bookmark_borderDev says $31 million Meerkat Finance exploit was a ‘test’; will return funds

DeFi is “flourished by human greed,” according to a developer for the exploited project

There may be good news on the horizon for the victims of one of DeFi’s largest-ever exploits. 

At 5:30 AM UTC today, a Meerkat Finance developer identifying themselves as “Jamboo” posted a short message in a newly-created Telegram channel, “Meerkatrefunds.” In it, Jamboo said that the exploit was a “trial” testing users’ greed and “subjectivity,” and that the team was preparing to refund all victims.

Jamboo provided proof of their association with Meerkat by sending a small transaction from the Meerkat deployer, demonstrating that they have access to the exploited contract (or communicates with someone who does). The transaction was processed on the Binance Smart Chain network roughly twenty minutes after Jamboo’s Telegram post.

Meerkat was a yield vault project that forked Yearn.Finance’s code — one of many forks of Ethereum-native protocols that populate BSC. The attack on Meerkat initially took place on March 4, resulting in a loss of 73,000 BNB and $14 million of stablecoin BUSD — a total of $31 million in user funds.

Members of the community were quick to label the exploit as a “rugpull” — a colloquial term for when an insider or a member of a development team exploits a contract using specialized permissions — given that the Meerkat deployer contract was updated to allow the vaults to be drained shortly before the attack.

Some thought that the exploit would be a test of Binance Smart Chain’s claim to decentralization. BSC is run by a network of 21 validator nodes, many of which are thought to be associated with or run directly by Binance. 

Likewise, the exploit put the attacker in a difficult position: Binance controls on-offramps to BSC, meaning any stolen funds were locked on the chain and impossible to realize as profits. 

Attention now turns to the Meerkat developers and their motivations. Jamboo’s message was short on specifics, and contained only vague references to what instigated the team to steal $31 million from users. Jamboo wrote that the team “invited a third party (hacker) to attack the vulnerability through the verify proxy contract,” and that a full report on the exploit will be forthcoming.

According to Jamboo, the theft was a demonstration of the avarice that pervades DeFi.

DeFi is essential, but it has a lot of flaws. It is flourished by human greed.

bookmark_borderNew York governor Cuomo reveals COVID-19 pilot built on IBM blockchain

Blockchain could play a crucial role in COVID-19 vaccination management as the globe starts to emerge from the crisis.

A sense of relief has begun to emerge as COVID-19 vaccinations continue to be administered across the world. While hopeful, a new challenge remains: distinguishing between individuals vaccinated and those unvaccinated. 

Various statistics claim that very little of the world’s population has been fully vaccinated as of the start of March 2021. While this number is still low, some regions like Texas have optimistically begun lifting mask mandates in hopes of resuming normal lifestyles. Other states across America, however, have started taking safer precautions to ensure normalcy following the COVID-19 vaccination rollouts.

For example, New York governor Andrew Cuomo recently announced a pilot program to trial the “Excelsior Pass,” a solution based on IBM’s Digital Health Pass powered by blockchain technology. According to the New York State blog post, “the Excelsior Pass will confirm an individual’s vaccination or a recent negative COVID-19 test through a confidential data transfer” between businesses in accordance with New York State guidelines.

Blockchain enables secure data sharing

Jason Kelley, the general manager for IBM Services, told Cointelegraph that New York has customized the app to meet the state’s specific needs. “Modifications are being made to address those requirements. The underlying technology is the same as IBM Digital Health Pass,” said Kelley.

The Excelsior Pass was initially tested during the Brooklyn Nets game at Barclays Center on Feb. 27. The app was piloted once again during the New York Rangers game on March 2 at Madison Square Garden. While results from these pilots are yet to be revealed, Kelley explained that the Excelsior Pass functions similarly to that of a mobile airline boarding pass:

“Individuals will be able to either print out their health pass or store it on their smartphones. A QR code is used to inform the venue if a pass is valid or invalid. The aim is to give residents the ability to digitally confirm in a simple, voluntary and secure way their proof of a negative COVID-19 test result or certification of vaccination.”

Blockchain plays an important role in ensuring user data remains private when shared with organizations that require a verified health pass. Eric Piscini, vice president of blockchain for IBM Watson Health, previously told Cointelegraph that the Digital Health Pass platform specifically uses blockchain to establish self-sovereign identity, along with verifiable credentials.

Kelley further mentioned that IBM’s Digital Health Pass runs on open standards, enabling easy interoperability with other solutions, along with access to details regarding the technology being used in the application: “IBM has built the solution using open architecture so that other states can choose to join the effort,” further stating: “This could provide the foundation for a secure and interwoven ecosystem enabling governments, businesses and people nationwide to power a safer, trusted transition to a post-pandemic reality.”

Will other regions choose blockchain as a solution?

Kelley mentioned that the goal of the Excelsior Pass is to provide New York residents with a simple, voluntary and secure method for showing proof of a negative COVID-19 test result or certification of vaccination. It’s also important to note that the pass allows New York State residents to voluntarily share their health status on their own terms without ever revealing underlying personal data used to generate those credentials.

As such, a blockchain solution could very well be the missing link to COVID-19 vaccination management offerings moving forward. It’s notable that the American pharmaceutical company Moderna recently announced plans to partner with IBM to learn how emerging technologies, such as artificial intelligence, blockchain and hybrid cloud, could help support more efficient COVID-19 vaccine management efforts. Moderna will be looking at how the Digital Health Pass can be utilized throughout the United States as a vaccine management solution.

In addition to IBM’s Digital Health Pass, United Kingdom-based asset-tracking provider Everyware is using a distributed ledger solution from Hedera Hashgraph to manage vaccine storage and administration. The Hedera base layer provides a verifiable timestamp and ordering of events across the vaccine supply chain, also allowing healthcare providers to share data with other parties involved in the delivery chain. In addition, this storage solution leverages hardware to monitor the distribution and administration of vaccines.

Brazil is also using a blockchain-based system to track individuals who have received a vaccine. Known as the National Health Data Network, this solution is powered by Hyperledger Fabric and uploads data to the blockchain once individuals receive vaccinations.

Although the use of blockchain for vaccination management is impressive, regulations may create challenges for certain regions looking to leverage such solutions.

Brian Platz, co-CEO of Fluree — a blockchain-based data management platform — told Cointelegraph that regulatory issues regarding data sharing are always subject to the specifics in implementation and infrastructure choices. However, Platz noted that verifiable credentials technologies, such as the one developed by IBM, are generally privacy-enhancing and more compliant than traditional systems:

“In many ways, verifiable credentials are better ways to accomplish data privacy because they move control over sensitive data, such as medical information, closer to the owner of that information.”

bookmark_borderThe United Arab Emirates’ green digitization vision

The COVID-19 pandemic has revealed the need for sustainable digitization of the economy, and the UAE is accepting the challenge.

The United Arab Emirates is the world’s sixth-largest oil producer and one of the richest countries in the world, with a gross domestic product per capita of above $43,000 as of 2019, according to the World Bank. As per its “Vision 2021,” Iis petroleum- and natural-gas-reliant economy is committed to sustainable development in order to emerge as the Gulf Cooperation Council’s, or GCC’s, most diversified economy. This includes the digitization of the economy, which has become a priority during the COVID-19 pandemic.

A green economy for sustainable digitization

The first virtual Abu Dhabi Sustainability Week Summit 2021 was broadcast live around the world in English and Arabic on YouTube, receiving over 100,000 views during the event from participants hailing from over 175 countries, and it featured over 500 influential global leaders from government, business and technology who explored the social, economic and technological opportunities supporting a sustainable green recovery from the pandemic.

At the summit, GCC leaders reconfirmed their decarbonization pledges “to save the equivalent of 354 million barrels of oil through the deployment” of renewable energies. This represents a 23% reduction in oil consumption to reduce the power sector’s carbon dioxide emissions by 22%, according to the latest figures from the International Renewable Energy Association.

In his opening address, Sultan Ahmed Al Jaber — the UAE’s minister of industry and advanced technology, special envoy for climate change, and chairman of clean energy company Masdar — pointed out that with the COVID-19 pandemic, society is now witnessing the implementation of artificial intelligence, machine learning and the digitization of different spheres of life all over the world. Accordingly, electrification, decarbonization and digitization initiatives have become increasingly important across all industries.

Masdar’s solar energy initiatives

New digital technologies require a high consumption of electricity, which in the UAE is currently produced predominantly using fossil fuels that adversely impact the environment. Given the UAE’s vast hydrocarbon resources, Masdar is aiming to become a major blue hydrogen producer and contribute to the nation’s efforts to cut polluting carbon emissions by nearly a quarter. Masdar recently reached an agreement with Abu Dhabi’s Department of Energy and five additional institutions to develop clean hydrogen fuel solutions.

But the UAE’s Paris Agreement commitment to zero emissions by 2050 is heavily reliant on solar energy to diversify Abu Dhabi’s energy sector into renewable sources. Solar energy is seen as an anchor to Masdar’s renewable strategies from many perspectives. In Abu Dhabi, it is building the world’s largest solar power plant, as deserts are some of the best places to harvest solar power. They are never short of sunlight and are rich in silicon — the raw material for the semiconductors from which solar cells are made. Another benefit to installing solar panels in the desert, according to a 2018 study, is that it may create a more humid environment that causes vegetation to spread to combat desertification.

Masdar City: The UAE’s aerospace and green technology zone

Developed by Masdar, Abu Dhabi’s Masdar City is one of the world’s most sustainable urban communities, offering a strategic base through which companies can build their networks locally and globally and can explore multiple investment opportunities and test innovative new technologies from inception through to implementation to help the UAE diversify its economy.

Housing a free zone area, the city has more than 900 organizations, from international conglomerates to startups, developing innovative technologies in the areas of energy, water efficiency, mobility, space, blockchain technology and artificial intelligence to address the world’s most critical sustainability challenges in more than 30 countries.

UAE Space Agency

Based in Masdar City, the UAE Space Agency contributes to supporting a sustainable national economy by developing satellites used in natural resource mapping, environmental monitoring, land-use planning and security, and it has also launched a probe to Mars.

Digital economy

The UAE government has made the digitization of its economy a priority in order to bring efficiency to government, creativity to industry, and build international leadership. To accomplish this goal, the UAE has established in Masdar City the world’s first graduate-level, research-based artificial intelligence university, Mohamed bin Zayed University of Artificial Intelligence, which welcomed its first students in January 2021.

The UAE also adopted the Emirates Blockchain Strategy 2021 and The Dubai Blockchain Strategy, which have undertaken several blockchain projects. SustVest is a crowd-investing blockchain-based platform that lets people invest in solar projects and earn returns from consumers who use their funding to install solar panels. The company is based in the Dubai Silicon Oasis Authority and has built its solution on the Nem blockchain. Its founder, Hardik Bhatia, explained:

“The global rooftop solar segment is booming with opportunities, and is valued at over $66 billion. Emerging economies are looking to transition to solar as it offers a green and cheap alternative to conventional energy sources. SustVest enables this transition in emerging economies by crowdfunding rooftop solar projects in emerging economies on its platform. We tokenize solar projects granular to the level of individual solar cells, and investors purchasing these tokens can earn dividends generated by the sale of electricity from these individual solar cells. We are opening the gates for retail investment into solar space, and we do so by tokenizing the projects to reduce the barrier of entry and creating a secondary marketplace for providing liquidity to investors.”

The Central Bank of the United Arab Emirates, along with the Saudi Central Bank, is developing a state-backed bilateral central bank digital currency, “Aber.” Aber is initially set to help the UAE and Saudi Arabia make more cost-effective bank-to-bank, cross-border payments and financial settlements using blockchain technology on a probationary basis, and according to official statements, it will be exclusively available to a limited number of banks. Eventually, Aber will be used globally on China’s blockchain-based service network, or BSN, which will support future CBDCs from various countries such as the UAE.

Crypto-asset regulations in the UAE

The UAE prioritizes blockchain and distributed ledger technology and has launched various related ventures, especially since the COVID-19 pandemic. Nevertheless, cryptocurrency regulation in the nation remains limited.

Toward the end of 2020, the UAE’s Securities and Commodities Authority, or SCA, published “The Authority’s Chairman of the Board of Directors Decision No. (21/R.M) of 2020 Concerning the Regulation of Crypto Assets.” The SCA’s decision lays out its licensing regime for anyone who wishes to offer crypto assets within the UAE, including exchanges, crowdfunding platforms, initial coin offerings, custodians, and other services that use crypto assets.

The Financial Services Regulatory Authority, or FSRA, of the Abu Dhabi Global Market considers crypto assets to have characteristics like those of shares, meaning they are to be treated as securities and are subject to information disclosure requirements related to risk and transactions. On the other hand, utility tokens and non-fiat cryptocurrencies are considered commodities and are not subject to market regulations. Law No. 20 of 2018 on Anti-Money Laundering defines laundered funds to be assets in whatever form, including digital currencies. Article 3 of Law No. 8 of 2017 on value-added tax imposes a 5% tax on imported and exported commodities. This tax may apply to utility tokens and non-fiat cryptocurrencies, as the FSRA considers them to be commodities.

The UAE does not have a signed tax treaty agreement with the United States. However, according to the Conduct of Business Rulebook, crypto-asset businesses are obligated to declare international income for tax purposes according to the requirements of the intergovernmental Foreign Account Tax Compliance Act agreement between the UAE and the United States.

Conclusion

A green recovery is an absolute imperative for a sustainable social and economic future in the post-pandemic world, as pointed out by Alok Sharma, president of the 26th United Nations Climate Change Conference of the Parties — better known as COP26 — who praised Masdar’s undertakings in developing green energy technologies.

Finding financing for this green transition will likely not be too challenging, according to Khaldoon Khalifa Al Mubarak, managing director and group CEO of Mubadala Investment Corporation. Because a tectonic paradigm shift has occurred since the COVID-19 pandemic, with the markets pricing climate risk into the value of securities, there is a fundamental reallocation of capital toward sustainable investing to ensure a green recovery in a post-COVID-19 world. As Laurence Fink, chairman and CEO of BlackRock — the world’s largest asset manager — pointed out:

“I believe that the pandemic has presented such an existential crisis — such a stark reminder of our fragility — that it has driven us to confront the global threat of climate change more forcefully and to consider how, like the pandemic, it will alter our lives. It has reminded us how the biggest crises, whether medical or environmental, demand a global and ambitious response.”
