    Bitcoin and Tulip Mania

    Learning about Bitcoin forces you to think about money and value. Some people who look at Bitcoin come to the erroneous conclusion that it’s like tulip mania. Tulip mania took place in the 1600s in the Netherlands when the price of a rare or unique tulip bulb could exceed the price of a nice house. It is hard to fault these armchair Bitcoin analysts for making this comparison. After all, the spectacular rise in value of something that you can’t feel, touch, or see is outside the realm of their experience.


    Tulip bulbs have an interesting property that you can breed them. The folks buying the rare and unique tulip bulbs had the idea that if they purchased a valuable tulip bulb for breeding, they could make more, sell them, recoup their original investment and then continue to sell more tulip bulbs at pure profit. This seems like a pretty good idea on the face of it. Why didn’t it work? The answer lies in the geometric growth curve. I’m not a tulip expert, so I may offend the green thumbs that are reading this. Every year, you can dig up the tulip bulbs and where one was planted, you may have more than one bulb. This number is important. If the number was always exactly 1, and every tulip bulb was recovered, those tulips might still be worth the price of a home. If no new tulip bulbs were ever created, tulips would be very rare indeed . I googled it, and the number is more than 1, so you can increase your tulip bulb count holdings every year.


    I had a great Junior High School math teacher. A student asked him how to get rich. After a joke about not being a math teacher, he said, “Save fifteen percent of everything you make and invest it with compound interest and start early.” He taught us how to calculate compound interest, and since it was the Jimmy Carter days of high inflation, the compound interest rate was significant. That lesson stuck with me -- the power of compound interest, not the saving part. It turns out you need both to become rich.


    Let’s tiptoe back to the tulips. These tulips were breeding at a geometric rate with nothing but the requirements of land, water, and sunlight to limit the growth. The motivation was wealth and everyone wanted to sell their tulips to recoup the cost of their original tulip investment. The only possible mathematical outcome of this exponentially-increasing tulip production was that the tulips would lose value as too many of them came into existence. This was foreseeable. I don't have the stats on how many mathematicians invested in tulip bulbs, but I'd guess the answer is none.


    Bitcoin has a geometric curve too. The difference is that the multiplier for bitcoin is less than 1. It is, in fact 0.5. Roughly every four years, as determined by the original Bitcoin developer Satoshi Nakamoto, the rate at which new bitcoins will be generated will drop by half. An exponential curve with a multiplier less than 1 is known as exponential decay. The number of new bitcoins doesn’t explode like the rate of new tulip bulbs. New bitcoin production decreases and trends toward zero which is the exact opposite of tulip mania.


    To summarize, tulip mania was mathematically unsustainable because tulip production grew exponentially while tulip consumption was limited by the total human population size. Bitcoin has an exponential decay of the number of new units to be distributed among the holders of bitcoin. These are apples and oranges, or tulips and bitcoins. Not the same thing at all.


    The tulip bulb mania is closer to the quantitative easing policies of central banks. It is mathematically unsustainable. If I thought quantitative easing was a good idea, I’d use it myself and get one credit card to pay another, and then pay that with a cash advance from another credit card. If it worked long enough, I might even convince myself that it was great idea and that it saved me from the brink of financial ruin. I don't have the stats on how many mathematicians are invested in dollars, but I would hope none.

    Bitcoin Startups in Africa

    July 18th, 2014 by William

    Backup below (dhimmel):

    One frequently mentioned use case for cryptocurrency is as a conduit for international remittances. Currently, more than 200 million people live outside of their birth countries and these people send home over half a trillion dollars per year to relatives and friends. Money takes circuitous routes between wallets in Atlanta and hands in Accra (or the other way around). These routes are shaped by densely interlinked networks of national and international governments, laws, organizations, corporations, technologies, currencies and human relationships. This nexus of interrelated forces and actors constantly reshapes the channels through which people working abroad send money home. This column will draw attention to interesting developments in this space that have a bearing on cryptocurrency and other decentralized technologies.

    One company that is currently basking in the Bitcoin buzz is BitPesa, a startup seeking to enable BitCoin remittances to Kenya. BitPesa, which opened for service this month, charges a 3% fee to exchange BitCoin into Kenyan Shillings and deposit this money into a specified mobile money account.

    BitPesa works seamlessly with its namesake M-Pesa, the viral electronic cash network owned by Safaricom, Kenya’s leading cellular provider. M-Pesa is like a privatized currency—users deposit money with Safaricom, and this balance is linked to their phone number. Users can then beam these funds to other people’s phones or spend them at an ever-expanding network of M-Pesa merchants. Currently M-Pesa can be used to buy groceries, pay bills, hire cabs, and much more. In fact, some reports argue that 31% of Kenya’s GDP passes through the M-Pesa network. SafariCom is now East Africa’s most profitable company and has expanded into markets around the world, spawning competitors like Econet’s EcoCash based in Zimbabwe. 

    BitPesa claims that users around the world will be able to deposit BitCoin onto their platform and designate M-Pesa accounts in Kenya to receive Shillings. The conversion is done automatically so recipients in Kenya receive the money on their cellphones within minutes. Recipients do not require a BitCoin address or need to worry about market volatility. Senders, on the other hand, must find their own ways to buy BitCoin, although BitPesa has online tutorials about how to do this. Importantly, it should be noted that the fees associated with acquiring BitCoin are not included in BitPesa’s 3% calculation.

    BitPesa is not currently available in the United States, likely due to stringent American restrictions on international money transfer. It is, however, available in the United Kingdom where I will be traveling tomorrow. Is there a reader from Kenya who would be willing to help me test the BitPesa system? Please let me know ASAP in the comments section or in the forums and I will use the service to send you a small amount of BitCoin.

    BitPesa is a good example of a company using BitCoin to cash in on the business of sending money from “rich” countries to “poor” countries. Kitiwa, on the other hand, is a notable BitCoin startup based in Ghana that works the other way around. Kitiwa allows people in Accra to buy BitCoin with local currency in order to make online payments and send money abroad. This service is needed in Ghana because payment networks like Visa and PayPal routinely block people living there (and in other African countries) from using their systems.

    Kitiwa users begin by opening a BitCoin address, and the Kitiwa website contains a tutorial on using Blockchain.info to do this. Users then then pay for BitCoin with MPower Payments, a Ghanian mobile payments startup that allows people to fund purchase with their bank accounts, credit cards or mobile money accounts. Users can then use their BitCoin to pay for internet services like web hosting, send money to relatives living abroad or hire overseas consultants. The Kitiwa website even has a tutorial on how to use BitCoin to shop on Amazon.com through Gyft.

    These developments in Africa’s BitCoin ecosystem occur just as banks in the United States are pulling out of the remittance business. Laws aimed at money laundering and the financing of terrorism have increased costs for banks, which are responding by axing services. As Michael Corkery recently reported

    “JPMorgan Chase and Bank of America have scrapped low-cost services that allowed Mexican immigrants to send money to their families across the border. The Spanish bank BBVA is reportedly exploring the sale of its unit that wires money to Mexico and across Latin America. And in perhaps the deepest retrenchment by a bank, Citigroup’s Banamex USA unit has now closed many of its branches in Texas, California and Arizona that catered to Mexicans living in the United States and stopped most remittances to Mexico as it faces a federal investigation related to money laundering controls.”  

    In a recent op-ed the New York Times argued that banks’ move away from the remittance business will result in migrants paying higher fees to send money home, and that a possible solution would be for the World Bank to act as a centralized remittance clearinghouse. Many BitCoin enthusiasts are probably hoping that the opposite happens—that the banks' withdrawal will create openings that can be filled by BitCoin startups like BitPesa and Kitiwa. We will see what happens.

    Blockchain Bootstrapping Resource based Economy

    July 14th, 2014 by lainfinity

    ADAM's NOTE: PLEASE EDIT THIS COPY FOR THE TEST

    Summary

    • Differentiation of the blockchain from proof of work to proof of resource.
    • Advantages of a resource based economy.
    • Disadvantages of a consumption based economy.
    • Examples of resource based crypto-currencies.

    What is Proof of Resource?

     

    The Bitcoin network is built on Proof of Work, which is based on an algorithmic assymetry: valid hashes are computationally easy to verify but difficult to create. The vast processing power devoted to mining consumes electricity and therefore the bitcoin network is resource-backed.

    Downsides of the proof of work model such include the cost of maintaining the network and centralization of the asymmetric processing power. However instead I would like to discuss the upside which is long term impact of blockchain technology on the economy.

    Resource Based Economy vs Consumption Based Economy

     

    The concept of resource-based economics was developed by Jacque Fresco through his Venus Project in 1995.

    The Venus Project is an organization founded by Jacque Fresco that advocates for what it calls a resource-based economy. The goal is to combine Fresco’s versions of sustainable development, energy efficiency, natural resource management and advanced automation in a global socioeconomic system based on social cooperation and scientific methodology.

    Jacque Fresco’s work focuses only on natural resources of the planet such as minerals, natural gas and oil. However in the internet era, the scope of resources goes beyond natural resources of the planet. In a decentralized computer network resources include processing power, storage and network bandwidth. In any given community, resources include member skills, software development, availability of tools, and content produced.

    Since our current economy is based on the equilibrium between production and consumption, perpetual growth is only possible with perpetually increasing consumption. In other words, for growth to never reverse or cease, consumption must eventually become infinite. As inflation is baked into the very core of the growth pattern of this economy model, it is like a tornado that feeds itself anything on its path. Among this model's destructive consequences are peak oil, depletion of natural resources, and ever increasing pollution.

    Transition from division of labor which is Proof of Work by humans to Proof of Resource has already begun. Division of labor was advocated by Adam Smith in The Wealth of Nations. Thanks to the innovation of Blockchain, the technology is moving towards transforming centralization and corruption into decentralization, transparency and accountability at all levels.

    One of the main advantage of Proof of Resource model is that it is based on deflation rather than inflation. This is because the resources do not and cannot be inflated to infinity. Gold or any mineral mining are very good examples of this model. By implementing the Proof of Resource in a decentralized system we are making sure the resources are not controlled by few but managed by the people based on group consensus.The Blockchain enables the group consensus and empowers the people on a grass roots level.

    When we observe how nature operates, we can infer that the natural world conserves resources by reducing, reusing and recycling them. The planet powers itself by with plants that photosynthesize rather than combust fossil fuels. The planet’s ecology does not operate under the premise of inflation but is guided by the principle of conservation.

    Resource based Crypto-Currencies

    Proof of Resource model is implemented in some of the crypto currencies such as LTBcoin and SolarCoin. These are backed by resources such as community produced content and production of electricity through solar energy.

    Why is LTBcoin Proof of Resource based?

     

    Proof of Publication and Proof of Participation are the basis of LTBcoin. This model considers content produced by the community as a resource. The end users, who are the consumers, earn coins by participating in the community and enhancing the content through Proof of Participation. The distribution of LTBcoin for the next five years is as follows. 

    • 60% of LTBcoins will be distributed to members who publish content on the LTB Network 
    • 25% of LTBcoins will be distributed to members who are the end users 
    • 10% of LTBcoins will go towards the  maintenance of  the platform
    • 5% of LTBcoins will go towards administration 

    The main advantage of this model is that group concencus is required to control the discussion. This makes subtle censorship less likely than on sites like reddit or slashdot.

     

    Solarcoin

     

    SolarCoin is backed by two forms of proof of work. One is the traditional cryptographic proof of work associated with digital currency. Another proof of work is a 3rd party verified meter reading. SolarCoin is equitably distributed using both of these proofs of work as a means to reward solar energy generation.

    SolarCoin is the first renewable energy currency and also a resource based coin as it is backed by production of solar electricity. One solarcoin is rewarded to the producer of 1 megawatt of electricity.
