The present disclosure relates to the processing of a multi-account check for a payment transaction involving a blockchain, specifically the use of a blockchain to store data related to checks that are drawn on multiple transaction accounts and the processing of a payment transaction funded via such a check.
As technology has improved, many payment methods utilized by consumers to fund payment transactions have similarly improved. For instance, payment cards have become more sophisticated and secure, due to improvements such as integrated circuit chips, account controls, and cards with physical switches to turn on or off the card and select the account to use. Likewise, mobile computing devices are configured to operate as payment instruments, and are being frequently updated with new features for use by consumers. However, checks have remained largely unchanged since their inception. The technology involved in the making of a check as well as the processing of a transaction funded via a check has had very little development in recent decades.
Many consumers desire convenience when utilizing a payment instrument. Payment cards provide convenience in their ease of use in addition to being compact and easy to care. Electronic wallets provide convenience in the ability to have multiple payment instruments utilized from a single mobile device, which the consumer is often already accustomed to carrying. Currently, checks lack in such convenience, particularly in cases where a consumer may desire to use multiple transaction accounts to fund a transaction. In traditional transactions, the consumer would be required to carry multiple checks, to independently fill out each of the checks, and present all of the checks to the merchant for processing of the transaction. For most consumers, filling out even a single check is already a lengthy process that takes longer than using any other payment instrument, so thus the prospect of having to fill out multiple checks is increasingly negative. In addition, the writing of multiple checks introduces additional opportunities for human error.
Thus, there is a need for a technological solution to enable a single check to be processed that draws on multiple transaction accounts for funding thereof, negating the need for a consumer to carry and fill out multiple checks.
The present disclosure provides a description of systems and methods for processing a multi-account check in a payment transaction. Issuing institutions that issue checks to a consumer, or the consumer themselves, may register their issued checks. A unified, multi-account check is issued by a third party with the underlying information stored on a blockchain for security and to prevent any potential fraud on the part of the consumers or issuing institutions. The consumer is then free to use the multi-account check as a standard check in a payment transaction. Processing of the transaction leads to the transaction being routed to the third party, which can then independently process the transaction on every one of the underlying accounts, accomplishing the funding of the transaction via multiple transaction accounts using a single, unified check. This enables a consumer to conduct a payment transaction funded via multiple accounts through a single check, increasing efficiency when at a register, decreasing the opportunity for human error in the payment process, and providing greater convenience to the consumer.
A method for processing a multi-account check includes: receiving, by a receiver of a processing server, a first authorization request transmitted via payment rails, wherein the first authorization request is formatted according to one or more standards and includes a plurality of data elements configured to store transaction data, the transaction data including at least a transaction amount, an account identifier, and a check number; identifying, by a processing device of the processing server, a blockchain associated with the account identifier, wherein the blockchain includes a plurality of blocks, each block includes a block header and one or more blockchain data values, and a blockchain data value included in one of the plurality of blocks includes the check number; generating, by the processing device of the processing server, two or more additional authorization requests, wherein each of the additional authorization requests are formatted according to the one or more standards and includes a plurality of data elements configured to store at least a payment amount, an alternate account number, and an alternate check number, the alternate account number included in each of the additional authorization requests is unique among the additional authorization requests, and a total of the payment amount included in each of the additional authorization requests is based on the transaction amount; and electronically transmitting, by a transmitter of the processing server, each of the generated two or more additional authorization requests to a financial institution associated with the alternate account number included in the respective additional authorization request.
Another method for processing a multi-account check includes: receiving, by a receiver of a processing server, a first authorization request transmitted via payment rails, wherein the first authorization request is formatted according to one or more standards and includes a plurality of data elements configured to store transaction data, the transaction data including at least a transaction amount, an account identifier, and a check number; identifying, by a processing device of the processing server, a blockchain associated with the account identifier, wherein the blockchain includes a plurality of blocks, each block includes a block header and one or more blockchain data values, and a blockchain data value included in one of the plurality of blocks includes the check number; generating, by the processing device of the processing server, two or more blockchain transaction requests, wherein each blockchain transaction request includes at least a recipient blockchain address, a funding blockchain address, and a payment amount, where the recipient blockchain address is generated using the same public key for each blockchain transaction request, and a total of the payment amount included in each of the blockchain transaction requests is based on the transaction amount; and electronically transmitting, by a transmitter of the processing server, each of the two or more blockchain transaction requests to a node in a blockchain network associated with a separate blockchain.
A system for processing a multi-account check includes: a receiver of a processing server configured to receive a first authorization request transmitted via payment rails, wherein the first authorization request is formatted according to one or more standards and includes a plurality of data elements configured to store transaction data, the transaction data including at least a transaction amount, an account identifier, and a check number; a processing device of the processing server configured to identify a blockchain associated with the account identifier, wherein the blockchain includes a plurality of blocks, each block includes a block header and one or more blockchain data values, and a blockchain data value included in one of the plurality of blocks includes the check number, and generate two or more additional authorization requests, wherein each of the additional authorization requests are formatted according to the one or more standards and includes a plurality of data elements configured to store at least a payment amount, an alternate account number, and an alternate check number, the alternate account number included in each of the additional authorization requests is unique among the additional authorization requests, and a total of the payment amount included in each of the additional authorization requests is based on the transaction amount; and a transmitter of the processing server configured to electronically transmit each of the generated two or more additional authorization requests to a financial institution associated with the alternate account number included in the respective additional authorization request.
Another system for processing a multi-account check includes: a receiver of a processing server configured to receive a first authorization request transmitted via payment rails, wherein the first authorization request is formatted according to one or more standards and includes a plurality of data elements configured to store transaction data, the transaction data including at least a transaction amount, an account identifier, and a check number; a processing device of the processing server configured to identify a blockchain associated with the account identifier, wherein the blockchain includes a plurality of blocks, each block includes a block header and one or more blockchain data values, and a blockchain data value included in one of the plurality of blocks includes the check number, and generate two or more blockchain transaction requests, wherein each blockchain transaction request includes at least a recipient blockchain address, a funding blockchain address, and a payment amount, where the recipient blockchain address is generated using the same public key for each blockchain transaction request, and a total of the payment amount included in each of the blockchain transaction requests is based on the transaction amount; and a transmitter of the processing server configured to electronically transmit each of the two or more blockchain transaction requests to a node in a blockchain network associated with a separate blockchain.

It should be understood that the detailed description of exemplary embodiments are intended for illustration purposes only and are, therefore, not intended to necessarily limit the scope of the disclosure.
Blockchain—A public ledger of all transactions of a blockchain-based currency. One or more computing devices may comprise a blockchain network, which may be configured to process and record transactions as part of a block in the blockchain. Once a block is completed, the block is added to the blockchain and the transaction record thereby updated. In many instances, the blockchain may be a ledger of transactions in chronological order, or may be presented in any other order that may be suitable for use by the blockchain network. In some configurations, transactions recorded in the blockchain may include a destination address and a currency amount, such that the blockchain records how much currency is attributable to a specific address. In some instances, the transactions are financial and others not financial, or might include additional or different information, such as a source address, timestamp, etc. In some embodiments, a blockchain may also or alternatively include nearly any type of data as a form of transaction that is or needs to be placed in a distributed database that maintains a continuously growing list of data records hardened against tampering and revision, even by its operators, and may be confirmed and validated by the blockchain network through proof of work and/or any other suitable verification techniques associated therewith. In some cases, data regarding a given transaction may further include additional data that is not directly part of the transaction appended to transaction data. In some instances, the inclusion of such data in a blockchain may constitute a transaction. In such instances, a blockchain may not be directly associated with a specific digital, virtual, fiat, or other type of currency.
Payment Network—A system or network used for the transfer of money via the use of cash-substitutes for thousands, millions, and even billions of transactions during a given period. Payment networks may use a variety of different protocols and procedures in order to process the transfer of money for various types of transactions. Transactions that may be performed via a payment network may include product or service purchases, credit purchases, debit transactions, fund transfers, account withdrawals, etc. Payment networks may be configured to perform transactions via cash-substitutes, which may include payment cards, letters of credit, checks, transaction accounts, etc. Examples of networks or systems configured to perform as payment networks include those operated by MasterCard®, VISA®, Discover®, American Express®, PayPal®, etc. Use of the term “payment network” herein may refer to both the payment network as an entity, and the physical payment network, such as the equipment, hardware, and software comprising the payment network.
Payment Rails—Infrastructure associated with a payment network used in the processing of payment transactions and the communication of transaction messages and other similar data between the payment network and other entities interconnected with the payment network that handles thousands, millions, and even billions of transactions during a given period.

For example, the payment rails may include specifically configured computing devices that are specially configured for the routing of transaction messages, which may be specially formatted data messages that are electronically transmitted via the payment rails, as discussed in more detail below.
Transaction Account—A financial account that may be used to fund a transaction, such as a checking account, savings account, credit account, virtual payment account, etc. A transaction account may be associated with a consumer, which may be any suitable type of entity associated with a payment account, which may include a person, family, company, corporation, governmental entity, etc. In some instances, a transaction account may be virtual, such as those accounts operated by PayPal®, etc.
Merchant—An entity that provides products (e.g., goods and/or services) for purchase by another entity, such as a consumer or another merchant. A merchant may be a consumer, a retailer, a wholesaler, a manufacturer, or any other type of entity that may provide products for purchase as will be apparent to persons having skill in the relevant art. In some instances, a merchant may have special knowledge in the goods and/or services provided for purchase. In other instances, a merchant may not have or require any special knowledge in offered products. In some embodiments, an entity involved in a single transaction may be considered a merchant. In some instances, as used herein, the term “merchant” may refer to an apparatus or device of a merchant entity.
Issuer—An entity that establishes (e.g., opens) a letter or line of credit in favor of a beneficiary, and honors drafts drawn by the beneficiary against the amount specified in the letter or line of credit. In many instances, the issuer may be a bank or other financial institution authorized to open lines of credit. In some instances, any entity that may extend a line of credit to a beneficiary may be considered an issuer. The line of credit opened by the issuer may be represented in the form of a payment account, and may be drawn on by the beneficiary via the use of a payment card. An issuer may also offer additional types of payment accounts to consumers as will be apparent to persons having skill in the relevant art, such as debit accounts, prepaid accounts, electronic wallet accounts, savings accounts, checking accounts, etc., and may provide consumers with physical or non-physical means for accessing and/or utilizing such an account, such as debit cards, prepaid cards, automated teller machine cards, electronic wallets, checks, etc.
Payment Transaction—A transaction between two entities in which money or other financial benefit is exchanged from one entity to the other. The payment transaction may be a transfer of funds, for the purchase of goods or services, for the repayment of debt, or for any other exchange of financial benefit as will be apparent to persons having skill in the relevant art. In some instances, payment transaction may refer to transactions funded via a payment card and/or payment account, such as credit card transactions. Such payment transactions may be processed via an issuer, payment network, and acquirer. The process for processing such a payment transaction may include at least one of authorization, batching, clearing, settlement, and funding. Authorization may include the furnishing of payment details by the consumer to a merchant, the submitting of transaction details (e.g., including the payment details) from the merchant to their acquirer, and the verification of payment details with the issuer of the consumer's payment account used to fund the transaction. Batching may refer to the storing of an authorized transaction in a batch with other authorized transactions for distribution to an acquirer. Clearing may include the sending of batched transactions from the acquirer to a payment network for processing. Settlement may include the debiting of the issuer by the payment network for transactions involving beneficiaries of the issuer. In some instances, the issuer may pay the acquirer via the payment network. In other instances, the issuer may pay the acquirer directly. Funding may include payment to the merchant from the acquirer for the payment transactions that have been cleared and settled. It will be apparent to persons having skill in the relevant art that the order and/or categorization of the steps discussed above performed as part of payment transaction processing.
System for Multi-Account Check Processing
The system 100 may include a processing server 102. The processing server 102, discussed in more detail below, may be configured to provide a series of multi-account checks 114 to a consumer 104 that can be used to fund a payment transaction via multiple transaction accounts that are associated therewith. In the system 100, the consumer 104 may have multiple transaction accounts issued thereto by one or more issuing institutions 106. Each issuing institution 106 may be a financial institution or other entity configured to issue transaction accounts that may be used to fund electronic payment transactions. As part of the issuing of a transaction account to the consumer 104, each of the issuing institutions 106 may issue a series of traditional checks 108 to the consumer 104 associated with an issued transaction account. A traditional check 108 may be a payment instrument that, when presented to a merchant system 110 as part of the payment of a payment transaction, the transaction is funded via the corresponding transaction account.
In a payment transaction where a traditional check 108 is used, the traditional check 108 may be presented to the merchant system 110, which may read an account number and routing number therefrom, such as using a magnetic ink reader configured to read the data printed on the traditional check 108 using magnetic ink. The account number and routing number may be provided to a payment network 112, discussed in more detail below, which may process the payment transaction. Part of the processing of the payment transaction may include routing the transaction data to the issuing institution 106 that issued the traditional check 108 used in the transaction using the routing number, where the issuing institution 106 may then approve or deny the transaction (e.g., based on amount of available funds in the transaction account associated with the traditional check 108).
In the system 100, the consumer 104 may be issued a plurality of different sets of traditional checks 108, where each set is associated with a different transaction account. The consumer 104 may have a desire to use a single check in place of presenting multiple checks in order to fund a payment transaction through multiple transaction accounts. The consumer 104 may request a multi-account check 114 from the processing server 102. The request may be submitted to the processing server 102 using a suitable communication network and method. For instance, the consumer 104 may use a computing device (e.g., smart phone, wearable computing device, desktop computer, tablet computer, laptop computer, etc.) to submit a request to the processing server 102 via a web page, application program, or other interface associated therewith. The consumer 104 may provide account details for each of the transaction accounts to which the consumer 104 wants the multi-account check 114 to be associated.
In some cases, the account details may include the data printed on each of the traditional checks 108 (e.g., routing numbers, account numbers, check numbers). In other cases, the account details may include identifying information and/or authentication information associated with the transaction account. In such cases, the processing server 102 may request the check information from the respective issuing institution 106 using the account details provided by the consumer 104. For instance, the authentication information may be used to ensure that the consumer 104 is authorized for use of the transaction account, while the identifying information may be used to identify the transaction account being selected by the consumer 104. In these cases, the issuing institution 106 may provide the account number and check numbers for the traditional checks 108 issued on the selected transaction accounts to the processing server 102.
Once the processing server 102 has received check numbers and account numbers for the consumer's selected transaction accounts, the processing server 102 may create a series of multi-account checks 114 for the consumer 104. In an exemplary embodiment, data associated with the issuing of multi-account checks 114 to the consumer 104 may be stored in a blockchain. The blockchain may be managed via a blockchain network, which may be comprised of a plurality of nodes. Each node may be a computing system that is configured to perform functions related to the processing and management of the blockchain, including the generation of blockchain data values, verification of proposed blockchain transactions, verification of digital signatures, generation of new blocks, validation of new blocks, and maintenance of a copy of the blockchain. In some embodiments, the processing server 102 may be a node. In other embodiments, the processing server 102 may be in communication with a node using a suitable communication network and method.
The blockchain may be a distributed ledger that is comprised of at least a plurality of blocks. Each block may include at least a block header and one or more data values. Each block header may include at least a timestamp, a block reference value, and a data reference value. The timestamp may be a time at which the block header was generated, and may be represented using any suitable method (e.g., UNIX timestamp, DateTime, etc.). The block reference value may be a value that references an earlier block (e.g., based on timestamp) in the blockchain. In some embodiments, a block reference value in a block header may be a reference to the block header of the most recently added block prior to the respective block. In an exemplary embodiment, the block reference value may be a hash value generated via the hashing of the block header of the most recently added block. The data reference value may similarly be a reference to the one or more data values stored in the block that includes the block header. In an exemplary embodiment, the data reference value may be a hash value generated via the hashing of the one or more data values. For instance, the block reference value may be the root of a Merkle tree generated using the one or more data values.
The use of the block reference value and data reference value in each block header may result in the blockchain being immutable. Any attempted modification to a data value would require the generation of a new data reference value for that block, which would thereby require the subsequent block's block reference value to be newly generated, further requiring the generation of a new block reference value in every subsequent block. This would have to be performed and updated in every single node in the blockchain network prior to the generation and addition of a new block to the blockchain in order for the change to be made permanent. Computational and communication limitations may make such a modification exceedingly difficult, if not impossible, thus rendering the blockchain immutable.
Each blockchain data value may correspond to check data. A blockchain data value may include an account number and check number associated with a traditional check 108 or a multi-account check 114. In some cases, a single blockchain may be associated with a single consumer 104, where each blockchain data value included therein includes data for a check associated with the consumer 104. In other cases, blockchain data values in a blockchain may be associated with multiple consumers 104, where each blockchain data value may include information identifying the consumer 104. For instance, each consumer 104 that utilizes the processing server 102 may be provided with a unique identifier, such as a registration number, username, e-mail address, telephone number, etc., which may be included in all blockchain data values associated therewith.
When the consumer 104 registers with the processing server 102 for multi-account checks 114, a blockchain data value may be created and added to the blockchain for each of the transaction accounts that are to be associated with the multi-account check 114. The blockchain data value may include at least the account number and a plurality of check numbers associated with the respective traditional checks 108. In some cases, a single blockchain data value may be created for each check number. In other cases, a range of check numbers may be included in a single blockchain data value. A blockchain data value may be also be created and added to the blockchain that includes an account number and check number(s) for the multi-account checks 114. The account number associated with the multi-account checks 114 may be unique to the multi-account checks 114. In some cases, the account number may be based on the account number for one or more of the associated transaction accounts. In other cases, the account number may be random or pseudo-random.
The processing server 102 (e.g., or other device operating on behalf of or using instructions provided by the processing server 102) may print a plurality of physical checks, where each physical check is printed with the account number and one of the check numbers for the multi-account checks 114. In some cases, each multi-account check 114 may have a routing number printed thereon, where the routing number is associated with the processing server 102 such that payment transactions that are to be funded using the multi-account check 114 may be routed to the processing server 102 for processing. The multi-account checks 114 may be distributed to the consumer 104 using a suitable distribution method as will be apparent to persons having skill in the relevant art.
The consumer 104 may receive the multi-account checks 114 and may then proceed to use them when conducting electronic payment transactions. To use a multi-account check 114, the consumer 104 may present a multi-account check 114 to a merchant system 110 to fund a payment transaction in the same manner as the consumer 104 would use for a traditional check 108. The merchant system 110 may read the account number, routing number, and check number from the multi-account check 114 using a suitable method, such as the reading of magnetic ink printed on the multi-account check 114. The merchant system 110 may include the account number, routing number, and check number in transaction data that is submitted to the payment network 112 for processing of the electronic payment transaction.
In some embodiments, the merchant system 110 may submit the transaction data directly to the payment network 112 using payment rails associated therewith. In other embodiments, the merchant system 110 may submit the transaction data to an intermediate entity, such as an acquiring institution or a gateway processor. The transaction data may be included in a transaction message that is submitted to the payment network 112 via payment rails associated therewith. The transaction message may be a specially formatted data message that is formatted according to one or more standards governing the interchange of financial transaction messages, such as the International Organization of Standardization's ISO 8583 or ISO 20022 standards. In some cases, the merchant system 110 may generate the transaction message. In other cases, the merchant system 110 may forward the transaction data to an intermediate entity, such as an acquiring institution, which may generate the transaction message that includes the transaction data and forward the transaction message to the payment network 112.
The transaction message may include a message type indicator indicating a type of the transaction message, such as an authorization request or authorization response, as may be dictated via the applicable standards. The transaction message may also include a plurality of data elements, where each data element is configured to store transaction data, which may be specified by the applicable standards. The transaction data stored in the data elements of the transaction message may include at least the account number, routing number, and check number for the multi-account check 114 (e.g., which may be stored in a single data element or across multiple data elements), as well as any other data used in the processing of the payment transaction, such as a transaction amount, transaction time, transaction date, currency type, transaction type, merchant identifier, merchant category code, product data, issuer data, acquirer data, loyalty data, reward data, offer data, etc.
The payment network 112 may receive the transaction message and identify the routing number stored therein. The payment network 112 may then route the transaction message to the appropriate entity based on the routing number. For payment transactions where a multi-account check 114 is used, the transaction message may be routed to the processing server 102 and transmitted thereto by the payment network 112 using any suitable communication network and method, such as via the payment rails associated with the payment network 112. The processing server 102 may thus receive the transaction message for the payment transaction, which may be an authorization request.
The processing server 102 may receive the authorization request and, through the account number included therein, identify the transaction accounts associated with the multi-account check 114 used in the transaction. For example, the processing server 102 may identify the blockchain data value corresponding to the multi-account check 114 presented in the transaction based on the account number and check number, and may identify corresponding blockchain data values that include account numbers and routing numbers for the respective traditional checks 108. The processing server 102 may then initiate additional transactions to facilitate funding of the multi-account check 114 payment transaction via the underlying transaction accounts.
In some embodiments, the underlying transaction accounts may be used to fund the multi-account check 114 payment transaction, also referred to herein as the “main” or “initial” payment transaction, via standard electronic payment transactions. In such embodiments, the processing server 102 may generate an authorization request for a new payment transaction, also referred to herein as a “sub,” “subsequent,” “secondary,” or “alternate” payment transaction, for each of the transaction accounts that are tied to the multi-account check 114. The authorization request may include the account number and any other account details for the respective transaction account (e.g., the check number for the respective traditional check 108). In some instances, the authorization requests for the secondary payment transactions may include transaction data from the main authorization request. The transaction amount included in each secondary payment transaction may be based on the transaction amount included in the main payment transaction. In some cases, the transaction amount from the main payment transaction may be divided equally among the secondary payment transactions. In other cases, the portion of the main transaction amount paid using the transaction accounts may be set by the consumer 104, such as during the creation of the multi-account checks 114. For example, the consumer may specify that one transaction account pays for 40% of the main transaction while two other transaction accounts each pay for 30% of the main transaction.
Once the authorization requests are generated, the processing server 102 may initiate processing of the secondary payment transactions. In some embodiments, the processing server 102 may submit the authorization requests to the payment network 112 using payment rails associated therewith for processing using traditional methods or systems. In other embodiments, the processing server 102 may operate as a payment network with respect to the secondary payment transactions, such as by forwarding the authorization requests to the corresponding issuing institutions 106 for approval or denial. Processing of the secondary payment transactions may result in the processing server 102 receiving authorization responses for each of the secondary payment transactions, where each authorization response may include a data element configured to store a response code that indicates if the payment transaction is approved or denied. If all of the secondary payment transactions are approved, the main payment transaction may be approved. Approval of the main payment transaction may result in the issuing institutions 106 debiting the transaction accounts accordingly, and the processing server 102 generating an authorization response for the main payment transaction that is returned to the processing server 102 that includes a data element configured to store a response code indicating approval of the payment transaction. The authorization response may be submitted to the payment network 112, which may forward the approval to the merchant system 110, which may then finalize the payment transaction with the consumer 104, such as by furnishing transacted-for goods or services to the consumer 104.
In instances where one or more of the secondary payment transactions may be denied, the main payment transaction may also be denied. In such an instance, the processing server 102 may generate an authorization response that includes a response code indicating decline of the payment transaction, which may be submitted to the payment network 112 and processed accordingly. In these cases, the processing server 102 may inform the issuing institution 106 for each secondary payment transaction was approved to indicate that the secondary payment transaction should be reversed or otherwise not processed.
In some embodiments, the secondary payment transactions may be blockchain transactions. In such embodiments, the transaction accounts registered by the consumer 104 may be blockchain wallets configured for use in conducting blockchain transactions. In these cases, traditional checks 108 may be replaced by blockchain wallets, or blockchain wallets may be associated with a transaction account for which traditional checks 108 are issued to the consumer 104. For example, an issuing institution 106 may issue traditional checks 108 to the consumer 104 for a transaction account but also accommodate blockchain transactions.
A blockchain wallet may be associated with a blockchain network that is used to transmit and receive blockchain currency in electronic payment transactions conducted via the blockchain network. A blockchain wallet may be an application program that is executed by a computing device possessed by the consumer 104. A blockchain wallet may include a private key of a cryptographic key pair that is used to generate digital signatures that serve as authorization by the consumer 104 for a blockchain transaction, where the digital signature can be verified by the blockchain network using the public key of the cryptographic key pair. In some cases, the term “blockchain wallet” may refer specifically to the private key. In some embodiments, an issuing institution 106 may store the consumer's private key. In other embodiments, the private key may be stored on the computing device of the consumer 104. The computing device may be any type of device suitable for performing the functions discussed herein, such as a desktop computer, laptop computer, tablet computer, notebook computer, cellular phone, smart phone, smart watch, smart television, wearable computing device, implantable computing device, etc.
Blockchain transactions may be processed and stored on a blockchain dedicated thereto, which may be different from the blockchain used to store data for multi-account checks. In such blockchains, each blockchain data value may correspond to a blockchain transaction. A blockchain transaction may consist of at least: a digital signature of the sender of currency (e.g., the consumer 104) that is generated using the sender's private key, a blockchain address of the recipient of currency (e.g., the merchant system 110) generated using the recipient's public key, and a blockchain currency amount that is transferred. In some blockchain transactions, the transaction may also include one or more blockchain addresses of the sender where blockchain currency is currently stored (e.g., where the digital signature proves their access to such currency), as well as an address generated using the sender's public key for any change that is to be retained by the sender. In some cases, a blockchain transaction may also include the sender's public key, for use by any entity in validating the transaction. For the processing of a blockchain transaction, such data may be provided to a node in the blockchain network, either by the sender (e.g., via the computing device) or the recipient (e.g., by the merchant system 110). The node may verify the digital signature and the sender's access to the funds, and then include the blockchain transaction in a new block. The new block may be validated by other nodes in the blockchain network before being added to the blockchain and distributed to all of the nodes in the blockchain network.
In a standard blockchain transaction, the consumer 104 may thus generate a digital signature using the computing device of the consumer 104 using the private key thereof. The merchant system 110 may generate a blockchain address using its public key, which may be provided to the computing device. In some cases, the merchant system 110 may provide the computing device with its public key, where the computing device may generate the blockchain address. The computing device may then submit the required information to a node in the blockchain network for processing. In some instances, the node may return a blockchain transaction identifier to the computing device, which may be a value that is unique to that blockchain transaction for identification thereof. In such traditional transactions, the merchant system 110 is required to generate blockchain address or distribute its public key, and, in some cases, may be required to submit the transaction data directly to blockchain networks.
In the system 100, the processing server 102 may be configured to perform the secondary payment transactions as blockchain transactions. In such embodiments, the processing server 102 may identify recipient addresses for the merchant system 110 for each blockchain transaction, which may be included in the authorization request, provided directly by the merchant system 110, or identified using a public key associated with the merchant system 110 that may be included in the authorization request or already stored by the processing server 102, such as from an earlier transaction or during a registration process by the merchant system 110. The processing server 102 may also generate or otherwise identify a digital signature for each of the blockchain wallets associated with the multi-account check 114, as may be identified using the blockchain data values identified through the multi-account check 114 account number. In some cases, the blockchain data values may include digital signatures or the private keys used to generate digital signatures. In other cases, the blockchain data values may include data used to communicate with the issuing institutions 106 or consumer 104 (e.g., via one or more computing devices) to request digital signatures.
The processing server 102 may then submit blockchain transactions for each secondary payment transaction to a node in a blockchain network for processing. Each blockchain transaction may include at least a digital signature to prove access to sufficient blockchain currency by the consumer 104 and a recipient address for the merchant system 110, as well as a blockchain currency amount. The blockchain currency amount may be based on the transaction amount of the main payment transaction, such as discussed above. The blockchain transactions may be verified and added to the blockchain. If verification of any blockchain transaction is unsuccessful, the processing server 102 may deny the main payment transaction, as discussed above. If all of the secondary blockchain transactions are successful, then the processing server 102 may approve the main payment transaction, as also discussed above.

Process for Processing of Multi-Account Checks
In step 302, the receiving device 202 of the processing server 102 may receive an authorization request for a payment transaction from the payment network 112. The authorization request may include a plurality of data elements including data elements configured to store at least a transaction amount and an account number and check number for a multi-account check 114. In step 304, the processing server 102 may identify a blockchain associated with the consumer 104 involved in the transaction based on the account number or other data included in the authorization request. The consumer blockchain may be stored in the processing server 102 (e.g., in the memory 226 or an account profile 208 associated with the consumer 104) or retrieved from a node in a blockchain network.
In step 306, the processing server 102 may identify a type of transaction to be used for the secondary payment transactions. In some cases, the processing server 102 may identify the type based on data included in the authorization request, such as may be specified by the consumer 104 or merchant system 110. In other cases, the type may be specified in the account profile 208 or the consumer 104 or the consumer blockchain. For instance, the blockchain data values stored in the consumer blockchain may include blockchain wallet data or traditional check 108 data, which may be used for the identification.
If, in step 306, the processing server 102 determines that the secondary transactions should be blockchain transactions, then, in step 308, the processing server 102 may identify private keys for the underlying blockchain wallets associated with the multi-account check 114. In some cases, the private keys may be stored in the blockchain data values included in the consumer blockchain. In other cases, the private keys may be stored in the account profile 208 and may be identified using data included in the blockchain data values of the consumer blockchain. In step 310, the generation module 220 of the processing server 102 may generate a digital signature using each of the identified private keys. In step 312, the transmitting device 224 of the processing server 102 may submit a blockchain transaction for each blockchain wallet to a node in the blockchain network, where the blockchain transaction includes a digital signature, recipient address, and currency amount. The receiving device 202 of the processing server 102 may receive confirmation of the blockchain transactions and then, in step 314, the processing server 102 may (e.g., via the generation module 220) generate an authorization response for the main payment transaction and transmit (e.g., via the transmitting device 224) the authorization response to the payment network 112.
If, in step 306, the processing server 102 determines that the secondary transactions are traditional (e.g., fiat) payment transactions, then, in step 316, the processing server 102 may identify the traditional checks 108 that are associated with the multi-account check 114 using the blockchain data values in the consumer blockchain. In step 318, the generation module 220 of the processing server 102 may generate an authorization request for a secondary payment transaction for each of the traditional checks 108, where each authorization request may include the account details for the respective traditional check 108 and a transaction amount based on the transaction amount in the main payment transaction. In step 320, the transmitting device 224 of the processing server 102 may forward the authorization requests to the associated issuing institutions 106.
In step 322, the receiving device 202 of the processing server 102 may receive authorization responses for each of the secondary payment transactions from the corresponding issuing institutions 106. In step 324, the processing server 102 may determine if all of the authorization responses indicate approval of the respective secondary payment transactions, as may be identified based on the response code stored in a corresponding data element in the authorization response. If at least one of the secondary payment transactions is declined, then, in step 326, the generation module 220 may generate an authorization response for the main payment transaction that includes a response code indicating decline of the payment transaction. If all of the secondary payment transactions are approved, then, in step 328, the generation module 220 may generate an authorization response for the main payment transaction that includes a response code indicating approval of the payment transaction. In step 330, the transmitting device 224 of the processing server 102 may electronically transmit the authorization response for the main payment transaction to the payment network 112.
