 ### Rationali  
 There are two major purposes for designing a tracker network that seperates the full BTC/OMNI node services from obd:  
 
-One is to lower the barrier of deploying and using use obd, without waiting days to sync full node data. Another purpose is to make the obd node more adaptable to realistic user scenarios. The user's network is usually unstable and cannot be constantly online. Therefore, trackers play an important role in maintaining network topology, path finding, message relay, reconnection, etc.

The user's network is usually unstable and cannot be constantly online. Therefore, trackers play an important role in maintaining network topology, path finding, message relay, reconnection, etc.
 
 For example, for quickly finding a payment path, each tracker greedly seeks the whole obd network, to build the network topology, which avoids slow fully distributed path finding algorithms. When an obd queries a path to any tracker for a payment, the tracker will be able to response in milli-seconds.
