A latest examine spearheaded by Lucas Nuzzi, Head of R&D at CoinMetrics, has dropped at gentle detailed insights into the monetary viability of launching a 51% assault on the blockchain giants, Bitcoin and Ethereum. Revealed beneath the title “Breaking BFT,” this analysis delves deep into the economics and logistical challenges of such assaults, providing a nuanced understanding of blockchain safety.
How A lot Is A 51% Assault On Bitcoin?
Nuzzi took to X (previously Twitter) to share the examine’s findings, emphasizing the prevalent issues inside the crypto group concerning the networks’ vulnerabilities. He remarked, “The mere chance of some of these assaults has triggered vital anxiousness… These are the boogieman of blockchain safety however their prices and anticipated utility stay a thriller.”
How a lot does it price to 51% assault Bitcoin and Ethereum?

The examine introduces a brand new analytical framework, the Complete Value to Assault (TCA), which sums up the bills an attacker would incur in orchestrating a 51% assault. For Bitcoin, this entails buying a majority of ASIC miners and protecting the operational prices, together with electrical energy. Using information from MINE-MATCH and historic ASIC market tendencies, the analysis unveils that the price of procuring the mandatory ASICs might surge to $20 billion. Nuzzi additional defined, “However these ASICs are usually not on the market!… In a single situation, that price alone is near $20 Billion.”
Furthermore, the examine explored the hypothetical situation of a nation-state manufacturing ASICs for an assault. It concluded that “the one mannequin that may very well be plausibly reverse-engineered is the S9, with a producing price north of $20B.” This highlights not simply the monetary, but in addition the technical hurdles in mounting such an assault.
How A lot Is A 51% Assault On Ethereum?
Turning its consideration to Ethereum, the examine estimates an assault price of over $34 billion. This determine accounts for the necessity to handle over 200 nodes and spend $1 million USD on Amazon Internet Providers [AWS] alone, showcasing the advanced logistics concerned in an Ethereum assault.
The examine states, “Opposite to in style perception, an attacker couldn’t leverage LSDs to purchase entry to dam templates… We estimate an assault on Ethereum would take 6 months as a result of churn restrict stopping stake from being deployed unexpectedly.”
Nuzzi’s analysis additionally critically assesses the potential income from attacking Bitcoin or Ethereum, contemplating varied methods similar to double spends and MEV exploits. It concludes that “Most significantly, we discover no methods the attacker would be capable to revenue from attacking Bitcoin or Ethereum,” underscoring the financial disincentives for such assaults.
Maybe essentially the most hanging discovering is the empirical proof supporting the existence of a Nash Equilibrium within the safety dynamics of Bitcoin and Ethereum. Nuzzi posits, “That is the primary empirical proof of Nash Equilibrium in Bitcoin and Ethereum the place adversarial actions turn into unattractive when in comparison with different methods.”
In essence, the examine not solely quantifies the monumental prices related to potential 51% assaults on Bitcoin and Ethereum but in addition reaffirms the energy of their safety mechanisms. By offering a complete financial evaluation, it dispels many uncertainties surrounding blockchain safety, contributing to a deeper understanding of the resilience and robustness of those networks in opposition to potential threats.
At press time, BTC traded at $52,068.
