Abstract

Described herein is a system in which an electronic record is stored within a distributed environment. In this system, a validation node may receive a transaction record from an acceptance node. The validation node may verify that the acceptance node is authorized 5 to participate in a blockchain network, identify a user associated with the transaction record, and append the transaction record toan electronic record. The transaction record may be associated with a digital signature formed by hashing multiple data elements, and then encrypting the hashed data elements using a private encryption key.

Description

Background technique [0001] Before a resource provider completes a transaction with a user, the resource provider is generally expected to determine the risk level of the transaction. For example, a banking institution may wish to assess the risks associated with extending a line of credit to a particular individual or business. In conventional systems, resource providers may consult credit bureaus or other entities to determine each user's risk level. [0002] However, such credit bureaus and other entities may constitute only a single source of information. As a result, retrieving data from such entities can be slow and cumbersome. In addition, data held by such entities may be corrupted or erroneous due to human error or computer failure. Accordingly, there is a need for improved systems and methods that address these issues. [0003] Embodiments of the present invention address these and other problems individually or collectively. Contents of the invention [0004]...
