Aztec Network, a ZK-rollup based Ethereum Layer 2 solution focused on privacy, has officially launched its private testnet. This milestone marks a significant step towards the mainnet launch after over eight years of development. The private testnet serves as the final verification phase, rigorously testing the network's functionality and security before being deployed for public use. Aztec aims to bring scalable privacy to Ethereum, allowing users to transact and interact with DeFi applications without revealing their data. In 2022, Aztec secured $100 million in Series B funding led by a16z, highlighting investor confidence in the project's potential to revolutionize Ethereum privacy. The launch of the private testnet represents a crucial step toward realizing that vision. ```
