Abstract: Embodiments disclosed provide a virtual currency system within a messaging application by performing operations comprising: launching, within a messaging application, a third-party application; receiving, by the messaging application from the third-party application, a request to perform an ecommerce transaction in relation to an item available for consumption on the third-party application; determining, by the messaging application, an expected attribute for the item based on accessing a database that stores expected attribute information for multiple items; verifying, by the messaging application, that an attribute of the item specified by the request corresponds to the expected attribute for the item; and processing, by the messaging application, the ecommerce transaction in response to successfully verifying that the attribute of the item satisfies a verification criterion based on the expected attribute for the item.

Abstract: Embodiments for communicating and displaying collections of image and video clip content with an opt-out interstitial are described. In one example embodiment, a device receives interface information about a group of content collections from a server computer system. When a user inputs a selection of a first content collection, the device displays images and video clips in a sequence defined by the content collection. Each piece of content is displayed for less than a threshold display time. When the device finishes playing the first content collection, the device presents an opt-out interstitial. Additional content collections generated from content submitted by other client devices can be received from the server computer system, and are presented based on a response input, or a lack of response input, to the opt-out interstitial. Some embodiments include content collections generated by the server computer system, as well as advertising elements presented between content collections.

Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program and a method for presenting a conversation interface in a messaging application to enable a plurality of participants in a conversation to exchange messages with each other. A request from a participant of the plurality of participants to view a list of gaming applications is received. In response to receiving the request, a size of a display region in which to present the list of gaming applications to the participant is determined. Based on the determined size of the display region, a presentation format is selected for displaying the list of gaming applications.

Abstract: The presently-disclosed solution provides cross-ledger transfers between distributed ledgers to achieve highly-scalable transaction throughput. Disclosed are methods and instruction code for writing a cross-ledger transfer in a way that effectively transfers value from a source distributed ledger to a target distributed ledger while preventing double spending of the value. This results in the transformation of the ledgers in that the total value in the source ledger is decreased by the transferred value while the total value in the target ledger is increased by the same amount. Also disclosed are system architectures that utilize cross-ledger transfers between multiple distributed ledgers to achieve highly-scalable transaction throughput. Also disclosed are computer apparatus configured to implement cross-ledger transfers between distributed ledgers. Other embodiments and features are also disclosed.

Abstract: Systems and methods are provided for aggregating media content in an electronic messaging application starts with server system receiving from first client device a first media content item and a selection of client devices including second client device. Server system generates a group including first client device and client devices in the selection. Server system causes a group selectable item including a new item indication to be displayed by client devices included in the group. In response to receiving a first signal that indicates that a first portion of the group selectable item has been selected, server system causes the first media content item to be displayed by second client device. Once the first media content item is displayed for a period of time, server system removes the new item indication from the group selectable item and causes the group selectable item to be displayed by second client device. Other embodiments are disclosed.
