How will Bitcoin Work When Mining Rewards Run Out?

Let us frame the question, by reviewing what miners really do…

Miners play a critical role in the Bitcoin network. Their activity (searching for a nonce) results in assembling an immutable string of blocks that corroborate and log the universal transaction record. They are the distributed bookkeepers that replace old-school banks in recording and vouching for everyone’s purchase or savings.

From the perspective of a miner, there is no obvious connection between their activity and the worldwide network of bitcoin transactions and record keeping. They are simply playing an online game and competing against thousands of other miners in an effort to solve a complex and ongoing math problem. As they arrive at answers to small pieces of the problem, they are rewarded with bitcoin, which can be easily translated into any currency.

What is the Problem?

One day, mining for rewards will no longer be possible. The fundamental architecture of Bitcoin guarantees that mining will end. The pool of rewards that were held in abeyance as incentives is small and will run out in 2140—about 120 years from now. So, this raises the question: How will we incentivize miners when there is no more reward? (Actually, they won’t really be miners anymore…They will more accurately be bookkeepers or ‘validators’)

Is there a Solution?

Fortunately, there are many ways to offer incentives to those who validate transactions and maintain the books. Here are just a few:

  1. There is a current mechanism in which transactions bid for priority (speed of validation). Today, this mechanism augments the mining reward—particularly during periods of network performance. For example, the extra payments rose to $30 and more for individual transactions just before lightning network was adopted. In the future, it could replace the reward as the basis of a reward system.
  2. At the 2015 MIT Bitcoin Expo, Andreas Antonopoulos proposed a reputation ranking & reward system based on gaming theory. The ideal is that would result in a sufficient reward to maintain continuous network operation. Reputation points are not just a bragging point, but is likely to translate into real-world gravitas and financial opportunities.
  3. I believe that, one day, every user will be a micro-miner, and this will address the issue of incentives. For example, if users can avoid all mining fees by validating one transaction for every 10 of their own, we might see the widespread adoption of wallets that are full or partial nodes, rather than limited to the function of key storage.In this vision, micro mining will be achieved on a phone, a wristwatch, or a linked device at home. It will not result in an escalating race for increased power consumption…

I believe in this last solution and I have proposed it as the path forward at crypto/blockchain conferences.

Today, this idea seems implausible, because of the memory and computational requirements for running a full node. But, there have been big advancements in the effort to support micro-mining—which does not require such resources. Additionally, it is likely that the current proof-of-work mechanism used to arrive at a distributed consensus will be replaced by another mechanism that does not result in a competition to see who can consume the most electricity.

Is Bitcoin Erasing 300 years of Monetary Evolution?

Today, economist and Nobel laureate, Paul Krugman, wrote in the New York Times, that Bitcoin is taking us back 300 years in monetary evolution. As a result, he predicts all sorts of bad things.

A significant basis for Mr. Krugman’s argument is that the US dollar has value because men with guns say it does.

Is Bitcoin erasing 300 years of monetary evolution?

Running with the metaphor that fundamental change to an economic mechanism represents ‘evolution’, I think a more accurate statement is that Bitcoin is not erasing the lessons of history. Rather, it is the current step in the evolution of money. Of course, with living species, evolution is a gradual process based on natural selection and adaptation. With Bitcoin, change is coming up in the rear view mirror at lightning speed.

The Evolution of Money

When a medium of exchange is portable, fungible, divisible, unforgeable and widely accepted, it becomes money. For at least six millennia, barter was gradually replaced by various mediums of exchange.

  • Obsidian —» Cowry shells —» Gold —» Promissory notes (backed by a Bank, employer or wealthy industry) —» Fiat (national currency)

But what backs these forms of money? What gives them value?

The first 3 currencies above were accepted as money on 5 continents. They were backed by their scarcity and unique characteristic properties (Aristotle called this intrinsic value). But even gold cannot serve as a widely used currency today. Although it is portable and scarce, it is not easily tested or subdivided in the field; it is risky to transport and difficult to track; and it is not suited to instant electronic settlement. But what about Fiat money. What backs it?

What Backs National Currencies?

Fiat has been backed by various different things throughout history. They are all compromised attempts to establish confidence and trust. They are compromised, because the fall short of one or more facets of trust.

In the list below, monetary backings in Red are what Mr. Krugman calls “men with guns”. That is, he claims that government demands give value to the dollar:

  • Value tied to gold —» Promise of redemption —» Legal tender (public must accept it for all debts) —» settlement of taxes —» The “good faith and credit” of workers

Unfortunately, the transition away from a trustworthy basis and the constant temptation of kings, dictators and politicians to print money based on credit (or nothing at all—as in the case of our fractional reserve system), has created a house of cards that few people believe is sustainable.

Bitcoin changes all this.

Finally, a crowd-sourced trust basis was invented (or discovered). It is unhackable, un-inflatable, unforgeable and immutable. Most important, it allows a government to be decoupled from its own monetary policy and supply. This is a remarkably good thing for businesses, consumers, creditors, trading partners—and especially for governments.

And Bitcoin is backed by something better than guns, gold or promises. It is provably scarce, capped in supply, completely fair, and built on a massive, crowd-sourced network of bookkeepers and auditors. It is the first currency—and quite probably the last—built on genius math and indisputable trust.

Despite the gross misunderstandings and misconceptions of early pundits, it does not interfere with a government’s ability to tax, to spend or to enforce tax collection—and it does not facilitate crime.

Bitcoin is new, but the goal of distributing trust is not as radical as you might think. It addresses a problem that economists and mathematicians have pondered since Aristotle and the ancient Greeks…

Background

Ever since the transition from real gold to government notes, bank notes and bank ledgers—economists have wondered if value can arise from a public trust that is durable, distributed and stateless. Until 2009, the answer seemed to be that this was impossible because of the double-spend problem.

But 9 years ago, something changed; and the change is dramatic. It will take an additional decade for most people to understand and appreciate this change…

In the first paragraph, I cited Mr. Krugman’s statement that the US Dollar has value because of “men with guns” (a reference to the fact that its use is legally compelled for payment of any debt and for government taxes). But this is not what gives it value. The dollar, the Euro, a Picasso painting and a fresh serving of hot french fries all derive their value from supply and demand. Bitcoin is no different. The trick is to generate viral demand and a ubiquitous infrastructure needed to achieve a robust two-sided network.

In the white paper that introduced both blockchain and Bitcoin (the first blockchain application), Satoshi taught us that a widespread and easy to access communications network (the internet and universal access to smartphones) can give rise to value that is based on a different type of trust. Instead of trust in a government, a bank, or testing the chemistry of a precious metal, value can arise from trust in a formula that is ubiquitous, redundant and constantly monitored and vetted.

All of these things have a value based on demand and the available supply. But with Bitcoin, the medium of exchange (and additionally the store and transfer of value), can be achieved by math, distributed trust and a pure, two-sided network.

So, is Bitcoin taking us backward in time, utility, safety and governance? I have never been awarded a Nobel Prize—but it seems pretty clear to me that Bitcoin is taking us forward and not backward.

President Donald Trump assigned a task force to investigate cryptocurrency fraud

Cryptocurrency fraud and other kinds of cyber-fraud, too.

President Donald Trump has assigned an official task force to investigate the pervasive fraud within the cryptocurrency industry.

On Thursday, the president signed an executive order for a new task force within the Department of Justice with a mandate “to investigate and prosecute crimes of fraud committed against the U.S. Government or the American people, recover the proceeds of such crimes, and ensure just and effective punishment of those who perpetrate crimes of fraud.”

Among the task force’s members are FBI Director Christopher Wray and Deputy Attorney General Rod Rosenstein. Representatives from the Securities and Exchange Commission, the Federal Trade Commission, and the Consumer Financial Protection Bureau will also be called upon for guidance.

Thailand Leads in Crypto

Securities, or not securities. That is the crypto question.

Except in Thailand.

While regulators around the world have grappled with the issue of what category digital currencies and assets fall into, Thailand has skipped the debate altogether.

Instead, using an emergency decree that came into effect earlier this year, authorities wrote an entirely new law.

Extra PCs laying around? Why not mine Bitcoin?

I get this question a lot. Today, I was asked to write an answer at Quora.com, a Q&A web site at which I am the local cryptocurrency expert. It’s time to address this issue here at Lifeboat.

Question

I have many PCs laying around my home and office.
Some are current models with fast Intel CPUs. Can
I mine Bitcoin to make a little money on the side?

Answer

Other answers focus on the cost of electricity, the number of hashes or teraflops achieved by a computer CPU or the size of the current Bitcoin reward. But, you needn’t dig into any of these details to understand this answer.

You can find the mining software to mine Bitcoin or any other coin on any equipment. Even a phone or wristwatch. But, don’t expect to make money. Mining Bitcoin with an x86 CPU (Core or Pentium equivalent) is never cost effective—not even when Bitcoin was trading at nearly $20,000. A computer with a fast $1500 graphics card will bring you closer to profitability, but not by much.

The problem isn’t that an Intel or AMD processor is too weak to mine for Bitcoin. It’s just as powerful as it was in the early days of Bitcoin. Rather, the problem is that the mining game is a constantly evolving competition. Miners with the fastest hardware and the cheapest power are chasing a shrinking pool of rewards.

The problem arises from a combination of things:

  1. There is a fixed rate of rewards available to all miners—and yet, over the past 2 years, hundreds of thousands of new CPUs have been added to the task. You are competing with all of them.
  2. Despite a large drop in the Bitcoin exchange rate (from $19,783.21 on Dec. 17, 2017), we know that it is generally a rising commodity, because both speculation and gradual grassroots adoption outpaces the very gradual increase in supply. The rising value of Bitcoin attracts even more individuals and organizations into the game of mining. They are all fighting for a pie that is shrinking in overall size. Here’s why…
  3. The math (a built-in mechanism) halves the size of rewards every 4 years. We are currently between two halving events, the next one will occur in May 2020. This halving forces miners to be even more efficient to eke out any reward.
  4. In the past few years, we have seen a race among miners and mining pools to acquire the best hardware for the task. At first, it was any CPU that could crunch away at the math. Then, miners quickly discovered that an nVidia graphics processor was better suited to the task. Then ASICS became popular, and now; specialized, large-scale integrated circuits that were designed specifically for mining.
  5. Advanced mining pools have the capacity to instantly switch between mining for Bitcoin, Ethereum classic, Litecoin, Bitcoin Cash and dozens of other coins depending upon conditions that change minute-by-minute. Although you can find software that does the same thing, it is unlikely that you can outsmart the big boys at this game, because they have super-fast internet connections and constant software maintenance.
  6. Some areas of the world have a surplus of wind, water or solar energy. In fact, there are regions where electricity is free.* Although regional governments would rather that this surplus be used to power homes and businesses (benefiting the local economy), electricity is fungible! And so, local entrepreneurs often “rent” out their cheap electricity by offering shelf space to miners from around the world. Individuals with free or cheap electricity (and some, with a cold climate to keep equipment cool) split this energy savings with the miner. This further stacks the deck against the guy with a fast PC in New York or Houston.

Of course, with Bitcoin generally rising in value (over the long term), this provides continued incentive to mine. It is the only thing that makes this game worthwhile to the individuals who participate.

So, while it is not impossible to profit by mining on a personal computer, if you don’t have very cheap power, the very latest specialized mining rigs, and the skills to constantly tweak your configuration—then your best bet is to join a reputable mining pool. Take your fraction of the mining rewards and let them take a small cut. Cash out frequently, so that you are not locked into their ability to resist hacking or remain solvent.

Related: Largest US operation mines 0.4% of daily Bitcoin rewards. Listen to the owner describe the effiiency of his ASIC processors and the enormous capacity he is adding. This will not produce more Bitcoin. The total reward rate is fixed and falling every 4 years. His build out will consume a massive amount of electricity, but it will only grab share from other miners—and encourage them to increase consuption just to keep up.

* Several readers have pointed out that they have access to “free power” in their office — or more typically, in a college dormitory. While this may be ‘free’ to the student or employee, it is most certainly not free. In the United States, even the most efficient mining, results in a 20 or 30% return on electric cost—and with the added cost of constant equipment updates. This is not the case for personal computers. They are sorely unprofitable…

So, for example, if you have 20 Intel computers cooking for 24 hours each day, you might receive $115 rewards at the end of a year, along with an electric bill for $3500. Long before this happens, you will have tripped the circuit breaker in your dorm room or received an unpleasant memo from your boss’s boss.

  • Amateur mining rigs (bottom row below)

This is what you are up against. Even the amateur mining operations depicted in the bottom row require access to very cheap electricity, the latest processors and the skill to expertly maintain hardware, software and the real-time, mining decision-process.

What will it take for Bitcoin to be widely adopted?

Early adopters, speculators and Geeks are never sufficient to bring a new paradigm to market. Mass appeal and adoption of a mechanism that requires education and a change of behavior is never ‘fait accompli’—until it reaches a tipping point. Once at the tipping point, it can go viral without a structured PR campaign and with risks tied only to technology and scalability.

What about early adopters? Can they drive mass adoption?

Somewhat, but not much beyond market awareness. Generally, early adopters drive mass adoption only for evolutionary inventions. For example:

  • The automobile was an evolutionary change to transportation. Although it changed our behavior (maintenance procedures and frequency / distance of travel), it did not require an educational seminar to ride in a car. You either had access to a horse or a car.
  • Likewise, the audio CD and DVD improved media acquisition and enjoyment. But books and seminars were not needed to understand these inventions. Their purpose and use was very similar to the preceding technology: audio tape, records and video recorders.

But some inventions are different. Their use requires that users become acquainted with a technology or process that they didn’t realize they needed! [continue below image]…

The telephone and the Internet led to radical changes in the way we work and interact. You might think that the benefits of a telephone were obvious, even in 1876—and that adoption was driven only by cost and speed-to-market. But this is not the case. When the phone was demonstrated between two cities in Massachusetts, everyone was already aware of Alexander Graham Bell’s clever new gadget. But few people wanted one. A New York Times reporter scoffed that investors were wasting money, because the invention would be of little use to consumers and businesses. It didn’t occur to him that instant, ubiquitous communication (using a device that requires only a voice) would change the face of emergency services or allow close relatives to live far apart without wondering what happened to each other. He wrote that it was a rich man’s toy, useful only for hearing a voice from down the street.

What is required to shift Bitcoin into the mainstream?

Right now, only a small fraction of individuals believe that cryptocurrency presents an improvement over fiat (money issued by a government or bank). Most people don’t yet understand (or accept) that it is backed by something far more tangible than Dollars or Euros—or that it is more fair, or less susceptible to theft and manipulation. And because of spectacular press coverage, many people believe that it facilitates tax evasion, drug deals or worse. There are more misconceptions. For example, realizing that Bitcoin is open source, some individuals feel that other cryptocurrencies could improve on it, and displace it without recognizing the equity of past stakeholders. And finally, many individuals suspect that governments will ban it or issue their own crypto, making the whole issue moot.

Everything in the above paragraph—except the first sentence—is a false perception. But mass appeal and adoption is greatly retarded by false perception.

The adoption of cryptocurrency by mainstream businesses and consumers (not just as a payment instrument, but as the money itself) requires a series of events that are largely predicated on a recent past event. Think of this process as a row of dominos tumbling down—each one falling into the next domino.

The dominos have already started to fall. The process is slow, and it requires a few technical fixes related to cost, scalability, and ease of use. But they are falling and it is becoming clear that secure, decentralized, transparent cryptocurrency will replace nationally minted currencies all over the world. For some influential individuals, this is frightening, impossible or too radical. But this change is inevitable, because the cat is already out of the box and because the benefits to consumers, business and government are almost overwhelming

What are the ‘falling domino’ events and will they occur?

They are listed in the first article below—and, Yes—they are already occuring.

Will governments ever approve of cryptocurrency?

The question was asked of me as columnist at Quora.com: Will governments eventually ‘approve’ of cryptocurrency? First let’s agree on terminology…

  1. By “approve”, I assume that you are asking if governments will adopt or at least tolerate the use of crypto as legal tender in commerce. That is, not just as a payment instrument, but as the money itself—perhaps even accepting tax payments in cryptocurrency.
  2. The word “cryptocurrency” is sometimes applied to altcoins and even to ICOs. These are not the same. Many altcoins meet the criteria of the next paragraph, but none of the ICOs measure up (ICOs are scams). I assume that your question applies to Bitcoin or to a fair and transparent altcoin forked from the original code, such as Bitcoin Cash or Litecoin.

A blockchain-based cryptocurrency that is open source, permissionless, capped, fast, frictionless, with a transparent history—and without proprietary or licensing restrictions is good for everyone. It is good for consumers; good for business; and it is even good for government.

Of course, politicians around the world are not quick to realize this. It will take years of experience, education, and policy experimentation.

Many pundits and analysts have the impression that shifting to cryptocurrency—not just as a payment instrument, but as the money itself—will never be supported by national governments. A popular misconception suggests that a cryptocurrency based economy has these undesirable traits:

  • it is deflationary (i.e. that inflation is necessary to promote spending or to accommodate a growing economy)
  • it facilitates crime
  • it interferes with tax collection
  • It interferes with national sovereignty, which leads to “world government”
  • It is not backed by anything, or at least not by anything substantial, like the Dollar, Euro, Pound, Yuan or Yen
  • it interferes with a government’s ability to control its own monetary policy

Over time, perceptions will change, because only the last entry is true. Adoption of cryptocurrency puts trust into math rather than the whims of transient politicians. It helps governments avoid the trap of hoisting debt on future generations or making promises to creditors that they cannot keep—Yet, it does not lead to the maladies on this list.

But, what about that last item? Does an open source currency cause a nation to lose control over its own monetary policy? Yes! But it is not bad! Crypto cannot be printed, gamed or manipulated. Despite perception, it is remarkably resistant to loss or theft. Early hacks and fiascos were enabled by a lack of standards, tools and education. As with any new technology—especially one that changes practices or institutions—adoption of radical processes goes hand-in-hand with gradual understanding and acceptance of benefits.

How Does Crypto Help Governments?

Adopting/accepting a national (or international) cryptocurrency is a terrific way for governments to earn the respect and trust of citizens, businesses, consumers and especially creditors. There is no more reason for governments to control their money supply than there is for them to control communication networks, space travel or package delivery services.

You may not agree that cryptocurrency is good for government, and so I expand on the topic here. But your question doesn’t ask if it is good, it asks if governments are likely to approve.

Yes. Eventually…

First, a few forward thinking countries like Iceland, Japan or UAE will spearhead adoption of a true, permissionless cryptocurrency (or at least recognize it as legal tender) . Later, ‘stress-economies’ will join the party: These are countries that need to control either rampant inflation, a reluctance to tax citizens, treasury mismanagement or massive international debt. A solution to these problems requires restoration of public trust. I wouldn’t be surprised to see Greece, Zimbabwe, Venezuela or Argentina in the mix.*

Eventually, G7 countries will tread into a growing ocean. Not now; but in 5 or 8 years. The conditions are not yet right. It requires further vetting by early adopters, continued development, education and then popular consumer adoption. But all of these things are inevitable. Eventually, governments will recognize that a capped, trusted, transparent, math-based money is far better for all stakeholders than money based on intrinsic value, promise-of-redemption or force.

* We are not discussing countries that plan to create their own cryptocurrency. None of these plans involve a coin that is open source, permissionless, decentralized and capped. They are simply replacing paper with a national debit card. But it is not crypto.
