#HyperledgerSocialImpact: Highlighting Hyperledger-powered solutions driving change

By Hyperledger Blog, Hyperledger Fabric, Hyperledger Iroha

There’s no better time of year to reflect on the power of technology to improve lives so we are celebrating #HyperledgerSocialImpact month. Organizations of all sizes and types are levering Hyperledger technologies to power solutions that are driving real change. The impact ranges from boosting financial inclusion to tackling climate change and sustainable and equitable business practices to increasing access to healthcare, education and more

Read on for just a sampling of the solutions powered by Hyperledger technologies that at work for the greater good. 

Bakong (and beyond): CBDC payment data for credit underwriting in emerging economies

Access to credit is crucial for micro-, small-, and medium-sized enterprises (MSMEs) to share in growth, especially in emerging economies. However, they often lack the records needed to verify creditworthiness. Hyperledger contributor SORAMITSU has learned firsthand the challenges faced by emerging-market MSMEs and lending institutions alike through its work on Bakong, the National Bank of Cambodia’s blockchain-based digital currency and payment infrastructure.

As a finalist in the Monetary Authority of Singapore’s Global CBDC Challenge, SORAMITSU designed an app capable of querying payment data relevant to credit underwriting. The app is designed for Bakong—which is built using Hyperledger Iroha—but could overlay any DLT-based payment system. Lenders could use the app to query data that are relevant to a given wallet’s creditworthiness, such as payments volume, regularity and geographical area of incoming and outgoing payments, and monthly average balance. Importantly, the app only allows queries to be designed in Boolean (true/false) format, and requires approval (a cryptographic signature) from the wallet being queried. By allowing lenders to query wallets under strict conditions of data minimization and informed consent, the application enables accurate underwriting, while mitigating the risk of data monopolization and threats to privacy. SORAMITSU will draw on the lessons learned in the MAS Challenge throughout its work on CBDC apps and functions targeting social impact worldwide—including in its new cooperation with the central bank of Laos.

Circulor: Transparency for conflict and critical minerals sourcing in the electronics and electric vehicle supply chain

Demand for raw materials such as cobalt, tantalum, and tungsten, which are critical to electronics and electric vehicle battery manufacturing, grows exponentially. Large quantities of these minerals come from Central Africa, where human rights organizations report extremely bad working conditions and cases of child labor. In 2014, UNICEF reported that there were as many as 40,000 child miners in the Democratic Republic of Congo alone. Amnesty International, meanwhile, reports that the cobalt industry is rampant with illegal and unethical practices. This results in increased pressure on manufacturers to ensure the ethical sourcing of their raw materials and full visibility into their supply chains. Leveraging Hyperledger Fabric and the Oracle Blockchain Platform, Circulor builds solutions to track minerals provenance and CO2 emissions and also improve efficiency in complex global supply chains. EV manufacturers like Volvo, Polestar, Mercedes-Benz and others who’ve committed to ethical sourcing utilize Circulor’s solution to track vital information about the authenticity and sourcing of raw materials—from mining and refining to actual use in battery units of the cars rolling off the assembly line.

INDETAIL: Socially conscious projects on the foundation of blockchain networks

INDETAIL, based in the Japanese city of Sapporo, is spearheading the global development of blockchain distributed ledger networks, working with investment-worthy partners on innovative, socially conscious projects. Among INDETAIL’s projects leveraging the Hyperledger Fabric-based Oracle Blockchain Platform are a token-based electric transportation system for seniors; a joint effort with Hokkaido Electric Power on electric vehicle charging stations in rural areas; an automated multilingual smart check-in service “maneKEY” for accommodation facilities; and the Riso Card, a digital wallet that supports online currencies and enables fingerprint identification.

Jyoti – Fair Works: Blockchain tech to help keep “fair fashion” in style

Jyoti – Fair Works is leveraging a Hyperledger Fabric-powered solution to give customers a view into its humanitarian supply chain. From its start, the company has made supply chain transparency part of its fair fashion brand. However, as demand has grown in recent years, Jyoti – Fair Works found its downstream supplier network was difficult to track. To maintain that transparency and to better explain it to the company’s customers, Jyoti – Fair Works has started using a blockchain application built on the Oracle Blockchain Platform by retraced, a participant in the Oracle for Startups program. By mapping its supply chain data—including certified details about the cotton growers, textile manufacturers, fabric dyers, designers, and seamstresses—in retraced’s application, Jyoti – Fair Works can update order, delivery, and production schedules and then create, print, and affix QR codes to both physical and digital garment tags.

KrypC  Environmental Footprint Tracker: Showing consumers each bottles carbon and water footprint

KrypC has partnered with Heineken for a pilot blockchain program to show consumers each bottles’ carbon and water footprint. Imagine finding out the environmental footprint of your beer bottle by just one click! Hyperledger Fabric helped make this realistic by tackling the challenge of realizing full transparency over the hundreds of thousands of farmers in Heineken’s global supply chain. Consumers through this pilot were able to scan their bottle and view its actual journey as well as its environmental impact.

Oceanworks and Keep Sea Blue: Traceability of recycled plastics used in making consumer and industrial goods

Powered by Oracle Blockchain technology based on Hyperledger Fabric, Oceanworks and Keep Sea Blue provide traceability platforms and certifications that are used to encourage effective plastic waste collections from oceans and beaches, linked to sustainable reuse and certification of products made from the recycled materials. Oceanworks uses Oracle’s Intelligent Track & Trace SaaS application, and Keep Sea Blue uses a custom application built directly on the blockchain platform. Both companies have implemented monitoring processes that connect the plastics value chain—collectors, recyclers, manufacturers, brand owners—to track the journey of plastic waste, creating a transparent digital audit trail of the recycled material, and ensuring end-to-end recycled product transparency and traceability.

 Symbridge: Building a market of trust

Envision this: A marketplace where there is trust and transparency. For a free market to operate truly efficiently, transparency is a vital ingredient. Transparency and trust are becoming increasingly important to investors who demand ready access to information, having been taken advantage of too many times or been shocked by headlines that have impacted their portfolio or their expectations for doing business with a company. In an industry like crypto where the market remains highly volatile, regulators are rightfully concerned for the consumer in being able to understand all risks involved.

Symbridge is the first of its kind digital asset exchange looking to change this. Built on the fundamentals of trust, innovation, and transparency, Symbridge combines all the security, efficiency, transparency, and accuracy of a decentralized exchange with the high-frequency and low-latency trading of traditional exchanges. Licensed in the United States, the Symbridge validation network, which was built using Linux Foundation’s Hyperledger Fabric, solves for these issues and helps to build a market of trust. All transactions that have taken place on the blockchain are visible to users of Symbridge’s blockchain explorer, allowing for full auditability. This creates a scenario in which investors can feel confident they are aligned with a company that shares their values and is willing to promote further positive impacts across the industry.

MineHub and KrypC Leverage the Power of Hyperledger Fabric 2.2 to Transform Mining and Metals Supply Chain

By Hyperledger Blog, Hyperledger Fabric, Member Case Study, Supply Chain

Read the full case study here.

Nearly 1.8 trillion USD of metals and minerals move across the world every year from mines, through ports, along transport lines, to processing plants and, ultimately, to the end users. This chain includes hundreds of companies making millions of transactions. Many of these still use manual processes—actual or digital—that require staff resources to process.

MineHub wanted to create a decentralized collaboration platform to solve this problem. The company envisioned a solution that would transform the supply chain workflows and processes for the mining and metals industry. Its solution wouldn’t just improve the practical day-to-day operations. Once in place, this robust, agile platform would help users mitigate damage from unpredictable global disruptions, reduce costs and make more profit due to higher efficiencies and end-to-end visibility of their data.

MineHub was setting out to connect hundreds of companies — from large, international corporations to small, local businesses. Each of these organizations would have unique needs and requirements. To deliver this platform, MineHub realized it needed the power of Private Data Collections (PDCs) that became available with Hyperledger Fabric 2. PDCs deliver critical functionality for bringing together a large group of diverse companies with differing needs and commercial interests and allowing them to exchange business critical data in a secure, private, and scalable manner. They would also need the flexibility to add new organizations and manage them dynamically.

Enter KrypC, a company that understands enterprises that want to work together across interconnected workflows need a single version of truth and that blockchain technology can provide this. From the beginning, KrypC has been focused on leveraging Hyperledger Fabric to build technologies that help enterprises adopt and develop blockchain solutions. The team there was working towards addressing the very challenges MineHub was looking to solve through its Hyperledger Fabric layer 2 platform, KrypCore. After a few discussions, it became clear a partnership between them made sense.

KrypC’s configurable KrypCore platform offers the agility to quickly create and add new functionalities to a decentralized system and to deploy them seamlessly in smart contracts. KrypCore offers a unique and unrivalled approach to performing asynchronous system updates and upgrades amongst a wide variety of users operating on entirely different IT infrastructures. 

With their toolsets, KrypC is able to offer users of decentralized applications a seamless solution to manage security updates and enable rapid addition of new features. By solving for this challenge, MineHub was able to redirect their focus on the user functionality and business value they wanted to unlock for its customers.

Hyperledger Foundation worked with KrypC and Minehub on a case study that details the business and technical challenges of building a platform that connects thousands of companies of diverse sizes without prior relationships and the roles each company plays in the solution. In addition, the case study delves into why and how the release of Hyperledger Fabric 2.2 was key to getting the MineHub to market and what comes next for the supply chain platform.

“While I was already involved in a number of activities in the Hyperledger community, through the Special Interest groups and as a co-organizer of meetup group, I found that the mentorship program can be another venue for a contribution based on the development of a use case related to telecom business management. This project was a good way to explore further the benefits a permissioned blockchain network can offer in automating business processes that require elevated level of trust. Over these few weeks, I am proud of the work performed by Santiago. He showed the capability to grasp different concepts and, through the project, how we could combine the two proposed technologies to solve the problem at hand. As a mentor, I learned about other open source tools in the Hyperledger ecosystem that I was not aware of that provided great value to the proof of concept”

Noureddin Sadawi

“This is a really interesting project and what attracted me the most to it was the fact that it combines blockchain and smart contract technology with natural language processing (NLP) technology. Our mentee, Santiago Figueroa, is an intelligent, hard-working young man who has learned and improved noticeably throughout the course of this project. Santiago has used components from existing previous projects, which highlights the importance of finalising useful projects and making them reusable.

Hyperledger in Action Across Asia

By Hyperledger Blog, Hyperledger Fabric, Hyperledger Sawtooth

It’s #HyperledgerAsia month, so we are spotlighting the fast-growing adoption and deployment of Hyperledger technologies throughout the region. Companies across Asia are driving a nonstop stream of innovative new enterprise blockchain implementations ranging from global shipping networks and international digital health passports to training certification and secure document solutions.

Read on for just a sampling of the solutions at work across Asia powered by Hyperledger technologies. And join the conversation using #HyperledgerAsia on social channels.

BondbloX Bond Exchange

Singapore-based BondEvalue broke through barriers when it unveiled the world’s first blockchain-based bond exchange that allows investors to trade BondbloX Bond Exchange (BBX) – $1,000 fractions of traditional wholesale bonds. This leads to better access and better diversification opportunities for a market that is typically inaccessible except to more wealthy investors.

BBX leverages the Hyperledger Sawtooth blockchain technology to fractionlize bonds, make trading highly transparent and more cost effective. Settlement on BBX is on a T+0 basis, that is within seconds instead of the normal two-day settlement cycle, thereby reducing counterparty settlement risks for investors.

BondEvalue continues to engage more member participants such as Taurus Wealth Advisors, the leading fee-based, multi-family wealth management firm in Singapore, and Amstel, an institutional fixed-income broker with operations across Asia and Europe. BondEvalue is also expanding its footprint with a joint venture partnership in Mexico. The company’s goal is to empower a more diverse pool of investors and introduce them to institutional-grade opportunities in the bond market through its cutting-edge blockchain solution.

Global Shipping Business Network

Global Shipping Business Network (GSBN), headquartered in Hong Kong, is a neutral trade data utility platform whose members include container carriers and terminal operators/ports that handle one in three containers worldwide. It is built on a Hyperledger Fabric-based permissioned blockchain with strong data governance where only authorized parties are granted the right to contribute and consume shipping related data. By leveraging immutability of the blockchain and data field level privacy through cryptography, participants in the supply chain such as terminals, carriers, shippers, freight forwarders, truckers, customs and financial institutions, can collaboratively design and enable industry wide, end to end, solutions. The platform was developed in partnership with Oracle, Microsoft, AntChain and Alibaba Cloud. 

[markets]N 

Developed by KoinEarth and deployed using Hyperledger Fabric on Oracle Blockchain, [markets]N is a secure B2B platform that’s used by India-based Hindalc, the world’s largest aluminum rolling company, to get a higher degree of visibility into its inventory and supply chain and enforce its SLAs with service providers. This includes tracking and monitoring of purchasing orders, shipments and invoices in real-time, in coordination with its suppliers.

Mindtree’s Digital Health Passport for Travel

Post-pandemic passenger air travel is constantly evolving due to border restrictions and COVID-related mandates. The need of the hour for airlines is to have a comprehensive and adaptive solution that informs and educates travelers, airline staff, airport authorities and government in real-time about COVID test requirements, safety protocols, vaccines and other regulations. Mindtree’s Digital Health Passport for Travel solution, which is built using Hyperledger Fabric blockchain technology, promises to do exactly this and thereby make post-pandemic global airline travel seamless, hassle-free, and safe. 

MiFix Gateway

KrypC partnered with New Street Technologies to implement a blockchain marketplace for lending built on Hyperledger Fabric. MiFix Gateway is a distributed private network where participating financial institutions can access qualified leads and compete for customers seeking loans. Lenders view the credit score and personal information of each lead and offer competitive loans based on this information. MiFix provides a single platform where banks can earn revenue from loan disbursements and customers can obtain the most competitive rates while maintaining complete control of their data.

MiFiX connects remittance providers and banks to reduce interest rates. Though there have been efforts made by banks and financial institutions to provide affordable loans to rural parts of society, the last mile cost of collecting the loan pushes the cost to beyond affordable levels. By connecting the remittance companies in various corridors and lending institutions in India through a blockchain network, MiFiX is facilitating the sharing of remittance and loan information in a trusted and immutable fashion eliminating the collection cost. 

SnapCert

SnapCert is a blockchain-based Credential Authentication platform for universities, colleges and institutes. Offered as a SaaS platform by Snapper Future Tech, SnapCert equips education customers to issue and verify credentials on a blockchain, ensuring no fraudulent credentials can be issued in their name. 

Customers include Kushal, a social organization that trains unskilled labour under Indian government National Skill Development program. With SnapCert, verifiers can get real-time verification of Kushal credentials directly from the primary source of the data simply using the last four digits of the credential holder’s Aadhaar id and the name. The solution solves the problem of misplaced paper credentials and reduces the trust deficit by providing easy access to credible credentials that prove the holder’s construction training. It also helps Kushal manage long term record keeping for the skilled workers, connect stakeholders that need the data and increase transparency and ease of doing business.

SnapCert is built using Oracle Blockchain, which is powered by Hyperledger Fabric.

Secure Logistics Data Exchange 

The Secure Logistics Data Exchange (SLDE) platform was launched by the Ministry of Commerce of India to digitize the generation, exchange, and compliance verification of 36 document types commonly used by banks, customs, freight forwarders, exporters, importers, and transport operations. The SLDE platform, which runs on the Hyperledger Fabric-based Oracle Blockchain, is a solution to replace the present manual process of generation, exchange and compliance of logistics documents with a digitized, secure and seamless document exchange system. It was developed by CargoExchange in conjunction with a number of banks (ICICI, Axis Bank, State Bank of India and HDFC Bank) and the ministry’s Logistics Division.

Tech Mahindra Document Solution

Tech Mahindra, in collaboration with a partner, has built a SaaS platform allowing companies to securely share sensitive documents with anyone within or outside the organization.

Splunk Adds Hyperledger Fabric Data Visibility into Mix, Powers New Blockchain-Based Content Management Solution for S&P Global

By Hyperledger Blog, Finance, Hyperledger Fabric, Member Case Study

Read the full case study here.

Large organizations have always struggled to get visibility into their data. Frequently, data comes in many sources and formats while also being siloed across the organization. DLTs add ledger data and metadata to the mix.

Similarly, consortiums need to interoperate with each other. Yet organizations often use disparate tools for logs, metrics and tracing. All these are deployed on different clouds or on-prem. Then they build their own tools to take data from the ledgers and put it into a SQL database. Consortiums may include competitors who don’t trust one another, so they don’t want to share data. But, if no one shares data, it can be challenging to determine if an organization has a problem or if it lies in the network.

Splunk, a company focused on removing barriers between data and action, took on this challenge by creating open source solutions that allow the ingestion of ledger data and corresponding metadata while correlating with other data sources. 

Splunk’s customers include 92 Fortune 100 companies. Meeting their needs was critical so Splunk asked a lot of questions. They learned that many customers used Hyperledger Fabric, and it was fairly straightforward to ingest that DLT data. Splunk pulls in data without caring about structure, schema, or form so there was no need to format Hyperledger Fabric data before ingestion.

The next questions were about what they could do with the Hyperledger Fabric data. Users could analyze and correlate blocks and transaction data with other data they had in Splunk. But conversations with customers revealed they wanted more, including chaincode events, metrics, and, most recently, private data collections.

Initially, Splunk focused on uses from an IT perspective. Then the focus shifted to security. Customers wanted to know what else they could do to secure their infrastructure. Keeping it up and running was important, but so was making sure nothing would compromise their Hyperledger Fabric environment

One of those interested customers was S&P Global, which delivers data, research, and credit ratings, among other things, to governments, companies, and individuals. In 2019, it was entering a new region. S&P took this opportunity to explore modern technologies and new ways of doing business. It decided to build a content management solution from scratch with innovative technology and security.

Splunk’s Hyperledger Fabric-based applications caught S&P’s attention. Leveraging the Fabric data in Splunk meant S&P could now get user interactions and metadata—like who uploaded documents or modified documents and when. S&P developed applications to retrieve that metadata and present it to the user for document searches. This opened up possibilities for providing an audit trail.

The resulting solution, S&P Global Secure Vault, is multi-cloud, multi-tenant, and secure, and it is ready to scale to multiple regions and multiple participants. In the solution, S&P uses Splunk for three primary areas. The first is infrastructure monitoring on the operations of different components. The company wants to make sure the system stays healthy and the right teams are alerted if there’s an issue. The second is visibility into the events happening within the blockchain network. And third is business activity monitoring, which includes searching for document metadata.

Hyperledger worked with Splunk and S&P Global on a case study that details this blockchain-based secure content management system and how the companies partnered to add visibility into business transactions, making them indexable and searchable. It also delves into Splunk’s commitment to open source software and plans for helping customers that use Hyperledger Fabric get even more from their data.

A Hands-on Approach to Growing the Blockchain Talent Pool

By Igor Ioshpa, Norilsk Nickel Blog, Education, Hyperledger Fabric

One of the biggest barriers to growth for the blockchain industry is the availability of developers with the right skills and training. At Norilsk Nickel, we are tackling that problem directly with the Blockchain Master’s Program, which we launched in 2019 in partnership with MIPT and IBM.

Norilsk Nickel is constantly introducing and using advanced engineering technologies, and it is therefore logical that the company has focused its attention on blockchain technologies. In addition, working with students is one of the most important areas of the company’s activities. This has become the background for creation of a Blockchain Master’s Program in cooperation with the major technology players leading in their respective fields.

The Blockchain Master’s Program is based in the Moscow Institute of Physics and Technology, which is among the Russian technical universities regularly included in the top international rankings. MIPT is always interested in the development and implementation of educational programs in new promising areas. Educational programs at MIPT embrace numerous high-tech areas in partnership with Russian and international industrial companies.

One of the challenges in creating the Master’s Program was the fact that this was essentially the first Russian full-fledged educational program entirely dedicated to Distributed Ledger Technologies (DLT). The best experts in the market, from Russia and beyond, have been involved in the development of this educational course. Since all of them are practicing experts, the curriculum is updated on an ongoing basis taking into account the latest technology developments  as well as business expectations. All our lecturers work in the fields they teach for leading companies, mainly in the IT sector.

The primary task of the Master’s Program is not only to educate the students but also to enable them to gain real practical experience. Therefore, it was not easy to create a balanced curriculum. We aimed to combine both theoretical and practical disciplines to provide students with the most relevant knowledge as well as skills that will assist them in pursuing a successful business or academic career.

Our Hyperledger Fabric course, a cornerstone of the curriculum, provides the students with detailed information about the modular architecture of the Hyperledger Fabric platform and its capacities for creating blockchain applications. Given the fact that Hyperledger Fabric is the de facto standard for the enterprise blockchain platforms, the study of this subject takes two full semesters. As a result of the training, students create their own Hyperledger Fabric  projects helping to solve relevant application tasks.

One of Norilsk Nickel’s key education goals is supporting talented students. That’s why all applicants who have successfully passed the entrance tests can study free of charge. The Blockchain Master’s Program provides for paid internships as well, so any student who is serious about studying can get an offer as early as after the first academic semester. Meanwhile, the student can be engaged in both business projects and scientific and research activities. Norilsk Nickel, as a major industrial player, is committed to providing all interested students with the opportunity to build their career path concurrently with the study on the basis of real projects or scientific inquiries. 

Over the three years of the Master’s Program existence, we have witnessed vertical growth of the number of potential applicants, which indicates the importance of having such programs. To meet the demand, we made a decision to double the intake of students this year.

We have also revised and adjusted the curriculum to make the program as relevant as possible, based on the development of technologies and the requests formed by the business environment.

We actively participate in various events both within and outside MIPT to demonstrate our expertise in blockchain technology. Such events enable the students and the IT community to understand the relevance and importance of this technology and help us to make it more understandable for a wider audience.

To grow the Blockchain Master’s Program further, we plan to strengthen the level of scientific research to compete with top technical academic institutions around the world. We already have reached some preliminary agreements for this expanded focus.
