The channel opening and channel closing transactions will be among those involving 2 of 2 multisig.

<p>I want to identify transactions submitted from L2 on the Bitcoin blockchain. How I can find these transactions?</p>
<p>For example, in the Lightening network, do transactions wait in Mempool? If not, how the lightning is connected to the Bitcoin blockchain?</p>
<p>Thank you</p>

# How I can detect transactions submitted on bitcoin from L2 Lightening network?

(Asked by: username_0 on 2024-03-19)

I want to identify transactions submitted from L2 on the Bitcoin blockchain. How I can find these transactions?

For example, in the Lightening network, do transactions wait in Mempool? If not, how the lightning is connected to the Bitcoin blockchain?

Thank you

> **how the lightning is connected to the Bitcoin blockchain?**

When a Lightning channel is opened or closed, there is a corresponding transaction on the Bitcoin Blockchain. From what I've read, the opening transaction involves a 2 of 2 multisig output. It can't be distinguished from similar outputs created for reasons other than opening lightning channels.

In between those events there would typically be a large number of lightning transactions, using Lightning channels, that leave no trace in the Bitcoin Blockchain.
