A current research led by Lucas Nuzzi, head of analysis and improvement at CoinMetrics, revealed detailed insights into the monetary feasibility of launching a 51% assault on blockchain giants Bitcoin and Ethereum. The research, revealed underneath the title “Breaking BFT,” delves into the financial and logistical challenges of such assaults, offering a nuanced understanding of blockchain safety.
How dangerous is a Bitcoin 51% assault?
Nuzzi shared the findings on X (previously Twitter), highlighting widespread issues inside the crypto neighborhood about cyber vulnerabilities. He mentioned, “The potential for these kind of assaults has prompted nice anxiousness… These are the demons of blockchain safety, however their prices and anticipated utility stay a thriller.”
How a lot does it value to 51% assault Bitcoin and Ethereum?
To search out out, we simulated assault situations.

The analysis introduces a brand new analytical framework, Complete Value of Assault (TCA), which summarizes the prices an attacker would possibly incur when planning a 51% assault. For Bitcoin, this requires buying most ASIC miners and incurring working prices together with electrical energy. The research, which used knowledge from MINE-MATCH and historic ASIC market traits, discovered that the price of procuring the mandatory ASICs may soar to $20 billion. Nuzzi additional defined, “However these ASICs will not be on the market! … In a single case, the price alone was near $20 billion.”
As well as, the analysis additionally explores hypothetical situations the place nation-states create ASICs to hold out assaults. It concluded that “the one mannequin that may be reverse engineered is the S9, which prices over $20B to fabricate.” This highlights not solely the monetary limitations to launching such an assault, but additionally the technical limitations.
How dangerous is the 51% assault on Ethereum?
The research turned its consideration to Ethereum, estimating the price of the assault at greater than $34 billion.This quantity illustrates the necessity to handle greater than 200 nodes and spend $1 million on Amazon Net Providers [AWS] Individually demonstrates the advanced logistics concerned in an Ethereum assault.
The research states, “Opposite to common perception, attackers can’t leverage LSD to buy entry to dam templates… We estimate that an assault on Ethereum would take 6 months attributable to churn limits stopping all stakes from being deployed without delay. “
Nuzzi’s analysis additionally critically evaluates the potential earnings of attacking Bitcoin or Ethereum, contemplating varied methods resembling double-spends and MEV vulnerabilities. The report concludes, “Most significantly, we discovered that attackers can’t revenue from attacking Bitcoin or Ethereum,” underscoring the financial disincentives for such assaults.
Maybe probably the most placing discovering is the empirical proof supporting the existence of Nash equilibria within the safety dynamics of Bitcoin and Ethereum. Based on Nuzzi, “That is the primary empirical proof of a Nash equilibrium in Bitcoin and Ethereum, the place adversarial habits turns into unattractive in comparison with different methods.”
Primarily, the analysis not solely quantifies the numerous prices related to potential 51% assaults on Bitcoin and Ethereum, but additionally reiterates the power of their safety mechanisms. By offering a complete financial evaluation, it removes lots of the uncertainties surrounding blockchain safety and helps present a deeper understanding of the resilience and robustness of those networks towards potential threats.
At press time, BTC was buying and selling at $52,068.
