Curious case of bitcoins
Bitcoin is a decentralized digital currency that allows for instant peer-to-peer transactions without banks or fees. It is mined by users who verify transactions and maintain the blockchain ledger through a distributed consensus system. While it offers advantages like worldwide payments and uncensorable accounts, it has also been used on dark markets for illegal goods until the shutdown of Silk Road in 2013.
Crypto currency1
This document discusses cryptocurrency and provides an overview of Bitcoin. It defines cryptocurrency as a digital currency secured through cryptography that allows for peer-to-peer transactions without an intermediary. The document outlines the risks of cryptocurrency including hackers, lack of protections, costs, and scams. It also describes how Bitcoin works, including how the blockchain records transactions in blocks to form a public ledger. Mining is explained as the process of adding new transaction records to the blockchain by solving complex math problems.
Blockchain seminar
Blockchain technology was first conceptualized in 1991 but did not have a real-world application until Bitcoin was launched in 2009. A blockchain is a distributed ledger of transactions stored in blocks that are linked together via cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Nodes on the network run by participants hold copies of the blockchain and work to validate transactions and add them to new blocks through a process called mining. This process secures the network and allows participants to reach a consensus without the need for a centralized authority. Today, blockchain technology has applications across many industries that require trustless transactions.
Bitcoin basics
Bitcoin is a decentralized digital currency that allows for fast transfer of value through the internet without middlemen. It works through a peer-to-peer network that confirms transactions and records them on a public blockchain. Users can obtain bitcoins by accepting them as payment, buying them on exchanges, or participating in bitcoin mining by solving computational puzzles to validate transactions and earn new bitcoins as a reward. There is a finite supply of 21 million bitcoins that will be created by approximately the year 2040.
Bitcoin Lightning Network - Presentation
The Lightning Network is a solution to Bitcoin's scalability problem that allows for high volumes of fast and cheap transactions to be conducted off the blockchain. It creates payment channels that enable direct and instant transfers between two parties without waiting for transaction confirmations. This helps Bitcoin fulfill its potential as a global, decentralized payment system and scales far beyond the current 7 transactions per second that can be supported on-chain.
190603 Value of Bitcoin Conference
This session will explore the initial design considerations behind Bitcoin, the first private money existing exclusively in the digital realm. Key properties such as artificial scarcity, unseizability, and censorship-resistant value transfer will be discussed, with a focus on how these characteristics are achieved. An argument will be brought forward that Bitcoin (and similar cryptocurrency systems) need to be inefficient by design in order to prevent a single actor from unilaterally taking control. Next, Bitcoin will be compared to other cryptocurrencies in terms of liquidity, network effects, security, and usage; making the point that no cryptocurrency properties are real unless it is nearly impossible to change them. Finally, the session will conclude with cautionary remarks highlighting that all cryptocurrencies, including Bitcoin, are ongoing socio-economic experiments that could still fail at any point in time, while also highlighting Bitcoin‘s 10+ year track record.
R1x g16 blockchain
Blockchain is a distributed, decentralized public ledger that records transactions in blocks of data that are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. A network of computers validates transactions and adds them to the blockchain, with miners competing to be the first to solve a complex math problem and receive a reward. The blockchain is stored across all nodes in the network, making it difficult to tamper with without altering every copy of the ledger. Applications of blockchain include banking, cryptocurrency, healthcare, and smart contracts.
Introduction of Bitcoin
- Bitcoin is a decentralized digital currency that allows for instant payments anywhere in the world without needing to trust an intermediary. It was first introduced in 2008 by an anonymous author under the name Satoshi Nakamoto. Transactions are recorded on a public ledger called the blockchain to prevent double spending. Users can obtain and trade bitcoins through software wallets, exchanges, ATMs, and other merchants. While bitcoin is used on black markets, normal income rules apply and governments are working to regulate its legal status.

Blockchain: A beginning of Era...
This presentation on basics of blockchain technology which I presented in CSI, Special Interest Group SIG, Innovation & Entrepreneurship. This includes fundamentals, explanation of UTXO, blockchain platforms & demo on Bitcoin full node hosted by us.
Blockchain- describing in brief
Bitcoin-the underlying technology behind the success of cryptocurrencies is termed as Blockchain.
Creating cryptocurrencies is one of the applications of Blockchain technology. Similarly there are other applications of blockchain as well.
blockchain is literally just a chain of blocks
digital information (the “block”) stored in a public database (the “chain”).
Blocks” on the blockchain are made up of digital pieces of information.
• Blocks store information about transactions like the date, time,
• Blocks store information about who is participating in transactions(Instead of using your actual name, your purchase is recorded without any identifying information using a unique “digital signature,” sort of like a username.)
• Blocks store information that distinguishes them from other blocks.
Once an information is stored on a blockchain, it is extremely difficult to change or alter it. Each transaction on a blockchain is secured with a digital signature that proves its authenticity. Due to the use of encryption and digital signatures, the data stored on the blockchain is tamper-proof and cannot be changed.
Simone Bronzini - Weaknesses of blockchain applications - Codemotion Milan 2018
Due to the immutability of the ledger and the difficulty to update their consensus rules, Blockchain applications have many critical layers where a bug can cause huge, irreversible fund losses. This talk will shed some light on why and how Blockchain applications are so critical and will discuss past events that led to fund loss or consensus failures due to bugs in critical parts of the code of Bitcoin and Ethereum applications.
Supply Chain Management on the blockchain with Iot, Azure, BigchainDB, VueJS
In this talk, I'm presenting how to create a simple prototype of supply chain management system built on the blockchain to enable quick traceability.
We'll use a NodeMCU device (ESP8266), a MFRC522 RFID reader, MQTT protocol on Azure, BigchainDB (IPDB with websockets), and VueJS (with vuex, vue-router and elementUI) for the user interface.
TCP/IP of money
This document discusses the history and potential of blockchain technology. It traces the origins of TCP/IP and Bitcoin, comparing Bitcoin to TCP/IP for the internet. Blockchain is described as a transmission protocol, distributed ledger, and stored value account. The document outlines increasing corporate investment and experimentation in blockchain applications across banking, exchanges, infrastructure, and other areas. It argues that blockchain will fundamentally change the financial industry in the same way TCP/IP transformed communication, and that "blockchain is the TCP/IP of money."

Blockchain and Cryptocurrencies
Blockchain and cryptocurrencies are emerging technologies that are still not fully understood. There are differing views on their value. Blockchain is a distributed digital ledger of transactions that is replicated across multiple computers. Cryptocurrencies like Bitcoin use blockchain technology, and their value comes from factors like production costs, scarcity, and utility. Ethereum enables decentralized applications and smart contracts through its cryptocurrency Ether. Altcoins have proliferated since Bitcoin, with some gaining significant value through network effects. Initial coin offerings have also raised billions for new blockchain projects.
Litecoin Crypto Currency Bootcamp
Litecoin Genesis Date - October 7, 2011
Founder Charlie Lee, a former Google and Coinbase employee.
Litecoin reached a $1 billion marketcap in November 2013.[
In May 2017, Litecoin became the first of the top-5 (by market cap) cryptocurrencies to adopt Segregated Witness .
Later in May of the same year, the first Lightning Network transaction was completed through litecoin, transferring 0.00000001 LTC from Zurich to San Francisco in under one second.
Cryptocurrency
Cryptocurrency uses cryptography to conduct financial transactions securely and decentralize control. While initially controlled by a single founder, it has grown to include many alternative coins (altcoins) like Ethereum and Litecoin. Transactions are recorded on a public blockchain to prevent fraud. Cryptocurrencies offer low fees, global access, and pseudonymity compared to traditional currency but are subject to market volatility. Adoption may help the global economy through increased activity, financial access, and transparency of transactions.
crypto ppt.ppt
Rohan provided an overview of how cryptocurrency works including key terms like blockchain, mining, decentralization, and proof of work. Blockchain is a digital ledger that records transactions across a network of computers. Mining is the process of verifying transactions and adding them to the blockchain to introduce new coins as a reward. Decentralization means control is distributed across the network rather than centralized. Proof of work is the consensus algorithm where miners compete to complete transactions. Rohan also discussed advantages like transparency and security as well as challenges like energy use and implementation costs.

It also covers smart contracts and includes quotes from industry experts on the potential for blockchain to transform industries by enabling the "Internet of Value".
BITCOIN EXPLAINED
Bitcoin is a cryptocurrency that was created in 2009 as a decentralized digital currency not controlled by any central authority like a bank. It uses cryptography to secure transactions and generate new units of currency. Transactions are recorded on a public ledger called the blockchain. New bitcoins are "mined" by solving complex math problems, and the total number that can ever be created is limited to 21 million. While bitcoin offers advantages like instant transactions and anonymity, it also has risks like high volatility and the inability to recover funds if private keys are lost.

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.

What's a worker’s market? Job quality and labour market tightnessLabour Market Information Council | Conseil de l’information sur le marché du travail
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.OAT_RI_Ep20 WeighingTheRisks_May24_Trade Wars.pptx

"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.Tax System, Behaviour, Justice, and Voluntary Compliance Culture in Nigeria -...
