Aztec Network has launched its Ignition Chain, becoming the first fully decentralized Layer 2 protocol on the Ethereum mainnet. This milestone signifies a major step towards a "private world computer," allowing developers to build confidential DeFi applications. The chain's launch was triggered by reaching 500 validators, ensuring network security and block production. It combines zero-knowledge proofs with Ethereum's security for private, scalable transactions, offering speed, cost savings, and enhanced privacy.
