How secure is 256 bit security? Cryptocurrency - Part 2 of 2

The video explores the complexity of breaking cryptographic security by guessing a 256-bit string, emphasizing the vastness of 2^256. It illustrates the computational power needed for such tasks, using GPUs and hypothetical scenarios like 'kilogoogle' and 'Giga galactic supercomputers'. The video also discusses Bitcoin mining, highlighting the efficiency of ASICs over GPUs.

What is a kilogoogle in terms of computing power, and how does it relate to the number of people on Earth?
