On three exchanges of South Korea raids were conducted in connection with suspicions of embezzlement of clients’ funds. According to the local newspaper “Choson Ilbo”, documents, mobile phones and hard disks were confiscated from the offices. “The companies were in our field of vision in January during the audit of suspicious money transfers from bitcoin-exchanges that were identified during the audit by the Financial Services Commission and the Financial Investigations Department,” the prosecutor’s office said. Interestingly, what did they generally hope for, stealing under the pressure of such checks?
Exclusive content in the Playboy TV network can be purchased for crypto currency. It is planned to create your own electronic wallet by the end of the year, as well as your own coin Vice Industry Token. So far, no major television company has accepted the crypt as a payment.
The consulting firm L Plus reports that it conducted a study showing that hackers who hacked Coincheck had already managed to launder about 40% of the XEM tokens stolen from the stock exchange. Probably, their bulk was sold in darknet at unknown prices, and most of the coins, according to information from the Tokyo police, have already been transferred to bitcoins. For this amount of money it is, to put it mildly, quickly. At the time of the theft, the price of funds was $ 530 million, and now ~ $ 230 million. In many respects, this drop was caused by a break-in. Coincheck itself already announced the start of compensation payments for the affected users.
The popular currency exchange Binance announced the beginning of the development of its own blockchain. After the completion of the addition of components such as Binance Labs and Binance info to its own ecosystem, the company began work on Binance Chain. Little is known so far: the development wants to focus on simple use, liquidity and productivity, the internal coin of the exchange (Binance Coin) will receive an upgrade to match the block, and the stock exchange itself was promised to gradually turn from the company into a community community. Good luck and waiting for details.
The Reddit user said that Coinbase made a serious error in the implementation of SegWit, without updating the protocol BIP70 to support SegWit-addresses. When paying for merchant services through the coinbase.com gateway, they will not receive the funds, because they will be lost due to incompatibility with SegWit-addresses, and as the company does not have merchant support services, no one will solve the problem. Well, what can I say: this is Coinbase, we wait (most likely for quite some time) fixation.
In mid-November, the hardfork of bitcoin (SegWit2x) was due to take place, but the leaders of the companies leading the initiative decided to abandon this idea. As they say in their address, the implementation of the hardfork without the consent of the community would lead to a split in the mining capacities and, as a result, the emergence of competing blockchains
HardFork is the division of the cryptocurrency into two chains by changing the processing rules and adding blocks. After the hardfork, one branch works with nodes that support the new rules, and the second – with nodes that refused to support the changes.
Since the advent of bitcoin-blockchain has gone through a lot of hardforks. Some of them did not gain popularity for one reason or another (lack of support, bugs in the software), for example Bitcoin Unlimited, Bitcoin Classic, Bitcoin XT.
In today’s article, we will recall all the important hardforks: who, when and for what purpose, tried to “divide” bitcoin-network.
In early December, 2017, the names of the first official bitcoin-billionaires became known, which do not hide the fact of their condition. They were the twins Cameron and Tyler Winklewossy, familiar to everyone who watched the film “Social Network” about the history of Facebook. In the film, the rowing brothers (members of the Olympic Games in rowing) from Harvard are not shown in a very favorable light, but in fact they are quite advanced guys.
The brothers began to buy bitcoins in 2012, when they cost less than $ 10. But they made the main investment in 2013, buying about 120,000 BTC (1% of the total issue). For this investment, they used several million of the $ 65 million received on a claim against Facebook (which copied their idea of a ConnectU social network). Consideration of the claim took place in 2008, but the brothers forced the plaintiff to pay the world not with money, but with shares. So they were able to get money only after Facebook went to an IPO. Even then, the far-sightedness of the athletes from Harvard was evident.
Charlie Lee, former Coinbase technical director, sold all of his savings in the Litecoin (LTC) crypto currency he founded in 2011. Initially, the idea was to supplement gold (Bitcoin) with a kind of silver (Litecoin), with a lower price, easier mining and transactions.
Motives for such an act, Charlie Lee explained to Reddit. The main reason is a conflict of interests. The founder of the crypto currency says that he is sick of the situation when everyone is catching every word of him, and then they are accused. Whatever he says, these words affect the price of lightcoin. The price decreases or rises, and then accusations of market manipulation begin. It got to the point that some accused that Charlie does it for mercenary purposes, because he himself is in a short position. Because of the fact that he, as the owner of LTC’s largest capital, had too much influence.
Recently, Bitcoin has witnessed a rather remarkable event. A block was obtained in which the premium 12.5 BTC per block turned out to be less than the premiums for transactions 13.4 BTC. Of course, such situations occurred earlier as a result of errors, generosity, or different experiments on Blockchain, but for the first time such a situation was the result of a trend in the cost of transactions.
Perhaps Bitcoin requires banks or their counterparts?
We continue to deal with various wallets for cryptocurrency. Last time I did a bit of digging in software wallets, and today I’ll tell you a little about the hardware. At the beginning a small reminder.
Under the wallets in cryptocurrencies understand at the same time:
- set of keys for access to money;
- programs that manage these keys and allow you to conduct transactions on the crypto currency network.
In order not to be confused when we talk about the key set, I will use the term “private key”. Although we all understand that in the key pair there is also an open pair, and also that the pairs themselves can be several.
We will talk about the wallet exactly as a means of managing, storing and conducting transactions. Without a wallet, you cannot receive, save or spend your bitcoins or funds in another cryptocurrency. The wallet is your personal interface to a cryptocurrency network, similar to a bank account for a currency.
So, hardware wallets. Let’s start with the definition. Hardware wallets are physical devices designed to safely store cryptocurrency. Some software and online-wallets support the storage of funds on hardware wallets.
Before we start comparing specific models of hardware wallets, let’s see what most of these wallets are able to do, and we will dwell in detail on the features of each of them.
