Abstract: An incentive mechanism for encouraging the adoption and use of a communally useful entity. Use of the communally useful entity is tracked. An incentive payment to be paid by an incentive provider to a recipient is calculated, the recipient being the designee of a user of the communally useful entity, and the incentive payment proportionate to a measure of the user's use of the communally useful entity. The incentive provider is directed to distribute the incentive payment to the recipient, and an amount of rights to participation in the communally useful entity is distributed to the incentive provider's designee, where the amount of rights to participation distributed is proportionate to the value of the incentive payment made by the incentive provider. Thus, the user is given an incentive to use the transaction platform, and the incentive provider is given an incentive to encourage others use of the transaction platform. A software program and computer-based system are also disclosed.
