<h1>Parachains Finality Relay</h1>
|
|
<p>
|
|
Source Relay Chain is running GRANDPA Finality Gadget. Source Parachain is a parachain of the Source
|
|
Relay Chain. Bridge GRANDPA finality pallet is deployed at Target Chain runtime and is "connected"
|
|
to the Source Relay Chain. Bridge Parachains finality pallet is deployed at Target Chain and is
|
|
configured to track the Source Parachain. GRANDPA Relayer is configured to relay Source Relay Chain
|
|
finality to Target Chain. Parachains Relayer is configured to relay Source Parachain headers finality
|
|
to Target Chain.
