Blockchain

Develop, test, and deploy secure blockchain apps

What is a blockchain?

Blockchain is a transparent and verifiable system which will change the way people think about exchanging value and assets, enforcing contracts, and sharing data. The technology is a shared, secure ledger of transactions distributed among a network of computers, rather than resting with a single provider. Businesses are using blockchain as a common data layer to enable a new class of applications. Now, business processes and data can be shared across multiple organizations, which eliminates waste, reduces the risk of fraud, and creates new revenue streams.

How Blockchain will Accelerate Business Performance and Power the Smart Economy

“When fully automated, blockchain can enforce consistency in execution, assist with dispute resolution, increase accountability, and deliver end-to-end transparency that can inform better business decisions.”

Blockchain workflow application

Overview

Businesses use blockchain to digitise workflows they share with other organisations, such as moving physical assets across supply chains. The anatomy of blockchain apps is similar across use cases. Here, we use Azure Blockchain Service as the foundational managed blockchain network and build a consortium application that can ingest signals from relevant user interfaces and communicate ledger data to consuming apps across the consortium.

Flow

  1. 1 Relevant apps, devices and data sources send events or data to a message broker (Azure Service Bus).
  2. 2 The distributed ledger technology (DLT) consumer Logic App fetches the data from the Service Bus and sends to transaction builder which builds and signs the transaction.
  3. 3 The signed transaction gets routed to Azure Blockchain Service (fully managed Ethereum consortium network) via a ledger-specific Logic App connector.
  4. 4 The blockchain data manager captures block and transaction data from configured transaction nodes, decodes events and properties and then sends the data to configured destinations.
  5. 5 Message broker sends ledger data to consuming business applications and off-chain database.
  6. 6 Information is analysed and visualised using tools such as Power BI by connecting to off-chain database.

Supply Chain Track and Trace

Overview

A common blockchain pattern is IoT-enabled monitoring of an asset as it moves along a multi-party supply chain. A great example of this pattern is the refrigerated transportation of perishable goods like food or pharmaceuticals where certain compliance rules must be met throughout the duration of the transportation process. In this scenario, an initiating counterparty (such as a retailer) specifies contractual conditions, such as a required humidity and temperature range, that the custodians on the supply chain must adhere to. At any point, if the device takes a temperature or humidity measurement that is out of range, the smart contract state will be updated to indicate that it is out of compliance, recording a transaction on the blockchain and triggering remediating events downstream.

Flow

  1. 1 IoT devices communicate with IoT Hub. IoT Hub as a route configured that will send specific messages to a Service Bus associated with that route. The message is still in the native format for the device and needs to be translated to the format used by Azure Blockchain Workbench. An Azure Logic App performs that transformation. It is triggered when a new message is added to the Service Bus associated with the IoT hub, it then transforms the message and delivers it to the Service Bus used to deliver messages to Azure Blockchain workbench. The first service bus effectively serves as an "Outbox" for IoT Hub and the second one serves as an "Inbox" for Azure Blockchain Workbench.
  2. 2 DLT Consumer fetches the data from the message broker (Service Bus) and sends data to Transaction Builder - Signer.
  3. 3 Transaction Builder builds and signs the transaction.
  4. 4 The signed transaction gets routed to the Blockchain (Private Ethereum Consortium Network).
  5. 5 DLT Watcher gets confirmation of the transaction commitment to the Blockchain and sends the confirmation to the message broker (Service Bus).
  6. 6 DB consumers send confirmed blockchain transactions to off-chain databases (Azure SQL Database).
  7. 7 Information analysed and visualised using tools such as Power BI by connecting to off-chain database (Azure SQL Database).
  8. 8 Events from the ledger are delivered to Event Grid and Service Bus for use by downstream consumers. Examples of "downstream consumers" include logic apps, functions or other code that is designed to take action on the events. For example, an Azure Function could receive an event and then place that in a datastore such as SQL Server.
