Virtually three-quarters of all undersea fibre optic web cables (which raise about ninety nine% of global web traffic) would favor to fail to like a large influence on Bitcoin, in line with a eye released earlier this 12 months.
In overview first revealed in February and final revised on March 12, researchers Wenbin Wu and Alexander Neumueller from the Cambridge Centre for Replacement Finance acknowledged they veteran P2P network files from 2014 to 2025 and 68 verified cable fault events to apply a nation-stage cascade model to resolve Bitcoin’s physical infrastructure resilience.
They claim it to be the first longitudinal eye of Bitcoin’s resilience to submarine cable failures, and it helps to retort to a long-standing ask about what would occur to Bitcoin if the rep like been to be disrupted.
The researchers chanced on that the serious failure threshold for random cable elimination sits at 0.72 to 0.92, which implies 72% to 92% of all “inter-nation” submarine cables would favor to fail earlier than more than 10% of network nodes disconnect.
On the opposite hand, the Bitcoin network became all over again at probability of centered attacks on obvious subsea cable chokepoints, with researchers calling it an “describe of magnitude more vivid,” with a main failure threshold of 0.05 to 0.20.
Tor routing affords increased resilience
The attention also chanced on that Tor (The Onion Router) “creates a compound barrier to disruption,” given the modern concentration of relay infrastructure in successfully-linked European countries.
Tor is reminiscent of VPNs (virtual private networks), bouncing web traffic thru a chain of volunteer-streak servers around the field, wrapping every hop in a layer of encryption for privacy, cherish the layers of an onion.

The Bitcoin network uses Tor to obfuscate nodes, which implies their physical locations are hidden. The paper revealed that 64% of Bitcoin nodes are surely “invisible” to researchers.
“Tor adoption increases resilience below modern relay geography rather than introducing hidden fragility,” it acknowledged.
Right here is because Tor relay infrastructure is targeted in Germany, France, and the Netherlands — countries with intensive and redundant submarine cable connectivity — so cable failures no longer incessantly rob down relay capacity.
Advance-zero correlation between cable events and $BTC rate
The researchers concluded that 87% of the 68 verified historical cable fault events prompted decrease than a 5% node influence, and cable events confirmed surely zero correlation with Bitcoin ($BTC) costs, or a statistically insignificant correlation coefficient of −0.02.
To boot they level to that the geographic diversification of $BTC mining “has no longer materially altered infrastructure resilience,” which is in line with physical cable topology rather than with hashrate distribution.
