A Gentle introduction to Blockchain with EthereumJohann Romefort
This is my gentle intro to blockchain talk given at FC Bayern Hackdays - From the disruption of trust to how to deploy a HelloWorld SmartContract on a local instance of Ethereum using Truffle and Ganache.
These are the slides from my free, introductory Bitcoin class discussing how the network works, why it makes good money, why the network is trustworthy, and how all of this is possible.
If you are new to Blockchain, this intro will guide you through the main concepts, use cases and technologies behind it. Blockchain is a revolution that goes beyond Bitcoins. It will involve the relationships between normal people and governments or established power, other than the way most of the the applications we use today works.
Consider this an effective Blockchain guide for newcomers. These slides have been developed and used in an Open Lesson at the Geeks Academy.
We shortly go through bitcoin/blockchain history before trying to guess how our economy/society will be impacted by this technology in the near future.

https://www.ecurex.com/p2pfisy/
Demonstrating how to create an end-to-end Web-based application that uses blockchain for user authentication, read, and write access to the data stored on the blockchain
There are plenty of bitcoin and blockchain intro decks, so why create another one? Because they are either too technical or too vague on how blockchain actually works! This talk is prepared for audiences who have good educational background and general knowledge about internet. It is used during my trip to Taiwan so some Chinese translations are included. It starts with a basic definition and a functional description of how bitcoin solves the double spending problem, how it was implemented in blockchain, what is mining and why it is critical to the bitcoin ecosystem. Based on these understandings, it goes up a level to talk about how to use cryptocurrencies, the characteristics of a blockchain, and why it has the potential to disrupt financial services and beyond. The talk finishes with an overview of the cryptocurreny market, the rise of Ethereum, and the recent ICO phenomenon. There are several versions of this presentation. This particular version is for financial services professionals so there is more emphasis on blockchain adoption. The CS version covers the math behind mining in more depth, and the general public version provides some cautionary notes regarding speculating on cryptocurrencies. LINE characters are used in illustrations due to their popularity in Taiwan. The American version uses the Simpsons.
This slide contains of a basic introduction about Bitcoin and Blockchain technology covering topics on; what is Bitcoin, how Bitcoin works, who created bitcoin, what is blockchain technology, uses and benefits of blockchain.
In this presentation, Victoria Olsina: SEO expert specialized in blockhain, explore how this groundbreaking tech will affect search engines in the upcoming years.

VCs have for the most part retreated from investing in Bitcoin and Blockchain. The appetite for blockchain products however has only increased. Corporations have formed consortiums such as R3 and the Hyperledger Project to learn more about the technology. Numerous enterprises have rolled out internal pilots to test and explore the applications of blockchain.
At Thomvest, we believe blockchain adoption is about to take off - making it a prime time for VCs to begin making early stage bets.

State of Blockchain 2017: Smartnetworks and the Blockchain EconomyMelanie Swan
Blockchain is a fundamental IT for secure value transfer over networks. For any asset registered in a cryptographic ledger, the whole Internet is a VPN for its confirmation, assurity, and transfer. Blockchain reinvents economics and governance for the digital age. The long-tail structure of digital networks allows personalized economic and governance services. Smartnetworks are a new form of automated global infrastructure for large-scale next-generation projects.
The blockchain is the technology the underpins digital currency (Bitcoin, Litecoin, Ethereum, and the like). The tech allows digital information to be distributed, but not copied. ... You may hear it described as a “digital ledger” stored in a distributed network.
Where is blockchain in comparison to the internet? From insurance, government, gambling, real estate, and other industries, how are they using blockchain? What does this mean for banks, payments, lending, and MSBs? Presented at The Blockchain Series Miami.
The global system behind a viewer’s transaction of watching a movie or TV show impacts viewers and show creators every day. What if all stakeholders had the same facts – Writers, Producers, Directors, Unions, Studios, Networks, Distributors, Theaters, Broadcasters, Cable Providers, Satellite providers, OTT providers and viewers? Blockchains offer precisely this opportunity. In this article we are going to explore new methods for enabling accountability in pre-production, production, post production, distribution, consumption and reporting with a secure chain of custody and metadata to be accessed, including key social attributes such as viewing method, display usage, rights compliance, and digital rights management.

From Bitcoin to Blockchain: Industry Review April 2017 from OLMA NEXT LtdOLMA Capital Management
When the Bitcoin cryptocurrency was released in 2009, its underpinning, the blockchain distributed ledger system was the real technological breakthrough, a formulation that promises to change the basis of all types of transactions globally.
Blockchain technology has paved the way for an Internet of Transactions. Blockchain technology has already proved its worth in such areas as means of payment, interbank exchanges and international remittances. Touted as the next digital revolution, blockchain technology has the potential to transform traditional industries and alter society through disintermediation of trade. Any situation that involves an intermediary that is expensive or fallible represents an opportunity to create a blockchain application case. No industry is immune to the blockchain’s disruption potential.
In 2017, the blockchain technology is at an inflection point. The industry is in a state of transition and must move to Blockchain 2.0, which means the adoption of more sophisticated applications, such as micro-payments and smart contracts. Having outgrown its original bitcoin community, the majority of blockchain applications have yet to pass beyond the prototype stage to make blockchain technology the greatest restructuring technology of the next decade.
Economics, broadly defined, is concerned with the description and analysis of the production, distribution, and consumption of goods and services. Also related is how individuals and groups make choices about these goods and services, and the consequences of their decisions. Decisions might be explicitly in regard to money and resources, but the same principles pertain to any kind of decision. The general form of the problem is that wants are bigger than resources, and even if two choices are both free, there is an opportunity cost in terms of deploying resources or focus into one area and not another. The same structure of decision-making among multiple options, with there being an opportunity cost to the road not taken, may persist regardless of domain, whether in classical economics or distributed ledger economics.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
