Node geographic concentration reduced clearnet resilience by 22% from peak to trough during 2018 to 2021.<\/p>\n<p>The 2022 rebound was sharp. The threshold jumped to 0.88 after China&#8217;s mining ban as infrastructure dispersed. Tor adoption accelerated simultaneously.<\/p>\n<p>While the authors avoid single-cause claims, regulatory pressure forced geographic redistribution and drove the adoption of censorship-resistant infrastructure, both of which increased robustness.<\/p>\n<p>Part of the apparent concentration is an artifact of measurement. As Tor adoption grew, the clearnet sample became concentrated in fewer locations. The Herfindahl-Hirschman Index rose from 166 to 4,163, but Hetzner&#8217;s actual share decreased from 10% to 3.6%.<\/p>\n<p>The consolidation reflects changing sample composition, not genuine centralization.<\/p>\n<h2>Clouds are the real risk<\/h2>\n<p>Submarine cable security concerns will escalate. Baltic investigations, the European Commission&#8217;s security toolbox, and reporting on Russian infrastructure all point toward persistent geopolitical anxiety.<\/p>\n<p>For Bitcoin, historical data suggest most cable events are noise.<\/p>\n<p>The actionable infrastructure question is whether policy coordination, cloud outages, or hosting restrictions can produce connectivity shocks at the autonomous system layer.<\/p>\n<p>The ASN-targeted scenario operates at 5% of routing capacity, the threshold for noticeable disruption to reachable clearnet nodes, not consensus failure.<\/p>\n<p>Tor&#8217;s majority share provides a floor under extreme scenarios. Protocol-level mechanisms the study excludes, such as block relay networks, compact block relay, and Blockstream Satellite, add resilience layers that the model does not capture, making estimates conservative.<\/p>\n<p>Bitcoin is not fragile in the way critics imagine, but it is not detached from infrastructure either.<\/p>\n<p>The network has shown graceful degradation under stress rather than catastrophic collapse. Censorship pressure pushed the adoption of infrastructure that strengthened resilience against coordination risks.<\/p>\n<p>The threat model featuring cable-cutting submarines misses the chokepoint closer to home: a handful of networks where coordinated action could create temporary disruption without dramatic seabed operations or acts of war.<\/p>\n<div class=\"post-bottom\">\n<div class=\"post-mentions-and-posted-in\">\n<div class=\"post-info-block post-mentions\">\n<header><span class=\"post-info__label\">Mentioned in this article<\/span><\/header>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>Censorship,Mining,Research#internet #cables #cut #Bitcoin #barely #noticed #researchers #real #chokepoint1772997403<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When seabed disturbances off C\u00f4te d&#8217;Ivoire severed seven submarine cables in March 2024, the regional internet impact earned an IODA severity score above 11,000.
