Ethereum (ETH) rose more than 9% to hit a new high on Friday. This was days after the network underwent the Altair enhance successfully. ETH, the second-largest blockchain native token by market cap, soared to $ 4,415, ergo, crossing its previous ATH. It goes without saying that different analysts have portrayed various bullish sentiments regarding this flagship token.
On your way to transitioning to a proof-of-stake (PoS) network, you saw recent updates such as Sedan, Londonand Altair. However, there are a few things to consider about this update based on a recently submitted report. White paper. He pointed out that there are 3 attack vectors in a “Ethereum proof-of-work” blockchain.
Computer scientists at Stanford University and the Ethereum Foundation believe in the possibility of specific types of attacks on Ethereum. Tuur Demeester, a Bitcoin enthusiast shared the said paper to highlight the same. It shed light on two key issues including, “short-range reorganizations” and a “delay of the adversary network.”

“With a probability of 99.6%, an opponent with a stake of 0.09% can execute a record 1 for any day”

the titled paper “Three Proof-of-Stake Ethereum Attacks” covered the two types of attacks mentioned above, and here comes the third in line. Paper indicated , “By combining techniques from both refined attacks, we obtain a third attack that allows an adversary with a very small participation fraction and without control over the propagation of network messages (assuming instead the probabilistic propagation of messages) to cause even reorganizations of the network. long-range consensus chain ”.
“Honest but rational or ideologically motivated validators could use this attack to increase their profits or cripple the protocol, threatening the PoS Ethereum security and incentive alignment. The attack may also lead to the destabilization of the consensus due to congestion in vote processing. “
The attack could also lead to “destabilization of consensus of congestion in the processing of votes ”, the authors of the article pointed out. In addition to this, Bram Cohen, founder of the Chia project and creator of BitTorrent, also shared a similar vision. He tweeted,
“Some problems with the ETH2 consensus, we get a third attack that allows an adversary with a very small participation fraction to cause even long-term reorganizations of the consensus chain”
Needless to say, it was criticized almost immediately by different pro-ETH headlines. For example, this ETH proponent opined,
Let’s review your tweet in a year and see what Chia has accomplished against ETH. Please note that your attitude is to reject community members like me
