Fed's Powell Headlines Virtual Jackson Hole Economic Conference
August 26 2020 - 08:29PM
Dow Jones News

By Nick Timiraos

No need to pack bear spray this year.

The coronavirus has scrapped the Federal Reserve Bank of Kansas City's annual retreat of global central bankers in the mountains of Jackson Hole, Wyo. Instead, the event will be conducted online, viewable by the public via live stream, for the first time since the symposium began in 1978.

Fed Chairman Jerome Powell's keynote address on Thursday morning, at 9:10 a.m. Eastern time, is the main event. He is expected to reveal conclusions of the central bank's review of its monetary policy framework.

Officials have signaled they are ready to adopt a new approach of making up for periods of low inflation by seeking subsequent periods of higher inflation, and Mr. Powell's speech offers a natural venue to explain what the Fed is preparing to change and why. The practical effect is that it will be a long time before the Fed raises interest rates.

Mr. Powell announced the review in November 2018, animated by concerns that the inflation framework guiding the Fed's rate strategy for the last three decades needs to be updated for a world in which the biggest challenge isn't the runaway inflation of the 1970s but rather the difficulty of spurring faster growth when interest rates can't be cut. The problem of very low interest rates has bedeviled central bankers in Japan for the last two decades and in Europe for much of the last decade.

The primary vehicle for the Fed to formalize these changes will be to amend its statement of longer-run goals and policy strategy, which was first adopted in 2012 when the central bank established a 2% inflation goal. Inflation has generally run below the target, which has led officials to grow more concerned about periods of too little inflation.

The current shock is far more severe than any hypothetical downturn Fed officials had in mind when they initiated their review. Looming in the background of this year's conference is a troubling prospect.

While the Fed and other central banks have proven they can prevent financial panics by providing massive infusions of cash to keep markets from seizing up, their ability to spur a faster recovery is an open question. They face greater limits given the low level of interest rates, institutional constraints designed to limit explicit coordination with fiscal authorities and, in the U.S. for the moment, political disputes over the need and use for further government spending.

Thursday's session includes presentations of two academic papers, one examining slower rates of business formation and another looking at the long-term effects of behavioral changes resulting from the pandemic.

At 11:15 a.m. Eastern time, three central bankers will discuss crisis management during the recent virus shock: Philip Lane, chief economist at the European Central Bank; Bank of Canada Gov. Tiff Macklem and Tharman Shanmugaratnam, chairman of the Monetary Authority of Singapore.

Friday's session begins with a speech by Bank of England Gov. Andrew Bailey at 9:05 a.m. Eastern time, which will be followed by presentations of two more academic papers. One examines how economic agents form their expectations, and another looks at how economic uncertainty is likely to impede the recovery from the current downturn.

The second day concludes with a panel at 11 a.m. Eastern time on post-pandemic monetary policy and the prospect that interest rates can't be lowered because they are at their so-called effective lower bound. The panelists are Laurence Boone, chief economist at the Organization for Economic Cooperation and Development; Jordi Galí, an economist at the Universitat Pompeu Fabra in Barcelona; and Michael Woodford, an economist at Columbia University.

‘High’ Severity Bug in Bitcoin Software Revealed 2 Years After FixWilliam Foxley

Updated Sep 9, 2020 at 13:58 UTC

https://www.coindesk.com/high-severity-bug-in-bitcoin-software-revealed-2-years-after-fix

A previously undisclosed vulnerability in the Bitcoin Core software could have allowed attackers to steal funds, delay settlements or split the largest blockchain network into conflicting versions had it not been quietly patched two years ago.

That’s according to a paper published Wednesday by Braydon Fuller, a protocol engineer at crypto shopping site Purse, who caught the vulnerability in June 2018, and Javed Khan, a core developer of the Handshake protocol.

The vulnerability was given a severity level of 7.8 on a scale of 1 to 10, which is deemed “high” (9 or above is considered “critical”). It was caused by “remote nodes” failing to clear invalid transactions from their memory, Khan told CoinDesk.

The inability to clear those transactions could lead to an aggressor flooding a victim node with stale data in what is referred to as “uncontrolled resource consumption,” eventually causing the node to shut down, the paper states.

“There was no mechanism to make sure that the pending details of a transaction are valid or not. In certain cases you could fill up the remote memory with invalid transactions,” Khan said.

No attempt to take advantage of the hole was found in the wild, Khan and Fuller wrote. The vulnerability could not be disclosed publicly for over two years as node operators took longer than expected to update, Fuller said.

While the vulnerability was fixed, its disclosure highlights the difficulties of building a global money standard on programming languages created by humans, not to mention the high technical barriers to engaging in development of the top cryptocurrency.

The vulnerability was introduced to Bitcoin Core in November 2017. Some 50% of Bitcoin nodes at the time were exposed to the attack vector, according to the paper. Earlier versions of Bitcoin Core were not affected.

Bitcoin Core and more

Khan further said that the vulnerability could have enabled an attacker to steal funds from nodes that had open channels on the Lightning Network, an experimental payment system built on top of the Bitcoin blockchain.

Bitcoin Core versions 0.16.0 and 0.16.1 were affected and patched by developer Matt Corallo following Fuller’s disclosure to the core team in July 2018. Corallo did not answer questions seeking comment by press time.

The discovery by Fuller (who has also worked as lead developer at decentralized cloud storage protocol Storj) was followed by another Bitcoin bug addressed two months later in Bitcoin Core 0.16.3. Also a vector for a denial-of-service attack, one aspect of that bug allowed miners to “inflate the supply of Bitcoin” as they could double-spend certain values, the Bitcoin Core team wrote at the time.

The emergency patch issued in that Bitcoin Core version addressed Fuller’s bug as well, Khan and Fuller wrote.

A spot was reserved for the resource consumption vulnerability on the National Institute of Standards and Technology’s Common Vulnerabilities and Exposures (CVE) registry as CVE-2018-17145 in 2018, but it has yet to be filled out. The registry acts as a public glossary for software bugs of note.

Bitcoin Core is the reference implementation, or standard version of the network software from which others are derived. According to the paper, the exploit was also possible on several other implementations of Bitcoin and its offshoots:

* Bitcoin Knots v0.16.0

* All beta versions of Bcoin up to v1.0.0-pre

* All versions of Btcd up to v0.20.1-beta

* Litecoin Core v0.16.0

* Namecoin Core v0.16.1

* All versions of Dcrd up to v1.5.1.

All of these implementations have been patched.

UPDATE (Sept. 9, 13:30 UTC): Added a link to the paper and a more up-to-date company affiliation for Braydon Fuller.

Bitcoin adoption in Nigeria soars as central bank blocks remittances in Naira
OSATO AVAN-NOMAYO
52 MINUTES AGO


The Central Bank of Nigeria’s “Naira defense” policy is pushing more Nigerians toward Bitcoin and crypto adoption.

https://cointelegraph.com/news/bitcoin-adoption-in-nigeria-soars-as-central-bank-blocks-remittances-in-naira

Peer-to-peer Bitcoin (BTC) volume in Nigeria continues to rise as Africa’s largest economy remains a bastion for crypto adoption. According to Quartz Africa, data from the Bitcoin P2P marketplace Paxful show the country ranks second only to the United States in trading volume.

Since 2015, Nigerians have traded over 60,200 BTC on the Paxful platform amounting to about $566 million in volume over the period. Data from Coin Dance shows trading activity for the week ending Dec. 12 at 886.3 million naira (about $2.3 million).

Bitcoin’s growing appeal among Nigerians is likely due to a confluence of factors, chief of which are stringent forex policies by the Central Bank of Nigeria (CBN) as well as the rapid decline of the country’s fiat currency — the naira. In a communique issued on Dec. 16, the CBN directed international money transfer operators (IMTOs) to cease processing diaspora remittance payments in naira.

According to the central bank, the move is in line with the new policy of allowing Nigerians to receive international payments in their domiciliary accounts. The central bank also issued a notice declaring that two IMTOs — TransferWise and Azimo were not authorized to operate in the country.

While the CBN may be reversing some of its more stringent forex micromanagement policies, the scarcity caused by these previous banking laws seems to have pushed more Nigerians into alternative currencies. Indeed, Bitcoin adoption tends to soar in countries facing rising inflation and declining confidence in the national fiat currency.

With a median age of 18 years, Bitcoin likely offers an alternative for the tech-savvy young population against the mainstream banking and finance architecture under the control of the government. During the October protests against police brutality as the government ordered banks to freeze the accounts of the movement’s backers, protestors switched seamlessly to BTC and crypto donations.

According to data from Google Trends, Nigeria is still number one in terms of global search interest for Bitcoin. However, regulatory clarity for the crypto and blockchain space is yet to materialize in the country.

Back in September, the Nigerian Securities and Exchange Commission (SEC) announced plans to create a regulatory framework for cryptocurrencies in the country. At the time, the Commission declared that it would regulate crypto assets as securities unless proven otherwise.

Trading Bitcoin in Africa Is a Way for Some to Escape Poverty
Alyssa Hertig
Jan 21, 2021 at 9:34 a.m. EST
Updated Jan 21, 2021 at 9:49 a.m. EST

Learning to trade bitcoin has become a valuable skill set for Africans looking to boost their income.

https://www.coindesk.com/trading-bitcoin-escaping-poverty-africa-nigeria

For years, Stephen Aluko lived “hand to mouth” in Nigeria, home to a big but struggling economy in Africa with a high unemployment rate. He worked odd jobs, from running cyber cafes to “soft media” and videography, constantly mulling in the back of his mind if he would be able to pay for his next meal.

He was unemployed before hearing about bitcoin (BTC, -8.24%) in 2017. At that point, his shoes hardly held together.

When Aluko decided to commit to trading bitcoin – buying and selling the cryptocurrency for profit – that all changed. At first he had second thoughts. He didn’t know what he was doing. But the side hustle worked out so well he’s now been trading the largest cryptocurrency full time for three years.

“My finances were not in a good state when I started trading, so you could say bitcoin trading saved me,” Aluko told CoinDesk. “I have made enough money from trading bitcoin that I have been able to get married and can live comfortably without any debts.”

This is one example of someone using bitcoin in an unanticipated way to improve his life. And there are many other examples around the world, from Argentina to Iran.

“The money I have made from bitcoin trading has made it possible for me to invest in other businesses, be financially independent and live debt-free. So, I do think I have made more money with bitcoin than if I had chosen another career path,” he said.

The recent bitcoin bull run didn’t have anything to do with Aluko’s success. CoinDesk talked to Aluko about the rise of bitcoin trading in Africa in August 2020, before the price of bitcoin surpassed its previous all-time high, launching into a bull run.

27% unemployment

Aluko knows plenty of other traders who found themselves in a similar position.

“It’s not unique to me,” he said. “I know many people in Nigeria [who] trade bitcoin as a way to earn a living. I have also taught people how to trade bitcoin because I know how bitcoin trading has changed my life and I want to be able to help people.”

He argues that one factor driving so many people to trading is the high unemployment rate in the region. The situation has only gotten worse since Aluko was unemployed. In Nigeria, for instance, the unemployment rate has tripled over the past five years, swelling to 27%.

“Let’s just say that the numbers are not encouraging. There’s a chance that if I had worked hard and done a lot more applying to companies I may have gotten a decent job. But when I think about what I have achieved in three years as a result of trading bitcoin I am sure that I made the right choice,” Aluko said.

Other Africans have made the same career decision, giving bitcoin and cryptocurrency trading a try. African exchange Quidax CEO and co-founder Buchi Okoro said this is one of the key reasons people use the exchange.

“From our conversations with our customers, we have a lot of people using crypto to earn a living by trading as a full-time job,” Okoro told CoinDesk.

Bitcoin trading vs. speculation

Then there’s speculation, which is a bit different from trading. Speculation is investing in a risky asset, such as cryptocurrency, with the hope the price will go up and enrich the investor.

“Though bitcoin is used for speculation universally throughout the world, it hits differently in Africa,” KenyaCoin, a pseudonymous bitcoin enthusiast from Kenya, told CoinDesk, pointing to unemployment rates, as Okoro had.

“There are huge numbers of university graduates who simply cannot find employment in the country. Those with the means, especially those who studied economics, finance or tech, take up speculation in the crypto space to either try to supplement whatever income they do have or as a substitute for ’employment,'” he added.

KenyaCoin guesses that speculation is “the number one activity involving bitcoin and crypto on the continent.”

Risk of bitcoin and crypto scams

The rise of bitcoin and crypto in Africa has not necessarily been all rainbows, however.

There’s a dark side to this trend, too. Some people have gotten hurt from trading and speculation. Much like the rest of the world, as Africans have explored cryptocurrency as a route to a better income, some have lost money or have fallen for a number of scams.

Many Nigerians, for instance, first heard about bitcoin through MMM, a Russian Ponzi scheme that promised investors 100% returns. When MMM didn’t fulfill these lofty promises, participants lost their money.

KenyaCoin pointed to infamous cryptocurrency scams BitClub network and Onecoin as other examples of “bad” projects that have flourished in the region, as well as lesser-known scams such as Nurucoin and Crowd1.

“Scams often target victims in developing countries, as regulations in the finance and investment space are not always solid and/or enforcement is oftentimes lagging,” he said.

Bitcoin and other cryptocurrencies are still new so people in Africa – as well as the rest of the world – are still getting a handle on which cryptocurrency projects are actually useful for them rather than harmful.

CONGOLESE REFUGEES USE BITCOIN TO BUILD GRASSROOTS ECONOMY
After the eruption of Mount Nyiragongo volcano on 22 May 2021, a restaurant worker and a blogger teamed up in the city of Goma, Democratic Republic of Congo and taught displaced families how to use Bitcoin.
ALEX MCSHANE

After the eruption of Mount Nyiragongo volcano on 22 May 2021, a restaurant worker and a blogger teamed up in the city of Goma, Democratic Republic of Congo and taught displaced families how to use Bitcoin, TechCrunch reported.

Blogger Gloire Wanzavalere went to a refugee camp that popped up in Goma, offering to give Bitcoin to displaced families. Gloire told TechCrunch that he discovered most of the families had traded what few belongings they had managed to escape with, thus they did not have the paperwork required to open bank accounts or acquire phones.

“These people lost everything. I understood it was rational for them to sell what they had left in order to buy food,” Gloire told TechCrunch. “So we bought phones for eight people…twelve people benefited from our initiative, four among them already had their own smartphones.”

Wanzavalere was inspired by news of the Bitcoin Beach circular economy in El Salvador, which he evidenced as proof poor people can use Bitcoin.

“Coming to their aid with bitcoin was a more powerful act than any marketing campaign could be. That’s when we told ourselves, OK, we’re going to do this in Congo,” the blogger said.

Gloire’s mother owns a small shop in Goma. She agreed to accept bitcoin using her mobile phone through apps like Wallet of Satoshi and Phoenix Wallet.

“Because she is very excited about the idea of helping people with bitcoin, she is considering the option of bringing a few essential goods closer to the refugees, so they can buy what they need without going too far into town. But it’s a complex question in part because of security concerns,” Wanzavalere said.

Juvin Kombi spent the past summer setting up the first Lightning Network node for Jikofood Restaurant, where he works. This allowed Jikofood to accept Bitcoin without high transaction fees nearly instantaneously. By September Kombi’s node was running, and the restaurant was accepting payments on the restaurant’s PC and sometimes employees own personal smartphones. Their preferred mobile wallet apps are Muun Wallet and Blue Wallet.

“The learning process was very long, but the minimum research we have done has helped us understand bitcoin without any support,” Kombi told TechCrunch. “We realized that it was easy to set up. A simple wallet and an internet connection are sufficient. In addition, we are studying the possibility of setting up BTCPay Server in the near future.”

At the moment only a handful of the restaurant’s clients use itcoin, Kombi added, including the displaced people Gloire hired. But the staff hopes that the knowledge about Bitcoin as a method of savings and payment option will spread among the community. Jikofood even hosts educational Bitcoin workshops for customers.

“The Congolese population is suffering greatly; it never had any stable currency except the U.S. dollar,” Gloire commented. “I am not a journalist. However, I started to write about bitcoin issues in Africa because there was a lack of information on the subject in French.”

As he wrote Gloire fundraised for this grassroots program by inviting Bitcoiners abroad to participate in a “Lightning Torch.” He would invite anyone online through a Tweet to join a chain of Lightning Network transactions by sharing an invoice and sending small amounts of bitcoin to pay it forward to the next invoice holder. Even Jack Dorsey, the CEO of Twitter participated, TechCrunch reported.

“In total, 18 people contributed,” Gloire said. “In less than three hours, all the beneficiaries mastered it, learning how to receive and send money using a bitcoin wallet, which shows that in practice the Lightning Network isn’t that complicated to use.”

“We plan to raise more money to help an even larger part of the suffering population,” Gloire concluded. “The money collected by the torch event was meant to be distributed without anything in return. However, this is a long-term idea. Paying the refugees in bitcoin for freelance work could be a source of more community engagement.”

Gloire plans to teach the refugees how to run a lightning node, just like the Jikofood Restaurant, with hopes of expanding the local Goma Bitcoin economy, giving financial power back to small businesses, and banking the unbanked.
