Amir Taaki Answers Your Questions About Bitcoin 262

Last week, you asked questions (many rather pointed!) of Amir Taaki, co-founder of Bitcoin Consultancy, which develops Bitcoin related services, exchanges and Bitcoin itself. (They also own Says Taaki: "When creating video games I spent much time imagining tools to make artists lives easier, and how we could keep funding developers to write free software. One contribution of mine to the community was a site where developers could get funded for developing features and I'd love nothing more than to pay people to write free software." With regard to Bitcoin, similarly, "We need fulltime developers thinking about the problems and solutions needed to keep this system running. We aim to get all the creative thinkers from the community and provide a mechanism for enabling their work." Below find his answers to the questions readers raised.

Is the gold rush over?
by curunir

With BitCoin limited to a pre-determined amount and the difficulty of mining new BitCoins, it seems that this gives a huge advantage to people who got into BitCoin early and have already amassed a considerable amount of BitCoins. Is this true and, if so, do you think this disincentive will undermine BitCoin's ability to become more popular since the majority of the population will have to work so much harder to obtain the currency?

Amir Taaki: It is certainly true that early adopters have been rewarded. I do not think these inequities will be more shocking than those in the real world. Any guesses as to how this will play out is pontification. However, I don't think anyone has proposed a working model for a decentralized secure digital currency where such a thing would not happen. Overall, I believe the properties of this currency will significantly add to the wealth of all peoples, especially those less well off.

by conner_bw

I argue that bitcoin is interesting because it's a locked currency, with a known maximum, and a timeline for that maximum based on contemporary crypto math and radical ideas. There is clearly well thought out timeline for adoption and disruption. It's not just "Cool, new money!" Are you a crypto anarchist, or similar?

A.T.: Yes, I myself am a crypto anarchist. However, not everyone on my team has the same political ideologies and we do not try to push our ideologies on each other. In fact, we have all seen our ideologies change over time with the awareness of new knowledge and information. Ideologies should not be a point of contention, especially when we all see the immense prolific value of a more efficient means of commerce.

If not, then is this another Tulip craze [] and all these news stories and bitcoin currency exchange services being hyped heavily the last month machinations for profiteering?

A.T.: I do not advocate that people speculate on bitcoins. In fact I actively advocate against that because those who are new to bitcoin might see it as just that, a 'craze.' I do however think that the properties of bitcoin are clearly advantageous over the current means of commerce. Although bitcoin is still underdeveloped, everything visible in the modern world can be adapted using bitcoins as a backbone. This will result in all the services of today's world (clearing houses, security, fraud protection, interest bearing accounts...) continuing to be offered, but with far less overhead.

Austrian Acceptance
by MyFirstNameIsPaul

I have found that the Austrians have a hard time accepting the idea of a digital currency. The core of their argument seems to be that digital currencies are not made up of something that had value before being a medium of exchange, such as gold and silver. When I counter to them that BitCoin is made up of code and people pay money for things like video games, they argue that the video game would have to be the thing valued, not the computer code. How do you deal with these kinds of objections?

A.T.: Gold is not a currency in my mind. It is a store of value. I would not want to go to buy bread from my local store and shave off some gold from a bullion and take out a scale and wait for an acid test to be performed. Gold is backed by real world properties.

Bitcoin is backed by the fact that is has unique properties as well:
  • Decentralized
  • No bank holidays
  • International
  • No concept of borders
  • Divisible
  • True micro-transactions possible (new markets feasible)
  • New privacy model
  • Private identity yet transparent
  • Secure
  • You do not have to trust merchant sites (Sony - Playstation) to protect your data
  • Fast Transactions
  • No Charge backs

Useful Calculations?
by Bodhammer

Is there any way to make the calculations more useful (i.e. Boinc) and still maintain the same level of difficulty in the computations? It just seems so wasteful to run Bitcoin at this time.

A.T.: Our world's current infrastructure depends on paying employees, building large buildings, paying for heat, electricity, transportation, lawyers, courts, judges, policemen, government bureaucracies, armies and much more. Doesn't it seem wasteful to rely on tedious and sometimes ambiguous real world laws with a lot of overhead instead of mathematical laws?

When merchants started accepting bitcoins, verifiers (because miners is a misnomer) started to see that their generated coins were worth something. They became competitive and found ways to do the same calculations cheaper which provided security for the network and verified the transactions. Verifiers found out that running these hashing algorithms on one's GPU was far more energy efficient than running them on one's CPU. Specialized software was later constructed for these purposes. Some keep their machines under dry ice. In the not so distant future, hardware FPGAs will be specially designed for this verification process.

The advantages of bitcoin exist because it is an inherently more efficient and less wasteful system. The reward for minting a block, provides a healthy competition that causes the energy cost to be driven down.

Additional privacy layers and smartphones?
by DriedClexler

Is there any serious development underway to make the privacy more robust? There has been talk of "Bitcoin laundry," where large pools swap their coins around between each other to make it harder to connect a coin/address with an owner. But for this to seriously work, it needs a lot more people to be involved in it, and it has to be integrated in a way that's secure (against someone just keeping coins in the middle of a shuffle) and transparent to the user (so they don't have to think about the new addresses they generate, or which coins are optimal to send where for the maximum shuffle). How soon can we expect something like this? Also, how soon will smartphones be able to handle this with the same ease as desktops and notebooks?

A.T.: A bitcoin laundry already exists. The volume on it is very low, but if demand increases in the future then such a service is trivial to setup. A mixing service (as they're called) requires a large volume and therefore a persistent demand.

Smartphones can already use bitcoin :) An Android version of the command line Bitcoin was compiled. Additionally one can use an online wallet service (or a bitcoin exchange) to store their bitcoins.

Lost/forgotten bitcoins?
by algorimancer

One thing that concerns me is the fixed maximum number of bitcoins. Lets say people acquire bitcoins, but the amount isn't enough to worry about, so they never use them, or perhaps their computer crashes and they don't have a backup. My understanding is that these bitcoins are permanently lost from the economy of bitcoins. Over time, the total supply would begin to dwindle, presumably pushing up the value of those that remain, until people become frustrated at the small supply and are motivated to move to a new system, then bitcoin is abandoned. In the real world this happens with dollar bills, but the government can compensate for this by creating more. Is this issue addressed in some fashion?

A.T.: The supply of bitcoins is 21 million. The supply of money is infinite. A bitcoin can currently be divided to 8 decimal places. The loss of bitcoins in the future may lead to some deflation however I expect it to be insignificant. In the very long term, even if there was only 1 bitcoin theoretically in circulation, running the world economy would not be a problem. There exists only 6 MBTC in circulation at this moment.

Extreme instability of Bitcoin vs. USD
by Limerent Oil

Why would any merchant IN THEIR RIGHT MIND want to deal with Bitcoin? With the insane USD-to-Bitcoin exchange-rate gyrations happening lately, why would any serious retailer even bother, when the value of Bitcoin vs. USD could change by 50% or more in just a few hours?

A.T.: As liquidity increases transaction costs decrease. If there was already an appropriate clearing house in place, a merchant would be able to automatically accept bitcoins and liquidate them to dollars. In the same way that people who use the internet are not all cognizant of the communication protocols they are using, I foresee the possibility of merchants offering their products in USD, EUR, GBP, and customers purchasing those products in their local currency. And the underlying mechanism which facilitates this transfer is the bitcoin. Bitcoin would provide these same services that payment services, credit cards or banks do but with much less cost to the merchant and customer.

What about the lack of inflation?
by Cyberax

It's long known that economic growth is severely stunted without some measure of inflation. Adopting bitcoins for the global economy would mean that policymakers lose control on money supply, and while there are advantages in this, disadvantages far outweigh them. Additionally, adopting a global currency standard will deny governments ability to influence currency rates robbing them of yet another way to control the economy. Is there any plan to solve this? Maybe a system of independent bitcoin 'roots' operated by governments would help?

A.T.: Ben Friedman has released a lot of work on E money and how it will affect the future and how governments will adapt. The truth is that the government will still have monopolies on much of the operations of the economy such as fractional reserve banking and the issuing of licenses which allow banks to lend money.

by slim

What are your aspirations for the currency? Do you hope for it to be near-ubiquitous — used by corner shops and mainstream merchants like Amazon? Or are you happy to see a parallel economy grow, as a niche thing? Or something else?

A.T.: I have lofty dreams of a world where people can send money abroad without having to pay 20+% in many cases to rip offs like western union. Where people can raise funds through services like paypal but not have their accounts arbitrarily frozen. Where citizens in developing nations who already oppose their government do not have to pay for wars of genocide out of their own pockets as was the case in ex-Yugoslavia where authoritarian control over the money supply helped finance a terrible war and bring about the worst hyper-inflation in Europe since WWII.

Bitcoin in some form is going to be adopted whether it is used as a unique currency, a payment system or as a clearing house. Our aspiration for bitcoin is to provide competition to the current system making everything cheaper for all. It's about cutting the middleman, democratising money and handing back power to people.

Will governments let it survive?
by merdaccia

We live in a world where the supply and movement of money are controlled by governments, central banks, money laundering laws, and financial institutions. How can BitCoin survive in this world? Middle men like banks stand to lose a fortune in fees and exchange rates, governments stand to lose a fortune in taxes if they can't track money movement, and the black market stands to gain a silent way to move value. For BitCoin to gain adoption, some major retailers need to start supporting it, but given the above risks, what stops a government from telling companies in its jurisdiction that they can't accept it?

A.T.: The US is not the world. If their government forces everyone to continue to use typewriters in lieu of computers and pay through the nose, they can. New and better technology, especially when it is revolutionary, does threaten archaic models and practices. Hopefully there will not be contention. My team is already in contact with SWIFT which has operated for 30 years and is the backbone of international money transfer for over 9000 banks. Many forward thinkers see the advantages of bitcoins but it is easy to understand how those perhaps well-intentioned but not well-versed in what bitcoin is can promote FUD.

Regulatory compliance?
by molo

For those of us interested in developing financial services using bitcoin, how have you dealt with regulatory issues? It seems like the SEC and FINRA in the US would not be keen on unregistered broker-dealers and agents and owners not having the legally required Series 7 and Series 24 certifications. Have you sought the UK equivalent certifications? The requirements of lawyers, accountants, certifications etc. seem to put a very high capital cost on starting a legitimate business offering services in this space.

A.T.: As well as being a developer, I own and operate (the UK exchange site). My team has been in negotiations for a long time now with lawyers and regulators. There is no regulatory process or restrictions now on the running of such services. Non-regulated sectors rarely seek out regulation. However, when it comes to bitcoins, I believe the sooner they are regulated the better. If their regulation is pushed by those who understand what bitcoins are then we may be able to regulate them in the best way possible and show the world they were not created for illegal practices. The sooner they are regulated, the sooner users can have legal assurances that merchants are liable for their operations. The negligence seen at MTGox would never have happened in a regulated market.

Although the FSA have not made any official statement about bitcoins. We at are hoping that we can show to the proper authorities that indeed we have recorded our history of transactions. That all the money in our users accounts is accounted for. This process would dispel the FUD surrounding bitcoins and allow the people of the world to enjoy the freedoms and wealth of bitcoins that much sooner.

Tax avoidance and illicit trading
by slim

Some "benefits" of Bitcoin, from one perspective, appear to be that its cash-like properties lend themselves to tax avoidance (making transactions without declaring them), illicit trading (e.g. drugs or prostitution) and money laundering. Do you view this as a positive, a negative, or neutral? If you view it as a problem, how can the problem be mitigated?

A.T.: Most new technologies can be used for good and bad. Of course I do not condone or agree with the use of Bitcoins for illegal purposes.

However, I really want people to understand one thing. The criminalization of Bitcoin would not stop the illegal activity that surrounds it. In fact, it would help those who use it as a means of engaging in illegal activity by not regulating the purchasing and selling of bitcoins. Criminalization would only stop people from enjoying the tremendous and fruitful benefits of such a system, it would hinder the social good. Regulation would allow the proper authorities to find and charge those who use bitcoins for illegal activities. has kept a clear record of the exchanges which have gone on. Every single transaction is recorded and we are happy to open our books to the proper authorities. We are aggressively advocating and promoting the legalization and regulation of the exchanges.

Bitcoins offer massive potential for positive social change. It would be a sad thing to see Bitcoins outlawed due to ignorance or reactionary feelings. If you outlaw Bitcoin then the illicit trades will still continue, perhaps even proliferate, but the good would disappear.

Kings used to raise capital in order to wage wars. They required popular support before they were able to fund their wars. A common tool in modern day authoritarian regimes is currency manipulation in order to fund their wars of genocide (e.g Milosevic in the 90s). Bitcoin democratises governments.

Quantum Computing?
by SanityInAnarchy

Are there plans to deal with quantum computing, or with any of the algorithms used being compromised?

A.T.: If SHA256 or ECDSA was ever cracked, we'd have far bigger problems to worry about than bitcoin being destroyed. I suspect that there won't be any overnight switch, giving everybody enough time in order to adjust the current system to any changes.

The internet wasn't built perfect. But years of reshaping/patching/incremental design have shaped it into a workable network. Bitcoin will too undergo this transformation with time as it ages.

(More from the call for questions:)

is there ever going to be a bitcoin bank? ... The idea that if you lose or destroy or whatever your computer and lose all your money isn't going to make the general public accept this.

A.T.: Bitcoin now stands at its early stages. It's the kernel of the software stack that will eventually exist for this financial system. Other services and software utilising Bitcoin will exist. A common view is where Bitcoin acts as an automated clearing house between all these user facing services in the future.

Bitcoin's protocol itself will need to be extended in order for it to grow. As the network expands, block sizes could become impossible large once it rivals the transaction volume of a comparable service like VISA or Paypal. To have lightweight clients that don't need to process these large GB sized blocks new protocol commands like a txmatch regex would need to be introduced in order that clients don't need to process the entire block data.

The point to Bitcoin is that you can choose your own level of trust in an external service. One of our group's members, Patrick Strateman, came up with a scheme whereby a wallet could be recovered algorithmically using an email and a password. In the future I expect savings accounts where retrieving the money is an arduous proccess. Then we can go further to where a person has all their funds in a trusted service like with email today- how many people run their own mail servers?

What markets do you think will be the first to most aggressively adopt bitcoins as their currency?

What insights can you offer as to why the US government is having a hostile reaction to bitcoins?"

What kinds of competing P2P currencies are in development, and how will their deployment affect the valuation of bitcoins?

A.T.: Immediately as liquidity improves in exchanges, the best use for Bitcoins will be individuals transferring funds between countries without fees. Our group has a lot of interest from mobile sectors because of the potential as a micropayment system. Currently now in Africa, people use mobile credit as a form of currency to transfer funds across borders, but that's usually less than ideal.

The US government isn't a homogenous entity, and one senator (possibly funded by bankers) made a false claim on Bitcoin- calling it a scheme for drug trafficking networks. It may simply be due to reactionary misunderstanding like the people in Yahoo Finance calling Bitcoin a Ponzi scheme invented by bankers. That's why our group is aggressively pursuing press in order to dispel these myths.


If we eventually use Bitcoin in everyday life, say, in the supermarket, how will we deal with prices in fractions of a Bitcoin? What terminology might we use for something priced at 0.00000005 Bitcoins?

A.T.: The accepted 'standard' is to use SI prefixes. 0.005 BC would be 5 mBC.

Here come the regulators ...

How will your business change when countries regulate exchanges? How do you ensure your exchange isn't being used for illicit purposes (to avoid being shut down by government authorities)?

A.T.: It is our goal (and has been for months) to get legal legitimisation. Our organisation has been aggressively seeking FSA regulation here in the UK for Britcoin. Our hope is that when governments do come to look at Bitcoin, they will see a long running, honest, legal exchange with open books. By having something in the law books about Bitcoin, it sets a positive legal precedent in the future and puts us as the policy makers rather than a bunch of old 60 year banker types.

Our exchange complies with the UK Know Your Customer laws which ensures it's not being used for illicit activity. We keep detailed transaction records and run regular audit logs to look for missing funds.

But eventually, one would want to use BitCoins to pay for legal services. My question is; how do you get to that point? Why would a legitimate business accept a currency that is used almost exclusively for illegal means? What is the strategy to convince mainstream businesses that BitCoins have a purpose in the main web, as well?

A.T.: The illicit markets are a very small part of Bitcoin yet the most sensationalist. I can see how one would think Bitcoin is purely for illegal trade if I didn't know better.

Check out the list of merchants.

Full and open disclosure: how many bitcoins do you currently own?

A.T.: 32 BC. At one point I had 6000, but I'm a bad hoarder. Everytime Bitcoins would double (and I'd have $2k), I'd donate half my wealth to other free software developers. Then recently I was going to wait until I had $4k, but the price went down and I'm very bad at holding onto cash :)

But that doesn't bother me at all. We have our group of free software developers developing Bitcoin itself and other related projects. Funds are coming in and we're growing. The goal is to this as a sustainable operation paying developers working on Bitcoin fulltime.

What are the advantages of bitcoin?

One problem I see with bitcoin is it offers very little over what we currently have. If I want to perform an online transaction using my computer, unless I am buying something illegal, then there are already companies which offer products for me to use. If I want to make an anonymous purchase in person, I would easily use cash.

Bitcoin seems to suffer from a lack of portability, which makes me wonder, what "need" is bitcoin catering to? What do I do in my day-to-day life that bitcoin will help me do such that as some point, bitcoin becomes irreplaceable and achieves de facto permanency?

A.T.: Sending funds abroad is time consuming, expensive and difficult. Recently I tried sending funds to a Polish bank from the UK- the bank was closed and I waited until Monday. Requiring me to be in person at the bank, the woman was unable to enter the Polish L looking character into her terminal. I had to aquire an internet banking code to do it online. Waited 3 days, logged in and the internet banking form didn't work. In the end, I ended using a friend to aquire Bitcoins and use the Polish exchange bitomat (we never use Britcoin ourself).

I wanted to donate funds to the excellent Symphony of Science musician. I went to fill in the Paypal form, spent 10 mins signing up to an account, entering all my very personal details and my card was rejected. In the end I got him to accept Bitcoins and donated directly without paying fees to Paypal.

Sony recently was hacked. Millions of accounts were leaked. If they were using Bitcoins then the addresses people donated to would be known to the attacker. Not my private keys which enable said attacker to spend my cash.

With commerce, everything becomes cheaper. Bitcoin vastly reduces the overhead needed for fees. We no longer require staff sitting inside banks pressing numbers on a keyboard since the system is automatically backed by mathematics and cryptography, not laws and people.

    In regards to the question on illegal purchases with BTC he said:

    However, I really want people to understand one thing. The criminalization of Bitcoin would not stop the illegal activity that surrounds it.

    Well, I think you're jumping to conclusions if you thought that the idea is to halt the drug trade and prostitution rings by illegalizing BitCoins. I think the question was really asking how you feel about BitCoins enticing and extending illegal activities. Allow me to provide a real world example. A person I knew in a small town high school was making yearly trips to the nearest metropolis with his stash of cash, purchasing drugs from many sources and then driving back and dealing them. At some point this stash became $15,000 and on his last trip he made his first stop to pick up some mushrooms from a woman who had been compromised by police. As he pulled away, they picked him up and found some shrooms but also $14,000. Now, he went to jail for six months for drug possession but also the very large sum of money. They were able to prove that he was a dealer and was en route to make more purchases. If he had had BitCoins, he merely would have kept a wallet on his phone then transferred the cash to the woman and could have denied the whole transaction had taken place and was clueless about the shrooms in his car. Would they have been able to make anything stick?

    Criminalization would only stop people from enjoying the tremendous and fruitful benefits of such a system, it would hinder the social good.

    Not if the bad elements of society enjoy those "fruitful benefits" much more than the rest of society. All the old organized crime tactics like protection rackets suddenly become virtually untraceable when you can demand the money be sent to an anonymous BTC handle and then move it again. The flow of cash is a seriously important element in detecting and prosecuting crime and the anonymity of a currency destroys that. Corporate embezzlement becomes easier, drug dealing becomes easier, funding terrorism becomes easier, etc. Someone could steal my bank account information and pilfer money from me tomorrow but at least the bank would be able to trace it. Who traces the stolen wallet files? Sure the bank charges an overhead but they provide a service that is more secure than a mattress store.

    You seemingly sweep the bad under the carpet and talk about only the good. This is a double edged sword and it's insulting for you to deny it.

    We are aggressively advocating and promoting the legalization and regulation of the exchanges.

    You keep saying this but you fail to provide any details on how this will be done. When transactions are anonymous, how in the hell does this happen?

    Kings used to raise capital in order to wage wars. They required popular support before they were able to fund their wars. A common tool in modern day authoritarian regimes is currency manipulation in order to fund their wars of genocide (e.g Milosevic in the 90s). Bitcoin democratises governments.

    That is so bizarre, you're all for the regulation and legalization of exchanges ... are you seriously that daft that you don't think the government is going to tax that which it regulates? You can't eat your cake and have it too. How will we fund schools and libraries and roads if everyone's going through BTC? How will we even know that everyone's going through BTC? I cannot fathom how you expect this to work!

    I understand the good points of this experiment but I'm insulted by how quickly you try to pull the wool over everyone's eyes.

    The bitcoin effort needs the involvement of some economists with experience studying and understanding currencies, not just techies.

    Have you visited the Bitcoin forums? Quite a few economists there. Also, high profile magazines, such as The Economist [], have written about it from the point of view that Bitcoin is, in the very least, a highly interesting experiment. No mention of any built-in economic failures there.

    I don't understand the knee-jerk reaction that everyone here gets each time Bitcoin is mentioned. Almost every time it's accompanied misconceptions about USD being backed or otherwise thinking that something which is currently valuable (such as gold) is somehow guaranteed to always be that way.

    No, I don't have anything invested in Bitcoins, and I wouldn't want to store much value in it until it has stood the test of time, and the implementations are more robust. I was shocked when I found out the private keys are stored locally in an unencryped file - that's a f***ing travesty.

    This reads like it was written before the peak, the first crash, the Mt.Gox break-in and shutdown, and the second crash.

    A sizable fraction of the Bitcoins in existence are now trapped at Mt. Gox (formerly Magic, The Gathering Online Exchange) which turns out to be two guys in Tokyo who are in way over their heads. Mt. Gox is trying to re-establish who owns which account. Since the names, email addresses, and hashed passwords of their customers have been published, this is difficult. No date has been given when trapped funds will be available. One thing that's now clear: don't keep any significant funds in any of these "exchanges". They're not banks. They are unregulated non-bank depository institutions.

    Meanwhile, another exchange in Chile has taken up some of the slack, and the price of a Bitcoin has settled down around $14-15. At the beginning of June, it was around $8, and last week it spiked up to $30.

    It's worth bearing in mind that the entire Bitcoin economy has less volume than a typical US supermarket. There's not much you can actually buy. Unless the volatility drops below 1%/day, there won't be. Merchants can't set prices in Bitcoins yet without a big exchange rate risk.

    Bitcoins are a reasonable idea, but the Bitcoin financial ecosystem is far too flaky to take seriously.

Have you ever noticed that the people who are always trying to tell you `there's a time for work and a time for play' never find the time for play?
