Bitcoin Network Can Survive 92% of Global Submarine Cable Failures, Study Finds

A new study reveals Bitcoin's network resilience to submarine cable failures, showing it can survive 72-92% of global cable outages during random failures. However, targeted attacks on high-betweenness cables could fragment the network with only 20% damage, and hosting provider failures pose significant risks with just 5% capacity loss.

• →Bitcoin nodes remain connected even if 72-92% of global submarine cables fail simultaneously during random outages.
• →Random infrastructure failures typically disrupt less than 5% of Bitcoin nodes worldwide.
• →Strategic targeting of high-betweenness cables could fragment the Bitcoin network with only 20% of total cable damage.
• →Major hosting providers supporting Bitcoin nodes could cause network disruption with just 5% capacity loss.
• →The study highlights both Bitcoin's infrastructure resilience and potential vulnerabilities to coordinated attacks.
