“Cryptocurrencies שקופית מטבע דיגיטלי טכנולוגיה”

As the price of Bitcoin climbed, investors got interested in other cryptocurrencies. With no explanation, the price of Dogecoin doubled, then tripled. Two months after it was introduced, Mr. Palmer’s joke was worth $50 million, and some early Dogecoin adopters, who called themselves “shibes,” were sitting on lucrative stockpiles.

As for crypto currencies, there are basically two ways to use them. You can use them as an investment, hoping they’ll appreciate in value. Bitcoin is good for this (unless it crashes), since the supply is finite. The other way is to use them purely for transactions, for which Ethereum is better. In the second case, as long as you don’t hold the crypto currency for long term, there’s little risk.

Dash uses a two-tier architecture for its network. The first tier consists of miners who secure the network and write transactions to the blockchain, and the second tier is made of “masternodes.” Masternodes relay Dash transactions and enable the InstantSend and PrivateSend types of transactions.

Last year, Saudi Arabian billionaire Prince al-Waleed Bin Talal was arrested by the government of Mohammed Bin Salman, who is expected to take control over Saudi Arabia and become its ruler, as the most powerful figure in the Middle East. The government of Salman initiated an anti-corruption purge, arresting 11 Saudi princes and 200 businessmen.

Around the same time, Nick Szabo, a computer scientist who now blogs about law and the history of money, was one of the first to imagine a new digital currency from the ground up. Although many consider his scheme, which he calls “bit gold,” to be a precursor to Bitcoin

Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC’s complaint stated that Garza, through his companies, had fraudulently sold “investment contracts representing shares in the profits they claimed would be generated” from mining.[58]

Civil, founded by Matthew Iles last year, is building what it hopes will be an open marketplace for journalists, scheduled to launch in the spring of 2018. The building blocks of the project are blockchains and a bespoke cryptocurrency, a system of “tokens” that will both fund the development of the platform and compensate writers and editors.

Nvidia is reportedly asking retailers to do what they can when it comes to selling GPUs to gamers instead of miners. “Gamers come first for Nvidia,” said Boris Böhles, PR manager for Nvidia in the German region, in an interview with the German publication ComputerBase. “All activities around our GeForce products are for our core audience. We recommend our trading partners make arrangements to ensure that gamers’ needs are still met in the current climate.”[91]

On top of that, Cardano’s developers have formally verified some core components of the network, including its Proof of Stake (PoS) system, which should also drastically increase its security. The “Ouroboros” algorithm for PoS systems was also peer-reviewed by multiple cryptographers.

Ethereum has recently faced some scaling issues as the number of companies launching an “Initial Coin Offering” (ICO) has boomed. The network has been bogged down for many hours or even days at a time due to a handful of popular projects launching their own ICO to raise funds.

The cash itself wasn’t a crime; Gurlitt had reportedly visited Switzerland to sell a picture to a gallery in Bern. But the strangeness of the situation led to further investigation of Gurlitt’s finances, and a search warrant for his Munich apartment that in February 2012 uncovered one of the most extraordinary stashes of art since the end of World War II. Inside a small flat in a boxy white building, hidden in filing cabinets and suitcases, investigators found more than 1,500 works by artists including Picasso, Matisse, Monet, Liebermann, Chagall, Durer, and Delacroix. The German authorities were investigating Gurlitt for tax evasion; what they found instead was an amassment of art that was immediately, incontrovertibly suspicious.

In 2015, he announced he was leaving Dogecoin behind, telling an interviewer that the cryptocurrency market “increasingly feels like a bunch of white libertarian bros sitting around hoping to get rich and coming up with half-baked, buzzword-filled business ideas.”

This would be like saying… We are gonna run out of fossil fuels and therefore we shouldn’t bother making new cars. Crypto currency is here to stay. Why..? Because there’s a big paradigm shift that people are beginning to realize how much they are being robbed by the banksters and their FIAT currency.

A global ‘Airdrop’ of POW ‘lite’ with enough to be claimed by every person on the planet, can be easily claimed by logging in with your Facebook or Twitter account (if you have both you can make two claims!). POW has the potential to be the most widely held currency on the planet.

ביטקוין קאש – זה פורק “מקבילה” של ביטקוין. כיוון שקוד של מטבעות של כסף וירטואלי פתוח, כל אחד יכול ליצור מטבע חודש תוך שימוש בקוד של מטבע קיים במידה ותתן למטבע הזה שם אחר. יש דעה בבראנגה שביטקוין קאש בשונה מביטקוין – זה מטבע לעניים. זה חיקוי של זהב

כידוע, לרוב רובם של המטבעות הדיגיטליים וגם בביטקוין ובאית’ריום העומדים בראש הטבלה, יש בלוקצ’יין שקוף.  כזה המאפשר מעקב פומבי אחר כל העסקאות ברשת. אז נכון שלא ניתן לדעת למי שייכת כתובת ביטקוין ספציפית רק מלהסתכל עליה אבל במידה ואכן מתגלה קשר בין זהותו של אדם בעולם האמיתי לכתובת ספציפית ברשת, באותו רגע פרטיותו הפיננסית נפרצת והופכת חשופה לעיני כל. כמו גם כל תנועה שעשה בעבר או יעשה בעתיד. (לפחות באופן חלקי שכן אדם אחד יכול וסביר שגם מחזיק ביותר מכתובת ביטקוין אחת).

Cryptocurrency networks display a marked lack of regulation that attracts many users who seek decentralized exchange and use of currency; however the very same lack of regulations has been critiqued as potentially enabling criminals who seek to evade taxes and launder money.

If you are considering investing in cryptocurrencies, it may be best to treat your “investment” in the same way you would treat any other highly speculative venture. In other words, recognize that you run the risk of losing most of your investment, if not all of it. As stated earlier, a cryptocurrency has no intrinsic value apart from what a buyer is willing to pay for it at a point in time. This makes it very susceptible to huge price swings, which in turn increases the risk of loss for an investor. Bitcoin, for example, plunged from $260 to about $130 within a six-hour period on April 11, 2013. If you cannot stomach that kind of volatility, look elsewhere for investments that are better suited to you. While opinion continues to be deeply divided about the merits of Bitcoin as an investment – supporters point to its limited supply and growing usage as value drivers, while detractors see it as just another speculative bubble – this is one debate that a conservative investor would do well to avoid.

סטלר הוא פרוטוקול קוד פתוח, המבוסס על טכנולוגיית הרישום המבוזר (DLT). כל העסקאות ברשת מאוחסנות על יומן מבוזר (ledger) אשר נשמר במלואו על כל שרת, ובכל 2-5 שניות, מתבצע סנכרון של היומנים בין השרתים ברשת. כל פרט או ארגון יכול לשמש כשרת, וככל שמספר השרתים גדל כך הפונקציונליות של הרשת גדלה.

כעת כל שנותר הוא לאשר את ביצוע העסקה. שימו לב, מדובר בשוק של קונים ומוכרים, במידה והפקודה שהעברתם תהיה מתחת למחיר המכירה הכי נמוך, היא תתווסף ללוח הפקודות ותתבצע כאשר המוכרים ימכרו לתוכה. קיים סיכון שהפקודה לא תתבצע כלל והשוק יברח לנו, מנגד, אם כן תתבצע הפקודה נקבל מחיר יותר נמוך ונשלם עמלת פעולה מופחתת (0.15% לעומת 0.25%).

Given the economic and environmental concerns associated with mining, various “minerless” cryptocurrencies are undergoing active development.[28][29][30] Unlike conventional blockchains, some directed acyclic graph cryptocurrencies utilise a pay-it-forward system, whereby each account performs minimally heavy computations on two previous transactions to verify. Others utilise a block-lattice structure whereby each individual account has its own blockchain. With each account controlling its own transactions, no traditional proof-of-work mining is required, allowing for free, instantaneous transactions.[31]

Cryptocurrency is also used in controversial settings in the form of online black markets, such as Silk Road. The original Silk Road was shut down in October 2013 and there have been two more versions in use since then; the current version being Silk Road 3.0. The successful format of Silk Road has been widely used in online dark markets, which has led to a subsequent decentralization of the online dark market. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[52]

A fork happens when a group of developers decide they don’t like the direction of the current software roadmap and then take the existing code and add their own improvements to it. This creates a separate version of the previous software with its own roadmap.

הערך שהמטבע מציע – הערך שמציע המטבע של סטלר, ה-XLM, ביחס לערך שמציעה הפלטפורמה, הוא מינורי. לפי אתר החברה, השימוש העיקרי במטבע הוא לשם מניעת התקפות הצפה (גביית עמלות המשולמות באמצעותו) ולנזילות בין מטבעות עם נפח מסחר נמוך. כלומר, ע”מ לבצע מסחר והמרות של מטבעות, ברב המכריע של המקרים, אין צורך ב-XLM (פרט לעמלות המינוריות, שממילא מוחזרות למשקיעים).

David Mazières is best known for co-authoring “Get Me Off Your F—–g Mailing List,” a novelty paper that in 2014 was accidentally accepted for publication by the International Journal of Advanced Computer Technology (IJACT). He currently serves as the Chief Scientist of Stellar Development Foundation, where he conducted the work presented in this talk. Everyone trying to communicate with Mazières hates Mail Avenger, his open-source anti-spam SMTP server, though his mail synchronization tool “muchsync” has garnered a less hostile reception. Despite not having a normal email address, Prof. Mazières manages to hold down additional jobs as a Professor of Computer Science at Stanford and a co-founder of Intrinsic (formerly GitStar).
