Study Reveals Bitcoin’s Resilience to Subsea Cable Failures
- 72% to 92% of undersea fiber-optic cables must fail for over a 10% node disconnection in the Bitcoin network.
- Targeted attacks on subsea cable chokepoints could be significantly more damaging, with a critical failure threshold of only 5% to 20%.
- 64% of Bitcoin nodes are hidden from researchers due to Tor routing, enhancing network resilience.
- 87% of historical cable fault events had less than a 5% impact on Bitcoin nodes.
- Cable faults show virtually no correlation with Bitcoin prices, indicating stability in the face of disruptions.
The study highlights that while significant failures in submarine cables could disrupt internet traffic, the Bitcoin network demonstrates strong resilience against such events, particularly through its use of Tor for node obfuscation and geographic diversification.
With a failure threshold requiring up to nearly three-quarters of cables to fail before impacting connectivity, Bitcoin’s infrastructure appears robust against potential disruptions.(Source)
