Each person sets a trust index, how much credit they “recycle”, in percentage from 0% to 100% (100% becomes a gift economy, 0% similar to capitalism), and in an exchange, the lowest trust index is used, “taxes” the IOU and triggers swarm redistribution, as well as imprints itself on the credit line, which shapes how it will receive swarm redistribution.
With symmetric swarm redistribution, the trust index of credit lines is used so that if two people have debt to you, and one has a credit line with an index of 2%, the other of 1%, then during swarm redistribution as you propagate the “pulse”, symmetrically, the first one will receive 2x as much as the other one. They will then continue the “pulse” based on the total amount of debt they were forgiven, and based on the trust indices of people who have credit lines to them.
