Introduction to Blockchain and CryptocurrenciesNikhil D Prince
This document provides an introduction to blockchain and cryptocurrencies. It discusses the history of blockchain from 1991 when it was first described to 2009 when Bitcoin launched. It defines blockchain as an immutable time-stamped series of records distributed and managed by a peer-to-peer network. It also discusses the differences between centralized, decentralized, and distributed networks. The document outlines different types of blockchains and applications of blockchain like payments, supply chain monitoring, and medical recordkeeping. It notes both benefits like cost effectiveness and reduced reliance on trusted parties, as well as challenges like energy consumption and inability to change past data.
The major advantage of blockchain data structure is that it automates auditing and makes an application transparent yet secure. It can prevent fraud and corruption. It can be used to solve many other problems depending on how you implement and use it.

Blockchain is a method for storing information that makes it difficult or impossible to change, hack, or cheat the system. It involves a network of computers called nodes that maintain an identical history of transactions. Whenever a transaction occurs, it is validated by all nodes and added to the transaction history if approved. Blockchain technology is not only used for Bitcoin but Bitcoin uses it to function as a digital currency. Key components of a blockchain include hashes, the mempool of pending transactions, merkle roots to validate transactions efficiently, nonces as random numbers, and proof of work puzzles to validate transactions.

There are 7 main stages for making whiskey from barley: 1) malting, 2) kilning, 3) milling, 4) mashing, 5) fermenting, 6) distilling, and 7) aging. Vodka can be made from grains or potatoes through a process involving mash preparation, fermentation, multiple distillations, water addition, and bottling. The key differences are that whiskey is aged in wood barrels whereas vodka is not aged.
The document discusses the concept of "hooks" which are experiences designed to form habits by connecting a solution to a user's problem through triggers, actions, variable rewards, and investments. Triggers initiate the behavior and can be external cues or internal emotions/states. Actions are the simplest behaviors users can do to receive a reward. Rewards need to be variable and fulfill needs for resources, social acceptance, or mastery while maintaining user autonomy. Investments require small efforts from users to increase the likelihood they will engage in the next trigger-action-reward loop and form a habit. Together these elements can be used to design habit-forming technology and increase user engagement.

Cryptocurrencies have technological differences in their blockchains, consensus algorithms, and features. Blockchains solve the double spending problem by only allowing one valid transaction when multiple are presented. Bitcoin has faced issues with decentralization due to mining pools and scalability due to its 1MB block size limit. Newer cryptocurrencies implement different consensus algorithms like proof-of-stake to reduce energy use compared to Bitcoin's proof-of-work. Decentralized exchanges allow trading of cryptocurrencies without centralized control through techniques like multisignature transactions. Future cryptocurrencies may achieve better scalability, anonymity, and decentralization through approaches like directed acyclic graphs and masternode-based networks.

Blockchain technology was introduced in 2008 with the Bitcoin whitepaper. It allows digital transactions to be recorded in a distributed public ledger without a central authority. Key aspects include no reliance on trust, digital signatures, a peer-to-peer network, proof-of-work, and consensus. Bitcoin uses blockchain to keep track of transactions through mining, where nodes validate transactions and are rewarded with new bitcoins. Blockchain has applications beyond digital currency, including storing digital records, exchanging digital assets like tokens, and executing smart contracts.

Optimizing Net Interest Margin (NIM) in the Financial Sector (With Examples).pdfshruti1menon2
NIM is calculated as the difference between interest income earned and interest expenses paid, divided by interest-earning assets.
Importance: NIM serves as a critical measure of a financial institution's profitability and operational efficiency. It reflects how effectively the institution is utilizing its interest-earning assets to generate income while managing interest costs.
Every business, big or small, deals with outgoing payments. Whether it’s to suppliers for inventory, to employees for salaries, or to vendors for services rendered, keeping track of these expenses is crucial. This is where payment vouchers come in – the unsung heroes of the accounting world.
In a tight labour market, job-seekers gain bargaining power and leverage it into greater job quality—at least, that’s the conventional wisdom.
Michael, LMIC Economist, presented findings that reveal a weakened relationship between labour market tightness and job quality indicators following the pandemic. Labour market tightness coincided with growth in real wages for only a portion of workers: those in low-wage jobs requiring little education. Several factors—including labour market composition, worker and employer behaviour, and labour market practices—have contributed to the absence of worker benefits. These will be investigated further in future work.
"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.

OJP data from firms like Vicinity Jobs have emerged as a complement to traditional sources of labour demand data, such as the Job Vacancy and Wages Survey (JVWS). Ibrahim Abuallail, PhD Candidate, University of Ottawa, presented research relating to bias in OJPs and a proposed approach to effectively adjust OJP data to complement existing official data (such as from the JVWS) and improve the measurement of labour demand.
4. Bitcoin dev = stalled
I’ve been very worried for a long time
that the core bitcoin system is radically
underfunded and underdeveloped from
where it needs to be.
development of the bitcoin
protocol has ground to a
“complete halt”
No new Protocol Features expected
5. The Master Protocol
• A financial layer that uses Bitcoin
• Inherits all of Bitcoin’s benefits
• Adds Security, Exchange, and Issuing
• Is not “yet another altcoin”
7. Protocol Structure
• Every Master Protocol transaction is a Bitcoin tx
• Original Class A (increasing UTXO)
• Class B = Multisig
• Class C = OP_RETURN
• Future = github.com/petertodd/blockpop
18. • Burning MSC:
Monetization
– Decentralized Exchange
– Pay to Owners
– Other advanced operations
– Voting determines the fee
• MSC as a based liquidity layer for the DEx
