An application's workflow can involve properties, functions, and states required describe the flow of a contract. Smart contracts represent the business logic of the blockchain application. Currently, Blockchain Workbench supports Ethereum for the blockchain ledger.
Ethereum uses Solidity as its programming language for writing self-enforcing business logic for smart contracts. Smart contracts in Solidity are similar to classes in object-oriented languages.
Each contract contains state and functions to implement stages and actions of the smart contract. 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.
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. This includes interacting with smart contracts for orders and provenance using natural language and using attestable data from the blockchain to direct actions taken on behalf of a user.
Integrate Businesses are using blockchain and smart contracts to facilitate multi-party processes. Specifically, there are two areas of integration where guidance is most needed: Documents and Media: Documents and media do not belong on chain, but business processes often involve images, videos, audio, Office documents, CAD files for 3D printers or other file types.
The Blockchain Application Development Kit includes Workbench integration samples in the following areas: Legacy applications and protocols — Sending and receiving files via FTP, processing comma separated files and email delivery of data. Registries — An accelerator that generates a custom registry and registry item smart contracts to accommodate any scenario. Logic App Connectors for Blockchain 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.
Deploy 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.
Common questions include: My business logic and data schema for that logic is reflected in smart contracts. What tools can I use to develop those in? How do I do unit testing and debugging on smart contracts? Many blockchain scenarios reflect multi-party transactions and business workflows. These workflows include signed transactions from multiple parties happening in specific sequences.
How do I think about data for test environments in that context? Smart contracts are deployed to the blockchain, which is immutable. Blockchain is a data technology shared across multiple organizations in a consortium, what are the impacts on source code control, build and release pipelines in a global, multi-party environment?
