The present disclosure provides techniques for efficient blockchain transaction processing. In one embodiment, a computer system broadcasts a first transaction to a blockchain network for addition to a block in a blockchain. The computer system may broadcast a second transaction to the blockchain network for addition to the block in the blockchain, where the second transaction descends from the first transaction and includes a placeholder fee. The computer system monitors and determines that the first transaction has not been confirmed to the block in the blockchain for a duration of time (e.g., stuck in the mempool). In response to determining that the first transaction is stuck, the computer system may transmit a request to replace the placeholder fee with a transaction fee that is sufficiently high to cause the first transaction and the second transaction to be confirmed to a block in the blockchain, thereby unsticking the first transaction.

A system may include a memory and a processor in communication with the memory. The processor may be configured to perform operations. The operations may include engaging a user in a primary activity; the primary activity may include a plurality of stages. The operations may include compiling at least one risk-reward score for an advertisement placement of an advertisement for at least one of the plurality of stages. The operations may include identifying a recommended stage for the advertisement; the recommended stage may be based on the risk-reward score. The operations may include displaying the advertisement to the user at the recommended stage.

Methods and systems are provided for providing an alternative payment platform, including method and systems for providing a platform for presenting an alternate offer to a user who is engaged with a primary offer and receiving an indication of the user's engagement with the alternate offer, wherein the user's engagement with the alternate offer serves as an alternative form of payment for an item associated with the primary offer. Such methods and systems may further include methods and systems for selecting one or more alternate offers engagement with which serves as an alternative form of payment for an item associated with a primary offer, presenting the selected alternate payment offers to a user, receiving an indication of engagement with at least one of the alternate offers, receiving payment in exchange for presenting the accepted offer and providing payment to the offeror of the primary offer.

Methods and systems for matching a consumer to benefits offered by enabling organizations provide flexibility and utility to consumers in the marketplace for various products. Information about benefits and enabling organizations are provided and stored in a memory of a computer system. A search query including consumer interest data of a consumer, or results of such a search query, are received. The enabling organization information, benefit information, and search query or information related to the search query results are analyzed automatically in the computer system to provide analysis results, to determine whether any enabling organization to which the consumer is affiliated is offering a benefit for the consumer that is applicable to the said consumer interest data. A message is sent to the consumer including a list of venues ordered according to a search score.

Embodiments described herein disclose methods and systems for managing a digital reputation of a user. The exemplary method can receive information about an item to be purchased by the user, determine in real-time or near real-time, based on one or more financial factors, a first digital reputation score indicative of an effect of the item on the user's digital reputation, determine an alternative item to be purchased instead of the item to be purchased, and determine a second digital reputation score based on the purchase of the alternative item.

Techniques are described for electronic content delivery. One method includes receiving information associated with the prescription order of a user account. In some cases, the information associated with the prescription order includes a medication identifier. The method may include performing a search using the medication identifier to obtain electronic medication documentation. The method may also include transmitting a sponsored content request that includes the medication identifier and receiving sponsored content information responsive to the sponsored content request. The method may further include determining that the user account has authorized communication via a user device and transmitting the electronic medication documentation and/or sponsored content information to the user device. In some examples, the method may include transmitting an indication that the electronic medication documentation and/or sponsored content information was transmitted to the user device.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). Locations of collection, charging and distribution machines having available charged portable electrical energy storage devices are communicated to or acquired by a mobile device of a user, or displayed on a collection, charging and distribution machine. The locations are indicated on a graphical user interface on a map on a user's mobile device relative to the user's current location. The user may use their mobile device select particular locations on the map to reserve an available portable electrical energy storage device. The system nay also warn the user that the user is near an edge of the pre-determined area having portable electrical energy storage device collection, charging and distribution machines. Reservations may also be made automatically based on information regarding a potential route of a user.

A system and methods for an offer placement system for delivering targeted marketing offers to consumers during a session with an online (web-based) Internet portal, such as an online banking portal of a financial institution. A component receives advertising campaign data from an advertiser including a plurality of targeted marketing offers for delivery to consumers in response to a particular condition (e.g. an offer-triggering event), and stores the campaign data in a database. A component determines the occurrence of an offer-triggering event caused by a consumer during an online session with the online portal, for example, viewing a list of banking transactions. A component identifies a predetermined targeted marketing offer stored in the database that corresponds to the offer-triggering event. A component delivers information corresponding to the targeted marketing offer to the consumer during the online session with the portal.

A computer system communicates with sponsors, mobile wireless devices, and wireless service providers to provide the sponsors with access to wireless device users for accepting offers to interact with sponsor content. The system is configured with programmed instructions that when executed by a processor downloads an application program to the mobile wireless devices, the application program being configured to receive incentive offers identifying conditions for receiving credits from one or more of the sponsors, and receive messages from sponsors that transfer money to an account associated with an operator of the computer system so that the sponsors have access to and contact with the wireless devices. The messages that transfer money to the account associated with the operator of the computer system are generated after the application program has been used to accept and perform the conditions identified by at least one incentive offer received by the application program.

A system can determine a first persona for a user identity. The system can generate a web page based on the first persona, wherein respective reinforcement learning agents determine respective content of respective content modules of the website, wherein the reinforcement agents operate on an environment that comprises a group of states, a group of actions, and a group of rewards that are based on the group of states, and respective actions of the group of actions, and wherein a reward of the respective reinforcement learning agents that is increased via reinforcement learning is based on a sum of respective rewards of the respective reinforcement learning agents in transitioning the user identity to a second persona with respect to the website. The system can, in response to receiving first action data indicative of user identity interaction with the web page, transition the user identity to the second persona.
