<h1>Complex 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.<br/>
|
|
</p>
|
|
<p>
|
|
There are 4-6 relayer subprocesses inside the Complex Relayer. They include two message relayers,
|
|
serving the lane in both directions and 2-4 Complex Relayers (depending on the finality type of Source
|
|
and Target Chains).<br/>
|
|
</p>
|
|
<p>
|
|
The following diagram shows the way the complex relayer serves the lane in single direction. Everything
|
|
below may be applied to the opposite direction if you'll swap the Source and Target Chains.
