The App Builder brings speed and business agility to chaincode development, and enables innovation by making blockchain and smart contract accessible to broader development community without requiring specialised skill sets. It also ensures that chaincodes follow best practices by auto generating the core Create, Read (Query), Update and Delete (so called CRUD methods)…

Faster, Easier Development of Smart Contracts is Here Today with Blockchain App Builder for …

In my last post I showed how to create, run, and test a smart contract using the Blockchain App Builder. In this post I’ll cover how we can take the newly developed smart contract and deploy and test it with an instance of the Oracle Blockchain Platform. The major difference between running and testing a smart contract in the Oracle Blockchain Platform cloud service versus running it locally is that we can’t use things like nodemon to automatically restart and reload the chaincode container. Running locally, we use Docker to spin up the various Hyperledger Fabric components on the local…

Faster, Easier Development of Smart Contracts is Here Today with Blockchain App Builder for …

In my last post I introduced the Oracle Blockchain App Builder and some of its features. In this post I’ll dig into more detail about the specification file that is used to drive the development of the smart contract and how the resulting chaincode can be tested in minutes. The specification file is the heart of the application to be built on the Oracle Blockchain Platform. It defines the assets/objects to be managed by the smart contract and the behaviors/functions associated with each of those assets. While the example used only shows a single asset, a car, a specification file…

Oracle Blockchain Platform adds the Raft Consensus Algorithm

One new major feature in the recent release of the Oracle Blockchain Platform is the enhanced consensus protocol with a new Raft algorithm. With this new type of consensus, blockchain users can manage larger sized networks compared with the previous version, while also improving data privacy and governance capability. So why does consensus protocol mean so much to a blockchain network? And why did the Oracle Blockchain Platform decided to adopt the Raft consensus protocol, and what benefits will the customers gain with the new feature? This blog will reveal all the secrets underneath and respond to these questions. Why is consensus…

You Too Can Quickly Build a Blockchain POC Using Pre-assembled Oracle Cloud Tools

You might've seen the presentation on Modernizing Intercompany Billing Using a Permissioned Blockchain Platform [PAN6441] from the last OOW, or more recent versions at Analytics and Data Summit in February (pdf) or ODTUG "Learn from Home" Series, which took place last week. The implementation of this Intercompany billing and reconciliation use case produced very sophisticated set of capabilities for managing this challenging Intercompany process using distributed ledger based on Oracle blockchain technology and related cloud services.  Looking at the results you might've wondered how difficult would it be to implement a blockchain application that integrates with ERPs, Analytics, and role-based Security.  Would…
