Avalanche has launched its most significant upgrade since the mainnet launch, introducing the Avalanche9000 on the Fuji testnet and unlocking over $40 million in retroactive rewards for its community. Expected to enhance deployment efficiency by reducing costs by 99.9%, the upgrade facilitates interchain communication and is underpinned by technical advancements from the Etna Upgrade along with community-driven proposals ACP-77 and ACP-125. A notable change is rebranding Avalanche’s subnets to layer-1s, maintaining their horizontal scaling capabilities while decentralizing validator management. The upgrade allows L1 networks to operate either as permissionless or permissioned, boosting independence in setting validator rules and incentives. Furthermore, the lengthy staking requirement for validators has been eliminated, streamlining participation costs. According to Avalanche, over 500 L1s are currently in development, covering a variety of applications including gaming and payment solutions. This upgrade aims to improve interoperability for developers, as Avalanche's total value locked stands at $1.4 billion, significantly lower than its peak of $11.1 billion in November 2021.
