Ethereum’s 51% Attack Costs Exceed Bitcoin’s, Analysis Shows

Justin Drake‘s recent analysis highlights that launching a 51% attack on Ethereum is costlier than on Bitcoin, due to Ethereum’s proof-of-stake model.

The event underscores Ethereum’s more robust security model and its ability to fend off attacks, potentially influencing cryptocurrency market dynamics and perceptions.

Analysis Details

Justin Drake, an Ethereum researcher, estimates attacking Ethereum costs significantly more than Bitcoin. The analysis indicates acquiring 51% control in Ethereum requires staking $44.8 billion. This compares to a $10 billion estimate for a Bitcoin attack.

Drake suggests Ethereum’s proof-of-stake model drastically increases its security compared to Bitcoin’s proof-of-work. Grant Hummer highlights concerns over Bitcoin’s future security budget, suggesting it could fall, lowering attack costs further.

Increased costs for a potential attack reinforce Ethereum’s perceived security effectiveness. This could sway investors and developers towards Ethereum, impacting market trends and influencing blockchain deployment choices.

Justin Drake notes that Ethereum’s social layer offers additional defense against attacks, unlike Bitcoin. He emphasizes that Ethereum’s community engagement lends resilience, deterring potential attackers effectively.
