““Using an example of how this would work in a more relatable scenario. If you were to imagine a hacker accessing the computer system of your bank and transferring all your funds from your own account into his and deleting all evidence of the transaction, existing technology would not be able to pick this up and you would likely be out of pocket. In the case of a blockchain currency like Bitcoin, having one server hacked with a false transaction being inserted into the database would not be consistent with the same record across the other copies of the database. The blockchain would identify the transaction as being illegitimate and would ultimately reject it meaning the money in your account would be kept safe.””
