Is PoS safer? Developer: The cost to attack Ethereum far exceeds Bitcoin's $10 billion.

Ethereum core developer Justin Drake recently pointed out that the cost of launching a 51% attack on Bitcoin (one of the implementations of a double-spend attack) is about $10 billion, which is much less than the cost of attacking Ethereum.

Ethereum 51% attack costly Drake added that to take full control of the Ethereum blockchain, an attacker would need to hold a 50%+1 stake. Cointelegraph reports that a total of 34,168,987 Ether (ETH) coins are currently staked on Ethereum, with a total value of about $89.6 billion. Thus, the current value of half of Ether is around $44.8 billion. At the same time, the actual cost of the attack may be much higher, as such a large-scale operation may result in a significant increase in the price of Ether (the attacker's demand for ETH) will further drive up the cost of the attack. In addition, Drake emphasized that Ethereum has another unique advantage over Bitcoin. "In the event of a 51% attack, the community level can also identify the attacker and socially punish him," he explains. "This is a unique capability of proof-of-stake (PoS) mechanisms that proof-of-work (PoW) can't," he added. In addition, P2P.org researcher Pavel Yashin also pointed out that "if a centralization problem is detected", the community can also solve the problem through a new fork. Old tokens will be removed and damaged chains will become irrelevant. What is a double-spend attack vs. a 51% attack? Double-Spending Attack refers to an attacker's attempt to spend the same digital currency two or more times. This is exploiting a vulnerability in the blockchain consensus mechanism, where an attacker could trick the network into accepting a spent transaction, compromising the integrity of the transaction. A 51% attack is a form of double-spend attack in which an attacker controls more than 50% of the mining power (PoW system, such as Bitcoin) or staking (PoS system, such as Ethereum) of the blockchain network, thereby manipulating transaction records. This may include reversing a confirmed transaction, preventing new transaction confirmations, or achieving a double spend. 51% attacks are costly and extremely damaging to trust in the network. However, at present, the discussion of 51% attacks is mainly theoretical, and the actual implementation is extremely difficult. Bitcoin requires huge computing power and energy, and Ethereum's PoS mechanism introduces economic and governance deterrence. But all in all, the more resistant the two cryptocurrencies are, the better it is for the stability and trust of the entire cryptocurrency market.
