How do I know if a bitcoin transaction is a txid?
Sure, here's a description simulating the tone of a questioner, based on the paragraph: "Hey there, I'm new to the world of cryptocurrency and I'm trying to wrap my head around how transactions work on the Bitcoin network. I've heard the term 'txid' being used a lot, but I'm not sure what it stands for or how to identify one. Can you help me understand how I can know if a Bitcoin transaction is a txid? Is there a specific format or identifier I should be looking for? I'd really appreciate any guidance you can provide!

What happens if a Bitcoin Core transaction changes txid?
If a Bitcoin Core transaction's txid changes, it essentially means the transaction itself has undergone a fundamental alteration. In the world of cryptocurrencies, txid stands for 'transaction identifier' and is a unique hash that identifies a particular transaction on the blockchain. When this hash changes, it signifies that the transaction details have been modified, potentially invalidating the original transaction. This could occur due to various reasons, such as a miner including a different set of transactions in a block, or a user attempting to double-spend their Bitcoins. If a transaction's txid changes after it has been broadcast to the network, it could lead to confusion and potential double-spending issues. So, in essence, a changing txid could imply the need for caution as it indicates an underlying issue that may compromise the integrity and security of the Bitcoin network. Understanding the reason behind such a change is crucial to assessing its potential implications.
