Method and system for fraud control of blockchain-based transactions

Abstract:

A method for linking blockchain transactions to privately verified identities includes: storing account profiles, each profile including data related to a transaction account including an account identifier and account data; receiving a transaction message, the message including a first data element configured to store a personal account number, a second data element configured to store a merchant identifier, and a third data element configured to store a blockchain network identifier; identifying a first account profile that includes the personal account number; identifying a second account profile that includes the merchant identifier; receiving a transaction notification, the notification indicating a transaction processed using a blockchain network associated with the blockchain network identifier and including a transaction identifier and an address identifier associated with the first or second account profile; and storing a linkage between the transaction identifier and the address identifier, the personal account number, and/or the merchant identifier.
