Distributed Ledger Technology: The Blockchain Minitrack
Blockchain 3.0, the Encryption of Innovation. This talk looks beyond the immediate economic benefits and risks of distributed ledgers and considers the broader societal innovations implied by blockchain technology. The possibility of innovation and creating and participating in different and multiple self-determined political and economic systems could mobilize how we create ourselves as individuals and societies. Blockchain technology invites the possibility of creating a social world that gives greater weight to the values we apparently care about: freedom, trust, and dignity

There is no "right or wrong" answer here; however, it is imperative that you substantiate your commentary. For this assignment, you are to answer the following questions with a minimum of 200 words.
1.In some states, such as in Colorado, state governments have legalized the possession and use of marijuana for its citizens. However, a federal law, known as The Controlled Substances Act of 1970, makes the possession and use of marijuana illegal under federal law.
If Article VI of the United States Constitution stipulates that federal law takes precedence over state laws (known as the Supremacy Clause), then how is it that some states can make marijuana legal?
The question posed to you this week is as follows:
1. Are states that legalize marijuana in violation of the Supremacy Clause contained in Article VI of the United States Constitution? Why or why not
2.Currently, in the private sector, according to the Bureau of Labor Statistics, a woman typically makes 87 percent of the wage a man makes in a similar position with similar responsibilities. There are some who state that women are more expensive to employ, primarily due to women being the bearer of children and the extended time off typically required after the birth of a child. However, there are others who state that this constitutes a violation of the Equal Protection Clause of the 14th Amendment, that women should be paid the same as men with similar positions and similar responsibilities. Even with the Equal Pay Act of 1963, signed into law by then-President John Kennedy, we still see these disparities in pay between the genders. Hence, the question I have for you is:
2.What steps can we take to ensure equal pay between genders for employment positions with similar responsibilities and similar duties?

Abstract
Blockchain is a decentralized transaction and data management technology developed first
for Bitcoin cryptocurrency. The interest in Blockchain technology has been increasing since
the idea was coined in 2008. The reason for the interest in Blockchain is its central attri-
butes that provide security, anonymity and data integrity without any third party organiza-
tion in control of the transactions, and therefore it creates interesting research areas,
especially from the perspective of technical challenges and limitations. In this research, we
have conducted a systematic mapping study with the goal of collecting all relevant research
on Blockchain techno ...

ABC chocolate manufacturing company needs to decide on how many chocolate bars should they produce each month to maximize the company profit. ABC consider two types of chocolate bar ‘dark' and 'salted caramel’. Dark chocolate bar required $20 of raw ingredients and take 2 day to make and salted caramel chocolate bar required $30 of raw ingredients and take 4 working days to make. The profit contribution of each dark chocolate bar is $2 and salted caramel chocolate bar is $5. The Manufacture has capacity of 100,000 working days per month and ingredients budget of $10,000 per month. Using linear programming modelling for ABC company problem, answer the following questions.

ADPP: A NOVEL ANOMALY DETECTION AND PRIVACY-PRESERVING FRAMEWORK USING BLOCKC...ijaia
The increasing popularity of crypto assets has resulted in greater cryptocurrency investor interest and more exposure in both industry and academia. Despite the substantial socioeconomic benefits, the anonymous character of cryptocurrency trading makes it prone to abuse and a magnet for illicit purposes, which cause monetary losses for individual traders and erosion in the standing of the tokenomics industry. To regulate the illicit behavior and secure users' privacy for cryptocurrency trading, we present an Anomaly Detection and Privacy-Preserving (ADPP) Framework integrating blockchain and deep learning technologies. Specifically, ADPP leverages blockchain technologies to build a user management platform that ensures anonymity and enhances the privacy-preservation of user information. Atop the user management system, an Anomaly Detection System adapts neural networks and imbalanced learning on topological cryptocurrency flow among users to identify anomalous addresses and maintain a sanction list repository. The experiments on the real-world dataset demonstrate the effectiveness and superior performance of ADPP. The flexible framework can be easily generalized to the crypto assets with public real-time transaction (e.g., Non-fungible Token), which takes up a significant proportion of market capitalization in the domain of tokenomics.

Blockchain is a decentralized, digital, and consensus-based secure information storage system. This article gives an overview of how to use the blockchain to construct a secure and trustworthy electronic voting system. The main goal of this paper is to investigate the most recent state of blockchain-based voting research while attempting to foresee the accompanying potential issues future developments. This paper's technique is as follows: a methodical approach to review and following an overview of the blockchain's core structure and properties in relation. We present a conceptual definition of e-voting. Desired e-voting application based on blockchain symmetrical improvements in asymmetrical cryptography are also important. We gathered and examined a number of research papers from scientific databases that advocated for the use of the blockchain architecture in voting systems. These articles suggested that blockchain-based voting systems may offer alternatives to standard e-voting. The most pressing challenges were divided into five categories: general, integrity, coin-based, privacy, and consensus. As a consequence of this study, it was discovered that blockchain systems can help solve some of the issues that now plague election systems. We are attempting to design a system that respects the essential and most significant aspects of a voting system, such as transparency, secrecy, security, and decentralisation, while also providing the extra benefit of mobility.

A blockchain is a distributed database on a peer-to-peer network. It is the underlying technology of the bitcoin cryptocurrency. Secure transactions between users are possible without the need for a central server or trusted authority. Blockchain technology can be used for other cases than money transfer, such as exchange of other assets, votes or credits and for provenance or identity management. Recently, discussions started whether this technology could be useful for (life) sciences. The blockchain technology will be explained and its potential and weaknesses.

This paper aims to give a primary overview of how cryptocurrencies are created by using the proof of work method and how blockchain works. Statistical references have been given to elaborate on how this process consumes high energy and increases carbon footprint causing harm to the environment. In comparison, the proof of stake method has established itself as an eco-friendly alternative. Ethereum has already manifested that using PoS can resolve the problem and is also safe for the environment.

when will pi network coin be available on crypto exchange.DOT TECH
There is no set date for when Pi coins will enter the market.
However, the developers are working hard to get them released as soon as possible.
Once they are available, users will be able to exchange other cryptocurrencies for Pi coins on designated exchanges.
But for now the only way to sell your pi coins is through verified pi vendor.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.

how can I sell pi coins after successfully completing KYCDOT TECH
Pi coins is not launched yet in any exchange 💱 this means it's not swappable, the current pi displaying on coin market cap is the iou version of pi. And you can learn all about that on my previous post.
RIGHT NOW THE ONLY WAY you can sell pi coins is through verified pi merchants. A pi merchant is someone who buys pi coins and resell them to exchanges and crypto whales. Looking forward to hold massive quantities of pi coins before the mainnet launch.
This is because pi network is not doing any pre-sale or ico offerings, the only way to get my coins is from buying from miners. So a merchant facilitates the transactions between the miners and these exchanges holding pi.

what is the future of Pi Network currency.DOT TECH
The future of the Pi cryptocurrency is uncertain, and its success will depend on several factors. Pi is a relatively new cryptocurrency that aims to be user-friendly and accessible to a wide audience. Here are a few key considerations for its future:
Message: @Pi_vendor_247 on telegram if u want to sell PI COINS.
1. Mainnet Launch: As of my last knowledge update in January 2022, Pi was still in the testnet phase. Its success will depend on a successful transition to a mainnet, where actual transactions can take place.
2. User Adoption: Pi's success will be closely tied to user adoption. The more users who join the network and actively participate, the stronger the ecosystem can become.
3. Utility and Use Cases: For a cryptocurrency to thrive, it must offer utility and practical use cases. The Pi team has talked about various applications, including peer-to-peer transactions, smart contracts, and more. The development and implementation of these features will be essential.
4. Regulatory Environment: The regulatory environment for cryptocurrencies is evolving globally. How Pi navigates and complies with regulations in various jurisdictions will significantly impact its future.
5. Technology Development: The Pi network must continue to develop and improve its technology, security, and scalability to compete with established cryptocurrencies.
6. Community Engagement: The Pi community plays a critical role in its future. Engaged users can help build trust and grow the network.
7. Monetization and Sustainability: The Pi team's monetization strategy, such as fees, partnerships, or other revenue sources, will affect its long-term sustainability.
It's essential to approach Pi or any new cryptocurrency with caution and conduct due diligence. Cryptocurrency investments involve risks, and potential rewards can be uncertain. The success and future of Pi will depend on the collective efforts of its team, community, and the broader cryptocurrency market dynamics. It's advisable to stay updated on Pi's development and follow any updates from the official Pi Network website or announcements from the team.

Financial Assets: Debit vs Equity Securities.pptxWrito-Finance
financial assets represent claim for future benefit or cash. Financial assets are formed by establishing contracts between participants. These financial assets are used for collection of huge amounts of money for business purposes.
Two major Types: Debt Securities and Equity Securities.
Debt Securities are Also known as fixed-income securities or instruments. The type of assets is formed by establishing contracts between investor and issuer of the asset.
• The first type of Debit securities is BONDS. Bonds are issued by corporations and government (both local and national government).
• The second important type of Debit security is NOTES. Apart from similarities associated with notes and bonds, notes have shorter term maturity.
• The 3rd important type of Debit security is TRESURY BILLS. These securities have short-term ranging from three months, six months, and one year. Issuer of such securities are governments.
• Above discussed debit securities are mostly issued by governments and corporations. CERTIFICATE OF DEPOSITS CDs are issued by Banks and Financial Institutions. Risk factor associated with CDs gets reduced when issued by reputable institutions or Banks.
Following are the risk attached with debt securities: Credit risk, interest rate risk and currency risk
There are no fixed maturity dates in such securities, and asset’s value is determined by company’s performance. There are two major types of equity securities: common stock and preferred stock.
Common Stock: These are simple equity securities and bear no complexities which the preferred stock bears. Holders of such securities or instrument have the voting rights when it comes to select the company’s board of director or the business decisions to be made.
Preferred Stock: Preferred stocks are sometime referred to as hybrid securities, because it contains elements of both debit security and equity security. Preferred stock confers ownership rights to security holder that is why it is equity instrument
<a href="https://www.writofinance.com/equity-securities-features-types-risk/" >Equity securities </a> as a whole is used for capital funding for companies. Companies have multiple expenses to cover. Potential growth of company is required in competitive market. So, these securities are used for capital generation, and then uses it for company’s growth.
Concluding remarks
Both are employed in business. Businesses are often established through debit securities, then what is the need for equity securities. Companies have to cover multiple expenses and expansion of business. They can also use equity instruments for repayment of debits. So, there are multiple uses for securities. As an investor, you need tools for analysis. Investment decisions are made by carefully analyzing the market. For better analysis of the stock market, investors often employ financial analysis of companies.
US Economic Outlook - Being Decided - M Capital Group August 2021.pdfpchutichetpong
The U.S. economy is continuing its impressive recovery from the COVID-19 pandemic and not slowing down despite re-occurring bumps. The U.S. savings rate reached its highest ever recorded level at 34% in April 2020 and Americans seem ready to spend. The sectors that had been hurt the most by the pandemic specifically reduced consumer spending, like retail, leisure, hospitality, and travel, are now experiencing massive growth in revenue and job openings.
Could this growth lead to a “Roaring Twenties”? As quickly as the U.S. economy contracted, experiencing a 9.1% drop in economic output relative to the business cycle in Q2 2020, the largest in recorded history, it has rebounded beyond expectations. This surprising growth seems to be fueled by the U.S. government’s aggressive fiscal and monetary policies, and an increase in consumer spending as mobility restrictions are lifted. Unemployment rates between June 2020 and June 2021 decreased by 5.2%, while the demand for labor is increasing, coupled with increasing wages to incentivize Americans to rejoin the labor force. Schools and businesses are expected to fully reopen soon. In parallel, vaccination rates across the country and the world continue to rise, with full vaccination rates of 50% and 14.8% respectively.
However, it is not completely smooth sailing from here. According to M Capital Group, the main risks that threaten the continued growth of the U.S. economy are inflation, unsettled trade relations, and another wave of Covid-19 mutations that could shut down the world again. Have we learned from the past year of COVID-19 and adapted our economy accordingly?
“In order for the U.S. economy to continue growing, whether there is another wave or not, the U.S. needs to focus on diversifying supply chains, supporting business investment, and maintaining consumer spending,” says Grace Feeley, a research analyst at M Capital Group.
While the economic indicators are positive, the risks are coming closer to manifesting and threatening such growth. The new variants spreading throughout the world, Delta, Lambda, and Gamma, are vaccine-resistant and muddy the predictions made about the economy and health of the country. These variants bring back the feeling of uncertainty that has wreaked havoc not only on the stock market but the mindset of people around the world. MCG provides unique insight on how to mitigate these risks to possibly ensure a bright economic future.
