Back to EpisodesBitcoin's Resilience to Cable Failures
Description
Researchers at Cambridge Centre for Alternative Finance reveal Bitcoins resilience against physical disruptions. After analyzing eleven years of data and sixty-eight real submarine cable failures, they found Bitcoin remains strong unless seventy-two to ninety-two percent of global inter-country cables fail simultaneously. Random cable breaks and price swings have minimal impact. Bitcoins resilience varied from 2014-2017, weakened from 2018-2021 due to mining clustering in East Asia, and improved after Chinas ban in 2021. TOR nodes, used by 64% of Bitcoin nodes for privacy, actually enhance network resilience by clustering in well-connected areas. However, Bitcoin may face risks from deliberate attacks on key cables or top hosts like Hetzner or Amazon.
