Call for Applications: 2022 Hyperledger Mentorship Program

By Hyperledger Blog, Hyperledger Aries, Hyperledger Besu, Hyperledger Bevel, Hyperledger Cactus, Hyperledger Fabric, Hyperledger Indy, Hyperledger Mentorship Program, Hyperledger Ursa

Want to jump start a career in blockchain development? Ready to build hands-on skills developing leading-edge open source technologies? Looking to work directly with mentors who are invested in you and your work? Then the Hyperledger Mentorship Program is for you. 

Now in its sixth year, the Hyperledger Mentorship Program provides a structured and guided learning opportunity for anyone, at any career stage, looking to get started in the open source movement. With full and part time options, fully remote work and a stipend, the projects are designed to be a pathway to becoming a contributor to the Hyperledger community that work for students, people in career transition and anyone else who wants to develop or sharpen their knowledge of cutting-edge blockchain technologies. Applications are now open.

This year, the Hyperledger Mentorship Program has grown to 30 planned part and full-time projects covering a range of technologies, challenges and technical difficulty levels and includes non-development projects such as Ecosystem Analysis and Developer Marketing. Each project is designed and proposed by active members of the Hyperledger community. Those who propose the projects serve as the mentors and work closely with their mentees on developing a project plan, setting milestones and solving problems. Mentees can expect regular evaluations and feedback. For more about the program, including the schedule and stipend details, go here.

Over the last five years, more than 70 mentees have completed Hyperledger Mentorship projects. Each of these mentees have made concrete contributions to Hyperledger projects and built important connections in the community. Some, like Bertrand Rioux, have gone on to become mentors themselves:

“I was accepted into the Hyperledger mentorship program last year after seeking a community to help advance my professional goals of developing software for climate action. I was fortunate to find a diverse group of mentors that helped me build the knowledge and skills I needed to effectively contribute to the Hyperledger open source community and to have the opportunity to develop technical expertise in a field I was actively working in. In addition to delivering a secure identity management solution for a Hyperledger Fabric Network, I started contributing my own ideas to the open source operating system for climate action. As a result, I am now taking a leadership role in the community. In addition to serving as mentor in this year’s program, I proposed a project on reducing waste emission in the oil & gas industry that was accepted.” – Bertrand Rioux, Independent Energy Consultant and Mentor for the Multiple Data Integration to Hyperledger Fabric Climate Accounting Network project

To learn more about the Hyperledger Mentorship experience and outcomes, check out these  spotlights on last year’s projects with highlights from both the mentors and mentees.

Read on for descriptions of some of the projects planned for this year:

Multiple Data Integration to Hyperledger Fabric Climate Accounting Network

The Hyperledger Labs blockchain-carbon-accounting project includes a Hyperledger Fabric network for recording the carbon and Greenhouse Gas (GHG) emissions that cause climate change.  Since there are many activities that cause such emissions, the network is designed to accept data from multiple sources of measurements.  In this project, we will demonstrate integrations from measurement sources with blockchain networks by integrating the ThoughtWorks cloud computing emissions calculator, the NREL OpenPath mobile application, and other web- and mobile-based API’s sources to turn instrumented readings into emissions measurements. It will leverage previous projects involving Hyperledger Cactus, Vault security engines, and client security for Hyperledger Fabric.

The expected outcomes of this project are

  • Successful integration of the mobile apps and API’s with Hyperledger Fabric
  • Benchmark comparison of Hyperledger Fabric and alternatives
  • Documentation and tutorials for integrating future data sources

Demonstrate Interoperability using Hyperledger Bevel and Cactus

Hyperledger Cactus support ledger Interoperability but use a local deployment for testing; Hyperledger Bevel supports production-worthy deployments. This project aims to support Cactus deployment using Bevel to demonstrate production-like usage of Hyperledger Cactus. 

The steps will be following:

  1. Deploy a Hyperledger Fabric network using Bevel on a Managed Kubernetes cluster
  2. Deploy a GoQuorum network using Bevel on a Managed Kubernetes cluster (can be the same cluster for simplicity).
  3. Make changes in Hyperledger Bevel code to deploy the Cactus connectors in both the above networks.
  4. Run Cactus test cases.

The expected outcomes of this project are

  • Successful Interoperability testing using Cactus on  production like DLT networks.
  • Update to Hyperledger Bevel code to automatically deploy the Cactus plugins.
  • Update to Documentation of Bevel and Cactus.
  • Detailed tutorials and learning materials which would benefit Bevel and Cactus communities.

Hyperledger Fabric-Ethereum token bridging

One of the key use cases of blockchain integration is asset bridging: in essence, “locking” an asset (typically, a native coin or token) in a smart contract on its authoritative ledger and making available corresponding, newly minted (wrapped/shadow/…) assets on another. By now, bridging is supported by quite mature solutions in the cryptoworld; however, the same is not true for “consortial” distributed ledger technologies. At the same time, such functionality can be expected to become an important requirement in the not too distant future: for instance, a central bank may choose to create a high performance, Hyperledger Fabric-based Central Bank Digital Currency (CBDC) ledger with a strongly controlled set of “smart contracts,” but allow controlled “bridging out” of the currency to dedicated distributed ledgers of industrial/enterprise cooperations. 

Last year, a CBDC prototype with such functionality was created at the Dept. of Measurement and Information Systems of the Budapest University of Technology and Economics (BME), in a research project supported by the central bank of Hungary (MNB); our initial experience with a custom Hyperledger Cactus and TokenBridge based solution showed that this is a problem worth more targeted experimentation and systematic R&D.

The expected outcomes of this project are

  • Report on asset representation in Hyperledger Fabric and mapping approaches to standard Ethereum tokens
  • Report on bridging approaches and technologies and their applicability for bridging from/to Fabric
  • Requirement specification
  • Design specification
  • Prototype implementation and small demo of bridging at least ERC-20 or ERC-721 to Ethereum – and back

Client Connector for Hyperledger Besu

Develop a connector that provides both synchronous and asynchronous modes of interacting with a running Hyperledger Besu node. The connector would act as an interface between an enterprise application and the Hyperledger Besu node for data ingestions and it could provide event subscription options.

The scope of the project would also include an end-to-end test on a sample network.

The expected outcomes of this project are

  • Design and implement the connector.
  • A new Hyperledger Labs project is proposed with a documentation.

GVCR: Secure Verifiable Credential Registries (VCR) for GitHub & GitLab

As conceptualized and standardized by the W3C, the Verifiable Credentials protocol is one of the three pillars of Self-Sovereign Identity, together with the Decentralized Identifiers protocol (DIDs) and Distributed Ledger Technology (or Blockchain). The project aims to design and build a verifiable credential registry (VCR) on GitHub repository, namely GitHub-based Verifiable Credential Registry (GVCR), by leveraging existing GitHub APIs, and other open-source tools provided by other Hyperledger projects, such as Hyperledger Aries, Hyperledger Indy, and Hyperledger Ursa. The basic architecture is already built. For more details about the conceptional design and workflows, please refer to the GitHub repository GitHub-VCR.

The expected outcomes of this project are

  • A verifiable credential registry based on one or more GitHub repositories.
  • Command-Line utility to automate the process of verification of a credential.
  • Proper test cases and documentation.
  • Codebase maintained with proper read me document.

The Hyperledger Summer Mentorship Program is part of the Linux Foundation’s overall commitment to mentoring. The application process is being managed through LFX Mentorship, a platform created by the Linux Foundations to train future open source leaders. 

Check out the full list of mentorship projects and start your application today. The deadline to apply is May 10. Mentees from diverse communities are encouraged to apply. All are welcome here!

#HyperledgerInterop: Delivering Cross-Chain Interoperability with Hyperledger Technologies

By Hyperledger Blog, Hyperledger Besu, Hyperledger Fabric, Hyperledger Labs

We kicked off #HyperledgerInterop month with Why is Interoperability Needed?, which explains the drivers for interoperating networks and then deep dives into the different Hyperledger technologies tackling the challenge. 

Below, we continue the conversation with highlights of some leading-edge efforts to deliver cross-chain interoperability built using Hyperledger technologies:

Cross-Ledger Interbank Settlement: As part of a series of wholesale CBDC trials, Banque de France, the French Central Bank, completed cross-ledger interbank settlement transactions in a multi-blockchain environment. Conducted in association with HSBC and IBM, this test case entailed the issuance and trading of digital bonds, settled instantly using CBDC. Transactions occurred across blockchain environments operated by HSBC for the custody of the assets and by the Banque de France for the securities settlement and the CBDC. In the trial, Hyperledger Fabric and R3’s Corda were able to transact with each other using Weaver, a Hyperledger Lab initially contributed by IBM. 

Digital Green Bond Project: The Bank for International Settlements Innovation Hub (BIS) Innovation Hub and the Hong Kong Monetary Authority (HKMA) set out to improve efficiencies in the distribution of green bonds and more insightful reporting on the environmental impact of projects supported by the bonds through Project Genesis. The aim is to develop digital platforms that will allow investors to buy and sell bonds that support green projects with real time access to both the financial performance of the bond and such metrics as clean energy created and O2 reduced by the investment. The first prototype from Project Genesis was developed with Digital Asset in partnership with GFT and leveraged Daml smart contracts as well as Digital Assets interoperability protocol layered over Hyperledger Besu and Hyperledger Fabric blockchains. It achieved real-time synchronization across these two ledgers while preserving the level of privacy demanded by regulated bodies. The prototype drives market efficiency with a unified view of the entire trade lifecycle and a single source of truth that automates market rules and adheres to market regulations.

Interoperable platform for international exchange of CBDCs: The BIS Innovation Hub, Hong Kong Monetary Authority, Bank of Thailand, People’s Bank of China, and Central Bank of the United Arab Emirates are working together on a prototype multi-CBDC platform for international payment that joins up national digital currencies on a common interoperable platform. During the Phase 2 and 3 explorations of the project, mBridge (formerly Inthanon-LionRock), they worked with ConsenSys on a Hyperledger Besu implementation that completed an international exchange of multiple CBDCs in seconds as opposed to several days and has the potential to reduce costs to users by up to half. 

Multichain Trade Settlement: In January, 2022, Tokio Marine & Nichido, NTT DATA, STANDAGE and TradeWaltz jointly conducted a demonstration experiment for a new trade settlement system in which electronic B/Ls (bills of lading) and digital currencies were exchanged simultaneously using two different blockchain networks. The simultaneous transfer of digital assets and digital currencies was conducted by Datachain with the cooperation of NTT DATA, and leveraged YUI, a Hyperledger Lab that was initially contributed by Datachain, to interconnect Hyperledger Fabric and Ethereum. Datachain successfully confirmed that two assets can be exchanged simultaneously by DVP settlement between digital assets on services built with Hyperledger Fabric and digital currencies on Ethereum.

Hyperledger Technologies Dominant for Enterprise Blockchain Deployments on 2022 Forbes Blockchain 50

By Hyperledger Blog, Hyperledger Besu, Hyperledger Cactus, Hyperledger Fabric, Hyperledger Indy

“You’ve come a long way, blockchain!” declares Forbes in the 2022 Blockchain 50, an annual list that tracks how billion dollar companies from around the world are innovating with the technology. Now in its fourth year, the Forbes Blockchain 50 has evolved just as much as this market. 

The mainstreaming of both cryptocurrencies and their underlying technologies have reshaped business around the world. For many companies on the list, the innovation comes from new models of investing and transacting in crypto markets. But, as Forbes put it, “Cryptocurrencies hog the spotlight, but blockchain’s biggest innovations are below the surface, saving billions each year for the world’s largest companies.”

For the companies on the list that have made blockchain technology a core foundation of their business operations, Hyperledger technologies, particularly Hyperledger Fabric, continue to be the standard. At least 13 companies on this year’s list have built their strategic networks on Hyperledger technologies, far outpacing any other technology or platform among these kinds of deployments. 

Hyperledger Besu, Hyperledger Indy and Hyperledger Cactus are also named as key technologies by companies on the list, highlighting the value of Hyperledger Foundation’s multi-project strategy.

Congratulations to Hyperledger Foundation members DTCC, Fujitsu, Nornickel, Oracle, Tech Mahindra, Tencent and Walmart for making the Forbes Blockchain 50 in 2022. Read more on how Tech Mahindra, Walmart and other member companies are using Hyperledger technologies in our growing library of case studies.

Public Mint Lowers Barrier to Entry for Blockchain-Based Investing and DeFi with Hyperledger Besu

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

Read the full case study here.

The cryptocurrency market will reach nearly five billion USD by 2030, according to recent market research. With impressive returns and projected growth, it’s no wonder people want to get involved in decentralized finance (DeFi).

But for those who don’t already understand crypto assets, there are significant barriers to entry. What’s a wallet? Do I need one, and how do I get one? What are keys? How do I protect them? What platform do I use?

And there’s also the problem of risk. Crypto users have grown comfortable taking chances in the space. But the average person is used to more trust, assurances, and transparency when it comes to their money.

Public Mint, a Fintech firm with offices in the US, UK and Europe, decided to create a graduated introduction into blockchain-based investing. To do so, Public Mint began with what users already know: traditional banking and fiat currencies like the US dollar.

Public Mint wanted a platform with a one-to-one equivalency between US dollars and a synthetic version of the dollar on their blockchain. This means every synthetic “on-chain” dollar maps to a corresponding US dollar held at one of Public Mint’s regulated custodian partners.

Users would not move dollars from one account to another, the same way traditional banks do. Rather, the physical dollars stay in a custodian bank. Users transfer ownership of these physical dollars using an instant-settlement, low-cost blockchain.

To develop its system, Public Mint experimented with the blockchain technologies available in 2018. Eventually, it decided on an Ethereum-based technology stack called Pantheon developed by the Pegasys team at ConsenSys. For Public Mint, tapping into the large community of Ethereum developers was an important part of the decision.

About a year afterward, Pantheon became Hyperledger Besu, an open source project under the umbrella of the Hyperledger Foundation, which pleased Public Mint as that brought them closer to the Hyperledger and corporate communities.

Public Mint’s network launched in July 2020 with its web wallet payment system. To date, more than 3,800 wallet addresses have been created since Public Mint’s launch. It has more than USD$2.9 million in on-chain value, and the platform has validated more than 28,000 transactions.

Building on the initial wallet capabilities, Public Mint now also has introduced the EARN Program. EARN is for users who want to take the next step into DeFi investing but don’t want to manage multiple wallets or private keys.

Hyperledger worked with Public Mint on a case study that details the launch of this network and the pathway it creates for bringing DeFi to a broader audience. It covers the core architecture of the Public Mint system, its blockchain-based banking and DeFi business models and the roadmap for future applications.

A Look at Hyperledger-Powered Financial Services Solutions in Action

By Hyperledger Blog, Finance, Hyperledger Besu, Hyperledger Fabric, Hyperledger Firefly

It is #HyperledgerFinTech month, so we are spotlighting solutions where Hyperledger is at work across the finance service market. Read on for details on applications and solutions leveraging a mix of Hyperledger technologies to invent and reinvent a range of services, including eKYC, insurance claims processing, accounts reconciliation, specialty trades and more:

AnaMeen

AnaMeen is a multi-organizational eKYC solution from Ahli Fintech involving Jordan Ahli Bank and Zain Jordan, a mobile telecom provider. This eKYC-as-a-Service, built on the Oracle Blockchain Platform (OBP), aims to remove the friction in the current KYC and onboarding process challenges faced by all banks and financial institutions and to provide greater financial inclusion for all Jordanians. It delivers an enhanced and secure customer experience, with a 10-day account opening process now made instantaneous. Ahli Fintech leverages augmented intelligence and deep learning technologies to verify the identity of the AnaMeen users’ government-issued identity documents. It collects the four-signature specimens of the users and verifies the client signature on file during a verification video-call with an AnaMeen agent. Customers verify their information and their identity is matched based on their facial biometrics during the video-call. Each customer’s identity is uploaded to a smart contract on OBP to verify and endorse it, storing it in the “Meen World” immutable ledger distributed across the permissioned blockchain network. The solution, which is powered Hyperledger Fabric, enables self-sovereign instant KYC data sharing, with full control in the users’ hands in full compliance with international data protection and data privacy standards. It is accessible via the “Meen World” eKYC-as-a-Service partner portal, where entities can request access and users can grant access in order to use the services provided by these entities, including instant digital onboarding with subscribed banks.

The Institutes RiskStream Collaborative

The Institutes RiskStream Collaborative is the risk management and insurance industry’s first enterprise-level blockchain consortium that brings together experts and developers to advance insurance-specific use cases via Canopy 3.0, a custom blockchain architecture running on Kaleido that leverages Hyperledger FireFly.

A major source of inefficiency in the life & annuity insurance industry is that life insurers lack a single source of truth for processing death benefits and claims. For all participants, the multiple handoffs between systems and people increase time, cost, and risk.

The Mortality Monitor project, a blockchain-based technology solution led by RiskStream Collaborative, offers a single source of digital decedent information required to process a claim. Instant notification helps carriers proactively identify potential deaths more quickly, reducing the burden on the beneficiary, and shortening the cycle time.

NPLUS 

Sydema has implemented NPLUS, a digital and independent platform that makes the exchange of non-performing loans (NPLs) simple, reliable and secure. This transaction platform provides an exchange where banks and investors can trade NPLs based on standardized data templates, which helps to increase transparency and liquidity in this process. It also reduces the wide bid-ask spreads on NPLs, thus contributing to a faster clean-up of bank balance sheets. NPLUS uses an independent blockchain solution developed by Mangrovia on the Hyperledger Fabric-based Oracle Blockchain Platform so that the tracking and storage of loan portfolio and collateral data is referenceable on the marketplace and NPL trading operations are transparent and persistent. 

Public Mint

Public Mint is the first fiat-native public blockchain that allows people, companies, applications and banks to interact in frictionless new ways around money. Prior to Public Mint, transactions required banking and exchange off-ramps, meaning there was no such solution offered by payment providers that was blockchain compatible or that enabled instant settlement in fiat. Public Mint, which is built on Hyperledger Besu, is an open blockchain blended with an API platform that allows fiat money to get all the benefits of a cryptocurrency, minus the volatility and complexity. People and businesses from all over the world are free to build all kinds of fiat-based applications and services on top of Public Mint, fueled by money as we know it – without the limitations of traditional banking rails.

SECURUS

Supermoney has introduced SECURUS, a specialist insurance product that addresses key issues in insurance accounts reconciliation between the customers, brokers, insurer, and re-insurers. It is an end-to-end finance and accounts reconciliation solution incorporating underwriting and claims functions. Using tokenization to create and manage accounting of real-world payment flows across multiple siloed systems, the Oracle Blockchain Platform-based network covers MGAs, brokers, and underwriters. It enables ingestion of data from multiple systems, provides Bordereau reports on money flows related to premiums paid or claims with real-time updates, and partner contracts, including commission rates. Built with Hyperledger Fabric at its core, SECURUS significantly reduces the effort and cost of manual reconciliation and avoids human errors or fraud impacting regulatory compliance, reinsurance accounting and profitability.

Symbridge

Symbridge is a blockchain-based digital asset exchange for institutional and accredited investors. Built on Hyperledger Fabric’s open-source protocol, Symbridge’s advanced technology leverages the enhanced security, immutability, and externally-verifiable state integrity of blockchain and combines it with a high-performance trading environment.  The core advantages are better transparency, tighter security, greater accuracy, reduced cost and more efficient trading. Building on Hyperledger Fabric allows Symbridge to have a decentralized validation network without sacrificing performance. Learn more about our validation network powered by Hyperledger Fabric. 

TradeAssets

TradeAssets is a digital platform for banks that automates the process of trade finance risk origination and distribution. It enables institutions to buy and sell bank risk assets while retaining some of the bilateral aspects of their current process. KrypC has helped TradeAssets implement a Hyperledger Fabric-based blockchain in its online portal for securing assets. The portal is now live and provides a single point of access for the sale and purchase of assets. Banks can communicate to a large ecosystem of connected institutions to efficiently match the appetite of sellers with buyers. The entire process is quick and convenient, and all communications are secured through the portal.

TradeAssets provides robust security, complete transparency, and immutable trust and consensus between all parties.

Ledger Leopard Uses Hyperledger Besu to Power a Scale-Up’s New Digital Approach to RTI Tracking

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

Most of the products we use and consume every day are transported on Returnable Transport Items (RTI). Durable and reusable, RTIs like crates, pallets and containers allow producers to move goods efficiently and sustainably. However, tracking RTIs is often a logistical nightmare. There are billions of palettes circling around the world, and trillions of total RTIs on the move. 

When Milou Klooster joined her family’s Netherlands-based smoked fish company, Vishandel Klooster, she soon discovered how much time, money, and energy her team was wasting on tracking RTIs. When she searched for a solution to this problem, she found there wasn’t any.

She resigned from the company and partnered with consultant Yves du Bois to develop a digital approach to the problem. Together, they founded RTI Blockchain. Their aim: a reliable app that connects all members of the supply chain together in one dashboard and provides a real time overview of the status of their RTIs.

Working with blockchain-as-a-service company Ledger Leopard, they developed the RTI Dashboard—a simple and reliable way to manage load carrier administration. Using blockchain technology, the RTI Dashboard gives poolers, suppliers, shippers, and receivers real time insights on their RTI data and enables them to share information privately and transparently. Every link in the supply chain is connected, and the interface is as intuitive as mobile banking.

When it came time to consider a platform, the Ledger Leopard team first considered Ethereum Liberty because it allows for private transactions. Then they considered Hyperledger Fabric. They also considered a combination of Ethereum and Hyperledger.

Ultimately, they chose Hyperledger Besu, an open source Ethereum client for developing enterprise applications that need secure, high-performance transaction processing in a private network.

One key goal was making sure the RTI Dashboard was as easy and intuitive as online banking. Users don’t need to know anything about blockchain to use it. Registration for all users is free. There is no subscription fee, no maintenance and support fees, no cost whatsoever for users. Senders pay per item they ship over the platform at a rate of 0.0005 euros per item.

Once a company registers in RTI Dashboard, they can invite their partners to join with a link. Once the partner clicks on the link, they’re invited to explore the platform and how it works, all at no charge.

RTI Blockchain suggests users start small. “Take one supplier and use RTI Dashboard for all transactions. Once they see what the system can do for them, they’re more willing to move their entire RTI administration process to the system,” says co-founder Yves du Bois.

Hyperledger worked with RTI Blockchain and Ledger Leopard on a case study that details the goals and approach for building this solution, the growing feature set that users are helping to shape and the next opportunities the start-up is eyeing for this dashboard. 

Read the full case study here. For more details, tune into the Wednesday, October 20, discussion with Olivier Rikken of Ledger Leopard on supply chain traceability.

Maintainers from four Hyperledger projects to serve as code contribution guides during AnitaB.org Grace Hopper Celebration

By Hyperledger Blog, Hyperledger Besu, Hyperledger Cactus, Hyperledger Indy, Hyperledger Labs

Hyperledger is once again sponsoring the annual AnitaB.org Grace Hopper Celebration as a way of supporting leaders and future women technologists in our global community. Hyperledger and the Linux Foundation are committed to supporting women-led initiatives centered around recruitment and engagement like AnitaB.org.

This year, Hyperledger is putting its resources behind Open Source Day (OSD), an all-day hackathon for participants of all skill levels to learn about open source while contributing to projects designed to solve real world problems. OSD will be held October 1 as part of this year’s Grace Hopper Celebrations (vGHC). 

During OSD, the women taking part will spend the day diving into the open source world to level up their skills and start contributing code. Participants will work in groups and with the mentors for hands-on learning, tailored to their experience level. 

Hyperledger is an official Open Source Partner Project for OSD and is teaming with maintainers from four Hyperledger projects to introduce participants to its diverse ecosystem. Maintainers from these projects will on hand as guides to both the Hyperledger technologies and the code contribution process:

  • Hyperledger Besu, an Ethereum client designed to be enterprise-friendly for both public and private permissioned network use cases;
  • Hyperledger Cactus, a blockchain integration tool designed to allow users to securely integrate different blockchains; 
  • Hyperledger Indy, a framework that provides tools, libraries, and reusable components for providing digital identities rooted on blockchains or other distributed ledgers; and
  • Firefly, a Hyperledger Lab, a multiparty system for enterprise data flows, powered by blockchain.

For each of these projects, the maintainers have compiled an array of pull requests or tasks that are tagged as “Good First Issues” that participants can tackle as their initial code contributions to Hyperledger. These triaged, non-documentation requests include everything from bug fixes to enhancements to security plug-ins. For those who want to challenge themselves or move deeper into a project, the Hyperledger Cactus list is broken down based on level of experience:

  • Level 100 – Introductory
  • Level 200 – Intermediate
  • Level 300 – Advanced
  • Level 400 – Expert

We want to thank our maintainers Anastasia Lalamentik (FireFly), Grace Hartley (Besu), Justin Florentine (Besu), Linlu Liu (FireFly), Nicko Guyer (FireFly), Peter Somogyvar (Cactus), Renata Toktar (Indy), and Tracy Kuhrt (Cactus) for offering their time and expertise to OSD. They will play a vital role in welcoming the Grace Hopper community into the world of open source and setting them up for success as contributors to Hyperledger and other projects.

#HyperledgerInterop: A Sampling of Production Cross-Platform Solutions and Deployments Built with Hyperledger Technologies

By Hyperledger Blog, Hyperledger Besu, Hyperledger Fabric, Hyperledger Sawtooth

The rapid pace of innovation in the development and deployment of blockchain technologies is creating more points of intersection for cross chain and cross application data and transaction flow. Fortunately, there is also a robust effort underway to deliver new approaches to ensuring that solutions work across platforms and protocols. Case in point: at the upcoming Hyperledger Global Forum, there will be 20 talks covering various aspects of blockchain interoperability and integration. 

Below, we take a look at a sampling of use cases where Hyperledger technologies are at play in solutions that are operating in or enabling cross-platform production deployments: 

Daml
Daml, a multi-party application platform created by Digital Asset, is widely used in distributed applications that deliver portability across a number of blockchain platforms, including Hyperledger frameworks: Besu, Fabric and Sawtooth. Recently, using Hyperledger Fabric, Ethereum and a traditional Postgres database, Digital Asset demonstrated platform interoperability and open sourced the code to help CBDCs (and other applications that need to integrate with CBDCs) interoperate, making the digital currencies compatible regardless of the underlying technology. The code for this CBDC use case is available on Git Hub. Read more and watch the demo here.

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 created media and user input 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 third party can verify the information on the public ledger to match the image and, if necessary, its accompanying data stored on the private ledger.

Project Starling

Project Starling was developed to help empower organizations to securely capture, store, and verify human history. Starling represents a ground-breaking methodology in the fight against the spread of misinformation and the looming threat of deep fakes by providing open-source tools. Starling uses the latest cryptographic methods and decentralized web protocols to meet the challenges of establishing trust in our most sensitive digital records.  

Jointly developed by teams at USC and Stanford, the Starling framework leverages multiple decentralized technologies including IPFS, GUN, Hyperledger Fabric, and Hedera Hashgraph throughout its process. For each piece of media captured, the framework is designed to store images on IPFS, using Filecoin, these image’s associated metadata is then stored in a permissioned Hyperledger Fabric network, securely protecting any sensitive information. For each media file, a hash of the information stored in Hyperledger Fabric is taken and recorded on the public Hedera network. By doing so, third parties are able to more readily trust the application owner and be assured no bad actor has falsified or modified results after the fact.
