$BTC How did the blackout in Europe affect the Bitcoin network?

While the lack of electricity affected the infrastructures of hospitals, banks, and businesses, Bitcoin continued to process its blocks every 10 minutes.

Nodes and miners distributed around the planet allow the network to keep functioning.

The Bitcoin hashrate recorded a slight decrease compared to April 27, although not due to the blackout.

The massive blackout that affected European countries Spain, France, and Portugal on April 28, 2025, tested the resilience of various infrastructures, including the Bitcoin (BTC) network.

The lack of electricity impacted millions of users and households, causing conflicts in telephone networks, internet access, as well as public transportation, flights, operations in hospitals, banks, and traditional businesses, among many others.

That metric, which measures the total processing power dedicated to mining on the network, did not show a significant reduction after the blackout, despite the fact that the Bitcoin hashrate has been experiencing a gradual decline since April 17.

Thus, this data evidences that miners in the affected countries do not concentrate a relevant portion of global computing power. At the time of this writing, Spain and France contribute 0.05 EH/s to the total computing power (0.006%), while Portugal contributes 0.2 EH/s (0.025%), according to Hashrate Index.

Miners located in countries such as the United States, Russia, and China lead Bitcoin mining with estimated shares of 36%, 15%, and 13%, respectively. If the blackout, on the other hand, had taken place in any of these locations, the consequences might have been different.

For example, not due to an incident of this nature, but due to the governmental decision of China in 2021, which prohibited BTC mining, a redistribution of the global hashrate occurred, as miners moved to other regions.
