Research Paper Refutes Threat To Bitcoin Posed By Quantum Computing

Research Paper Refutes Threat To Bitcoin Posed By Quantum Computing

Research Paper Refutes Threat to Bitcoin Posed by Quantum Computing Research Paper Refutes Threat to Bitcoin Posed by Quantum Computing Jeffrey A. Tucker has penned an article to accompany a little-reported research paper that was published last October. The economics writer met with one of the papers authors recently to discuss the threat posed to the Bitcoin network by quantum computing. Quantum Computing Poses Little Real Threat to Bitcoin After meeting with Gavin K. Brennen, a researcher at the Centre for Quantum Technologies at the National University of Singapore, Tucker has concluded that quantum computing was not nearly the fatalistic threat that many tout it to be to cryptocurrencies. Quantum computers have often been cited as an irrefutable kill switch for Bitcoin. The idea is that quantum machines, capable of processing data hundreds of times faster than the most advanced computers today, could either brute force signatures in little time or solve proof-of-work algorithms fast enough to pose a threat to the security of the Bitcoin network. This would render Bitcoin and other similar cryptocurrencies entirely useless. Although Brennan et al. dont entirely refute this notion in their lengthy paper titled Quantum attacks on Bitcoin, and how to protect against them ,they do conclude that the threat is not nearly as fatalistic as many perceive it. In fact, given that quantum computing is still being developed, the authors believe that there is plenty of time to protect networks against it. In the companion article published by the American Institute for Economic Research (AIER) on Monday, Tucker praises the cryptocurrency communitys adeptness at problem solving: If there is a known problem, there are people working on solutions, with tremendous professional award Continue reading >>

Bitcoin Nonprofit Bitgive Announces New Project And Research Collaboration

Bitcoin Nonprofit Bitgive Announces New Project And Research Collaboration

Bitcoin Nonprofit BitGive Announces New Project and Research Collaboration May 31, 2018, 03:16:32 PM EDT By Nick Marinoff, Bitcoin Magazine BitGive - the globe's first bitcoin-based 501(c)(3) nonprofit - has joined hands with the University of Edinburgh to research and examine the effects of digital currencies on both national and international charities. Both organizations are seeking to develop a stronger, more organized system for allowing charities to accept virtual currency donations. BitGive previously made headlines in October 2017 when it launched its new GiveTrack platform, which uses blockchain technology to clarify and record digital asset donations to global charities. Individuals can trace their funds in real time, and see how their money is spent once an organization receives it. They are also informed of the charity's project results, creating direct engagement between the donor and the receiver. BitGive's founder Connie Gallippi explained in a statement: "It's been incredibly rewarding to see our GiveTrack platform gain unabating momentum. Throughout this process, we've discovered numerous opportunities, as well as challenges and barriers, that have helped shape the development of our platform and define crypto-philanthropy. Using this knowledge, in tandem with the bright minds at the University of Edinburgh, BitGive will be delving into how to overcome the roadblocks to effective crypto-philanthropy and establish how cryptocurrency can best be used to uplift and revolutionize the charitable sector." BitGive and the University of Edinburgh are seeking to uncover the challenges of using and converting cryptocurrencies in third-world countries. To do this, BitGive will analyze data collected from GiveTrack's implementations in nations like Indonesia, Keny Continue reading >>

Do not use URL shortening services: always submit the real link. Begging/asking for bitcoins is absolutely not allowed, no matter how badly you need the bitcoins. Only requests for donations to large, recognized charities are allowed, and only if there is good reason to believe that the person accepting bitcoins on behalf of the charity is trustworthy. News articles that do not contain the word "Bitcoin" are usually off-topic. This subreddit is not about general financial news. Submissions that are mostly about some other cryptocurrency belong elsewhere. For example, /r/CryptoCurrency is a good place to discuss all cryptocurrencies. Promotion of client software which attempts to alter the Bitcoin protocol without overwhelming consensus is not permitted. Trades should usually not be advertised here. For example, submissions like "Buying 100 BTC" or "Selling my computer for bitcoins" do not belong here. /r/Bitcoin is primarily for news and discussion. Please avoid repetition /r/bitcoin is a subreddit devoted to new information and discussion about Bitcoin and its ecosystem. New merchants are welcome to announce their services for Bitcoin, but after those have been announced they are no longer news and should not be re-posted. Aside from new merchant announcements, those interested in advertising to our audience should consider Reddit's self-serve advertising system .

Why Energy-sapping Bitcoin Mining Is Here Tostay

Why Energy-sapping Bitcoin Mining Is Here Tostay

Why energy-sapping bitcoin mining is here tostay Why energy-sapping bitcoin mining is here tostay Lead in Cryptocurrency and Blockchain, Cambridge Centre for Alternative Finance, Cambridge Judge Business School The Cambridge Centre for Alternative Finance has received funding from EY and VISA for conducting the 2017 Global Cryptocurrency Benchmarking Study and the 2017 Global Blockchain Benchmarking Study. The enormous use of energy needed to mine bitcoin and other cryptocurrencies is proving to be very contentious, but alternative methods pose far too much of a security risk. The recent warning that electricity use at bitcoin mining facilities in Iceland may exceed that consumed annually by the countrys homes, which could in turn lead to a potential energy shortage, was slightly alarmist in tone. But it showcases the huge amount of computational power needed to mine cryptocurrencies. Is the current cryptocurrency mining process really as wasteful and useless as critics say , and is it in need of a more efficient and cleaner system? The current mining process is indeed resource-intensive and wasteful, but there is no magic fix in sight. Many would argue that its precisely the useless nature of cryptocurrency mining that keeps the system secure. Cryptocurrencies are based on a globally distributed ledger shared among all participants in a decentralised network. This ledger is generally organised in the form of a cumbersome data structure the blockchain which consists of blocks of transactions that are cryptographically linked to each other. Most cryptocurrencies use a particular mechanism, dubbed proof-of-work (PoW), to determine which participant gets the right to add a new block of transactions to the blockchain. To prevent dishonest participants from creating multipl Continue reading >>

Cryptocurrency-based Funding: Bitcoins For Your Research?

Cryptocurrency-based Funding: Bitcoins For Your Research?

Home / Industry News / Cryptocurrency-based Funding: Bitcoins for Your Research? Cryptocurrency-based Funding: Bitcoins for Your Research? Scientists receive payments for their experiments through research grants. Research funding is critical to what scientists are able to do. This means that research funders have a lot of power. Without meaning to, they can influence what questions research institutions try to answer. After all, they can only work on what they have been given money to do. This process may skew how research is done. This is why independent funding is important. Researchers get money from the public and private sectors. In addition, the system of getting grant funding is not easy. Scientists spend a lot of time competing for grants given by research funders. Large companies or the military may fund academic research. Of course, each funder will have their own interests in research that benefits them. This means that funders decide what scientists will study. However, lack of funding for other areas can prevent worthwhile research from happening. Private institutions tend to have more resources than public ones. Private research institutions also tend to win more research grants. This creates a situation where private institutions can spend more on academic research. This makes them leaders in research which makes it even easier to attract more funding. This cycle makes it even more difficult for public institutions to win grants. Without grants, how will they improve their research output? Cryptocurrency is a possible independent source of research funding that could solve some of these problems. Cryptocurrencies might be the fastest growing type of asset in 2017. With the United States Treasuries almost at record lows, many investors are turning to alt Continue reading >>

Tiny Towns, Small States Bet On Bitcoin Even As Some Shun Its Miners

Tiny Towns, Small States Bet On Bitcoin Even As Some Shun Its Miners

The Pew Charitable Trusts Research & Analysis Stateline Tiny Towns, Small States Bet on Bitcoin Even as Some Shun Its Miners Tiny Towns, Small States Bet on Bitcoin Even as Some Shun Its Miners Workers look over racks of bitcoin data miners during construction of a bitcoin data center in Virginia Beach, Virginia. While some places are shunning mining companies, others are embracing any blockchain-related new businesses. Things have been kind of crazy in Massena, New York, since the bitcoin miners came to town. So crazy that Steve OShaughnessy, the new town supervisor, says he hasnt unpacked his office since he started his job in January. OShaughnessy says its a good thing, though. In the past decade, his town of about 13,000 on the St. Lawrence River has lost much of its main industry as a powertrain plant closed and an aluminum manufacturing plant downsized. But now, one and possibly two bitcoin mining companies are moving in, and they have promised to create dozens of jobs. Across the United States, bitcoin miners who set up computers to solve complex math programs and unlock new bitcoin are rushing to small towns and wide-open states with cheap rent, land or electricity. Many places are shunning the bitcoin mining companies, saying they suck up too much electricity without producing jobs. But places such as Massena are putting out the welcome mat not just for bitcoin miners, but for any and all cryptocurrency industries. The idea is to attract entrepreneurs who are developing new uses for blockchain technology, which records agreements and transactions on an open, online ledger. Bitcoin was the original blockchain technology, but enthusiasts envision a world in which the entire economy runs on the technology, allowing people to buy their homes, write their wills and Continue reading >>

Do the Rich Get Richer? An Empirical Analysis of the Bitcoin Transaction Network . Kondor D, Psfai M, Csabai I, Vattay G (2014). PLOS ONE, 9(5): e97205. The perception that the " rich get richer ", also sometimes referred to as the Matthew-effect after a biblical verse seems to be well established in society. From a modeling point of view it can thought as that someone who is already better established has more and better opportunities to gain more wealth, thus the total inequality increases. In the context of networks, this was the motivation of the preferential attachment model . In this case, instead of wealth, the participants of a network gain new connections with a rate proportional to their number of previous connections; this results in that already better connected nodes gain more links over time than others. The outcome of this process is the so called power-law distribution of degrees (the number of connections each node has), with a few nodes with very high number of connections ("rich club") and most nodes with only a relatively limited number of connections. In the case of Bitcoin, we can keep track of participants' (represented by their Bitcoin addresses) balance and also their network degree (i.e. how many distinct transaction partners they had previously). We can ask the question how these quantities change over time, and test if preferential attachment is present in either the network dynamics or wealth accumulation. Since we have the details of each transaction, we can analyze the statistics of new link formation, and test the hypothesis if nodes with larger wealth or degrees are favored as transaction recipients. We found that this is indeed true, preferential attachment holds for both network degrees and balances. Note that initiators of the transa Continue reading >>

University Research Project Analyzes Bitcoin Blockchain To Combat Sex Trade

University Research Project Analyzes Bitcoin Blockchain to Combat Sex Trade Researchers from several American universities are using artificial intelligence to examine the bitcoin blockchain to identify victims of sexual exploitation. The initiative plans to develop a freely available suite of tools that can assist authorities in tracking and identifying individuals working in the underground sex industry. Also Read: The Backpage Effect: Why the Sex Industry Thrives on Bitcoin The Project Will Analyze Online Ads and the Bitcoin Blockchain to Identify Participants in Illegal Sex Trade Researchers from the New York University Tandon School of Engineering, the University of California in Berkley, and the University of California in San Diego have teamed up to develop software designed to combat the sex trade through examining the bitcoin blockchain. The project seeks to develop machine-learning algorithms that can scan and identify patterns in sex ads, including the identification of illegal prostitution rings by identifying cryptocurrency wallets that are associated with multiple ads. UC Berkeley doctoral candidate, Rebecca Portnoff, has had significant involvement in the bitcoin blockchain analysis project. Portnoff stated that the technology weve built finds connections between ads. Is the pimp behind that post for Backpage also behind this post in Craigslist? Is he the same man who keeps receiving Bitcoin for trafficked girls? Questions like these are answerable only through more sophisticated technological tools exactly what weve built in this work that link ads together using payment mechanisms and the language in the ads themselves. Portnoff also stated where previously you might have five different phone numbers that you had no idea were connected, when you can se Continue reading >>

Researchers Find That One Person Likely Drove Bitcoin From $150 To $1,000

Researchers Find That One Person Likely Drove Bitcoin From $150 To $1,000

Researchers Neil Gandal, JT Hamrick, Tyler Moore, and Tali Oberman have written a fascinating paper on Bitcoin price manipulation. Entitled Price Manipulation in the Bitcoin Ecosystem and appearing in the recent issue of the Journal of Monetary Economics the paper describes to what degree the Bitcoin ecosystem is controlled by bad actors. To many its been obvious that the Bitcoin markets are, at the very least, being manipulated by one or two big players. This paper identifies and analyzes the impact of suspicious trading activity on the Mt. Gox Bitcoin currency exchange, in which approximately 600,000 bitcoins (BTC) valued at $188 million were fraudulently acquired, the researchers wrote. During both periods, the USD-BTC exchange rate rose by an average of four percent on days when suspicious trades took place, compared to a slight decline on days without suspicious activity. Based on rigorous analysis with extensive robustness checks, the paper demonstrates that the suspicious trading activity likely caused the unprecedented spike in the USD-BTC exchange rate in late 2013, when the rate jumped from around $150 to more than $1,000 in two months. The team found that many instances of price manipulation happened simply because the market was very thin for various cryptocurrencies including early Bitcoin. Despite the huge increase in market capitalization, similar to the bitcoin market in 2013 (the period examined), markets for these other cryptocurrencies are very thin. The number of cryptocurrencies has increased from approximately 80 during the period examined to 843 today! Many of these markets are thin and subject to price manipulation. The manipulation happened primarily via two bots, Markus and Willy, that seemed to be performing valid trades but did not actually Continue reading >>

Is There Any Academic Research On Bitcoin?

Is There Any Academic Research On Bitcoin?

Is there any academic research on Bitcoin? Economic Aspects of Bitcoin and Other Decentralized Public-Ledger Currency Platforms It's a long one so I'll break down the 2 most interesting arguments. 1) The author in the paper above (David Evans) argues that decentralization is in no way inherently better than centralization (using android vs apple as a comparison). However, my latest obsession is Maidsafe: The New Decentralized Internet . The CEO of Maidsafe (and all around brilliant dude - David Irvine) argues that the future will be marked by a movement towards greater and greater decentralization of systems, and in fact - bitcoin does not go far enough because bitcoin is centralized around the public ledger (block chain): Bitcoin blockchain is not a thing, it's a design pattern "The blockchain is currently a distributed centralised data structure [around the block chain] and this is important. What I mean is that the blockchain is not decentralised. Decentralisation that is partial in my mind is only distributed. The further we can decentralise then the more robust our systems will become. Its the human psyche to just build on the first bit of a system like this. The systems just now like MasterCoin , Ethereum etc are great, do not get me wrong. We need to keep innovating for sure. We must, though, extend what bitcoin has started and that means we must continue to decentralise information systems at their core as well as extending them where its seemingly obvious, as in the earlier examples. Its the reliance on the only blockchain that concerns me. These projects can exist without doing that, if we get it right." So is decentralization inherently better? My guess is that there are very few absolutes in this world. BUT I will say that *smart* decentralized systems are Continue reading >>

Don Tapscott: Ten 2018 Predictions From The Co-founder Of The Blockchain Research Institute Quartz

Don Tapscott: Ten 2018 Predictions From The Co-founder Of The Blockchain Research Institute Quartz

A year ago, Alex Tapscott (my co-author of Blockchain Revolution) and I made some predictions for 2017. At the end of the year we compared those predictions to what had actually occurred. Overall they stood up well. Notably we said: Bitcoin will hit $2,000 (thats right: one bitcoin will be worth $2,000). Ethereum will not collapse, post-DAO, but will become a dominant platform for new apps and new business models. We were ridiculed by some for forecasting that bitcoin would nearly triple in value. You guys are nuts, was a popular tweet. Of course, only in the wild world of cryptocurrencies can you set a one-year price target implying a near 200% return, and miss the mark by a factor of nearly 10! As for ethereum, the fork happened and ethereum kept on chugging away, became the de-facto platform for the ICO ( initial coin offering ) boom that launched a thousand Dapps (distributed applications), from distributed file storage and prediction markets to collectible kittens. 2017 was a year when cryptocurrency markets dominated the public imagination. While some of us grew excited by the explosion of new applications, platforms and technologies being launched, many others were simply happy to ride the wave of higher prices. Indeed, the value of these assets grew from $15 billion to $500 billion, one of the great bull markets of our time. Is this justified? Valuations today reflect tomorrows valueand tomorrows value could be significant and revolutionary. So, taking the market as a whole as the best representation for the future value of blockchain technology, todays value could be argued to be conservative. However, its hard to look at the dizzying price escalation of virtually every cryptoasset, and the euphoria driving the market ever higher, and not feel some vertigo-ind Continue reading >>

[security Research] Observing Bitcoin Nodes On The Public Internet

[security Research] Observing Bitcoin Nodes On The Public Internet

In an effort to start exploring blockchain technologies, Rapid7 Labs is pleased to release a paper titled, Off the Chain: Observing Bitcoin Nodes on the Public Internet. In this paper we combine intelligence from Project Heisenberg, our global honeypot network, and Project Sonar , our Internet scanning project with data from the Bitnodes Project, which aims to study the membership of the Bitcoin peer-to-peer network, and offer a variety of our observations. Since we began monitoring the Bitcoin network in August 2017, we observed 11,000 to 15,000 unique nodes participating in the network in any given day, and over 144,000 unique nodes since the observations began. Germany, China and the United States dominate the network. Our honeypots are not advertised or published, so any interaction with them is suspect. In this timeframe, Project Heisenberg observed interactions on our honeypots from over 900 unique nodes known to be participating in the Bitcoin network. Investigations into these interactions showed familiar patterns. Port scans and active reconnaissance with tools like Nmap were rampant, as was repeated attempted exploitation of MS17-010, largely from China. Who are the perpetrators of these attacks against our honeypots? Are the legitimate owners of these Bitcoin nodes actively attacking other nodes on the public Internet? Are these systems that have been compromised and are now being used to sling exploits and mine bitcoin? We may never know, but we offer several possible explanations along with our research. Join the block(chain) party. Check out the research report now. Continue reading >>
