Blast Radius

mental-model

Failures propagate through shared dependencies and transaction links, reaching people who did nothing to cause the original problem. Risk therefore depends not only on your actions, but on what—and whom—you are connected to.

Tainted money passed through several hands. Three steps later, someone unrelated to the original wrongdoing received it—and had their entire bank account frozen for months.

Trouble travels along the links

A system responding to fraud does not stop at the first bad actor. It follows the transaction chain, and every connected account can enter the zone of suspicion or containment. The blast radius is the set of people and resources a failure can reach through those links.

That makes exposure different from culpability. You may have done nothing wrong and still lose access to something critical because the system cannot immediately distinguish an innocent downstream recipient from part of the original scheme.

Where it shows up

Three steps from the source

The frozen account shows how distance can create false reassurance: several intervening transactions did not prevent the consequences from propagating to an unrelated recipient.

Connection is not guilt

A transaction link can justify investigation or temporary containment, but it does not establish responsibility. The model explains how harm spreads; it does not prove that every affected person participated in the original wrongdoing.

Map what can be frozen with it

List the accounts and payment paths you depend on for essential expenses, then identify which ones share counterparties or transaction flows. If one link were flagged tomorrow, know exactly which necessities would become inaccessible.
