Hi folks,

sorry for maybe asking stupid questions, but I spent some time looking for an answer to my problem, but really couldn't find any clear answer.

I have made a transaction that has been confirmed to have been successfully carried out. The recipient however claims, he did not receive any funds at the respective address. I have obviously double checked several times whether the address and amount match the details that where provided. They do.

Now he wants me to provide a transaction ID to find out what has happened. From my basic understanding the transaction ID is the "transaction hash" and can be looked up at eg. blockchain.com. From here I can see the funds have been sent to this address and I can see a red ball behind this transaction. From what I further understand, this means effectively the funds have been transferred successfully.

Now my three questions are:
1. Is my assumption right that the transaction ID is the transaction hash? If not, what exactly is the transaction ID?
2. Is there any possibility then that his claim can be true in this case and he did not receive the money after all?
3. Do I reveal any additional (personal) data when providing him with this "transaction ID"? I guess not, but I am afraid this might be a fraud after all...

Sorry, maybe this should be posted in the newbie section, apologies if this is the case.

regards
Ashumway
