GABC2019: Architecting Blockchain applications with Azure Blockchain Workbench by Daniel Szego

With the help of a complete use-case, we will demonstrate how a full blockchain application should be built up from scratch with the help Azure Blockchain Workbench, including but not limited to the smart contract, JSON application model and reporting or power BI integration.

2. DANIEL SZEGO Architecting Blockchain applications with Azure Blockchain Global Azure Bootcamp Zürich B2B Marketplace Institutional traders of a newly formed trade organisation want to create a closed internal marketplace to trade different kind of goods but without a trusted intermediary. The parties can make an offer accept or modify an offer, but the system is visible only for the participants. Payment and settlement is realized by standard banking services, independently of the system. Use Case link: https://github.com/Azure-Samples/blockchain/tree/master/blockchain-workbench/application-and-smart-contract-samples/simple-marketplace Consortium scenario NO: - no cryptocurrency - no public tokens - no public ledger BUT: - identity management - permissions - system integration

4. DANIEL SZEGO Architecting Blockchain applications with Azure Blockchain Global Azure Bootcamp Zürich Ethereum POA 01 A special version of the Ethereum Blockhain based on Parity client. Special characteristics: There is no mining, but a proof of authority consensus, where the a defined number of validator nodes can participate in the consensus in a round robin manner, implying zero priced gas requirement. The governance of the validator nodes is realized with a voting mechanism of the participants. QUICK TIP Try right clicking on a photo and using "Replace Image" to show your own photo.

5. DANIEL SZEGO Architecting Blockchain applications with Azure Blockchain Global Azure Bootcamp Zürich Hyperledger Fabric 02 The Hyperledger project is an incubator umbrella project from the Linux Foundation, containing only consortium distributed ledger technologies: full scale platforms and generic tools for several platfo Fabric: Hyperlegder Fabric is a general consortium blockchain platform. The core architecture contains a splitted consensus mechanism, chains for privacy, membership service provider and certificate authorities for identities.

6. DANIEL SZEGO Architecting Blockchain applications with Azure Blockchain Global Azure Bootcamp Zürich R3 Corda 03 R3 Corda is a distributed ledger technology that were created from the scratch in cooperation with banks and other financial institutes. Corda technology: The technology provides many uncommon elements, like there is no global broadcast, but programmed communication paths, there is no global ledger but bilateral or multilateral facts, code is not law, but atomic prose is included.... Infrastructure templates

13. DANIEL SZEGO Architecting Blockchain applications with Azure Blockchain Global Azure Bootcamp Zürich Workbench 1 Rapid Application Development: create your business workflow with the help of smart contracts and JSON description file and a default UI is auto generated 2 Integrated Identity Management with the help of Active Directory and Key Vault: public keys are associated with identities, private and public keys are stored at key vault. 3 Blockchain information and events are mirrored to a traditional database: possibility for classical reposting or Power BI. 4 Further integration scenarios, like REST API or with Service Bus two directional integration, like Azure IoT.
