The Avalanche team launched its major upgrade on the testnet on Monday, named "Avalanche9000," which includes several technical improvements aimed at reducing the blockchain deployment costs by 99.9%. These improvements include community proposals ACP-77 (to make Avalanche L1 validators more flexible) and ACP-125 (aimed at reducing Avalanche's base fees by 96%). At the same time, a $40 million retroactive grant program, Retro9000, was introduced to reward builders developing L1 blockchains and other tools on the Avalanche9000 testnet. (TheBlock)
