Bitcoin’s Shroud of Subtlety and Allure

Attacks on Bitcoin

A successful attack on Bitcoin means attacking Bitcoin’s value.

There might well be a bug that could be exploited to put the network out of commission temporarily, but would soon be fixed and then the network would be up and running shortly thereafter.

To destroy Bitcoin permanently means to end the profit opportunities available with it, and that means either a malicious hashing attack on the network that makes mining impossible or such a malevolent policy against Bitcoin trade that even the black market abandons it.

Both of these require spending resources in proportion to the profits that Bitcoin enables.

In this article, I will discuss three reasons why such an attack is unlikely to succeed: antifragility, subtlety, and attacker defection.

The interplay of these three defenses makes Bitcoin into a kind of wave that rewards those who ride it and drowns those who resist it.

The first of these, antifragility, is exemplified in the fact that malicious hashing is impossible up to a certain fraction of the network.

Below the point that selfish mining becomes possible1 additional hashes per second are almost certainly beneficial because they increase the security of the network.

Any potential attacker, therefore, must weigh in the possibility that he may end up benefiting the network instead of destroying it.

A similar risk accompanies a legal attack on Bitcoin. Bitcoin can adapt to half-hearted attacks. It would move deeper into the black market where it would become permanently strengthened.

Furthermore, a legal attack could be easily corrupted into one that brings as many bitcoins as possible to the government agents instead of one that destroys it (see below).

Bitcoin’s Subtlety

Bitcoin adoption happens one person at a time, and this is true for potential attackers as well as the rest of us.

It takes an entrepreneurial mindset to be able to imagine what Bitcoin could become, given how comparatively small it is now.

It takes time and meditation for people to take Bitcoin seriously because most of its value is in the future.

By the time this happens, Bitcoin has become much more expensive than when they first learned of it.

Thus, Bitcoin is protected from attackers by being initially beyond their understanding.

When Bitcoin was very small, it was very stealthy and was completely unknown to the establishment.

Now they laugh at it, just as it has begun to grow bold.

Of course, we don’t know who really dismisses it and who is deliberately trying to draw attention away from it.

Bitcoin’s Allure

Furthermore, potential attackers are at a disadvantage for another reason.

Bitcoin tends to oppose organizations rather than people.

Even someone who stands to lose from Bitcoin by not reacting to it, such as a banker or government agent, stands to gain a great deal by buying now.

Only the very wealthiest people might reasonably expect to be worse off attempting to buy up as much as possible now than if it were gone. (This could happen if their attempt to buy caused the price to rise too fast relative to their ability to acquire additional bitcoins, to the point that they ultimately had less influence over the future Bitcoin economy than they have over the economy of today.)

Thus, the agency problem with Bitcoin affects bitcoin competitors as well as Bitcoin holders.

Nearly any government agent who begins to see bitcoin as a potential threat must also simultaneously see it as an opportunity.

He, too, can invest in Bitcoin. And why shouldn’t he?

Bitcoin may be a threat to his livelihood, but it may well be making him an offer he can’t refuse.

How can an organization that stands to lose by the adoption of Bitcoin provide its members with a better opportunity for staying loyal than Bitcoin provides for defection?

Even those who might resist the temptation to defect would have to think about the defection of his fellows.

How quickly is adoption happening? Is there time to mount an attack before Bitcoin becomes too powerful? How easily could the resources for such an attack be amassed, given both the ignorance and treachery of the other agents.

If such an attack would be unlikely to succeed, then buying now would be the only intelligent action.

Regardless of whether he liked Bitcoin, it would be futile to continue pursuing a doomed cause.

Potential Bitcoin attackers are in a Prisoner’s Dilemma.

In the same way that the people cannot easily rebel against the king owing to a lack of coordination on their part, governments cannot rebel against Bitcoin for the same reason.

The government puts the people in a Prisoner’s Dilemma against one another, and Bitcoin does the same to government agents.

Bitcoin is like Invasion of the Body Snatchers.

Bitcoin attracts inside men to act as covert saboteurs. There have long been predictions from both bitcoiners and naysayers of impending government attacks, but I think there is a possibility that Bitcoin could win without suffering much resistance.

Moreover, although I said above only that any legal bitcoin attack could be perverted, the considerations discussed in this section tend to make such diffusion very likely.

Bitcoin defends itself by being obscure, but once it has attracted someone’s attention, its best interest is for that person to understand the logic presented here. For then he will also understand that his best course is to deny Bitcoin’s threat to his superiors and quietly to become its willing slave.

  1. Right now Bitcoin Core does not follow the proper strategy to protect against selfish mining even at very low hashing rates, but the fix would be extremely easy to implement and would make selfish mining impossible up to 25% of the hash rate. ↩

What is Hashrate ?

Hashrate

Hashrate Bitcoin network h/s
Bitcoin Hash Rate

Hashrate (Hash per second, h/s) is an SI-derived unit representing the number of double SHA-256 computations performed in one second in the bitcoin network for cryptocurrency mining.

Hashrate is also called as hashing power. It is usually symbolized as h/s (with an appropriate SI prefix).

What is hashing power or hash rate?

The hash rate is the primary measure of a Bitcoin miner‘s performance.

In 2014, a miner’s performance was generally measured in Ghash/s, or billions of hashes per second.

The hash/second unit is also part of a common measure of a Bitcoin miner’s electric efficiency in the term watts /Ghash/s, denoted as W/Ghash/s. As 1 watt is equal to 1 joule/s, this measure can also be expressed as J/Ghash, or joules per 1 billion hashes.

Bitcoin network hash rate

Bitcoin network hashrate chart

The hash/s is also used in calculations of the Bitcoin network’s overall hash rate. Because each miner or mining pool only relays a solved block to the network, the overall hash rate of the network is calculated based on the time between blocks.

While not an accurate measure of network hash rate at any given instance in time, measurements over longer periods can be considered indicative and similar calculations are used in Bitcoin’s difficulty  adjustment.

In January 2015, the network hash rate was around 300 Phash/s, or 300 quadrillion hashes per second.

If you compare a bitcoin mining device to one that is designed to mine, for example, Ethereum, you will notice a very large apparent difference in hash rates.

This is because there are many different algorithms that cryptocurrencies use. They all require different amounts of memory and computing power in order to be mined.

To put it simply, bitcoin and its SHA256 algorithm is considered by today standards to be relatively easy to compute. As a result, a mining device that is still relevant today would need to produce hashes in the terahash range and up.

If we were to compare this to Ethereum, you’ll find that most modern Ethereum mining devices (typically GPU’s) operate in the megahash range.

At first glance, you may think that the bitcoin mining device is significantly more powerful or more productive.

While it’s true that it produces more hashes (of the SHA256 variety), this is because bitcoin hashes are easier to produce computationally.

As a consequence, the network difficulty is significantly higher for bitcoin.

To make things even more confusing, some cryptocurrencies intentionally chose algorithms that can only be mined using a basic CPU.

As a result, mining devices for this network that can produce hundreds of hashes per second are considered to be high and very competitive.

So what does all this mean?

Basically, it means that looking at the hash rate alone doesn’t necessarily tell you the effectiveness of the miner.

You also need to understand the network difficulty, and what the norm is for most mining devices for that particular cryptocurrency.

How can I calculate how many hashes I generate per second?

Your problem breaks down nicely into 3 separate tasks:

  • Sharing a single count variable across threads
  • Benchmarking thread completion time
  • Calculating hashes p/sec
  • Sharing a single count variable across threads

Now that we know that not all hashes are the same we need to know how to calculate the estimated profitability of a miner based on its hash rate.

For this, will need to use a mining profitability calculators, they are available in the Internet.

public static class GlobalCounter

 {
   public static int Value { get; private set; }
   public static void Increment()
   {
       Value = GetNextValue(Value);
   }
   private static int GetNextValue(int curValue)
   {
       return Interlocked.Increment(ref curValue);
   }
   public static void Reset()
   {
       Value = 0;
   }
 }

Before you spin off the threads call GlobalCounter.

Reset and then in each thread (after each successful hash) you would call GlobalCounter.

Increment – using Interlocked.X performs atomic operations of Value in a thread-safe manner, it’s also much faster than lock.

Benchmarking thread completion time

var sw = Stopwatch.StartNew();
Parallel.ForEach(someCollection, someValue =>
 {
   // generate hash
   GlobalCounter.Increment();
 });
 sw.Stop();
Parallel.ForEach will block until all threads have finished

Calculating hashes per second

...
sw.Stop();
var hashesPerSecond = GlobalCounter.Value / sw.Elapsed.Seconds;

How is the hash rate measured?

Hash rate is a unit measured in hashes per second or h/s and here are some usual denominations used to refer it.

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.

Common Hash rate 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.

Hey Ho, Hoist the Waffels…

The TSMC and his men stoled the mighty chip out of it's bed,
And bound it on it's pcb plate.
The hasrate be ours, and by the hashrate powers,
It's where we'll roam!
Yo Ho... All you miners,
Hoist the waffels high!
Heave ho, traders and profets,
Never shall We die !
Some miners have perished and some are alive,
Others hold the hashrate high...
With the keys to their wallets...
And a pool's fee to pay,
We lay to Crypto's Creed !
Yo, ho hash together,
Hoist the waffels high!
Heave, ho, traders and profets,
Never shall We die !
Yo, Ho hash together,
Hoist the Waffels high!
The hashrate be ours,
Never shall we die !

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. “
