<p>If you look closely on blockexplorer.com, you will notice that the site does mention that the transaction was included in block #1484064. The blockexplorer seems to be confused about the height of the blockchaintip, or has some other general issues regarding the confirmation count. For example, it shows all of the transactions in the latest block to have -3562 confirmations: <a href="https://i.sstatic.net/Y8oF9.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/Y8oF9.png" alt="Blockexplorer.com showing transactions in last block with -3562"></a></p>

<p>The transaction in question has some 1300+ confirmations, so this seems to be squarely on blockexplorer.com.</p>

<p>I am curious about the test transaction f72f59a32c1bac47ec87bc3678ec44e98eece5e235d29d79cd1f5461ccc5bf38. Depending on which site I view this transaction, the number of confirmations is positive or negative:</p>

<p>On <a href="https://testnet.blockexplorer.com/tx/f72f59a32c1bac47ec87bc3678ec44e98eece5e235d29d79cd1f5461ccc5bf38" rel="nofollow noreferrer">https://testnet.blockexplorer.com/tx/f72f59a32c1bac47ec87bc3678ec44e98eece5e235d29d79cd1f5461ccc5bf38</a> there are -1797 confirmations.</p>

<p>However on <a href="https://live.blockcypher.com/btc-testnet/tx/f72f59a32c1bac47ec87bc3678ec44e98eece5e235d29d79cd1f5461ccc5bf38" rel="nofollow noreferrer">https://live.blockcypher.com/btc-testnet/tx/f72f59a32c1bac47ec87bc3678ec44e98eece5e235d29d79cd1f5461ccc5bf38</a> there are +1318 confirmations.</p>

<p>Moreover, one of the outputs appears to be spent on blockcypher but unspent on blockexplorer.</p>

<p>I have two questions:</p>

<ul>
<li>Why is there such a difference in the number of confirmations?</li>
<li>Is there something wrong with this transaction? </li>
</ul>
