Ever wondered how Ethereum can scale without waiting years between major upgrades? That's where BPO forks come into play.

BlobParameterOnly forks represent a fresh approach introduced in the Fusaka upgrade. Instead of bundling all network improvements into a single massive upgrade cycle, BPO forks enable the Ethereum network to independently adjust specific parameters—such as blob targets—on a more flexible timeline.

This mechanism essentially decouples parameter tuning from monolithic upgrade schedules. It means network capacity adjustments can happen more frequently and responsively, giving Ethereum better agility when responding to real-world demand. Think of it as fine-tuning the network's capacity dials without dismantling the whole machine.
