Abkhazian authorities will intensify efforts to identify illegal mining farms

The authorities of Abkhazia plan to strengthen activities to identify illegal mining farms, as well as to limit the supply of electricity due to heavy loads on the electricity grid.
This issue was discussed at a meeting in the Cabinet of Ministers of Abkhazia on the current state of electricity networks in the region. According to the head of RUE "Chernomorenergo" Aslan Basaria, the company is forced to temporarily limit the supply of electricity to some regions of the Republic.
He added that at the moment the indicators of electricity consumption exceed 40 MW, which may be due to the uneconomical use of electricity and the constantly growing number of illegal farms for mining, which are connected to the networks of Chernomorenergo.
During the meeting, Prime Minister of Abkhazia Valery Bganba instructed to develop legal acts to determine the limitation of electricity consumption "Chernomorenergo" for each consumer, as well as to take additional measures to identify illegal mining farms.

Cryptocurrency startup Circle has cut another 10 employees

The cryptocurrency company Circle has undergone another wave of cuts – as part of the optimization of business processes, 10 more employees were fired.
A week after it was announced that Circle co-founder Sean Neville will leave his post by the end of the year, the company announced the reduction of another 10 employees.
"As we continue to focus on advancing our stablecoin-related business strategy, we have simplified some departments and reduced about 10 positions," a Circle spokesperson said.
Earlier in may, the company had already laid off 30 employees, citing regulatory concerns and market conditions. Then the cuts affected about 10% of the staff.
Recently, Circle announced that it will charge commissions from American users who did not have time to withdraw cryptocurrencies from the Poloniex exchange before December 16, as part of the separation of the site from the parent company and its departure from the United States.

Waves introduced Gravity Hub solution for interaction of different blockchains

The Waves platform introduced a new gravity Hub solution aimed at improving the interaction of various blockchains and decentralized applications, as well as efficient data acquisition.
Waves management announced this at a community conference in Berlin, adding that there will be no tokens on the Gravity Hub blockchain, but it will interact with other blockchains such as Waves Platform, Waves Enterprise or Ethereum.
Gravity Hub will work as a data Oracle, performing the transfer of information from the outside world to the blockchain. Members of any network will be able to request data from Oracle from any information system with API - from Google to enterprise ERP systems.
Interaction will occur not only at the Protocol level, but also at the level of decentralized applications – a request can be transferred from one application to another, even if they operate on different blockchains. For example, gravity Hub nodes will be able to receive block headers from the Ethereum network and send them to the waves platform.
If the data on the received header will be present on the waves platform, it will serve as proof that a certain transaction was performed in Ethereum. Token transfers between blockchains will be carried out using ports that also use data from Gravity Hub.
Given that the nodes will be divided into a main core and several mandatory and optional plugins, users will be able to choose smart contract languages, consensus algorithm modules, cryptography types, and other features. The validity of Gravity Hub data is achieved by consensus between multiple nodes.
According to Waves, the inability to transfer data from one blockchain to another hinders the development of new technologies, but the gravity Hub solution can take them to a new level, providing "free communication" between blockchains.

Binance launched a crypto-Fiat platform for Latin America

Cryptocurrency exchange Binance with the participation of the Settle Network launched a new crypto-Fiat platform Latamex for Latin American users.
At the laBitConf conference in Montevideo, Binance said that users will be able to directly buy BTC, ETH, BNB and BUSD stablecoins for Argentine pesos and Brazilian reals. Payments will be made through the Latin American digital asset sales network Settle Network.
First, the new platform will be presented in Brazil and Argentina, but the official website of Latamex has already published a list of countries in which the platform will operate in the near future: Mexico, Uruguay, Colombia, Panama, Costa Rica, Dominican Republic, Guatemala, Honduras, Nicaragua, El Salvador, Paraguay, Peru and Chile.
"Latin America is in dire need of cryptocurrencies-half of its population does not provide banking services. Cooperation with Settle Network will simplify the purchase of cryptocurrencies for Latin American traders. In the future, we will support other local Fiat currencies in the region, " - said the CEO of Binance Changpeng Zhao.
He also added that most of the world's finances are still in Fiat currencies, so the large-scale introduction of cryptocurrencies around the world requires the creation of Fiat gateways. In November, Zhao said he intended to add support for all 180 Fiat currencies in the world.

New York Department of financial services to review BitLicense terms for token listing

The New York Department of Financial Services (NYDFS) is developing rules to regulate token listing as part of the first step in revising new York's BitLicense license.
Department superintendent Linda Lacewell shared details of the plan, which will be implemented as a first step. The proposed regulatory guidance will specify which tokens are allowed to be listed by BitLicense owners. NYDFS also wants to develop a regulatory document on which cryptocurrency exchanges will be able to rely in the process of forming a policy for listing tokens.
Companies that already have a BitLicense license will have to provide the appropriate policies to the regulator for approval. They need to specify methods to address the risks associated with asset management and monitoring of actions with it
The current terms of the NYDFS suggest that the regulator must approve each cryptocurrency before adding it to an exchange that serves new Yorkers. After the introduction of the new rules, the Department will only need to approve the listing of an asset once, and then all other sites will be able to add it to their trading platform without first contacting NYDFS.
"New York is a center for innovation and consumer protection. We have to take into account the pace of development of the financial services industry and adapt to them, - says Laswell. – This step is very important in the context of the revision of the virtual currency regime. It aims to simplify the procedure of listing new coins in existing products of those companies that have already received a license in new York."
The next step will be to collect comments on the new proposal. This stage will last until January 27 next year.
Today, 24 companies have a valid BitLicense. At the same time, some participants in the cryptocurrency industry decided not to apply for a license and leave new York, believing that the requirements of the regulator are too strict.

CoinShares: Chinese BTC miners produce up to 66% of the global hash rate

According to the study, Chinese bitcoin miners still control up to 66% of the global hashrate, with most of the farms concentrated in one province.
According to a research by the British company CoinShares, BTC miners from the Chinese province of Sichuan account for more than half of the global hashrate. According to the report, China's share of global hashrate rose from 60% in June 2019 and has now reached the highest recorded by CoinShares since 2017.
While Sichuan accounts for more than 50% of the global hashrate, the other largest mining centers are the Chinese provinces of Yunnan, Xinjiang and Inner Mongolia. Other large mining enterprises are located in the United States, Russia and Kazakhstan, notes CoinShares.
Head of research CoinShares Chris Bendiksen suggested that the recent growth of hashrate in China was the result of the spread of more advanced equipment for mining.

BitMEX has added support for the Bech32 address format for BTC output

BitMEX exchange now allows its customers to withdraw BTC from their accounts using all three bitcoin address formats-P2PKH, P2SH and Bech32.
In a blog post, BitMEX explained that Bitcoin uses three address formats: P2PKH (the original Bitcoin address format, addresses start with "1"), P2SH (the address format available since April 2012, addresses start with "3") and Bech32 (segwit's own address format, addresses start with "bc1").
The record then States that although it is now possible to withdraw BTC to addresses of any of these three formats, customers still need to make deposits to BTC using the P2SH format due to the exchange's "multi-signature wallet" solution. Thus, the Bech32 address format can only be used to output BTC with BitMEX.
In a blog post, BitMEX summarized the benefits of Bech32 addresses: more efficient use of block weight (and thus lower fees), improved error detection system, and more efficient QR codes. BitMEX notes:
"Thus, this innovation will not directly lead to lower fees when withdrawing BTC from BitMEX, however, in the next transaction, when bitcoin is used, already withdrawn from BitMEX, our customers can benefit from lower transaction fees."
BitMEX says that in the future it plans to update its "current multi-signature wallet solution that does not support SegWit" and make it possible to enroll bitcoins from Bech32 addresses.

Netherlands will toughen penalties for cryptocurrency-related crimes

A new bill by the country's Ministry of justice and security aims to bring penalties for fraud using these new payment methods in line with enforcement actions for crimes involving traditional payments.
For credit card fraud in the country faces up to 6 years in prison, while the current terms for a similar crime with banking applications and cryptocurrencies are from one to four years, according to NL Times.
In addition to cryptocurrency and payment applications, the publication lists account-sharing applications that could also be included in the scope of the law being drafted by justice Minister Ferdinand Grapperhaus. According to another report, the bill is based on the EU anti-money laundering Directive.
Grapperhouse said fraud using new payment methods is becoming more common and can affect a large number of people. The Minister noted that the introduction of stricter penalties will serve as a deterrent.
The new sentencing regime will apply to crimes such as payment fraud, possession or sale of falsified data, credit card fraud and phishing schemes.
It was reported in September that cryptocurrency organisations based outside the Netherlands could be banned from operating in the country under new regulation to be adopted early next year. Recall that the Central Bank of the Netherlands will begin to regulate cryptocurrency companies from January 2020.

Anonymous Lightning Network developer will receive grant from Square Crypto

The cryptocurrency division of payment company Square announced that the developer of Lightning Network for the Bitcoin network will receive a grant from the company to continue the work.
We are talking about a user under the pseudonym ZmnSCPxj. He is known for his high-quality and fruitful comments on proposals to improve the Bitcoin network, as well as his own proposals. The grant should help the user to quit the hired work and devote himself to the development of Lightning Network.
"This cannot be imagined in any other field. We give a grant to a person under a pseudonym that looks more like a hash function. We really don't know who ZmnSCPxj is or where he lives. All we know is that he lives in the GMT+8 time zone, which includes parts of China, Hong Kong, Brunei, Macau, Taiwan, the Philippines, Malaysia and Singapore. That's all. That's all he told us and that's all we know, " representatives of Square Crypto emphasize.

In addition, Amato is trying to sue the site for $250 million in moral damages. The main accusation of Amato and RGB Coin is that the BitMEX exchange and its CEO Arthur Hayes deliberately misled investors and illegally seized their funds

The liquidator of the Cryptopia exchange was able to recover $7.2 million of the $16 million stolen by hackers

Exchange liquidator Grant Thornton New Zealand has released a report detailing the balance sheet of recovered assets and the challenges the company faces.
Overall, from may to November, the company received $10.9 million in new revenue, including $5 million from a third-party trust Fund, $4.4 million converted from the exchange's 344 BTC, and $200,000 from the sale of assets-furniture and equipment from The cryptopia office.
However, expenses related to the ongoing liquidation process amounted to $3.7 million, including payments to first-line creditors, salaries, legal expenses and liquidator commissions. Thus there is $7 164 835 million in assets that can potentially be used to compensate users.
While the user compensation process is reported to be "well under way," the report also highlights the complexity of the operations that need to be performed to determine the amount of payments to each user.
As the company notes, it is extremely difficult to determine the balance of each asset That cryptopia customers owned, since customers did not have individual wallets, and crypto assets were instead stored in shared wallets
In addition, the exchange has not completed the verification of its client databases with cryptocurrencies actually in its wallets, leaving "time-consuming work" to find out the balance of each client.
Also a potential obstacle to possible payments was the fact that legal issues had to be resolved first. The liquidator appealed to the Supreme court of New Zealand for clarification of the legal status of crypto assets in the country.
As Grant Thornton notes, the court's decision on whether crypto assets are considered property or not will determine whether they can be managed by proxy or whether the company retains pre-emptive ownership. The next mandatory liquidator report must be submitted by may 2020. The company also plans to release an updated version of the report after a court hearing in February.
The liquidation process of cryptopia exchange was started in may and soon after the exchange filed for protection from prosecution by creditors under the bankruptcy law in the United States. According to Elementus research, Cryptopia lost $16 million as a result of the hack.

Leo Zhang: "miners need to think through the business due to the imminent halving of the reward»

According to the Chairman of Iterative Capital Management Leo Zhang, miners need to think carefully about the business, as in six months will be upolovinivanie awards for mining.
Zhang stressed that although many analysts believe in the rise of the bitcoin rate after halving the reward for mining, in fact, no one knows what will happen. Despite all the Analytics, the bitcoin rate is closely related to the hashrate of the network and in case some miners leave the industry after the half of the reward, the price of bitcoin may even decrease.
At the same time, according to a study by Iterative Capital, after halving the reward for mining, the bitcoin rate will exceed $17,000. Now, using Whatsminer M20s devices and paying 3 cents per kWh for electricity, the cost of bitcoin mining is $7,000. Accordingly, if miners produce half as many bitcoins, the cost will reach $14,000, and if the electricity fee rises to 7 cents per kWh, the cost will exceed $17,000.
The Chairman of Iterative Capital Management has highlighted several ways for miners to remain profitable. However, there will be no revelations: you need to buy equipment at a minimum price, as well as try to reduce the cost of electricity and other operating costs. At the same time, companies need to provide themselves with a supply of electricity, or money, so that in case of a possible decline in the rate of bitcoin, they can survive this drawdown.
"In fact, there is no truly effective way to hedge these risks. All you can do is cut your costs as much as possible, " Zhang concluded.

Kraken Security Labs discovered a vulnerability in the cryptocurrency wallet KeepKey

Employees of the research company Kraken Security Labs discovered a vulnerability in the hardware cryptocurrency wallet KeepKey, through which attackers can gain access to the user's assets.
The researchers reported that, having physical access to the device, an attacker can extract an encrypted seed-phrase protected by a PIN code that contains 1 to 9 digits, since such protection is broken by a simple brute-force of passwords. However, it is not possible to eliminate the vulnerability, because KeepKey needs to change the wallet at the hardware level.
"An attack called "voltage failure " is made on the microcontroller used in KeepKey wallets. With the help of certain malicious manipulations with the power it is possible to affect the first element of the software loaded by the device, in this case, "BootROM code", - said Kraken Security Labs employees.
You can build a device that can carry out such an attack for about $75, but the researchers told how users can protect themselves from hacking. First, you need to try to ensure that no one except the user has physical access to the device. If the user loses the device or is kidnapped, this vulnerability can be used to access cryptocurrency assets.
Cybersecurity experts also recommend adding the BIP39 passphrase through the KeepKey Client extension. This passphrase is a bit awkward to use, but is not stored on the device and is therefore not vulnerable to attack. The researchers noted:
"Despite the fact that the bulk of The keepkey codebase is based on Trezor One, they still have differences. KeepKey developers added several mechanisms that were supposed to make the wallet firmware immune to crash attacks. At the Wallet event.Fail has been demonstrated similar attacks, but it turned out that all these measures are ineffective."
