Empirical analysis showed that 87% of documented cable failures during the study period resulted in less than 5% impact on Bitcoin nodes.
This suggests that even when internet infrastructure experiences outages, the network continues functioning with minimal disruption.
The researchers modeled the system using a cascade framework to evaluate how failures propagate through interconnected networks.
Their results indicate that Bitcoin’s underlying architecture prevents most disruptions from spreading widely enough to fragment the network.
Targeted Attacks More Effective But Still Limited
While random failures were found to have minimal effects, the study noted that targeted disruptions could pose a greater risk to network connectivity.
However, even coordinated attacks would require between 5% and 20% of strategically important cross-border connections to be disrupted before major network fragmentation occurs.
This threshold remains relatively high given the global distribution of internet routing infrastructure supporting Bitcoin’s peer-to-peer system.
The findings suggest that while targeted attacks are more efficient than random failures, the network still retains substantial resilience due to its decentralized node structure and redundant routing paths.
Tor Usage Strengthens Network Stability
The study also examined the role of Tor, the privacy-focused routing network used by many Bitcoin nodes.
Researchers found that Tor usage improves resilience because relay bandwidth tends to be concentrated in well-connected regions with strong internet infrastructure.
According to the study, this concentration creates additional layers of connectivity that help maintain network integrity even when parts of the underlying internet infrastructure are disrupted.
