Ask HN: Putting BitCoin Hashrate to other uses

1 点作者 gggggggg将近 8 年前
The Bitcoin Hashrate is over 7,000,000 TH&#x2F;s. I have no concept of how large this is, but in terms of supercomputer, I am assuming its large. How large is it, (assuming all the same and modern) how many GPUs are we talking to get this large? It is a power station all to itself to power it all?<p>Then, imagine a world where this could be harnessed, what could this do?<p>i.e.: * How long will it take to crack a SSL site * Remember SETI from the early 2000&#x27;s. I am sure NASA would love this power. * Are there genome&#x2F;DNA projects that would take moments to finish rather than years

So, I&#x27;d imagine that the bitcoin network is 99.999999% ASICs now.<p>So what that means is that there will be less machines and less electricity used to generate that 7m th&#x2F;s, compared to GPUs only.<p>Still, it is a massive amount of electricity and metal and man-hours being put to use, that could be on something different.<p>If you just take every GPU and CPU that Nvidia, Intel, AMD, Sun (rip), Huawei etc etc all make, and you add those up, you will get a seriously massive amount of computing power.<p>Check out the top500.org website to see all of the supercomputers out there. They are simulating some cool problems.<p>The bottleneck is software, i.e &quot;what do we do with all this hardware we&#x27;ve chained together&quot;
