Avalanche developers have introduced the Avalanche9,000 testnet, a major upgrade aimed at simplifying and reducing costs for L1 development on the network. The upgrade, which recently went live, includes $40 million in retroactive grants for builders, with a focus on stimulating growth and adoption. Scheduled for full implementation on the mainnet in 2025, the upgrade will bring various cost-saving measures, such as lower fees and fewer capital requirements for validators. Additionally, the upgrade introduces Avalanche L1s, project-specific chains operating independently from the mainnet, to enhance customization and maintenance activities. The network is already seeing over 500 L1s in development, with plans for further expansion through Interchain Messaging. The grant programs will be determined through community voting, encouraging developers to create public projects and earn rewards. Read more AI-generated news on: https://app.chaingpt.org/news
