What is confirmation?

If you make a transaction on an exchange, you will see the term confirmation or confirmation. A confirmation means that approval has been given on the transaction that has been created. This can be your own address or someone else’s. Once the transaction is included in one block, it will remain under each subsequent block. Each of these blocks following the transaction in question is a new confirmation of the transaction.

“A confirmation means that approval has been given on the transaction that has been created.”

How many confirmations are (required)?

This differs greatly per cryptocurrency. For example, if you look at Bitcoin, you will see that receiving a payment notification happens almost immediately. Confirmation can sometimes take a few minutes. A confirmation means that there is consensus on the network that the bitcoins you received were not sent to anyone else and are considered your property. Once your trade is included in a block, it will continue to be buried under every block after it, which will exponentially perpetuate this consensus and reduce the risk of a reverse trade. Each confirmation lasts from a few seconds to 90 minutes, with 10 minutes being the average. For example, 6 confirmations are often considered as safe as waiting 6 months for a credit card transaction.
