#HyperledgerAsia: Hyperledger-powered production solutions making an impact across Asia now

By Hyperledger Blog, Hyperledger Fabric, Hyperledger Iroha, Hyperledger Sawtooth

Enterprise blockchain has a global reach, and Hyperledger has a very active and innovative international community. This month, we are spotlighting solutions members have put into production through Asia that are transforming everything from digital payments and bond exchanges to supply chain, telecom, healthcare and security systems.

Read on for details about a range of #HyperledgerAsia solutions that are making an impact in markets across Asia now:

Bakong

National Bank of Cambodia officially launched Bakong — a multi-stakeholder system that enables instant and final transactions using digital Cambodian Riel (KHR) or United States Dollars (USD). Co-developed by the National Bank of Cambodia and Japanese/Swiss fintech company SORAMITSU based on Hyperledger Iroha, it is built to handle the needs of numerous banks and 17 million consumers.

BondEvalue BondbloX Bond Exchange

BondEvalue has been approved as a Recognised Market Operator (RMO) by the Monetary Authority of Singapore (MAS). It operates BondbloX Bond Exchange (BBX), the world’s first blockchain-based bond exchange to bring trading of a wide range of fixed-income securities to the mass market across the region.

BondEvalue officially graduated from the MAS’ regulatory sandbox on October 1, 2020. The move means that BondEvalue has successfully concluded proof of technology and business model. It is now no longer bound by restrictions such as limits on trading volume and disclosures specific to the sandbox model.

BBX allows for bonds to be traded in smaller sizes of US$1,000 unlike typical bond trades of at least US$200,000. 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.

dltledgers’ “plug-and-play” platform for cross-border trade and supply chain digitization

The current trade finance system is in dire need of an upgrade. Today’s operations between all involved parties are complex, costly, labor intensive, and inefficient. Also, in the aftermath of the global pandemic, it has become even more critical to shift entirely from a paper-heavy, manual business to digital.

dltledgers used Hyperledger Fabric to create the world’s leading “plug-and-play” platform for cross-border trade and supply chain digitization. All parties’ digital trades in the supply chain are recorded on the platform, providing banks the ability to go paperless and process payments seamlessly for LC issuance and trade finance quickly.

Currently, #dltledgers processes $100 – $150 million in trade finance per month, involving about 400 traders in which 20+ are large enterprises. About 45+ banks have joined the network to facilitate trade financing with prominent names such as ANZ, ADCB, DBS and TDB. To date, #dltledgers has processed more than S$3.2 billion in trade finance via its blockchain platform.

Hala System’s Sentry

Hala Systems is using Hyperledger Fabric alongside Hedera as part of its Sentry early warning system, which helps protect 2M+ people in Syria. Hala Systems uses both Hyperledger Fabric and Hedera to manage the metadata of user inputted and created media produced in conflict. The hashed metadata is simultaneously written to a private blockchain built on an IBM Blockchain Platform powered by Hyperledger Fabric and to Hedera Consensus Service. Hala Systems uses the IBM Blockchain Platform to act as its internal repository, preserving additional metadata to augment the auditable hash data sent to Hedera Consensus Service. With these two sets of records, any 3rd party can verify the information on the public ledger to match the image and, if necessary, its accompanying data stored on the private ledger.

MediConCen’s Blockchain Medical Ecosystem

Named as the Winner of Hong Kong’s “2020 Digital Disruptor” at the IDC Digital Transformation Awards (DXa) 2020, MediConCen simplifies medical insurance claims for medical community, insurers, and general customers using Hyperledger blockchain.

Traditional insurance systems require insured customers to present their physical card at the clinic, mail-in their medical receipts and claims for approval, followed by complicated administrative duties and time-consuming settlement procedures that many detest. Built on Hyperledger Fabric, MediConCen’s solution is the first blockchain medical ecosystem in Hong Kong, aimed at liberalizing the walled network to enhance the expected medical coverage, as well as greatly relieving clerical duties.

By automating the claim process through digital signatures and smart contracts, patients simply display their unique QR code for clinics to scan, thus revealing the corresponding plan and medical service they would provide. Offering efficiency and transparency to all parties involved with a complete and unique set of general ledgers and encrypting data of personal information to eliminate risks of leakage under the application of blockchain technology. This platform currently connects 200+ medical providers and 200,000+ medical insurance clients in Hong Kong.

Tech Mahindra’s plug-n-play solution to curb spam calls

By 2018, the spam call situation had grown grim in India, a country with more than 1 billion active mobile subscribers, causing bad customer experience and propagating of fake news and financial scams. The Telecom Regulatory Authority of India (TRAI) acknowledged UCC (Unsolicited Commercial Communication) or spam calls were a major nuisance to telecom subscribers across the country and a growing menace that needed to be tackled with immediate effect. Though TRAI had established a “Do Not Disturb” (DND) list in 2010 with more than 230 million subscribers on it, unregistered telemarketers continue to spam customers, obtaining their consent through fraudulent and questionable tactics. Through various internal and external assessments, DLT was selected as the underlying technology to curb the menace.

Tech Mahindra developed a plug-n-play solution, built on Hyperledger Fabric, to mitigate the problem. With the solution successfully deployed across three major telcos in India, Tech Mahindra has access to >50% market. This solution has potential to have a global impact. Tech Mahindra has already reached out to the Federal Communications Commission (FCC) in the U.S. market and is exploring opportunities to socialize it with U.S.-based telcos to address the pain points of robo-calling and caller ID spoofing are key pain areas that can be addressed by our solution.

By Hyperledger 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.

Hyperledger-Powered Education Solutions in Action

By Hyperledger Blog, Education, Hyperledger Aries, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha

Just before the age of COVID began in earnest, The New York Times ran a feature on “How Technology Is Changing the Future of Higher Education.” The rise of remote learning and other pandemic-related changes and challenges have added to the need and opportunity for technology-driven advances.

The Hyperledger community is doing its part to help the higher education market adapt to an increasingly digital world. Below we look at five Hyperledger-powered solutions that are at work now in the education market. They are helping colleges and universities modernize how they tackle a number of core tasks, including issuing and verifying academic credits, automating on-campus payments and managing students’ identity and privacy.

Read on for more about these #HyperledgerEdu solutions, built using a mix of Hyperledger technologies:

Byacco, an on-campus payment system

Soramitsu has officially released Byacco, a payment system based on Hyperledger Iroha, for the University of Aizu, Japan. Byacco is a system that allows students and staff of the University of Aizu to use an application on their phones to pay for goods in the cafeteria and university store and to transfer funds within the campus. To make a transaction, all they need is to scan or to provide a QR code, depending on the operation. Byacco’s technology also has high standards for transfers: it follows the EMV® QR Code specification and has bank application level financial security protocols. The keys that are used to authorise transactions on the blockchain are stored only on the device, in a secure storage, so that no one except the owner can access the funds. Students of the university can join the development of the system, thus acquiring skills in creating financial systems based on Hyperledger technologies.

DoDream, a “Study Abroad Platform”

Dain Leaders is an education solution provider for universities in Korea. It serves more than 45 Korean universities by providing services for students’ career path development. As part of that effort, Dain Leader is introducing its “Study Abroad Platform,” called DoDream, to support the extended education ecosystem of the universities, accreditation and related agencies, and prospective employers. Based on Oracle Blockchain Platform Cloud Service (which is powered by Hyperledger Fabric), the platform is an O2O service that provides foreign students with information on studying in Korea and a matching service with Korean universities.

Oracle Digital Certificates Solution

In the face of fast-changing demographic and economic drivers and student expectations, the current processes for issuing and verifying student certificates are too inefficient and time consuming. They can also lead to fraudulent or counterfeit certifications.

The Oracle Digital Certificates Solution, built on the Oracle Blockchain Platform (based on Hyperledger Fabric), provides a complete, end-to-end solution for educational institutions to issue verifiable tamper-proof and secure credential certification that improves the student experience after graduation and improves operational efficiency. The solution enables institutions to issue digital certificates along with transcripts and provide self-sovereign capability to the students who can share them securely with third parties through an access token.

This solution has been successfully deployed in production by customers like China Distance Education Holdings Limited (CDEL) and Taibah Valley University. CDEL uses Oracle Blockchain to share educational records and professional certifications across many educational institutions to help employers and recruiters verify the educational credentials claimed by individuals.

Many other institutions like national universities, employment agencies, government organizations, professional skills academies and universities that provide student grants/scholarships are using this solution as part of ongoing or planned pilots.

PwC Smart Credentials

Data is the new gravity in the world today and organisations are gravitating to and concentrating around trust as the ultimate currency in this data driven world. This trust is crucial for people to exchange information, especially in this digital age when trust is often violated.

With that premise, PwC developed Smart Credentials, a credential issuance, sharing, reviewing and revocation platform levegering the inherent core benefits of blockchain technology such as immutability, tamper-proof nature, transparency, authenticity and security.

Built using Hyperleder Indy and Hyperledger Aries to support the verification process, Smart Credentials has two key pillars: Authentication (you are who you say you are) and Authorization (genuine claim). Both are crucial ingredients of building trust in any ecosystem.

Smart Credentials recently won a “Bronze” medal for the Best Global Blockchain Innovation 2019 at the Reimagine Innovation awards (Backed by Wharton and QS) and is a finalist in the DataIQ 2020 awards “Best data product/ service” of the year category.

Verified.Me

As higher education moves deeper into online and remote learning for traditional and non-traditional students, colleges and universities are now offering a broader array of services that extend the campus experience to the digital realm. Beyond the advent of digital programming, educational institutions are also privy to sensitive personal student, faculty and alumni data from income and payment information to disciplinary records, healthcare and insurance information.

SecureKey Technologies’ Verified.Me service is one approach that supports education’s new digital and data privacy demands. This new digital identity verification service can help verify students, alumni and faculty in a timely and secure manner, strengthening educational institutions’ ability to expand their digital offerings with confidence – while also providing much-needed cost savings. Verified.Me is built using the IBM Blockchain Platform, which is based on Linux Foundation’s open source Hyperledger Fabric.

Join the conversation about solutions and applications supporting the higher education marketing with #HyperledgerEdu this month on social channels. Also, Hyperledger has an Education Architecture Special Interest Group that is open to all.

National Bank of Cambodia’s New Digital Payment System: How Soramitsu Helped Modernize Retail Payments Using Hyperledger Iroha

By Hyperledger Blog, Hyperledger Iroha

In the Kingdom of Cambodia in Southeast Asia, three-quarters (78%) of its citizens have no bank account, yet more than half own a smartphone. And even though the native currency—the Khmer riel (KHR)—has been stable for 20 years, most people there use the American dollar. Ever since a major UN mission in the mid-1990s, the price of everything from a cup of coffee to a car has been given in U.S. dollars.

Addressing these challenges and more, the National Bank of Cambodia (NBC) set out to see if a digital payment system could handle transactions faster and for lower cost than the existing system.

Could it promote wider use of the riel? And could that system run as a mobile app that any citizen with a smartphone could use to shop or transfer money to family or friends?

To find out, NBC partnered with blockchain developer experts Soramitsu on a retail payment system project that would modernize the country’s legacy retail payments with the help of the Hyperledger Iroha blockchain framework.

When most people picture a CBDC, they imagine an entirely new digital asset created out of “thin air.” The problem is, this new asset could distort a country’s monetary policy and affect its exchange rates. To be prudent, Cambodia’s central bank wanted to create a digital token backed by fiat currency stored safely in its vaults. The new payments platform would become a way to move around digitized cash, while preserving the creditworthiness and security of the central bank.

The resulting project, called Bakong, is the first retail payments system in the world using blockchain technology. 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.

The pilot project went live in July 2019 and ran successfully with a network of 14 banks supporting more than 10,000 users, laying the groundwork for a large-scale rollout later this year.

Hyperledger teamed up with Soramitsu on a detailed case study covering the planning and implementation of Bakong, including key goals, milestones, security considerations and core technology requirements, as well as a preview of rollout plans and new features.

2019 Summer Mentee Project Update: Integration of EVM from Hyperledger Burrow into Hyperledger Iroha

By Ivan Tyulyandin Blog, Hyperledger Burrow, Hyperledger Iroha, Hyperledger Mentorship Program

Hello, my name is Ivan Tyulyandin. I am a student at Saint Petersburg State University. I took part in the Hyperledger Internship Program, working with Andrei Lebedev (my mentor), Iurii Vinogradov and Eugene Kovalev from the Hyperledger Iroha team.

Hyperledger Iroha is a straightforward distributed ledger technology, inspired by the Japanese Kaizen principle — eliminate excessiveness. Users can create and manage their assets via Iroha commands. Iroha is written using C++, Protobuf, Boost and GTest. There are no smart contracts in Iroha.

Introduction

Hyperledger Burrow provides a modular blockchain client with the possibility to change different parts of the system. One modular piece is a permissioned smart contract engine, partially developed to the specification of the Ethereum Virtual Machine (EVM). Burrow is developed using language Go.

The main purpose of this internship was to integrate EVM from Hyperledger Burrow into Hyperledger Iroha. Since Ethereum is de facto the most known platform for smart contract development, the integration will let Ethereum developers use Iroha as a new blockchain in distributed applications.

Project Components

The starting point was identifying the main components the project needed to address:

First of all, there should be a way to pass data (such as Ethereum bytecode, caller and callee) from Hyperledger Iroha to Hyperledger Burrow EVM. For this purpose, a new command to Iroha has to be added.
Another issue is to connect Golang and C++ code to bind Iroha and EVM.
The next step is to implement a special Burrow API to store EVM accounts data in Iroha.
The final requirement is new functionality testing.

Challenges

One of the challenges was to get deeper into the codebases of Hyperledger Burrow and Hyperledger Iroha. Existing integration examples of Burrow EVM to Fabric and Sawtooth gave me a nice understanding of what to do. From the Iroha side, Andrei Lebedev led me through the Iroha source code.

Results

With this information, I was able to develop a new command EngineCall. I made a wrapper using CGO (special go compiler mode that generates C library from Go source code) that Iroha uses to call Burrow EVM. Now an implementation of Burrow EVM API can send requests to Iroha for modification of its state via Protobuf messages. Every EVM account is stored in a technical account in Iroha. EVM account storage is emulated in the technical account details (which is key-value storage). All of this work was QA’d by writing and completing module and integration testing.

What comes next

More features can be added to this integration. The first one is web3 interface implementation, which will call remote EVM instance or use a local one. The next possible improvement is to add permissions to an Iroha account that represents an EVM account. Also, the current support of Burrow EVM in Iroha is not full, since there is no catching of EVM logs.

2019 Summer Mentee Project Update: Integration of Hyperledger Iroha into Hyperledger Explorer

By Ruslan Tushov Blog, Hyperledger Explorer, Hyperledger Iroha, Hyperledger Mentorship Program

Hyperledger Iroha is a next-generation permissioned DLT initally contributed by Soramitsu. It provides asset and identity management, multi-signature and batch transactions. During the internship, I visited the Soramitsu office and communicated with Iroha development team.

Hyperledger Explorer is a tool that shows information from DLT networks. Initially, it was built to support for Hyperledger Fabric, with the expecting support for more DLTs would be added. Our goal was to add support for collecting and viewing Iroha transactions and Iroha-specific information to Hyperledger Explorer.

Accomplishments:

We implemented an integration of Hyperledger Iroha into Hyperledger Explorer. Now, Hyperledger Explorer shows information about Hyperledger Iroha peers, blocks, transactions, roles, domains, accounts.
We found and fixed some ambiguous statements in Hyperledger Iroha documentation.
We simplified code of our project by using open-source GraphQL framework developed by Facebook.

For a deeper dive into the work, read my full project report here.

I am very grateful for the support of my mentor, Ales Zivkovic, as well as Hyperledger for the opportunity to learn and contribute to open source Hyperledger projects.

Welcome Hyperledger Iroha 1.0: Flattening the DLT learning curve

By Makoto Takemiya, Hyperledger Iroha Contributor and Co-founder/CEO of Soramitsu Blog, Hyperledger Iroha

My first experience running a blockchain was when I first launched a Bitcoin node about six years ago. I got into Bitcoin out of curiosity and because the idea of sending value as digital data across the Internet was a very compelling idea.

Since those early days of experimentation, blockchain and DLT have emerged and found its place in enterprise — companies, individuals, consortiums want to get rid of non-transparent resource allocation, corruption, and fraud. Today, diamonds are registered on a blockchain, insurance companies know if you registered your MacBook at several places, and cross-border payments can operate more efficiently.

While blockchain technology has passed its longevity test, the software in general is still far from being integrator-friendly, developer-oriented, and straightforward; specifically when it comes to using distributed ledger technology instead of a database. This is where Hyperledger Iroha is different. With Hyperledger Iroha, it took me about 10 minutes to start building a blockchain. And now the Hyperledger Iroha team is releasing its first production-ready version, offering a faster, less complex path to DLT deployment. Welcome Hyperledger Iroha v1.0!

When it comes to solutions for business, it is critical that the technology is fit for the task and easy to integrate. Moreover, it must be reliable and safe so a business can trust it. Hyperledger Iroha provides safety with its decentralized consensus algorithm and reliability with a tested set of commands and queries. With them you can be sure that the code will do exactly what it is supposed to do — whether you want to add information to, or get information from, the ledger.

For this release the team prepared a special set of improvements:

New native client libraries deliver cross-application support for desktop/server (on Java, Python, C++) or mobile (iOS, Android (Java)) applications. You only need to get an idea of the client application and you are ready to go! Take a look at desktop and mobile application examples: on Java or JS: https://github.com/soramitsu/iroha-wallet-js
Novel, asynchronous consensus algorithm supporting one step agreement on votes with vote collection optimizations included (Yet Another Consensus; YAC). This means that even if a node is faulty, your decentralised ledger will still be up and running correctly. You can now focus on implementing your business application, leaving the question of whether you can trust partners’ nodes to Hyperledger Iroha.
Multi-signature transactions, or as we call them, MST, are now ready for production use. What does it mean for your business? It means that you can set a quorum, such that transactions from your company’s wallet will need several signatories instead of just one — just like in traditional banking, but quicker and more secure. This can also be used to model complex business processes in a secure and automatic way.
New backwards-compatibility allows you to integrate Hyperledger Iroha into your business and be sure that no breaking changes will affect it.

Hyperledger Iroha is already gaining strong traction with the community and enterprises:

Alexander Yakovlev from Moscow Exchange Group’s National Settlement Depository is using Hyperledger Iroha in D3 Ledger, and he said: “Global business is always terrific, and we looked for a solution that fits our requirements and is 100% open-sourced and oriented for the specific needs of our task. Features such as Iroha’s account management and supportive community, in addition to Soramitsu’s KYC application, were key factors in our decision to use Iroha for D3 Ledger. Iroha’s existing adoption in several countries and the practical use case with the Cambodian central bank were additional benefits.”

Hyperledger Iroha is already used in asset management, identity management, and payment systems. From simple asset transfers to secure information exchange about customers, Hyperledger Iroha can be used to empower a multitude of use cases, all without the need to program custom smart contracts.

Last year, I wrote a paper about Sora Identity, an implementation of a self-sovereign identity protocol using Hyperledger Iroha. Since then, we have worked on expanding this app and now we have a working product for KYC, targeted towards financial institutions. We are now expanding this to be at the core of the Sora decentralized autonomous economy, an exciting new type of economic system, geared towards empowering the creation of new goods and services.

Try it – simplicity and friendly support from the community will surely help you find your own way of improving your project with Hyperledger Iroha blockchain.

Developer showcase series: Zilya Yagafarova, Soramitsu

By Zilya Yagafarova Blog, Developer Showcase, Hyperledger Iroha

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 technology? How did you get involved in blockchain? In Hyperledger?

I am a project manager for Soramitsu and I work with a team of highly skilled developers writing code for different platforms and also QA and DevOps specialists.

I have been interested in IT since I was a child and, by the age of 14, had already decided to commit myself to studying computer technologies. After graduating from university, I worked as a technical support engineer, an engineer of information systems’ implementation, and a business and system analyst. Now, I am a project manager.

The thing about IT is that you have to constantly learn new skills and work on self-development. Technology is advancing constantly, so you should become a better version of yourself everyday.

A few years ago, blockchain technology appeared on the market–it was new and seemed promising. My friends had already worked on Hyperledger projects and inspired me to join them.

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

I am a project manager of Project Bakong, a payment system that is developed in collaboration with the National Bank of Cambodia (NBC) using Hyperledger Iroha blockchain. We have finished with the implementation of the core system and will to launch a pilot with dozens of Cambodian banks, which is very exciting. Some of our technology is also being used in a decentralized autonomous economic system called Sora and in a decentralized digital asset custodian and settlement service called D3 Ledger. Collaborating with other projects is intellectually stimulating and enjoyable.

We decided to use Hyperledger Iroha because it is created for financial institutions to build highly performant systems that can scale to large numbers of concurrent users (in our case it is the population of a whole country!) and it proved itself capable of performing the task, in my experience.

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

The main target of the project I am working on is to help expand access to financial services for Cambodian people by providing instant payments through a mobile application and robust, modernized infrastructure.

Blockchain is a new and very promising technology, especially when it comes to finance – transactions in Hyperledger Iroha have settlement finality and the data are impossible to corrupt.

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

Design first–analyse the task from every angle and only then write the code that you fully comprehend; do not rely on random chance because it will not work.

What advice would you give for other women who want to build their careers in development? In blockchain?

Believe in yourself and in your capabilities. Then just work hard.

What technology could you not live without?

That must be maps and translation software. I travel a lot because our company is as decentralized as its products, and it would be impossible to discover the world as I do now without a way to communicate and navigate in it.
