Golden Finance reported that Layer 1 blockchain Avalanche announced the launch of the Avalanche9000 upgrade on Monday. This upgrade introduces many new features, including improvements that make it easier to launch "subnet" blockchains and run smart contracts cheaper. It is reported that Avalanche9000 is the largest upgrade of the network so far. This update contains improvement proposals ACP-77 (which changes the way validators operate) and ACP-125 (which reduces the base fee of the Avalanche main "C-chain" network). "This is the beginning of hundreds of Avalanche L1 rollouts," the team wrote on Explosive growth in emissions.”
