In late 2017, a growing number of customers were interested in using Hyperledger Fabric (HLF) to build their applications on Azure. At this time, we announced support for this popular offering through the Azure Marketplace. Over the early part of this year we added support for Visual Studio Code (VS Code) and the Go extension for VS Code, which enabled users to both deploy a HLF network and write chain code in Go on Windows, Mac, and Linux.
We are happy to share a series of new enhancements for developers building solutions using Hyperledger Fabric on Azure.
Updated template for Hyperledger Fabric 1.3
Today, we’re sharing an updated template for Hyperledger Fabric that you can download from the Azure Marketplace. This version includes:
Hyperledger Fabric version 1.3 support Unified template to allow both single VM (multi container) development and multi VM (scale out) models The ability to connect multi-subscriptions via a private connection, automated by the template Orderers run by using a full, highly available Kafka backend for production quality deployments Peers run using either LevelDB or CouchDB for persistence and to enable analytics
Completed documentation for the architecture can be found on GitHub. This is the initial release of
We’re happy to announce the release of Azure Blockchain Workbench 1.6.0. It includes new features such as application versioning, updated messaging, and streamlined smart contract development. You can deploy a new instance of Workbench through the Azure portal or upgrade existing deployments to 1.6.0 using our upgrade script.
Please note the breaking changes section, as the removal of the WorkbenchBase base class and the changes to the outbound messaging format will require modifications to your existing applications.
This update includes the following improvements:
One of the most popular feature requests from you all has been that you would like to have an easy way to manage and version your Workbench applications instead of having to manually change and update your applications as you are in the development process.
We’ve continued to improve the Workbench development story with support for application versioning with 1.6.0 via the web app as well as the REST API. You can upload new versions directly from the web application by clicking “Add version.” Note that if you have any changes in the application role name, the role assignment will not be carried over to the new version.

“Developers! Developers! Developers!” That phrase is synonymous with Microsoft’s history of democratizing complex technologies and empowering anyone with an idea to build software.
Over four decades, we’ve lowered barriers to development with developer tooling, enterprise integration, DevOps, PaaS, and SaaS. Today, serverless offerings from Functions and Logic Apps to Azure DevOps and IoT Central remove friction for development in the cloud.
This morning, we’re excited to announce the initial release of the Azure Blockchain Development Kit which is built on Microsoft’s serverless technologies and seamlessly integrates blockchain with the best of Microsoft and third-party SaaS.
This kit extends the capabilities of our blockchain developer templates and Azure Blockchain Workbench, which incorporates Azure services for key management, off-chain identity and data, monitoring, and messaging APIs into a reference architecture that can be used to rapidly build blockchain-based applications.
These tools have become the first step for many organizations on their journey to re-invent the way they do business. Apps have been built for everything from democratizing supply chain financing in Nigeria to securing the food supply in the UK, but as patterns emerged across use cases, our teams identified new ways for Microsoft to help developers go farther, faster.
On behalf of the entire Workbench team, thank you for your continued support and interest in Azure Blockchain Workbench. With every month’s release, our focus areas are driven by the topics you care about the most. Workbench 1.5.0 focuses on two key themes, making Workbench easier to deploy and simplifying the process of developing and testing your end to end blockchain solutions.
Whether you’re a new customer or upgrading your current deployment, we hope you like what we have built.
The previous Workbench installation provided a lot of flexibility that most people didn’t need. We have streamlined the deployment template with default values and easier Azure Active Directory (AAD) integration. For advanced users, you still have customization options available within the template. For customers with higher scale needs, we also have newly published guidance on how to scale your deployment.
Develop and troubleshoot easier
You’ve told us that Workbench helps you build and deploy blockchain applications faster, but you would like more help with debugging issues in your contracts and your integration code. We’ve added guidance on how to use Application Insights to troubleshoot issues, added robust telemetry, and more targeted error messages to help you pinpoint issues
At DevCon in 2015, I announced support for Ethereum on Microsoft Azure. It was a humble beginning consisting of a private Ethereum network and a corresponding “Hello World” smart contract. Now in 2018, Azure supports all the major blockchain platforms and can deploy a wide variety of network configurations from a lab environment to more sophisticated consortium networks targeted at production workloads.
Since that time, we have engaged with hundreds of customers across every industry and every corner of the world. We have learned a lot about what business scenarios are viable and what it truly takes to deliver an end to end blockchain solution.
A key learning has been what it takes to build and establish blockchain networks. We strive to improve the overall lifecycle of these networks with better management capabilities, governance frameworks, and integrations with the cloud services needed to build dapps. One of the most impactful observations we have shared with the broader community is a requirement for untrusted networks to support robust applications with multiple participants using varying trust model’s privacy for its participants and potentially outcomes.
The previous statement might seem simple at first, but it’s quite complex if you examine some of the
Nasdaq revolutionized financial markets in 1971 by opening them up to millions of individual investors with the world’s first-ever electronic stock exchange. Since then, the company’s innovative spirit has kept them on the leading edge of technology evolution in capital markets, while transforming the brand into a powerhouse technology provider.
Nasdaq’s commercial technology arm, Market Technology, powers mission-critical capital markets infrastructure at more than 100 exchanges, clearinghouses, and central securities depositories across 50 countries.
To better serve its global clientele, Nasdaq re-architected its enterprise offerings and released the Nasdaq Financial Framework (NFF) in 2016. The Framework’s modular design leverages a single operational core that powers a vast portfolio of business applications and services across the trading lifecycle, enabling Nasdaq customers to easily add, remove and amend their mission-critical technology stack without the cost and complexity associated with monolithic infrastructure systems.

The Web client gives you an easy to use the environment to validate, test, and view blockchain applications. The application interface is dynamically generated based on smart contract metadata and can accommodate any use case. The client application delivers a user-facing front-end to the complete blockchain applications generated
Development and deployment of Ethereum based applications, commonly referred to as DApps, can be a challenging task for developers. With over 1 million downloads, Truffle has proven to be a premier suite of tools that can be used for developing smart contracts and DApps for both the public Ethereum network on main-net as well as private consortiums.
Truffle streamlines the process of recognizing changes, migrating them to the underlying blockchain, and providing a framework to allow a rich debugging experience with common step through of code and inspection of low-level components.
The Truffle Suite fits very nicely with the products that Microsoft is building to help developers build end to end solutions on Ethereum. For example, when building solutions leveraging Azure Blockchain Workbench, a key component is creating the underlying smart contract(s). Using Truffle framework to build, test, and maintain the smart contracts, which will be uploaded to Azure Blockchain Workbench, makes the process for developers and IT Pros a streamlined process.
The team at Truffle hosted the first annual TruffleCon this weekend in Portland, Oregon. The event brought together developers from around the country to continue to build the community and create connections in the Ethereum developer space,
