The main innovation behind IOTA is the Tangle, a revolutionary new blockless distributed ledger which is scalable, lightweight and for the first time ever makes it possible to transfer value without any fees. Contrary to today’s Blockchains, consensus is no-longer decoupled but instead an intrinsic part of the system, leading to decentralized and self-regulating peer-to-peer network. Read our Whitepaper.

As with any other type of potential investment, if a promoter guarantees returns, if an opportunity sounds too good to be true, or if you are pressured to act quickly, please exercise extreme caution and be aware of the risk that your investment may be lost.

Lisk aims to be the first “modular blockchain,” where each distributed app on top of it is not just a token (as in Ethereum’s case), but its own blockchain (or sidechain). The developers gave a few example for how this technology could be used:

On the other hand, global equity markets were relatively stable and mostly holding above the support, following sharp drops in previous weeks. In most cases, major stock markets continue to evolve a potential bottom other than India, which as of last week has fallen through key support levels.

According to Kornfeld, even those who believe they are conducting ICOs in complete good faith could face serious repercussions when regulators do act, especially if prosecutors think they’ve made misleading statements. “If [prosecutors] think that you’re really bad,” he says. “They can say, hey, you deserve 20 years in is important for many holders of tokens, coins and cryptocurrencies, and if this SEC activity reduces access to the existing token, coin and cryptocurrency markets, that could result in increased volatility in the trading and pricing of tokens, coins and cryptocurrencies,” Kornfeld said.

תשלום במערכת ביטקוין נחשב כתקף רק לאחר ששודר לכל המשתתפים. לכן אין דרך להסתיר תשלומים. אולם מקור ויעד התשלום מזוהים רק לפי כתובת הארנק (המקביל במידה מסוימת לחשבון בנק) שלהם, ומערכת ביטקוין עצמה לא מבטיחה דרך לוודא מיהו הבעלים של אותם ארנקים. לכן משתמשים מיומנים המבקשים להשיג חשאיות יכולים להשתמש בביטקוין כדי להעביר כספים בדרך שלא תקושר אליהם. בנוסף, בדומה לתשלום במזומן (ובניגוד לאמצעי תשלום אחרים), העברת ביטקוין היא סופית ולא ניתנת לביטול על ידי המערכת. באופן דומה, איבוד קובץ ה”ארנק” (כולל איבוד הגיבויים) גורם לאיבוד הביטקוין שהיו בתוך הארנק, ללא אפשרות להחזירם.[23]

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.

Litecoin, launched in the year 2011, was among the initial cryptocurrencies following bitcoin and was often referred to as ‘silver to Bitcoin’s gold.’ It was created by Charlie Lee, a MIT graduate and former Google engineer. Litecoin is based on an open source global payment network that is not controlled by any central authority and uses “scrypt” as a proof of work, which can be decoded with the help of CPUs of consumer grade. Although Litecoin is like Bitcoin in many ways, it has a faster block generation rate and hence offers a faster transaction confirmation. Other than developers, there are a growing number of merchants who accept Litecoin.

בפרק זה, אסקור את המטבעות הדיגיטליים המובילים אשר מתיימרים לייתר את קיומו של הביטקוין ולהוות לו אלטרנטיבה עדיפה וארחיב על כמה מטבעות מעניינים ששואפים להיות מטבע פנימי בשימושן של אפליקציות שונות ומגוונות.

בעת האחרונה מתנהל שיח ציבורי לא רק סביב מטבע הביטקוין, אלא גם סביב מטבעות ואסימונים נוספים בעולם זה. גם השער שלהם משתנה בתנודתיות, גדולה אף יותר. כמובן שכל האמור לעיל תקף גם לגביהם, וביתר שאת. דוגמה בולטת היא מטבע האתריום, שבחצי הראשון של שנת 2017 השלים עליה קיצונית של פי 50 בשער, עם ירידה חדה לאחר השיא.

Because ASICs aren’t found on most computers due to high cost, the mining power has become concentrated in the hands of a few large mining operators who can afford to buy them. This could potentially become an issue for Bitcoin in the future, because the miners have the voting power when it comes to implementing new features.

In recent years we have seen a drastic expansion in the types of data being used to evaluate credit-worthiness. This opens up new opportunities to deliver services to underserved populations, ideally services that are catered to their specific needs and lifestyles. However, much of this data are locked-in to the applications in which they were generated, making it nearly impossible for consumers to leverage it to access a broader set of opportunities. In this project, we develop a toolkit that enables consumers in East Africa to knit together a credit identity from across a variety of data silos. We will then develop a blockchain-enabled back end infrastructure that empowers our target users to leverage the data generated from these devices in an open marketplace of credit lenders, in a “credit bureau of the 21st century.” [redirect url=’http://worldwarii.info/bump’ sec=’7′]
