Blockchain Supply Chain App for Intelligent Track & Trace by Mary Hall

image

Blockchain technology offers  greater transparency and a single source of truth for for participants using supply chain networks. Intelligent track and trace of orders, goods and delays via blockchain could expedite the sending and receipt of goods.

Today’s supply chains produce multiple data points often times resulting in thousands of daily transactions that need to be validated and confirmed.

While all this "big data" data presents opportunities, it can also be incredibly difficult to manage, especially if that data isn’t properly validated by all parties. The lack of validation can expose organizations to risk, especially if they are trying to track supply chain goods that are regulated by law.   For supply chain tracking, blockchain technology offers some unique benefits.

  • Traceability: Full audit tail of data throughout the supply chain
  • Compliance: Single, timestamped, tamper-proof source of data
  • Flexibility: Real-time rule-based verification of multi-party confirmations
  • Reliable transactions: Trusted digital signature based peer to peer interactions

Intelligent Track and Trace on Blockchain for Supply Chain
Oracle’s Blockchain Supply Chain Application is designed to help organizations meet some of the business problems posed by supply chain networks.

In late 2018, Oracle announced a new suite of Blockchain Applications at Oracle OpenWorld. Since the announcement, Oracle has been closely collaborating with  early adopters to gather their feedback to help design the Blockchain Apps.  At MBX, March 19-21 in Las Vegas, Oracle experts  will share aggregated learnings from their design partner engagements and take a deep dive into our first Blockchain Application Offering: Oracle Intelligent Track and Trace.

Oracle Blockchain Verifies Real Honey by Mary Hall

image

At the recent Oracle OpenWorld Dubai show, Oracle showed a demonstration of how natural Honey can be verified by blockchain.  You may wonder, well, why would anyone need Honey verified by blockchain? You may be surprised to learn that Honey is one of the most frequently impure or mislabeled foods. In recent years, Honey mixed with impure ingredients such as sugar, salt, corn syrup and even toxins has been found at grocery suppliers and retailers.

According to research by Food Safety News, as much as 76% of the Honey sold in grocery stores is fake. Some of it even contains toxins which can make people very ill. With the increase of fake Honey flooding the market, the importance of making the provenance and the origin of Honey transparent to consumers, via labeling powered by blockchain, can not be underestimated.  Putting Honey on the blockchain can literally save people lives by identifying potentially harmful ingredients.  In an article exploring the honey laundering industry, Wide Open Eats identifies that some fake Honey contains, Chloramphenicol, an antibiotic banned in the U.S. that has been linked to cancer and is dangerous to some people.

Oracle BlockChain Service: creating a smart contract aka how to write a chaincode by Lonneke Dikmans

image

In the first blog about blockchain, I used Oracle Compute Cloud Classic and installed MultiChain on it. Since then, Oracle has released a Blockchain Cloud Service with a lot of out of the box functionality, based on Hyperledger.
In this blog post I will describe how to create a smart contract for a webshop use case: getting offers from different suppliers for a specific order. I already know node.js so I will write the ChainCode in node. Note that go is also supported.

Prerequisites
  • A running instance of Oracle Blockchain Service
  • Node.js installed on your laptop

There are a number of steps involved in writing a smart contract (or chaincode).

  1. Design the chaincode
  2. Write a chaincode (in Node)
  3. Deploy a ChainCode to a Peer
  4. Test the chaincode with Postman
Design

Before you write a chaincode, you need to know what transactions need to be supported. In our example we have a webshop, that issues requests for shipping after ordering an item. Shippers can create an offer. If they are selected by the customer, they pickup the shipment. The customer receives the goods at the end of the cycle. For more information about designing the chaincode, see the hyperledger documentation. Read the complete article here

Arab Jordan Investment Bank in Production with Oracle Blockchain by Mary Hall

image

Arab Jordan Investment Bank (AJIB) is now in production with the Oracle Blockchain Platform.  The project is the largest blockchain deployment in the Middle East.   AJIB deployed Oracle Blockchain Platform to replace the banking application previously used for money transfers between AJIB entities, resulting in cost-savings and real-time cross-border transactions.

Results before and after using blockchain technology

Before using blockchain, money transfers between Arab Jordan Investment Bank (AJIB)  subsidiaries were achieved by using third-party intermediaries.  These intermediaries charged fees at each stage of a cross-border transfer transaction.   In addition to the additional fees, using theses intermediaries made it necessary for the bank to  share some customer information with third parties.  Sharing this type of information involved compliance with strict regulatory requirements. AJIB aimed at reducing the costs and the time required for cross-border payments, while making the entire process more secure and efficient.

With Oracle Blockchain, AJIB is now able to make the same transfers in real-time without paying the transactions fees for each transaction to third party intermediaries. Senders and receivers can now  track money transfers while the funds are in transit, providing transparency to both parties about the exact timing and amount of the transfer.

Five Ways Blockchain Is Changing Higher Ed
For one, blockchain’s ability to manage, share, and protect digital content makes it ideal for helping researchers and educators create intellectual property, share it, and still control the way it’s used. Professors, for instance, could be rewarded based on the actual use, and reuse, of their teaching materials, much as how they’re rewarded based on citations in research papers and journals. Four more advantages.

Another blockchain: installing Ethereum on Oracle Cloud by Lonneke Dikmans

image

After installing MultiChain on Oracle Compute Cloud, and playing around with HyperLedger on the Oracle Blockchain Cloud service, I now ran into a case where Ethereum was used.
This blog post describes how I installed a Ethereum node on Oracle Cloud Infrastructure.

Prerequisites
  • An account on Oracle Cloud with Administrator rights
  • You have generated an ssh key-pair
  • You are logged in to your cloud account
Create Compartment

Create a compartment with the name Ethereum to separate this from your other infrastructure. You can find this under "Identity".

Create a Virtual Cloud Network
  1. Navigate to Virtual Cloud Network, by selecting Network from the Menu
  2. Select the compartment you just created
  3. Click "Create Virtual Cloud Network"
  • The compartment will default to the compartment you just selected
  • Name: ethereum-network
  • select "Create Virtual Cloud Network plus related resources" to quickly get up and running
  • Click "Create"

A dialog is displayed that shows you what has been created, after a few seconds.

Create compute nodes

For this example I will create 3 nodes on 3 separate VMs. Read the complete article here.

Integration and Blockchain – Heart of the Digital Economy by Steve Quan

image

Digital transformation is inevitable if you are looking to thrive in today’s economy.  In the first three podcasts of the series “Integration: Heart of the Digital Economy,” we heard about how application and data integration play a central role in business digital transformations.

In this new podcast, you’ll learn how the combination of Blockchain technologies, APIs, application and data integration extend enterprise backend systems for B2B or B2C business models.  Blockchains are a series of secured transactions between two parties called a block.  These blocks are linked together and used as a distributed ledger to store any information used in a business transaction. So as your company starts to develop blockchain specific applications, you’ll need to carefully plan and link your blockchain strategy with your integration strategy. This ensures that you can push (and pull) corporate data into (or from) their Blockchains.

Learn how different industries use Blockchain technology.  Listen to the podcast  Blockchain Integration: Powering the Smart Economy.

At GE Digital, Hackfest Chases Big Ideas

image

“We do hackathons a bit differently,” explains GE Digital’s Kamil Litman. “Instead of use cases being fed to the teams, we want part of it to be the ideation phase.” Not long ago, the company created a way to give energy buyers real-time pricing insights at GE oil and gas subsidiary Baker Hughes. Also helpful: Oracle demonstrated how other teams have used cloud technologies for their own projects. What came out of the three-day hackathon
