Segwit2x –
SegWit2x – A New Statement The Overwhelming power of SegWit2x In order to safeguard the community from an undesired chain split, the upgrade should be overwhelming, but it’s not enough. It should also ‘appear’ as overwhelming. People, businesses and services needs to be certain about what is going to happen and the risks if they won’t follow. My impression is that still too many speaking english people in the western world think the upgrade will be abandoned before or immediately after block 494784 is mined, thus they are going to simply ignore it. That could lead to unprepared patch up and confusion, while naïve users risk to harm themselves. For this reason and for the sake of the Bitcoin community as a whole, we need to show again, clearly and publicly the extent of the support to SegWit2x. We also need to commit ourselves in a widespread communication campaign. I know this is not a strict technical matter, but it could help a lot avoiding technical issues in the future. What we have to do First, we need a new statement from the original NYA signers and all the business, firms and individuals who joined the cause later. That statement should be slightly different from the original NYA though, and I am explaining why. We all know that what Bitcoin is will be ultimately determined by market forces, comprehensive of all the stakeholders involved: businesses, miners, users, developers, traders, investors, holders etc. Each category has its own weight in the process, and everybody has incentives in following the market. -

A Regulatory and Economic Perplexity: Bitcoin Needs Just a Bit of Regulation Daniela Sonderegger [T]here is something special about Bitcoin that makes it inherently resistant to government control. It is built on code. It lives in the cloud. It is globalized and detached from the nation state, has no own institutional owner, operates peer to peer, and its transactions are inherently pseudonymous. It cannot be regulated in the same way as the stock market, government currency markets, insurance, or other financial sectors. —Jeffrey Tucker1 INTRODUCTION Set aside all of the legal and regulatory parameters and simply take a moment to imagine a world that functions on a single digitalized currency, regulated not by a central authority, but rather by the individual users who take part in the system. -
Facilitating Cross-Chain Cryptocurrency Exchanges: an Inquiry Into Blockchain Technology and Interoperability with an Emphasis on Cryptocurrency Arbitrage
Eastern Michigan University DigitalCommons@EMU Senior Honors Theses & Projects Honors College 2020 Facilitating cross-chain cryptocurrency exchanges: An inquiry into blockchain technology and interoperability with an emphasis on cryptocurrency arbitrage Samuel Grone Follow this and additional works at: https://commons.emich.edu/honors Part of the Computer Sciences Commons Facilitating cross-chain cryptocurrency exchanges: An inquiry into blockchain technology and interoperability with an emphasis on cryptocurrency arbitrage Abstract Since the introduction and proliferation of the blockchain-based cryptocurrency Bitcoin, alternative cryptocurrencies also based on blockchain technology have exploded in number. It was once believed that one, or very few, cryptocurrencies would eventually dominate the market and drive out competitors. This assumption, however, was incorrect. Thousands of cryptocurrencies exist concurrently. The vast number of cryptocurrencies leads to a problem—what if the cryptocurrency that an individual possesses does not meet their current needs as well as another cryptocurrency might? The attempt to solve this problem has led to the rise of many cryptocurrency exchanges and exchange schemes. In this paper, we will discuss the motivations for an individual to be interested in exchanging two or more cryptocurrencies by describing and comparing various popular cryptocurrencies with different desirable attributes. While we will discuss these attributes, this paper will give special focus to arbitrage in particular. In addition, we will describe various cryptocurrency exchange schemes and their advantages and disadvantages. Finally, we contribute to the understanding of cryptocurrency exchangeability and interoperability by comparing the historical price data of several cryptocurrencies to determine how often arbitrage has been possible in the past.

Bitcoin, which is the first example of the growing category of money known as the cryptocurrency, is the most popular and widely accepted of them all. Bitcoin is a peer-to-peer electronic cash system that was invented by a software developer called Satoshi Nakamoto, and it is currently taking the lead amongst other digital currencies. It is an electronic payment system based on mathematical proof that is created and held electronically. Bitcoin is also a decentralized form of cryptocurrency that is independent of any central authority – meaning, there is no single institution controlling the Bitcoin network. This eBook is going to help you go beyond a basic understanding of Bitcoin and the mining of it. When you are finished reading, you’ll be ready to get started mining Bitcoins today! 4 What is Bitcoin Mining? In traditional fiat currency systems, money is printed by the government and released into circulation whenever it is needed. -
“The Man Who Really Built Bitcoin: Who Cares About Satoshi Nakamoto
“The Man Who Really Built Bitcoin: Who cares about Satoshi Nakamoto? Someone else has made Bitcoin what it is and has the most power over its destiny” by Tom Simonite, August 15, 2014 [source: http://www.technologyreview.com/featuredstory/527051/the-man-who-really-built-bitcoin/] WHY IT MATTERS The 13 million bitcoins in existence are worth more than $7 billion. In March, a bewildered retired man faced journalists yelling questions about virtual currency outside his suburban home in Temple City, California. Dorian Nakamoto, 64, had been identified by Newsweek as the person who masterminded Bitcoin—a story that, like previous attempts to unmask its pseudonymous inventor, Satoshi Nakamoto, was soon discredited. Meanwhile, the person arguably most responsible for enabling the currency to swell in value to $7.7 billion, and with the most influence on its future, was hiding in plain sight on the other side of the country, in Amherst, Massachusetts. That person is Gavin Andresen, a mild-mannered 48-year-old picked by the real Satoshi Nakamoto, whoever he or she is, as his successor in late 2010. Andresen became “core maintainer”—chief developer—of the open source code that defines the rules of Bitcoin and provides the software needed to make use of it. The combination of Nakamoto’s blessing and Andresen’s years of diligent, full-time work on the Bitcoin code has given him significant clout in Bitcoin circles and stature beyond. The CIA and Washington regulators have looked to him to explain the currency. And it was Andresen who conceived of the nonprofit Bitcoin Foundation—established in 2012—which is the closest thing to a central authority in the world of Bitcoin. -
Trust and Verifiable Computation for Smart Contracts in Permissionless Blockchains
DEGREE PROJECT IN INFORMATION AND COMMUNICATION TECHNOLOGY, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2017 Trust and verifiable computation for smart contracts in permissionless blockchains DOMINIK HARZ KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF INFORMATION AND COMMUNICATION TECHNOLOGY Abstract Blockchains address trust through cryptography and consensus. Bitcoin is the first digital currency without trusted agents. Ethereum extends this technology by enabling agents on a blockchain, via smart contracts. However, a systemic trust model for smart contracts in blockchains is missing. This thesis describes the ecosystem of smart contracts as an open multi-agent system. A trust model introduces social control through deposits and review agents. Trust-related attributes are quantified in 2,561 smart contracts from GitHub. Smart contracts employ a mean of three variables and functions and one in ten has a security-related issue. Moreover, blockchains restrict computation tasks. Resolving these restrictions while maintaining trust requires verifiable computation. An algorithm for verifiable computation is developed and implemented in Solidity. It uses an arbiter enforcing the algorithm, computation services providing and verifying solutions, and a judge assessing solutions. Experiments are performed with 1000 iterations for one to six verifiers with a cheater prior probability of 30%, 50%, and 70%. The algorithm shows linear complexity for integer multiplication. The verification depends on cheater prior probability and amount of verifiers. In the experiments, six verifiers are sufficient to detect all cheaters for the three prior probabilities. Keywords: blockchain; smart contract; trust; multi-agent system; verifiable compu- tation Referat Blockchains adresserar tillit genom kryptografi och konsensus. Bitcoin är den första digitala valutan utan betrodda agenter. -
