1  Bitcoin / Press / [2018-03-21] Bitcoin Will Be World’s Leading Currency in 10 Years: Square CEO Ja on: March 21, 2018, 11:53:23 PM

One of Silicon Valley’s most revered entrepreneurs is going all in on Bitcoin.

Square CEO Jack Dorsey, who is in London this week promoting the digital payments firm, told The Times that he believes Bitcoin could become the world’s leading currency within a decade — or perhaps even sooner.

“The world ultimately will have a single currency, the internet will have a single currency. I personally believe that it will be bitcoin,” Dorsey said, adding that it would occur “probably over ten years, but it could go faster”.

As CCN reported, Square has added support for simple Bitcoin trading into the firm’s popular Cash App, and Dorsey has said that the company intends to add more Bitcoin-related functionality in the future.

This has led to speculation that Square may begin handling Bitcoin payments in its merchant payment processing software or perhaps even launch a full-fledged cryptocurrency exchange.

Dorsey — who also leads social media giant Twitter — conceded that Bitcoin in its present state of development is not an “effective currency,” citing slow confirmation times and high transaction fees (although fees are currently at a relative low point). Nevertheless, he expressed optimism about technologies that will make Bitcoin payments more user-friendly and efficient in the near future.

“It’s slow and it’s costly, but as more and more people have it, those things go away. There are newer technologies that build off of blockchain and make it more approachable,” he said, it “does not have the capabilities right now to become an effective currency”.

One of those technologies, presumably, is the Lightning Network (LN), a second-layer scaling solution that allows users to open off-blockchain payment channels and execute near-instant transactions with virtually no fees.

Dorsey, notably, recently invested in Lightning Labs one of the leading development teams focused on programming LN software. Earlier this month, Lightning Labs released lnd 0.4-beta, which is the first LN implementation to receive a beta release.

2  Bitcoin / Press / [2018-03-21] The EU Won’t Wait for Global Agreement on Cryptocurrencies: Spain’s on: March 21, 2018, 11:42:33 PM

During the G20 summit, the Spanish Minister of Economy, Industry and Competitiveness, Román Escolano Olivares, revealed that he doesn’t see cryptocurrencies as a threat to the global financial system and that the European Union (EU) may not wait for a globally coordinated effort to regulate cryptos.

Speaking on the sidelines of the ongoing summit, the minister pointed to two fundamental issues when it comes to cryptocurrencies – which he prefers to call crypto-assets – which are consumer protection, and their use in illicit activities.

Regarding cryptocurrencies, Olivares stated (roughly translated):

“The general agreement we have reached, is that right now we cannot think that crypto-assets are a risk to global financial stability, but it’s a subject we need to actively monitor.”

Olivares went on to state that consumer protection is an issue and that the Spanish Securities Commission (CNMV) and the country’s central bank have issued statements advising investors to tread carefully.

In addition, he pointed out that it’s important to address the role cryptocurrencies can have in crime and terrorist financing. Per his words, “it is very important that there are clear rules to prevent this kind of activity from developing,” thanks to the anonymity provided by various cryptocurrencies.

He added:


“In this way the FATF [Financial Action Task Force], which is an international body that regulates these activities, has a very clear position in which it is necessary to monitor and propose legislative norms around the world to prevent these activities.”

The minister’s position seemingly reinforces the views of the world’s economic leaders. As covered by CCN, the G20 communique showed “crypto-assets” is a preferred term, and that cryptocurrencies raise issues when it comes to investor protection, tax evasion, market integrity, money laundering, and terrorism financing.

The document goes on to state regulation recommendations are coming in July 2018. These will presumably allow for the development of the digital economy and its technology, while hindering their use for criminal activities.

Notably, Olivares pointed out that the European Union will not wait for a global agreement on cryptocurrencies. The minister revealed that the new digital economy should play its role in the “financing of public goods, the welfare system, and collective needs,” and not just leave it to the “so-called old economy.” He concluded:

“Our position is that we welcome the OECD proposals that have been presented here and we are ready to move forward. Tomorrow (March 21) the European Comission will propose a directive on how this new economy can participate in the financing of public accounts. Spain immediately joins the statements of other European colleagues and we want to move forward without the need to wait for a global agreement. There are huge income distribution problems and the new digital economy can greatly help countries in combating this problem. “

3  Bitcoin / Press / [2018-03-21] 15-Year-Old Hacks Hardware Crypto Wallet Ledger on: March 21, 2018, 11:30:54 PM

Hardware wallet Ledger Nano S had a break in – teenage security expert, Saleem Rashid, found an issue with the “tamper-free” wallet. The story began on Nov. 2017, when Rashid reported a flaw to Ledger CTO, Nicolas Bacca, which could allow attackers to steal funds from wallet users.

Rashid had observed that the microcontroller employed in the wallet was not secure. While it allowed the use of buttons and displays to input data, it was connected as a proxy to the Secure Element (SE). The latter contained private keys which meant that a hacker could trick the SE in different ways. Here’s how: retailers and resellers could change microcontroller’s firmware which, now compromised, could verify its ‘identity’ to the SE. He further explained that the attacker could control the user interface and use their malicious code to set randomness to zero and add a recovery seed of their own choice. Rashid chose the word ‘abandon’ to prove his point in an uploaded video. Now that the attacker had the mnemonic phrase, they could get the private keys easily.

After Rashid sent the research to Ledger, he saw that the flaw wasn’t taken seriously by the team. However, they did publish a firmware update on Mar. 6, which was heavily criticized by Rashid. He posted his opinions on Twitter, since he believed that the team should either have posted it as a critical update or disguised it so that hackers didn’t get time to use this trick.

Panic spread among users, who took to Reddit to discuss their next move. Eric Larchevêque, Ledger’s CEO, replied to one such post saying it was “a massive FUD”, and that Rashid was trying to bring attention to himself, when the problem was clearly not high-priority. “Saleem got visibly upset when we didn’t communicate as “critical security update” and decided to share his opinion on the subject,” wrote Larchevêque.

On Mar. 20, Ledger published another update that explained three problems discovered by bounty program researchers: Timothée Isnard, Saleem Rashid and Sergei Volokitin. Interestingly, Rashid denied this statement because signing Ledger’s Bounty Program Agreement would disallow him for publishing a technical report, which he clearly did on the very same day. As for the new updates, Rashid explained that he wasn’t allowed to receive the ‘release candidate’ by the company, but he believed that the new fixes were not completely free from hacker attacks.

“Is it truly possible to use a combination of timing and “difficult to compress” firmware to achieve security in this model?”, wrote Rashid. He received support from cryptographer Matthew Green, who explained in a lengthy Twitter thread how the teenager was able to break through Ledger’s secure tactic.

The teenager, who lives in U.K., previously uncovered a problem in cryptocurrency hardware wallet TREZOR One. The issue was resolved with a healthy communication between both parties. SatoshiLabs CEO, Marek Palatinus, even praised Rashid for his work, “His out-of-the-box thinking and creative approach help us to make an even more secure product.”

4  Local / Bitcoin Haberleri / Rusya’nın Kripto Para Birimlerini Düzenleyen Yasa Tasarısı Duma’da on: March 21, 2018, 11:23:37 PM

Rusya’da kripto paraları düzenlemeyi amaçlayan “Dijital Finansal Varlıklar” yasa tasarısı, Salı günü Duma’ya resmen sunuldu. Maliye Bakanı Yardımcısı Alexei Moiseev’e göre tasarıyla beraber Merkez Bankası ve Maliye Bakanlığı arasındaki anlaşmazlıklar çözüldü.

Yasalar ICO’ları ve Kripto Para Madenciliğini Düzenleyecek

20 Mart Salı günü Duma’nın resmi sitesinde yayımlanan, kripto paraları, ICO’ları ve madenciliği düzenleyecek olan tasarı Rus parlamentosuna resmen girmiş oldu.

Yapılan bir açıklamaya göre yasa tasarısı, dijital finansal teknolojiler kullanılarak oluşturulan finansal varlıkların yasallığını tanımlıyor. Tasarı ayrıca “Blockchain” uygulamasını da içeriyor. Bunun yanında tasarı, token’ler kullanarak tüzel kişilerin ve bireysel girişimcilerin yatırımlarını çekmek için şartlar koyuyor. Token ise “dijital finansal varlık türü” olarak tanımlanıyor.

Tasarı aynı zamanda ICO’lar için yasal dayanak ve token’ler için sıkı bir prosedür belirliyor. Yasa tasarısına göre token’lerin piyasaya sürülmesi “halka arz” şeklinde olmalı. Eğer yasa tasarısı mevcut haliyle kabul edilirse, token satışı yapan kişi ya da firmalar, ICO’lar hakkında bazı bilgileri açıklamak zorunda kalıyor.

Yasa tasarısında, “vasıfsız yatırımcılar” olarak adlandırılan girişimcileri korumak için de bir madde bulunuyor. Bu maddeye göre, Rusya Merkez Bankası, bu tür girişimcilerin alabileceği token sayısını sınırlama yetkisine sahip.

Tasarı, kripto para madenciliğine yasal bir statü kazandırıyor. Madencilik, “kripto para ödemesi yapılabilmesi için kripto para birimi oluşturulmasını amaçlayan faaliyet” olarak tanımlanıyor.

Akıllı sözleşmeler gibi diğer kripto para terimleri de yasa tasarısında açıklanıyor.

Rusya’da Bitcoin’in Kaderini Merkez Bankası Belirleyecek

Dijital Finansal Varlıklara ilişkin yasa tasarının Duma’ya sunulmasından bir gün önce Rusya’da, kripto para birimleri hakkındaki kurumsal tartışmaların önündeki bir engelin daha aşıldığı haberleri çıktı. Maliye Bakanı Yardımcısı Alexei Moiseev de, Rusya Merkez Bankası ve Maliye Bakanlığı arasındaki anlaşmazlıkların çözüldüğü yönündeki bu haberleri doğruladı. Moiseev, Bitcoin gibi kripto paraların ve borsaların kaderine Merkez Bankası’nın karar vereceğini açıkladı.

Geçtiğimiz zamanlarda Merkez Bankası ve Maliye Bakanlığı kripto para sektörünün düzenlenmesi ve ulusal kripto para hakkında bir çok kez karşı karşıya geldiler. Ancak ana uyuşmazlık Rusya’daki kripto para borsalarının yasallaştırılması konusundaydı.

On March 14, the adult industry leader Playboy Enterprises announced the integration of cryptocurrency payments starting with its Playboy TV web portal. According to the announcement, customers will be able to access adult content, exclusives, and augmented reality (AR) and virtual reality (VR) initiatives in the future.

Playboy is an adult lifestyle and entertainment company that was founded in 1953 by Hugh Hefner. The firm became one of the first adult industry leaders within the sex industry and continues to be a dominant player. Headquartered in Beverly Hills, California, Playboy Enterprises publishes magazines, websites, television broadcasts, and radio in roughly 180 countries worldwide. Now the firm plans to introduce cryptocurrency payments for its online services starting with its Playboy TV subsidiary.

Reena Patel, the chief commercial officer and head of operations for Playboy Enterprises, stated:

As the popularity of alternative payment methods continues to grow around the world, along with the reach of Playboy’s digital platforms, we felt it was important to give our 100 million monthly consumers increased payment flexibility.

Rewarded for Engaging with Playboy Offerings
According to Playboy, the company will integrate a multi-cryptocurrency wallet that will hold a variety of top digital assets and a coin called Vice Industry Token (VIT). By using cryptos to pay for exclusive adult content, customers will be able to “earn tokens to view Playboy.TV’s original content, as well as comment on and vote for content.”

“This innovation gives the millions of people who enjoy our content, as well as those in the future who participate in our casual gaming, AR and VR platforms, more choices with regard to payment and in the case of VIT, an opportunity to be rewarded for engaging with Playboy offerings,” explains Patel.

This isn’t Playboy’s first rodeo with cryptocurrencies as the Playboy Brand Website; Playboy Plus started accepting BTC payments back in February of 2014.

What do you think about Playboy TV adding a crypto-wallet? Do you think cryptocurrencies and adult entertainment is a good mix? Let us know your thoughts in the comments below.

6  Bitcoin / Press / [2018-03-14] South Korean Researchers Unveil ‘Leger-Free Blockchain’ Built for C on: March 14, 2018, 11:46:56 PM
A group of South Korean researchers has unveiled a “ledger-free blockchain” called “PureChain” that it says could hasten the introduction of a central bank digital currency (CBDC).

The research team — which includes representatives from the Korea Advanced Institute of Science and Technology, Kyung Hee University, tech firm ICTK Holdings, and blockchain startup EpitomeCL — announced the development of PureChain in a press conference last week.

According to the Korea Times, PureChain is a “ledger-free blockchain” constructed using physical unclonable functions (PUF), the “digital fingerprints” that are used to identify microprocessors and other semiconductor devices.

Researchers said that, by employing PUF, users could make peer-to-peer (P2P) payments “through consensus between two engaged nodes only,” netting dramatic improvements in transaction speed over Bitcoin and other conventional blockchains.

They explained that, previously, PUF technology had required the use of “error correction codes” when used as a key in cryptographic algorithms. However, they said that they had discovered a solution for this problem.

“PureChain is the only PUF technology that does not require the use of error correction codes that have hindered mass production of other types of PUF,” ICTK Holdings CEO S. Sam Yu said. “As a result, the applications of PUF range far and wide from blockchain technology to IoT security, user verification and much, much more.”

The developers predicted this technology could hasten the introduction and adoption of central bank-governed digital currencies, which would allow nations to digitize their national currencies and capitalize on the efficiency of blockchain-related systems without relinquishing control of the money supply.

“It is a realistic blockchain technology that can be applied to CBDC,” said Han Ho-hyeorn, a Kyung Hee University professor and the leader of the PureChain research team.

Unfortunately, many questions remain about PureChain. Regional media outlets who covered the press conference did not go into detail about the structure of the network’s “ledger-free blockchain.” Nor, for that matter, did they explain how the technology avoids the use of PUF error correction codes.

However, if PureChain does prove to be as useful as researchers claim, expect central banks to begin eyeing it as a potential tool to help them transition their countries into cash-free societies.

7  Local / Bitcoin Haberleri / Güney Kore’nin En Büyük Borsası Uluslararası Havaleler için Bitpay ile çalışacak on: March 14, 2018, 11:43:11 PM

Güney Kore’nin en büyük kripto para borsası olan Bithumb, uluslararası havale ödemelerini kolaylaştırmak için meşhur kripto para ödeme işlemcisi BitPay ile işbirliği yaptı.

ABD ve Güney Kore

BitPay’in baş ticari sorumlusu  Sonny Singh, şirketin 2018’de 4 milyar dolar değerinde işlem hacmi yolunda ilerlediğini ve ekibin bitcoin gibi kripto paraların, büyük ölçekli perakendecilere kripto parayı bir ödeme yöntemi olarak entegre edilmesine yardımcı olarak sıradan kullanıcılar için daha ulaşılabilir olmasını sağlamaya odaklandığını belirtti.

CNBC ile yaptığı bir röportajda Singh, şirketin Güney Kore ile batı arasındaki ödemeleri hedefleyerek 200 milyar dolarlık havale sektörü için Bithumb ile ortaklık kurduğunu açıkladı.

Singh şöyle dedi :

“Güney Kore ve batıda ,sınır ötesi ödemeler bu yıl 200 milyar dolarlık bir endüstri haline geldi. Bithumb, bariz şekilde dünyanın en büyük borsalarından biri. ”

2014 yılından bu yana, Bir kaç havale odaklı şirket, Western Union ve Moneygram gibi mevcut havale servis sağlayıcılarını kullanırken, artık hem havale yapan hem de alıcılar tarafından ödenen pahalı ücretler ve masrafları göz önünde bulundurarak, büyük miktardaki havale ödemelerini işlemek için kripto-para birimlerini kullanmaya başladılar.

Geleneksel havale şirketlerinin bir dezavantajı, havale merkezlerinin bulunmadığı şehirlerde veya kırsal alanlarda, alıcıların paralarını almak için uzak mesafelere gitmeleri gerektiği, bunun da  zaman alıcı ve maliyetli hale gelmesidir.

Singh, Bithumb ve BitPay arasındaki ortaklığın, kullanıcıların sınır ötesi ödemelerini yüzde 1’lik bir ücret ve  1 günlük bekleme süresi garantisiyle işleme koymalarını istediğini ifade etti.

Singh şöyle devam etti:

“İnsanların uluslararası olarak tedarikçilerden daha ucuz ve hızlı para alabilmesi için bunu yapmaya çalışıyoruz. Şu anda, Güney Kore’deki bir kişi, Bithumb’u kullanarak bitcoin satın almak ve faturayı ödemek için milyon dolarlık bir fatura ödeyebilir ve BitPay bu faturayı işleyecek ve bir sonraki iş gününde ABD dolarına yerleştirecektir.”

Bithumb ayrıca, Güney Kore ‘de ülkedeki herhangi bir bireyin kripto para ürünlerini kolayca satın alıp satabilmesi için kripto-para birimli ATM’leri kurmaya başladı ve aynı zamanda kripto para birimleriyle havale ödemeleri yapma sürecini kolaylaştırdı.

Asya Pazarı
BitPay ve Bithumb, Güney Kore’den ABD’ye havale piyasasını hedeflemeye odaklanırken, Güney Kore’nin en büyük internet şirketi Kakao gibi diğer şirketler, 500 milyar dolar değerindeki Asya havale piyasasına hizmet vermeye odaklanıyor.

Geçen yıl, her sektörde yüzde 90 pazar payı ile mesajlaşma, fintech, taksi ve sosyal medya sektörleri üzerinde kontrol sahibi olan Kakao,Filipin’in en büyük bitcoin odaklı yatırım ve havale şirketi olan Satoshi Citadel Industries ‘ten yüzde hisseyi satın aldı.

Satoshi Citadel tarafından işletilen bir kripto-para birimi tabanlı havale uygulaması olan, Filipinler ve Asya’daki birçok ülke arasında havale ödemeleri gerçekleştiriyor.

Güney Kore ve ABD gibi çoğu gelişmiş ülkede, expat işçileri havale hizmeti sağlayıcılarına güvenmiyor, bankalar ile ödeme yapmak ve almak için çalışıyor. Ancak, yerel işçiler için nispeten düşük ücret ve bankacılık hizmetlerine erişimin sınırlı olduğu Filipinler ve Malezya gibi ülkelerde, çalışanlar ödemeleri yapmak için havale platformlarından yararlanmaktalar.
8  Bitcoin / Press / [2018-03-13] World’s Central Bank: Crypto Could Risk Bank Runs on: March 13, 2018, 10:14:38 PM
How many central banks are actually considering their own version of cryptocurrency is unclear, Russia and Venezuela being the most infamous examples. To perhaps ward off serious consideration from more established economies, the Bank for International Settlements (BIS), the world’s central bank to central bankers, is suggesting state-backed crypto might destabilize commercial banks’ customer deposits, negatively impacting the “efficiency of financial intermediation.”

Central Banks Warned About State-Backed Crypto

Chairs of two BIS working groups, Klaus Löber (European Central Bank) and Aerdt Houben (Netherlands Bank), submitted Central Bank Digital Currencies, a 34-page document meant to be a “high-level overview of [central bank digital currency (CBDC)] implications for payments, monetary policy and financial stability. The analysis of the committees reflects initial thinking in this rapidly evolving area and is a starting point for further discussion and research. It also highlights that the issuance of a CBDC requires careful consideration,” it outlines in the Foreword.

The word, “careful,” in one form or another, is sprinkled half a dozen times throughout, as in “Any steps towards the possible launch of a CBDC should be subject to careful and thorough consideration. Further research on the possible effects on interest rates, the structure of intermediation, financial stability and financial supervision is warranted. The effects on movements in exchange rates and other asset prices remain largely unknown and also deserve further exploration.”

The BIS has been particularly vocal of late on the subject of crypto, as when last month its General Manager stressed “while perhaps intended as an alternative payment system with no government involvement, it has become a combination of a bubble, a Ponzi scheme and an environmental disaster.” The 87 year old, Basel, Switzerland-based central bank is the world’s lender of last resort to the lenders of last resort.

The report is revealing in the sense it appears cryptocurrency is an increasingly important topic of conversation, and that at least some central banks are considering competing alternatives as perhaps an answer. Where last month’s BIS comments dismissed crypto, the present report doesn’t outright condemn a state-backed coin. The paper “finds that wholesale CBDCs might be useful for payments but more work is needed to assess the full potential. Although a CBDC would not alter the basic mechanics of monetary policy implementation, its transmission could be affected.”

Wholesale Is Preferable for Central Banks

“Many forms of CBDC are possible,” the report emphasizes, “with different implications for payment systems, monetary policy transmission as well as the structure and stability of the financial system. Two main CBDC variants are analysed in this report: a wholesale and a general purpose one. The wholesale variant would limit access to a predefined group of users, while the general purpose one would be widely accessible.”

By contrast, “A general purpose CBDC could have wide-ranging implications for banks and the financial system. Commercial banks’ reliance on customer deposits may become less stable, as deposits could more easily take flight to the central bank in times of stress. Besides consequences for financial stability, effects on the efficiency of financial intermediation need to be carefully considered,” the authors detailed.

World’s Central Bank: Crypto Could Risk Commercial Bank Deposit Runs, Instability
Aerdt Houben
To buttress the wholesale point, the report continues to argue, “Wholesale CBDCs, combined with the use of distributed ledger technology, may enhance settlement efficiency for transactions involving securities and derivatives. Currently proposed implementations for wholesale payments – designed to comply with existing central bank system requirements relating to capacity, efficiency and robustness – look broadly similar to, and not clearly superior to, existing infrastructures. While future proofs of concept may rely on different system designs, more experimentation and experience would be required before central banks can usefully and safely implement new technologies supporting a wholesale CBDC variant.”

Again, this is all very revealing. Too much “general purpose” crypto, even state backed, would destabilize economies, but that doesn’t mean more obviously efficient aspects of the technology shouldn’t be employed as a settlement layer behind the scenes, central bank to central bank. Of course, the BIS loves blockchain technology, and so far the only developed economy seriously flirting with some kind of central bank cryptocurrency is Sweden’s Riksbank (its study for the “e-krona” won’t be ready until next year).

9  Local / Bitcoin Haberleri / PwC ICO Coinlerini Gözetim Altına Alacak on: March 13, 2018, 10:09:26 PM

İngiltere merkezli danışmanlık firması Pricewaterhouse Coopers (PwC) blockchain analiz edebilen bir yazılım geliştirdiği duyurdu. Yazılım sayesinde ICO coin’leri takip edilebilecek. Böylece kullanıcı sahip olduğu kripto paranın herhangi bir yasa dışı işlemde kullanılmadığından emin olabilecek.

PwC ve Hong Kong’lu ortağı Eric Young Asya’da ICO’lara ve kripto paralara artan ilginin projeye ilham verdiğini ifade etti. Yatırımcılar Çin’in kripto paralara karşı yasaklayıcı kanunları dolayısıyla yeni pazar arayışına girmişlerdi. Bu yüzden yatırımcılar kripto paralara daha sıcak bakan ülkelere yöneldiler. PwC Asya’daki Hong Kong’a yönelen kripto para yatırımcıları için sermaye sağlamayı planlıyor. Geliştirilen yazılım hem şirketler için hem de yatırımcılar için daha güvenli bir ortam sağlayacak.

Young ICO sırasında satın alınan kripto paranın piyasaya sürülmeden önce yatırımcı tarafından takip edebileceğini öne sürdü. Bu sayede ICO’yu düzenleyen şirket yatırımcılardan habersiz olarak coin’leri kullanamayacak. Young şöyle konuştu:

‘’Blockchain’de işlem yapıldığı zaman ne kadar kripto para gönderildiğini görebiliyoruz. Ancak sahip olduğumuz ICO coin’leri takip etmemiz mümkün değil. Biz ICO coin’lerinin de takibini sağlayarak daha güvenli bir ortam yaratacağız. Oluşturduğumuz yapay zeka coin’in hangi yasalara tabi olduğunu kullanıcıya bildirecek. Bunun yanı sıra ICO’yu düzenleyen şirketin hangi sektörde çalıştığını bileceğiz.’’

PwC geçtiğimiz aylarda ICO düzenlemeyi planlayan birkaç şirketle beraber çalışmaya başladı ve şirketlere yasalarla ilgili danışmanlık yaptı. Diğer yandan şirketleri kara para aklamaya karşı alınacak önlemler hakkında bilgilendirdi. Geçtiğimiz yıl Kasım ayında PwC’nin Hong Kong danışmanlık ofisi ödemelerde bitcoin kabul edeceğini açıklamıştı.

10  Local / Alternatif Kripto-Paralar / Geleceğin Kripto Parası Ethereum Mu Olacak? on: March 07, 2018, 11:01:19 PM

Geçtiğimiz bir kaç yıl içerisinde en büyük ikinci kripto para birimi olmayı başaran Ethereum, Bitcoin ile kıyasladığımızda daha pozitif yorumlar alan bir kripto para oldu. Ethereum, hem geliştiricilerin çalışmaları hem de yatırımcıların güveni sayesinde dünya çapında popüler bir teknoloji olmayı başardı.

Tek bir makalede Ethereum ve onun teknolojisini anlatmak pek kolay olmayacaktır, ancak dilerseniz sitemizden Altcoin’ler başlığını takip ederek daha detaylı ve teknik bilgilere ulaşabilirsiniz. Haber ve makaleleri inceleyerek de hem konunun uzmanlık alanına girmiş olursunuz hem de Ethereum fork’ları ve bu teknolojinin nasıl atılım yaptığı ve dünya genelinde bu kadar popülerleşmesinin süreçlerine tanık olabilirsiniz.

Ethereum Nedir?

Ethereum’un diğer kripto paralardan ayıran başlıca özelliği, sıradan bir kripto para birimi olmamasıdır. Ethereum, Blockchain teknolojisi ile işleyen ve akıllı sözleşmeler ile Ethereum Sanal Makinesi’ne (EVM) dayanan çok amaçlı bir platformdur. Yani Ethereum, akıllı sözleşmeler yapmak için kullanılabilir.

Blockchain üzerinde saklanan Ethereum akıllı sözleşmeleri, anlaşmaları ve düzenlemeleri basitleştirmek için de kullanılabilir. Bu tür sözleşmelerin asıl avantajı, Blockchain’in merkezsiz olan kontrol ve yürütme sisteminin kullanılmasına izin vermesidir. Bu sistem ise sahtekarlıkları önler ve işlemin değiştirilmesini imkansız hale getirir. Ayrıca Ethereum akıllı sözleşmeleri, geleneksel yolla yapılan sözleşmeler ile karşılaştırıldığında, Ethereum’un, çok daha güvenli olduğu ve düşük işlem ücretleri sağlamak üzere tasarlandığı görülür.

Akıllı sözleşmelerin ekleri, Blockchain teknolojisini kullanarak Ethereum temelinde çalışır. Ayrıca Ethereum, diğer kripto paralar gibi kripto para cüzdanlarında saklanabilir ve bu cüzdanlar akıllı sözleşmeler yaratıp kullanmaya imkan tanır.

Kripto Paranızı Kullanarak Akıllı Sözleşmeler Yaratabilirsiniz

Ethereum kullanıcılarına; dijital hisse senetlerinde ve dijital varlıklarda kullanılabilecekleri token’ler üretme şansı tanır. Bu tip akıllı sözleşmeler; standart kripto API kullanıcısı veya herhangi bir borsa ve kripto para cüzdanı ile uyumludur. Bunun yanında hisse senedi sunma, oy kullanma ve bağış toplama gibi farklı amaçlarla kullanmak için Ethereum web sitesinden kodlar da kopyalanabilir. Bu platformda asıl mümkün olan şey ise, belli sayıda token’i belirli kurallar çerçevesinde serbest bırakmaktır.

Bitcoin ve Ethereum Arasındaki En Büyük İki Fark

*Bitcoin’de ortalama bir blok oluşturma süresi 10 dakika iken, Ethereum bu süreyi 12 saniyeye indirir. Ethereum bu başarıyı GHOST (hayalet) protokolü sayesinde elde eder. Hızlı blok üretmek aynı zamanda işlem hızını da arttırır. Ancak hızlı blok üretmek aynı zamanda blok sayısını da arttırır.

*Bu iki kripto ağı arasındaki bir diğer temel farklılık ise para arzı konusudur. Olası tüm Bitcoin’lerin neredeyse üçte ikisi çoktan kazıldı. Hatta birçoğu 2014 yılından önce kazılmıştı. Ethereum ise ön satışlar sayesinde başlangıç sermayesini topladı ve beşinci yaşına giren bu sistemde toplam Ethereum’ların sadece yarısı kazıldı.

11  Bitcoin / Press / [2018-03-08] SEC Chairman Fires Another Warning Shot at ICOs as Agency Issues ‘D on: March 07, 2018, 10:55:03 PM
The top regulator at the US Securities and Exchange Commission (SEC) has fired yet another warning shot at initial coin offerings (ICOs) that are being used to mask unregistered securities offerings.

In an interview with Fox Business, SEC Chairman Jay Clayton reiterated that a significant portion of the ICOs that he has observed qualify as securities offerings, even though they are marketed as utility token sales and claim that they are exempt from securities regulations.

Clayton said:

“Many ICO’s and many of the ones I’ve looked at specifically are securities. They are offerings of interest in an enterprise where the buyer of the ICO of the token, you can call it a token you can call it a security, is basically saying I’m investing with you with the promise of a future return, whether you deliver something to me in the future as a result of your efforts or because I sell it to somebody else who wants that return in the future. That’s a security, and the SEC’s job is to regulate the offer and sale of securities.”

These are among the SEC chairman’s first public statements on this nascent fundraising model since reports emerged that the agency had issued subpoenas to as many as 80 ICO operators, demanding that they turn over documents related to their token sales.

The SEC is also investigating other offerings — including that of tZero, a subsidiary of e-commerce company Overstock — although these companies have reportedly been asked to hand over documents voluntarily.

In a lengthy exchange, Clayton detailed one of the SEC’s chief problems with the state of the ICO markets, namely that issuers appear determined to “break down [the] traditional approach to public and private markets.” He explained that under SEC guidelines, securities issuers may choose to either conduct their offering as a private placement or as a public offering. Most ICOs, he said, have tried to do both.

“For some reason, people selling ICOs seem to think they don’t need to follow either path they seem to think they can have the best of both worlds. A limited disclosure from a private placement and public trading and public offering of the token. For a long time, since 1933 that’s not been allowed,” Clayton said. “Although I love this new technology the new technology is not a reason to break down our traditional approach to public and private markets.”

Meanwhile, a newly-released letter drafted by an official with the Department of the Treasury suggests that ICOs may also have to register as money transfer businesses, which would subject them to the Bank Secrecy Act and other regulations that, if violated, incur criminal penalties.

Clayton advised investors to “think long and hard” before contributing to ICOs that do not explicitly demonstrate their compliance with SEC regulations, noting that there is little the agency can do to protect investors once the money moves offshore.

But for ICO operators, he had a more explicit admonition:

“Abide by the law,” he warned, “we are watching, others are watching.”

Bitcoin price hit a 10-day low of $9,400 (Bitfinex) as major cryptocurrency exchange Binance froze withdrawals due to “unauthorized market sells.”

Bitcoin shed some of its recent gains today, dropping over 10% on the back of rumors that Binance, one of the world’s largest crypto exchanges by trading volumes, has been hacked.

“WTF is happening! Binance just sold all my alts at market rate and I have got just the Bitcoin now,” a user wrote on Binance’s official Reddit page. “Is it because of account getting hacked or binance bot issue?” Other users expressed similar concerns with their crypto holdings.

Following up with a statement, a moderator for the exchange announced a temporary freeze on withdrawals insisting that the victims, recognized thus far, have registered API keys  – commonly used in trading bots and Binance’s mobile and desktop applications. Binance insists that its platform has not been hacked.

The Binance representative wrote:

We are investigating reports of some users having issues with their funds. Our team is aware and investigating the issue as we speak.

As of this moment, the only confirmed victims have registered API keys (to use with trading bots or otherwise). There is no evidence of the Binance platform being compromised.

13  Bitcoin / Press / [2018-03-08] Binance Users Report Unauthorized Transactions Linked to Viacoin Pu on: March 07, 2018, 10:51:55 PM

Several traders at popular cryptocurrency exchange Binance are reporting that the platform executed unauthorized orders through their accounts, triggering a 400 percent pump for lesser-known altcoin Viacoin.

On Wednesday, Binance users began flooding the exchange’s Reddit page with reports that their accounts had executed unauthorized buy and sell orders.

“WTF is happening!,” one exasperated user wrote. “ Binance just sold all my alts at market rate and I have got just the Bitcoin now. Is it because of account getting hacked or binance bot issue?”

“Everything was cleaned out from my account. Now even Bitcoin is gone. It was used to buy some random Via coin. All value gone,” the user added soon after.

“Same Here! Buy Order executed VIAcoin at horrendous prices,” another user replied.

Indeed, Binance exchange data indicates that a ~325,000 VIA buy order placed shortly before 3 pm UTC increased the price of VIA/BTC by several hundred percent.

A Binance representative quickly responded that the exchange is aware of the issue and is currently investigating it.

“We are investigating reports of some users having issues with their funds. Our team is aware and investigating the issue as we speak. Please remain patient and we will provide an update as quickly as possible,” the employee said.

Most of the affected users said that they had checked their login history for evidence of unauthorized access but said there was no suspicious activity, and several added that they have two-factor authentication (2FA) activated as an extra security measure.

Even so, the incident appeared to affect a limited number of users, and Binance later announced a temporary freeze on withdrawals, claiming that all of the victims it has identified had registered API keys — which are commonly used in trading bots.

The company said that there is “no evidence” that Binance itself had been compromised, and CEO Changpeng Zhoa stated on Twitter that “all funds are safe.”

CZ (not giving crypto away)

All funds are safe. There were irregularities in trading activity, automatic alarms triggered.  Some accounts may have been compromised by phishing from before.  We are still investigating.  All funds are safe.

If the traders’ accounts were compromised through their API keys — which could have been accomplished through a phishing scheme — the hacker would likely have been able to trade on the accounts but not make withdrawals. Consequently, as one trader explained, the hacker likely used Viacoin buy and sell orders to launder the funds to his or her personal account.

However, several affected users protest that they did not use trading bots, and rumors that Binance was hacked continue to circulate through social media channels. These rumors, as CCN reported, have correlated with a significant Bitcoin price downturn.

14  Bitcoin / Press / [2018-03-03] Major Dutch Bank Rabobank Exploring Idea Of Launching Own Cryptocur on: March 04, 2018, 12:07:03 AM

Rabobank, a major Dutch bank with €681 bln under management, roughly equal to $838 bln, is looking into options for developing a cryptocurrency wallet within its online banking environment, according to a press release published Feb. 28.

The idea of a digital wallet for the bank’s own cryptocurrency project “Rabobit” was offered under the bank’s internal “Moonshot” program. The program encourages Rabobank’s employees to propose innovative ideas which can be further developed by the bank.

Although the bank’s official selection of “Moonshot” ideas for actual implementation will be announced in mid-June, Rabobank has already launched a one-page website to promote its potential Blockchain-based service and evaluate the public interest towards it.

According to the one-pager, if released, Rabobit will offer access to all of a customer’s funds “through one bank account”, and allow to “send and receive funds, including cryptocurrencies, in one environment.”

Rabobank, an international financial services provider that has approximately 8.7 million clients around the world, has not always maintained such an open-minded approach to the digital currencies. Last month, an unnamed representative of the bank stated that they considered Bitcoin to be a “risky” product, according to the NL Times news site.

“Ownership and value transfer are completely anonymous and evade supervision by third parties, such as a government. Which means that cryptocurrency does not meet the highest standards of compliance set by Rabobank," the bank’s representative said.

Back in November 2017, another major bank, South Korea’s Shinhan Bank, announced it was in the process of developing its own cryptocurrency wallet. However, disagreements among South Korean authorities about the correct approach to cryptocurrency regulation has put Shinhan’s plans on hold.

15  Bitcoin / Press / [2018-03-03] How Cryptocurrency and Blockchain are Changing Philanthropy on: March 04, 2018, 12:05:45 AM
Much of the growing interest in Bitcoin and other digital currencies has focused on getting and not giving. But flying under the radar is an exciting new trend toward leveraging cryptocurrencies for philanthropy.

Fundraising with Crypto

Over the last few years, a number of charities and foundations have been trialing Bitcoin donations. These include such well-known organizations as the Red Cross, Save the Children, United Way and the Electronic Frontier Foundation. Cryptocurrency donations to charity are clearly on the rise. Fidelity Charitable, which houses the nation’s largest donor-advised fund, received $69 mln in cryptocurrency donations in 2017, up from $7 mln received in 2015 and 2016 combined.

Beyond charity donations are many innovative platforms and projects happening in the emerging “crypto-philanthropy” space. These include crowdfunding platforms such as BitHope, which allows donors to make Bitcoin donations to selected charities for their fundraising campaigns. Besides, some new tools like GiveTrack and Alice can track the flow of donations from donor to a done openly, and to verify what charities have received and achieved, all on a Blockchain.

Charity coins

Beyond cryptocurrency donations and tracking, a number of social purposes digital coins have been created to support specific nonprofit programs and endeavors. Clean Water Coin, for example, was designed to raise money for the nonprofit charity and bring clean water to the families around the world. Pinkcoin, a philanthropy coin which allows investors to both donate to charity and to earn a return on their investment, is listed on major cryptocurrency exchanges and has performed well in comparison to other commercially traded digital currencies.  


Another new arrival in the cryptocurrency for charity space is the “crypto-foundation.” One anonymous investor established a foundation to give away 5,057 Bitcoins.  The motto of the donor’s charity, the Pineapple Fund, is: “Because once you have enough money, money doesn’t matter.” So far, through the anonymous outreach of an individual who goes by the moniker of “pine,” $56 mln has been donated to 56 hand-selected charities.

Further down the road, we may even see an autonomous and decentralized foundation or fund, under which grant and financial distributions are made purely through the votes of holders of foundation created tokens. Such a “Distributed Autonomous Foundation” would be governed by an external collective of shareholders with the right to direct donation flows and even produce and fund project ideas through majority token rule.

Blockchain-based systems could also help to improve the reputation of charities. According to recent studies, one in three Americans are said to lack faith in nonprofits, many believing that these institutions spend too much of their budgets on overhead and too little directly on programs. Reduced overhead spending due to improved operational efficiencies and disintermediation through Blockchain technologies (e.g., direct donor to beneficiary giving) could help restore faith in charitable giving among skeptical givers. This, in turn, could lead to increased philanthropic engagement and a rise in overall giving.

In the future more charities, and even foundations could produce their own cryptocurrencies, the sale of which may enable a new sustainability model. A charity token exchange developed exclusively for the buying and selling of them, may one day bolster a new market-based approach to philanthropy in which both philanthropists and charities make money from trading “digital currencies for good.” Nonprofits and foundations could also engage in fundraising through token mining.

Despite unlimited opportunities, there are many challenges ahead. Most prominent among them is the fact that digital currency donations and Blockchain anchored systems are still new and untested in the world of philanthropy, and there are limited awareness and interest among individual givers, charities, and foundations.

What the future holds

In the short term, it is unlikely that cryptocurrency and Blockchain platforms will significantly disrupt or displace traditional philanthropy, but they will drive further innovation and experimentation in the sector.

As donations through Bitcoin and other digital currencies become more commonplace and acceptable and assuming the crypto market continues to flourish, crypto-philanthropy will indeed grow. There will also be more testing of smart contracts and Blockchain managed to give and to track which, if successful, could establish a new norm for transparency in philanthropy. Ultimately, as givers and beneficiaries interact more directly, we may see diminished roles for charities, aid agencies, and foundations - in some cases even the removal of these entities from the philanthropic equation.

On the flip side, if greater transparency in giving and impact does lead to increased confidence in charities, millions (or even billions) of dollars more could be generated for the social sector.

Regardless of which way the wind blows, it’s a brave new world just waiting to be explored by those wanting to give a little back.

16  Local / Bitcoin Haberleri / AB, Kripto Paralar İçin Acilen Küresel Düzenlemeler Yapılmasını İstiyor on: March 03, 2018, 11:51:35 PM
Avrupa Birliği mali komisyon üyesi Valdis Dombrovskis, kripto para birimlerinin daha geniş bir şekilde düzenlenmesi için çağrıda bulundu ve merkezsiz para birimi olgusunun nasıl ele alınacağı konusunda hala küresel bir fikir birliğine varılamamış olmasının AB’yi tehdit ettiğini söyledi.

Dombrovskis, Kripto Paraların Acilen Düzenlenmesi Gerektiğini Belirtiyor

Dombrovskis, bu hafta Brüksel’de gerçekleşen kripto paralarla ilgili yuvarlak masa toplantısında, konuyla ilgili görüşlerini belirtti ve bazı uyarılarda bulundu.

Avrupa Komisyonu Başkan Yardımcısı Valdis Dombrovskis,
“Bitcoin küresel bir fenomen ve küresel düzeyde, uluslararası bir araştırma yapılması önemli. Ortaya çıkan risklere rağmen düzenlemeler konusunda acilen adım atılmazsa, konuyla ilgili AB düzeyinde ilerlemeler gerçekleştirebiliriz.”
yorumunu yaptı.

Bunun yanında “Kripto Paralar – Fırsatlar ve Riskler” konusunun ele alındığı toplantıda katılımcılar da, AB kurumlarının, üye devletlerin ve denetçilerin, hızlı teknolojik gelişmelerin neden olduğu zorluklara nasıl tepki vereceği hakkında yorumlarda bulundular ve kripto paraların sunacağı fırsatlar konusunda görüşlerini bildirdiler.

Ayrıca Komisyon, Brüksel’de gerçekleştirdikleri bu toplantıda elde ettikleri görüşleri, G20 Zirvesi’nde daha geniş politikalar belirlenebilmesi için kullanmayı da planlıyor.

 Komisyona göre görüşmeler üç ana tema etrafında yapıldı. Bu temalardan İlki, kripto paralar ve finansal piyasalara etkileri, ikincisi, ortaya bir varlık sınıfı olarak çıkan kripto para birimlerine ilişkin yatırımcıların korunması ve piyasa bütünlüğünün sağlanması, üçüncü tema ise, ICO’lara ilişkin kabuller ve zorluklar olarak belirtildi.

Açık, Devamlı ve Tüm Yargı Yetkilerinin İçinde

Dombrovskis, tüm dünyanın ortak bir düzenlemede buluşması gerektiğini,
“Kripto varlık piyasalarında, yatırımcıların, tüketicilerin ve aracıların aralarında bulunduğu, dünya çapında işlemler var. Avrupa tek başına, kripto para ticareti işlemlerinin yalnızca küçük bir kısmını temsil ediyor. Bu yüzden G20 Zirvesi’nde standart düzenlemeler belirlemek için uluslararası ortaklarımızla beraber çalışmalıyız.”
sözleriyle açıkladı.

Bunun ardından başkan yardımcısı, Blockchain teknolojisini takdir ettiğini belirtti. Ancak bu teknolojiyle ilgili henüz dile getirilmemiş birkaç sorun olduğunu da söyledi. Dombrovskis,
“Geleneksel anlamda para birimi tanımına uymayan kripto paralar önemli spekülasyonlara maruz kalmıştır. Bu spekülasyonlar, tüketicileri ve yatırımcıları önemli risklere maruz bırakır. Bu nedenle tüketicilere ve yatırımcılara yönelik yaptığımız uyarıları sıklıkla, açıkça ve tüm yargı alanlarında dile getirmeliyiz.”
yorumunda bulundu.

Ayrıca Dombrovskis konuşmasında ICO’lara da yer verdi. Başkan yardımcısı, ICO’ları büyük bir fırsat olarak gördüğünü ancak ICO sahiplerinin kimliklerinin açık olması gerektiğini ve şeffaflığın olmadığı durumların riske yol açtığını da ekledi.

Komisyonun özellikle kara para aklama ve yasadışı faaliyetlerde kripto paraların kullanılabilir olmasından endişe duyduğunu da belirten Dombrovskis,
“Komisyonumuz bu yüzden dijital para ticaretinin ve cüzdan sağlayıcılarının, Kara Para Aklamayı Önleme Direktifleri’ne uymaları gerektiğini düşünüyor. Bununla birlikte G20 Zirvesi’nde, riskleri ve fırsatları değerlendirerek kripto paralar, ICO’lar ve Blockchain hakkında harekete geçmeye hazırız.”
sözleriyle konuşmasını bitirdi.
17  Other / Meta / google recaptcha on bitcointalk on: February 19, 2018, 06:18:05 PM
Lets remind ourselves of the reasons that google "recaptcha" needs to be removed from this forum completely: 

1)  This eliminates any connection to the forums from China, the most populous country in the world, a country with more English speakers than the United States, as Chinese officials have declared google's predatory strategies a danger to the internet user and blocked all google urls by ip.  Bitcointalk is currently not accessible from mainland china without a VPN or proxy. 

2)  This service is the slowest and most commonly complained about captcha service available, requiring repeated waiting and clicking in medium in which services have been shown to consistently drop users who are required to wait and click.   

3)   Giving some people linked to communications monitoring and surveillance agencies the login metadata of all users of a financial forum like this is not a good idea.

4)  It doesn't work anyway.  At best captcha services provide whack-a-mole level security.  If throwing a speed bump up for would-be script kiddies to attack the site is the idea, then why not use one of the many other captcha services which don't offer problems 1 - 3. 

Thanks for your consideration, lets keep this forum alive please.     
18  Economy / Economics / What if there never was QE? on: February 02, 2015, 06:19:51 PM
What if we've been fooled with all this talk of expanding fiat supplies?  After all, I never got any of the checks.  Nobody I knew did.  All I know is what I hear some spokesman say, and that makes me think probably it is false based on past experience.  

So, how would we know if actually there's been an attempted tightening of supply over the last 6 years?  Maybe lower oil prices?  Lower gold?  Stronger dollar?  

It might be impossible to tighten supply, but somehow it has happened before.  Equities say otherwise I guess. What do you think?  
19  Other / Politics & Society / File sharing promotion by "high court" on: December 06, 2014, 11:49:45 AM
I know very little about the sillyness of their name or the legitimacy of their operations.
However, somebody over there has earned my respect with their promotion of file sharing websites:

It is of course our civic duty to help one another and thus help ourselves.. sharing of information and culture helps everyone.  So a special thanks to whomever it was over there at the "high court" for publishing this list! 

20  Bitcoin / Bitcoin Discussion / a funny thing happened to namecoin last night on: August 22, 2014, 05:44:28 AM

After a number of very large aggregating TXs started to circulate mempools filled up and it looks like around block 192328 miners started to asphyxiate.  Hash rate went way down (factor of 5-10 ?) and no TXs went through for several hours.  I found only one short thread about this in a namecoin forum and even that was edited later downplaying the event. 

Would these kind of TXs on the bitcoin classic network also cause problems?
