More specifically, the methods and systems discussed herein related to electronic transaction verification techniques that employ distributed computation methods, such as blockchains, to store transactional data for various web-based interactions, and to verify a transaction source and generate customer offers for these transactions. ## Claims ### Claim 1 A blockchain system, comprising: a blockchain node comprising a memory and a miner; and an access node coupled to the blockchain node configured to: receive a verification request indicative of an electronic transaction, wherein the verification request comprises a source of the electronic transaction; and convert a state of the electronic transaction into binary code for storage and execution by the miner; wherein the miner is configured to: register the source of the electronic transaction as a blockchain record of the electronic transaction in the blockchain system in response to verifying the source of the electronic transaction; receive an information request for the blockchain record; and transmit, responsive to the information request, the blockchain record to an application to cause the application to generate an offer to a user associated with the blockchain record based on interaction data associated with the user, wherein the application is configured to display the offer. ### Claim 2 (depends on 1) The blockchain system of claim 1, wherein the miner is configured to: receive a transaction request to change the state of the verification request; and perform one or more operations to change the state of the verification request based in part on the transaction request; and record the changed state of the verification request in the memory. ### Claim 3 (depends on 1) The blockchain system of claim 1, wherein the offer is generated based on a type of the electronic transaction. ### Claim 4 (depends on 1) The blockchain system of claim 1, wherein the miner is configured to: receive one or more parameters associated with the electronic transaction; and generate the offer to the user based on the one or more parameters. ### Claim 5 (depends on 1) The blockchain system of claim 1, wherein the miner is configured to receive the interaction data comprising a user profile of the user, information about one or more click-throughs, and platform specific information. ### Claim 6 (depends on 5) The blockchain system of claim 5, wherein the user profile comprises a demographic of the user and the offer is based on the demographic of the user. ### Claim 7 (depends on 1) The blockchain system of claim 1, wherein the interaction data comprises a percentage of transactions made via a mobile device through a mobile application, a type of mobile device, and/or a location of the mobile device. ### Claim 8 (depends on 7) The blockchain system of claim 7, wherein the offer is generated based on the location of the mobile device. ### Claim 9 (depends on 1) The blockchain system of claim 1, wherein the offer is generated based on the source of the electronic transaction. ### Claim 10 (depends on 1) The blockchain system of claim 1, wherein the miner is configured to register the offer associated with the electronic transaction in the blockchain system. ### Claim 11 (depends on 1) The blockchain system of claim 1, wherein the source of the electronic transaction comprises a referral website configured to link to a third-party website. ### Claim 12 (depends on 11) The blockchain system of claim 11, wherein the source of the electronic transaction comprises a transaction completion tool referring to the referral website. ### Claim 13 (depends on 1) The blockchain system of claim 1, wherein the electronic transaction comprises an online booking for a vehicle rental, a hotel room, event tickets, or any combination thereof. ### Claim 14 A blockchain system, comprising: a blockchain node comprising a memory and a miner, wherein the miner is configured to update the blockchain node based on a verification request; and an access node coupled to the blockchain node and comprising an application program interface (API), wherein the access node is configured to: receive the verification request indicative of an electronic transaction, wherein the verification request comprises a source of the electronic transaction; and convert a state of the electronic transaction into binary code for storage and execution by the miner, wherein the miner is configured to: register the source of the electronic transaction as a blockchain record of the electronic transaction in the blockchain system in response to verifying the source of the electronic transaction; receive an information request for the blockchain record; and transmit, responsive to the information request, the blockchain record to the API to cause the API to generate and display an offer to a user associated with the blockchain record, wherein the offer is generated based on interaction data associated with the user. ### Claim 15 (depends on 14) The blockchain system of claim 14, wherein the API is configured to convert the state of the electronic transaction or a function of the electronic transaction into a binary message for storage and execution by the miner. ### Claim 16 (depends on 14) The blockchain system of claim 14, wherein the electronic transaction comprises an online booking. ### Claim 17 (depends on 16) The blockchain system of claim 16, wherein the verification request comprises a request to track a source of the online booking, a request to monitor a balance of transactions associated with a purchase during the online booking, or both. ### Claim 18 (depends on 14) The blockchain system of claim 14, wherein the miner is configured to receive a transaction request comprising a request to change a state of the verification request based on the transaction request. ### Claim 19 (depends on 14) The blockchain system of claim 14, wherein the offer is generated based on a type of the electronic transaction. ### Claim 20 (depends on 14) The blockchain system of claim 14, wherein the API is configured to convert or compile the electronic transaction and the information request into a binary message for storage and execution by the miner.
