PANews reported on December 17 that according to The Block, Avalanche announced that it has launched the Avalanche9000 upgrade, which significantly reduces the cost of deploying "subnet" blockchains and running smart contracts, while optimizing the verification mode and reducing the basic fee of the C chain (from 25 nAVAX to 1 nAVAX). This upgrade supports independent operation of the chain through the "Etna" module, significantly reducing project startup costs and meeting different regulatory requirements. The Avalanche Foundation previously raised $250 million to support the upgrade deployment, and it is expected that hundreds of primary blockchains will be launched in the coming months.
