Bitcoin Resilience Study Reveals Targeted Attack Risk
A study found 72% of undersea cables must fail randomly to significantly impact Bitcoin, but targeted attacks are far more effective.Summary
Research from the Cambridge Centre for Alternative Finance analyzed Bitcoin's resilience to submarine cable failures, concluding that a random failure of 72% to 92% of inter-country submarine cables would be required before over 10% of network nodes disconnect. However, the study highlighted that targeted attacks on specific subsea cable chokepoints are significantly more effective, with a critical failure threshold between 5% and 20% of cables. The research also noted that the adoption of Tor routing increases Bitcoin network resilience because its relay infrastructure is concentrated in well-connected European countries, making 64% of Bitcoin nodes effectively invisible. Historically, 87% of verified cable fault events caused less than a 5% node impact, and there was essentially zero correlation between cable failures and Bitcoin price movements.
