[Privacy Chain Aztec Network Launches Alpha Mainnet] According to Golden Finance, on April 1, the privacy chain Aztec Network, supported by a16z, officially launched the AlphaNetwork, becoming the first Ethereum Layer 2 with a fully private smart contract execution environment, previously unanimously approved through community governance voting. Aztec integrates privacy into three levels: private data supports confidential transactions and RWA transfers; private identity allows selective disclosure to meet compliance requirements; and private computation hides on-chain activities, paving the way for private DeFi and gaming applications. Contracts are written in the Rust-style language Noir, with privacy logic executed on the user side to generate zero-knowledge proofs, settling approximately every 12 seconds on Ethereum. However, this launch comes with a major warning: Aztec disclosed known critical security vulnerabilities, with auditing work still ongoing. The team advises users to only deposit funds they can afford to lose.
