 # IBC Specification
 
-IBC(Inter-Blockchain Communication) protocol is used by multiple zones on Cosmos. Using IBC, the zones can send coins or arbitrary data to other zones.
+The IBC (Inter Blockchain Communication) protocol specifies how tokens, 
+non-fungible assets and complex objects can be moved securely between different
+zones (independent blockchains). IBC is conceptually similar to TCP/IP in the 
+sense that anyone can implement it in order to be able to establish IBC
+connections with willing clients.
+
 
 ## Terms
 
-How IBC module treats incoming IBC packets is simillar with how BaseApp treats incoming transactions. Therefore, the components of IBC module have their corresponding pair in BaseApp.

 ## MVP Specifications
 
 ### [MVP1](./mvp1.md)
 
-MVP1 will contain the basic functionalities, including packet generation and packet receivement. There will be no security check for incoming packets.

 ### [MVP2](./mvp2.md)
 
-IBC module will be more modular in MVP2. Indivisual modules can register custom handlers to IBC module.

 ### [MVP3](./mvp3.md)
 
-Light client verification is added to verify the message from the other chain. Registering chains with their ROT(Root Of Trust) is needed.

 ### [MVP4](./mvp4.md)
 
-ACK verification / timeout handler helper functions and messaging queue are implemented to make it failsafe. Callbacks will be registered to the dispatcher to handle failure when they register handlers.
