Load Considerations

Let's take a moment and determine where AWM takes up load:

• Source Avalanche L1: Validators sign the message
• Relayer: Signature aggregation
• Destination Avalanche L1: Validators verify the message using the BLS Public Key registry on the P-Chain

There is no record of the network communication, the signatures, or the message itself on the P-Chain. It solely functions as a registry of the BLS public keys where the destination Avalanche L1 validators read from. Since they each already validate the primary network, they are already tracking the P-Chain.

Thus, sending messages from one Avalanche L1 to another does not put any load on the P-Chain or another part of the Primary Network. This is a crucial feature, as there is no bottleneck or dependencies between Avalanche L1s for cross-chain communication.
