Hyperledger-Powered Solutions Helping to Reshape Healthcare

By Hyperledger Blog, Healthcare, Hyperledger Fabric, Hyperledger Firefly

For decades, the healthcare industry has faced the challenge of juggling a huge (and growing) amount of patient, payer, provider and pharmaceutical data with managing accuracy, access, security and privacy. There has been continuous innovation and investment aimed at breaking down information silos and improving the efficiency and effectiveness of data reporting and sharing. Hyperledger technologies power an increasing number of the solutions that are taking on these challenges head on and creating new models for the industry.

Read on for a sampling of these Hyperledger-powered solutions and the ways they are helping to streamline a range of critical healthcare processes. And join the conversation using #HyperledgerHealth on social channels.

Avaneer Network

Founded by a consortium that includes Aetna, Anthem, Cigna, Cleveland Clinic, HCSC, IBM, The PNC Financial Services Group, Inc., and Sentara Healthcare, Avaneer Health has built a private, secure, and trusted technical healthcare network where stakeholders can collaborate to streamline and improve the healthcare experience while increasing administrative efficiency. The Avaneer Network leverages Hyperledger Fabric-based blockchain technologies to ensure privacy, security and content-based use of data. Participants connecting to the Avaneer Network have access to a range of solutions for securely transacting and administering healthcare and deploy innovative solutions that streamline processes. The first network participants, all founding members of the consortium, represent 80 million covered lives and 14 million annual patient visits.

IBM Digital Health Pass

IBM Digital Health Pass, built on Hyperledger Fabric, offers a multi-credential verifier that organizations can use to manage and execute their verification policies for COVID-19 and vaccination status in a way that balances the privacy of the individual with the requirements set by the organization and local health authorities. With IBM Digital Health Pass, organizations can verify multiple types of COVID-19 health credentials, such as Good Health Pass, IBM Digital Health Pass, Smart Health Card and EU Digital COVID Certificate. Privacy is central to the solution, where the verifier application minimizes the personal data that is ever displayed to the user through the execution of business rules and it never lets any personal data leave, or be stored in, the verifier app.

KrypC Pharmaceutical Delivery Supply Chain Solution

KrypC’s pharmaceutical supply chain solution uses Hyperledger Fabric to connect pharmaceutical manufacturers and carriers to collaborate on the safe delivery of drugs. The solution focuses on end-to-end traceability to provide an audit trail for the efficacy of drugs by capturing and verifying information such as the manufacturing date, location in transit, and more. With multiple handoffs across handling agents across continents, there is a crucial need for trusted, end-to-end visibility of pharmaceutical shipments, conditions, and documents. With this solution, Kypc leverages blockchain’s inherent ability to trace drug provenance and create an immutable record of the lifecycle of a drug and how it was handled to address the challenges the pharmaceutical industry faces, both in sourcing and distributing drugs.

Synaptic Health Alliance Decentralized Provider Data Directory

The Synaptic Health Alliance is a coalition of healthcare leaders working to solve their industry’s toughest problems through blockchain technology. Their objective is to create a blockchain-powered platform that enables a culture of innovation, removes friction and solves the shared challenges impacting constituents across health care today.

For their first application, they tackled the challenge of providing healthcare organizations with accurate provider demographic data. Today, healthcare organizations typically collect provider demographic data in separate IT systems maintained by each organization independently. This promotes vast inefficiencies and duplication of efforts (costing roughly $2.1 billion across the industry), while also potentially reducing data quality.

To solve this, Synaptic created a blockchain-based Decentralized Provider Data Directory leveraging Kaleido and the capabilities of Hyperledger FireFly. Through the power of blockchain, participants are now able to crowdsource provider demographics. Token economics incentivize the creation of accurate data, which can then be used by other providers to update their own records, reducing duplication of effort, streamlining administration, and saving money.

Ongoing activity in the space is driven by the very active Hyperledger Healthcare Special Interest Group (SIG), which unites healthcare professionals and technologists from around the world in advancing the state of the healthcare industry through the implementation of technology solutions using blockchain technologies in general, and the umbrella of Hyperledger frameworks and toolsets in specific. It includes subgroups focused on patients, payers and healthcare interoperability.

Hyperledger Lab Perun Adds Payment Channel for Cosmos Network

By the Perun community Blog, Hyperledger Labs

We are excited to announce that Perun, a Hyperledger Lab, has published the first version of the Perun-CosmWasm blockchain backend. For the first time, this enables Perun Channels on the Cosmos Network using the CosmWasm smart contract technology. For our first release, we focused on payment channel functionality on a single Cosmos blockchain. This paves the way to enabling the full potential of Perun on Cosmos in the future: atomic transactions with arbitrary transaction logic across multiple Cosmos blockchains.

Payment Channels on Cosmos Network

A payment channel is a construct that allows users to transfer and swap funds at low latency and nearly zero fees without a trusted intermediary. It allows users to massively scale their transaction capabilities without losing the trustless nature of blockchain technology.

Figure 1: Alice and Bob create an off-chain channel to interact.

In the future, Perun will support channels across multiple blockchains—for example, two Cosmos chains, or a Cosmos chain and an Ethereum chain. This will enable cross-chain applications based on channel technology.

With the addition of CosmWasm, the Perun framework now contains three backends (Ethereum, Polkadot, Cosmos). Blockchain-agnostic applications can be written and run within Perun channels. The used backend can be exchanged with another to enable identical contracts across multiple blockchains. The possibility to add further backends increases the modularity of the architecture of blockchain-agnostic applications.

About Perun

Perun, a Hyperledger Lab, is a joint DLT Layer-2 interoperability and scaling project contributed by Robert Bosch GmbH’s project “Economy of Things” and PolyCrypt. PolyCrypt is a spin-off of the Technical University of Darmstadt (TUDa).

If you want to learn more about the framework, please refer to the white paper and our last Hyperledger labs post or this Hyperledger presentation on Perun or reach out via our Discord channel. (New to Discord? Go here for more and to get signed up.)

Hyperledger Cactus: Release V1 on the Road to General Blockchain Integration

By Peter Somogyvari at Accenture and Takuma Takeuchi at Fujitsu Limited Blog, Hyperledger Cactus

Since its inception as a Hyperledger project almost two years ago, Hyperledger Cactus has come a long way. Today, the maintainers are excited to announce a version 1 release that supports many exciting integration applications and moves us in the direction of our “dream” modular architecture.

For creating a new token economy beyond financial and non-financial areas, blockchain interoperability has an essential role in interacting with multiple blockchains in various industries. But it is challenging to develop codes integrating with multiple blockchains because the SDKs provided by each blockchain for posting transactions or getting block data are entirely different. So, this community published a blockchain interoperability tool called “Hyperledger Cactus” to help engineers integrate multiple blockchains easily.

Hyperledger Cactus is a pluggable enterprise-grade framework for transacting multiple blockchains. This project aims to provide a decentralized, adaptable and secure integration between blockchains and various platforms. Cactus codes are composed of three types of parts. “Cactus Servers” provide abstracted APIs that can be uniformly called independent of each blockchain SDK’s format, and APIs that can use each blockchain SDK wrapped with the typescript-axios API format using Cactus API Server. “Business Logic Plugins” coordinate cross-blockchain business logic applications. “Ledger Connectors” facilitate connections to various blockchains, including all the blockchains of Graduated Hyperledger projects.

The Hyperledger Cactus v1 release includes the following modules:

Ledger Connectors – connectors to communicate with various blockchain platforms using multiple programming languages: (TypeScript and Python)
- Hyperledger Besu
- Hyperledger Fabric
- Hyperledger Indy
- Hyperledger Iroha
- Hyperledger Sawtooth
- Corda
- Go-Ethereum
- Quorum
- Xdai
Business Logic Plugin samples – the application integrates multiple blockchains:
- supply-chain-app: management application of supply chains process using Hyperledger Besu, Fabric, and Quorum
- carbon-accounting: carbon accounting application using Ethereum and Hyperledger Fabric
- discounted-cartrade: car ownership trading application using Ethereum currency, tokens on Hyperledger Fabric, and digital identity certification using Hyperledger Indy
- electricity-trade: automatic electricity payment application using Ethereum currency, whose events are triggered by electricity metering transactions on Hyperledger Sawtooth.
Keychain Plugins – A set of plugins for storing sensitive information in storage engines outside of Cactus. Currently, these plugins support AWS, GCP, Azure, and Hashicorp Vault
Support Libraries – Various utility libraries that simplify programming business logic plugins. These are great for setting up your applications and can even help your test automation, where the simulation of a new blockchain is required with the lowest possible resource usage.

As part of the continual effort to mitigate risks, the current 1.0.0 release is undergoing a a third-party security audit at the time of this writing.The process will take about 6 to 8 weeks to complete, but we are planning to keep the 1.0.0 API stability in place as dictated by the semantic versioning rules.

It’s effortless to try out Hyperledger Cactus today. We provide instructions for running a sample implementation of the Business Logic Plugins (service applications in Hyperledger Cactus architecture) that takes advantage of various blockchain platform features so you can evaluate Hyperledger Cactus on your PC.

It is even possible to set up a container with a supply chain example using a single command-line command! Here is a link to this example. We encourage you to see for yourself how easy it can be to get started with blockchain integration using Hyperledger Cactus.

Our long-term architectural goals for Hyperledger Cactus are to offer a flexible, modular system that allows users to configure blockchain integration systems to fit their needs exactly. We want users to reuse code as much as possible while still avoiding code bloat and duplication in the features. In future releases, we will actively cooperate with other Interoperability infrastructures besides Cactus, and we hope to provide more user-friendly tools by incorporating more features.

(Note: for more on the Hyperledger interoperability ecosystem, read Why is Interoperability Needed?)

We would love to welcome you into the Hyperledger Cactus community. Unlike our project namesake, we are not prickly! Whether you want to contribute or are just interested in using Cactus, we would love to connect.

It’s easy to get in touch with us! The simplest way is to reach out on the Hyperledger Cactus Discord channel. (New to Discord? Go here for more and to get signed up.) We have pair programming sessions set up for new contributors and users almost daily (please check the Hyperledger calendar), so we would be more than happy to help if you would like to contribute or want help getting up and running. We look forward to hearing from you!

Interoperability in the Open Source community

By Tim Spring, Indicio Blog, Healthcare, Hyperledger Aries, Hyperledger Indy, Identity

Without interoperability, you wouldn’t be able to read this article. Websites, computers, and servers must be able to recognize and share information with each other, and shared standards and protocols allow them to do so, thereby giving us the web. On a smaller scale, companies have their own intranets, and, on the smallest scale, you might have your own private thumb drive for personal documents that can interact with whatever machines you typically work on.

Interoperability is not a technological given or an inexorable process. It is a choice that needs to be actively made, and it can sometimes take considerable effort to make work. Think of electronic health care records and the years it has taken to make it easier for a patient to access their health data, something originally provisioned in a 2000 Privacy Rule to the Health Insurance Portability and Accountability Act (HIPAA) of 1996.

Crises, however, can accelerate the slog to technological convergence—and that’s precisely what we’ve seen as a result of the global COVID-19 pandemic. In April 2021, a data-sharing provision of the 21st Century Cures Act came into effect: Patients must be able to have direct digital access to eight categories of clinical notes in an electronic health record, notably—given the need for COVID testing—lab test results.

Cometh the legislation, cometh the tech. Indicio and SITA had already been working on a decentralized, verifiable credential solution to integrate passenger health data with air travel in a privacy-preserving way. Built on Hyperledger Indy and Hyperledger Aries, the technology solved the problem of patient privacy by eliminating the need for a centralizing party to store patient data in order to facilitate verification.

With the Cures Act provision, there was now no obstacle to passengers in the US accessing their COVID test data directly from a Health Information Exchange in the form of a digital credential. They could use this credential to prove their test status without having to share personal information. In situations where it was important to know which test they had taken and when, they could choose to share this information with a verifier, such as the border control or health agency of the country they were visiting.

This solution is now known as the Cardea Project. Successfully trialed in Aruba, its codebase has been donated to Linux Foundation Public Health as an open source solution for sharing health data through verifiable digital credentials. It has an active community group, led by Indicio and Shatzkin Systems, that is working on expanding its features and, critically, its interoperability.

To do this, Cardea launched a hackathon for interoperability— dubbed an “Interop-a-thon”— in September 2021. The goal was to get companies using Aries agents to test those agents against a reference implementation of Cardea and each other. Over a half day, SITA, Liquid Avatar, IdRamp, GlobalID, Canadian Credentials Network, and Network Synergies all successfully interoperated. That’s the headline; the story, however, is that it took work to make this happen—it was an exercise in uncovering glitches, unexpected problems, and overcoming them. That’s what made the Interop-a-thon so valuable for all the participants—and that’s why Cardea is holding a second Interop-a-thon on March 17.

This time, in addition to agent testing, Cardea is going to field “out-of-band” invitations (a critical change coming to Hyperledger Aries at the end of March) and a simple reference implementation of machine readable governance (a way of adding governance rules at the agent level, thereby making governance portable and available offline).

Participants see interop-a-thons as a testing ground for interoperability, and therefore a way to ensure that the products and services they are building have the capacity to scale. This is a critical step toward achieving a network of networks effect. Not surprisingly, the number of participants signed up for the next Interop-a-thon is much greater than the first.

For Cardea, there are more and bigger trials on the way. And with each solution delivered, the scope for expansion becomes greater. If we can successfully implement a system for incorporating health data in travel, what about all the other clinical notes described by the Cures Act? What’s the roadmap to creating a decentralized health record?

This is the perfect challenge for an open source community to solve. And by testing the solution through an interop-a-thon, we can figure out how to make the many function as one.

If you want to learn about interoperability first hand, I highly encourage you to watch the video of their last Interopathon here: https://www.youtube.com/watch?v=KVywPPLhG0U.

Performance SandBox, a new Hyperledger Lab, is a test ground for blockchain performance research

By Sam Yuan, IBM Blog, Hyperledger Labs

Meet Performance SandBox, a new Hyperledger Lab for testing new research to boost performance of blockchain platforms. This is an open source effort and you’re welcome to get involved by checking out the lab’s repository or by joining the monthly Performance and Scale Working Group calls.

What is Performance SandBox?

A new addition to Hyperledger Labs, the Performance Sandbox is a testing environment for Hyperledger projects performance research usage.

As the picture above shows, the Performance Sandbox uses Kubernetes as its infrastructure and is integrated with monitoring and open tracing (or say open telemetry).

– It supports users deploying a target network such as a test-network, also known as a SUT (system under test), for asset transform for Hyperledger Fabric

– It supports any traffic generator such as Tape, a light-weight tool to test performance of Hyperledger Fabric, that keeps sending traffic to the target network/SUT.

How does the Performance Sandbox work?

Performance researchers are able to use this lab to do research with the steps below:

1. Start the sandbox with Kurbenetes integrated with monitoring and open telemetry

2. Deploy the SUT onto the Kubernetes infrastructure.

3. Start the traffic generator to keep sending traffic to SUT

4. Monitor and analyze test results from the dashboard/open telemetry results.

5. Changes local source code (e.g., Hyperledger Fabric), make local docker image and redeploy the SUT.

It will extend the existing paper published by the PSWG with monitoring and open telemetry. As the right side in the above figure shows, we can see the performance test model published previously by PSWG, with SUT, traffic generator and observers.

Flexible design

– Migration from Kind to other Kubernetes platforms: In this lab, we use Kubernetes as infrastructure, hence it is easy to migrate to any other Kubernetes-based infrastructure.

– Use with blockchain systems other than Hyperledger Fabric: So far, the PoC and demos have been based on Hyperledger Fabric. However, as the orange area shows, the blockchain system can be replaced with any kind of blockchain system.

– Traffic generator: So far this has been deployed as a demo with Tape, as it is a Kubernetes development. It can be replaced with Hyperledger Caliper or Jmeter. Tape is a sample performance tool for Hyperledger Fabric without an SDK (close to the blockchain network itself). Caliper is based on the Hyperledger Fabric SDK (closer to the application level). You may need to use Jmeter to create traffic for end-to-end performance research assuming you expose the RESTFUL endpoint to the end user

– Size of SUT: you are able to scale the size for SUT, as it is a blockchain based on Kubernetes.

Technological details

Read on for technological details around three topics: deploying monitoring tools with operator, traffic generator, and dashboard.

Deploying monitoring tools with operator

In the Performance Sandbox, we used operator technology (refer to operator capablities) to make monitoring systems work with Auto Scaling and Auto Tuning.

For example:

When a blockchain node (e.g., Hyperledger Fabric peer) has been deployed, the Kubernetes operator will help make a connection between the blockchain node (as service/pod) and monitoring system (as Prometheus, Jaeger, etc.) to automatically tune the operator framework to a certain workload pattern.

Ideally, users are able to deploy any size of nodes (e.g., number of peers) for the SUT without spending too much effort on configuration.

Meanwhile, the operator is able to deploy across Kubernetes clusters, making it easy to migrate to any specific cluster.

Traffic generator

In most cases, performance is evaluated by TPS (transactions per second). However, there are different scenarios for the “transaction.”

Let’s assume we have an application server that receives a restful API to support Alice and Bob, sending traffic from the application GUI/mobile app. Normally, the application will connect with the blockchain network. Generally speaking, the application depends on the SDK and SDK relay on network protocols such as GRPC.

On the left side of the figure above, the three arrows indicate three different levels of traffic.

– At the end user level, indicated by the green arrows, an application receives a business transaction and returns it. Total time spent includes application logic and SDK level duration.

– At the SDK level, indicated by the blue arrows, an SDK receives a business transaction and returns it. Total time spent includes SDK logic and communication level duration.

– At the communication level, indicated by the red arrows, the total time involves packaging business transactions following communication protocol and sending them to the blockchain network.

Hence, we can see from the open tracing span, the green line means the total time starts when the application received the user’s request and ends with application return. Then the blue line appears as SDK processing time. Then the gRPC time reflects the duration for a gRPC to send and receive a response back from the blockchain network.

Ideally, those TPS are nearly the same and you either focus on the application side or blockchain side. However, we’d better have tools on hand for handling some edge cases such as SDK overhead, bad application logic, etc. As on right side:

1. Indicates application processing time before transaction reach at SDK and ready for send to blockchain network.

2. Indicates SDK starts processing the transaction and time spent before network communication happens.

3. Indicates SDK received a result for network communication, and time spent before SDK return.

4. Indicates application processing time before transaction return back to end users from SDK result.

{Note: If you’re interested in blockchain performance testing tools, you can also check out Hyperledger Caliper.}

Dashboard

In the Performance Sandbox, we used a dashboard for system monitoring. In most cases, we analyze TPS as a collection for data drawn as a histogram.

For example, we are able to draw down Transaction Throughput based on timeline into a figure (refer to performance metric). However, as the blockchain is based on crypto service, which relays CPU resources and consensus, that relays bandwidth.

With the dashboard, we are able to collect both blockchain matrix and system matrix at the same time, by integrating different matrices together, identifying limitations/bottlenecks in a visual way.

Assuming bandwidth is a bottleneck for the current Performance Sandbox environment, we can see the CPU/time left with some capabilities at all rounds of testing. Each time when the transaction throughput reaches a specific value, network bandwidth will be used up.

What’s Next

Now, let’s go back to the goal of this new Hyperledger Lab: to provide a sandbox to make performance research usage easier. To see what’s next:

Blockchain	Deployment	Communication Level Traffic	SDK Level Traffic	User Level Traffic	Dashboard Metrics
Hyperledger Fabric	test-network-k8s (WIP, as application and couchdb)	Tape	Hyperledger Caliper (tbd)	jmeter (tbd)	to be completed
Hyperledger Fabric	Minifab (tbd)	…	…	…	…
Hyperledger Fabric	Hyperledger Bevel (tbd)	…	…	…	…
Hyperledger Fabric	Hyperledger Cello (tbd)	…	…	…	…

Taking Hyperledger Fabric as a sample: we need to support different ways to deploy Hyperledger Fabric as a test network, including Kubernetes, Minifab, Hyperledger Bevel, Hyperledger Cello, etc.

Meanwhile, to fully support traffic generators, we need to go through different levels of traffic generators and complete a dashboard.

#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 O₂reduced 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 Challenge 2022 is all set!

By Global Hyperledger Community Blog, Regional Chapter

Collaborating to overcome today’s and tomorrow’s challenges

Website | Wiki

What is it?

The Hyperledger community is launching the Hyperledger Challenge to harness the power of communities to ideate, develop, and launch innovative solutions developed using open source technologies. Any innovation that advances the current state-of-the-art of enterprise-grade distributed ledger technologies leveraging one or more Hyperledger projects is eligible for the Hyperledger Challenge.

When is it?

The Challenge will feature three rounds, called “Ideate,” “Prototype” and “Launch,” to develop innovations from ideas to sustainable solutions in the manner of months. Innovators competing in the challenges will have access to training, mentors and the Hyperledger community to support the development of their solution. The Hyperledger community is committed to be a driving force to incorporating Diversity, Civility, and Inclusion into programs. Innovators are greatly encouraged to consider diversity and inclusion when developing their teams.

The ideation phase was kick-started on 18th January. Submissions are welcome until 1st March 2022. Do reach out if you have more questions on timelines and deadlines.

Look out for the updated timelines information at https://wiki.hyperledger.org/display/events/Hyperledger+Challenge+2022.

Who is it for?

The Hyperledger Foundation hosts a number of enterprise-grade blockchain software projects. The projects are conceived and built by the developer community for vendors, end user organisations, service providers, start-ups, academics and others to use to build and deploy blockchain networks or commercial solutions. This challenge will feature:

A network of support for future innovators to advance the current state-of-the art of enterprise-grade distributed ledger technologies.
A place to partner with similar entrepreneurs, to connect with leading experts, to learn, to scale up, and to achieve real impact in the world.
