Most of us have heard of photo voltaic storms, however it’s simple to underestimate what a very highly effective one can do. Throughout a significant photo voltaic eruption, the Solar can blast Earth with a surge of charged particles and electromagnetic power sturdy sufficient to bend our magnetic discipline and push undesirable electrical currents via lengthy energy traces. Probably the most dramatic instance we all know of is the Carrington Occasion of 1859: telegraph techniques sparked and failed throughout continents, gear burned, and vivid auroras appeared in locations the place they need to by no means be seen. Trendy analysis suggests {that a} related occasion right this moment can be way more disruptive, damaging components of {the electrical} grid, knocking out communication techniques, and leaving complete areas instantly and silently offline.
Now think about what such a shock would imply for Bitcoin.
If a Carrington-scale storm took down a big portion of the worldwide electrical energy and communication infrastructure, an enormous share of miners may disappear from the community on the identical second. Image a state of affairs the place about 80% of the hashrate vanishes immediately. Blocks wouldn’t cease, however they’d arrive far much less often whereas the community slowly stabilizes and issue adjusts to the brand new actuality.
This raises a number of intriguing questions. What precisely occurs throughout this slow-block interval? How strong is the system if, on prime of a hashrate collapse, components of the world develop into briefly remoted and proceed mining their very own model of the chain? And the deeper query: is Bitcoin designed to outlive an occasion the place the overwhelming majority of its mining energy goes darkish with out warning?
My intention is solely to grasp how the protocol behaves below such an excessive but bodily believable state of affairs, and whether or not clearer explanations or steerage may assist node operators and miners navigate it.
Thanks upfront to your ideas.
