<p>Absolutely! This is why consensus is so important in Bitcoin. If there is a fork in the chain, a transaction could have 1 confirmation on one fork, and 3 on the other fork. Eventually one of these forks is going to win out and become the defacto blockchain.

<p>Is there a chance, that at some point in time, two blocks will have different number of confirmations, according to different nodes? Like, with difference up to 3-4 confirmations?</p>

<p>The problem I'm having that I have <a href="https://github.com/iquidus/explorer" rel="nofollow noreferrer">Iquidus Explorer</a> set up as my <a href="https://chainz.cryptoid.info/slr/" rel="nofollow noreferrer">SolarCoin</a> blockchain viewer and I have 6 as min. number of confirmations until it gets picked up and written in a database, but sometimes, transactions are written there before they show 6 or more confirms <a href="https://chainz.cryptoid.info/slr/" rel="nofollow noreferrer">here</a>.</p>

<p>Thanks in advance!</p>

The problem I'm having that I have [Iquidus Explorer](https://github.com/iquidus/explorer) set up as my [SolarCoin](https://chainz.cryptoid.info/slr/) blockchain viewer and I have 6 as min. number of confirmations until it gets picked up and written in a database, but sometimes, transactions are written there before they show 6 or more confirms [here](https://chainz.cryptoid.info/slr/).

Thanks in advance!
