Aztec Network’s privacy-focused Layer 2 solution, the Alpha Network, went live on the Ethereum mainnet on March 31, 2026, introducing private smart contracts to the ecosystem. The launch marks a significant step toward enabling confidential transactions and decentralized applications on Ethereum.
According to the official announcement from Aztec, the Alpha Network is designed to integrate native privacy into smart contracts. This allows for data, identity, and computation to remain confidential, addressing a key demand for many blockchain use cases.
The network operates as a Layer 2 rollup, bundling transactions off-chain to reduce fees and increase throughput while inheriting the security of the Ethereum mainnet. Smart contracts on Aztec are written in Noir, a purpose-built language for creating private applications that use zero-knowledge proofs. This technical deployment ensures that the details of user interactions with dApps can be shielded from public view.
The introduction of a privacy-centric Layer 2 is expected to attract a new class of developers and users to the Ethereum ecosystem, particularly for applications in decentralized finance (DeFi), digital identity, and private communications where confidentiality is critical. The move will likely increase competition among the growing number of Layer 2 solutions, each offering different trade-offs in terms of scalability, security, and privacy.
