EOS is yet another Ethereum competitor that uses a “Delegated Proof of Stake” (DPOS) system, which supposedly improves on the regular PoS system because users can delegate their voting rights to others in the network in order to decrease transaction verification times and make the network run more efficiently.

נכון. כמו ביטקוין, גם מטבעות אלטרנטייבים מאכסנים בארנק דיגיטלי. אך מכיוון שלא מדובר באותו הבלוקצ’יין, יש לאכסן מטבעות אך ורק בארנק תואם. אם תשלחו ביטקוין לארנק של ביטקוין קאש למשל, סיכוי גבוה מאוד שהביטקוין יאבד לכן חובה לאכסן את המטבע אך ורק בארנק הייעודי שלו. בדרך כלל בדף הבית של אתר המטבע נמצאים גם הארנקים היעודיים. ארנק מומלץ לאתריום ולטוקנים ERC-20 על רשת אתריום הוא MyEtherWallet.

ביטקוין מאחסן את כל ההיסטוריה של עסקאות שהתרחשו אי פעם, הנקראות שרשרת רצופה של בלוקים או בלוקציין. שרשרת הבלוקים יודעת הכול. לכן, אם יש לך כתובת ביטקוין בשימוש ציבורי, אז כל אחד יכול לראות כמה ביטקוינים יש לך על החשבון. מצד שני אם אתה לא אומר שזו הכתובת שלך, אז אף אחד לא יידע אי פעם שזה שייך לך. עבור אנונימיות מלאה, כתובת אחת של ביטקוין משמש בדרך כלל עבור עסקה אחת.

Conclusively, cryptocurrencies like Bitcoin and Ethereum have significant advantages over banks in a of areas, including security, borderless transaction settlement, efficient payment clearance, and lack of dependence on centralized service providers or entities.  Although the offshore banking industry is valued at $32 tln and the valuation of the cryptocurrency market remains below half a trillion, the above-mentioned advantages could allow cryptocurrencies to compete against banks across many sectors.

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.

Ever since Bitcoin first appeared on the scene several years ago, fans of the cryptocurrency have been searching for a way to apply the idea that might capture the public imagination and broaden the use of the technology beyond just geeks and programmers.

שר הכלכלה אלי כהן: “החלטנו להקצות בערבות מדינה מיליארד שקל אשראי לענף היהלומים. שמשרד הכלכלה יעניק 12 מיליון שקלים למרכז החדשנות הטכנולוגי שקם בבורסה ו-10 מיליון שקלים למימון תערוכות וכנסים שמסייעים לייצוא היהלומים. עמיד קרן לטובת מכון היהלומים שתעניק הלוואות נוספות ב-20 מיליון שקלים ונסייע במימון הקמת מפעל חדש לליטוש אבנים גדולות ויהיו גם הקלות רגולטוריות”.

בסופו של דבר, כל מחשב יכול “לכרות” מטבעות חדשים. עם זאת, מכיוון שמדובר בפעולה שיכולה לארוך זמן רב עם כוח החישוב של מחשב אישי, ניתן להצטרף לקבוצת כרייה שמאגדת כוח מחשוב של מספר משתמשים ומחלקת ביניהם את התוצר.

Since falling from the January peak of 33,484.1 Hong Kong’s Hang Seng Index has found support twice around the long-term uptrend line and it continues to hold. Last weeks low of 29,852.40 was the second time that the index bounced off the support area around the line. This tells us to keep an eye on the line going forward for signs of a change in the relationship between the price and the line. In addition, notice that the brown 100-day moving average (MA) support line on the enclosed chart has been parallel to the trend line for a year. The 100-day MA is currently at 30,081.39.

There are zero transaction fees on transfers when you send or receive POW ‘lite’ between other POWtoken.com account holders. At some point in the future we may introduce a small fee to cover the running costs for the centralised servers. If POWtoken.com proves to be a massive success, the costs of a centralised server could be start to be quite large and will require a small fee to be added to each transaction. This fees would likely be just 1 or 2 cents per transaction which is still a fraction of the costs of making similar transactions on the Blockchain currently.

In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt.[25] This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009.[25] However, with more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them.[25][26]

Initial Coin Offerings.  Coinciding with the substantial growth in cryptocurrencies, companies and individuals increasingly have been using initial coin offerings to raise capital for their businesses and projects.  Typically these offerings involve the opportunity for individual investors to exchange currency such as U.S. dollars or cryptocurrencies in return for a digital asset labeled as a coin or token.

One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party – a central server – that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand.
