API Description

Topics and Subscriptions

Chasqui can be used to send information from one point to another, this is done through topics. The recepient sets a new topic on chasqui, communicate the topic to the sender and suscribe to the topic. The sender can send data (json objects) to the topic and chasqui will relay the data to the suscribers of that topic.

In uPort this is used to send the uPortId from the mobile app to the dApp (running in a browser). This flow is known as uPort Connect. It is also used for requesting transaction signing when no two-way communication between the dApp and the mobile app is set. This flow is known as uPort Sign
