In the dominant economic system, exchanges are characterized by a permanent need for equivalence. For each manufactured product, and each service, an equivalent counterparty is expected. In order to reach this equality and facilitate the assessment of the counterparty, we use money as an intermediate. The classic economy has allowed exchanges between individuals, who do not necessarily trust each other, to multiply, since the compensation perceived was considered as reliable and safe. This economy model has offered an international framework for trade, supported by currencies (solid and stable) and by contractual laws (fixing faults).
