$ETH News from Udayli Ether researcher Justin Drake mentioned that the cost of executing a 51% attack on Bitcoin is about 10 billion dollars, which is significantly lower than the cost of an attack on Ethereum. He pointed out that the PoS mechanism in Ethereum not only increases the cost of an attack but also provides additional security guarantees through the social coordination mechanism within the community. Justin Drake confirmed that the Ethereum community can identify and punish attackers, a feature that the PoW mechanism lacks. Additionally, Matan Sitbon, the founder of Lightblocks for blockchain interaction development, also mentioned that the final security of Ethereum relies not only on encryption or protocol rules but also on the strong social and economic coordination mechanism within the community$ETH
