Bitcoin’s decentralized nature makes it resistant to nuclear war, as cryptographer and computer scientist Nick Szabo points out in a Tweet.

Szabo is basing his claims on data from the Bitnodes website that reveals the distribution of Bitcoin full nodes worldwide. A Bitcoin full node maintains a complete record of all of the Bitcoin transactions in history, i.e., the entire blockchain. Technically, only a single Bitcoin full node is enough to keep the network running, or to restart the network if somehow all nodes were turned off.

There are nearly 9,500 Bitcoin full nodes across the globe as of this writing. The greatest concentration of nodes is in the United States, Europe, Indonesia, China, and Japan. However, there are also nodes spread across more remote parts of the globe like Hawaii, various Caribbean islands, Iceland, the Canary Islands off the coast of northwest Africa, Alaska, in the middle of the Indian Ocean, across Siberia, and in Australia and New Zealand.

Considering this, it seems that the chances of all the Bitcoin full nodes being knocked offline are fairly low, even in the event of a really bad nuclear war. Suffice to say, Bitcoin is as close as it gets to being nuclear war proof. is committed to unbiased news and upholding journalistic codes of ethics.
