Blockchain of Oracle

As the solution of the blockchain platform based on Hyperledger Fabric are

services such as enhanced node provisioning, blockchain explorer, and

improved security.

Blockchain workflow application

To digitize workflows such as moving physical assets across supply chains

using blockchain, they share with other organizations. Across use cases, the

anatomy of blockchain apps is similar.

A consortium application is built that can ingest signals from relevant user

interfaces and communicate ledger data to consuming apps across the

consortium; here, they use Azure Blockchain Service as the foundational

managed blockchain network.

Architecture

The architecture includes the data flow steps involved which are explained as

follows:

Data flow

The following steps are involved in the data flow:

1. The relevant apps, devices, and data sources send events or data to a

message broker (Azure Service Bus).

2. The distributed ledger technology (DLT) consumer logic app builds

and signs the transaction sent to the transaction builder after the data is

fetched from the service bus.

3 . Via a ledger-specific logic app connector, the signed transaction gets

routed to Azure Blockchain Service

4. The data is sent to configured destinations from configured transaction

nodes that decode events and properties after the data manager of

blockchain captures the block and transaction data.

5 . The message broker sends the ledger data to consuming business

applications and an off-chain database.

6. The information is analyzed and visualized using tools such as Power BI

by connecting to an off-chain database.
