Building a Blockchain in Under 15 Minutes - Programmer explains
 
14:28
I wanted to demonstrate that the concept of a blockchain that powers almost all of the modern cryptocurrencies is very simple at its core. Bitcoin, Ethereum, Litecoin etc all are based on this blockchain technology. Many people think that the blockchain is a complicated thing while at it's core its just a clever use case of hashes.

Developing Blockchain Software
 
59:37
This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges. Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns. C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do.

Blockchain, A Developers Perspective
 
44:13
Andrzej Grzesik Great Archwizard You might have heard about Blockchain… As engineers, we prefer to talk facts, so I will start with the foundations, explaining the term and concepts. Then we will build a 'smart contract' application, in Java, using open source. Then consider the implications of the contract being put out "there", and what is "there". You will walk out understanding what a 'distributed ledger' is, maybe an idea of an application, who knows?

Blockchain tutorial 11: Elliptic Curve key pair generation
 
18:58
This is part 11 of the Blockchain tutorial explaining how the generate a public private key using Elliptic Curve. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

Blockchain as a Service: Building Blocks of Blockchain
 
34:52
Blockchain as a Service: Building Blocks of Blockchain [B] - Gary White Jr., Dell EMC Blockchain is among the hottest technologies in the market place today. Blockchain has the potential to change how we transact business on the internet, empowering users to make secure transactions online without the need to have a third party oversight. For all its benefits Blockchain is still a relatively new technology and most people don’t know how they would practically use it. In this talk we will deep dive Blockchain implementations; explaining how they work and demonstrate how we have integrated these with Cloud Foundry. At the end of this talk you will have a clear understanding of the Blockchain technology and how your Cloud Foundry applications can take advantage of it. Gary White Jr. Dell EMC Software Engineer II I work for DellEMC on the Dojo team in Cambridge, MA. We have been working on open-source projects like the Bosh-RackHD-CPI since our team's beginning, and also worked with Persistence in Cloud Foundry for the better part of last year. One of our more recent projects was a POC for storing data into a Blockchain using Cloud Foundry.

J-Spring 2018: Emond Papegaaij - Hyperledger Fabric and Java
 
51:47
Blockchain is the hype of the moment. Seemingly everything gets better with blockchain and company values skyrocket when including blockchain in their name. Although many of these stories may have to be taken with a grain of salt, blockchain technology itself is a very interesting development. To find out more about the possibilities, we decided to go on a journey of exploration in this strange world. This journey led us from certificate authorities, peers, orderers, experimental builds, endorsement policies to even more strange places with which it will be hard to impress anyone in your social life. Still, I would like to take you with me in this story about Hyperledger Fabric and Java. Hyperledger is part of the Linux Foundation and houses and promotes various open source blockchain initiatives. Fabric is a blockchain framework developed by IBM and with its 1.1 release it is one of the more mature projects within Hyperledger. It has a very flexible architecture where you can write smart contracts in Go, Javascript, and for the bravest among us, also in Java. The latter is not officially supported and requires an experimental build. Which of course provides more fun to play with as a real techie. Thanks to the Java SDK for client applications, you can do cool things with blockchain without leaving the comfort zone of Java. The learning curve is quite steep and includes a wild jungle of terms such as endorsement policies, shims and orderers. Fortunately, you can now attend a presentation about all this. A blockchain application is not your average CRUD application. Interaction with a blockchain is very different from interaction with a (No)SQL database. You have to continuously consider endorsement policies (there’s that term again) and the possibility that different peers do not share their opinion about a certain transaction. Also the code that runs within the blockchain, the Chaincode, is special. The environment in which Chaincode operates is very limited in its interactions with the outside world. Messages come in, answers go out and you have access to the world state. You will therefore have to think carefully about the structure of these three components. In addition, the deployment model is very different from what we are used to in the Java world. Especially upgrading the Chaincode and the permissions and policies certainly deserve some special attention. Since there is plenty to tell about Hyperledger Fabric and Chaincode, I will not introduce blockchain itself. You do not have to be an expert in this field, but I do expect you to be familiar with the principles. If you have any doubts about this, read the IBM E-Book Blockchain for Dummies briefly. That should provide enough foundation to attend the presentation. Bio Emond: Emond Papegaaij is een Plain Old Java Ontwikkelaar bij Topicus Security en de grondlegger van de Identity & Access Management oplossing Topicus KeyHub. Ook is hij een actief lid van de open source community, waar hij onder andere committer is op Apache Wicket. Al sinds zijn studie Technische Informatica aan de Universiteit Twente heeft hij al een voorliefde voor wiskunde. Cryptografie, waar blockchain zwaar op steunt, valt dus helemaal in zijn straatje.

There is more to blockchain than Bitcoin, Ethereum and all the mining! Let's see how do these technologies can affect us, developers. This session starts with facts, establishing what blockchain, smart contracts and other concepts are. Armed with theory, we will showcase a 'smart contract' application, built in Java, with open source, then discuss applications, problems and consider implications of a contract being put 'out there' (and what is 'there') You will walk out understanding what a 'distributed ledger' is, knowing what to get from Github. And maybe an idea of an application, who knows? Let's now build those revolutions everybody is speaking about!

#11Crypto Force - CppCon 2016 David Schwartz “Developing Blockchain Software”
 
01:16:05
Topic of today's video: CppCon 2016 David Schwartz “Developing Blockchain Software” Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/cppcon/cppcon2016 — This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges. Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns. C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do. The primary purpose of the talk is to explain what blockchains are, increase understanding of the unusual challenges developers of blockchain software experience, and to demonstrate why C++ is a good choice to address them. — David Schwartz is the Chief Cryptographer of Ripple, a distributed payment network. Also known as "JoelKatz", he is a respected voice in the crypto-currency community. David has also developed secure messaging and cloud storage software for government and military applications.

Blockchain tutorial 17: Generate Bitcoin address
 
19:39
This is part 17 of the Blockchain tutorial explaining how to generate a Bitcoin address using an online tool. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

2017-07 gRPC 101 for Java Developers
 
01:10:50
gRPC is a high performance, open source, general RPC framework that puts mobile and HTTP/2 first. gRPC is based on many years of Google's experience in building distributed systems - it is designed to be low latency, bandwidth and CPU efficient, to create massively distributed systems that span data centers, as well as power mobile apps, real-time communications, IoT devices and APIs. It's also interoperable between multiple languages. But beyond that fact that it's more efficient than REST, we'll look into how to use gRPC's streaming API, where you can establish server-side streaming, client-side streaming, and bidirectional streaming! This allows developers to build sophisticated real-time applications with ease. In addition to learning about gRPC and HTTP/2 concepts with code and demonstrations, we'll also deep dive into integration with existing build systems such as Maven and Gradle. We'll look at: • Configuring projects to generate gRPC stub code • Using Protobuf3 to define services • Creating synchronous and asynchronous services, with streaming. • Load balancing • Deadlines & Context Propagation About the speaker: Ray is a Developer Advocate for the Google Cloud Platform. Ray had extensive hands on cross-industry enterprise systems integration delivery and management experiences during his time at Accenture, managed full stack application development, DevOps, and ITOps. Ray specialized in middleware, big data, and PaaS products during his time at Red Hat while contributing to open source projects, such as Infinispan. Aside from technology, Ray enjoys traveling and adventures.
