According to a recent study, Bitcoin would have to be affected by the failure of nearly three quarters of undersea fiber optic cables. These cables carry about 99 percent of all international internet traffic.
Research first published In February, and most recently revised in March 2012, researchers Wenbin Wu from Cambridge Centre for Alternative Finance and Alexander Neumueller of the Cambridge Centre for Alternative Finance applied a country cascade models to P2P data between 2014 and 2025. They also verified 68 cable failure events.
It is claimed to be the world’s first study to examine Bitcoin’s resistance to failure of submarine cables. long-standing question What would happen to Bitcoin in the event that internet was disrupted?
Researchers found the critical failure threshold of random cable removal is between 0.72 and 0.92. This means that 72% to 90% of all cables fail to be removed. “inter-country” Before more than 10% network nodes would disconnect, the submarine cable must fail.
The researchers called this an attack on the Bitcoin network. “order of magnitude more effective,” The critical threshold is 0.05 to 0.20.
The Tor Routing provides Greater Resilience
The research also revealed that Tor (the Onion Router), a popular software for encrypting and routing traffic, is a threat. “creates a compound barrier to disruption,” The current concentration of infrastructure for relays in Europe’s well-connected countries is a major concern.
Tor, which is similar to VPNs or virtual private networks (VPNs), bounces web traffic around a network of servers run by volunteers. Each hop of the chain includes a layer for encryption. privacyLike the layers in an onion,.

Tor is used to hide the physical location of nodes in the Bitcoin network. This paper showed that 64% Bitcoin nodes There are two main types of adverbs. “invisible” The researchers.
“Tor adoption increases resilience under current relay geography rather than introducing hidden fragility,” The statement is:
This is because Tor relay infrastructure is concentrated in Germany, France, and the Netherlands — countries with extensive and redundant submarine cable connectivity — so cable failures rarely take down relay capacity.
There is a very low correlation between BTC and cable news.
The researchers found that 87% out of 68 historical verified cable faults caused less than 5 % node impacts, while cable events showed virtually zero correlation to Bitcoin.BTC) prices, or a statistically insignificant correlation coefficient of −0.02.
The geographic diversity of the United States is also noted. BTC mining “has not materially altered infrastructure resilience,” It is more likely to be consistent with physical cable distribution than with hashrate.
