Valid signatures are like digital proof you got the keys to authorize a Bitcoin transaction.

They show you're legit without revealing your actual private key. It's all math magic – cryptography in action!

So, valid = the network gives it a thumbs up. 👍✨🔐

What about these?

ScriptSig (ASM) OP_0

Are these considered valid signatures?

Those lines are part of a script from a multi-signature transaction. The "OP" parts are operation codes, telling what to do with the data that follows.

The long strings starting with "3044..." are the actual signatures in hexadecimal format. To be valid, they must match the public keys and transaction details using crypto checks.

If they pass those tests on the Bitcoin network, yep, they're valid! 🧐✅🔒

What is crypto check?
