Current obstacles

Sequencer latencyBlock times of 36-72 seconds in early 2026 must drop to 4 seconds, requiring better coordination between distributed sequencers.
Developer adoption of NoirThe language is new; developers must learn it despite its Rust-like design for non-cryptographers.

Physics limits

Privacy-performance trade-offZero-knowledge proofs are computationally expensive. Faster proofs require more powerful hardware or less privacy leakage.
Client-side execution limitsUsers must run code locally; slow or old devices become a bottleneck, limiting the practical throughput of private transactions.

How it works

3 parts

Private functions

Execute on your device

Smart contract functions marked private run on user hardware, not the network. The user submits zero-knowledge proofs to prove the computation is correct.

Public functions

Settle on-chain

Public functions run on the network like normal smart contracts, but can read the results of private functions via proofs.

Sequencers

Distributed block production

3,400+ sequencers across five continents produce blocks without central authority, voted in by $AZTEC stake.

About Aztec Labs

The team behind Aztec Network

Aztec Labs

Privacy ZK rollup, Noir language

Aztec Labs develops Aztec Network, a privacy-first Layer 2 on Ethereum using zero-knowledge proofs. Private functions execute client-side, keeping user data off-chain. The company also created Noir, a Rust-inspired programming language for building ZK applications.

Aztec Network went live in November 2025 and had 3,400+ sequencers across five continents by early 2026.
The December 2025 community token sale raised $61M from 16,700+ participants at a 75% discount to Series B valuation.
Noir, a Rust-inspired language for ZK applications, reached pre-release in December 2025 with 600+ GitHub projects using it.
