Abstract:

Disclosed herein are system, method, and computer program product embodiments for managing point-based transactions backed by the intrinsic value of physical objects. In some embodiments, a transaction ledger system may manage a point-based currency backed by transactions corresponding to the intrinsic value of a physical object. The transaction ledger system may use an appraisal process to estimate a point value for the physical object. The transaction ledger system may also use an authentication process to provide consumer confidence that the physical good is authentic. The transaction ledger system may also manage sensor tag serial codes, such as radio-frequency identification (RFID) serial codes, to quickly verify authenticity when the physical object is resold. When executing transactions, the transaction ledger system may record transaction and point exchange data on a centralized and immutable ledger to prevent malicious attackers from falsifying data.
