The U.S. Congress Subcommittee on Terrorism and Illicit Finance has discussed various methods of terrorism financing with cryptocurrency, according to an official press release on the U.S. House of Representatives Financial Services Committee September 7.

In order to monitor threats and methods of terrorist financing, the hearing considered major means of transferring funds by terrorists, including traditional financial institutions and semi-formal methods, such as the hawala exchange system, as well as cryptocurrencies.

However, while al-Qaeda, the Islamic State, and other terrorist groups have all attempted to raise funds through crypto, they have not had great success, as Congress  concluded in the meeting.

Yaya Fanusie, director of analysis for the Foundation for Defense of Democracies (FDD) Center on Sanctions and Illicit Finance, stressed that most terrorists, especially those that serve on “jihadist battlefields,” are currently living in environments where crypto is not operable, which means that fiat use is preferable for buying goods.

Fanusie pinpointed fiat money as the most anonymous method for funding, claiming that it is very popular among terrorists.

While Fanusie stated that crypto is a “poor form of money for jihadists” and “cold hard cash is still king,” according to a Forbes article, he still acknowledged that “there are multiple examples of terrorist cryptocurrency funding campaigns.”

The expert further stated that in order to combat the potential successful use of crypto fundraising campaigns by terrorists, the U.S. government bodies that are responsible for terrorist finance investigation should become more skilled in analyzing cryptocurrency transactions. Fanusie noted:

Goldman Sachs Chief Financial Officer (CFO) Martin Chavez said that recent reports about the company abandoning its plans to open a cryptocurrency trading desk are “fake news,” CNBC  reported September 6.

At the TechCrunch Disrupt Conference in San Francisco, Chavez reportedly said that reports about the company’s intentions for a crypto trading desk were unfounded:

"I never thought I would hear myself use this term but I really have to describe that news as fake news."

Rumors that Goldman Sachs planned to establish a crypto-focused unit by the end of 2018 were initially reported by Bloomberg in December last year. However, on September 5, Business Insider reported that unnamed sources said the firm is scrapping crypto trading desk plans due to an unclear regulatory environment in the crypto industry. Chavez suggested that the excitement over a potential trading desk may have been premature. CNBC quotes him saying:

"When we talked about exploring digital assets [...] it was going to be exploration that would be evolving over time. Maybe someone who was thinking about our activities here got very excited that we would be making markets as principal and physical Bitcoin, and as they got into it they realized part of the evolution but its not here yet."

While Goldman has been clearing and providing liquidity for Bitcoin-linked futures contracts from the CBOE and CME, Chavez said there needs to be a reliable custody solution before the bank can proceed with physical Bitcoin (BTC). He stated:

"Physical bitcoin is something tremendously interesting, and tremendously challenging. From the perspective of custody, we don't yet see an institutional-grade custodial solution for Bitcoin, we're interested in having that exist and it's a long road."

Chavez noted that the company is working on a type of Bitcoin derivative, non-deliverable forwards, which are over the counter derivatives settled in U.S. dollars. The reference price is reportedly the Bitcoin/USD price established by a group of exchanges.

The price of Bitcoin and other digital currencies plummeted following the news about Goldman Sachs cancelling plans for a trading desk, with total market cap dropping by $12 billion in an hour. All of the top 100 coins experienced losses over the last 24 hours. BTC is trading around $6,479, having lost more than 6 percent on the day. At press time, total market capitalization is around $206 billion, according to Coinmarketcap.

China’s central bank, the People's Bank of China (PBoC), is extending the activities of its Digital Currency Research Lab beyond the country’s capital, local media outlet CNstock reports September 5.

The news reveals that the lab has opened a new fintech research center in Nanjing, the capital of China’s eastern Jiangsu province. The establishment of municipal fintech centers is reportedly intended to support the PBoC’s testing of its recently developed digital currency prototype, as the bank steers the prototype to production.

The Jiangsu center has been established in partnership with the municipal government, Nanjing University, the PBoC’s Jiangsu branch, and the Bank of Jiangsu, CNstock writes.

The center aims to serve as a bridge between “politics, production, study, research and use” and to this end will pool resources from across government departments, high-tech parks, financial institutions, and universities in order to pilot cutting-edge fintech applications and promote them across the country.

As CNstock notes, the new center has been founded several months after the Digital Currency Research Lab established its fully owned subsidiary in the southern Chinese city of Shenzhen, also in collaboration with the municipal government. Shenzhen is reportedly slated to be the first city to test the PBoC’s “legal” digital currency, and to provide the systematic preparation for its launch, including cooperation with the country’s regulators.

As Cointelegraph reported yesterday, the Shenzhen Central Sub-branch of PBoC officially launched the testing phase of its blockchain trade finance platform ahead of schedule.

How Bitcoin Mining Works
Where do bitcoins come from? With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government.

With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.

Bitcoin is Secure
Bitcoin miners help keep the Bitcoin network secure by approving transactions. Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.

Has never understood the essential difference between p2p and blockchain technology, personal understanding is pure p2p technology can also be decentralized, but can not verify the accuracy of the data. The blockchain, in addition to decentralized, but also verify the authenticity of data and other issues, is it?
