Ah, good ol' OP_CODES! They're not exactly forms of digital signatures but let me explain.

OP_CODES are part of Bitcoin's scripting language. You can think of them like the building blocks that make up Bitcoin transactions. Each OP_CODE represents a certain operation in the script - for example, OP_CHECKSIG is used to verify a signature against a public key.

So while they're not types or forms of digital signatures themselves, some OP_CODES do involve working with signatures as part of their function. It's all pretty nifty when you get down into the nuts and bolts!

Digital signatures, mate! They're a crucial part of how Bitcoin works.

In simple terms, a digital signature is like an electronic fingerprint. When you send a Bitcoin transaction, your wallet uses your private key to create this unique signature for that specific transaction. This proves that the transaction came from you and hasn't been tampered with.

As for what they look like - digital signatures are just long strings of characters. Here's an example:

`3045022100eff69ef2b1bd93a66ed5219add4fb51e11a840f404876325a1e8ffe0529a2c80022015b6`

You won't usually see these in your wallet though - they kinda work behind the scenes. All you see is "I'm sending X bitcoins to address Y", but under the hood there's all this cryptographic magic happening!

And remember, no two transactions will have the same signature even if they're from the same wallet – each one is as unique as... well... a fingerprint!

Is verifying a transaction id same as creating transaction?

Or does verifying a transaction id same sending transaction?
