Avalanche is rolling out its biggest upgrade since its mainnet debut, with Avalanche9000 now live on the Fuji testnet and a mainnet launch on the horizon. This upgrade slashes deployment costs by 99.9%, enhances interchain communication, and unlocks over $40 million in rewards for developers. Key changes include rebranding subnets as layer-1s and shifting validator management from the centralized P-Chain to individual L1s via a ValidatorManager smart contract. This move aims to boost decentralization and independence. Over 500 L1s are in development, spanning gaming, payments, and research.
