Tokenized asset backed by government bonds and identity and risk scoring of associated token transactions

摘要

A method for facilitating the exchange of a stable cryptocurrency collateralized by government-issued debt. First granularity parameters are received through a first wallet interface of a first digital wallet. A first restricted use key is generated based upon the first granularity parameters and provided to an owner of a second digital wallet. A second restricted use key is generated based upon second granularity parameters received through a second wallet interface associated with the second digital wallet. Information from a blockchain wallet is accessed using the second restricted use key wherein the information relates to one or more of an ID classification and risk score of the second wallet owner at a level of detail determined by the second granularity parameters. An indication to proceed with a transaction between the first digital wallet and the second digital wallet may then be received through the first wallet interface.
