Transaction BEEF proofs cannot be accessed on the Transaction History tab

Transaction BEEF proofs cannot be accessed on the Transaction History tab. I used the appimage.

You wrote here that it should be possible:

It should be working, but keep in mind, for old transaction where the UTXOs are already spent, the BEEF proof will no longer show. If you checked it while it had active UTXOs then it would be saved in cache. This is in line with pruning methods and SPV. We are mostly concerned with the active UTXO set. For new transactions, there is no option to choose the BEEF proof until the transaction is confirmed. You can also check the BEEF proofs on the UTXO tab and they go to the same cache as the Transaction history tab. There were some issue in previous iterations with the proofs not showing in the transaction history tab at times. Let me know if it only affects old transactions or new transactions.

Some of the Transactions doesnt show full beef proof:

And if its unconfirmed it doesnt show BEEF, I confirm that.

btw thanks for your work, that SPV functionalty is exactely whats needed.

There is also an Usecase to have BEEF Proof of a unbroadcasted Transaction. Do you plan to support that in future?

"It allows a transaction recipient to prove that the sender has control of the source funds of the payment they are offering without downloading the full Blockchain, by utilising the properties of Merkle proofs. This does not guarantee that the funds have not been previously spent, this assurance is received by submitting the transaction to the Bitcoin miners. However, in such a case the SPV proof acts as strong evidence of fraud backed by legally recognised digital signature technology." - https://wiki.bitcoinsv.io/index.php/Simplified_Payment_Verification

Thanks for testing. When BEEF proof is checked, the wallet queries servers for the UTXOs. If the UTXOs are spent already then it doesn't request BEEF proof. So if you don't check the proof before the UTXO is spent, it won't be saved to cache. There is not much need to have those proofs as the coins are already spent. Some of them are missing just one proof, this is because you likely spent one of the UTXOs in that transaction, so it only provides the proof for the active UTXO when checked. However if you have the hex and can prove even one of the UTXOs are valid, it means the whole transaction and all UTXOs were included in the block. It is designed to minimize server queries, as this is important for SPV and scale.

There can't be BEEF proof for an unbroadcasted transaction because the only way a proof can exist is if the transaction was included in a block, this is also why unconfirmed transactions can't have a BEEF proof. Users can have a BEEF proof of the prior transaction, prior to sending a new transaction P2P.
