Nah, the second line looks like a partial sig but it's cut off. The 'OP_0' and 'OP_PUSHBYTES' bits are script commands.

For a valid digital signature in Bitcoin, you need the full shebang – no shortcuts or missing pieces!

Keep it whole to make it roll! 🔄🔗✅

How about this one?

Is it a valid signature?

The first part looks like a complete signature in DER format. If it matches the transaction and public key, could be valid.

The second string seems like a public key in hex.

But just eyeballing here – real validation happens when the Bitcoin network checks 'em out. Gotta put it through the crypto wringer! 🔄🔒👨‍💻
