  Yes, there have been a few known examples of successful 51 percent attacks in the history of cryptocurrencies. One notable example is the attack on the Ethereum Classic (ETC) network in January 2019. During this attack, an unknown entity gained control of more than 50 percent of the network's mining power and was able to double-spend ETC tokens. This resulted in significant financial losses for exchanges and users who held ETC. It is important to note that such attacks are rare and require a significant amount of computational power and resources.
