I'm currently exploring Bitcoin community, thus, I created my Bitcoin wallet using Electrum.

How can I know which one is my wallet address?

Was it Lightning Node IDis consider as wallet address?

Lightning Network is different than Bitcoin address. It is off-chain transaction and Bitcoin addresses are for on-chain transactions.

Nodes in the Lightning Network

A Lightning node is software that connects and interacts with the main blockchain network and also within the Lightning Network itself. The main blockchain here refers to any blockchain network, on which LN is applicable, such as Bitcoin and Litecoin.

Nodes in the Lightning Network differ from those in the Bitcoin network, mainly in how they verify transactions. Nodes in the Bitcoin network must verify every transaction on the blockchain, while the Lightning nodes only verify the transaction that is interacting directly with it.

A Lightning node is the gateway into the Lightning Network. You need to have at least one node running to be able to explore the LN technology and enjoy everything it has to offer. Thanks to decentralisation, anyone can run a node, regardless of the network they’re using.
