The buried lede here is we need to think harder about preparing for another solar event like happened in 993 that left its mark in the tree rings, because such events are not all that rare and the next one will destroy GPS and much of the power grid.https://www.nytimes.com/2021/10/20/science/vikings-newfoundland-age.html …

The good news is these massive solar storms happen all the time, it's just rare to get one that hits Earth square-on. So they're not hard to study. The bad news is these massive solar storms happen all the time.

Naturally the blockchain will survive any solar storm, but only if it's oriented east to west, to avoid the worst of the induced currents.

The other good news is that even an 1859-scale solar storm would bring humanity down to near-zero carbon emissions. That is the real power of clean, renewable solar energy.

Finland has more prep than most countries for solar storm effects (e.g. mentioned in 2015 national risk assessment), but unclear if any amount of preparation helps if/when an event of that magnitude occurs.
