Recap: Hyperledger Intros Blockchain at HIMSS

By Blog, Healthcare

The Hyperledger team recently attended HIMSS in Orlando, Florida. More than 40,000+ people joined us in learning more about the role of technology and IT in healthcare. Hyperledger was there to lend a vendor-neutral, “open source software-first” voice to the rapidly-advancing discussion in healthcare about how to leverage blockchain technologies. Really this meant we were there to listen, facilitate introductions, educate when we had a specific point of view and, ultimately, advance the readiness of healthcare professionals and organizations to get started with blockchain.

HIMSS kicked off with a keynote speech by IBM’s CEO, Ginni Rometty. Ginni shared her belief that to be successful in this new era of computing, companies will need to have clear strategies on AI, cloud and big data. She led on to say that within all of that, transparency, accountability and trust will become even more important, if not demanded. Ginny then spoke to blockchain, its affect on the industry and mentioned Hyperledger as a consortium leading the governance and community development around blockchain technologies for business.

Hyperledger set up shop in the Innovation Zone at the enormous Orange County Convention Center. Those who visited us at our kiosk wanted to know what blockchain was, Hyperledger’s role in the market, how blockchain could be applied to healthcare and what some of the opportunities or challenges might be.  

Across the way from us in the Innovation Zone were our friends at Hashed Health, a member company focused on accelerating blockchain and distributed ledger technologies in healthcare. They brought along a demo of a provider directory that they built using Hyperledger Fabric, one of the three blockchain frameworks in incubation at Hyperledger, and when attendees wanted a solid example of how blockchain worked, we sent them their way. A few other members companies that attended included Accenture, Gem, and IBM.

A major focal point for Hyperledger at HIMSS was IEEE’s sold out Rock Stars of Blockchain event. Morning sessions grounded the 200+ attendees with the basics of blockchain tech and it’s applicability to healthcare. Speakers hit themes like interoperability, breaking down silos, increasing patient control while streamlining expensive and time consuming processes, providing holistic, longitudinal views to health.

After a great introduction from Conduent’s Tamara StClaire on the basics of blockchain and its promise in healthcare, Abbie Barbir from Aetna gave an excellent talk about the use cases for blockchain in healthcare. Mr Barbir shared this conceptualization of a blockchain-based ID vetting system.

Next, Dr. Jon White and Steve Posnack from ONC shared the work their team has been doing to support and stimulate the adoption of EHR and lately on exploring the uses of blockchain in healthcare. They of course referenced last year’s Blockchain Challenge on ONC Lab. And one really can’t talk about the ONC challenge without discussing the winning MedRec paper.

At lunch, Hyperledger sponsored a hands-on workshop for healthcare professionals charged with spearheading their organization’s lab, PoC and pilot use of blockchain technology. The lunch and learn used the recent Hyperledger Healthcare working group survey as the jumping off point to explore popular industry use cases.

Much more participation than presentation, the ~30 participants included physicians, vendors, payers, consultants and other HC pros. Over the 90-minutes, participants worked at their tables on MVPs for popular healthcare blockchain use cases and discussed the roadblocks that might prevent a PoC. For a full output report, and to join the discussion, check out the Hyperledger Healthcare page and join the healthcare working group email list.

After lunch, Hyperledger Executive Director, Brian Behlendorf moderated a panel with Cerner, IBM and IEEE on the impact of blockchain on connected health. Panelists shared what each are doing with blockchain technology for healthcare and general thoughts on the subject.

They then covered confidentiality and patient privacy, exploring such questions as how to deal with private data in a blockchain, how blockchain will change the patient experience, and what regulatory hurdles must be overcome.

Some panelists expressed confidence that blockchain technology has the features to transform healthcare, much like other technologies before. Like other approaches, what must not be overlooked with blockchain are all the other environmental factors in healthcare, such as regulation, business models and having a complete architectural design. Others were more bullish about the role blockchain will play to place patients in more control over their data and their healthcare experience.

After the panel, Brian and Gem CEO, Micah Winkelspecht held a fireside chat, exploring some of the key questions that had emerged throughout the day.


Dr. John Mattison from Hyperledger member, Kaiser Permanente closed the day out with a talk on Defining a Minimum Viable Product (MVP) with Blockchain in Healthcare: Challenges and opportunities.

We are very excited that blockchain conversations in healthcare are picking up, we’re learning more and more about POCs and pilots and there is a lot of interest in Hyperledger. If you’re interested in how blockchain can work in healthcare, want to join the discussion further, or have specific questions about Hyperledger, we encourage you to join our Healthcare Working Group here: https://www.hyperledger.org/industries/healthcare.

Our Incubator’s First Graduate: Hyperledger Fabric

By Blog, Hyperledger Fabric

I’m thrilled to announce that yesterday, Hyperledger’s Technical Steering Committee (TSC) agreed to grant the project team’s request to advance the project’s status from Incubation to Active. As a reminder, we see Hyperledger as an “umbrella” for software developer communities building open source blockchain and related technologies. Fabric falls under that umbrella and is the first of the five Incubator projects to graduate. While Hyperledger Fabric has not yet reached its v1.0 release, the TSC members unanimously agreed that the project has satisfied all of the Incubation Exit Criteria.

The exit criteria by which projects are evaluated in order to graduate from Incubation include legal compliance, community support, test coverage and continuous integration support, documentation, architectural alignment, published releases, and infrastructure support for such things as requirements and defect tracking, code reviews, continuous integration testing and more.

One of the most important of these criteria is the community support criteria. The most successful and sustainable open source projects grow out of a diverse community of contributors, where the loss of any one individual or company can be compensated by the community as a whole. Hyperledger The TSC members agreed that Fabric had made significant progress towards that diversity goal, and given the trajectory, agreed that the criteria was satisfied.

IBM contributed the codebase that, in part, became the basis of the Hyperledger Fabric Incubator. In the year since the project entered incubation, the diversity of contributors on Fabric-related projects has grown from nearly no diversity of contributors to 45% of the contributors – representing individual contributors or developers working for one of nineteen other companies, be they exchanges, banks, large ISVs or start-ups. The project’s 10 maintainers – those individuals tasked with leading the project’s development – represent three different companies and two individual contributors. Hyperledger Fabric has also grown in terms of sub-projects contributed by other community members such as London Stock Exchange, DTCC, Fujitsu, and others. In my experience, few open source projects achieve that level of diversity in so little time.

Hyperledger Fabric has published two releases, the latest of which was their v0.6 release in the fall of 2016. The team is working on finalizing the development of the v1.0-alpha release, which they hope to publish this month.

This is a huge step for the Hyperledger community. The graduation of Fabric represents a milestone for the Hyperledger community as a whole, and I’m eager to see the other projects follow suit. As always, we encourage developers to join our efforts on Fabric, as well as other projects, via github, Rocket.Chat the wiki or the mailing lists.

Hyperledger’s Monthly Technical Update

By Blog, Hyperledger Cello, Hyperledger Chaintool, Hyperledger Explorer, Hyperledger Fabric, Hyperledger Iroha, Hyperledger Sawtooth

As our incubated projects continue to mature, we’d like to update the community monthly on the progress we make. Below are updates on Blockchain Explorer, Cello, Fabric, Sawtooth Lake and Iroha during February.

Blockchain Explorer

We completed the architecture review with the community and incorporated the feedback into the design document. The design document was posted on the “blockchain-explorer” channel on Rocket.Chat. We plan to upload this document to the Hyperledger wiki so that it is permanently available for anyone to review. We are continuing our work to make Explorer compatible with the Fabric 1.0 project.

Sawtooth Lake

New design updates were presented at the Hyperledger hackfest on Feb 1-2 and other Hyperledger forums. Parallel execution and new language support resounded well with the community. In the next month, we will begin work on new demonstration networks exhibiting some of the use cases prototyped using Sawtooth Lake.

Fabric

Fabric continues to press forward to wrapping up feature development for the 1.0 release. The team is preparing a version 1.0 preview initially, followed by an -alpha release by the end of February.

We’ve been bolstering our test frameworks with integration testing that had been developed by IBM for its offerings. We have also been taking a close look at improving documentation to make it more user and application-developer focused.

We had some interesting discussions with the Sawtooth team on integrating PoET into Fabric at the bi-monthly hackfest, which we hope to begin pursuing in the near term and we also continued working with the Sorimitsu team in aligning APIs.

Hyperledger Fabric played a prominent role in the largest blockchain hackathon to date, held in Groningen, Netherlands, Feb 10-12. 55 teams competed in five tracks and two of the five winning teams based their solution on Hyperledger Fabric. The other winning teams used Ethereum or Factom. Roughly half of the 55 teams were also using Hyperledger Fabric. It really was an exciting event and bodes well for the upcoming hackathon in Shanghai in March.

Cello

There are lots of discussions on the Rocket.Chat channel, mostly on documentations and deployment topics. Several Jira tasks were created as the feature roadmap, including refining documentation, supporting fabric 1.0 and supporting other blockchain platforms. We implemented the new dashboard configurations and refined the front-end code. Several deployment enhancement/patch sets are in the works to make Cello more stable.

Iroha

The API has been fixed and currently we are working on porting all the protobuf code to flatbuffers. There are several bugs/memory leaks with flatbuffers still, so we have been working with their project to fix these. We have also been working on getting flatbuffers working with grpc.

We are building a database for flatbuffers, iroha-ametsuchi. Anyone interested in working on it should take a look at the repository: https://github.com/hyperledger/iroha-ametsuchi

At the Hyperledger hackfest in San Francisco, we had an interesting discussion with IBM, where we outlined some ideas for creating inter-ledger transactions between Iroha and Fabric. If anyone in the community is interested in working on this together with us, please tell us on Rocket.Chat/gitter/github issue (https://github.com/hyperledger/iroha/issues/159).

That’s it for the updates! We encourage developers to join our efforts on these projects and help us shape the future of blockchain.

Developer Showcase Series: Judy Priest, Engineer, Cisco

By Blog

The Hyperledger community is comprised of developers and technical leaders from around the globe who are working together to change the world with blockchain technologies. This new blog series highlights the work and motivations of developers, users and researchers collaborating on Hyperledger’s incubated projects to build blockchain frameworks and platforms in an open and collaborative manner. Below is our first interview with Judy Priest who is an engineer at Cisco working on blockchain.

Let’s get to it…

Give a bit of background on what you’re working on and what made you want to get into blockchain?

Judy Priest, Engineer, Cisco

When I first started getting into blockchain, 99% of the published content was around Bitcoin, and 95% of the use cases involved some type of cryptocurrency. As a technologist, I had an appreciation for blockchain as a technology, but I didn’t have much interest in the typical financial transaction use cases.  However, I was fascinated by several of the other novel use cases that blockchain could enable.

Cisco is a long time member of The Linux Foundation and highly vested in the open source community. I attended the very first Hyperledger Project meeting, and we talked about the importance of creating an enterprise class solution based on blockchain that could span across multiple industries. We talked about the different use cases across supply chain, Internet of Things (IoT), healthcare, identity, and tracking and trading of digital and physical assets. These are all areas where Cisco is driving our digitization strategy, and markets that are important to our customers, partners, and suppliers. The dots were starting to connect on the revolutionary and truly disruptive potential of blockchain to transform businesses.

Can you sum up your experience with Hyperledger, thus far?

With any nascent technology, the global experts are rarely all inside one single company or university. Being a member of Hyperledger has given me access to an amazing intellectual collective, brought together in a genuinely collaborative community and cooperative development environment. If you look at blockchain long enough, you’ll soon realize that there isn’t a one-size-fits-all solution for all those different markets and applications. We came in with different ideas and eventually got to the point of defining frameworks for modular, configurable, and composable architectures, based on specific use cases that defined those particular requirements.

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

In the next year, I’d like to see this become more plug and play. Hyperledger can do the heavy lifting (e.g., code quality, documentation) so new developers can take the various components and spend less time debugging the codebase, and spend more time customizing a unique blockchain for their needs.

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

My advice for anyone interested in getting started working on blockchain – start with your business use case. If you don’t start there, you should expect a lot of mental spirals. As many experienced technologists will tell you, you need to fall in love with the problem you are solving, not the technology or the particular “hammer” you have available. If there is no pain point and a simpler solution already exists or is sufficient, then you should question whether a blockchain adds value. For many problems blockchain is not the right answer, but for some problems it is a transformative solution.

Gain your domain expertise early, dive into the codebase and start looking at what transaction layer requirements you have for your application. What security features, policy management, and infrastructure is required to support it?

When a technology has such wide cross-industry impact, it’s not a question of `if’ but a matter of “when” and “where”. As the poet Ovid said, “If you are not ready today, you will be even less so tomorrow.”

Are you building something cool on top of Hyperledger? Tell us about it – we’d love to feature your work. You can email pr@hyperledger.org, if so. You can also plug into the Hyperledger Community at github, Rocket.Chat, the wiki or our mailing list.

Recap: Dutch Blockchain Hackathon

By Blog

Guest post: Chris Ferris, Head of Hyperledger Technical Steering Committee 

I had a really great time this past weekend at the Dutch Blockchain Hackathon. I had been invited to serve as a “super accelerator”, a judging role I’ll explain in a bit.

This event was billed as the worlds largest blockchain hackathon to date. It was certainly impressive in its size! There were 55 teams of 5-6 participants competing in 5 solution domain tracks (Identity, Pensions, Energy, Reinventing Government, and Entrepreneurship and Trade). Microsoft and IBM were the Technology Sponsors of the event. Interestingly, the teams were roughly evenly divided between use of Ethereum and Hyperledger Fabric in their hacks. One team even tried to use Fabric v1.0 level code however, the nature of their hack involved a function still missing from the Node.js SDK, so they reverted to the Fabric v0.6 stable release.

One of the key themes of the event was that it was intended to “accelerate” winning teams through the next stages of realizing their vision – this is where the role of “super accelerator” came in. As a “super accelerator” we were to help the winning teams with connections, insights and guidance as they sought to continue development of their solution. I had offered to help any of the teams in establishing open source governance and community building insights for their projects, and for the winning teams using Hyperledger projects, any technical expertise and guidance.

The winning teams in the Identity and Entrepreneur track both used Hyperledger Fabric in their solutions. The Identity track winning team had a very novel approach to identity rehabilitation for refugees. The Entrepreneur track focused their winning solution on a uniquely Dutch problem pertaining to freelance contractors tax and pension allocation that is mandated by a new law.

Of course, there were plenty of great ideas being implemented by non-winning teams. Lots of world-changing ideas around green energy, identity and reinventing government. The energy and excitement at the event was inspiring. I’ll leave you with a taste in a video clip assembled by the organizers.

 

 

Given the excitement, innovation and energy at this event, I a really looking forward to the Hyperleger Hackathon in Shanghai next month!

Hyperledger Meetups – Get Involved in 2017!

By Blog

The Hyperledger meetup scene continues to thrive in 2017. We now have 9,134 members across 38 different meetup groups all around the world! We have our amazing community to thank for this growth.

Most recently, we hosted a meetup in Seoul, South Korea. 50 people attended from financial institutions like Mirae Asset and Shinyoung Securities, universities including Korea, Yonsei, and Hongik, as well as Hyperledger members like Coinplug, Samsung SDS and Koscom. There were also a few startups in attendance. The content was introductory and focused on Hyperledger Fabric. We’re now planning a meetup in Seoul on February 23 that will cover more general blockchain information, key players, as well as additional information on how Hyperledger fits into the market.


On January 17 we held our second Hyperledger Hong Kong meetup. Around 50 people attended, from financial institutions such as HSBC, Bloomberg and Standard Chartered Bank, to consultants including Ernst & Young and Deloitte, and Fintechs like ANX International.

Attendees were updated on exciting developments and activities in Hyperledger in Asia Pacific and Greater China, by Hyperledger Asia Pacific VP, Julian Gordon, and for Hong Kong by IBM’s Solution Industry Executive, Daniel Leung. John Wolpert, IBM’s Blockchain Offerings Director, led an in-depth discussion and Q&A on Hyperledger Fabric. The meetup was organized by Jen Advisors and held at Infiniti Lab.

We also hosted a Hyperledger meetup in Shenzhen, China on January 7. The meetup was organized by IPA (Investment and Promotion Administration, Futian District), FISCO (Financial Blockchain Shenzhen Consortium), Energy Blockchain Labs, IBM and Huawei. More than 250 attendees from 40+ different organizations came to sit in on both morning and afternoon sessions that covered the basics of blockchain technology, its application in financial services and technical discussions on Hyperledger.

Finally, there is a Hyperledger Hackathon planned for March 10 & 11th in Shanghai. It will include an overview on Hyperledger, chaincode development, and blockchain use case discussion.

Are you thinking of starting a Hyperledger meetup?  We strongly encourage and support the community in starting their own events, but there are a few things that should be considered beforehand. Please visit our Wiki to learn more first: https://wiki.hyperledger.org/community/meetups

Event Recap: Blockchain Masterminds Unite at Hyperledger Hackfest

By Blog

Guest post: Hanna Zubko, IntellectEU

Last week, Blockchain masterminds gathered for three events in the Bay Area:  Blockchain Protocol Analysis & Security Engineering Conference, CoinDesk’s Construct Conference, and Hyperledger’s Hackfest. All the events demonstrated that blockchain technology is becoming more mature and forming an emerging industry of startups and enterprise players.

On January 29-30, Stanford University hosted a deeply scientific conference on the security and systemic risks in blockchain protocols through the use of formal methods, empirical analysis, and risk models. Brilliant presentations on modern trends in consensus algorithms and communication protocols ensued open conversations among cryptographers representing various distributed ledgers. The conference succeeded to foster multidisciplinary collaboration among practitioners and researchers. Among the participants, companies presenting various efforts built on top of Hyperledger’s technology included HACERA, Skuchain, and IntellectEU. HACERA was presented at the second part of the talk  “Permissioning Your Blockchain: How to Overlay Hyperledger Fabric with a Fully Workable System Tapestry” at the event.

After an unusually warm weekend in San Francisco, a group of 350 technical blockchain experts headed to the Innovation Hangar. At the invite-only CoinDesk’s Construct Conference, participants heard the latest updates from CTOs of leading Blockchain initiatives, saw live product demos, and were able to install environments for protocols and projects that were new to some.

Hyperledger frameworks including Fabric, Sawtooth Lake, and Iroha had dedicated sessions presented by Chris Ferris, Mic Bowman and Makoto Takemiya, respectively. Brian Behlendorf, Executive Director of Hyperledger, delivered an update on the “Modular Umbrella Approach,” which included new efforts like Cello, and existing projects like Chaintool and Blockchain Explorer. Everyone that was interested in Hyperledger Fabric could witness a trading marbles demo in a separate dedicated pavilion.


While those events were a real treat for all Blockchain professionals, the Hyperledger Hackfest was the cherry-on-top. It gathered 80 Hyperledger enthusiasts and core developers at the Presidio on February 1-2. Both days were filled with project activities, updates, and work group meetings on coding and support. During the Hackfest, Iroha and IBM even announced their collaboration. The Hackfest featured two working groups: Architecture WG and Identity WG. The highlight had to be a presentation that introduced an application framework designed to simplify and expedite the creation of Hyperledger blockchain applications with additional business logic on top often referred to as “smart contracts” – Fabric Composer.

The consensus for all the three events is that Blockchain is here to stay. While 2016 was named the year of Proof of Concept, 2017 promises to be a year of Pilot. The Blockchain ecosystem across companies and industries unites efforts to address scalability and privacy challenges. It is acclaimed that the Hyperledger community plays a notable role in this game.

Hyperledger Says Hello to Cello

By Blog

Today, we’re excited to welcome a new project to Hyperledger, Cello. Cello is a toolkit for deploying a Blockchain-as-a-Service, that reduces the effort required for creating, managing, and terminating blockchains. Hyperledger serves as an “umbrella” for software developer communities building open source blockchain and related technologies, and as such, Cello joins many other efforts including Fabric, Sawtooth Lake, Blockchain Explorer, and Iroha.

What is Cello?

Cello aims to bring the on-demand “as-a-service” deployment model to the blockchain ecosystem, to provide a multi-tenant chain service efficiently and automatically, on top of various infrastructure, e.g., baremetal, virtual machine, and more container platforms.

With Cello, operators can create and manage multiple blockchains in a pool through a dashboard, at the same time users (typically the chaincode developers) can obtain blockchains instantly with a single request, as illustrated in the figure below.

Cello will plan to support existing and further Hyperledger blockchain platforms including Fabric, Sawtooth Lake, Iroha, and more. We have been evaluating Cello for several environments, e.g., Cello in a POWER-based Cloud has supported thousands of chains for nearly a year.
“Cello will definitely welcome potential collaborations with other important projects, to achieve another open-source success”, said by the initial project proposer, Baohua Yang.

Why Cello?

The Hyperledger community and by extension, The Linux Foundation, has initialized several projects (e.g., Fabric, Sawtooth Lake and Iroha) for the Decentralized Ledger Technology (DLT) ecosystems. Those projects provide various ledger implementations targeting performance, stability, permissions, scalability, etc. Cello hopes to help build the community by providing the blockchain service functionality and attracting more contributors to Hyperledger.

Today, to boot a chain, developers need to adopt the installation scripts, e.g., docker-compose scripts in Fabric. If multiple tenants requires to obtain separate chains at the same time, they have to modify the scripts carefully and create these chains manually. This procedure is time consuming, and even worse, leads to possible misconfigurations.

Take Hyperledger Fabric, for example, currently, the solution to create a Hyperledger Fabric chain includes:

  • Manual installation of each peer node on different servers. This requires much effort and is error prone.
  • Setup scripts (e.g., Docker-Compose) to start a fabric network. This requires a specific server configuration, which makes it hard to share resources and dynamically create multiple chains.

Cello solves these problems in a different way, by maintaining a pool of chains automatically. Users will get chains with various configurations instantly, while operators can dynamically scale the physical resources through a dashboard.

The Hyperledger community now has projects of SDK, blockchain-explorer and chaintool. Cello is a great complement. For example, Cello can boot a blockchain with blockchain-explorer as the dashboard, with SDK and chaintool as the interface to operate chaincode.

Cello’s Architecture

Cello leverages the Docker APIs to manage the blockchain clusters in remote hosts, including physical servers and virtual machines. Hence Cello can be easily deployed to Cloud environments that provide virtual machines on demand.

The design architecture is as follows:

  • Orchestration Engine: Core to handle resource management and workload scheduling, which is mainly implemented in Python;
  • Dashboard: Operational interface, implemented with JavaScript;
  • Restful Server: Operational interface, which is implemented with Python;
  • Drivers: Currently we utilize Docker API lib, to support native host and Swarm cluster The driver layer is designed to be pluggable to support more types in future;
  • Tools: We have also designed several tools to handle tasks like monitoring and logging, which are mainly implemented in Golang. However, the framework is pluggable, hence we can also integrate existing open-source tools.

 

Who will work on Cello?

Currently, Baohua Yang and Haitao Yue from IBM Research are committed part-time to developing and maintaining the project. There are also sponsors from Soramitsu, Huawei and Intel.

Learn more about Cello

Cello is hosted at github. We will follow the Hyperledger community’s guide, all information is open at the wikipage at https://wiki.hyperledger.org/projects/cello.md. Please connect up directly with the Cello team.  Their contact details can be found at https://wiki.hyperledger.org/projects/celloFor those interested in other technical projects under Hyperledger, please reach out to: info@hyperledger.org.
