Bitcoin's decentralization is often discussed as an impregnable strength. However, its global operation depends on a centralized physical infrastructure: submarine fiber optic cables. A wartime conflict scenario targeting them would reveal a critical vulnerability, fragmenting the network and creating information asymmetries with severe financial consequences for many participants.
Network Fragmentation and Information Asymmetry 🚨
If groups of nodes become isolated due to the failure of trunk cables, the network splits into partitions. Each one continues mining its chain, but without synchronization with the others. When connectivity is restored, only the chain from the partition with the most accumulated hash power survives. Connected nodes could see transactions and blocks that the isolated ones do not, enabling strategies like double-spending or selling assets with privileged information about the real state of the chain.
Fiber Optic Miners vs. Glass Fiber Miners âš¡
In this hypothetical scenario, decentralization turns into a connectivity contest. While one group, luckily located away from the cuts, continues operating normally and accumulating advantages, the other is relegated to a sort of local Bitcoin, as valid as theme park currency. The maxim not your keys, not your bitcoins would update to not your trunk cable, not your valid block. A true exercise in resilience... for those with the right router.
