<p>blockchain.com has a "show scripts" link.</p>

<p>Here's a mainnet LN transaction:

<p>The actual script implemented on Lightning Network is a little bit different from what you quoted. This is the script below and the specification is <a href="https://github.com/lightningnetwork/lightning-rfc/blob/master/03-transactions.md#to_local-output" rel="noreferrer">here</a></p>

<pre><code>OP_IF
    # Penalty transaction

OP_ELSE

    OP_CSV
    OP_DROP

<p>From <a href="https://blog.chainside.net/understanding-payment-channels-4ab018be79d4" rel="nofollow noreferrer">this article</a>, I can understand that a punishment-based bidirectional payment channel (the type used by Lightning) would contain roughly this bitcoin script as one of the outputs:</p>

<pre><code>OP_IF
“+7 days” OP_CHECKSEQUENCEVERIFY OP_DROP
&lt;Bob pubkey&gt; OP_CHECKSIG
OP_ELSE
OP_SHA256 &lt;sha256(Bob secret)&gt; OP_EQUALVERIFY
&lt;Alice pubkey&gt; OP_CHECKSIG
OP_ENDIF
</code></pre>

<p>I guess there are some block explorers that let you visualize the real script being used in a transaction, so can anyone point me to a real LN transaction (in mainnet) that follows the template above?</p>

<p>Thanks</p>

From this article, I can understand that a punishment-based bidirectional payment channel (the type used by Lightning) would contain roughly this bitcoin script as one of the outputs:
OP_IF
“+7 days” OP_CHECKSEQUENCEVERIFY OP_DROP
 OP_CHECKSIG
OP_ELSE
OP_SHA256  OP_EQUALVERIFY
 OP_CHECKSIG
OP_ENDIF

I guess there are some block explorers that let you visualize the real script being used in a transaction, so can anyone point me to a real LN transaction (in mainnet) that follows the template above?
