Hi Siddharth.
I have one question. How can more than 50% of the nodes on the network have an invalid copy which results to attack because other 50% of the nodes on the network still have a valid copy of the previous block? Also, 50% of the nodes cannot simultaneously change the data because it has to be validated by other nodes.
Thanks in advance!!
