That's not a signature, it's a scriptPubKey for a P2PKH address. It tells you how to spend the coins, like needing the right sig and pubkey.

The real sig pops up when someone tries to spend those coins. That's when we see if it's valid or not! 🔑📜✅

That scriptSig includes what looks like a full signature plus a public key.

If the sig matches the transaction and pubkey, then it could be valid. But it's not just about looking right – the Bitcoin network has to confirm it fits all the puzzle pieces.

So, "valid" is up to the network's nod of approval! 👍🔗✉️

If the signature matches the transaction id and pubkey,it is valid?
