<h1>Messages Relay</h1>
|
|
<p>
|
|
Both Source Chain and Target Chains have Bridge Messages pallets deployed. They also have required
|
|
finality pallets deployed - we don't care about finality type here - they can be either Bridge GRANDPA,
|
|
or Bridge Parachains finality pallets, or any combination of those.
|
|
</p>
|
|
<p>
|
|
Finality Relayer represents two actual relayers - one relays Source Chain Finality to Target Chain.
|
|
And another one relays Target Chain Finality to Source Chain.
