title: "StakeIBC" excerpt: "" category: 6392913957c533007128548e

The StakeIBC Module

The StakeIBC Module contains Stride's main app logic:

  • it exposes core liquid staking entry points to the user (liquid staking and redeeming)
  • it executes automated beginBlocker and endBlocker logic to stake funds on relevant host zones using Interchain Accounts
  • it handles registering new host zones and adjusting host zone validator sets and weights
  • it defines Stride's core data structures (e.g. hostZone)
  • it defines all the callbacks used when issuing Interchain Account logic

Nearly all of Stride's functionality is built using interchain accounts (ICAs), which are a new functionality in Cosmos, and a critical component of IBC. ICAs allow accounts on Zone A to be controlled by Zone B. ICAs communicate with one another using Interchain Queries (ICQs), which involve Zone A querying Zone B for relevant information.

Two Zones communicate via a connection and channel. All communications between the Controller Zone (the chain that is querying) and the Host Zone (the chain that is being queried) is done through a dedicated IBC channel between the two chains, which is opened the first time the two chains interact.

For context, ICS standards define that each channel is associated with a particular connection, and a connection may have any number of associated channels.
