Systems and methods for hyperledger-based payment transactions, alerts, and dispute settlement, using smart contracts

A blockchain application server system, the system comprising:

• a memory configured to store instructions;
• and
• one or more processors configured to execute the instructions to perform operations for generating a fraud alert, the operations comprising:
• receiving, by the one or more processors, a plurality of transaction data associated with an electronic transaction from a plurality of blockchain networks of a hyperledger, wherein the plurality of transaction data includes a plurality of transaction attributes including a first transaction amount, an issuer identifier, an acquirer identifier, and a product identifier, wherein the plurality of blockchain networks of the hyperledger are linked via an addressing system, and wherein each of the plurality of blockchain networks comprises one or more first blocks that are accessible to at least one participant of the electronic transaction, the at least one participant comprising at least one of a consumer, a merchant, an issuer of a payment source account of the consumer associated with the issuer identifier, and an acquirer of a payment account of the merchant associated with the acquirer identifier;
• storing, by the one or more processors, the plurality of transaction data including the plurality of transaction attributes in a smart contract generated by a smart contract application of the plurality of blockchain networks;
• deploying, based on the smart contract application, the smart contract into the plurality of blockchain networks;
• determining, by the one or more processors and by accessing at least one blockchain network of the plurality of blockchain networks using the addressing system, that the at least one blockchain network comprises one or more second blocks including transaction data comprising at least one transaction attribute that matches at least one of the plurality of transaction attributes;
• generating, by the one or more processors, a blockchain entry locked with a crypto private key in a shared ledger of the plurality of blockchain networks, wherein the blockchain entry comprises encrypted dispute information associated with the at least one transaction attribute, a timestamp, and a link to a previous blockchain entry;
• generating, by the one or more processors, a fraud alert based on generating the blockchain entry;
• and
• transmitting, by the one or more processors, a blockchain analytics report including the fraud alert to a display of a computing device.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform a method for generating a fraud alert by a blockchain application server, the method comprising:

• receiving, by the one or more processors, a plurality of transaction data associated with an electronic transaction from a plurality of blockchain networks of a hyperledger, wherein the plurality of transaction data includes a plurality of transaction attributes including a first transaction amount, an issuer identifier, an acquirer identifier, and a product identifier, wherein the plurality of blockchain networks of the hyperledger are linked via an addressing system, and wherein each of the plurality of blockchain networks comprises one or more first blocks that are accessible to at least one participant of the electronic transaction, the at least one participant comprising at least one of a consumer, a merchant, an issuer of a payment source account of the consumer associated with the issuer identifier, and an acquirer of a payment account of the merchant associated with the acquirer identifier;
• storing, by the one or more processors, the plurality of transaction data including the plurality of transaction attributes in a smart contract generated by a smart contract application of the plurality of blockchain networks;
• deploying, based on the smart contract application, the smart contract into the plurality of blockchain networks;
• determining, by the one or more processors and by accessing at least one blockchain network of the plurality of blockchain networks using the addressing system, that the at least one blockchain network comprises one or more second blocks including transaction data comprising at least one transaction attribute that matches at least one of the plurality of transaction attributes;
• generating, by the one or more processors, a blockchain entry locked with a crypto private key in a shared ledger of the plurality of blockchain networks, wherein the blockchain entry comprises encrypted dispute information associated with the at least one transaction attribute, a timestamp, and a link to a previous blockchain entry;
• generating, by the one or more processors, a fraud alert based on generating the blockchain entry;
• and
• transmitting, by the one or more processors, a blockchain analytics report including the fraud alert to a display of a computing device.
