2^59.8 hashes per second
10^18 hashes per second
1 exahashes (EH) per second
1 quintillion hashes per second
1 billion billion hashes per second
1,000,000,000,000,000,000 hashes per second
Whatever you call it, the global Bitcoin hash rate has hit this arbitrary yet impressive figure. When making hash rate announcements, I prefer to wait for the 3-day average to reach a certain value before claiming the network has reached it, because of variance. See: http://bitcoin.sipa.be/speed-lin-2k.png
Since Bitcoin's launch in January 2009 it has computed:
1.8 × 10^25 hashes
18 septillion hashes
18 million billion billion hashes
(These figures are ±10% accurate—I calculated them by counting the pixels in the area under the curve at http://bitcoin.sipa.be/speed-lin-ever.png)
What does this computational power mean?
The miners' network is by far the largest and fastest publicly known distributed system working synchronously on the same cryptographic problem, namely finding numerically small SHA256 hashes. For example a hash starting with no less than 87 zero bits was found in August 2015: 00000000000000000000013712632da34788a7b4ae2cd78f7982c7036610126b
A Bitcoin hash consists of two calls to the SHA256 compression function, so the network is actually computing 2^60.8 SHA256 compression function calls per second and has computed 2^84.9 compressions total.
With 2^84.9 "operations", a 1024-bit RSA key could have been factored.
With 2^84.9 "operations", a 160-bit ECC key could have been broken.
With 2^84.9 "operations", a SHA1 collision could have been found by simple brute force.
It is estimated the Bitcoin network's power consumption is approximately 150 megawatts.

I am happily married and am the proud Father of a 2 year old boy. I'm definitely an introvert. I really like people, but I do prefer to be alone. I'm more comfortable behind a keyboard than I am at a bar or a club.
I have 2 chihuahuas that are completely insane, and I love them.
My non-work hobbies consist of:
- wood working
- electronics / PC stuff / Linux / Android
However I am very lucky in the fact that my favorite hobby is also my job: SEO.
My Job / Work
I work really odd hours. Generally I wake up at around 11am and am in the office by noon. I work with my crew in the office till 5pm then go home for family time till around 10pm. From 10pm till 5am is where I get the bulk of my work done.
I love working at night. There are no distractions, phone calls, crying children, appointments or anything like that. I get in more work during the 5-10 hours I work overnight than most people do in a week.
I'm the CEO of our company, but I co-run the company with my wife. We work really well together mainly because we stay out of each others way. I've learned enough about relationships over the years to know that spending too much time together can put a strain on your relationship.
I used to blog because it was "good for SEO" but recently I found out that I really love to write. Actually, I love to research. Writing is normally the end result of a process if that makes sense.
I try to do 2-3 posts per week on our company seo blog but I also try to do outreach and guest posting as well.
White Hat vs Black Hat
I am a scientist at heart, so when I first discovered SEO I tried many different tactics. Over the years through seeing hundreds of penalized sites through my colleagues and my own experimentation I've established myself as strictly white hat.
I am a white hat SEO for several reasons:
- I keep ethics at the forefront of not only my job, but my life. Violating the TOS of Google is not something that makes me feel good as a person.
- 90% of the SEO I do is for my clients. It is not right to gamble with other people's websites.
- It works.
- SEO that goes against Google's guidelines is just not a long-term strategy.
I've also found over the years that SEO's group themselves into different categories amongst ourselves.
