Avalanche has launched the Avalanche9000 network upgrade, which is also the largest network upgrade experienced since the launch of Avalanche's autonomous network. This upgrade will enable users to launch their personal L1 more economically viable, easier to customize, easier to maintain, and faster to market. The Avalanche 9000 testnet is about to launch, and developers will be rewarded for building the foundation for the Avalanche L1 extension network.
