# 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. 

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).
