The signal cap is applied at the shale settlement and visible in the vault breakdown, which turns a pooling attack into a slow, expensive and publicly visible grind. Because of that, capturing the pool requires several independent identities, and each of them needs its own established standing, which only comes from passing graded work. A single identity may take at most 30% of an epoch's reward pool; anything above the cap is repooled or burned. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.
