Deep dive into IBC - relaying, custom application, and middleware
IBC Advanced
It is time to dive deeper into IBC!
As you probably already can imagine, relayers are an important concept when dealing with inter-blockchain communication. Thus, you can have a more detailed look at relaying with IBC in the following sections. Then an introduction into IBC custom applications follows, including hands-on exercises on how to extend your checkers blockchain. At the end of the chapter, you can find some sections on IBC middleware elaborating on how you can create a custom IBC middleware and integrate it into your chains.
# In this chapter
In this chapter, you will:
- Explore relaying with IBC, including how to work with the Go and Hermes relayers.
- Take a closer look at custom IBC apps and how to make a module IBC-enabled.
- Discover how to add packet and acknodledgment data.
- Dive into adding modules to existing chains to make them IBC-enabled.
- Understand how to send information from one IBC-enabled chain to another.
- Learn what an IBC middleware is and how to create a custom middleware to integrate it into your chain.
