Abstract—Blockcahin is such a technology that helps us to
use a shared ledger. Although the ledger is in shared manner,
the total system is quiet secure. Bitcoin is a crypto currency
which uses blockchain technology. Value of blockchain is very
high than dollar or some other expensive currency. This is one
of the reasons of encouraging theft attack on the blockchain
technology. In this paper, we want to show the attacks on
blockchain, their targeted area, reason and their possible
proposed solution as review. Besides this, Double spending
attack is a major attack on blockchain which is occurred twice
till now and caused a huge loss of crypto currency. In this
paper, we also want to represent the reasons of these attacks
and propose one solution that can prevent Double Spending
Attack. Our findings will provide some future direction for
new researchers and also help the crypto business analysts to
predict about present security in the aspects of blockchain
network.
Index Terms—Blockchain, bitcoin, attacks, double spending
