what's Anza?
Anza is a software development firm specializing in the Solana blockchain ecosystem. Founded by former Solana Labs executives and engineers, it focuses on building and maintaining core infrastructure to enhance Solana's performance, scalability, and resilience. Key contributions include the development of the Agave validator client, a fork of the original Solana validator, which aims to diversify the network's client implementations and reduce centralization risks. Anza also engages in protocol research and upgrades, such as proposing major consensus changes like Alpenglow, which introduces a new voting-based mechanism to drastically reduce block finality times. The firm operates as a key contributor to Solana's open-source development, participating in governance through Solana Improvement Documents (SIMDs) and collaborating with validators and other ecosystem builders to drive network evolution.
Anza featured at Solana Money Summit after completing multicast tech testing with Jito and Temporal.
