# IBC RELAYER

In the Inter-Blockchain Communication (IBC) protocol, blockchains do not communicate directly with each other. Instead, a relayer is used to facilitate communication between chains.

The relayer monitors for updates on open paths between IBC-enabled chains and submits these updates in the form of specific message types to the counterparty chain. Clients are then used to track and verify the consensus state.&#x20;

Furthermore, the relayer is responsible for opening paths across chains, creating clients, connections and channels.

## Our validation set up consist of:

* Hight grade dedicated servers running multiple chains.
* Most recent version of [Hermes](https://hermes.informal.systems/tutorials/more-chains/concurrent-instances.html) as relayer sofware developed by [Informal Systems](https://informal.systems/).
* PebbleDB backend as prefer choise to reduce disk i/o. Credit to [Notional Labs](https://notional-labs.github.io/cosmosia/#/snapshot_usage).

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://cosmos-spaces.gitbook.io/cosmos-spaces/relaying-service/ibc-relayer.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
