Avalanche successfully launched a major upgrade, Avalanche9000, on December 17. This upgrade significantly reduced the deployment cost of subnets and lowered the basic fee of the C chain from 25 nAVAX to 1 nAVAX, a decrease of up to 96%. The new Etna module supports independent operation of the chain, optimizes the validation model, and enhances cross-chain messaging capabilities. Blockworks Research predicts that after the upgrade, C chain transaction volume is expected to increase by approximately 50%, bringing positive signals to the market.
