Systems, methods, and computer media for blockchain-based communication between applications are provided herein. Using a blockchain-based multi-application communication platform, different applications can create and interact with trusted records. A trusted record represents something quantified and/or tracked through an application. Trusted records are stored in a blockchain. Trusted records can be created by one application and accessed by other applications through the platform. Interactions of the different applications with a trusted record are also stored in the blockchain. The immutability of information stored in the blockchain ensures that the trusted records can in fact be trusted, ensures that interactions with trusted records are memorialized, and removes uncertainty as to which application's records are correct.

Blockchain-based multi-application communication platform

Techniques and solutions are described for facilitating collaborations between entities. A hub computing system is provided that is accessible to multiple client systems. The hub computing system can be used to create instances of collaboration entities, which can be of various defined types. Object instances can be created and included in, or referenced by, the collaboration entity instances. Clients may take various actions with respect to a collaboration entity instance using one or more hub services. At least a portion of the actions taken with respect to a collaboration entity instance can be recorded in a blockchain. The blockchain records can be used to verify actions taken with respect to a collaboration entity instance, and to verify the integrity of collaboration entity instances.

Collaboration hub with blockchain verification

This disclosure provides various embodiments of systems, software, and computerized methods for reducing the number of server requests sent to a web server. In one aspect, the software generates a file reference uniquely identifying a version of a file capable of being cached by a requester. The file reference can comprise a network-addressable location of the version of the cacheable file and a parameter uniquely identifying the version of the cacheable file, where the parameter is separated from the network-addressable location of the version of the cacheable file. The software can further embed the file reference into a web page file, and send the web page file in response to a request for the web page. The parameter may include a plurality of data elements, such as a second instance of the file name, a timestamp, or a version number of the cacheable file.

Method and software for reducing server requests by a browser

A system, article and method of indexing web content is presented. An attribute is generated for a rendered web page rendered by a display component. The attribute includes a uniform resource locator to the rendered web page, and the rendered web page is associated with a complex resource structure that defines content of a design time version of the rendered web page. The attribute is added to the complex resource structure, and the uniform resource locator from the attribute is indexed in a search engine index.
