Abstract: Various embodiments of a technique to securely process and transfer a token in a distributed chain database are described herein. The technique includes receiving a valid call to a transfer function to execute a transfer, intercepting the transfer function call and routing a check function to an authorization service that is executed on a chain database, and determining in the authorization service whether the transfer is authorized. The authorization service includes a state that is controlled by a process that is executed off the chain database and returns a value that indicates whether the transfer can proceed. The system then determines whether to validate or invalidate the transfer in response to the returned value.

Abstract: Membership in a social network is virally expanded by suggesting to a user to invite contacts from the user's address book and, in addition, eligible contacts from other address books. Eligible contacts from other address books include those contacts that have e-mail addresses with the same e-mail domain as the user's e-mail address.

Abstract: Primary and secondary messages are included in a feed according to a “full thread” mode or a “stream” mode. The “full thread” mode causes a feed, when viewed, to include both primary and secondary messages. In contrast, the “stream” mode causes a feed, when viewed, to include only primary messages. In this way, a feed viewed in “full thread” mode provides to users a comprehensive view of messages included in the feed. Alternatively, a feed viewed in “stream” mode provides to users a concise view messages included in the feed.

Abstract: A web page including one or more web applications is generated using third-party scripts, in a manner that protects private content that may be included in the web page. According to this technique, third-party scripts that are to be executed within a browser environment are instead executed by a web server that is generating the web page, so that the web server can protect against any programmatic attempts to improperly access private content included in the web page.

Abstract: An online community bridges two or more different client social networks and includes users of the client social networks and, optionally, one or more users who are not included in the client social networks. The online community provides an area for micro-blogging to be shared between its users while enforcing a separation between it and the client social networks and maintaining the original separation between the client social networks.
