Ethereum Classic is the original version of Ethereum; the new “Ethereum” is a fork of this original version. The split happened when a decentralized autonomous organization built on top of the original Ethereum was hacked. “The DAO,” as this organization was called, acted as a venture capital fund for future distributed applications that would be built on top of Ethereum.
Unlike IPOs, however, ICOs are catnip for scammers. They are not formally regulated by any financial authority, and exist in an ecosystem with few checks and balances. OneCoin loudly trumpeted its use of blockchain technology, but holes in that claim were visible long before international law enforcement took notice. Whereas Gnosis had experienced engineers, endorsements from known experts, and an operational version of their software, OneCoin was led and promoted by known fraudsters waving fake credentials. According to a respected blockchain engineer who was offered a position as OneCoin’s Chief Technology Officer, OneCoin’s “blockchain” consisted of little more than a glorified Excel spreadsheet and a fugazi portal that displayed demonstrably fake transactions.

“With open governance and crypto-economics, we can create a sustainable place for journalism —even the kind of local, policy, and investigative journalism that has been most eroded,” the company said in a white paper published online in October. “Decentralization is the key to a free and independent press.”
On December 6, 2017, more than $60 million worth of bitcoin was stolen after a cyber attack hit the cryptocurrency mining platform NiceHash (Slovenia-based company). According to the CEO Marko Kobal and co-founder Sasa Coh, bitcoin worth $64 million USD was stolen, although users have pointed to a bitcoin wallet which holds 4,736.42 bitcoins, equivalent to $67 million.

While the whole world has adopted the ‘Sharing Economy’ in areas like driving and accomodation, IOTA enables a whole new realm where anything with a chip in it can be leased in real time. Most of our belongings stay idle for the vast majority of time that we possess ownership of it, but through IOTA a lot of these things like Appliances, Tools, Drones, eBikes etc. and resources such as computer storage, computational power, WiFi bandwidth etc. can be turned into leasing-services effortlessly.
Most cryptocurrencies are designed to gradually decrease production of currency, placing an ultimate cap on the total amount of currency that will ever be in circulation, mimicking precious metals. Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement. This difficulty is derived from leveraging cryptographic technologies.
Some miners pool resources, sharing their processing power over a network to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A “share” is awarded to members of the mining pool who present a valid partial proof-of-work.
DasCoin’s proof-of-value distribution protocol prevents wealth concentration within the currency and assures a much wider and more equitable distribution of coins, enhances the stability of the system.
POW ERC20 is an Ethereum Blockchain asset or ‘token’. Ethereum is the second largest cryptocurrency on the planet. Ethereum is slightly different to Bitcoin in that it is designed to allow 3rd parties (such as POW) to create ‘Tokens’ which piggyback on the Ethereum Blockchain. It means that you get all the benefit of a Blockchain, without the need for creating a network of miners to keep the ledger up-to-date. Of course, the miners have to be paid, which is why transaction costs on the Ethereum network are actually quite high. Our innovation is to ‘lump’ all the users accounts together (rather like a nominee service does for equity holdings) and keep them on a single ETH address (ETH or Ether, is the currency of the Ethereum Blockchain). We then get really creative by issueing the users with POW’lite’ which they can trade with other POWtoken.com account holders, with zero transaction fees. The POW’lite’ collectively add up to the total number of POW ERC20 being held in the single ETH account designated for this purpose. As we talk about elswhere in these FAQs, the plan is to create a bridge between the POW’lite’ world and the POW ERC20 world, by Feb 2018.
Some of the limitations that cryptocurrencies presently face – such as the fact that one’s digital fortune can be erased by a computer crash, or that a virtual vault may be ransacked by a hacker – may be overcome in time through technological advances. What will be harder to surmount is the basic paradox that bedevils cryptocurrencies – the more popular they become, the more regulation and government scrutiny they are likely to attract, which erodes the fundamental premise for their existence.
בינואר 2009 פרץ הביטקוין לחיינו, ונדמה שכולם יודעים עליו הכל ■ המרדף אחרי אותו “יפני” מסתורי שהמציא אותו מסעיר את הדמיון ■ אז מי לעזאזל יכול להמציא דבר כזה – והאם ייתכן שכל זה בכלל הוא חלק מהפתעה גדולה שמכינה ארה”ב לעולם?
But as cryptocurrency becomes more mainstream, ICOs will present greater risks to larger numbers of people. There are few barriers to participation aside from knowing how to conduct a Bitcoin transaction, and the space mostly lacks the robust independent analysis performed by underwriters in the IPO market, which can help tamp down overoptimism. The risk isn’t just to individual investors; many argue that the mania of the late-1990s internet bubble ultimately slowed the entire sector down by making investors skittish for years afterwards. Imagine how much worse things might have been if the whole thing had been entirely unregulated.
Cryptography was born out of the need for secure communication in the Second World War. It has evolved in the digital era with elements of mathematical theory and computer science to become a way to secure communications, information and money online.
Central to the genius of Bitcoin is the block chain it uses to store an online ledger of all the transactions that have ever been conducted using bitcoins, providing a data structure for this ledger that is exposed to a limited threat from hackers and can be copied across all computers running Bitcoin software. Many experts see this block chain as having important uses in technologies, such as online voting and crowdfunding, and major financial institutions such as JP Morgan Chase see potential in cryptocurrencies to lower transaction costs by making payment processing more efficient.
