As the blockchain messages are sent in a secure tunnel using the IPSec tunnel, they are less prone to routing attacks than the case when they are sent using the IP network.
The primary known attacks on the blockchain transactions that are focussed in this paper are delay and partition attacks.
These attacks result from intercepting the ASes path attribute and then changing or prepending AS number to the AS-Path attribute of the BGP protocol to change the traffic flow path.
As a result, the blockchain network is split into two parts, or the transactions are delayed, leading to double spending and other problems in the blockchain network.
For an attacker to attack the BGP routes, the information of the data part of the Blockchain transaction packet or the information of the source/destination IP addresses is crucial.
The other compromised parameter is the AS information of the nodes participating in the blockchain network,
