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.
Mobile devices also have sensors such as GPS and cameras that can add complementary data that can help attest to the what, where, and when of deliveries.
These systems also become clients via extension and need to interact with smart contracts to provide and receive attestable data on behalf of an organization. Bots and assistants enable manufacturers and retailers to interact with the supply chain. As a best practice, indicate the version of Solidity you are targeting. Specifying the version helps avoid incompatibilities with future Solidity versions. Add the following version pragma at the top of HelloBlockchain. Blockchain Workbench uses the configuration file and smart contract code file to create a blockchain application.
There is a relationship between what is defined in the configuration and the code in the smart contract. Contract details, functions, parameters, and types are required to match to create the application. Blockchain Workbench verifies the files prior to application creation. Add the contract header to your HelloBlockchain. State variables store values of the state for each contract instance.
The state variables in your contract must match the workflow properties defined in the configuration file. Add the state variables to your contract in your HelloBlockchain.
The constructor defines input parameters for a new smart contract instance of a workflow. Required parameters for the constructor are defined as constructor parameters in the configuration file. The number, order, and type of parameters must match in both files.
In the constructor function, write any business logic you want to perform prior to creating the contract. For example, initialize the state variables with starting values. Add the constructor function to your contract in your HelloBlockchain. Functions are the executable units of business logic within a contract. Required parameters for the function are defined as function parameters in the configuration file. Functions are associated to transitions in a Blockchain Workbench workflow in the configuration file.
A transition is an action performed to move to the next stage of an application's workflow as determined by the contract. Write any business logic you want to perform in the function. For example, modifying a state variable's value. Add the following functions to your contract in your HelloBlockchain. To add a blockchain application to Blockchain Workbench, you upload the configuration and smart contract files to define the application.
Deployment of the blockchain application takes a few minutes. When deployment is finished, the new application is displayed in Applications. Add application members to your application to initiate and take actions on contracts. To add application members, you need to be a Blockchain Workbench administrator.

Tutorial: Create, build, and deploy smart contracts on Azure Blockchain Service
As a business, you do not have to manage the ledger. Also, there is no cost associated with the ledger itself. However, you need to pay for the app development and its cost when it runs on the Blockchain. You will get virtual machines and the associated infrastructure by allocating the required resources and time.
The blockchain network supports open-source tools. That means you can continue developing your application using the platform and open-source tools. Once done, you can deploy your application over the blockchain network. Azure Blockchain Services comes with the support of four prominent Azure blockchain frameworks, including the Quorum, Ethereum, Corda, and Hyperledger Fabric.
These frameworks are also not limited, as Azure Blockchain will surely add support for other ledger protocols in the future. Azure manages all the backend tools and infrastructure for managing the blockchain network.

Other than that, it is also accessible to provisioning validator and transaction nodes. Moreover, you can also manage the security and the storage of Azure Virtual Networks. As a developer, you can easily configure and create a consortium blockchain infrastructure. All the transaction and validator nodes are protected using firewall rules. As the owner, you need to configure the firewall before you can access them.
Also, data encryption is provided for all the transaction nodes. It is done via TLS. On top of it, you can also add basic authentication, add more firewall rules, or even add access keys. You will also be amazed that Microsoft is very serious about security and has already invested USD1 billion annually.
They also have employed security experts who ensure data privacy. Lastly, they also have more certifications compared to other cloud providers validating their security aspect. The nodes are also maintained to ensure that they run with the latest version of the Blockchain. Azure BaaS is a managed service, and hence everything is managed by the Azure themselves. The consortium blockchain management is baked within the Azure Blockchain.
With it, you get full access to the consortia. You also get full node management and the ability to add or remove members. Other key features supported by the consortium management include simplified policy enforcement and codeless permissioning. Azure Blockchain WorkBench is a free tool provided by Microsoft which lets you manage Azure blockchain applications.
