The ABC of Blockchain Tech : Crypto,NFTs and the UN SDGsJonathan Ajah
Blockchain, cryptocurrency, and NFTs are emerging technologies that are transforming industries. Blockchain is a shared, immutable ledger that facilitates recording transactions and tracking assets across a network. There are different types of blockchain networks including public, private, permissioned, and consortium blockchains. Cryptocurrencies utilize blockchain technology, with Bitcoin being the first and largest, while NFTs represent unique digital assets. Blockchain is evolving through different epochs as its applications expand beyond financial services into other areas like healthcare and supply chains. Emerging markets may see benefits of these technologies to drive development.

W24717 economic limit of bitcoin dan blockhainRein Mahatma
This document analyzes the economic limits of Bitcoin and blockchains through three equations:
1) A rent-seeking competition equation showing that the reward for mining must be fully dissipated by mining costs. This implies mining rewards must be large relative to costs.
2) An incentive compatibility equation showing that the costs of manipulating the blockchain through a majority attack must exceed the benefits of attacking it. This implies costs are related to ongoing mining costs.
3) Combining the first two equations implies that ongoing mining rewards must be large relative to the one-time benefits of attacking the blockchain. This suggests Bitcoin may face economic limits to how important it can become due to incentives for majority attacks.

What is a "Smart Contract"?
What Smart Contracts are useful for?
How to improve business processes using Smart Contracts?
Ethereum is a decentralized blockchain network that allows for smart contracts and decentralized applications. Developed in 2015, it is now the second largest cryptocurrency after Bitcoin. Ethereum uses its own cryptocurrency, Ether, and programming language called Solidity to power a virtual machine that facilitates smart contracts, which are programs that automatically execute the terms of an agreement. Popular uses of Ethereum include non-fungible tokens (NFTs), decentralized finance applications, and facilitating transactions through paid computational fees called "gas".
Explain Ethereum smart contract hacking like i am a fiveZoltan Balazs
Ethereum allows for smart contracts which are programs stored on the blockchain that execute automatically based on predefined rules. Smart contracts are vulnerable to hacking through bugs and exploits like integer overflows. Major hacks have occurred on smart contracts, like The DAO hack which stole $50 million worth of ether. Writing secure smart contracts is challenging as seen through continued hacks, showing the technology is still immature.

Cryptography is used to secure information and maintain decentralization in cryptocurrencies. The main encryption methods used are hashing, symmetric cryptography, and asymmetric cryptography. Cryptocurrencies differ from traditional currencies in their creation, transfer processes, and benefits like empowering users, faster transfers, access for unbanked people, reduced corruption, and inflation resistance.
This document discusses how blockchain technology could transform personal insurance. It begins by explaining blockchain technology and how it provides a secure public ledger without a central authority. It then discusses personal insurance and the role of trusted third parties. Blockchain technology could displace some roles of third parties by preventing duplicate transactions and providing a verifiable transaction record. The document explores four themes regarding how blockchain could impact identity, transactions across space, recording of debts over time, and enabling new forms of mutual insurance communities. It provides examples of how blockchain could be used to manage personal identity and data, enable more global insurance products, automate processes like wills and life insurance payouts, and transform insurance models.

Plenary Talk at ICEIC 2019
Pullman Auckland Hotel, Auckland, New Zealand

Abstract
In the year 2018, we have witnessed the surge and the fall of crypto-currencies. With the surge, blockchain the new technology behind cryptocurrencies, and its idealistic footprint of advanced thoughts, blockchainism it can be perhaps called, came to enthrall our minds. Thousands of new ambitious projects have been conceived and fast activated with the worldwide frenzy of new funding through initial coin offerings a novel funding mechanism in the blockchain world. Decentralized societies, equal accesses to valuable resources, reducing the cost of middleman, freed individuals from hierarchical organizations, and reducing the spread in inequalities are some of those advanced thoughts. But the fall came; the market value for Bitcoin has collapsed more than 7 times from its peak-value; that of Ethereum has plummeted more than 12 times. These two power houses which have supported those progressive projects are now torn apart. Recent New York Times report reads, “Blockchain: What’s it good for? Absolutely nothing, report finds.” Another one reads, The Blockchain Is a Reminder of the Internet’s Failure. The same utopian promises that bloomed during the Internet’s early days are back. Be afraid.“ Should this be the end of our pursue to change and make a better world with blockchains? Obviously not. In this presentation, I would like to talk about the reality of blockchain technology and how distant it is from the ideals. With this accessment, I would like to present some of novel research progresses we made in year 2018 and talk about further research ideas to pursue in year 2019.
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.
This presentation is about blockchain.
When Thomas Edison invented the electric lamp in 1879, he did not make a market analysis. The market did not have an identified need for a lamp but for light. This is a kind of disruptive original ideas.
Satoshi Nakamoto (a person or a group) did not do a market analysis neither . The blockchain was born after the financial crisis of 2008 as people lost trust in banks.
Satoshi Nakamoto introduced a new model of trust based on cryptographic proof in a decentralised & distributed ledger.
What is bloackchain technology ? Why blockchain is disruptive? And what are the main blockchain technologies ?
The document discusses blockchain technology and its ideals versus reality. It begins with an abstract noting the surge and fall of cryptocurrencies in 2018. While blockchains were initially seen as a way to create decentralized societies and reduce inequality, in reality blockchain networks have become re-centralized with mining dominated by a few sites. The document then provides background on blockchain technology and how it works in theory versus practice. It discusses some of the challenges blockchains face regarding scalability and decentralization. The speaker proposes two novel approaches to address issues of re-centralization and the scalability trilemma. The talk aims to provide a realistic assessment of blockchains and discuss ongoing research directions.
The document discusses blockchain technology and its potential to create a more decentralized society. It introduces Sota Watanabe and their work with Chronicled on supply chain solutions using blockchain, IoT, and AI. It then discusses Watanabe's motivation from an experience in India and desire to give more power to individuals through decentralization.
Implementing Commerce in the 21st century with Blockchain and CryptocurrenciesPayson Johnston
This document provides an overview of blockchain technology and cryptocurrencies presented by Payson Johnson, CEO of Crowdz. The presentation covers the basics of blockchain, how it operates as a distributed network without central authority, and applications for commerce. It also discusses cryptocurrencies, different types of cryptos, and implications for industries like banking and supply chain management. Blockchain enables secure payments and smart contracts through distributed ledgers that create permanent, tamper-proof records of transactions.
Introduction to blockchain is a presentation to demystify distributed ledger technology. Show and explain how the technology behind Bitcoin works and what are the pros and cons of it (at the time of creating this presentation June 2018)
Paradigm shift: from the bitcoin Blockchain to Networked Computingkumar641
The document discusses the history and evolution of blockchain technology from Bitcoin to current applications. It begins with the origins of Bitcoin and cryptocurrency starting in the 1980s. It then summarizes the key events in Bitcoin's launch and growth, and discusses how blockchains can be used for more than just currencies. Blockchains allow for the creation of verified, immutable transaction logs across decentralized networks. The document concludes by discussing Swerl's focus on using blockchains for networked computing and information provenance across organizations and devices.
Blockchain Crypto Jamming: Subverting the Instrumental Economy
The ultimate subversion is money, refusing the pecuniary resources of the state. This project applies a philosophical and critical theory lens to examine the use of nomenclature in one of the most radical longitudinal transformations in contemporary times, the shift away from state-run monetary resources towards cryptocurrencies and smart contracts in citizen-determined decentralized financial networks.
A Cryptoeconomic Theory of Social Change is presented in which linguistic progression serves as a tracking mechanism. The steps to lasting change have their own vocabulary (Brandom). First, there is the social critique, the complaint about what is wrong, the negative side (Adorno and Horkheimer highlight instrumental reason and the empty culture industry). Second, there is the antidote, an alternative that can overcome the complaint, the positive side. Third, the solution becomes the new reality, and as a consequence, the whole of reality is now seen in this context, adopting its vocabulary (“fiat health” system for example, referring to the antiquated method). The social movement graduates from language game (Wittgenstein) to form of life (Jaeggi).
Blockchains are Occupy with teeth, notable in the level of personal responsibility-taking by individuals to steward their own financial resources. The crypto citizen is not merely trading CryptoKitties and Bored Ape Yacht Club tokens, but getting blocktime loans through DeFi liquidity pools instead of fiat banks, earning labor income in crypto, and shifting all economic activity to blockchain networks. The artworld signals mainstream acceptance with Christie’s non-fungible token digital artwork auctioned from Beeple for $61 million. At the global level, coin communities constitute a new form of Kardashev-level (planetary-scale) democracy. Blockchains emerge as a robust smart network automation technology for super-class projects ranging from space-faring to quantum computing and thought-tokening. The further stakes of this work are having a language-based theory of social change with broad applicability to social transformation.

A blockchain is a distributed ledger that records transactions across a peer-to-peer network. It uses cryptography to allow participants to interact securely and anonymously to validate transactions without a central authority. The technology began with Bitcoin and enables applications like cryptocurrencies, smart contracts, and decentralized databases. Understanding blockchains requires grasping both technical aspects like distributed databases and consensus algorithms, as well as philosophical concepts like disintermediation.
This course covers in detail the technical principles & concepts behind blockchain. In addition, it seeks to provide you with the insights and deep understanding of the various components of blockchain technology, and enables you to determine for yourself how to best leverage and exploit blockchain for your project, organisation or start-up.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
