Four Takeaways From Hyperledger Global Forum 2020

Phoenix, AZ

What a great place for an early spring conference! The weather was perfect, the city was beautiful and the people were amazing. We were also able to take in a Suns game against the defending NBA champs, the Toronto Raptors.

Concerns over the rapidly progressing coronavirus (COVID-19) may have slightly dampened the attendance numbers, but it didn’t dampen the enthusiasm. Attendees replaced handshakes for elbow bumps and lots of hand sanitizer while taking in the latest innovations at the conference.

In no particular order, here are our Top Three Takeaways from the recent Hyperledger Global Forum:

Fabric has become the dominant permissioned blockchain for enterprise

No two companies have made greater inroads towards the development and build-out of enterprise blockchain networks than IBM and Accenture. And both were ever-present on the technical and business tracks discussing the latest findings from their global implementations.

The consistent theme we heard from attendees is that Fabric continues to deliver on its core promise of modularity and flexibility. So it’s only natural that it continues to be the go-to choice for new enterprise projects. With the recent release of Fabric 2.0, it is clear Hyperledger is focused on maintaining its competitive advantage.

As one person said (who didn’t want to quoted directly)… “it’s a virtuous cycle, the more projects that leverage Fabric, the more the community gets exposure to real world use cases and has the ability to develop and harden those solutions.”

Interoperability is still key to success and the community is strong

And yet, there were plenty of presenters talking about the need for interoperability between frameworks, identity solutions, and legacy business systems.

For the development community, this means opportunity to provide tools and resources for connecting networks built on other frameworks. Also, opportunities to stay flexible within the design and implementation of specific Fabric networks to ensure future optionality.

For the business community, interoperability means continued freedom. Freedom to move forward without fear of being “locked-in.” Or investing development resources and time on a closed framework. It also means flexibility to accommodate future network partners which will become critical as networks mature and business ecosystems gravitate towards blockchain-enabled solutions.

Hyperledger Besu (or “Ethereum on Fabric”) Has Arrived

The PegaSys team was there to provide an overview of Hyperledger Besu and help usher in a new era of Ethereum on Fabric. The team started focusing on Besu’s development a few years ago when they saw very little focus on Ethereum from within the Hyperledger community. From their perspective, Fabric had a strong foothold in the enterprise community. Ethereum, on the other hand, offered amazing access to perhaps the world’s largest development community.

What seemed like a natural alliance proved difficult at times. In fact, there was discord among the Hyperledger Technical Steering Committee about the Besu project. Even our own CEO had to step in to help preach inclusion in order to provide a path towards developing the best possible Ethereum-based framework.

And they have come a long way! PegaSys’s Maryam Mahjoub made the case for Ethereum for Enterprise: the ability to leverage Ethereum’s ecosystem and mainnet, quickly deploy your own network, and benefit from native tokenization.

The Kaleido team was also at HGF to demonstrate their solution which helps projects stand up networks in minutes.

We’re looking forward to seeing what sort of traction the Besu team is able to get in the coming 12 months!

Token capabilities with DAML on Fabric might be the silver-bullet for Financial Applications

Ok, we threw this one in here… because this was our main focus heading into the conference. But we think it’s fair to say our live demo impressed a lot of folks! We demonstrated the ability to issue/create, allocate and exchange tokens on an “out of the box” implementation of Fabric. The tokens were managed by a DAML-based smart contract, making the whole implementation portable by construction.

Most importantly, we did not modify a single line of code in Fabric to make it happen! The live demonstration proves companies – right now – can adopt the utility and flexibility of tokens. It also demonstrates that companies can manage their tokens through smart contracts implemented through DAML-on-Fabric smart contracts. DAML-on-Fabric is a solution we’ve been developing in partnership with Digital Asset for most of 2019.

Assets represented by tokens. logic was managed by DAML app, on a highly secure and scalable enterprise framework. Throw in some transaction level privacy and other key features from HACERA and you have the ultimate, enterprise-grade application, which can be seamlessly deployed even in highly-regulated environments.

My Thoughts On The Recent Fabric 2.0 Release

In late January of 2020, Hyperledger released Fabric 2.0 to the community at large. It was an incredible moment for me, personally, as I’ve spent much of the last few years deeply invested in the framework.

Recently, the editors at Unbounded Network – a sister site dedicated to connecting all blockchain projects across all frameworks – asked me to sit down for a short interview following the announcement. Click here to read the transcript. I touch on everything from lingering myths about the framework to the features I’m most interested in seeing in production.

If you have any questions or comments, I would love to hear from you!

The Linux Foundation partnered with HACERA to create the world’s first vendor agnostic Hyperledger Fabric Fundamentals class


SAN FRANCISCO, September 5, 2018The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced enrollment is now open for the new LFD271 – Hyperledger Fabric Fundamentals training course. Additionally, Certified Hyperledger Fabric Administrator and Certified Hyperledger Sawtooth Administrator exams will be released later in the year. A Professional Certificate Program – Blockchain for Business – was launched earlier this year on edX along with a free course entitled Blockchain: Understanding Its Uses and Implications.

LFD271 – Hyperledger Fabric Fundamentals

The Hyperledger Fabric Fundamentals course introduces the fundamental concepts of blockchain and distributed ledger technologies, as well as the core architecture and components that make up typical decentralized Hyperledger Fabric applications. Students will work with Hyperledger Fabric, Hyperledger Fabric Certificate Authority and the Hyperledger Fabric SDK. In addition to the reading material, the two day, self-paced course includes a set of hands-on lab exercises that guide students towards setting up a Hyperledger Fabric business network and through the various stages in the lifecycle of a decentralized Hyperledger Fabric-based application.

LFD271 is designed for developers and application developers. Developers will learn how business logic is implemented in Hyperledger Fabric through chaincode (Hyperledger Fabric’s smart contracts) and review the various transaction types used to read from and write to the distributed ledger. Application developers will be shown how their applications can invoke transactions using the Hyperledger Fabric JavaScript SDK.

The course instructor, Jonathan Levi, is a hands-on computer scientist, applied cryptographer and mathematician, as well as the founder of HACERA, the blockchain technology company. He is one of the early contributors to Hyperledger Fabric, helped shape the Membership Services (the permissioning layer of Hyperledger Fabric) and was the official release manager of Hyperledger Fabric 1.0. He has built several large-scale mission critical systems that had to be highly available, secure and fault-tolerant. Over the last five years, Jonathan has worked with several blockchain technology stacks – from Bitcoin to building the first Ethereum class with Professor Dan Boneh at Stanford University.

Hyperledger Fabric 1.0 is Released!

Chris Ferris, Chair of Hyperledger Technical Steering Committee, CTO Open Technology, IBM and Jonathan Levi, nominated release manager of Hyperledger Fabric 1.0, creator of HACERA

Today, we are pleased to announce Hyperledger Fabric 1.0.0 is now available! But what does the 1.0 designation really mean?

This is a huge milestone for the community. 159 engineers from 27 organizations contributed to Hyperledger Fabric and 57 engineers, writers and testers contributed to the post-beta cleanup effort. It is amazing to see what this highly collaborative community with more than 145 members has achieved in a little over a year. Just 16 months ago, Hyperledger Fabric became the first of the now eight Hyperledger projects to be incubated. Hyperledger Fabric was also the first of the Hyperledger projects to exit incubation to “Active” status in March, after a year in incubation.

The efforts around Hyperledger Fabric have grown into a true, vibrant community including engineers from: Arxan, Cloudsoft, CLS, d20 Technical Services, The Depository Trust & Clearing Corporation (DTCC), Digital Asset, Fujitsu, GE, Gemalto, HACERA, Hitachi, Huawei Technologies, Hyperchain, ImpactChoice, IT People, Knoldus, The Linux Foundation, Netease, Passkit, State Street Bank, SecureKey, IBM, SAP, Thoughtworks and Wanda Group. There were also contributions from 35 unaffiliated individuals. In total, 159 developers have contributed to Hyperledger Fabric.

Along the way, we published two developer preview releases, and we learned a lot from the feedback from the many users developing proofs of concept/technology built using those releases. With that important feedback, we undertook a significant refactoring of the architecture and re-wrote much of the code, as you can see with the visualization of the commit history.

No open source project is ever “done,” and the same can be said for Hyperledger Fabric. There’s much that we want to do, including improve delivery of a Byzantine Fault Tolerant orderer capability, explore integration with other Hyperledger projects such as Sawtooth, Iroha, Indy and Burrow, add support for Java and other chaincode development languages, deliver additional SDKs for Go and Python, provide a recipe(s) for deployment to Kubernetes, deliver proper installers for the various development platforms, and much, much more.

We also have more work to do on performance and of course we have plans to add more comprehensive performance, scale and chaotic testing to our continuous integration pipeline to continue to add to the robustness of the platform.

However, the project’s maintainers felt that the time was ripe to deliver a robust initial major release with the objective of allowing consumers and vendors of technology based on Hyperledger Fabric to advance to the next stage: production deployment and operations.

Over the past two months, we locked down feature development and focused on static and dynamic security scanning and linting, testing, reducing technical debt and fixing defects. We increased the unit test coverage by 70% and continue to automate our manual SVT integration tests. We have honed our release process by releasing four interim releases (alpha, alpha2, beta, and rc1) and with each, we have been taking user feedback and worked to improve our documentation and initial UX.

So, is it soup yet? We think so, and we’d love for you to give Hyperledger Fabric 1.0 a try. Are we done? Not at all. There’s still much to be done on the journey to delivering on the promise of blockchain in the enterprise. However, to drive the continuous improvement, we need your feedback. Why not join us on this exciting journey to transform how the industry thinks about business network transactions!
