Patent attributes
Embodiments of the invention are directed to a system, method, or computer program product for generating and using a block chain distributed network for tracking and validating the status of distributed portions of a finite resource and the obligations of users to return portions of the finite resource. In example implementations, the block chain database comprises a distributed ledger that is updated to reflect the status and availability of particular portions of the finite resource, including the fractional return of resource portions by users to whom such portion had previously been assigned. Example implementations also implement the use of queries to the block chain to validate requests for access to particular portions of a finite resource, determine the availability of the portion and verify the satisfaction of resource-return obligations incurred by users.
