Positive feedback amplifies. Negative feedback stabilises.
Growth and control are one design problem, not two.
The mechanism is ordinary; the consequence is not. A user receives value. They show evidence of it. Someone sees the evidence, becomes curious, tests the system, gets their own result, and shows that. The loop tightens. That is amplification.
But the same loop carries whatever is travelling through it. Fraud amplifies. Manipulation amplifies. Low-quality participation amplifies. So the system needs something pushing the other way — identity checks, proof review, trust thresholds, withdrawal checks, limits, reputation.
The part people miss
Growth cannot be understood separately from control, and control cannot be understood separately from growth. The work is not choosing between them. It is designing the relationship between them.
