Golden Finance reported that Avalanche launched the Avalanche9000 network upgrade, which is also the largest network upgrade Avalanche has experienced since the launch of the main network. This upgrade will make it more economically feasible, easier to customize, easier to maintain and faster to market for users to launch their own L1. The Avalanche9000 test network is about to be launched, and developers will be rewarded for building the foundation of the Avalanche L1 expansion network.
