Keeping your bitcoins safe - Academic Survey 2015
Dear fellow Bitcoiners, I am an MBA student and currently doing my master's thesis about bitcoin wallet safety. I have compiled a short survey of 12 questions for my thesis. The survey is completely anonymous. This survey is conducted purely for academic research purposes, it does not collect or require any personal information. The results will be published with my thesis. My goal is to make this thesis to be useful and informative for new bitcoiners. Especially on topics of how to keep bitcoins safe and to understand the differences between bitcoin wallets. Here is my survey link: http://goo.gl/forms/***** Thank you for participating in this survey, your feedback is very important for my research. Please feel free to contact me if you have any questions or comments about this survey: ********** Edited: Email
Bitcoin Survey Paper | Florian Tschorsch | May 26 2015
Florian Tschorsch on May 26 2015: Hi all, some time ago, we became interested in Bitcoin, but gathering relevant work and getting an overview was kind of painful. We took it as a sign that a survey paper on Bitcoin is desperately needed. Since then we observed the activities of the Bitcoin community. Recently we finished a technical report that is our attempt to contribute the lacking Bitcoin survey. Maybe it will be of interest to some of you: https://eprint.iacr.org/2015/464 Feedback is highly appreciated and would help to improve the quality of future revisions. Cheers, Florian. original: http://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-May/008256.html
Flatten the Curve. #18. The current cold war between China and America explained. And how China was behind the 2008 Wall Street financial Crash. World War 3 is coming.
China, the USA, and the Afghanistan war are linked. And in order to get here, we will start there. 9-11 happened. Most of the planet mistakenly understood terrorists had struck a blow against Freedom and Capitalism and Democracy. It was time to invade Afghanistan. Yet all of the terrorists were linked to Saudi Arabia and not Afghanistan, that didn't make sense either. Yet they invaded to find Bin Laden, an ex CIA asset against the Soviet Union and it's subjugation of Afghanistan. The land in the middle of nowhere in relation to North America and the West. It was barren. A backwater without any strategic importance or natural resources. Or was there? The survey for rare earth elements was only made possible by the 2001 U.S. invasion, with work beginning in 2004. Mirzad says the Russians had already done significant surveying work during their military occupation of the country in the 1980s. Mirzad also toes the line for U.S. corporations, arguing, “The Afghan government should not touch the mining business. We have to give enough information to potential investors.” Rare Earth Elements. The elements that make the information age possible. People could understand the First Gulf War and the Geopolitical importance of oil. That was easy, but it still didn't sound morally just to have a war for oil. It was too imperialist and so they fell in line and supported a war for Kuwaiti freedom instead, despite the obvious and public manipulation at the UN by Nayirah. This is some of her testimony to the Human Rights Council. While I was there, I saw the Iraqi soldiers come into the hospital with guns. They took the babies out of the incubators, took the incubators and left the children to die on the cold floor. It was horrifying. I could not help but think of my nephew who was born premature and might have died that day as well. After I left the hospital, some of my friends and I distributed flyers condemning the Iraqi invasion until we were warned we might be killed if the Iraqis saw us. The Iraqis have destroyed everything in Kuwait. They stripped the supermarkets of food, the pharmacies of medicine, the factories of medical supplies, ransacked their houses and tortured neighbors and friends. There was only one problem. She was the daughter of Saud Al-Sabah, the Kuwaiti ambassador to the United States. Furthermore, it was revealed that her testimony was organized as part of the Citizens for a Free Kuwait public relations campaign, which was run by the American public relations firm Hill & Knowlton for the Kuwaiti government (fun fact, Hill & Knowlton also have extensive ties with Bill Gates). So the public was aghast at her testimony and supported the war against the mainly Soviet backed, but also American supported and Soviet backed Saddam Hussein, in his war against Iran, after the Iranians refused to Ally with American interests after the Islamic Revolution. But that was oil, this was Rare Earth Elements. There was a reason the war was called, Operation Enduring Freedom. This natural resource was far more important in the long run. You couldn't have a security surveillance apparatus without it. And what was supposed to be a war on terror was in actuality a territorial occupation for resources. Sleeping Dragon China is next, and where there's smoke, there's fire. Let's go point form for clarity. • China entered the rare earth market in the mid-1980s, at a time when the US was the major producer. But China soon caught up and became the production leader for rare earths. Its heavily state-supported strategy was aimed at dominating the global rare earth industry. • 1989 Beijing’s Tiananmen Square spring. The U.S. government suspends military sales to Beijing and freezes relations. • 1997. Clinton secures the release of Wei and Tiananmen Square protester Wang Dan. Beijing deports both dissidents to the United States. (If you don't understand these two were CIA assets working in China, you need to accept that not everything will be published. America wouldn't care about two political activists, but why would care about two intelligence operatives). • March 1996. Taiwan’s First Free Presidential Vote. • May 1999. America "accidently" bombs the Belgrade Chinese Embassy. • 2002 Price competitiveness was hard for the USA to achieve due to low to non-existent Chinese environmental standards; as a result, the US finally stopped its rare earth production. • October 2000. U.S. President Bill Clinton signs the U.S.-China Relations Act. China's take over of the market share in rare earth elements starts to increase. • October 2001. Afghanistan war Enduring Freedom started to secure rare earth elements (Haven't you ever wondered how they could mobilize and invade so quickly? The military was already prepared). • 2005. China establishes a monopoly on global production by keeping mineral prices low and then panics markets by introducing export quotas to raise prices by limiting supply. • Rare Earth Elements. Prices go into the stratosphere (for example, dysprosium prices do a bitcoin, rocketing from $118/kg to $2,262/kg between 2008 and 2011). • In a September 2005. Deputy Secretary of State Robert B. Zoellick initiates a strategic dialogue with China. This was presented as dialog to acknowledge China's emergence as a Superpower (which China probably insisted on), but it was about rare earth elements market price. • October 2006. China allows North Korea to conduct its first nuclear test, China serves as a mediator to bring Pyongyang back to the negotiating table with the USA. • September 2006. American housing prices start to fall. (At some point after this, secret negotiations must have become increasingly hostile). • March 2007. China Increases Military Spending. U.S. Vice President Dick Cheney says China’s military buildup is “not consistent” with the country’s stated goal of a “peaceful rise.” • Mid-2005 and mid-2006. China bought between $100b and $250 billion of US housing debt between mid-2005 and mid-2006. This debt was bought using the same financial instruments that caused the financial collapse. • 2006. Housing prices started to fall for the first time in decades. • Mid-2006 and mid-2007. China likely added another $390b to its reserves. "At the same time, if China stopped buying -- especially now, when the private market is clogged up -- US financial markets would really seize up." Council on Foreign Relations-2007 August • February 27, 2007. Stock markets in China and the U.S. fell by the most since 2003. Investors leave the money market and flock to Government backed Treasury Bills. I've never seen it like this before,'' said Jim Galluzzo, who began trading short-maturity Treasuries 20 years ago and now trades bills at RBS Greenwich Capital in Greenwich, Connecticut.Bills right now are trading like dot-coms.'' We had clients asking to be pulled out of money market funds and wanting to get into Treasuries,'' said Henley Smith, fixed-income manager in New York at Castleton Partners, which oversees about $150 million in bonds.People are buying T-bills because you know exactly what's in it.'' • February 13, 2008. The Economic Stimulus Act of 2008 was enacted, which included a tax rebate. The total cost of this bill was projected at $152 billion for 2008. A December 2009 study found that only about one-third of the tax rebate was spent, providing only a modest amount of stimulus. • September 2008. China Becomes Largest U.S. Foreign Creditor at 600 billion dollars. • 2010. China’s market power peaked in when it reached a market share of around 97% of all rare earth mineral production. Outside of China, there were almost no other producers left. Outside of China, the US is the second largest consumer of rare earths in the world behind Japan. About 60% of US rare earth imports are used as catalysts for petroleum refining, making it the country’s major consumer of rare earths. The US military also depends on rare earths. Many of the most advanced US weapon systems, including smart bombs, unmanned drones, cruise missiles, laser targeting, radar systems and the Joint Strike Fighter programme rely on rare earths. Against this background, the US Department of Defense (DoD) stated that “reliable access to the necessary material is a bedrock requirement for DOD” • 2010. A trade dispute arose when the Chinese government reduced its export quotas by 40% in 2010, sending the rare earths prices in the markets outside China soaring. The government argued that the quotas were necessary to protect the environment. • August 2010. China Becomes World’s Second-Largest Economy. • November 2011. U.S. Secretary of State Hillary Clinton outlines a U.S. “pivot” to Asia. Clinton’s call for “increased investment—diplomatic, economic, strategic, and otherwise—in the Asia-Pacific region” is seen as a move to counter China’s growing clout. • December 2011. U.S. President Barack Obama announces the United States and eight other nations have reached an agreement on the Trans-Pacific Partnership later announces plans to deploy 2,500 marines in Australia, prompting criticism from Beijing. • November 2012. China’s New Leadership. Xi Jinping replaces Hu Jintao as president, Communist Party general secretary, and chairman of the Central Military Commission. Xi delivers a series of speeches on the “rejuvenation” of China. • June 2013. U.S. President Barack Obama hosts Chinese President Xi Jinping for a “shirt-sleeves summit” • May 19, 2014. A U.S. court indicts five Chinese hackers, allegedly with ties to China’s People’s Liberation Army, on charges of stealing trade technology from U.S. companies. • November 12, 2014. Joint Climate Announcement. Barack Obama and Chinese President Xi Jinping issue a joint statement on climate change, pledging to reduce carbon emissions. (which very conveniently allows the quotas to fall and save pride for Xi). • 2015. China drops the export quotas because in 2014, the WTO ruled against China. • May 30, 2015 U.S. Warns China Over South China Sea. (China is trying to expand it's buffer zone to build a defense for the coming war). • January 2016. The government to abolish the one-child policy, now allowing all families to have two children. • February 9, 2017. Trump Affirms One China Policy After Raising Doubts. • April 6 – 7, 2017. Trump Hosts Xi at Mar-a-Lago. Beijing and Washington to expand trade of products and services like beef, poultry, and electronic payments, though the countries do not address more contentious trade issues including aluminum, car parts, and steel. • November 2017. President Xi meets with President Trump in another high profile summit. • March 22, 2018. Trump Tariffs Target China. The White House alleges Chinese theft of U.S. technology and intellectual property. Coming on the heels of tariffs on steel and aluminum imports, the measures target goods including clothing, shoes, and electronics and restrict some Chinese investment in the United States. • July 6, 2018 U.S.-China Trade War Escalates. • September 2018. Modifications led to the exclusion of rare earths from the final list of products and they consequently were not subject to import tariffs imposed by the US government in September 2018. • October 4, 2018. Pence Speech Signals Hard-Line Approach. He condemns what he calls growing Chinese military aggression, especially in the South China Sea, criticizes increased censorship and religious persecution by the Chinese government, and accuses China of stealing American intellectual property and interfering in U.S. elections. • December 1, 2018. Canada Arrests Huawei Executive. • March 6, 2019. Huawei Sues the United States. • March 27 2019. India and the US signed an agreement to "strengthen bilateral security and civil nuclear cooperation" including the construction of six American nuclear reactors in India • May 10, 2019. Trade War Intensifies. • August 5, 2019. U.S. Labels China a Currency Manipulator. • November 27, 2019. Trump Signs Bill Supporting Hong Kong Protesters. Chinese officials condemn the move, impose sanctions on several U.S.-based organizations, and suspend U.S. warship visits to Hong Kong. • January 15, 2020. ‘Phase One’ Trade Deal Signed. But the agreement maintains most tariffs and does not mention the Chinese government’s extensive subsidies. Days before the signing, the United States dropped its designation of China as a currency manipulator. • January 31, 2020. Tensions Soar Amid Coronavirus Pandemic. • March 18, 2020. China Expels American Journalists. The Chinese government announces it will expel at least thirteen journalists from three U.S. newspapers—the New York Times, Wall Street Journal, and Washington Post—whose press credentials are set to expire in 2020. Beijing also demands that those outlets, as well as TIME and Voice of America, share information with the government about their operations in China. The Chinese Foreign Ministry says the moves are in response to the U.S. government’s decision earlier in the year to limit the number of Chinese journalists from five state-run media outlets in the United States to 100, down from 160, and designate those outlets as foreign missions. And here we are. You may have noticed the Rare Earth Elements and the inclusion of Environmental Standards. Yes these are key to understanding the Geopolitical reality and importance of these events. There's a reason the one child policy stopped. Troop additions. I believe our current political reality started at Tiananmen square. The protests were an American sponsored attempt at regime change after the failure to convince them to leave totalitarian communism and join a greater political framework. Do I have proof? Yes. China, as far as I'm concerned, was responsible for the 2008 economic crisis. The Rare Earth Elements were an attempt to weaken the States and strengthen themselves simultaneously. This stranglehold either forced America to trade with China, or the trade was an American Trojan horse to eventually collapse their economy and cause a revolution after Tiananmen Square failed. Does my second proposal sound far fetched? Didn't the economy just shut down in response to the epidemic? Aren't both sides blaming the other? At this POINT, the epidemic seems to be overstated doesn’t it? Don't the casualties tend to the elder demographic and those already weakened by a primary disease? Exactly the kinds who wouldn't fight in a war. Does this change some of my views on the possibility of upcoming catastrophes and reasons for certain events? No. This is Chess, and there are obvious moves in chess, hidden moves in chess, but the best moves involve peices which can be utilized in different ways if the board calls for it. Is all what it seems? No. I definitely changed a few previously held beliefs prior to today, and I would caution you in advance that you will find some previously held convictions challenged. After uncovering what I did today, I would also strongly suggest reading information cautiously. This is all merely a culmination of ending the cold war, and once I have events laid out, you will see it as well. At this moment, the end analysis is a war will start in the near future. This will be mainly for a few reasons, preemptive resource control for water and crops, population reduction can be achieved since we have too many people, not enough jobs, and upcoming resource scarcity. Did you notice my omission of rare earth elements? This is because of Afghanistan. I would wager China or Russia is somehow supporting the continued resistance through Iran. But events are now accelerating with China because the western collation has already begun to build up their mines and start production. Do you remember when Trump made a "joke" about buying Greenland? Yeah. It turns out that Greenland has one of the largest rare earth mineral deposits on the planet. Take care. Be safe.

Cryptocurrency exchanges process over $20 billion in trade volume per day. Most of the transactions are going through centralized exchanges, where the users need to fully trust them for managing their assests and transactions. However, the risk of trusting these centralized exchanges has also been seen. For example, QuadrigaCX, which was the largest cryptocurrency exchange in Canada, lost $19 million of their customers' assets . Decentralized Exchanges (DEXes) have been introduced to address this problem -- they allow traders to purchase and sell cryptocurrencies in a peer-to-peer manner, so no involvement of any trusted party is required. Atomic Swap is one of the promising technology for implementing a DEX. While it enables pure peer to peer trading, it also introduces problems such as unfairness and long confirmation latency. While existing work  has provided a solution towards a fair atomic swap protocol, the issue of long confirmation latency is inherent. Another promising direction is leveraging liquidity pools. With liquidity pools, pairs of assets are reserved for trading. For any pair of assets supported by the liquidity pool, traders can exchange their assets without any third party. As traders can only perform the transactions if there are reserved assets, one core problem is how to attract liquidity providers to provide liquidity by reserving assets. It is not difficult to see that incentive [3,4], which has been a key component of all permissionless blockchains, can be equipped to incentivize liqudity providers. However, flawed incentive designs will lead to attacks and other concerns [5-13]. There are two main types of incentive designs, namely "trans-fee mining" and "liquidity mining". They are different from the Proof-of-X mining in blockchains for reaching consensus (a detailed analysis can be found in the survey ). Rather, they are used to incentivise users to join the ecosystem. "Trans-fee mining" was proposed by FCoin in 2018 . With FCoin, each time a transaction is created, 100% of its transaction fee will be returned in FCoin token to the payer as a reward. This is one incentive design to encourage traders to join the system. However, as FCoin may have no value to the trader, FCoin also introduces extra reward to all coin holders -- 80% of the transaction fee in its native currency (such as ETH) will be distributed to all coin holders. So, traders are incentivized to join the system, becoming a holder of FCoin token, and obtaining a share of the transaction fee of every transaction in the FCoin ecosystem. While this had successful attracted traders, it is not sustainable. Rather than charging a trader to perform transactions, FCoin rewards traders. Profit-driven traders will create transactions at full speed to earn FCoin token and the share as a token holder. Indeed, the trading volume of FCoin was the top one among all exchange services, and the daily reward can be as high as 6000 BTC . However, once all coins are minted, then the system would lose liveness as there is not enough supply to be distributed. "Liquidity mining" aims at giving reward to the liquidity providers rather than the traders. There are different ways to implement liquidity mining. Compound  is a famous example of protocols deploying liquidity mining. With Compound, users become a liquidity provider by supply assets to a pool and obtain interests for its contribution (similar to depositing money into a bank). Liquidity providers first reserve some assets in the pool and obtain "cToken" of Compound which entitles the owner to an increasing quantity of the underlying asset. Users can use their "cToken" to borrow different assets available on the Compound and pay some interests to Compund. The borrowers may have some quick gains through the financial games . Both borrowers and liquidity providers can withdraw their asset by trading them back with "cToken". Oners of "cToken" can also manage the business direction and decisions of Compound through weighted voting. The potential concern here is that rich users might be able to take over the control of the system. Uniswap  is another popular DEX deploying liquidity mining. Uniswap incentivizes liquidity providers by giving them a share of the earned transaction fees. In particular, Uniswap changes each transaction a 0.3% fee, where 0.25% will be distributed to the liquidity providers, and 0.05% will go to the Uniswap account. One issue is how to incentivize traders. With Uniswap, traders are incentivized by the potential profit it can gain through the price difference between Uniswap and other exchanges. Uniswap price oracle is based on a constant function market makers [20,21], where the product of the number of reserved tokens is a constant. For example, if Uniswap has a pair of X token A and Y token B, then when a user using X' token A to buy Y' token B, the product of the reserved number of tokens should remain the same, i.e., XY = (X+X')(Y-Y'). The price of Uniswap (V1) is also defined in this way. This allows traders to speculate in the exchange market as the asset price on Uniswap is changed dynamically and is different from other exchanges. This, on the other hand, may have a security risk as the price can be easily manipulated. Uniswap (V2) fixed this problem by taking an accumulated price over a period of time . However, as speculation/manipulation becomes harder, the trading volume may decrease. MiniSwap  introduces a hybrid model (a mixture of "trans-fee mining" and "liquidity mining") to address the above issues. MiniSwap provides three types of rewards. For each trade with transaction fee f ETH in MiniSwap, a number of MiniSwap tokens (called MINI) worth 2f ETH will be minted. A (parameterized) portion of the tokens are given to the trader, and the rest are distribued to the liqudity providers. The transaction fee (f ETH) is used to exchange MINI in the liquidity pool. 50% of the obtained MINI will be distributed to all MINI holders, and the other 50% will be destroyed. In this way, both traders and liquidity providers are incentivized to join the ecosystem. Recall that with FCoin, there is a problem when all coins are minted. MiniSwap has an upper bound (of 500,000 tokens) on the number of tokens can be created every day, and this limit reduces every month until a point where the limit (18,000 tokens) remains unchanged. This guarantees the sustainability of the system as the mining process can last for 100 years. The parameterized ratio of tokens as the reward to the trader and liquidity provider can also strengthen sustainability. It enables the system to dynamically balance the incentive of different parties in the system to make it more sustainable. Overall, the MiniSwap hybrid model has taken the benefit of both "trans-fee mining" model and "liquidity mining" model, while eliminated the potential concerns. Formally defining and analyzing these models, e.g. through the game-theoretic approach , would be an interesting direction.

Benefits of Blockchain Technology in the Banking Industry
Link to original article: https://block.co/benefits-of-blockchain-technology-in-the-banking-industry/ The rapidly growing interest around blockchain is creating an increased amount of use cases across multiple industries, and a high demand for adoption by many governments. Banking, financial services, and insurance (BFSI) industry is predicted to be drastically transformed by this disruptive technology. According to Allied Market Research 2019, the blockchain value in the BFSI market reached $277.1 million in 2018 and is projected to reach $22.46 billion by 2026. Blockchain technology has the potential to solve the pain points of the current banking systems and operations including security, transparency, trust, privacy, programmability, and performance. What is Blockchain? Blockchain is the technology behind the Bitcoin cryptocurrency, that was proposed by Satoshi Nakamoto in 2008, as a response to the failing financial system during the crisis. It is often associated and confused with Bitcoin, but the scope of the technology is much wider. It is also important to differentiate between the Distributed Ledger Technology (DLT) and blockchain, as the terms often used interchangeably. All blockchains are DLT, but not all DLTs are blockchains. DLT is simply a decentralized database managed on a peer-to-peer basis. “Blockchain is a type of DLT, a subcategory of a more broad definition, much like how the word ‘car’ falls under the umbrella term ‘vehicles’ and ‘Satoshi Nakamoto’ falls under ‘geniuses’.” In essence, blockchain is a continuous sequential chain of records (‘blocks’) that are chronologically linked together with the aid of cryptography, to ensure immutability. These records are immutable, as any change to the information recorded in a particular block is stored in a new block. Moreover, the use of modern encryption algorithms enables the security of all the records from copying or editing by other users of the system. Blockchain can be programmed to record not only financial transactions as cryptocurrency but almost anything of value (Deloitte Insights, 2019). https://preview.redd.it/k76j8u5401751.png?width=940&format=png&auto=webp&s=e7f6573a230c816a112ae4bf561f3501c353ad32 How Blockchain Can Improve Banking Industry? The modern banking system is not perfect and commercial banks have not changed a lot to their servicing structure since the 1970s (Haycock & Richmond, 2015). Running a bank still requires large numbers of the workforce, reliance on quite outdated systems, bloated structures with high probabilities of human error, and manual work. There are several aspects, which could be improved by the application of blockchain technology in banking operations: 1) Security Enhancement In the UK the overall value of the financial fraud losses (e.g. payment cards, remote banking, cheques) equaled £844.8 million in 2018. The situation is even worse in the US — $170 billion average yearly losses in the financial sector. According to KPMG’s Global Banking Fraud Survey 2019 the total volume, number, and value of the fraudulent activities are drastically increasing every year. The nature of banking operations dictates the need for centralized systems, which proved to be vulnerable and subject to cyber and hack attacks. Now, the blockchain is immutable as it operates on the principles of decentralization and transparency, and all the network participants get an identical copy of the distributed ledger of transactions. Thus, if applied in banking, blockchain can increase the validity and security of the financial transactions, eliminate the need for third-party authentication, and solve the issue of a single point of failure and hacks. Moreover, since each transaction on the blockchain has its unique fingerprint (hash) it can be easily traced and verified. Such functionality makes blockchain a great tool to combat money laundering and reduce fraudulent or illegal transactions (Guo & Liang, 2016). 2) Improving Financial Transactions Efficiency As we mentioned previously, the utilization of obsolete mechanisms and operational systems slows down the performance of banking institutions and provides ground for human error, delays, and system failures. All these inefficiencies could be solved by applying blockchain technology. Take for example the time-consuming bilateral exchange. The process of data reconciliation needed for it could be simplified, as on the blockchain, it is inherently part of a transaction (IBM, 2016). Blockchain and its decentralized nature eliminate intermediaries in banking operations, which significantly cuts transaction costs and boosts efficiency (Cocco et al., 2017). Blockchain does not require intermediaries, enables cross-border transfers and micro-payments, while drastically decreasing operational costs. Such transactions in the traditional banking environment are expensive (from 1% of the amount), and constitute a huge expense on a global scale. In cryptocurrency networks, transfers may range from a few minutes down to milliseconds, and the transaction fees are decided by the market forces, meaning users have the option to set their transaction fees (Deloitte, 2017). 3) Workflow Simplification Blockchain can simplify the current complex workflow in banking institutions. As any operation can be traced, the ability to automate processes significantly reduces costs and the need for manual work. Moreover, it is impossible to make retroactive changes on the blockchain. This guarantees data immutability and excludes the human factor, thus the probability of error, data tampering, or even leakage. Using blockchain in banking operations will digitize and automate tons of manual work, greatly boost the productivity of the financial institutions and eliminate the probability of mistakes, delays, and errors. 4) Enhanced KYC & AML Some financial institutions find it difficult to deal with problems related to policies such as Anti-Money Laundering (AML) and Know Your Customer (KYC). Numerous organizations are not able to solve these problems, due to the rapidly escalating costs. The adoption of the blockchain technology will enable the creation of a system where all clients’ information may be stored safely, making the independent verification an easy process or even automated securely. In this way, both AML and KYC processes will become simpler and easier, as all involved organizations will share the same system and the information will be updated in real-time, perhaps through the use of Digital Identities. In addition to this, blockchain technology will assist the organizations to minimize their administrative costs and reduce the workload. https://preview.redd.it/200e0ap701751.png?width=600&format=png&auto=webp&s=6caaf26c53786c1341b7905ca33dd340f8929059 5) Smart Contracts Smart contracts are an innovative development of blockchain technology which enables for time and resources saving, as they do not require a third-party interaction. Traditional contracts do not differ a lot from smart contracts, however, their key benefit is that obligations are automatically enforced and cannot be avoided by anyone. When smart contracts are integrated with blockchain technology, we enjoy benefits such as security, automation, immutability, and transparency. The integration of smart contracts in the financial sector will provide opportunities for transparent auditing and real-time remittances. Traditional contracts are paper-based and require financial institutions to invest money in paperwork and maintain records. These records can be easily manipulated as they are on paper. Smart contracts offer bank tools for bookkeeping based on blockchain. Smart contracts have already been applied to the financial industry to gain greater automation. 6) Decentralized Finance Another application of blockchain is Decentralized Finance, also known as DeFi. This application is at an early stage but its disruptiveness enables millions of people across the world to have access to financial services. DeFi refers to decentralized applications, financial smart contracts, digital assets as well as protocols popular as DApps, which are built on public blockchains such as Ethereum and Bitcoin. The aim of DeFi is the creation of a decentralized financial system that will not depend on the traditional banking system. Decentralized Finance offers numerous benefits to the users as it eliminates middlemen, enables everyone who does not has access to financial services to enter the global economy as it is a permission-less technology, and enables innovation with the combination of DeFi products. Besides, the use of decentralized finance increases the symmetry of information and democratizes financial services in this sense. The evolution of DeFi over the years means that most people around the world are only limited by their imagination when considering how to gain benefits from the financial ecosystem. However, there are still many complexities that need addressing to further expand the full extent of the possibilities of DeFi. For more info, contactBlock.codirectly or email at [email protected].

AMA Recap of CEO and Co-founder of Chromia, Henrik Hjelte in the @binancenigeria Telegram group on 03/05/2020.
Author:Gamals Ahmed, CoinEx Business Ambassador ABSTRACT A Blockchain is a continuously growing record, called blocks, which are linked and secured using cryptography such as hashing. Each block contains a hash pointer as a link to the previous block, a timestamp and transaction data. Filecoin is a decentralized storage network that turns cloud storage into an algorithmic market. The market runs on a blockchain with a native protocol token (also called Filecoin), which miners earn by providing storage to clients. The first section of report is demonstrate the filecoin which is a decentralized storage system used to encrypt files that we need to share it through blockchain platform. The second section is explain briefly blockchain Proof of Concept (POC) which is a process of locate whether a Blockchain project idea can be feasible in a real-world situation, need of proof of concept and blockchain proof of concept stages. 1.Introduction Filecoin is a protocol token whose blockchain runs on a novel proof, called Proof-of-Space time, where blocks are created by miners that are storing data. Filecoin protocol provides a data storage and retrieval service via a network of independent storage providers that does not rely on a single coordinator, where: (1) clients pay to store and retrieve data, (2) Storage Miners earn tokens by offering storage (3) Retrieval Miners earn tokens by serving data. Filecoin is a decentralized storage network that turns cloud storage into an algorithmic market. The market runs on a blockchain with a native protocol token (also called Filecoin”), which miners earn by providing storage to clients. Conversely, clients spend Filecoin hiring miners to store or distribute data. As with Bitcoin, Filecoin miners compete to mine blocks with sizable rewards. Filecoin mining power is proportional to active storage, which directly provides a useful service to clients (unlike Bitcoin mining, whose usefulness is limited to maintaining blockchain consensus). This creates a powerful incentive for miners to amass as much storage as they can, and rent it out to clients. The protocol weaves these amassed resources into a self-healing storage network that anybody in the world can rely on. The network achieves robustness by replicating and dispersing content, while automatically detecting and repairing replica failures. Clients can select replication parameters to protect against different threat models. The protocol’s cloud storage network also provides security, as content is encrypted end-to-end at the client, while storage providers do not have access to decryption keys. Filecoin works as an incentive layer on top of IPFS , which can provide storage infrastructure for any data. It is especially useful for decentralizing data, building and running distributed applications, and implementing smart contracts . Filecoin based on IPFS proposes a completely decentralized distributed storage network where customers and storage miners request services and submit orders to the storage and retrieval markets. And the miner provides a service to view matching quotes to initiate a transaction. The protocol guarantees the integrity of data storage by copying proofs and space-time certificates. The Filecoin protocol writes the order book, token transactions, and integrity challenge response records to the blockchain. 1.1 Blockchain Blockchain is a characteristic data structure formed by combining data blocks in a chain order inchronological order, and cryptographically guarantees decentralized, non-tamperable, unforgeable distributed shared ledger system. Figure 1 Blockchain Structure 1.2 Elementary Components in Filecoin The Filecoin protocol builds upon four novel components :
Decentralized Storage Network (DSN): We provide an abstraction for network of independent storage providers to offer storage and retrieval services.
Novel Proofs-of-Storage: We present two novel Proofs-of-Storage,(1) Proof-of Replication allows storage providers to prove that data has been replicated to its own uniquely dedicated physical storage. Enforcing unique physical copies enables a verifier to check that a prover is not deduplicating multiple copies of the data into the same storage space, (2) Proof-of-Space time allows storage providers to prove they have stored some data throughout a specified amount of time.
Verifiable Markets: We model storage requests and retrieval requests as orders in two decentralized verifiable markets operated by the Filecoin network. Verifiable markets ensure that payments are performed when a service has been correctly provided. We present the Storage Market and the Retrieval Market where miners and clients can respectively submit storage and retrieval orders.
Useful Proof-of-Work: We show how to construct a useful Proof-of-Work based on Proof-of Space time that can be used in consensus protocols. Miners do not need to spend wasteful computation to mine blocks, but instead must store data in the network .
1.3 Filecoin: Lifecycle of a File In this section we mentioned the lifecycle for file in Filecoin, as follow:
Put: Clients send information about the file, storage duration, and a small amount of Filecoin to the Storage Market as a bid. Simultaneously, Miners submit asks, competing to offer low cost storage. Deals are made in the Storage Market, on the blockchain.
Send: The Client then sends the file to the Miner, and the Miner adds the file to a sector. The sectors are cryptographically sealed, with verification sent to the blockchain.
Manage: Miners continuously prove they are storing all sectors they agreed to store. The client’s payment is released in installments. Additional currency is minted over time and awarded to Miners as a block reward, proportional to the storage they provide.
Request: A Client requests a file with some payment in Filecoin to the Retrieval Market (off chain); the first Miner to send the file is paid. Eventually, the contract expires and the storage is once again free.
Figure 2 Filecoin Lifecycle of a File 1.4 Filecoin is Built with IPFS The Interplanetary File System (IPFS) is a next-generation protocol to make the Web faster, safer, decentralized, and permanent. Since the initial IPFS release in January 2015, it has gained strong traction in a variety of industries and organizations. Today, IPFS is a foundational technology for many applications in the blockchain industry. Over 5 billion files have been added to IPFS, spanning scientific data and papers, genetic research, video distribution & streaming, 3D modeling, legal documents, entire blockchains and their transactions, video games, and more. IPFS and Filecoin are complementary protocols, and the adoption of the underlying IPFS protocol is a leading indicator of market demand for a faster, safer, decentralized storage service . Some IPFS Users Figure(3) IPFS users 1.5 IPFS Open Source Community The IPFS Project is a large community of open source contributors driven to decentralize the web. The community is made up of thousands of developers and users who have been working together for several years, building valuable and widely used software tools. The same seasoned core developers of IPFS are also leading the design and development of Filecoin. The IPFS team has experience building ambitious sotware projects and coordinating thriving developer communities. A significant portion of the IPFS community plans to join the Filecoin network, building tools and applications on this new, exciting platform [ 7]. 2. PoC PROJECTS: 2.1 What is PoC? PoC is abbreviate of Project of Concept which is a process of determining whether a Block-chain project idea can be feasible in a real-world situation. This process is necessary to verify that the idea will function as envisioned. The best part about proof of concept blockchain meaning is that it will help you to get a clear idea of what you are doing before you even get started. Furthermore, the proof of concept in the blockchain niche isn’t for exploring the marketplace for ideas only. Moreover, you won’t determine the best way to start the production process. Instead, you’ll only work on your possible blockchain solution option and see whether it’s capable of being a reality or not. Developing a blockchain proof of concept would require an investment of time, money and resources. In reality, you’d need to get your hands on supporting technologies or even the physical components needed to get the perfect plan. Going through the process is necessary for enterprises to see whether their idea is visible before using all production level equipment for it. According to a recent Gartner survey, 66% of CIOs think that blockchain is here to disrupt the existing marketplaces. And many will spend more than $10 million on the experimentation of the technology. So, if you were confused with what is proof of concept blockchain, now you know just what it is . PoC is used to demonstrate the feasibility and practical potential of any blockchain project in any field such as Energy, Communication, Services, Insurance and Healthcare. A PoC can either be a prototype without any supporting code or any MVP (Minimum Viable Product) with bare feature set. A PoC is a prototype that is used for internal organization who can have a better understanding of a particular project. 2.3 Why Companies Need a Proof of Concept? Usually, the blockchain proof of concept is awfully popular among the startups in the market. However, proof of concept in blockchain can also be a great tool for the Enterprises as well. Mainly there are three points for needing it.
Test out the blockchain project before going for mass production.
Identify possible pain points that can make the project not useful.
Save an enormous amount of time and money.
Although anyone who comes up with a blockchain project idea will think that it will work, however, proof of concept in blockchain will test out your idea to ensure that you get the best version out of it, which will save up a lot of time and money in the process. Another major reason for you to use proof of concept for blockchain is to ensure that all the stakeholders love your idea and would be interested in investing in it. Whether you are just adding up a new type of feature in the existing blockchain solution or developing it from scratch blockchain proof of concept would let you take the fastest route possible. This relatively gives a different edge in the proof of concept blockchain meaning . 2.4 Proof of Concept Phases Its explain as follows: Figure (4) explains the steps of blockchain PoC Step-1: Finding the Proper Blockchain Application Sectors That Adds Value Let’s start with the first step of the theoretical build-up stage. Many of you don’t really know which application sectors are great for blockchain Proof of concept . That’s why we are outlining some major application sector where you can use your solution. These are: 1.Finance Let’s start with the financing sector. This sector is relatively popular among the blockchain community. Furthermore, there are many projects already that cover this sector and offer a lucrative solution for major issues. So, in that sense, this sector is quite competitive in case of blockchain PoC development. 2. Medical The medical sector is another major blockchain application sector at present. There are count-less scenarios where blockchain can truly shine. Hospitals have to deal with a lot of falsifying reports and counterfeit drugs. 3. Asset Management Maintaining asset in these times are relatively hard due to all the bad players in the market. Simple paper-based record keeping isn’t enough now. Moreover, due to political and other reasons, ownership management is at risk of becoming a corrupted sector. 4. Government Many governmental institutions are falling behind in the race of digitization. Moreover, every citizen needs a better infrastructure which will give them the security they need. In reality, the government sector is unable to reserve the citizen rights properly. 5. Identity Identity management is a big hassle when it comes to enterprises. Furthermore, many often impersonate other people’s identity and commit serious crimes. Even in trade financer, many companies have to deal with fake companies and fake documents. 6. IoT Internet of things is a wonderful sector for proof of concept in blockchain development. Furthermore, this sector is responsible for linking all your smart applications together. Moreover, the device to device connection in a secured platform is necessary. 7. Payments The payments sector is another awesome application point for your enterprise-grade solution. The blockchain system is more than capable of handling payments, and many of it also offer micro payments. Furthermore, it takes a really small amount of time to send money compared to the traditional banking system. Not to mention the reduction of fees in overseas payment. 8. Supply Chain Big enterprise needs to have their eyes and ears in every step of the supply chain process. Furthermore, any minor errors could end up in a million dollars of loss. Obviously, you would not want that. Tracking where the raw materials are coming from and whether your products are truly authentic or not is one of the major pain points. 9. Insurance The insurance industry is facing some serious problems regarding insurance claims and document authentication. Also, the enormous amount of paperwork that every single employee has to fill out is overly dreadful. Detecting fraud, managing all the documents in a secure environment is tough. So, if you introduce a blockchain framework that can solve all these issues would be a huge factor. However, the competition in this marketplace is a bit high; still, with proper blockchain proof of concept, it should be a great opportunity. Step-2: Defining the Product In the second stage of the theoretical build-up, you would need to think your blockchain Proof of concept just like any other product. Furthermore, you need to have a solid plan along with full support from all stakeholders. PoC Feature Requirements Define all the features that your enterprise blockchain solution needs. After deciding your blockchain application, you would probably have some idea on what features to add up. Step-3: Investigating the Technology After you’ve come up with the solid idea of what features to include and how to focus the road map, you would need to hand them off to the engineering team. Therefore, your team will then research the technology based on your requirements and come up with the best plat-form to develop it on.
Advice to make a successful Proof of Concept As we knew, a proof of concept is a project, and like any project it must be clearly defined. That means breaking down the process into these four steps in order to can manage it better.
Focus on a Specific Business Issue If you want to make the blockchain PoC framework a success, then you have to start with focusing your real-life problems. At the beginning of the theoretical build-up stage when you are looking for a popular sector of deployment, look for a specific issue. Furthermore, any problem that your idea can fix would be a big plus from the consumers’ end. Many blockchain proof of concept only focuses on the capabilities of the technology only. However, they just don’t resolve any new issues or even old issues.
Take Small Steps, Avoid Scope Creeps Another major thing that the enterprises face is the scope creeps. While choosing what features you might need for the blockchain proof of concept many go for too much from the start. However, making a flashier entrance in the market won’t mean 100% success. Further-more, get the ones that you can truly deliver, not the ones you aren’t capable of.
Connect All Ideas and Control Them You won’t be the only one coming up with all the ideas. As you already know you’d need to get yourself a good team that will back you up and helps you come up with a compact solution. However, not every single member of your team would agree with the same idea. Furthermore, they have different ideas and vision regarding the blockchain development too.
Construct a Thorough Plan Another hurdle in the way of proper proof of concept blockchain is the misinterpretation of the blockchain implementation challenges. Obviously, blockchain implementation isn’t an easy task. At the first stage, it might have many flaws that would end up in possible failure scenarios.
Test A Million Times After getting the design done, you’d need to go into the testing phase. However, the problem is many seem to enroll the MVP before properly testing it, which end up in failure. So, test out the MVP a lot of time before making it accessible to the end-users.
Collaborate With Other Parties Collaborating with other enterprises could help to take down the overall costing of the block-chain proof of concept. Furthermore, if you are a small to medium level enterprise than collaborating with other parties could help out with the production costing. It will solely depend on the feature or the type of blockchain PoC framework you want to work on.
The Right Amount of Staff The right amount of stuff is always necessary to pull off a blockchain proof of concept project. Furthermore, you would need to recruit staffs that have blockchain skills or have an intellectual concept of the technology. Get the necessary amount of stuff with blockchain skill set to perfect the Blockchain Proof of Concept..
3. Conclusion This report explain a distributed storage scheme based on blockchain technology( Filecoin), and introduces the system design in detail in first part , we have studied about blockchain technology related for Filecoin(decentralized storage network), Filecoin, a highly-anticipated decentralized storage network (under development), announced that there will be more delays before its Mainnet can be officially launched. Created by Protocol Labs, Filecoin has been developed using the InterPlanetary File System (IPFS), an established peer to peer data storage network. The Filecoin software will allow users to trade storage space in an open and decentralized market place.In the second part we mentioned a proof of concept (PoC), The Blockchain Proof of Concept is a demonstration to verify that certain concepts or theories have the potential for real-world application. PoC represents the evidence demonstrating that a project or product is feasible and worthy enough to justify the expenses needed to support and develop it. REFERENCES  Juan Benet.

Bitcoin faucets are websites or applications that offer you a small amount of bitcoin as a reward for making easy tasks. Depending on the selected faucet, users can earn coins for completing various tasks, such as viewing certain websites, watching ads, entering a captcha, or playing a game. by StealthEX At the beginning of the cryptocurrency’s existence, when the stakes were not so high, the creators of faucets gave 5 bitcoins for each claim — back then it was their way to promote digital money among newcomers. Now faucets operate with much smaller amounts and give out some part of the Bitcoin, which is measured in Satoshi(named after the creator of Bitcoin). Satoshi is the smallest possible fractional number of Bitcoin — one BTC is equal to 100 million Satoshi. If you have ever left a water tap not completely closed, you probably noticed that water was dripping into it, and if you put a bowl under it, sooner or later it will be filled. Even though one-time payments on faucets are scanty, many advise not to neglect the opportunity to earn on them, because, with the right approach, faucets can bring a tangible profit with a minimum of effort. There are plenty of sites offering free bitcoins. Unfortunately, most of them are not trustworthy, do not live long, or are simply overflowed with annoying flashing ads. However, there are some that work for many years, used by thousands of users and considered reliable. Here is the list of them:
This faucet is probably the most well-known one. It was created in 2013 on the territory of the British Virgin Islands. Payouts are not fixed and vary for each claim. You can get cryptocurrency every hour, and for each claim you get from 0.00000030 to 0.03 BTC. In addition to the faucet, Freebitcoin allows you to earn in other ways — save interest on your deposit, play the lottery, invite new users via referral links. It supports several withdrawal methods: you can set up automatic withdrawal every Sunday, slow withdrawal every 6–24 hours, or use the fastest instant withdrawal that takes 15 minutes. The last one, of course, has the highest fee.
Founded in 2015, the Moon Bitcoin has a certain user base and is considered by many to be one of the best faucets in existence. There are many appealing bonus offers. For example, the site gives you a reward for consistency — if you enter a captcha at least once every day, you will accumulate a bonus +1% to earnings daily. Like most other faucets, Moon Bitcoin offers a bonus for bringing new users. Earned funds are instantly transferred to the linked Coinpot wallet. The minimum withdrawal amount is 10,000 Satoshi if you agree to pay the fee. Or wait until it’s going to be over 50,000 Satoshi on your account and withdrawal money for free. It is worth saying that Coinpot has its own bonus program. For example, for one captcha entry, you get 3 Coinpot tokens that can also be converted to cryptocurrency. There are also Moon faucets for Litecoin, Dash, Bitcoin Cash and DogeCoin. All payments are concentrated in one Coinpot account.
Bonus Bitcoin is one of the oldest services and is considered one of the best bitcoin faucets. You can request a new portion of free coins every 15 minutes, getting an average of 10 Satoshi per claim. You can also gain more coins completing tasks in the offers and surveys section. Users who regularly stay active for a number of days receive an additional 5% of their daily rewards. The site also gives 50% of all fees of users you invited using referral links. Bonus Bitcoin accounts are also connected to Coinpot, a micro-earnings wallet that accumulates your payouts. The site also provides the opportunity to earn Litecoin and Dogecoin.
This is one more faucet associated with Coinpot wallet. Bitfun started its work in January 2017. In addition to the faucet itself, which allows you to request free Satoshi every 3 minutes, the site has a large number of browser games of various genres. Progress in these games gives you additional earnings. You can also earn coins by completing offers. As with Bonus Bitcoin, the user receives 50% of the fees of their referrals.
The service was launched in 2018 and has become known as one of the best free bitcoin generators. There are several ways to claim Satoshi. In addition to the faucet, you can also earn bitcoins by watching videos, clicking on ads, and playing browser games. Here you can make claims once every 12 hours and get a certain number of Coins to your account. Coins are the inner currency of this service, 10000 Coins worth 1$. It converted to Satoshi at the time of withdrawal. Rewards can be collected at FaucetHub, another web wallet for micropayments, in this case, the withdrawal limit is 35,000 Coins. For amounts over 100,000 Coins, withdrawals can be made directly to your bitcoin wallet. Or you can keep Coins at the site and earn 5% interest. Users can earn a loyalty bonus, by claiming rewards every day. Bringing another user via referral link gives you 25% of their claims and 10% of their offer earnings.
PentaFaucet is one of the oldest and most stable bitcoin faucets today. The main difference from similar websites is that the site uses double protection: captcha and anti-bot. You can collect from 5 to 25 Satoshi every 5 minutes. A reasonable amount of advertising and a simple interface make working with the faucet comfortable. The faucet does not allow you to earn money from games, surveys, and other sponsorship services. In addition to the main method, it offers only a referral program, giving 10% from earnings of each new user. Earned Satoshi are instantly transferred to the FaucetHub wallet. You can withdraw your funds from FaucetHub to your bitcoin wallet once a week on Sundays.
FireFaucet is a multi-currency automatic faucet, perhaps the best of its kind. This resource allows you to earn 9 cryptocurrencies at the same time, as well as instantly withdraw the accumulated funds to the Faucet Hub. The Auto Claim function allows for collecting currency automatically. You can change the number of currencies to get and the time between collections. FireFaucet affords many different ways to earn money: in addition to the faucet itself, there are also offers, a referral system that gives 20% from newcomer’s income, and browser mining. FireFaucet also has its own unique level system: getting XP for various actions on the site and raising their level, users receive a reward in Satoshi. As a pleasant addition, FireFaucet has a nice-looking design and does not use pop-up ads.
This bitcoin faucet does not require registration. All you need is the public address of your BTC wallet. Users can claim Satoshi every hour, getting from 5 to 1200 each time. At the moment DailyFreeBits is using the FaucetHub wallet we are already familiar with. The resource offers a referral reward. By inviting new users to the website, you can regularly receive 10% of their earnings. These are probably the best bitcoin faucets at this point. Do not expect that you will earn loads of money just using faucets, but it is with no doubt an interesting and easy way to get a certain portion of free Satoshi and learn how the cryptocurrency and various wallets work. Always be careful and study every site that is claimed to be a Bitcoin faucet with some scepticism. Always be critical of your choice and read reviews.

Bezos declined the offer without further comment. · In September 2018, Business Insider reported that Bezos was the only one of the top five billionaires in the world who had not signed the Giving Pledge, an initiative created by Bill Gates and Warren Buffett that encourage wealthy people to give away their wealth. “Percentage margins don't matter. What matters always is dollar margins: the actual dollar amount. Companies are valued not on their percentage margins, but on how many dollars they actually make, and a multiple of that.” “We have the resources to build room for a trillion humans in this solar system, and when we have a trillion humans, we'll have a thousand Einsteins and a thousand Mozarts. It will be a way more interesting place to live.” Jens Weidmann 1968 – Present Born: Germany Resides: Germany · German economist and president of the Deutsche Bundesbank. Chairman of the Board of the Bank for International Settlements. From 1997 to 1999, Weidmann worked at the International Monetary Fund. In 2006, he began serving as Head of Division IV (Economic and Financial Policy) in the Federal Chancellery. He was the chief negotiator of the Federal Republic of Germany for both the summits of the G8 and the G20. He was given the 2016 Medal for Extraordinary Merits for Bavaria in a United Europe. · Weidmann was involved in a series of major decisions in response to the financial crisis in Germany and Europe: preventing the meltdown of the bank Hypo Real Estate, guaranteeing German deposits and implementing a rescue programme for the banking system, piecing together two fiscal-stimulus programmes, and setting up the Greek bail-out package and the European Financial Stability Facility (EFSF). · In a 2011 speech, Weidmann criticized the errors and “many years of wrong developments” of the European Monetary Union (EMU) peripheral states, particularly the wasted opportunity represented by their “disproportionate investment in private home-building, high government spending or private consumption”. In May, 2012, Weidmann's stance was characterized by US economist and columnist Paul Krugman as amounting to wanting to destroy the Euro. In 2016, Weidmann dismissed deflation in light of the European Central Bank's current stimulus program, pointing out the healthy condition of the German economy and that the euro area is not that bad off. “I share the concerns regarding monetary policy that is too loose for too long. … As you know I have concerns about granting emergency liquidity on account of the fact that the banks are not doing everything to improve their liquidity situation.” Jerome Powell 1953 – Present Born: United States Resides: United States · Current Chair of the Federal Reserve, nominated by Trump. Powell has faced substantial and repeated criticism from Trump after his confirmation. The Senate Banking Committee approved Powell's nomination in a 22–1 vote, with Senator Elizabeth Warren casting the lone dissenting vote. · Powell briefly served as Under Secretary of the Treasury for Domestic Finance under George H. W. Bush in 1992. He has served as a member of the Federal Reserve Board of Governors since 2012. He is the first Chair of the Federal Reserve since 1987 not to hold a Ph.D. degree in Economics. · Powell has described the Fed's role as nonpartisan and apolitical. Trump has criticized Powell for not massively lowering federal interest rates and instituting quantitative easing. · The Bloomberg Intelligence Fed Spectrometer rated Powell as neutral (not dove nor hawk). Powell has been a skeptic of round 3 of quantitative easing, initiated in 2012, although he did vote in favor of implementation. · Powell stated that higher capital and liquidity requirements and stress tests have made the financial system safer and must be preserved. However, he also stated that the Volcker Rule should be re-written to exclude smaller banks. Powell supports ample amounts of private capital to support housing finance activities. “The Fed's organization reflects a long-standing desire in American history to ensure that power over our nation's monetary policy and financial system is not concentrated in a few hands, whether in Washington or in high finance or in any single group or constituency.” John Cochrane 1957 – Present Born: United States Resides: United States · Senior Fellow of the Hoover Institution at Stanford University and economist, specializing in financial economics and macroeconomics. · The central idea of Cochrane's research is that macroeconomics and finance should be linked, and a comprehensive theory needs to explain both 1.) how, given the observed prices and financial returns, households and firms decide on consumption, investment, and financing; and 2.) how, in equilibrium, prices and financial returns are determined by households and firms decisions. · Cochrane is the author of ‘Asset Pricing,’ a widely used textbook in graduate courses on asset pricing. According to his own words, the organizing principle of the book is that everything can be traced back to specializations of a single equation: the basic pricing equation. Cochrane received the TIAA-CREF Institute Paul A. Samuelson Award for this book. “Regulators and politicians aren’t nitwits. The libertarian argument that regulation is so dumb — which it surely is — misses the point that it is enacted by really smart people. The fact that the regulatory state is an ideal tool for the entrenchment of political power was surely not missed by its architects.” John Keynes(John Maynard Keynes, 1st Baron Keynes) 1883 – 1946 Born: England Died: England · British economist, whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles, and was one of the most influential economists of the 20th century. Widely considered the founder of modern macroeconomics, his ideas are the basis for the school of thought known as Keynesian economics, and its various offshoots. Keynes was a lifelong member of the Liberal Party, which until the 1920s had been one of the two main political parties in the United Kingdom. · During the 1930s Great Depression, Keynes challenged the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as long as workers were flexible in their wage demands. He argued that aggregate demand (total spending in the economy) determined the overall level of economic activity, and that inadequate aggregate demand could lead to prolonged periods of high unemployment. Keynes advocated the use of fiscal and monetary policies to mitigate the adverse effects of economic recessions and depressions. · Keynes's influence started to wane in the 1970s, his ideas challenged by those who disputed the ability of government to favorably regulate the business cycle with fiscal policy. However, the advent of the global financial crisis of 2007–2008 sparked a resurgence in Keynesian thought. Keynesian economics provided the theoretical underpinning for economic policies undertaken in response to the crisis by President Barack Obama of the United States, Prime Minister Gordon Brown of the United Kingdom, and other heads of governments. · Keynes was vice-chairman of the Marie Stopes Society which provided birth control education and campaigned against job discrimination against women and unequal pay. He was an outspoken critic of laws against homosexuality. Keynes thought that the pursuit of money for its own sake was a pathological condition, and that the proper aim of work is to provide leisure. He wanted shorter working hours and longer holidays for all. Keynes was ultimately a successful investor, building up a private fortune. “How can I accept the Communist doctrine, which sets up as its bible, above and beyond criticism, an obsolete textbook which I know not only to be scientifically erroneous but without interest or application to the modern world? How can I adopt a creed which, preferring the mud to the fish, exalts the boorish proletariat above the bourgeoisie and the intelligentsia, who with all their faults, are the quality of life and surely carry the seeds of all human achievement? Even if we need a religion, how can we find it in the turbid rubbish of the red bookshop? It is hard for an educated, decent, intelligent son of Western Europe to find his ideals here, unless he has first suffered some strange and horrid process of conversion which has changed all his values.” John Locke 1632 – 1704 Born: England Died: England · Known as the “Father of Liberalism,” Locke was an English philosopher and physician, widely regarded as one of the most influential of Enlightenment thinkers. His work greatly affected the development of epistemology and political philosophy. His writings influenced Voltaire and Jean-Jacques Rousseau, many Scottish Enlightenment thinkers, as well as the American revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the United States Declaration of Independence. · Locke's political theory was founded on social contract theory. Social contract arguments typically posit that individuals have consented, either explicitly or tacitly, to surrender some of their freedoms and submit to the authority (of the ruler, or to the decision of a majority) in exchange for protection of their remaining rights or maintenance of the social order. · Locke advocated for governmental separation of powers and believed that revolution is not only a right but an obligation in some circumstances. Locke was vehemently opposed to slavery, calling it “vile and miserable … directly opposite to the generous Temper and Courage of our Nation.” · Locke uses the word “property” in both broad and narrow senses. In a broad sense, it covers a wide range of human interests and aspirations; more narrowly, it refers to material goods. He argues that property is a natural right and it is derived from labour aand that the individual ownership of goods and property is justified by the labour exerted to produce those goods · According to Locke, unused property is wasteful and an offence against nature, but, with the introduction of “durable” goods, men could exchange their excessive perishable goods for goods that would last longer and thus not offend the natural law. In his view, the introduction of money marks the culmination of this process, making possible the unlimited accumulation of property without causing waste through spoilage. “The power of the legislative, being derived from the people by a positive voluntary grant and institution, can be no other than what that positive grant conveyed, which being only to make laws, and not to make legislators, the legislative can have no power to transfer their authority of making laws, and place it in other hands.” “No man in civil society can be exempted from the laws of it: for if any man may do what he thinks fit, and there be no appeal on earth, for redress or security against any harm he shall do; I ask, whether he be not perfectly still in the state of nature, and so can be no part or member of that civil society; unless any one will say, the state of nature and civil society are one and the same thing, which I have never yet found any one so great a patron of anarchy as to affirm.” John Mill(John Stuart Mill a.k.a. J. S. Mill) 1806 – 1873 Born: England Died: France · John Stuart Mill was arguably the most influential English speaking philosopher of the nineteenth century. He was a naturalist, a utilitarian, and a liberal, whose work explores the consequences of a thoroughgoing empiricist outlook. In doing so, he sought to combine the best of eighteenth-century Enlightenment thinking with newly emerging currents of nineteenth-century Romantic and historical philosophy. His most important works include System of Logic (1843), On Liberty (1859), Utilitarianism (1861) and An Examination of Sir William Hamilton’s Philosophy (1865). · Mill's conception of liberty justified the freedom of the individual in opposition to unlimited state and social control. A member of the Liberal Party and author of the early feminist work The Subjection of Women (in which he also condemned slavery), he was also the second Member of Parliament to call for women's suffrage after Henry Hunt in 1832. · Mill, an employee for the British East India Company from 1823 to 1858, argued in support of what he called a “benevolent despotism” with regard to the colonies. Mill argued that “To suppose that the same international customs, and the same rules of international morality, can obtain between one civilized nation and another, and between civilized nations and barbarians, is a grave error. ... To characterize any conduct whatever towards a barbarous people as a violation of the law of nations, only shows that he who so speaks has never considered the subject.” · John Stuart Mill believed in the philosophy of Utilitarianism, which he described as the principle that holds “that actions are right in the proportion as they tend to promote happiness [intended pleasure, and the absence of pain], wrong as they tend to produce the reverse of happiness [pain, and the privation of pleasure].” Mill asserts that even when we value virtues for selfish reasons we are in fact cherishing them as a part of our happiness. · Mill's early economic philosophy was one of free markets. However, he accepted interventions in the economy, such as a tax on alcohol, if there were sufficient utilitarian grounds. Mill originally believed that “equality of taxation” meant “equality of sacrifice” and that progressive taxation penalized those who worked harder and saved more. Given an equal tax rate regardless of income, Mill agreed that inheritance should be taxed. · His main objection of socialism was on that of what he saw its destruction of competition. According to Mill, a socialist society would only be attainable through the provision of basic education for all, promoting economic democracy instead of capitalism, in the manner of substituting capitalist businesses with worker cooperatives. · Mill's major work on political democracy defends two fundamental principles at slight odds with each other: extensive participation by citizens and enlightened competence of rulers. He believed that the incompetence of the masses could eventually be overcome if they were given a chance to take part in politics, especially at the local level. · Mill is one of the few political philosophers ever to serve in government as an elected official. In his three years in Parliament, he was more willing to compromise than the “radical” principles expressed in his writing would lead one to expect. “He who knows only his own side of the case knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side, if he does not so much as know what they are, he has no ground for preferring either opinion... Nor is it enough that he should hear the opinions of adversaries from his own teachers, presented as they state them, and accompanied by what they offer as refutations. He must be able to hear them from persons who actually believe them...he must know them in their most plausible and persuasive form.” “The only freedom which deserves the name is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it. Each is the proper guardian of his own health, whether bodily, or mental or spiritual. Mankind are greater gainers by suffering each other to live as seems good to themselves, than by compelling each to live as seems good to the rest.” John Rawls 1921 – 2002 Born: United States Died: United States · Liberal American moral and political philosopher who received both the Schock Prize for Logic and Philosophy and the National Humanities Medal in 1999, the latter presented by President Bill Clinton, who acclaimed Rawls for having “helped a whole generation of learned Americans revive their faith in democracy itself.” He is frequently cited by the courts of law in the United States and Canada. · Rawls's most discussed work is his theory of a just liberal society, called justice as fairness. Rawls first wrote about this theory in his book A Theory of Justice. Rawls spoke much about the desire for a well-ordered society; a society of free and equal persons cooperating on fair terms of social cooperation. · Rawls’s most important principle (the Liberty Principal) states that every individual has an equal right to basic liberties. Rawls believes that “personal property” constitutes a basic liberty, but an absolute right to unlimited private property is not. · Rawls's argument for his principles of social justice uses a thought experiment called the “original position”, in which people select what kind of society they would choose to live under if they did not know which social position they would personally occupy. “Justice is the first virtue of social institutions, as truth is of systems of thought. A theory however elegant and economical must be rejected or revised if it is untrue; likewise laws and institutions no matter how efficient and well-arranged must be reformed or abolished if they are unjust. Each person possesses an inviolability founded on justice that even the welfare of society as a whole cannot override. For this reason justice denies that the loss of freedom for some is made right by a greater good shared by others. It does not allow that the sacrifices imposed on a few are outweighed by the larger sum of advantages enjoyed by many. Therefore in a just society the liberties of equal citizenship are taken as settled; the rights secured by justice are not subject to political bargaining or to the calculus of social interests.” Joseph Nye 1937 – Present Born: United States Resides: United States · American political scientist and co-founder of the international relations theory of neoliberalism (a theory concerned first and foremost with absolute gains rather than relative gains to other states), developed in the 1977 book Power and Interdependence. He is noted for his notion of “smart power” (“the ability to combine hard and soft power into a successful strategy”), which became a popular phrase with the Clinton and Obama Administrations. · Secretary of State John Kerry appointed Nye to the Foreign Affairs Policy Board in 2014. In 2014, Nye was awarded the Order of the Rising Sun, Gold and Silver Star in recognition of his “contribution to the development of studies on Japan-U.S. security and to the promotion of the mutual understanding between Japan and the United States.” · From 1977 to 1979, Nye was Deputy to the Undersecretary of State for Security Assistance, Science, and Technology and chaired the National Security Council Group on Nonproliferation of Nuclear Weapons. In recognition of his service, he was awarded the State Department's Distinguished Honor Award in 1979. In 1993 and 1994, he was Chairman of the National Intelligence Council, which coordinates intelligence estimates for the President, and was awarded the Intelligence Community's Distinguished Service Medal. In the Clinton Administration from 1994 to 1995, Nye served as Assistant Secretary of Defense for International Security Affairs, and was awarded the Department's Distinguished Service Medal with Oak Leaf Cluster. Nye was considered by many to be the preferred choice for National Security Advisor in the 2004 presidential campaign of John Kerry. · Nye has been a member of the Harvard faculty since 1964. He is a fellow of the American Academy of Arts & Sciences and a foreign fellow of The British Academy. Nye is also a member of the American Academy of Diplomacy. The 2011 TRIP survey of over 1700 international relations scholars ranks Joe Nye as the sixth most influential scholar in the field of international relations in the past twenty years. He was also ranked as most influential in American foreign policy. In 2011, Foreign Policy magazine named him to its list of top global thinkers. In September 2014, Foreign Policy reported that the international relations scholars and policymakers both ranked Nye as one of the most influential scholars. “When you can get others to admire your ideals and to want what you want, you do not have to spend as much on sticks and carrots to move them in your direction. Seduction is always more effective than coercion, and many values like democracy, human rights, and individual opportunities are deeply seductive.” Karl Popper 1902 – 1994 Born: Austria-Hungary Died: England · Karl Popper is generally regarded as one of the greatest philosophers of science of the 20th century. He was a self-professed critical-rationalist, a dedicated opponent of all forms of scepticism, conventionalism, and relativism in science and in human affairs generally and a committed advocate and staunch defender of the ‘Open Society’. · In ‘The Open Society and Its Enemies’ and ‘The Poverty of Historicism’, Popper developed a critique of historicism and a defense of the “Open Society”. Popper considered historicism to be the theory that history develops inexorably and necessarily according to knowable general laws towards a determinate end. He argued that this view is the principal theoretical presupposition underpinning most forms of authoritarianism and totalitarianism. He argued that historicism is founded upon mistaken assumptions regarding the nature of scientific law and prediction. Since the growth of human knowledge is a causal factor in the evolution of human history, and since “no society can predict, scientifically, its own future states of knowledge”, it follows, he argued, that there can be no predictive science of human history. For Popper, metaphysical and historical indeterminism go hand in hand. · Popper is known for his vigorous defense of liberal democracy and the principles of social criticism that he believed made a flourishing open society possible. His political philosophy embraced ideas from major democratic political ideologies, including socialism/social democracy, libertarianism/classical liberalism and conservatism, and attempted to reconcile them. “Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them. In this formulation, I do not imply, for instance, that we should always suppress the utterance of intolerant philosophies; as long as we can counter them by rational argument and keep them in check by public opinion, suppression would certainly be most unwise. But we should claim the right to suppress them if necessary even by force; for it may easily turn out that they are not prepared to meet us on the level of rational argument, but begin by denouncing all argument; they may forbid their followers to listen to rational argument, because it is deceptive, and teach them to answer arguments by the use of their fists or pistols. We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant. We should claim that any movement preaching intolerance places itself outside the law, and we should consider incitement to intolerance and persecution as criminal, in the same way as we should consider incitement to murder, or to kidnapping, or to the revival of the slave trade, as criminal.” Lawrence Summers 1954 – Present Born: United States Resides: United States · American economist, former Vice President of Development Economics and Chief Economist of the World Bank, senior U.S. Treasury Department official throughout President Clinton's administration, Treasury Secretary 1999–2001, and former director of the National Economic Council for President Obama (2009–2010). Summers served as the 27th President of Harvard University from 2001 to 2006. Current professor and director of the Mossavar-Rahmani Center for Business and Government at Harvard's Kennedy School of Government. · As a researcher, Summers has made important contributions in many areas of economics, primarily public finance, labor economics, financial economics, and macroeconomics. Summers has also worked in international economics, economic demography, economic history and development economics.[ He received the John Bates Clark Medal in 1993 from the American Economic Association. In 1987, he was the first social scientist to win the Alan T. Waterman Award from the National Science Foundation. Summers is also a member of the National Academy of Sciences. · In 1983, at age 28, Summers became one of the youngest tenured professors in Harvard's history. In 2006, Summers resigned as Harvard's president in the wake of a no-confidence vote by Harvard faculty. Summers viewed his beliefs on why science and engineering had an under-representation of women to be a large part in the vote, saying, “There is a great deal of absurd political correctness. Now, I'm somebody who believes very strongly in diversity, who resists racism in all of its many incarnations, who thinks that there is a great deal that's unjust in American society that needs to be combated, but it seems to be that there is a kind of creeping totalitarianism in terms of what kind of ideas are acceptable and are debatable on college campuses.” · As the World Bank's Vice President of Development Economics and Chief Economist, Summers played a role in designing strategies to aid developing countries, worked on the bank's loan committee, guided the bank's research and statistics operations, and guided external training programs. The World Bank's official site reports that Summer's research included an “influential” report that demonstrated a very high return from investments in educating girls in developing nations. According to The Economist, Summers was “often at the centre of heated debates” about economic policy, to an extent exceptional for the history of the World Bank in recent decades. · In 1999 Summers endorsed the Gramm–Leach–Bliley Act which removed the separation between investment and commercial banks. In February 2009, Summers quoted John Maynard Keynes, saying “When circumstances change, I change my opinion”, reflecting both on the failures of Wall Street deregulation and his new leadership role in the government bailout.
