     As noted above, product awards in product awards accounts may be earned, redeemed, and/or gifted through the product awards management system.  FIG.  3    is a flowchart of an exemplary product awards earning process  300 , consistent with disclosed embodiments. In some embodiments, product awards earning process  300  may be carried out by a product awards management system, such as product awards management systems  102  and  200  described above. 
     As shown, product awards earning process  300  includes, at block  302 , maintaining a product awards account associated with a user. The product awards account may be directly associated with the user and/or may be associated with a payment device and/or computing device associated with the user. As described above in connection with  FIG.  2 B , the product awards account may include product awards for each of a plurality of product awards programs. 
     Product awards earning process  300  further includes, at block  304 , receiving an indication of a transaction conducted by the user using a payment device at a merchant. The product awards management system may receive the indication from, for example, the user, the payment device, the merchant, a computing device associated with the user, and/or a financial service provider. For example, the user may provide the indication to the product awards management system through, for example, a product awards application executed on a computing device, such as product awards application  122  described above. The user may, for instance, take a photograph of a receipt, display, or other evidence of the transaction and upload the photograph to the product awards management system using the product awards application. As another example, for a transaction authorized by the financial service provider, the merchant and/or the financial service provider may provide the indication to the product awards management system when the transaction is authorized. 
     At block  306 , product awards earning process  306  includes, based on at least one of the transaction, the payment device, and the merchant, determining product awards for at least one product awards program for the transaction. For example, the product awards may vary with an amount of the transaction and/or a time at which the transaction occurred. As another example, the at least one product awards program may include a “Payment Device” product awards program in which product awards may be earned on transactions made using the payment device according to the terms of the “Payment Device” product awards program. As still another example, the at least one product awards program may include a “Dining Awards” product awards program in which product awards may be earned on transactions made at the merchant (e.g., a restaurant) according to the terms of the “Dining Awards” product awards program. 
     In some embodiments, terms of a product awards program may specify that the product awards may be determined according to a predefined algorithm taking as an input one or more of the amount of the transaction, a time at which the transaction occurred, a payment device used in the transaction, and/or the merchant at which the transaction was made. In some embodiments, the predefined algorithm may vary among product awards programs. For example, an “Airline Awards” product awards program may specify one predefined algorithm to determine product awards for the “Airline Awards” product awards program, while a “Hotel Awards” product awards program may specify another predefined algorithm to determine product awards for the “Hotel Awards” product awards program. In some embodiments, product awards may be determined for more than one product awards program for the transaction. For example, product awards may be determined for a “Payment Device Awards” product awards program as well as for an “Airline Awards” product awards program. 
     Product awards earning process  306  further includes, at block  308 , updating the product awards account to reflect the product awards for the at least one product awards program. For example, where the product awards determined in block  308  included product awards for an “Airline Awards” product awards program and for a “Hotel Awards” product awards program, updating the product awards account may involve adding the product awards for the “Airline Awards” product awards program determined in block  308  to previously determined product awards for the “Airline Awards” product awards program and adding the product awards for the “Hotel Awards” product awards program determined in block  308  to previously determined product awards for the “Hotel Awards” product awards program. An example product awards earning process is further described in connection with  FIGS.  4  and  5 A- 5 B . 
       FIG.  4    illustrates another message flow  400  in an exemplary product awards earning process, consistent with disclosed embodiments.  FIGS.  5 A- 5 B  illustrate a product awards account  500  in an exemplary product awards earning process, consistent with disclosed embodiments. As shown in  FIG.  4   , the message flow  400  begins with message(s)  402 A through which a user conducts a transaction with a merchant. For example, a user may use a computing device and/or a payment device to make payment for an item of value offered by the merchant. 
     With message(s)  402 B, the merchant may seek authorization of the transaction from a financial service provider maintaining a financial services account associated with the user, and the financial service provider may authorize the transaction. Once the transaction has been authorized, the product awards management system may receive an indication of the transaction. The indication may indicate, for example, the user, the payment device and/or computing device used to conduct the transaction, the merchant, the financial service provider, the payment, and/or the item of value. 
     In some embodiments, the product awards management system may receive the indication from the user, as shown with message(s)  404 A. For example, the indication may take the form of a photograph or other data captured by the user using, for example, the computing device, and the indication may be provided to the product awards management system through, for example, a product awards application executed at the computing device. Alternatively or additionally, in some embodiments the product awards management system may receive the indication from the merchant, as shown with message(s)  404 B. For example, the merchant may provide the indication to the product awards management system after the transaction is authorized. Still alternatively or additionally, in some embodiments the product awards management system may receive the indication from the financial service provider, as shown with message(s)  404 C. For example, the financial service provider may provide the indication to the product awards management system after the transaction is authorized. The product awards management system may receive the indication in other manners as well. 
     The product awards management system  406  may update the product awards account for the user at  406 . As shown in  FIGS.  5 A- 5 B , updating the product awards account  500  may involve, for example, updating the product awards  504  for at least one product awards program  502  in the product awards account. As shown, the product awards programs  502  may include, for example, an “Airline Awards” product awards program, a “Hotel Awards” product awards program, and a “Payment Device” product awards program. 
     Prior to the update, for instance, as shown in  FIG.  5 A , the product awards account  500  may show product awards having a value of 112,000 for an “Airline Awards” product awards program, product awards having a value of 36,000 for a “Hotel Awards” product awards program, and product awards having a value of 15,280 for a “Payment Device Awards” product awards program. 
     By the transaction, the user may earn product awards for the “Hotel Awards” product awards program and the “Payment Device” product awards program. Accordingly, following the update, as shown in  FIG.  5 B , the product awards for the “Airline Awards” product awards program may be unchanged, as the underlying transaction does not qualify for product awards under the “Airline Awards” product awards program. The product awards for the “Hotel Awards” product awards program and for the “Payment Device Awards” product awards program, by contrast, may be updated. For instance, as shown, the product awards for the “Hotel Awards” product awards may be increased from the value of 36,000 to a value of 37,500, while the product awards for the “Payment Device Awards” may be increased from the value of 15,280 to a value of 16,000. Other updates are possible as well. In some embodiments, the product awards management system may notify the user, computing device, merchant, and/or financial service provider of the update to the product awards account. 
       FIG.  6    is a flowchart of an exemplary product awards redemption process  600 , consistent with disclosed embodiments. In some embodiments, product awards redemption process  600  may be carried out by a product awards management system, such as product awards management systems  102  and  200  described above. 
     As shown, product awards redemption process  600  includes, at block  602 , maintaining a product awards account associated with a user. The product awards account may include product awards for each of a plurality of product awards programs, as described above. 
     Product awards redemption process  600  continues at block  604  with receiving a request for a redemption transaction at a merchant. The redemption transaction may be any transaction in which product awards, alone or in combination with currency, are redeemed for an item of value. For example, a redemption transaction may involve a user redeeming product awards, alone or in combination with currency, to purchase an item of value from a merchant. 
     The request for the redemption transaction may be received from, for example, the user. For example, the user may request, through a product awards application on a computing device, to redeem product awards for an item of value from a merchant. Alternatively or additionally, the request for the redemption transaction may be received from, for example, a merchant. For example, the merchant may offer to the user to redeem product awards for an item of value from the merchant, and the user may accept the offer. In response to the user’s acceptance, the merchant may provide the request for the redemption transaction to the product awards management system. 
     At block  606 , the product awards redemption process  600  includes, based on at least one of the transaction and the merchant, providing a redemption option. The redemption option may indicate redeemable product awards from at least one product awards program in the plurality of product awards programs. Redeemable product awards may be deducted from a product awards program in exchange for an item of value from the merchant. 
     For example, the redemption option may indicate that the user may redeem a value of product awards from a “Dining Awards” product awards program to purchase the item of value from the merchant. As another example, the redemption option may indicate that the user may redeem a value of product awards from a “Dining Awards” product awards program in combination with a value of product awards from an “Airline Awards” product awards program to purchase the item of value from the merchant. As still another example, the redemption option may indicate that the user may redeem a value of product awards from a “Payment Device” product awards program in combination with a value of currency to purchase the item of value from the merchant. In some embodiments, the redemption option may include more than one option. For example, the redemption option may include each of the examples described above. 
     The redemption option may be provided to the user (e.g., through the product awards application on the computing device) and/or may be provided to the merchant. Where the redemption option is provided to the merchant, the merchant may present the redemption option to the user. For example, in a physical retail environment, the merchant may present the redemption option to the user through a point-of-sale terminal. As another example, in an online retail environment, the merchant may present the redemption option the user through a pop-up notification in a web browser application. 
     The product awards redemption process  600  includes, at block  608 , receiving a selection of the redemption option. The selection may be received from, for example, the user (e.g., through the product awards application on the computing device). Alternatively or additionally, the merchant may receive the selection from the user, and the merchant provide the selection to the product awards management system. For example, in a physical retail environment, the merchant may receive the selection through a point-of-sale terminal. As another example, in an online retail environment, the merchant may receive the selection through a pop-up notification in a web browser application. Other examples are possible as well. 
     At block  610 , the product awards redemption process  600  includes, in response to receiving the selection, redeeming the redeemable product awards to conduct the redemption transaction and updating the at least one product awards program to reflect the redemption transaction. Redeeming the redeemable product awards to conduct the redemption transaction may involve, for example, transferring the redeemable product awards from the at least one product awards program to the merchant and transferring the merchant’s item of value to the user. The redeemable product awards may be redeemed in other manners as well. Updating the at least one product awards program to reflect the redemption transaction may involve, for example, deducting the redeemable product awards from the at least one product awards program. 
     An example product awards redemption process is further described in connection with  FIGS.  7  and  8 A- 8 D .  FIG.  7    illustrates message flow in an exemplary product awards redemption process, consistent with disclosed embodiments.  FIGS.  8 A- 8 D  illustrate a product awards application and a product awards account in an exemplary product awards redemption process, consistent with disclosed embodiments. As shown in  FIG.  7   , the message flow  700  begins with message(s)  702 , with which a user requests a redemption transaction from product awards management system. In some embodiments, the user may request the redemption transaction through a product awards application  802  executed on a computing device  800 , as shown in  FIG.  8 A . For example, the user may select a selection  804  to “Redeem Your Awards!” in the product awards application  802 . The computing device  800  may provide the request to the product awards management system. 
     In response to receiving the request, the product awards management system provides a redemption option to the computing device with message(s)  704 . An example redemption option  806  is shown in  FIG.  8 B . The redemption option  806  may specify product awards from one or more product awards programs associated with the user that may be redeemed to purchase the item of value. In some embodiments, the product awards application  802  may permit a user to vary product awards from one or more product awards programs to view various redemption options. For example, a user may increase product awards from one product awards program while decreasing product awards from another. As another example, a user may increase product awards from a product awards program to decrease a payment price. Other examples are possible as well. The user may select the redemption option through the product awards application, as shown by message(s)  706 . 
     In some embodiments, in response to receiving the selection of the redemption option, the product awards management system may provide to the computing device a redemption certificate with message(s)  708 . The redemption certificate may take the form of, for example, a bar code, two-dimensional bar code (e.g., QR code), or alphanumeric code for display in the product awards application. Other redemption certificates are possible as well. The computing device may, with message(s)  710 , provide the redemption certificate to the merchant to conduct the redemption transaction. 
     With message(s)  712 , the merchant may conduct the redemption transaction with the product awards management system. In embodiments where the redemption option involved a combination of redeemable product awards and currency, the merchant may additionally conduct a transaction with the financial service provider with message(s)  714  for the amount of currency indicated in the redemption option. In these embodiments, the currency may be provided using, for example, a payment device and/or cash. 
     The product awards management system may update the product awards account for the user at  716 . As shown in  FIGS.  8 C- 8 D , updating the product awards account  808  may involve, for example, updating the product awards  812  for at least one product awards program  812  in the product awards account. As shown, the product awards programs  812  may include, for example, an “Airline Awards” product awards program, a “Hotel Awards” product awards program, and a “Payment Device” product awards program. Other product awards programs  812  are possible as well. 
     Prior to the update, for instance, as shown in  FIG.  8 C , the product awards account  808  may show product awards having a value of 80,000 for an “Airline Awards” product awards program, product awards having a value of 118,000 for a “Hotel Awards” product awards program, and product awards having a value of 10,500 for a “Payment Device Awards” product awards program. Following the update, as shown in  FIG.  8 D , the product awards for the “Payment Device Awards” product awards program may be unchanged. This may be because, for example, the underlying transaction does not qualify for product awards under the “Payment Device Awards” product awards program. The product awards for the “Airline Awards” product awards program and for the “Hotel Awards” product awards program, by contrast, may be updated. For instance, as shown, the product awards for the “Airline Awards” product awards may be decreased from the value of 80,000 to a value of 76,000, while the product awards for the “Hotel Awards” may be decreased from the value of 10,500 to a value of 9,500 according to the redemption option. Other updates are possible as well. In some embodiments, the product awards management system may notify the user, computing device, merchant, and/or financial service provider of the update to the product awards accounts. 
       FIG.  9    is a flowchart of an exemplary product awards gifting process  900 , consistent with disclosed embodiments. In some embodiments, product awards gifting process  900  may be carried out by a product awards management system, such as product awards management systems  102  and  200  described above. 
     Product awards gifting process  900  includes, at block  902 , maintaining a product awards account associated with a user. The product awards account may include product awards for a plurality of product awards programs, as described above. 
     The product awards gifting process  900  further includes, at block  904 , receiving a request for a gift transaction. A gift transaction may be any transaction in which product awards (and/or an item of value for which product awards are exchanged through a redemption transaction) are transferred to another product awards account. The request may be received from, for example, a computing device. 
     At block  906 , the product awards gifting process  900  includes providing a gift option. The gift option may be provided to the user through, for example, a product awards application executed at the computing device. The gift option may indicate giftable product awards from at least one product awards program in the plurality of product awards programs in the user’s product awards account. The gift option may include more than one option of giftable product awards. The gift option may further indicate a recipient of the gift. The recipient may be identified by, for example, a product awards account, a telephone number, an email address, and/or a mailing address. The recipient may be identified in other manners as well. 
     At block  908 , the product awards gifting process  900  includes receiving a selection of the gift option. The selection may be received from the user through, for example, the product awards application executed at the computing device. The product awards gifting process  900  may further include, at block  910 , in response to receiving the selection, gifting the giftable product awards to conduct the gift transaction and updating the at least one product awards program in the user’s product awards account to reflect the gift transaction. Gifting the giftable product awards to conduct the gift transaction may involve, for example, deducting the giftable product awards from the user’s product awards account and providing the giftable product awards to the identified recipient. Providing the giftable product awards to the identified recipient may involve, for example, adding the giftable product awards to a product awards account associated with the recipient or texting, emailing, and/or mailing the giftable product awards (e.g., in the form of gift certificate) to the recipient. An example product awards gifting process is further described in connection with  FIGS.  10  and  11 A- 11 D . 
       FIG.  10    illustrates message flow in an exemplary product awards gifting process, consistent with disclosed embodiments.  FIGS.  11 A- 11 D  illustrate a product awards application and a product awards account in an exemplary product awards gifting process, consistent with disclosed embodiments. As shown in  FIG.  10   , the message flow  1000  begins with message(s)  1002 , with which the users provides to the product awards management system a requests for gift transaction. The user may provide the request through, for example, a product awards application  1102  executed at a computing device  1100 , as shown in  FIG.  11 A . For example, the user may select a selection  1104  to “Gift Your Awards!” in the product awards application  1102 . The computing device  1100  may provide the request to the product awards management system. 
     With message(s)  1004 , the product awards management system provides a gift option to the user. The gift option may indicate giftable product awards from at least one product awards program associated with the first computing device. An example gift option  1106  is shown in  FIG.  11 B . The gift option  1106  may specify product awards from one or more product awards accounts associated with the user that may be redeemed to purchase the item of value. In some embodiments, the product awards application  1102  may permit a user to vary product awards from one or more product awards programs to view various gift options. The gift may be a gift of product awards or of currency. For example, a user may increase product awards from one product awards program while decreasing product awards from another. As another example, a user may increase product awards from one or more product awards programs to increase a currency value of the gift. As still another example, a user may gift currency in combination with product awards from one or more product awards programs. Other examples are possible as well. The user may select the gift option through the product awards application, as shown by message(s)  1006 . 
     With message(s)  1008 , the product awards management system may conduct the gift transaction, providing the gift to the recipient. The product awards management system may update the product awards account associated with the user at  1010 . Updating the product awards account may involve, for example, deducting the giftable product awards from the user’s account. In some embodiments, such as those where the gift is in the form of product awards, the product awards management system may additionally update a product awards account associated with the recipient by adding the giftable product awards. 
     As shown in  FIGS.  11 C- 11 D , for example, updating the product awards account  1100  associated with the user may involve, for example, updating the product awards  1112  for at least one product awards program  1110  in the product awards account. As shown, the product awards programs  1110  may include, for example, an “Airline Awards” product awards program, a “Hotel Awards” product awards program, and a “Payment Device” product awards program. Other product awards programs  1110  are possible as well. 
     Prior to the update, for instance, as shown in  FIG.  11 C , the product awards account  1108  may show product awards having a value of 25,000 for an “Airline Awards” product awards program, product awards having a value of 6,000 for a “Hotel Awards” product awards program, and product awards having a value of 100,000 for a “Payment Device Awards” product awards program. Following the update, as shown in  FIG.  11 D , the product awards for the “Hotel Awards” and “Payment Device Awards” product awards program may be unchanged. This may be because, for example, the gift option selected by the user did not include any product awards in these product awards programs. The product awards for the “Airline Awards” product awards program, by contrast, may be updated. For instance, as shown, the product awards for the “Airline Awards” product awards may be decreased from the value of 25,000 to a value of 15,000 according to the gift option. 
     While not shown, in some embodiments a product awards account associated with the recipient may be updated as well. For example, where the gift is in the form of product awards, the product awards management system may additionally update a product awards account associated with the recipient by adding the giftable product awards. For instance, product awards in an “Airline Awards” product awards program may be increased by a value of 10,000. As another example, the product awards in an “Airline Awards” program may be increased by a different value and/or product awards in another product awards program may be increased by any value. Other updates are possible as well. In some embodiments, the product awards management system may notify the user, first computing device, second computing device, and/or a user associated with the second computing device of the update to the product awards accounts. 
     The above description focused on product awards accounts in which product awards took arbitrary values, such as “points” or “miles.” In some embodiments, however, product awards may take a non-arbitrary value, such as a unit whose operation is regulated according to one or more encryption techniques. The encryption techniques may be, for example, encryption techniques associated with a blockchain. The encryption technique(s) may include, for example, hashing techniques, such as a cryptographic hash. In some embodiments, the units may correspond to a currency and/or a cryptocurrency, such as bitcoin or Ven. 
     In some embodiments, operation of the units may include, for example, generation of the units, redemption of the units, and/or exchange of the units. In some embodiments, generation, redemption, and/or exchange of the units may be governed by a single encryption technique and/or by multiple encryption techniques, and the encryption technique(s) for each of generation, redemption, and/or exchange may be the same or different. 
     Operation of the units may be maintained in the blockchain, which may include a number of transactions involving the units. For example, each transaction involving the units may be entered into the blockchain as encrypted data associated with the transaction. The encrypted data may be encrypted according to the encryption technique(s). 
     The encryption techniques may serve to regulate generation of the units. Generation of units may be regulated by the encryption technique(s) through, for example, the use of mining. When a new transaction is encrypted, for example, a cryptographic hash of the transaction may be generated. Using the blockchain and the new transaction, an entity may determine (“mine”) a value that, when encrypted alongside the transactions in the blockchain and the new transaction, creates a cryptographic hash having certain properties (e.g., a cryptographic hash beginning with a certain number of zeroes). The value may be difficult to discern. Accordingly, the first miner to determine the value may be rewarded with newly generated units. Encrypted data associated with the transaction generating the newly generated units may be entered into the blockchain. Because the encryption techniques are difficult to discern, generation of units may be a slow, steady process. The encryption techniques may further serve to prevent tampering with transactions entered into the blockchain. Because the encryption techniques are difficult to discern, a single entity cannot cause widespread tampering. The encryption techniques 
       FIG.  12    is a block diagram of an exemplary system  1200  configured to regulate generation of units according to at least one encryption technique associated with a blockchain, consistent with disclosed embodiments.

The network of participants  1402  may be communicatively coupled to one another, and each participant  1404  in the network  1402  may maintain a copy of the digital ledger of transactions. 
     Each participant  1404  may be configured to enter transactions involving units into the distributed digital ledger. In some embodiments, the units may correspond to a currency and/or a cryptocurrency, such as bitcoin or Ven. The blockchain  1400  may be associated with at least one encryption technique. The encryption technique(s) may include, for example, hashing techniques, such as a cryptographic hash. 
     Entry of transactions may be secured by the encryption technique(s). Additionally, each transaction may be traceable through the blockchain  1400 . When a participant  1404  proposes to enter a transaction into the digital ledger, each remaining participant  1404  may verify the proposed transaction with reference to the digital ledger maintained by the remaining participant  1404 . If a sufficient number of the remaining participants agree, the proposed transaction may be entered into each digital ledger, thereby forming a new block added to blockchain  1400 . 
       FIG.  15    is a flowchart of an exemplary conversion process  1500 , consistent with disclosed embodiments. In some embodiments, conversion process  1500  may be carried out by a product awards management system, such as product awards management systems  1202  and  1300  described above. 
     As shown, conversion process  1500  includes, at block  1502 , maintaining an account associated with a user. The account may include product awards for each of a plurality of product awards programs. For example, referring back to  FIG.  12   , product awards management system  1202  may maintain an account for user  108 . The account may include, for example, product awards for a product awards program associated with, for example, merchant  1210  and product awards for a product awards program associated with, for example, financial service provider  1212 . For instance, the accounts may include product awards for an “Airline Awards” product awards program and/or product awards for a “Hotel Awards” product awards program. 
     Conversion process  1500  further includes, at block  1504 , receiving transaction information describing a transaction. The transaction information may include, for example, an indication of a transaction conducted by the user using a payment device at a merchant. For example, referring back to  FIG.  12   , product awards management system  1202  may receive an indication of a transaction conducted by user  1208  using payment device  1206  at merchant  1210 . The product awards management system may receive the transaction information from, for example, the user, the payment device, the merchant, a computing device associated with the user, and/or a financial service provider. For example, the user may provide the transaction information to the product awards management system through, for example, an application executed on a computing device, such as application  1224  described above. The user may, for instance, take a photograph of a receipt, display, or other evidence of the transaction and upload the photograph to the product awards management system using the application. As another example, for a transaction authorized by the financial service provider, the merchant and/or the financial service provider may provide the transaction information to the product awards management system when the transaction is authorized. 
     At block  1506 , conversion process  1500  includes, based on the transaction information, determining product awards for at least one product awards program for the transaction. For example, the product awards may be determined based on at least one of the transaction, the payment device, and the merchant. The product awards may be determined in any of the manners described above for block  306  in connection with  FIG.  3   . 
     At block  1508 , conversion process  1500  further includes, using the blockchain, determining a real-time conversion rate for the transaction. The real-time conversion rate may be regulated by the at least one encryption technique. For example, the real-time conversion rate may reflect a real-time valuation of the product awards in the at least one product awards program as evidenced by transactions, entered as encrypted data, in the blockchain. The real-time conversion rate may be product awards program specific, such that product awards in one product awards program may have a different real-time conversion rate than product awards in another product awards program. The real-time conversion rate may also be time specific, such that the real-time conversion rate for product awards in a product awards program at one time may be different than at another time. 
     The real-time conversion rate may reflect, for example, a supply and/or demand of the units and/or a supply and/or demand of the product awards. The conversion rate may be determined based on, for example, some or all of the transactions included in the blockchain, such as some or all transactions involving the product awards and/or the units and/or some or all transactions entered in the blockchain within a period of time. For instance, the real-time conversion rate may reflect transactions in the blockchain in which the product awards were previously exchanged for units, currency, and/or for product awards in other product awards programs. Alternatively, the conversion rate may be a fixed conversion rate. 
     At block  1510 , conversion process  1500  further includes, based on the real-time conversion rate, converting the product awards to units. Where the at least one product awards program includes more than one product awards program, the product awards may be converted according to the real-time conversion rate for each product awards’ product awards program. 
     Conversion process  1500  further includes, at block  1512 , updating the account to reflect the units for the at least one product awards program. For example, the product awards management system  1502  may update the user’s account to add the units determined in block  1510 . An example conversion process is further described in connection with  FIGS.  16  and  17 A- 17 B . 
     Conversion process  1500  further includes, at block  1514 , entering into the blockchain encrypted data associated with the transaction. The encrypted data may be encrypted according to the at least one encryption technique. The encrypted data associated with the transaction may indicate, for example, the computing device, the product awards, the product awards program, and/or the units. The transaction may take any of the forms described above in connection with  FIGS.  14 A- 14 B . 
       FIG.  16    illustrates message flow  1600  in an exemplary earning process, consistent with disclosed embodiments.  FIG.  17 A- 17    illustrate an account  1700  in an exemplary earning process, consistent with disclosed embodiments. As shown in  FIG.  16   , the message flow  1600  begins with message(s)  1602 A through which a user conducts a transaction with a merchant. For example, a user may use a computing device and/or a payment device to make payment for an item of value offered by the merchant. 
     With message(s)  1602 B, the merchant may seek authorization of the transaction from a financial service provider maintaining a financial services account associated with the user, and the financial service provider may authorize the transaction. Once the transaction has been authorized, the product awards management system may receive an indication of the transaction. The indication may indicate, for example, the user, the payment device and/or computing device used to conduct the transaction, the merchant, the financial service provider, the payment, and/or the item of value. 
     In some embodiments, the product awards management system may receive the indication from the user, as shown with message(s)  1604 A. For example, the indication may take the form of a photograph or other data captured by the user using, for example, the computing device, and the indication may be provided to the product awards management system through, for example, an application executed at the computing device. Alternatively or additionally, in some embodiments the product awards management system may receive the indication from the merchant, as shown with message(s)  1604 B. For example, the merchant may provide the indication to the product awards management system after the transaction is authorized. Still alternatively or additionally, in some embodiments the product awards management system may receive the indication from the financial service provider, as shown with message(s)  1604 C. For example, the financial service provider may provide the indication to the product awards management system after the transaction is authorized. The product awards management system may receive the indication in other manners as well. 
     Following message(s)  1604 A,  1604 B, and/or  1604 C, the product awards management system may update the account for the user to reflect the units ( 1606 ). As shown in  FIG.  17 A , updating the account  1700  may involve, for example, updating the product awards  1704  for at least one product awards program  1702  in the account. As shown, the product awards programs  1702  may include, for example, an “Airline Awards” product awards program, a “Hotel Awards” product awards program, and a “Payment Device Awards” product awards program. 
     Prior to the update, for instance, as shown in  FIG.  17 A , the account  1700  may show product awards having a value of 112,000 for an “Airline Awards” product awards program, product awards having a value of 36,000 for a “Hotel Awards” product awards program, and product awards having a value of 15,280 for a “Payment Device Awards” product awards program. Following the update, as shown in  FIG.  17 B , the product awards for the “Airline Awards” product awards program may be unchanged. This may be because, for example, the underlying transaction does not qualify for product awards under the “Airline Awards” product awards program. The product awards for the “Hotel Awards” product awards program and for the “Payment Device Awards” product awards program, by contrast, may be updated. For instance, as shown, to the “Hotel Awards” product awards may be added units  1706  having a value of 38.50, while to the “Payment Device Awards” product awards program may be added units  1706  having a value of 88.02. 
     In some embodiments, the account  1700  may include both product awards  1704  and units  1706 . A user may, for example, be given the option of converting some or all earned product awards to units, either at the time the product awards are earned or at a later time, according to a real-time conversion rate, as described above. Alternatively, in some embodiments the account  1700  may include only units  1706 , and all product awards  1704  in the account  1700  may be converted to units  1706 . In some embodiments, the product awards management system may notify the user, computing device, merchant, and/or financial service provider of the update to the account. 
     In some embodiments, in addition to updating the account associated with the user, the product awards management system may update the blockchain to reflect the transaction. For example, the product awards management system may enter the transaction into the blockchain. The transaction may specify, for instance, the user, the merchant, the payment, and/or the item of value, as well as a date and/or time for the transaction. Alternatively or additionally, the product awards management system may update the blockchain to reflect the earned units. For example, for units in a product awards program associated with a product awards issuer (e.g., a merchant and/or a financial service provider), the product awards management system may enter a transaction into the blockchain specifying the user, the product awards issuer, the units, and/or a date and/or time for the transaction. The transaction may indicate, for instance, that the units were transferred from the product awards issuer to the user. 
       FIG.  18    is a flowchart of an exemplary redemption process, consistent with disclosed embodiments. In some embodiments, redemption process  1800  may be carried out by a product awards management system, such as product awards management systems  1202  and  1300  described above. The product awards management system may be configure for regulating generation of units according to at least one encryption technique associated with a blockchain, as described above. 
     As shown, redemption process  1800  includes, at block  1802 , maintaining an account associated with a user. The account may include units for each of a plurality of product awards programs. For example, referring back to  FIG.  12   , product awards management system  1202  may maintain an account for user  1208 . The account may include units for a product awards program associated with, for example, merchant  1210  and units for a product awards program associated with, for example, financial service provider  1212 . For instance, the account may include units for an “Airline Awards” product awards program and/or product awards for a “Hotel Awards” product awards program. Other product awards programs are possible as well. 
     Redemption process  1800  continues at block  1804  with receiving a request for a redemption transaction at a merchant. The redemption transaction may be any transaction in which units, alone or in combination with product awards and/or currency, are redeemed for an item of value. For example, a redemption transaction may involve a user redeeming units, alone or in combination with product awards and/or currency, to purchase an item of value from a merchant. 
     The request for the redemption transaction may be received from, for example, the user. For example, the user may request, through an application on a computing device, to redeem units for an item of value from a merchant. Alternatively or additionally, the request for the redemption transaction may be received from, for example, a merchant. For example, the merchant may offer to the user to redeem units for an item of value from the merchant, and the user may accept the offer. In response to the user’s acceptance, the merchant may provide the request for the redemption transaction to the product awards management system. 
     At block  1806 , the redemption process  1800  includes, based on the request, providing a redemption option. The redemption option may indicate redeemable units from at least one product awards program in the plurality of product awards programs. Redeemable units may be deducted from a product awards program in exchange for an item of value from the merchant. 
     For example, the redemption option may indicate that the user may redeem a value of units from a “Dining Awards” product awards program to purchase the item of value from the merchant. As another example, the redemption option may indicate that the user may redeem a value of units from a “Dining Awards” product awards program in combination with a value of product awards from an “Airline Awards” product awards program to purchase the item of value from the merchant. As still another example, the redemption option may indicate that the user may redeem a value of units from a “Payment Device Awards” product awards program in combination with a value of currency to purchase the item of value from the merchant. In some embodiments, the redemption option may include more than one option. For example, the redemption option may include each of the examples described above. 
     The redemption option may be provided to the user (e.g., through the application on the computing device) and/or may be provided to the merchant. Where the redemption option is provided to the merchant, the merchant may present the redemption option to the user. For example, in a physical retail environment, the merchant may present the redemption option to the user through a point-of-sale terminal. As another example, in an online retail environment, the merchant may present the redemption option the user through a pop-up notification in a web browser application. Other examples are possible as well. 
     The redemption process  1800  includes, at block  1808 , receiving a selection of the redemption option. The selection may be received from, for example, the user (e.g., through the application on the computing device). Alternatively or additionally, the merchant may receive the selection from the user, and the merchant provide the selection to the product awards management system. For example, in a physical retail environment, the merchant may receive the selection through a point-of-sale terminal. As another example, in an online retail environment, the merchant may receive the selection through a pop-up notification in a web browser application. Other examples are possible as well. 
     At block  1810 , the redemption process  1800  includes, in response to receiving the selection, redeeming the redeemable units to conduct the redemption transaction and entering into the blockchain encrypted data associated with the redemption transaction. The encrypted data may be encrypted according to the at least one encryption technique. 
     Redeeming the redeemable units to conduct the redemption transaction may involve, for example, transferring the redeemable units from the at least one product awards program to the merchant and transferring the merchant’s item of value to the user. 
     Entering into the blockchain encrypted data associated with the redemption transaction may involve, for example, entering into the blockchain encrypted data specifying the account, the merchant, the redeemable units, the item of value, and the date and time of the redemption transaction. The transaction may indicate, for example, that the redeemable units were transferred to the merchant and the item of value was transferred to the user. In some embodiments, the redemption transaction may further include, in addition to transferring the redeemable units, the user providing product awards and/or currency in combination with the redeemable units. In these embodiments, the transaction entered into the blockchain may further specify the product awards and/or the currency. An example redemption process is further described in connection with  FIGS.  19  and  20 A- 20 C . 
       FIG.  19    illustrates message flow  1900  in an exemplary redemption process, consistent with disclosed embodiments.  FIGS.  20 A- 20 C  illustrate an application and a blockchain in an exemplary redemption process, consistent with disclosed embodiments. As shown in  FIG.  19   , the message flow  1900  begins with message(s)  1902 , with which a user requests a redemption transaction from product awards management system. In some embodiments, the user may request the redemption transaction through an application  2002  executed on a computing device  2000 , as shown in  FIG.  20 A . For example, the user may select a selection  2004  to “Redeem Your Units!” in the application  2002 . The computing device  2000  may provide the request to the product awards management system. 
     In response to receiving the request, the product awards management system provides a redemption option to the computing device with message(s)  1904 . An example redemption option  2006  is shown in  FIG.  20 B . The redemption option  2006  may specify units from one or more product awards programs associated with the user that may be redeemed to purchase the item of value. In some embodiments, the application  2002  may permit a user to vary units from one or more product awards programs to view various redemption options. For example, a user may increase units from one product awards program while decreasing units from another. As another example, a user may increase units from a product awards program to decrease a payment price. Other examples are possible as well. In some embodiments, the redemption option may include a combination of units with product awards and/or currency. The user may select the redemption option through the application, as shown by message(s)  1906 . 
     In some embodiments, in response to receiving the selection of the redemption option, the product awards management system may provide to the user a redemption certificate with message(s)  1908 . The redemption certificate may take the form of, for example, a bar code, two-dimensional bar code (e.g., QR code), or alphanumeric code for display in the application. Other redemption certificates are possible as well. The user may, with message(s)  1910 , provide the redemption certificate to the merchant to conduct the redemption transaction. 
     With message(s)  1912 , the merchant may conduct the redemption transaction with the product awards management system. In embodiments where the redemption option involved a combination of redeemable product awards and currency, the merchant may additionally conduct a transaction with the financial service provider with message(s)  1914  for the amount of currency indicated in the redemption option. In these embodiments, the currency may be provided using, for example, a payment device and/or cash. 
     The product awards management system may add the redemption transaction to the blockchain at  1916 . The transaction may specify, among other things, the units and the item of value from the merchant. In embodiments where the redemption option involved a combination of redeemable units and product awards and/or currency, the redemption transaction added to the blockchain may specify the product awards and/or currency as well. 
     An example transaction entry into the blockchain is shown in  FIG.  20 C . As shown, a transaction  2010  is entered into blockchain  2008 . The transaction  2010  may specify, for example, the user  2012 , the units  2014 , the merchant  2016 , and the item of value  2018 . The item of value  2018  may be indicated by, for example, a value of the item of value provided in units, currency, or another medium of exchange. In embodiments where the redemption option involved a combination of redeemable units, product awards, and/or currency, the transaction  2010  may further specify the product awards and/or currency. 
       FIG.  21    is a flowchart of an exemplary exchange process  2100 , consistent with disclosed embodiments. In some embodiments, exchange process  2100  may be carried out by a product awards management system, such as product awards management systems  1202  and  1300  described above. 
     As shown, exchange process  2100  includes, at block  2102 , maintaining a plurality of product awards accounts. Each product awards account may include units. In some embodiments, each product awards account may include units for each of a plurality of product awards programs. For example, referring back to  FIG.  12   , product awards management system  1202  may maintain an account for user  1208 . The account may include units for a product awards program associated with, for example, merchant  1210  and units for a product awards program associated with, for example, financial service provider  1212 . For instance, the accounts may include product awards for an “Airline Awards” product awards program and/or product awards for a “Hotel Awards” product awards program. 
     Exchange process  2100  continues at block  2104  with receiving a request for an exchange transaction. The request may indicate offered units from an account. The exchange transaction may be any transaction in which units are exchanged for other units, product awards, and/or currency. For example, an exchange transaction may involve a first user exchanging units for a first product awards program for a second user’s units and/or product awards for a second product awards program. As another example, an exchange transaction may involve a use exchanging units for currency at a financial institution. Other examples are possible as well. The request may be received from the user through, for example, the application executed at the computing device. 
     At block  2106 , the exchange process  2100  may include, based on the request, providing a real-time exchange option. The real-time exchange option may indicate an item of value currently available in exchange for the offered units. The item of value may be, for example, units from another product awards account, product awards from another account, and/or currency. The item of value may be available from another user, a merchant, a financial service provider, and/or another entity. In some embodiments, the exchange option may include more than one option. The exchange option may be provided to the user (e.g., through the computing device) 
     The exchange process  2100  includes, at block  2108 , receiving a selection of the real-time exchange option. The selection may be received from, for example, the user (e.g., through the application on the computing device). 
     At block  2110 , the redemption process  2100  includes, in response to receiving the selection, exchanging in real-time the offered units for the item of value to conduct the exchange transaction and entering into the blockchain encrypted data associated with the exchange transaction. 
     Exchanging the offered units for the item of value may involve, for example, transferring the offered units from the user to an entity offering the item of value and transferring the item of value from the entity offering the item of value to the user. The exchangeable product awards may be exchanged in other manners as well. 
     Entering into the blockchain encrypted data associated with the exchange transaction may involve, for example, entering into the blockchain encrypted data specifying the account, the entity providing the item of value, the offered units, the item of value, and the date and time of the offered transaction. The encrypted data may indicate, for example, that the offered units were transferred to the entity providing the item of value and the item of value was transferred to the user. An example exchange process is further described in connection with  FIGS.  22  and  23 A- 20 C . 
       FIG.  22    illustrates message flow in an exemplary exchange process  2200 , consistent with disclosed embodiments.  FIGS.  23 A- 23 C  illustrate an application and a blockchain  2300  in an exemplary exchange process, consistent with disclosed embodiments. As shown in  FIG.  22   , the message flow  2200  begins with message(s)  2202 A, with which the user requests an exchange transaction from product awards management system. The request for the exchange transaction may indicate, for example, offered units in an account associated with the first computing device. In some embodiments, the user may request the exchange transaction through an application, such as application  2302  executed on computing device  2300  in  FIG.  23 A . The user may indicate the offered units  2306  through the application  2302 , as shown. 
     With message(s)  2202 B, the product awards management system may receive from an entity offering an item of value an offer to exchange the item of value in an exchange transaction. The offer may specify, for example, a value and/or range of values of units for which the entity is willing to transfer the item of value. The item of value may be any of units, product awards, and/or currency. 
     The product awards management system may provide a real-time exchange option to the user with message(s)  2204 A. The real-time exchange option may indicate the item of value available in exchange for the offered units. In some embodiments, the product awards management system may further provide a real-time exchange option to the entity providing the item of value with message(s)  2204 B, which may indicate the units are available in exchange for the item of value The exchange option may be selected by the user with message(s)  2206 A. In some embodiments, the exchange option may also be accepted by the entity providing the item of value with message(s)  2206 B. An example exchange option  2308  is shown in  FIG.  23 B  in an application  2302  executed on a computing device  2300 . In some embodiments, the user may select the exchange option by choosing to “Accept!”. 
     With message(s)  2208 A and  2208 B, the product awards management system may exchange in real-time the offered units for the item of value. At  2210 , the product awards management system may update a blockchain associated with the units to reflect the exchange transaction. The exchange transaction may specify, among other things, the user, the offered units, the item of value, the entity providing the item of value, and a time and/or date for the exchange transaction. 
     An example transaction entry into the blockchain  2310  is shown in  FIG.  23 C . The transaction  2312  may specify, for example, the user  2314 , the units  2316 , the entity providing the item of value  2318 , and the item of value  2320 . The item of value  2320  may be indicated by, for example, a value of the item of value provided in cryptocurrency, another currency, or another medium of exchange. In embodiments where the redemption option involved a combination of redeemable units, product awards, and/or currency, the transaction  2312  may further specify the product awards and/or currency. 
       FIG.  24    illustrates an exemplary architecture for a system  2400  configured to regulate generation of units according to at least one encryption technique associated with a blockchain, consistent with disclosed embodiments. As shown, system  2400  may include an operation platform  2402 . Operation platform  2402  may be configured to maintain a plurality of accounts and/or a blockchain through, for example, product awards management system  2404 . In some embodiments, product awards management system  2404  may include hierarchical data storage that facilitates efficient lookup and aggregation of data, such as data pertaining to accounts and/or a blockchain. In some embodiments, raw data may be sourced, cleansed, and transformed using extract, transform, load (ETL) tools before being stored in the product awards management system  2400 . 
     System  2400  may further include access platforms  2406  and  2408 . Each access platform  2406 ,  2408  may be configured to permit access to operation platform  2402 . For example, access platform  2406  may permit access to operation platform  2402  by one or more product awards issuers  2410 . Product awards issuers  2410  may include entities associated with product awards programs through which product awards  2412  may be earned, such as merchants and/or financial service providers. As another example, access platform  2408  may permit access to operation platform  2402  by one or more merchants  2414 , currency markets  2416 , and/or units markets  2418 . Merchants  2414  may be configured to provide goods, services, and/or information that may be exchanged for product awards at product awards management system  2404  through, for example, goods, services, information – product awards exchanges  2420 . Alternatively or additionally, currency markets  2416  may be configured to provide currency that may be exchanged for product awards at product awards management system  2404  through, for example, currency – product awards exchanges  2422 . Still alternatively or additionally, units markets  2418  may be configured to provide units that may be exchanged for product awards at product awards management system  2404  through, for example, units – product awards exchanges  2424 . 
     Each of access platform  2406  and  2408  may be configured through open application programming interfaces (APIs), such as API plugins. An open API may be, for example, an API that is not specific to the technology of the entity to which access is provided. Typical product awards systems permit access using APIs that require the specific technology of one or more entities. For example, typical product awards systems may permit access to a merchant using an API that requires specific technology of the merchant, while permitting access to a product awards issuer using an API that requires specific technology of the product awards issuer. These specific technology APIs hinder integration of the entities within the product awards system. By contrast, open APIs do not require any specific technology, thereby improving integration of entities within system  2400 . 
     In some embodiments, access platform  2406  may be implemented using one or more open APIs to the product awards issuers  2410 . As another example, access platform  2408  may be implemented using one or more open APIs to the merchants  2414 , currency markets  2416 , and/or units markets  2418 . Through open APIs, system  2400  may improve integration between product awards management system  2404  and product awards issuers  2410 , merchants  2414 , currency markets  2416 , and/or units markets  2418 . This integration may improve the functioning of system  2400  by, for example, minimizing inefficiency and lowering an operation cost of the system  2400 . Moreover, such integration may streamline access by product awards management system  2404  to data collected by one or more of product awards issuers  2410 , merchants  2414 , currency markets  2416 , and/or units markets  2418 , thereby permitting real-time data collection for transactions. Further, such integration may enable system  2400  to support simultaneous transactions. For example, system  2400  may support simultaneous access by, for instance, a merchant  2414  and a product awards issuer  2406 .
