B-INDEX DISTRIBUTION · 184 PLATFORMS
WHAT IS THE BLACK HOLE INDEX?

BHI is a standardised score measuring how costly it is for a user, organisation, or counterparty to depart a platform — capturing the structural friction of leaving rather than the value of staying.

It is computed as the ratio of capture pressure over escape capacity, evaluated across eleven measurable parameters and re-released every quarter under a transparent rubric.

B = Capture(D, M, A, P, N, C) ÷ Escape(Po, Sb, Hf) · adjusted for organisational depth and momentum
