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!

Or does verifying a transaction id same sending transaction?

Ah, no mate, verifying a transaction ID and sending a transaction are two different things. Here's the difference:

1. Sending Transaction: This is when you actually send bitcoins from your wallet to another address. Your wallet signs this with your private key (as we talked about), and then broadcasts it to the Bitcoin network.

2. Verifying Transaction ID: After you've sent a transaction, it gets a unique identifier called a transaction ID (or txid). Anyone can use this txid to look up the details of that specific transaction on the blockchain—like how many bitcoins were sent and where they went.

So in short: sending is all about creating transactions, while verifying is more like... detective work! It's looking up already-made transactions on the blockchain.

Is this a sample of creating/sending/receiving/moving transactions?https://nostrcheck.me/media/public/nostrcheck.me_6452862519581011291690503451.webp
