Avalanche is making significant strides with the introduction of ACP-77, a community proposal aimed at decoupling subnet validator sets from the main network. This initiative is expected to lower barriers for builders and reinvent the framework for building an L1 on Avalanche, making it as cost-effective as operating a Celestia-based rollup. The Avalanche community anticipates that these changes will make it easier and cheaper to launch custom chains, potentially positioning Avalanche as a central hub for appchains. Subnet-only validators are a key component of this proposal. EffortCapital's analysis highlights the potential of ACP-77, and projects like SuzakuNetwork are already planning to build on Avalanche.
