DLT Labs Turns to Hyperledger Fabric to Resolve Freight Transportation Invoice and Payment Challenges for Walmart Canada

By Blog, Hyperledger Fabric

As part of its commitment to provide the lowest everyday prices for its consumers, Walmart Canada has a sharp focus on supply chain logistics. One vital piece: the freight transportation that ensures Walmart is sufficiently stocked to service more than 1.2 million customers across 400 stores every day. 

Walmart partners with third party transportation companies, referred to as carriers, that work around the clock, and through all seasons, to deliver goods. These carriers are a vital link in Walmart’s supply chain. However, there is a high level of complexity to managing the information flow and invoice payments with the carriers, which is a big deal as shipping is a capital-intensive business with a high degree of cost volatility (fuel prices, delays, unexpected events). 

It is not uncommon to have invoice disputes in the range of 70% or more for every load a carrier delivers (one invoice per load). Despite various service providers trying to solve this puzzle using the full spectrum of existing technologies, disputes continue to plague the industry with high administrative costs and lengthy payment delays, and invoice reconciliation often simply means one side or the other capitulated.

For Walmart, the complexity is multiplied by working with up to 70 different carriers in its supply chain, each of which has its own respective process for calculating shipping costs based on individual contracts that outline varying rates for fuel, line haul and other charges.

Walmart Canada enlisted the help of DLT Labs™, a global leader in the development and deployment of an innovative enterprise-level platform using distributed ledger technology, to develop a solution that would solve the perennial dispute problem once and for all.

In early 2019, DLT Labs rolled out the world’s largest full production blockchain solution for any industrial application: DL Freight™. Remarkably, because the platform is fully configurable, DL Freight was configured for the demanding needs of Walmart in just 60 days. The new system tracks deliveries, verifies transactions, and automates invoices in real time. Reconciliation between Walmart and its fleet of carriers is no longer even necessary because they are all working off the same information and calculations by way of smart contracts.

DL Freight is built on Hyperledger Fabric, an open source platform that allows Walmart to bring together all the carriers within its multi-partner freight operations under one architecture to automate and implement universal workflows across the network. At the same time, through Hyperledger Fabric’s unique “channels” feature, the solution allows independent and protected relationships for each organization directly between itself and Walmart, and the information is not accessible to other members.

Within DL Freight, carriers are the peers, and the governance of the platform is controlled by the applicable contracts, as in any conventional business. The difference is that the freight, legal, and finance departments of Walmart, as well as all the carriers, have all agreed that the solution fairly and accurately represents those agreements so it processes them automatically. As a result, it has removed the guesswork and any real potential for dispute over the interpretation of agreements. 

Hyperledger teamed up with DLT Labs and Walmart Canada on a case study about the creation and adoption of DL Freight, the national standard for freight invoice management for Walmart Canada and its national network of carriers. It delves into key design decisions and outcomes as well as security safeguards and the roadmap for DL Freight as an industry platform.

Developer Showcase Series: Sushma Varadaiah, Coding Bootcamps

By Blog, Developer Showcase, Hyperledger Fabric

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Sushma Varadaiah from Coding Bootcamps.

What advice would you offer other technologists or developers interested in getting started working on blockchain?

I personally feel that it’s the right time to get into blockchain as it holds a lot of potential in the very near future. Blockchain will be the way that we are going to establish trust and transparency in the world as we move forward. Along with other technologies like Artificial Intelligence and Internet of Things, the use of blockchain multiply.

Give a bit of background on what you’re working on, and let us know what was it that made you want to get into blockchain?

I have 6+ years of experience as a software developer. I am currently working on blockchain systems (Ethereum and Hyperledger Fabric). I got into blockchain because I studied cryptography and security while getting a Master degree in Computer Science and Information Security. It was easy for me to pick up blockchain’s underlying technologies because of my Master’s studies. I recognized the technology’s potential and got into blockchain.

What project in Hyperledger are you working on? Any new developments to share? Can you sum up your experience with Hyperledger?

I am working on Hyperledger Fabric. My journey with Hyperledger Fabric started when I got my first blockchain certification from the Linux Foundation followed by a Master’s degree certification in blockchain from International Institute of Information Technology Bangalore. I have developed Hyperledger Fabric Proofs of Concept for a range of use cases including  pharmaceutical drug supply chain, certificate verification and property registration network. You can find source code for all these in my GitHub page.

What are the main differences between teaching Hyperledger to students and developing Hyperledger applications?

While teaching at Coding Bootcamps, the main challenge is to explain blockchain concepts to a student who is new to the technology. Troubleshooting the issues that are faced by students who are learning to develop blockchain applications is a very rewarding feeling. On the other hand, developing Hyperledger applications for a business involves different complexities like deploying and scaling the application according to user growth.

What do you think is most important for Hyperledger to focus on in the next year?

Devtools for easy smart contract development and deployment.

As Hyperledger’s incubated projects start maturing and hit 1.0s and beyond, what are the most interesting technologies, apps, or use cases coming out as a result from your perspective?

I personally feel Hyperledger Fabric has a lot of potential to bring transparency to supply chain management use cases. 

What’s the one issue or problem you hope blockchain can solve?

Increasing transparency and trust among users.

Where do you hope to see Hyperledger and/or blockchain in five years?

I hope to see applications moving towards decentralization and industry maturing towards adoption of blockchain with other technologies like Artificial Intelligence and the Internet of Things.

What is the best piece of developer advice you’ve ever received?

Never stop learning.

What technology could you not live without?

Internet!

How AAIS Aligned Insurers and Regulators with the Hyperledger Fabric-Based openIDL Data Reporting Network

By Blog, Hyperledger Fabric

Since 1980, the United States has suffered more than 250 extreme weather disasters causing more than $1 billion damage each. Every time a natural catastrophe strikes, state regulators quickly ask insurance carriers to send them data about the affected properties. This data helps regulators model risk, monitor market activity, protect consumers, and plan for future emergencies.

These ad-hoc reports come on top of routine quarterly and annual statistics that insurance carriers must provide to regulators. But the reporting process was flawed. Insurers could barely keep up with the requests for data, in various formats and often with short deadlines, coming in from 50 different state regulators. 

As a national, not-for-profit member association that gathers, aggregates and anonymizes data from its property and casualty (P&C) insurance industry members to inform legislative policy, Chicago-based American Association of Insurance Services (AAIS) saw the reporting problems first hand. In fact, everyone in the industry saw the need for a more resilient and efficient resource: a system that would yield data to inform policymakers and also help carriers operate efficiently and the platform to compete and innovate in the marketplace.

AAIS invited carriers and regulators to brainstorm a solution they could build and deploy to address the industry’s data problem. As discussions progressed, the group raised the idea of using blockchain. And, to address the cost concerns, using open source software. By starting with an existing open source framework, AAIS wouldn’t have to code a blockchain platform from scratch. The team could get on with building the higher-level components and interfaces for their system, which they named the Open Insurance Data Link (openIDL).

That led to the choice of Hyperledger Fabric. After AAIS picked a blockchain platform, it needed a development partner with all the skills and resources to bring openIDL to life. The team decided to partner with IBM because of the organization’s track record with Hyperledger Fabric and their expert team. With shared philosophies that included design thinking and agile development, AAIS and IBM developed and tested a prototype in record time. With the first prototype, they were able to test five million records in less than 90 days.

In 2018, openIDL went into production as the first blockchain network connecting data across the American insurance industry. Insurers have the option to manage their own node or use the multi-tenant environment managed by AAIS. And, to help insurers spin up their own nodes, IBM created openIDL in a Box: a managed service offering everything an insurer needs to join the blockchain network.

Hyperledger worked with AAIS to document key steps in engaging stakeholders in planning openIDL and building a network that ensures data privacy for insurers and reporting for regulators. Read the full case study here for more on the design process, solution architecture and next steps for openIDL.

#HyperledgerFinTech: A sampling of production applications using Hyperledger technologies in the finance market

By Blog, Finance, Hyperledger Besu, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha

The financial services market has long turned to technology to address a range of back-end challenges and enhance customer-facing services. Blockchain is increasingly becoming a go-to technology for advancing many different financial systems and solutions with different Hyperledger platforms serving as the core for an array of applications now in production. 

Read on for just a sampling #HyperledgerFinTech solutions, built using a mix of Hyperledger technologies:

Bakong

Sponsored by the National Bank of Cambodia, the country’s central bank, Bakong is the first retail payments system in the world using blockchain technology. Built on Hyperledger Iroha, Bakong delivers value for customers, merchants and banks. Individuals can now transfer money and buy from merchants with a simple smartphone app. Merchants gain a fast, cashless, and secure payments system. And banks can do interbank transfers at much lower cost.

Bakong was developed by Soramitsu and, after a soft launch in 2019, is now expanding with 16 financial institutions using the system and more expected to join in the near future. The project was also designed to promote financial inclusion for the country’s large number of unbanked citizens. Any citizen of the country can open a Bakong account, even if they don’t have a traditional bank account. The more than 500 merchants that accept Bakong can be viewed in a map inside the app. 

daura 

Built atop the private Swiss Trust Chain run by Swisscom and Swiss Post and powered by Hyperledger Fabric, daura is a digital share platform for financing and investing in Swiss SMEs. With daura, the share register is easily digitized and capital increases are carried out quickly and inexpensively at the push of a button. Shares can be split into any number of small lots and the share register is always digitally maintained, complete and up-to-date. With daura, companies have also transitioned virtual Annual General Meetings as a response to COVID-19 with authorization and access are granted directly via the blockchain. 

ioCash

ioBuilders is a blockchain technology company focused on building regulated fintech and enterprise solutions based on distributed ledger technology to help businesses succeed in their blockchain adoption. The company offers professional services, including technical, business and regulatory, and develops its own product line. ioBuilders has been one of the first adopters and advocates of Hyperledger Besu, providing essential feedback to improve its enterprise requirements capabilities. 

ioCash, one of ioBuilder’s core products, is a fintech platform enabling the use of regulated fiat money on blockchain networks, making it programmable with smart contracts and able to interact with other blockchain use cases. ioCash’s platform operates under an electronic money licence, providing accounts (with or without IBAN) and complex payments functionalities through API and smart contracts connectivity. ioCash is also available as a technology license for financial institutions that hold banking or electronic money licences and are aiming to add the benefits of blockchain into their payment systems. 

Memberpass

CULedger, a credit union service organization (CUSO) that began when a group of credit unions came together in 2016 as a direct response to the increasing threat of fraud, set out to bring a decentralized identity solution product for credit unions to market. The result was MemberPass, a permanent, portable digital identity credential for credit union members.

Built in partnership with Evernym and using Hyperledger Indy, Memberpass replaces vulnerable authentication processes such as common knowledge-based questions. Now credit unions are able to issue a digital credential to members, giving them a hassle-free way to control and prove their identity quickly and easily while protecting their personal information.

Answering the FDA’s call: LedgerDomain’s Hyperledger Fabric-based BRUINchain improves tracking and tracing of prescription drugs

By Blog, Healthcare, Hyperledger Fabric

Four billion prescriptions were dispensed at US pharmacies in 2019, and even conservative estimates suggest that over 100 million prescriptions may be incorrectly dispensed. To address this problem, healthcare leaders are actively working to put new tools into the hands of pharmacists to ensure the right drugs reach the right people.

Part of that effort is the Drug Supply Chain Security Act (DSCSA), an ongoing, decade-long effort to track and trace prescription drugs in the United States. The DSCSA is intended to enhance the FDA’s ability to help protect consumers from drugs that may be counterfeit, stolen, contaminated, or otherwise harmful. The vision is to have an interoperable system in place by 2023 that will allow for drug tracing, product verification, and prompt detection and response protocols to handle all suspect medications. To get the system in place, the FDA turned to the public in 2019 and asked for new, cutting-edge approaches to improve the prescription pipeline.

LedgerDomain, an enterprise-grade blockchain solutions provider known for its work on developing the next generation of healthcare and pharmaceutical supply chains, was one of the companies that responded to the FDA’s request. LedgerDomain’s proposal of a blockchain-based solution in collaboration with UCLA and the pharmaceutical company Biogen was selected by the FDA as part of its pilot project program. 

LedgerDomain’s pilot centered on the development and live testing of BRUINchain, a blockchain-based system that meets DSCSA standards for pharmaceutical dispensers all within a shared-permission yet private ecosystem. While the pharmaceutical supply chain has numerous stakeholders, BRUINChain, which is built on Hyperledger Fabric, establishes one version of the truth for the pipeline that is immutable and invaluable.

The team tested BRUINchain within UCLA Health’s network of 500 pharmacists and technicians, focused on tracking the drug Spinraza, the first medication approved to treat children and adults with a rare and often fatal genetic disease called spinal muscular atrophy. The results exceeded UCLA Health and LedgerDomain’s expectations. The BRUINchain app’s barcode scanning functionality on iPhones was 100 percent effective, and the Hyperledger Fabric-based system was able to track every dose of Spinraza at UCLA Health, down to which refrigerator each dose was stored in across the campus. Even before the pilot ended, the team was adding new functionality and products as the network of pharmacists grew more reliant on the BRUINchain system. 

Hyperledger teamed up with LedgerDomain on a detailed case study on the BRUINchain pilot, including deployment details and results, projected cost and time saving and next steps based on the solution’s success to date.
