrary smart-contract-defined data.

When Alice transfers tokens to Bob, she nullifies her existing Note and creates new Notes for Bob and herself.

Only Alice knows which nullifier corresponds to her original Note; to everyone else, all nullifiers and Notes appear as indistinguishable random data.

This UTXO-like pattern extends beyond transfers to represent any state, ensuring privacy at the protocol level.

Key Features of Aztec Network (AZTEC)

1. Programmable Privacy

Aztec provides developers with granular control over data visibility through its hybrid state model and Noir programming language.

Unlike all-or-nothing privacy systems, developers specify exactly which data should be public (for transparency and composability) versus private (for confidential business logic).

This flexibility enables real-world applications where certain information must remain visible for regulatory compliance while protecting sensitive user data.

The Private Execution Environment ensures private computations happen locally with cryptographic proof of correctness.

2. Zero-Knowledge Validity Proofs

The network leverages CHONK (Client-side Highly Optimised PLONK), an advanced proving system enabling efficient proof generation on consumer devices like phones and laptops.

Users prove correct execution without revealing transaction details, while the network maintains consensus guarantees identical to transparent blockchains.

Recursive proof composition through Kernel Circuits allows complex multi-function transactions to be verified efficiently, and ProtoGalaxy folding achieves cheaper recursion essential for practical mobile proving.

3. Decentralized from Day One

Unlike Layer 2s launching with centralized Sequencers, Aztec Network is decentralized at genesis through permissionless staking and distributed block production.

Sequencers join by staking AZTEC tokens and entering an entry queue, with committee selection via pseudorandom sampling.

Governance operates through Sequencer voting (requiring token staking) combined with broader token-holder ratification, ensuring decisions reflect engaged stakeholders.

This architecture provides credible neutrality essential for applications managing sensitive financial or personal data.

4. Developer-Friendly Abstractions

Noir, Aztec's programming language, abstracts zero-knowledge complexity so developers create privacy-preserving applications without cryptography expertise.

Aztec.nr framework provides familiar smart contract patterns, while the PXE handles state management, Note aggregation, and proof generation automatically.

The hybrid model supports both private functions (executed client-side) and public functions (executed by Sequencers), offering flexibility matching application needs without forcing developers into unfamiliar paradigms.

5. Cross-Chain Interoperability

Aztec connects to Ethereum L1 through Portals—independent bridge contracts enabling arbitrary message passing and asset transfers between layers.

Unlike systems with canonical bridges creating single points of failure, Portals are permissionless and operated by independent providers who set their own rules and support whichever assets they choose.

This design distributes risk while enabling private assets on Aztec to interact with Ethereum's DeFi ecosystem through privacy-preserving protocols.

Aztec Network Real-World Use Cases

Confidential DeFi: Private lending, trading, and yield farming where positions and strategies remain hidden from competitors and front-runners
Compliant Finance: Regulated institutions gate access to onchain products based on private user information (age, nationality, net worth) without exposing data publicly
Privacy-Preserving Voting: DAOs and organizations conduct governance with encrypted votes, preventing coercion while maintaining verifiable outcomes
Asymmetric Information Games: Poker, bridge, and strategy games requiring hidden information, impossible on transparent blockchains
Credential Systems: Universities, employers, and governments issue zero-knowledge attestations that users selectively reveal without exposing underlying sensitive data
Protected Activism: Opposition groups in authoritarian regimes coordinate safely using encrypted communications and voting without risking participant identification
Private Supply Chains: Enterprises track sensitive business relationships and trade secrets without revealing competitive intelligence to rivals

AZTEC Tokenomics and Distribution

The AZTEC token has a total supply of 10,350,000,000 tokens (10.35 billion), distributed to balance ecosystem growth, team compensation, and community ownership:

Token Sale (21.96% / 2.27B tokens): Open community sale optimized for wide Sequencer distribution and fair user access, conducted in two phases before Ignition launch
Ecosystem Grants (10.73% / 1.11B tokens): Long-term grants for early contributors, community members, and builders of core infrastructure or applications
Future Incentives (4.88% / 505M tokens): Sequencer-controlled pool for distribution in first 24 months, enabling network participants to incentivize growth
Foundation (11.71% / 1.21B tokens): Endowment for ongoing grants to future employees and operational funding through conversion to fiat
Insiders (48.31% / 5.0B tokens): Recognition of eight years of development, split between Team (21.06%) and Investors (27.25%), locked minimum 12 months
Year 1 Network Rewards (2.41% / 250M tokens): Pre-minted for first-year network inflation distributed to the Reward Distributor Contract

The network automatically transitions between inflationary and deflationary tokenomics based on demand.

During low usage, protocol-created rewards incentivize Sequencers and Provers.

During high congestion, excess fees are burned, potentially deflating supply.

This adaptive mechanism ensures sustainable compensation regardless of demand fluctuations.

Functions of the AZTEC Token

1. Network Security Through Staking

AZTEC tokens secure the network via mandatory staking for Sequencers, who must lock tokens as collateral to participate in block production.

Stakers earn network fees and block rewards proportional to their contribution, creating economic alignment.

The protocol implements slashing—burning up to 15% of a Sequencer's stake—for misconduct including excessive inactivity, data withholding, or proposing invalid blocks.

This crypto-economic security model ensures honest behavior without centralized enforcement.

2. Transaction Fee Payments

Users pay for blockspace in AZTEC through a "mana" system metering computational resources.

Transactions consume mana based on state created (Notes, nullifiers, logs) and operations performed in the Aztec Virtual Machine (AVM).

The base fee per mana fluctuates with Ethereum L1 costs (gas and blob fees) and congestion, ensuring Sequencers and Provers receive fair compensation.

Fee Payment Contracts enable users to pay in any token, converting automatically to AZTEC for network settlement.

3. Decentralized Governance

Token holders influence protocol evolution through a two-stage governance process.

Sequencers (who must stake tokens) initiate proposals by signaling desire for upgrades; if m/n Sequencers support within defined blocks, proposals advance to token votes.

All token holders—including those delegating to Sequencers—vote on ratification, with emergency mechanisms available for critical situations.

This structure ensures engaged stakeholders with long-term orientation guide development while maintaining broader community oversight.

The Future of Aztec Network

Aztec's launch follows a deliberate, security-focused path prioritizing decentralization over speed.

Ignition (Q4 2025) deployed L1 contracts to bootstrap the Sequencer set without user transactions.

Alpha (Q1 2026) represents the first governance-led hard fork, though frequent upgrades and critical bugs should be expected.

Mainnet Beta arrives after 90 days without critical issues plus 99% uptime—timelines remain open-ended to ensure safety.

Mainnet 1.0 marks production readiness after Beta runs successfully for sufficient duration.

Future development includes collaborative proving (coSnarks) for shared private state computation, ecosystem expansion through grants and hackathons, progressive governance decentralization to token holders, and enterprise adoption bridging traditional data systems with blockchain.

Aztec Network vs Competitors

Aztec competes in the privacy-focused Layer 2 space against projects like Polygon zkEVM, zkSync, StarkNet (offering scalability with some privacy features), and privacy-specialized protocols like Secret Network or Mina Protocol.

However, Aztec's core differentiators set it apart: Aztec distinguishes itself as a programmable privacy L2 combining client-side proving (keeping data on user devices) with a hybrid state model (supporting both public and private data), built around Noir—a language specifically designed for zero-knowledge applications.

While competitors offer privacy through encryption or ZK-rollup scalability, Aztec provides developers granular control over what stays confidential versus transparent, enabling compliance-ready applications impossible on fully private or fully public chains.

The decentralized-from-genesis architecture and protocol-enshrined account abstraction further distinguish Aztec as infrastructure for real-world adoption rather than just scalability or basic privacy.
