Bitcoin Can Survive 72% Of The World's Submarine Cables Being Cut, But A Targeted Attack On Five Hosting Providers Could Cripple It

Research presented in this CoinDesk report examines Bitcoin's network resilience against infrastructure attacks. The findings indicate the network could survive the loss of 72% of the world's submarine internet cables, due to the distributed nature of node connectivity and the protocol's tolerance for high-latency communication. However, the study identified a more concentrated vulnerability: a targeted attack on just five major hosting providers could significantly disrupt Bitcoin network operations. This concentration risk exists because a meaningful share of Bitcoin full nodes are hosted on cloud infrastructure from a small number of providers. No fraud indicators present. This is a technical security analysis that contributes to the ongoing discussion about Bitcoin infrastructure resilience and decentralization.
