Study Reveals Bitcoin’s Resilience Against Infrastructure Disruptions
- 72% to 92% of the world’s submarine cables must fail simultaneously for significant Bitcoin node disconnection.
- Over 87% of analyzed cable fault events caused less than a 5% impact on nodes.
- The largest event in March affected only about 0.03% of the global Bitcoin network.
- Targeted attacks on key cables can reduce resilience thresholds to as low as 20%.
- 64% of Bitcoin nodes utilize TOR, enhancing network resilience against disruptions.
The study highlights the robustness of the Bitcoin network, showing it can withstand random infrastructure failures but remains vulnerable to targeted attacks on critical components like hosting providers and submarine cables.
In summary, while random cable failures have minimal impact, targeted actions could compromise up to five major hosting providers with just a small percentage of routing capacity removed. (Source)
