How did the blackout in Europe affect the Bitcoin network?
The blackout in European countries, Spain, Portugal, and France led to Bitcoin miners operating there having to cease their activities due to the lack of connectivity to the power grid and the internet.
According to data from the Czech mining pool Braiins, the computational power (hashrate) of the Bitcoin network recorded a slight decrease compared to April 27, from 822 EH/s (exahashes per second) to 807 EH/s. However, this decline does not seem to be largely linked to the massive blackout in Europe.
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 Bitcoin's hashrate has been experiencing a gradual decline since April 17.
