On the video, you will see the technical details about the Hyperledger working process. You will understand: why you have to send a transactional proposal. Why you have to verify cryptomaterials and why Read-Write set is complex.
This demo illustrates how one could develop chaincode and applications on the Hyperledger/Fabric, via an example that demonstrates auction of high value items , where multiple participants can work as a consortium taking advantage of the network effect. This demo is build on Hyperledger/Fabric v0.4. It is compatible with v0.5. We will soon have a Hyperledger/Fabric v1.0 version of this demo application. The application source can be accessed at https://github.com/ITPeople-Blockchain/auction
This is a permissioned blockchain explainer video on Hyperledger Fabric.
Blockchain, a completely new architecture for business. Its shared ledger technology establishes trust and transparency, whenever valuable assets are transferred from one party to another. You know for certain that a record — anything from a proof of identity or ownership, to the terms of a business agreement — is unique and unchangeable by any party without the agreement of all parties. With Hyperledger Fabric v1 the promise and potential of Blockchain is becoming more and more reality. In this session, we explore the capabilities of Hyperledger Fabric and we’ll discuss how applications can be built. # Eric Cattoir During a 20 year career at IBM Eric was involved with many customer projects of various sizes. He has a long experience in all kind of development related technologies, rangin...

Within Hyperledger Fabric, a developer is going to need to really understand the application and smart contract. Here we look at an example the blockchain and world state in the ledger with how this integrates with the smart contract and application. The developer will also going to be understanding built in integration method such as events, transformation and calling out directly from the smart contract with this last option having the possible issue on non-deterministic results which will not reach a consensus.

Hyperledger Composer allows you to quickly build and test Blockchain applications. In this video I'll show you how to put together everything you've learned so far in the tutorial This video accompanies Part 3 of the Hyperledger Composer Tutorial series from IBM developerWorks A link to the tutorial is in the video description Here's what I'll show you in this video: -Clone the iot-perishable-network from GitHub - Make changes to the iot-perishable-network model - Add chaincode for new transaction I add to the model - Modify the network's permissions to restrict access based on participant - Then I'll add Cucumber tests to unit test the network - Build the network and run the unit tests - Deploy the network your local Fabric - Issue IDs for all the participants in the network, and - R...
In this video you will see: - who is staying behind the Hyperledger and what exactly is Hyperledger Fabric
In this video we look at how consensus is achieved in Linux Foundation Hyperledger Fabric. First taking a look at what is a Peer and a Node with their differences then step through the process from submitting a transaction from a client app to creating a block on the chain and confirming consensus. We see how some privacy is achieved with only specific participants running the transaction against the smart contract (more privacy in following videos) and how being in a private blockchain enables us to limit the compute power by using a number of endorsers to commit a transaction opposed to the whole network solving a cryptographic puzzle.

This Proof of Concept demonstrates the use of Hyperledger Fabric (Blockchain) to provide a decentralized ledger shared among Regulators, Hospitals, Medical Schools, and Payors. Its Blockchain database contains nearly 750,000 Physicians, 5,000 Hospitals, 400 Medical Schools, and 50 Regulators with almost 10,000 user accounts. Each Hospital, Medical School, and Regulator has 2 user accounts demonstrating both data access and functionality security embedded in the smart contract. Login using GUEST and GUEST and then view the INFO page for instructions. GUEST represents a Payor (or the public). Anyone can login to the Belltane or Byrlin web applications as any user. All user passwords are the username and GUEST can view all users and passwords. https://bpn-dev-web.belltane.com https://bpn-d...
This is mobile (android and iOS) feedback app created using ionic 3 application in client side and Node.JS in server side. We are using Hyperledger Fabric as blockchain technology as distributed database. This app will empower the people by leveraging the security and anonymity of decentralized systems. It enables users to file an anonymous feedback or report an incident anonymously pertaining to areas of Governance, Police or Administration. It is fully decentralized hence tamper-proof by any authority. Technology used 1. Ionic 3 (Angular 4 + TypeScript + Jquery + HTML + CSS etc); 2. Node.JS as backend library + Express.JS as backend framework. 3. Blockchain technology - Hyperledger fabric - Chaincode - Golang - Docker
https://developer.ibm.com/tv/the-creation-of-hyperledger-fabric-v1-for-stable-blockchain-networks/ Hyperledger is one of the fastest growing open source blockchain communities. Anyone can help lead it. Learn more and join the community: www.hyperledger.org. Or, head here, http://ibm.co/2dbtffw. The work started last year with a simple framework to test the interaction between applications and secure blockchain networks, and it’s allowed us to test use cases in supply chain, capital markets, manufacturing, and healthcare. First, we learned that permissioned blockchain networks that require every peer to execute every transaction, maintain a ledger and run consensus can’t scale very well and can’t support true private transactions and confidential contracts. So the Hyperledger community d...

Demo of how IBM and Maersk are digitizing and simplifying global trade to create trust and transparency in the supply chain using blockchain technology--a distributed, permissioned platform accessible by the supply chain ecosystem designed to exchange events data and handle document workflows. The example shows how shipping flowers can create trust and security in a digitized workflow while improving efficiencies of global supply chains.

Mainstream adoption of blockchain technology in the enterprise ecosystem has been impeded due to inherent limitations of scaling individual blockchain networks. We are introducing AION – a multi-tiered blockchain system designed to address some of these core challenges. Core to our hypothesis is the idea that many blockchains will be created to solve unique business challenges, within unique industries. As such, the AION Network is designed to support many custom blockchain architectures, while providing a trustless mechanism for cross-chain interoperability. By utilizing our concept of “bridges”, this multi-tiered blockchain model will allow the creation of layers of connecting blockchain networks that are able to communicate and transact among each other.

This is a demo of freeform exchange of digital assets between 11 companies on a permissioned blockchain network using Hyperledger Fabric.
Looking at the major differences between a private Blockchain with a public blockchain. Within a private blockchain we also know the participants in the network so we take a look at how we add a new participant into a blockchain network to know who they are.
