So far, the world's fastest supercomputer is Frontier (OLCF-5) at the US National Laboratory.
The peak performance is 15*10^18 times per second, which means it can run 150 trillion times per second, and the cost is about 600 million US dollars;
Let’s take a look at the total computing power of Bitcoin. Based on the latest statistics, the average computing power in the last day is 445.5EH/s;
That is 4455*10^18 hashes per second, which means 445.5 trillion hash calculations can be performed per second;
Let's make the most extreme assumption that the time consumed by a hash calculation is the same as the time consumed by a Frontier calculation. Then the computing power of the entire Bitcoin network is equivalent to nearly 300 of the world's fastest supercomputers running at the same time.
The real situation is:
Hash calculations are much more time-consuming, which means that the computing power of the entire Bitcoin network is equivalent to the fastest supercomputers powered on at the same time with several orders of magnitude more than 300.
Meanwhile, as of July 2023, there are 728 supercomputers in the world;
This means that, from the perspective of computing power, no sovereign country on this planet can compete with the computing power of the entire Bitcoin network.
