# Rules to deter "stuck payment" attack in multi-hop payments

Multi-hop payments have the "stuck payment" attack problem, that any node in the payment can decide to not propagate a decision, thus causing the payment to get stuck at that node. This problem can be resolved by adding a penalty system that enforces propagation by penalizing any node that causes the payment to get stuck. As the payment can get stuck on any decision, and by any node, this penalty system consists of three mechanisms, used to account for every possible scenario.

The decisions in the payment need to move in three different ways:

1) From the buyer towards the seller, where each node who propagated the decision then leaves the payment.
2) From the seller towards the buyer, where each node who propagated the decision then leaves the payment.
3) From the buyer towards the seller, where each node who propaated the decision stays in the payment.

These movements can be eforced with two mechanisms, that are used either alone or combined. These mechanisms are:

A) "continuous finalization", all nodes continuously finalize small "chunks" of the payment
B) "continuous cancellation", all nodes continuously cancel small "chunks" of the payment

To enforce 1 you need to use mechanism A. To enforce 2, you need to use mechanism B, and to enforce 3 you need to combine A and B.

These two mechanisms can apply enforcement in either direction, and cover all scenarios except when the attacker is both the buyer and seller. This is where the third mechanisms is used. The third mechanism is the addition of fees that are paid on top of the payment by the buyer.

With these three mechanisms, the propagation of any decision is enforced at any hop.
