This Visual Studio Code extension for Azure Blockchain provides developers an enhanced experience for building Blockchain apps utilizing Azure Blockchain Service, or even the public Ethereum network. It also enables you to utilize popular, open source Blockchain tools such as Solidity and Truffle. Sure, there have been Solidity and other Blockchain technology extensions for Visual Studio Code published by others in the community, however now there is also an official set of tools published by Microsoft.
This proves even further the investment and dedication that Microsoft is putting forth towards the use of Blockchain ledger technologies in the Enterprise, or even on the public blockchain networks. While there are some great command line tools e. Native integration of the Truffle Debugger into Visual Studio Code brings all the standard debugging features developers have come to rely on e. This allows developers to interact with their deployed contracts, directly in the IDE environment without having to build other UI or custom software simply to test out basic functionality of their contracts.
Having a simple, graphical user interface GUI driven interface that allows developers to interact and test out basic functionality of their contracts inside the IDE, without writing code, is a huge improvement in productivity.
For rapid development of smart contracts, having the ability deploy contracts to a blockchain quickly to test and debug is a key principle. The extension has integrated Ganache directly into the IDE to further lower the bar to entry, and allow even faster development iteration. By default, there is nothing to configure, and the following steps can be used. After selecting to deploy the contracts, either from the Command Pallette or by right clicking on the contract and selecting Deploy contracts, a dropdown will be presented with options for where to deploy the contract.
By default there will be a single entry on this list named development. After selecting development, the IDE will create a new instance of Truffle Ganache, which will use the default configuration for the project as the target. The IDE will then deploy the contracts to this instance.
If there is a need to run the Ganache instance on a port other than the default of , a new Local Network can be created and the port configuration added for this. The steps do this are:. If you are a developer that would like to target public testnet and mainnet for Ethereum, the ability to leverage Infura from inside the IDE is provided via this extension.
For those that aren't familiar with Infura, it provides the tools and infrastructure that allow developers to easily take their blockchain application from testing to scaled deployment - with simple, reliable access to Ethereum mainnet and testnets, and also has support for IPFS. Details can be found on the Getting started with Infura blog and on the Infura Docs pages.
To use Infura, the first step is to either create or connect to an existing Infura project. The IDE will step through this process. At this point the extension will prompt you for credentials to sign into Infura. Simply click the sign in button. Don't worry if you don't already have an Infura account, because you can create one if needed. On the Infura login page, login with your Infura account credentials.
If you don't already have an Infura account, simply click the Sign Up link at the bottom. After signing into Infura, you will be askted for authorization to share your Infura projects with the extension. Click Authorize. Next close the browser window and you will back in the IDE. A prompt will be presented to allow you to enter a project name.
Enter the desired name for this. Next select the availability of the project inside Infura public or private. By default, public is the option used.
After a few seconds, the Blockchain view will show a new Infura Service, with your project nested under, and under this will the various endpoints that Infura provides. Now that a connection to Infura has been created, this network can easily be targeted when deploying contracts.
When right clicking and deploying contracts, a set of options will be added for these new Infura destinations. Simply select the desired target network endpoint and the extension will deploy the contracts to this location.
Hyperledger Besu is a popular Ethereum client that is unique in that it offers a client that can be used in either public networks, such as Ethereum mainnet or private, consortium based networks. It can be deployed a variety of ways , and recently a preview has been made available in Azure. Currently, the Hyperledger Besu is fully compatible with the extension, however the provisioning of the nodes is not yet fully integrated.
To connect to a running Besu node with the extension, you can do the following:. This varies based on the deployment model, for Azure deployments these can be retrieved from the output parameters from the deployment.
Update the configuration manually. This is shown in the video below. The extension has the ability to use an HD Wallet provider that simply requires a file with a mnemonic to function. If you are a developer that would like to target a network that leverages Azure, this option is also available. The option to create new networks or connect to existing ones are is available, the same as with Infura and Local networks!
Enter the name of your Consortium. Wait until your resource has been created in Azure. Note: Deploying the Azure Blockchain Service takes quite some time to complete. Please check the deployment status in the Azure portal. Our Wiki page includes a comprehensive getting started guide with detailed usage instructions for this plugin.
Those hashes are then placed on a public or private chain. If the hashes match, the document is authentic, but if so much as a pixel of an image or letter in a document is changed, the hashes will not match and this will make obvious that tampering has occurred.
Also included are smart contracts for files and a file registry to store the hashes on chain. Smart Contract Interaction: Getting blockchain off the whiteboard and into production means dealing with the realities of how counterparties interact today. That reality is that Enterprise integration is messy. Microsoft brings our decades of experience in this area to blockchain.
Our work with integrating Enterprise systems began almost two decades ago with the introduction of BizTalk server, and our focus on database integration traces back to our co-development of Open Database Connectivity ODBC in the s. All of our experience has been captured and made available in Azure services.
The Blockchain Application Development Kit includes Workbench integration samples in the following areas:. Today, we are also announcing that we will release a set of Logic App and Flow Connectors to extend these samples to ledgers like Ethereum , Corda , Bitcoin, and others. Blockchain is moving out of the labs and into everyday business applications.
The Ethereum blockchain connector is available today and enables users to deploy contracts, call contract actions, read contract state and trigger other Logic Apps based on events from the ledger. With the mainstreaming of blockchain technology in enterprise software development, organizations are asking for guidance on how to deliver DevOps for smart contracts and blockchain projects.
While there are some nuances to the approach, the good news is that just like other types of solution development, this model can readily be addressed in a DevOps model. The Azure Blockchain Development Kit is the next step in our journey to make developing end to end blockchain applications accessible, fast, and affordable to anyone with an idea.
It is built atop our investments in blockchain and connects to the compute, data, messaging, and integration services available in both Azure and the broader Microsoft Cloud to provide a robust palette for a developer to realize their vision.
Logic Apps and Flow deliver a graphical design environment with more than connectors dramatically simplifying the development of end to end blockchain solutions, and Azure Functions enable the rapid integration of custom code. A serverless approach also reduces costs and management overhead. With no VMs to manage, built-in scalability, and an approachable pricing model the Azure Blockchain Development Kit is within reach of every developer — from enthusiasts to ISVs to enterprises.
Solutions are written using online visual workflow designers and Visual Studio Code , a free download that provides an integrated development environment on Windows, Mac, and Linux. The resulting applications will run atop a network that has higher rated cloud performance than other large-scale providers and enable federating identities between participants using Azure Active Directory. With Azure, those applications can be deployed to more regions than any other cloud provider and benefit from more certifications.
To learn more about how to use these samples to build and extend blockchain applications, you can find a host of videos on our Channel 9 show Block Talk. Blog Announcements. Introducing the Azure Blockchain Development Kit. Connect To deliver end to end blockchain solutions for consortiums, developers need to enable organizations, people, and devices to connect to the blockchain and do it from a heterogenous set of user interfaces.
Take for example an end to end supply chain for a commodity such as cocoa. SMS and voice interfaces enable small hold farmers in Africa to transact and track their goods at the first mile of the supply chain.
Internet of Things IoT devices deliver sensor data to track the conditions of the goods at different points in their journey to market — tracking the humidity in the containers where the beans are held to the temperature of the end product of ice cream that it is incorporated into. Mobile clients enable logistics providers to accept and transfer responsibility for products on their journey from manufacturer to retail using the compute power that already exists in the pockets of its employees.
