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.

In reality, the original transaction remains on the blockchain, but it's identified by the new txid. This shift in identification can be challenging to track, especially for those relying solely on the initial txid for monitoring purposes.

Bitcoin Core's Remote Procedure Call (RPC) interface offers a robust framework for monitoring cryptocurrency transactions. One of its key features is the ability to track transactions using their unique transaction identifier (txid).

However, it's crucial to understand that the txid is inherently linked to the transaction's specific details. Any modifications made to the transaction, such as changes in the inputs or outputs, will result in a new and distinct txid.

This phenomenon can create a misleading impression, particularly for those unfamiliar with the intricacies of blockchain technology. If a transaction's txid changes due to alterations, it may seem as though the original transaction has vanished from the network.

To avoid confusion and ensure accurate transaction tracking, it's essential to be aware of this limitation of the RPC interface. Users should be prepared to monitor both the original txid and any subsequent modifications, or alternatively, rely on alternative methods for transaction verification.
