Hash rate denominations

Mining capability is measured in the number of attempts to find a block a miner can perform.

Each attempt consists of creating a unique block candidate, and creating a digest of the block candidate by means of the SHA-256d, a cryptographic hashing function.

Or, in short, a hash. Since this is a continuous effort, we speak of hashes per second or [H/s].

Hash rate denominations

1 kH/s is 1,000 (one thousand) hashes per second

1 MH/s is 1,000,000 (one million) hashes per second.

1 GH/s is 1,000,000,000 (one billion) hashes per second.

1 TH/s is 1,000,000,000,000 (one trillion) hashes per second.

1 PH/s is 1,000,000,000,000,000 (one quadrillion) hashes per second.

1 EH/s is 1,000,000,000,000,000,000 (one quintillion) hashes per second.

1 ZH/s is 1,000,000,000,000,000,000,000 (one sextillion) hashes per second.

Conversions

1 MH/s = 1,000 kH/s

1 GH/s = 1,000 MH/s = 1,000,000 kH/s

1 TH/s = 1,000 GH/s = 1,000,000 MH/s = 1,000,000,000 kH/s

and so forth

SI unit prefixes

The denomination of hash rates follows the International System of Units (SI).

Hereby, the prefixes kilomegagigaterapetaexa, and zetta each translate to an increase by a factor of one thousand.

Please note, that the symbol for kilo is a lower-case “k”. As “K” is the symbol for kelvin, the unit of thermodynamic temperature.

Inconsistency of kilobyte, megabyte, and gigabyte

The computer industry’s use of kilobyte, megabyte, and gigabyte is inconsistent with the SI.

The Joint Electron Device Engineering Council (JEDEC) has redefined the prefixes kilo, mega and giga in relation with bit and byte as powers of 1024 instead of 1000.

Higher prefixes were not redefined by JEDEC.

In order to avoid this inconsistency, the International Electrotechnical Commission (IEC) has proposed the binary prefix which uses kibi[Ki], mebi [Mi], and gibi [Gi] for 1024¹, 1024², and 1024³ respectively.

The War for a Free Internet

The War for a Free Internet

David Vorick

Feb 14

” I came of age on the Internet. By the age of 13, I had more friends whose faces I would never see than I had peers in the classroom. Most of them won’t realize today who I am even if they are reading this now. Most of them didn’t realize I was decades their junior.

When my father was growing up, his freedom was his bicycle. It gave him access to friends, to a job, freedom from his parents, and ultimately space to carve out a personality that he could call his own. He wanted nothing more than to pass these gifts along to me, and it was often to his dismay and frustration that I never found the same joy in my bike that he had found in his.

I was too young to realize it at the time, but I had received the same gifts as my father.

Where my father’s freedom was his bicycle, my freedom was my keyboard.

A denizen of dozens of forums and hundreds of websites, countless hours each weekend contributed elements to my personality that raised me to be someone beyond anything I could have become in my hometown alone.

As middle school became high school, my online hours began to exceed my offline hours. By my sophomore year of college I was spending more than 80 hours per week on the Internet.

The Internet has become the keystone of modern society, a fact that has not been overlooked by our corporate giants.

As the 2010’s progressed, the Internet became a massive land grab. A hundred thousand independently operated forums became one front page of the Internet.

Personal cards, handwritten letters, and cozy phonecalls turned into a single wall that wished you “Happy Birthday” 1,000 times on what was often not even the right day.

What used to be an endless exploration of hand curated forums and webpages turned into a bottomless pit of AI generated filth carefully crafted by teams of PhDs with the sole intention of getting you to stare at your phone for just a little bit longer.

The modern Internet has been absolutely steamrolled by the likes of Google, Facebook, and Amazon.

As these platforms have festered, they’ve made it clear that we’re here to play by their rules.

They decide which of our friends we get updates from.

They decide how large a nose ring can be before a content creator gets demonetized and loses their livelihood.

An uncomfortable percentage of our time is spent under the tyranny of whatever logic was implemented in the pursuit of higher profits next quarter.

Somewhere underneath it all, real people are living every day, taking what breaths they can between the inescapable deluge of content spawning from a clinical addiction to their devices.

The next wave of teenagers are coming of age in this environment and they are suffocating. Suicide rates are up almost 50% since 2007 for people under the age of 24.

The modern Internet is making us miserable.

Our overlords have captured our souls by bringing us gifts of amazing technology and bundling with those gifts chains and cages that capture our minds and manipulate us to maximize their bottom line.

The time has come to stand up for ourselves, for our health, and for the next generation.

The time has come to start the War for a Free Internet. “

CoinMarketCap.com is LYING to everyone while profiting from it

Intro: How CoinMarketCap (CMC) manipulates the market by showing fraudulent information to the community.

CoinMarketCap.com is LYING to everyone while profiting from it
.

It has come to our attention that CoinMarketCap.com, the Number 1 website in the crypto-currency industry, is showing immensely fraudulent and scam information (on purpose) to its users. As a site that is used frequently for reference points by many news organisations, trading outlets, companies, informational sites and individuals, we thought it would be in the best interest of the community to write about what has been really going on with this “trusted resource”.

Please note, our research indicates that multiple attempts to fix information by many coins on CoinMarketCap.com through contacting them through their support requests or online social media sites such as BitcoinTalk.org, reddit.com and other places has gone unanswered, ignored and/or explicitly overlooked/denied. By explicitly overlooked/denied, we mean that after contacting their support with up-to date and obviously correct information, they refuse to update the data. Many hundreds of coins on CMC are affected very negatively (or positively) by this. A lot of them have given up trying to get CMC to put correct data on their site, and have made sticky posts in their own respective forums as to this issue instead.

We also believe that there is massive insider trading going on with the employees, owners and others involved with CoinMarketCap. Our research, including talking to multiple coin creators, shows anomalous buying of coins between times that the coin creators asked CMC to list their coin (through their google form) and between when it actually gets listed on the site. This could mean that CMC insiders know that certain coins will pump, and go on a buying spree to front-run the listing of the coin and the public market sentiment. This can be seen over and over again when analysing the action on coins when being listed.

Pump and dumps are also being actively allowed and managed by the team at CMC without the knowledge of the coin creators or coin communities themselves. This can be seen by the direct manipulation of the circulating supply of some coins. CMC puts the circulating supply as very high at certain points (increasing the market cap), then drops it down to a much lower number later (lowering the market cap). This moves these coins up or down their numbered list causing massive buys and sell offs at the whim of CMC. Luckily this fraud can only be made to happen once or twice with each coin as the public outcry from the coin communities (sometimes) usually puts an end to it one way or other.

There is also evidence of CoinMarketCap effectively “killing” off coins as it sees fit. How does it “kill” a coin? Well it removes it’s circulating supply to “?” or a very low number arbitrarily, and keeps it there for a prolonged period. As the coin goes lower and lower in the rankings, daily volume on the coin dies off until such a time that it is zero (even though the teams behind the coins are still active and growing their ecosystems). This leads to exchanges delisting the coin, and the ecosystem being entirely dead after a period of time. There is plenty of evidence of coin communities complaining and coin creators “begging” CMC to update their information with no luck. CMC literally decides which coin lives or dies with it’s own agendas. In defence of CMC, some coins do lose their circulating supply due to faults of the coins (the data end-points for circulating supply stop working on the servers provided initially by the coins), but many are brought down even with the objections and outcry of the coin creators and communities behind them.

Also of concern is the possible bribery of CMC officials and other nefarious behaviors that could very obviously be extrapolated from their current actions. What if one coin paid a handsome sum to CMC to make sure a “competitor” would have lower market cap? How do you make them have a lower market cap? Easy, refuse to update the circulating supply to what the real numbers are and instead show an arbitrary number of their choosing. This can also be seen on many of the coins listed on CMC. There is ample evidence of coins complaining publicly on many forums yet CMC taking it’s own numbers without any explanation or acknowledgement.

Another area of concern is the outdated/incorrect information of many of the coins listed on CMC. Official coin links being broken or unresponsive, including the main websites, wrong daily volumes (not updated in days or weeks), and hugely different circulating supplies (from those you can officially see on the respective blockchains of the coins themselves) are just some of the additional problems that ring alarm bells with us.

Because of these issues, (and many others including the pseudonymousnature of the founders and team members) we believe it is in the best interest of the entire community to get behind this initiative and make big noise until such a time that CoinMarketCap updates their site to show correct information, or another resource is created/promoted that shows correct and up-to date data on their website. Number 1 can go down to Number 0 very quickly in the space with the right community backlash.

Some may say that these issues may be due to incompetence of the team at CMC or them having limited resources. One of the parts of our analysis will take a much closer look at what kind of income CoinMarketCap really makes. You would be surprised. CMC is one of the most profitable businesses in the entire industry. The user is the product. The ads are the money maker. There are backroom deals, and much more happening beyond the scenes that the public does not know.

Most people here are concerned about centralised mining cartels, hardware producers, banks, governments, regulators and/or core developers being points of issues in this industry. We strongly believe that none of those come even close to comparing to the obvious fraud that has been going on at CoinMarketCap for many years.

The volume of money that is traded on information taken from CMC alone pales every other issue into oblivion. If traders are making buys and sells according to falsified data on CoinMarketCap.com, then they are being manipulated and lied to in one of the biggest frauds in the entire crypto-currency space.

We’re not just shocked at the level of incompetence, negligence, fraud, and outright lying that CMC perpetuates, but at the lack of information about this so far in this industry. For a community that prides itself on self-regulation through transparency and openness, it should be ashamed at not having blown this massive fraud into the public eye much sooner.

Bitcoin Mining Datacenters by the MegaWatt

” Bitcoin Mining Datacenters by the Megawatt

• Last edit: November 27, 2016,

This is an index of publicly known industrial-scale mining operations across the globe.

• Disclaimers:

Because I want to list as many things as possible, this thread has a low standard of proof. Some of the operators listed below may be unethical, scammy, nonexistent, or have rituals where they sacrifice innocent children–I don’t care about that, I just want to make a list.

• Note that there are likely many (secret) mines that aren’t listed here.

• Operational Mines :

• 60MW | BW/ANTPOOL | Unnamed | Inner Mongolia Autonomous Region, China

Note: Power draw is an estimate based off their claim of 100PH, I assumed 0.6W/GH given that this was Feb 2015. Any of you guys have information about this one?

Here’s an interesting paper that explains perhaps why this large datacenter is in this region.

• 3MW | Spondoolies/BTCS | Unnamed | North Carolina, USA

Note: RIP Spondoolies, this is probably shut down.

• TL;DR : Hashrate is concentrated in China, Georgia, the Western US, and Northeastern Canada.

But awesome list. Crazy to see how many farms there are using that much power.

Yeah, but when you get down to it 128MW are owned by one entity–which also happens to be the entity that claims to have the most efficient chips. That’s kinda scary!

• What percentage of the overall MW do you think is with home/retail miners ?

Very little. Most hobbyist miners colocate now unless they can score power for less than $0.06/USD/kwh, otherwise they save money by letting other people take care of their hardware for them. I’d say (and this is a total guess) at most 3MW are being run in homes/businesses. Everything else is probably in datacenters.

When you get down to it 128MW are owned by one entity–which also happens to be the entity that claims to have the most efficient chips. That’s kinda scary!

I find it very scary aswell they seem to be only one pumping out next gen and if they have specs that were reported they are making a killing.

Also they chances will ROI on a lot of machines before other companies even get next gen chips. So when they have ROI’ed and rest is pure profit… that is really scary as what do they do?

My fear is they sell tons of BTC and drag down price. I hope that does not happen though.

it would be nice to have some info, on the maximum megawatt that their location can handle, so they will be forced in the end to split in two or more location

which means better decentralization

I’m pretty sure that MegaBigPower’s mine has grown quite a bit, or they’ve added additional facilities.

Zoomhash also has a biggish mine in the same area, given they’re shipping the used A2 units they have for sale out of there. No clue on size though.

If it’s still owned by the same group of people it’s not decentralized.

I’m pretty sure that MegaBigPower’s mine has grown quite a bit, or they’ve added additional facilities.

Turns out that MBP and hashplex share space in this datacenter :

Data Centers Join the Bitcoin Train

http://www.serverfarmrealty.com/data-centers/titan/

Assuming 60% is used for hosted mining hardware, and the rest is used for other clients–4MW.

It seems to line up with this next article I found which is the motherlode :

http://www.datacenterknowledge.com/archives/2014/11/05/bitcoin-clusters-emerge-in-cloud-computings-footprints/

It reveals that MBP was building a 23MW center and was eyeing another location with 12MW capacity. Another (unlisted so far) NA based hosting company in that article that has 4.5MW of capacity.

Zoomhash also has a biggish mine in the same area, given they’re shipping the used A2 units they have for sale out of there. No clue on size though.

http://zoomhash.com/pages/hosting

That’s another 3MW accounted for.

KNC are a reasonably open company about their mine rollout plans. Another 20 MW rollout.

http://www.pcworld.com/article/3014471/bitcoin-miner-knc-is-planning-another-four-week-datacenter-build-out.html

Also recent Sam Cole interview talking in detail about mining and KNCs search for cheap mining locations.

https://www.youtube.com/watch?v=RDnA6i6oEvA

Washington State has a stack of miners to the extent it is impacting the cheap electricity.

http://www.govtech.com/dc/articles/High-Capacity-Data-Centers-Blindsided-by-Increase-in-Utilities-Charges.html

And who knows what is in China. Bitfury are likely to be mining on their 16nm chip as fast as they can get them.

Just a comment. A nominal X Megwatt Bitcoin Data Centre is only likely to run at the most 60% of capacity for actual mining. There are overheads (cooling etc) and electrical systems and transformers are normally kept at under 80% of capacity.

There’s also Allinvain with Cryptoboreas in Labrador. Don’t know the size of their datacenter though.
