Tracking Messages & Packets

When plugs send a message, a MessageOutbound event is emitted with a msgId, which is a unique identifier for each message. This is generated by performing bitwise operations on the local chain ID and message count

The status of a message can be tracked using an API built by Socket. More on this in Status Tracking API

Socket transmits packets from one chain to another. Messages need to get included into these packets to be delivered to the destination chain. Packets are also assigned a unique identifier packetId, generated from the local chain ID, capacitor address and packet count on given capacitor.

Once a message is sent outbound, it will be included in a packet. Packets are periodically sealed by Transmitters and then proposed on the destination chain. Upon sealing, a PacketVerifiedAndSealed event is emitted. This has the packetId and can be used to track the status of the packet a message is included in.
