This document discusses alternatives to Bitcoin cryptocurrency design. It summarizes Litecoin, which uses a different proof-of-work algorithm called Scrypt, allowing for faster transaction confirmations. Ripple is described as eliminating proof-of-work entirely, reaching consensus through a variation of Byzantine Paxos voting among servers. Ethereum allows for distributed applications through a scripting language and features a more complex mining reward system than Bitcoin. Common security issues with smart contracts are also outlined.
The document provides definitions and explanations of key concepts related to blockchain technology and cryptocurrencies like Bitcoin. It discusses how blockchain works as a distributed ledger using cryptography and consensus to allow decentralized transactions without intermediaries. It also addresses common questions around how Bitcoin transactions are validated and added to the blockchain through mining processes.
Bitcoin and other distributed virtual currencies are revolutionizing how monetary value is stored and exchanged on the Internet. Key opportunities and risks will be described. The two main objectives of this talk will be to explain the underlying blockchain and cryptology technologies that make them work, and to demonstrate PHP recipes for using the web services that enable payment processing, identity validation, and smart contract execution.
The document discusses blockchain and how it works. It explains that blockchain provides transparency through a distributed ledger, but questions whether the information is accurate and secure. It then describes how the consensus protocol and hashing establish accuracy by validating new transactions and blocks across all nodes. Immutability is achieved through the blockchain, where each new block contains a hash of the previous block. The longest chain provides security against double-spend attacks by waiting for transactions to be confirmed across multiple blocks. Other topics covered include permissioned vs private blockchains, smart contracts, sectors that will be impacted like payments and identity, and how businesses can prepare for blockchain.
Blockchain and cryptocurrencies like Bitcoin enable new forms of digital money and financial contracts. Bitcoin introduced a trustless digital currency using cryptography to secure a distributed public ledger called the blockchain. Miners on the Bitcoin network process transactions and add them to blocks which get added to the immutable blockchain roughly every 10 minutes. Over time, the blockchain has grown large as a record of all transactions, posing scalability challenges. New applications like smart contracts and alternative currencies like Namecoin build on this innovation to enable decentralized applications and services.
The Blockchain - The Technology behind Bitcoin Jérôme Kehrli
The blockchain and blockchain related topics are becoming increasingly discussed and studied nowadays. There is not one single day where I don't hear about it, that being on linkedin or elsewhere.
I interested myself deeply in the blockchain topic recently and this is the first article of a coming whole serie around the blockchain.
This presentation is an introduction to the blockchain, presents what it is in the light of its initial deployment in the Bitcoin project as well as all technical details and architecture concerns behind it.
We won't focus here on business applications aside from what is required to present the blockchain purpose, more concrete business applications and evolutions will be the topic of another presentation I'll post in a few weeks

UTD. This presentation contains a mini lesson on cryptocurrencies for beginners/experts!
This document discusses key concepts related to decentralized networks and blockchain technology. It begins by describing the basic components of a blockchain network, including nodes that exchange information and maintain an identical and immutable record of historical data. It then explores the differences between decentralized, fractal, distributed, and diversified network types. The document also notes some potential problems with decentralization, such as centralized elements like mining pools, hardware manufacturers, and exchanges. Finally, it provides an overview of distributed ledgers, peer-to-peer networks, and defines blocks and blockchains as sequences of immutable records of transactions.
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.
Bitcoin is a digital currency, created by an unknown person, controlled by no one. It's as mysterious as it is popular. But what is it really.
I gave this presentation both to a group of venture capitalists and at the Intro2 Meetup in Silicon Valley.

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.
Toward Money-over-IP? From Bitcoin to M2M MoneyGeorge Giaglis
How will Bitcoin and Blockchains disrupt industries, such as banking, and create a wave of new machine-to-machine applications on nano-payments and autonomous digital corporations.
Metadata in the Blockchain: The OP_RETURN ExplosionCoin Sciences Ltd
With the addition of OP_RETURN outputs in version 0.9, it became possible to attach arbitrary pieces of information to bitcoin transactions. This turns bitcoin into a low-level communications protocol, just like TCP/IP, on which many new applications can be built.
Despite its powerful features, bitcoin is also limited, costly and inefficient compared to TCP/IP. After discussing which sorts of applications make this trade-off worthwhile, we talk about CoinSpark, a new open source protocol for enhancing bitcoin transactions, which makes extensive use of OP_RETURNs.
Virtual or digital currencies, with Bitcoin chief amongst them, have been gaining momentum and investment over the last couple of years. Offering an almost costless means of making payments around the globe, virtual currencies have the potential to bring significant disruption to the banking industry. This potential is not lost on either Bitcoin startups or banks themselves. But how does Bitcoin actually work? A peer-to-peer network maintains the “blockchain”, an innovative cryptographic protocol which securely mediates payments between parties without mutual trust. This session will step through the structure of the blockchain, showing how it solves the “double spend” problem and allows decentralised processing of financial transactions. Whether Bitcoin will become the currency of the internet or it’s a bubble that is doomed to burst sooner or later, the blockchain itself will change the face of transactional banking and perhaps other industries along the way.
Presentation to the Sydney Financial Mathematics Workshop (11 March 2015)
http://www.qgroup.org.au/content/bitcoin-banking-and-blockchain
Blockchain basics are explained in the document. It discusses that blockchain technology was first conceptualized by Satoshi Nakamoto to provide an alternative payment system. It focuses on blockchain's core elements as a distributed ledger for transactions. Blockchain allows value transfer without permission of a third party through decentralization and recording/validating every transaction with miners, making transactions immutable and preventing hacking. It also discusses key components like blocks, hashes, proof of work, blockchains and different types of blockchains like public, private and hybrid.
Is cryptocurrency really the future of money? Bitcoin is the first and most famous cryptocurrency that exploded in late 2013 when the price per Bitcoin exceeded $1200. This is an explanation of what cryptocurrency is and how payments are processed
Today, blockchain technology doesn't need to be implemented. A word that once was foreign has now earned accolades from individuals across the globe. This technology is being talked about by every business and investor. Blockchain started its journey as an underlying Bitcoin exchange technology, and it has gained so much popularity over the years. Everyone speaks about Blockchain, from students to working professionals; but what makes Blockchain so attractive is that you need to know the concepts of Blockchain technology for this.
This slidedeck was used at the first Blockchain Vlaanderen meetup in Leuven. It features a live (and open-source) demonstration of two usecases with Multichain.
Dash uses a two-tier network of masternodes to enable features like instant transactions, private transactions, and decentralized governance. Masternodes require a collateral of 1000 Dash to participate. They facilitate features like InstantSend for near-instant confirmations and PrivateSend for concealing transaction histories. The masternode network also funds projects and oversees governance through a decentralized budget and voting system. Dash aims to further develop these capabilities and improve scalability with upgrades like Evolution scheduled for 2018.
This document summarizes the state of Ethereum and cryptocurrency mining in 2014. It discusses features enabled by Ethereum like decentralized applications and smart contracts. It outlines progress made in technical areas like client implementations and applications built on Ethereum. It also discusses challenges remaining around efficiency, security, and client implementations. The document concludes that Ethereum is at the halfway point and more work is needed to address remaining issues.

This document provides an introduction to blockchain technology. It defines blockchain as a distributed database of records stored in immutable blocks connected with prior blocks forming a chain, where the validity is affirmed by peers in a decentralized network secured by cryptography. It discusses key aspects of blockchain including decentralization, transparency, immutability, consensus mechanisms, and applications such as financial transactions, digital identity, and peer-to-peer networks. Permissioned blockchains are also covered as a way to allow distributed transparency and immutability while controlling access. Regulatory compliance is noted as an important consideration for blockchain implementations.

Blockchain Use Cases: Think of a "Public" Pub/Sub QueueAltoros
The document discusses several perspectives on blockchain use cases from SWIFT Institute, Accenture, and potential adoption scenarios. SWIFT Institute found little short-term payoff for securities transactions due to challenges like regulatory support. Accenture saw opportunities but said the technology is not mature enough. The document then presents a simple use case of blockchain as a public pub/sub message queue and discusses the technical advantages and challenges. It concludes by considering which industries and organizations may be early blockchain adopters.
This slide is a entry level introduction to blockchain security, it illustrates the current status of the issue, summarises attack methodology, and reviewed a few past hack cases.
Explains what the Blockchain is and how it works. Features slides about the Cryptography, P2P Networking, Blockchain Data Structure, Bitcoin Transactions, Proof of Work Algorithm (Mining) and Scripts.

Independent Study - College of Wooster Research (2023-2024) FDI, Culture, Glo...AntoniaOwensDetwiler
"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.

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.
