The metaverse is money and crypto is king: Why you'll be on a blockchain when virtual-world hopping

You may think the metaverse will be a bunch of interconnected virtual spaces—the world wide web but accessed through virtual reality. This is largely correct, but there is also a fundamental but slightly more cryptic side to the metaverse that will set it apart from today's internet: the blockchain.

In the beginning, Web 1.0 was the information superhighway of connected computers and servers that you could search, explore and inhabit, usually through a centralized company's platform—for example, AOL, Yahoo, Microsoft and Google. Around the turn of the millennium, Web 2.0 came to be characterized by , blogging and the monetization of user data for advertising by the centralized gatekeepers to "free" social media platforms, including Facebook, SnapChat, Twitter and TikTok.

Web 3.0 will be the foundation for the . It will consist of -enabled decentralized applications that support an economy of user-owned crypto assets and data.

Blockchain? Decentralized? Crypto-assets? As researchers who study social media and media technology, we can explain the technology that will make the metaverse possible.

Owning bits

Blockchain is a technology that permanently records transactions, typically in a decentralized and public database called a ledger. Bitcoin is the most well-known blockchain-based cryptocurrency. Every time you buy some bitcoin, for example, that transaction gets recorded to the Bitcoin blockchain, which means the record is distributed to thousands of individual computers around the world.

This decentralized recording system is very difficult to fool or control. Public blockchains, like Bitcoin and Ethereum, are also transparent—all transactions are available for anyone on the internet to see, in contrast to traditional banking books.

Ethereum is a blockchain like Bitcoin, but Ethereum is also programmable through smart contracts, which are essentially blockchain-based software routines that run automatically when some condition is met. For example, you could use a smart contract on the blockchain to establish your ownership of a digital object, such as a piece of art or music, to which no one else can claim ownership on the blockchain—even if they save a copy to their computer. Digital objects that can be owned—currencies, securities, artwork—are crypto assets.

Items like artwork and music on a blockchain are nonfungible tokens (NFTs). Nonfungible means they are unique and not replaceable, the opposite of fungible items like currency—any dollar is worth the same as, and can be swapped with, any other dollar.

Importantly, you could use a smart contract that says you are willing to sell your piece of digital art for US$1 million in ether, the currency of the Ethereum blockchain. When I click "agree," the artwork and the ether automatically transfer ownership between us on the blockchain. There is no need for a bank or third-party escrow, and if either of us were to dispute this transaction—for example, if you claimed that I only paid $999,000—the other could easily point to the public record in the distributed ledger.

What does this blockchain crypto-asset stuff have to do with the metaverse? Everything! To start, the blockchain allows you to own digital goods in a virtual world. You won't just own that NFT in the , you'll own it in the virtual world, too.

In addition, the metaverse isn't being built by any one group or company. Different groups will build different virtual worlds, and in the future these worlds will be interoperable—forming the metaverse. As people move between virtual worlds—say from Decentraland's virtual environments to Microsoft's—they'll want to bring their stuff with them. If two virtual worlds are interoperable, the blockchain will authenticate proof of ownership of your digital goods in both virtual worlds. Essentially, as long as you are able to access your crypto wallet within a virtual world, you will be able to access your crypto stuff.

The metaverse doesn’t exist yet, but that hasn’t stopped a land rush as people and businesses grab virtual real estate.

Don't forget your wallet

So what will you keep in your crypto ? You will obviously want to carry cryptocurrencies in the metaverse. Your crypto wallet will also hold your metaverse-only digital goods, such as your avatars, avatar clothing, avatar animations, virtual decorations and weapons.

What will people do with their crypto wallets? Among other things, shop. Just as you likely do on the web now, you will be able to purchase traditional digital goods like music, movies, games and apps. You'll also be able to buy physical-world items in the metaverse, and you'll be able to view and "hold" 3D models of what you are shopping for, which could help you make more informed decisions.

Also, just like you can use ye old leather wallet to carry your ID, crypto wallets will be linkable to real-world identities, which could help facilitate transactions that require legal verification, such as buying a real-world car or home. Because your ID will be linked to your wallet, you won't need to remember login information for all the websites and virtual worlds that you visit—just connect your wallet with a click and you are logged in. ID-associated wallets will also be useful for controlling access to age-restricted areas in the metaverse.

Your crypto wallet could also be linked to your contacts list, which would allow you to bring your social network information from one  to another. "Join me for a pool party in FILL IN THE BLANK-world!"

At some point in the future, wallets could also be associated with reputation scores that determine the permissions you have to broadcast in public places and interact with people outside of your social network. If you act like a toxic misinformation-spreading troll, you may damage your reputation and potentially have your sphere of influence reduced by the system. This could create an incentive for people to behave well in the metaverse, but platform developers will have to prioritize these systems.

Big business

Lastly, if the metaverse is money, then companies will certainly want to play too. The decentralized nature of blockchain will potentially reduce the need for gatekeepers in financial transactions, but companies will still have many opportunities to generate revenue, possibly even more than in current economies. Companies like Meta will provide large platforms where people will workplay and congregate.

Major brands are also getting into the NFT mix, including Dolce & GabbanaCoca-ColaAdidas and Nike. In the future, when you buy a physical world item from a company, you might also gain ownership of a linked NFT in the metaverse.

For example, when you buy that coveted name-brand outfit to wear to the real-world dance club, you might also become the owner of the crypto version of the outfit that your avatar can wear to the virtual Ariana Grande concert. And just as you could sell the physical outfit secondhand, you could also sell the NFT version for someone else's avatar to wear.

These are a few of the many ways that metaverse business models will likely overlap with the physical world. Such examples will get more complex as augmented reality technologies increasingly come into play, further merging aspects of the metaverse and physical world. Although the metaverse proper isn't here yet, technological foundations like blockchain and crypto assets are steadily being developed, setting the stage for a seemingly ubiquitous virtual future that is coming soon to a 'verse near you.

CANADA

Report indicates moving rapidly from financial stress to financial comfort may be possible

If a new report from the Financial Wellness Lab of Canada at Western University is any indication, moving from a financially stressed situation to a more comfortable level in a relatively short period of time may not be an impossible feat.

While financial stress might feel inescapable, the report, "Financial Wellness Lab—State of the Nation—December 2021," has found that 16.1 percent of Canadians whom the research determined were financially stressed in 2020 were able to move into the financially comfortable category in one year. While this is not an indication that moving from financially stressed to being financially comfortable is easy or obstacle-free, the report does provide some hope for those who might be feeling despair.

The report is an early output from the Lab, which aims to develop a science-based, big-picture understanding of financial wellness and deliver information and tools to help Canadians improve or maintain their financial fitness.

"Up until now, our understanding of financial wellness has looked at specific aspects of the topics," said Matt Davison, dean of science at Western. "At the Financial Wellness Lab of Canada, we are combining leading analytics tools and methodology, a multi-disciplinary approach and deep data sets furnished by industry partners to draw connections between research that have already deen done, and articulate a road map towards financial wellness. This includes identification of factors that can either slow or accelerate one's journey."

Spectrum of financial wellness

While it can be complex to determine a household's financial positioning, the report confirms that Canadians generally fall into three categories of financial well-being: financially comfortable, financially coping and financially stressed.

"Where one falls on this spectrum depends on a variety of factors, but savings habits, spending and debt seem to be especially predictive," said Adam Metzler, associate professor at Laurier University, a partner institution in the Financial Wellness Lab.

While each cluster is distinct, the comfortable and coping clusters seem to be 'closer together,' meaning they share more common traits. As a result, movement between these clusters is more frequent relative to moving out of the stressed group. Interestingly, the research has indicated that while making more  can help, it does not necessarily correlate to improved financial wellness.

"Because savings, spending and debt are so interconnected, it may be impossible for us to fully understand financial wellness by studying them in isolation," adds Metzler. "Improving these habits, and moving to a more 'comfortable' cluster, is far from simple. They are impacted by personal circumstances and external factors that are seemingly out of our control, like the cost of housing which is an area that we should all be concerned about."

Home ownership factor

As one of Canadians' most significant expenses, the cost of housing can have a disproportionate impact on financial wellness. This is especially true in light of the current real-estate boom and the low-interest rates, of which so many have taken advantage, and the ability to work remotely to purchase a new home.

While home ownership does not distinguish the clusters from one another, there are significant differences in the percentage of monthly income spent on housing costs. Fifty-eight percent of the comfortable group spend less than 30 percent of their monthly income on housing costs, while 66 percent of the stressed cluster spend more than 40 percent. The Canada Mortgage and Housing Corporation (CMHC) have set 39 percent of monthly income allocated to housing as the threshold for mortgage approval.

Recent data analyzed by the Lab also shows that housing affordability and its associated debt is of paramount concern for Canadian households. Even within the comfortable category, 29 percent are concerned about their debt load, and 23 percent are spending more on housing than CMHC's recommended threshold.

From these data points, it appears that housing costs are straining the finances of far too many. And, given that most housing purchases are made possible by taking on debt, an interest rate increase has the potential to add significant financial hardship for those who were only able to purchase their home because rates were low.

Path to financial wellness

Despite the obstacles ahead, it is possible for Canadians to make a plan and chart a course toward improving their financial wellness. It requires knowing where you are—a determination that is not always easy because of certain complexities.

"We're often told that the answer to financial wellness is to spend less and save more," said Davison, "But that seemingly simple advice can be challenging for people to put into action without specific and personalized guidance. Where the Lab can help is to show Canadians specific tools that can help them make better decisions and take small, meaningful steps towards financial resilience, backed by real, objective data."

In partnership with the Lab, the Canadian Payroll Association has developed a new Financial Fitness Evaluator to help Canadians determine their financial wellness. After receiving their analysis, respondents are provided with tools and resources to help make meaningful changes to their financial habits. The results are anonymous, and the tool is free to use.Student loans linked to greater harm for parents who borrow for their children than people who borrow for themselves

UK government: 4°C warming by 2100

 "can't be ruled out"

As required by the Climate Change Act 2008, the government has today submitted the Third UK Climate Change Risk Assessment (CCRA3) to Parliament.

The CCRA3 is partly based on an independent Technical Report by a large team of experts led by the University of Exeter, in partnership with the Met Office.

Professor Richard Betts MBE, who led this team, says that ""ne of the key conclusions from the University of Exeter's work was that current worldwide policies could result in up to 4°C warming by 2100."

"The agreements made at the COP26 climate summit in November have reduced the likelihood of this, but it remains possible."

The Technical Report concluded that global warming is already bringing substantial risks to the UK's natural environment, infrastructure, human health, communities and businesses.

It also concluded that the UK is subject to international risks relating to issues such as security, migration and supply chains.

All these risks are expected to be higher at global warming of 2°C, and would be even greater if warming were to reach 4°C.

Professor Betts continued that "COP26 fell short of its aims, and it is becoming less likely that we will be able limit global warming to low levels. The Paris Agreement's 1.5°C goal is slipping out of reach."

"We need to be better prepared for the climate changes we have already caused."

Professor Betts, of the University of Exeter and the Met Office, welcomed the publication of the CCRA3.

"We are glad to see our science included in this key report, which does not shy away from the high levels of warming that could occur," he added.

The Technical Report, the findings of which were presented by Professor Betts at COP26 in Glasgow, involved more than two years of work, drawing on numerous scientific papers and other reports as well as new research.

It also involved extensive engagement with a large number of stakeholders in government, the private sector and civil society organizations with responsibility for adapting to climate change or expertise in how this can take place. 

The CCRA3  published today also relied on independent advice from the Climate Change Committee (CCC) on the risks posed to the UK from climate change, and the extent to which the UK is unprepared.

Baroness Brown of Cambridge, chair of the CCC's Adaptation Committee, says that "expert input to CCRA3 process was vital to ensure that the assessment is based on sound evidence."

"The team led by the University of Exeter produced a robust, authoritative Technical Report which provided a solid foundation for the CCC's advice to government, and provides crucial information for the UK to act on under the National Adaption Programme."

Professor Lisa Roberts, Vice-Chancellor of the University of Exeter, said that "we are proud to have played a leading role in this vital piece of climate change work."

"This was achieved by working together with the Met Office, the CCC and other universities and organizations, to bring together the required expertise and viewpoints from a wide range of disciplines."

"Adapting and responding to life-changing climate change is the biggest challenge of our generation and that is why the University of Exeter has brought together the strength and power of more than 600 of our researchers working on the climate and ecological crisis at the heart of our 2030 strategy."

"We are committed to working in partnership with governments, businesses and communities in the critical decade ahead."

Experts from many institutions, including Exeter, are already working on research that will underpin the next CCRA.

Antimicrobial resistance is a leading cause of death globally

In 2019, 1.27 million deaths were due to treatment-resistant infections



Escherichia coli, Klebsiella pneumoniae (shown here in a culture dish) and Staphylococcus aureus were the top three among the bacteria responsible for fatal drug-resistant infections worldwide in 2019.

By Aimee Cunningham

Bacterial infections that don’t respond to treatment are a leading cause of death around the world.


In 2019, antimicrobial resistance caused an estimated 1.27 million deaths, researchers report January 19 in the Lancet. More people died from untreatable bacterial infections that year than from HIV or malaria.

Overall, bacterial antimicrobial resistance played a role in an estimated 4.95 million deaths globally, including the 1.27 million directly caused by resistant infections, the study found. The estimates are based on an analysis of hospital, surveillance and other sources of data covering 204 countries and territories by an international group of researchers called the Antimicrobial Resistance Collaborators.

Resistance to two classes of antibiotics, beta-lactams (which include penicillin) and fluoroquinolones, was behind more than 70 percent of resistance-caused deaths. Those drugs are the first-line options for many bacterial infections (SN: 4/30/14).


Among the bacteria responsible for fatal drug-resistant infections, the top three were Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus, the researchers found. These pathogens can cause dangerous infections in health care settings in people with weakened immune systems.

Worldwide, 64 deaths per 100,000 people were associated with treatment-resistant bacterial infections and 16.4 deaths per 100,000 people were caused by such infections, the group found. Notably, western sub-Saharan Africa had the highest mortality rates: 114.8 deaths per 100,000 people were associated with bacterial antimicrobial resistance and 27.3 deaths per 100,000 people were due to resistance.

Overall, the mortality rate from bacterial antimicrobial resistance was higher in places with fewer health care resources. This illustrates that solutions need to consider regional differences, the research group says. Limits on antibiotic use to deter resistance is key in many places. But in western sub-Saharan Africa, for example, increasing access to antibiotics may lessen the mortality burden from resistance, since second-line antibiotics needed after first-line drugs fail aren’t readily available.

Urban Violence in Fifth Century Antioch: Riot Culture and Dynamics in Late Antique Eastern Mediterranean Cities

David A. Heayn

History

In the early fourth century, during the reign of the first Christian emperor, Constantine the Great (AD 324-337), Antioch was one of the largest and most important political, cultural, and religious centers of the Greco-Roman and Christian world

 Christians, Jews, Pagans, Greeks, Syrians, et al, vied for control within the city. This form of internal urban violence and armed revolt were common in the Greek East. Antioch was a city attempting to transition from a Greco-Roman Pagan society to an orthodox Christian society in a recently Christian empire.

 The Persian invasion and a deficiency of source material hinder further historical inquiry of this period until the later writings of John Chrysostom and Libanius in the mid-fourth century. Until the natural disasters of the early sixth century AD and the subsequent Persian and Arab invasions, Antioch flourished as the jewel of the East, and its people fought for domination and control of its wealth, power, and authority.

 During the fifth century, riots erupted in the city due to the transition towards becoming a truly Christian empire. Questions surrounding Christian doctrine and authority across the empire and region fueled the rhetoric, while economics and politics fed the violence.

The unresolved difficulty of Acts 18.12–17 involves finding an adequate explanation for the (seemingly) unprovoked hostile reaction of the crowd toward Sosthenes, the ruler of the synagogue in Corinth. This investigation places this incident within the larger social context of urban uprisings and mob violence in the Roman world in order to highlight the socioeconomic factors (poverty, overcrowding, etc.) that inevitably gave rise to such frequent outbursts of urban aggression during this period. As such, this study illumines not only Acts 18, but other passages in Acts where mob violence plays a leading role. Whenever a blast of turbulence falls upon the assembly. .. we find jibes and brawling and laughter. Dio Chrysostom Luke's brief account of the mobbing of Sosthenes in Acts 18.12–17 presents historians and exegetes with a fascinating set of questions, not least of which is accounting for the sudden rush of the crowd on Sosthenes, the unsuspecting and unprepared ruler of the synagogue in Corinth. Surprisingly, this issue receives scant discussion in commentaries and secondary literature, with most appealing without argument to an anti-Jewish bias on the part of the assembly and the pro-consul Gallio, who turned a blind eye to the disturbance. 1 While xenophobic 1 E.g.

Popular Justice and Street Theatre in Late Roman Cities

882 ViewsPaperRank: 2.311 Pages
The rituals of popular justice that characterized the urban life of the Roman Empire in the fourth and fifth centuries are also one of the most obvious links we can establish between popular culture and the urban space. Forms of collective sanction, such as the public humiliation and the menacing parade, the destruction of properties, and the lynching of offenders, were all public performances that took place in the streets and squares of cities. Such performances also depended on customary practices of occupation of the urban space and shared some features with the festive rituals that paced the urban life. For all these reasons, in its conception and in its enactment, popular justice can properly be viewed as a kind of “street theatre”. Historians of other periods had for long explored such links between riot and carnival and the ways customary forms of popular justice could be adapted to different social contexts. But as Nicholas Rogers has rightly stressed, an obsession with symbolism and ritual can easily lead to a “cosmic populism”, that is, to the exaltation of irreverent counter-cultures, to the detriment of analyses of power. In this essay, I would like to identify some of the main characteristics of popular justice and street theatre in Late Antiquity, paying special attention to their rituals, mechanisms and processes. But in order to understand the historical significance of these practices, we must also to replace them in the broader political context of the Late Roman cities, at a time of increasing mobilization of the common people in the struggles for power in the urban space.
