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.

New Hyperledger Governance, Risk and Compliance Special Interest Group Set to Launch

By Aravind Voruganti, IDS Inc, and Sunay Zelawat, MetricStream Blog, Special Interest Group

We would like to call your attention to the launch of the Hyperledger Governance,Risk and Compliance Special Interest Group (GRC SIG). The Hyperledger GRC SIG intends to focus on the adoption of blockchain technology in solving digital trust issues, making GRC practices more transparent, and simplifying the adoption by GRC practitioners.

Join us for our first meeting on February 9th, 9:30 PM IST/8 AM PST/4 PM GMT – Meeting Details

Technology has solved many legacy challenges, simplified processes and brought optimization, but, at the same time, it can add more complexities and expose to various risks if organizations don’t have expertise or adopted technologies in their nascent stage. With this SIG, we will help practitioners not just get familiarized with the technology but also assist in solving business trust issues by building decentralized GRC apps. We will also help them educate their organizations or customers about how to define the right set of controls to mitigate IT risk because of blockchain adoption.

To keep it simple, this group will explore using decentralized, permissioned Hyperledger blockchain technology to build applications that will streamline the way global organizations run their GRC practices. Blockchain has a huge potential for building trust and improving data accessibility by maintaining transparency along with cryptographic hash security. The SIG will discuss and explore the following relevant technologies:

Hyperledger Fabric and other Hyperledger umbrella projects for GRC
Tokenomics
DAO and Distributed Governance Models
New Consensus Mechanisms

The Governance, Risk and Compliance process includes these three elements:

Governance is the oversight role and the process by which companies manage and mitigate business risks
Risk management enables an organization to evaluate all relevant business and regulatory risks and controls and monitor mitigation actions in a structured manner
Compliance ensures that an organization has the processes and internal controls to meet the requirements imposed by governmental bodies, regulators, industry mandates, or internal policies.

As part of this SIG, we will explore the areas within GRC space where blockchain can play a crucial role. For example, blockchain can help with digital trust in third party partnerships. It can also promote adoption of technology for IT auditing, organization and regulatory compliance when it comes to blockchain-based enterprise solutions, crypto and NFTs, transparent Environment Social Governance aspects, and more

To make this group successful, we would be happy to work with enthusiastic developers, students, GRC practitioners and all manner of professionals to take this SIG forward and make it into an industry standard.

Visit our GRC SIG wiki page to learn more details about the SIG’s charter and how to get involved. We encourage you to join this community by visiting the links below:

Why is Interoperability Needed?

By Hyperledger Cactus, Hyperledger FireFly, Weaver and YUI technical communities Blog, Hyperledger Cactus, Hyperledger Firefly, Hyperledger Labs

Blockchain interoperability is one of the crucial features of blockchain technology, operating in three main vectors: enabling scalability, diminishing risks and eliminating silos¹. This blog post focuses on interoperability projects connecting data and value silos.

Standardization bodies are pushing forward drafts to normalize operations across the different interoperability layers. Those working on standards includeOpen Digital Asset Protocol (ODAP) from IETF², the interoperability working group in Digital Currency Global Initiative (DCGI) at ITU³, the subgroup 7 (ISO/TC/SG7) from ISO TechnicalCommittee 307⁴, the Cross-Chain Interoperability working group at the Ethereum Enterprise Alliance⁵, and many others⁶. Interoperability solutions can follow guidelines from standardization bodies for seamless integration across their targets and other interoperability solutions.

Several blockchain interoperability projects focusing on solutions for interoperability among public blockchains flourished in the last years⁶. However, enterprise-grade interoperability solutions have only recently emerged, and the necessary standardization effort is still in its infancy. Although many different categorizations exist⁶, we can broadly classify interoperability solutions into two categories with different philosophies and approaches. In the first, a common “settlement” chain (or hub) is created as a permanent infrastructure to which other chains (e.g., “sidechains”) can connect; the common chain serves as an interoperation medium, offering decentralized trust guarantees to the sidechains for the settlement of cross-chain transactions. Cosmos⁷ and Polkadot⁸ exemplify this approach, which is particularly suited to public blockchains and distributed ledgers.

In the second category of interoperability solutions, a blockchain network, be it public or private, is augmented with modules and capabilities that allow it to interoperate directly with another network without depending on third-party infrastructure. This second category, into which Hyperledger Cactus⁹ and the Hyperledger Lab Weaver¹⁰ fall, is useful in enterprise scenarios where privacy as well as performance are core concerns. Both these approaches have their pros and cons, which are scenario dependent.

The Hyperledger community has been involved in notable efforts to advance open source solutions that respond to modern interoperation needs, which can be wide-ranging, and provides a collection of solutions from which blockchain users and consortia can select as per their requirements. This post explores how four technologies (two projects and two labs) under the Hyperledger umbrella approach the interoperability problem (public blockchains – consortium blockchains – centralized systems), comparing them across multiple criteria.

Hyperledger Cactus

Hyperledger Cactus is a pluggable enterprise-grade framework to transact on multiple distributed ledgers without introducing yet another competing blockchain. It’s an SDK of SDKs.

Hyperledger Cactus aims to provide Decentralized, Adaptable and Secure Integration to and between Blockchain Networks. It aims to cover as many protocols as possible through an extensible plugin architecture where new protocols or functionality can be added by creating new plugins.

Hyperledger FireFly

Hyperledger FireFly provides an API orchestration layer over multiple blockchain ledgers, fostering interoperability in the application tier. Allowing common blockchain programming constructs like tokens, off-chain/on-chain data orchestration, and identity verification to be implemented in pluggable microservice code modules against multiple blockchains. Patterns already implemented that span multiple chains in a single business transaction, include using a Hyperledger Fabric DLT for private business agreement and document verification, orchestrated with tokenized value transfer on a separate Ethereum blockchain. FireFly also provides an API layer into which blockchain interoperability platforms can plug into in the future, for a simplified developer experience.

Weaver

Weaver, a Hyperledger Lab, is a framework with a family of protocols to enable interoperation for data sharing and asset movements between independent networks built on heterogeneous DLTs in a manner that preserves the core blockchain tenets of decentralization and security.

Interoperation using Weaver does not rely on trusted mediators. Rules and requirements are framed using the networks’ internal governance mechanisms. Interoperation relies minimally on shared infrastructure, which may provide identity services but does not play a part in core protocols through which data and assets are shared. Interoperation occurs through protocols that derive their trust from the counterparty networks’ native consensus mechanisms.

Currently, a protocol for data sharing across ledgers with proof of authenticity and provenance is supported (for Fabric and Corda). We are currently adding a new protocol that enables asset exchanges using the HTLC pattern.

YUI

YUI is a Hyperledger Lab that achieves interoperability between multiple heterogeneous ledgers. The lab provides modules and middleware for cross-chain communication as well as modules and tools for cross-chain application development.

For cross-chain communication, YUI is based on Inter Blockchain Communication (IBC) protocol by Cosmos project, with extensions to support various Hyperledger projects. IBC provides the basis for ledgers’ interaction of arbitrary data transfer and computation without the assumption of the trusted third party.

Currently YUI supports cross-authentication between enterprise ledgers (Fabric, Besu and Corda). Each actor of ledgers has to interact with only a respective ledger of its interest to complete a cross-chain operation such as an atomic swap of tokens.

Developer showcase series: Sam Curren, Indicio

By Hyperledger Blog, Developer Showcase

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Sam Curren, Architect at Indicio.

Give a bit of background on what you’re working on and how you got into blockchain

Three things keep me busy: I am co-chair of the Hyperledger Aries working group, I lead the DIDcomm v2 working group, and I’m an architect for Indicio. I’ve been involved in various aspects of Identity prior, but I got into blockchain by working at the Sovrin Foundation. I was there when Indy became a Hyperledger project and later for the spin out of the Aries and Ursa projects. The Agent and Cryptographic aspects of Indy were applicable outside of the Indy project, and establishing them as independent projects allowed an expansion of their use.

What Hyperledger frameworks or tools are you using in your projects? Any new developments to share? Can you sum up your experience with Hyperledger?

I use Hyperledger Indy and Hyperledger Aries day to day, looking forward to the finalization of Didcomm v2 and helping the Aries community adopt it. I am also excited about the upcoming work with the did:indy method Indicio will be implementing as part of a BCGov project.

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

Keep up the good work in helping to boost projects through both bringing together developers and marketing. Also continuing to help educate the average person is super important.

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

Make sure you are using the right tool for the job. Carefully select a ledger when you need the features of a ledger, and stick with more traditional approaches when a ledger is not necessary. Understanding the technology and using it in the correct way is more important than trying to force a popular solution onto your project for bragging rights.

As Hyperledger’s projects continue to mature, what do you see as the most interesting technologies, apps, or use cases coming out as a result?

I am most excited by projects that get this technology into the hands and lives of regular people. It doesn’t matter how cool we make something – if it doesn’t positively impact people’s lives, I think we’ve fallen short of our goal.

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

I believe that properly deployed blockchain technology has the power to make people first-class citizens on the internet again.

Where do you hope to see Hyperledger and/or blockchain in five years?

Widely deployed

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

I have two. First, your contributions and insights are valuable; dont assume that people that have been in the industry a while are the ones who have all the answers. Secondly, just try it. Your solution will work more often than not, and you’ll learn plenty of useful stuff in the process.

What technology could you not live without?

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.

“It is a fantastic experience to participate in an open-source project under Hyperledger Foundation. During my mentee career in Hyperledger, the project what I worked on is “Extend secure DID Registry for Hyperledger frameworks on GitHub/Gitlab.” It aims to automate the process of creating a secure DID Registry on GitHub/Gitlab, facilitating easy on-boarding of new organizations and enabling easy management. Under my mentors’ supervision, I completed the entire design and intern workflow and created a new GitHub VCR project based on my current work. We are currently seeking opportunities to establish a Hyperledger research lab to promote the two projects.

Thank my mentors, Mr. Vinod Panicker and Mr. Arun Prakash. Their professional skills and insights have won many admirers and are indeed a great inspiration for me. Through the fantastic journey, I learned technical skills and became part of the Hyperledger community, which are both exceptionally beneficial for me. I appreciate the people I’ve met in the community. Everyone is enthusiastic about wild knowledge and willing to help others.”

“Wei has been outstanding on this project . He was quick to get into the thick of things in the project and was able to develop on the previously seeded DID Registry project ‘DIDman.’ Wei built on the concepts we came up to seed a GitHub-based VCR (Verifiable Credential Registry). Wei’s commitment and enthusiasm to make this project a success is evident in the way he was able to align his future research work also based on this project. I would like to also applaud and specifically mention Arun’s role again here for continuing to back this open source project, which we started with him being the first mentee. Arun is now shaping out as an excellent mentor. Last, but not least, I would also like to thank Hyperledger Foundation and the Mentorship program team for their continued support.”

“Last summer, I was a mentee for the same project. My continued interest in the project and tremendous support from Vinod inspired me to take the role of mentor this summer. Our mentee, Wei, was exceptional in understanding the core objectives and was able to produce outstanding architectural designs for the project. Wei has really made use of this opportunity to a greater extent as he was able to relate his current academic research with this particular project so it was quite easy for him to visualize the end product. He really improved his architectural skills and had productive hands-on experience with deployment, integration, and testing of various Hyperledger frameworks during this mentorship program.”

A special thanks to the Hyperledger member companies for funding this important program. To learn more about our Hyperledger Mentorship Program and how you can participate in our next cohort, head over to our program overview page on the Hyperledger wiki.

“The Giving Chain not only gave me an amazing opportunity to learn about the Hyperledger umbrella by working on an open-source project but also helped me build great communication and presentational skills. I got to know about the Hyperledger FireFly and Sawtooth frameworks. I also made amazing friends and working with Bobbi made me realize how amazing of a community Hyperledger is. I wish to continue working with her and learning as much as I can.”

“The Giving Chain project showcases blockchain technology by creating a platform that makes make donations immutable and transparent. The Giving Chain platform is a supply chain blockchain to seamlessly track donations for charity and disaster relief efforts. The first attempt to create the Giving Chain was in 2019. Through the Linux Foundation 2021 Mentorship Program and the mentee’s talent, The Giving Chain was able to successfully build a proof of concepts using Hyperledger FireFly. Watching young students work so incredibly hard to achieve this milestone for such a worthwhile effort was one of the most rewarding events of my career.”

Staff Corner: 2021 in Review and a Look Forward

By Daniela Barbosa Blog, Hyperledger Foundation Staff Corner

As I look back at 2021, I am amazed by what we as a global community have achieved together in our journey to be the premier open source community of software developers building enterprise blockchain, distributed ledgers, and related technologies.

First, I want to thank everyone for your passion and commitment to the Hyperledger community. Without your contributions and support, we could not have achieved any of the highlights I have included below. There are thousands and thousands of you out there, touching so many aspects of our community and ecosystem, and I hope each of you sees how you have contributed to our successes this year and how you are helping us build upon them for 2022 and beyond.

The list below may seem overwhelming at first, but this is what we are creating worldwide. We have been busy, educating, building, improving, innovating and becoming leaders across multiple ecosystems.

For me, often it seems that not a day goes by without me discovering something new that our community is doing and building with Hyperledger technology. I know that this volume of activity makes it hard for people to understand what “Hyperledger” is, how they can use Hyperledger technology or simply how to get involved in our community so they can also learn, build and innovate.

This year, as we prepared to celebrate our 6th year anniversary, we acknowledged that the Hyperledger of today is not the same as the Hyperledger of 2016. In October we announced that Hyperledger is now Hyperledger Foundation. As our ecosystem and community grow, we need a clear identity for our organization that arches over all our projects, labs, regional chapters, working groups, special interest groups and overall collective effort to advance enterprise blockchain technology. The Hyperledger Foundation brand offers that clarity. It also positions us to fulfill our newly updated mission to be the premier community of software developers building enterprise grade open source software, in the form of platforms, libraries, tools and solutions, for multiparty systems using blockchain, distributed ledger, and related technologies.

This year, we have seen growth across all areas of the Hyperledger Foundation – from new projects to virtual events and growth in our ecosystem and community as outlined below and in the recent Hyperledger Foundation 2021 End-of-year Update on the Linux Foundation Blog. I believe that 2022 will be a year of acceleration for enterprise blockchain as I highlighted in this op-ed Up the adoption curve: why 2022 will be a year of acceleration for enterprise blockchain on the enterprise blockchain news website Ledger Insights.

This fall we also published an updated Hyperledger Foundation overview paper that provides a high-level overview of Hyperledger as an organization, including why it exists, what it does, and who is involved. It also covers our Hyperledger technologies and their impact on existing and new markets. Finally, this paper looks at the roadmap to widespread adoption of Hyperledger platforms, tools, and libraries to power a new generation of multiparty systems. If you have not had a chance to read it, I encourage you to.

Our 2021 Hyperledger Brand Study provided some insight on how Hyperledger is perceived in the market and confirms much of the progress both the industry and Hyperledger have made in just over five years.

In October, I took over as Executive Director of the Hyperledger Foundation after four years as Vice President of Worldwide Alliances serving our community worldwide. Over the last few months, I have spoken with many of you about what you see our community becoming and how you want to contribute, and I am really forward to working with you and our staff to make the Hyperledger Foundation a place for anyone who wants to advance, adopt and build the future of blockchain in the enterprise.

They say it takes a village, but leadership is also important so we are also grateful for the stewardship that Brian Behlendorf provided our Hyperledger community since 2016 and look forward to his successes as Executive Director of the new Linux Foundation project, Open Source Security Foundation.

As we head into 2022, I want to pause to also acknowledge the challenges and losses that many in our community have experienced as we collectively move through this global COVID pandemic.

On behalf of the entire Hyperledger Foundation team, I want to also congratulate all our communities for their successes under another extraordinarily challenging year and wish you all a happy, healthy and prosperous 2022.

I hope you enjoy reading these fantastic highlights and reflecting on the incredible progress we have achieved together this year.

Project Updates

The Hyperledger project landscape is a diverse grouping of distributed ledgers, tools and libraries. Six graduated Hyperledger Projects and 11 incubating Hyperledger Projects represent our project community as defined by our project lifecycle.

Hyperledger Project Landscape

The project lifecycle is governed by our Technical Steering Committee, which consists of 15 elected members of the technical contributor community. The responsibilities of the TSC are to steer the technical direction for Hyperledger. Each year, the Hyperledger technical community holds an election to select a new Technical Steering Committee (TSC) from the community at large. The main objective of the TSC is to drive technical governance for the projects and technologies hosted by the Hyperledger Foundation. The 2021-2022 TSC was elected in October and you can read more here. This year, the TSC is being led by Tracy Kuhrt, Associate Director, Blockchain and Multiparty Systems Architecture, Accenture (chair), and Danno Ferrin, Principal Software Engineer, Hedera (vice chair).

Each quarter all Hyperledger projects report to the TSC, and it is a great way for our community to understand how these projects are doing, what future work is being planned and how contributors can participate. Read our 2021 Updates here.

Some 2021 project highlights include:

In February 2021, Hyperledger Aries graduated to active status and joined Hyperledger Indy as “production ready” Hyperledger projects for decentralized identity. Hyperledger Aries provides reusable, interoperable tool kits designed for initiatives and solutions focused on creating, transmitting and storing verifiable digital credentials. Read more here.

This year, the Hyperledger Besu project community decided to switch its versioning to calendar versioning, known as CalVer, instead of the historic semantic versioning used by other Hyperledger projects. Some of the newest release features include the Flexible Privacy Group Performance tests and Mainnet Support Work, including preparing for the Berlin Network Upgrade and EIP-1559 support. Read more here.

Hyperledger Fabric v2.4.1 was released Dec 17th 2021. v2.2 is the current LTS release with patch releases quarterly. Hyperledger Fabric has stabilized with an LTS release process and incremental new features being added in minor releases. View all quarterly reports.

2021 brought us two new projects, Hyperledger Bevel and Hyperledger Firefly!

New Project: Hyperledger Bevel

Announcement Date: December 13, 2021

Hyperledger Bevel is an accelerator/tool that helps developers rapidly set up and deploy secure, scalable and production-ready DLT network(s) that also allows new organizations to be easily on-boarded on the network. Bevel, started as a Hyperledger Lab called Blockchain Automation Framework (BAF) and built a community of contributors during 2021. Learn more.

New Project: Hyperledger Firefly

Announcement Date: September 28, 2021

Hyperledger FireFly is a multi-party system for enterprise data flows. It provides a purpose-built system upon which to build decentralized blockchain applications. It solves for the layers of complexity that sit between the low level blockchain and high level business processes and user interfaces. FireFly enables developers to build blockchain apps for enterprises significantly faster by allowing them to focus on business logic instead of commodity infrastructure foundations. Learn more.

Innovations in our Hyperledger Labs

Hyperledger Foundation aims to help build communities by gathering people sharing a common interest in developing blockchain related software. Hyperledger Labs provides a space where work can easily be started without the creation of an official Hyperledger project. Hyperledger Labs have been not only a very active part of our community in 2021, but have nurtured new projects Hyperledger Bevel and Firefly as outlined above.

Today there are over 50 Hyperledger Labs that our community is working on including Minifabric: a Hyperledger Lab aimed at accelerating the move to production and YUI, one of the new Hyperledger Labs taking on cross-chain and off-chain operations.

The top 10 Most Active Labs by Pull Requests are as follows: (as of Nov 2021)

Blockchain-automation-framework (now Hyperledger Bevel)
business-partner-agent
orion (orion-server, orion-sdk-go)

blockchain-carbon-accounting
fabric-operations-console

Hyperledger Events

Hyperledger Global Forum

While we all wanted to gather in person, like we did in March 2020 in Phoenix, Arizona (one of the last in-person events many of us attended), 2021 forced us to have Hyperledger Global Forum as a virtual event from June 8-10. The event was a success and feedback from the attendee survey was overwhelmingly positive: 97% would recommend this event to an industry friend.

We had a lot to celebrate as a community as we got together in June and as David Treat, Global Technology Incubation Lead and Global Blockchain Multiparty Systems Lead, at Accenture, said in this post leading up to the event, “In the year since we last saw each other, we’ve made immense progress in inventing new forms of money, re-platforming financial services infrastructure, rearchitecting supply chains into resilient and secure supply networks, and pursuing self-managed digital identity.”

The three day event was jam packed with presentations and panels from companies, developers and communities building with Hyperledger and had over 250 virtual speakers. Keynotes included HE Serey Chea, National Bank of Cambodia, Frank Yiannas, Deputy Commissioner FDA, a fireside chat with Vitalik Buterin, Co-Founder, Ethereum and more. Some highlights of sessions on CBDCs, programmable money and interoperability can be found in this two part post – Part I and Part II. And other recorded sessions, on topics like Climate Action, Supply Chains, NFTS and more.

A big thank you to our event sponsors and partners for HFG 2021 including: Accenture (Diamond and Diversity & Inclusion Sponsor), IBM (Diamond Sponsor), Filecoin Foundation (Platinum), Hitachi (Platinum), Siemens (Platinum), Zuellig Pharma (Platinum), AWS (Silver), BTP (Silver), Chainyard (Silver), ConsenSys (Silver), KrypC (Silver & Wellness), DTTC (Closed Captioning and Translation), Walmart Global Tech (Parent & Caregiver Support Program), Crypto Open Patent Alliance – COPA (Birds of Feather), Black Women Blockchain Council (Community), Diversity in Blockchain (Community), Enterprise Ethereum Alliance (Community), Greater Blockchain Business Council (Community), Kerala Blockchain Academy – KBA (Community), Trusted Blockchain Initiatives (Community), Blocknews (Media Partner), Cointelegraph China (Media Partner), CoinSpeaker (Media Partner), CrytoNewsZ (Media Partner), Forekast (Media Partner), Ledger Insights (Media Partner) and Tuoluo Finance (Media Partner).

Hyperledger Member Summit

Hyperledger Member Summit 2021 The Hyperledger Member Summit took place online this year for the second consecutive year. Since virtual has lost its novelty, we streamlined the event to two half-day sessions to reach two regions. With 349 people registered, about 220 attendees across two regional programs, 11 sessions total, and 130+ companies represented, we had a strong showing for our second Hyperledger Member Summit in the Covid era. The overall feedback has been overwhelmingly positive from our members who attended.

Our Member Portal, once again served as a collaboration tool to document the activities and proposals coming out of the Summit. As a result, anyone that works at a member company can go back and review the recordings and SWOT output from each session throughout the year. Given the success of it last year, we brought back the China Community session to allow broader participation and inclusivity in our member community. In addition, interpreters allowed for our Chinese community to listen to the entirety of the event in Chinese.

We thank all our Hyperledger Member community members for their participation and contributions to this year’s Member Summit!

Hyperledger Member Webinars

Showing what is possible with Hyperledger technology is an important part of how the Hyperledger Foundation serves members and the community. One of the best ways to do that is to highlight what our member companies are building with different Hyperledger projects. Our Member Webinars is a series of hour-long sessions where Hyperledger members share learnings from their projects and try to answer all the hard questions about the opportunities and challenges of working with DLTs.

In 2021, our members contributed to 24 virtual webinars covering multiple projects, like Hyperledger Fabric, Hyperledger Besu and Hyperledger Indy, across various use cases, including NFTs, DeFI, CyberSecurity and more.

CHECK OUT OUR WEBINAR LIBRARY (filter by Topic> Member Webinar) TO SEE WHAT MEMBERS ARE BUILDING

Community & Diversity

Our community is global and growing. Developing community at the local level, joining together to take on technical and industry challenges and creating pathways for developers to learn skills and build careers are all central to our work of fostering a thriving ecosystem around open source blockchain software technologies.

Our Hyperledger Meetup Community by the numbers in 2021:

Number of virtual meetups: 135 (A small number of in person events were also held in 2021, including the very first Hyperledger meetup in Rwanda! See video)
Number of participants at meetups: Over 5,000 attendees at virtual events
Number of languages used to host meetups: 12 (Spanish, Italian, Polish, Serbian, Portuguese, French, Urdu, Korean, English, Japanese, Hungarian, Chinese)
Number of people in Hyperledger meetup groups: over 81,000!

Many of our Meetups are live streamed/recorded and available on YouTube via our Meetup playlist. Some recent highlights from 2021 include:

Interoperability among Blockchains – Hyperledger Frankfurt – Dec 17th 2021
Hyperledger Tokyo Virtual Meetup – Hyperledger Tokyo – Nov 25th 2021

Looking for other places to connect into the Hyperledger community? One of the highlights of 2021 has been the activity and contributions of our virtual global communities. Find a local or industry connection with our:

Regional Chapters: Hyperledger Regional Chapters are organized groups of community members in different parts of the world that are working together to address contribution barriers in their regions. We currently have chapters in Africa, Brazil, India, Italy, Japan and Latinoamerica. Check out our YouTube Regional chapter playlist for the latest event
Special Interest Groups – Hyperledger SIGs are communities focused on a particular industry sector or activity with a shared interest in advancing a common understanding of how blockchain technology in general, and Hyperledger technology in particular, may be applicable. Many of our SIGs are live streamed/recorded and then available on the SIG youtube playlist or on their wiki agenda pages

Special acknowledgment to our Chinese community, especially to our Technical Working Group China/超级账本中国技术工作组 (TWG China or TWGC), that is a bridge between the global Hyperledger community, and the emerging technical user and contributor community in China and the greater China region, including Hong Kong and Taiwan.

Training & Certification

As we recently wrote in our Staff Corner blog series, one of the biggest barriers to growth for the blockchain industry is the talent gap for developers with the right skills and training. Recognizing the coming demand, Hyperledger Foundation, in partnership with the Linux Foundation Training, has worked for years on developing a robust and growing set of enterprise blockchain training and certifications for developers.

We continued to enhance and offer more options for our community including:

In 2021, we updated our Blockchain Essentials courses that over 200,000 people have taken since its launch:

Blockchain: Understanding Its Uses and Implications – Enroll for Free

Understand exactly what a blockchain is, its impact and potential for change around the world, and analyze use cases in technology, business, and enterprise products and institutions

Blockchain for Business – An Introduction to Hyperledger Technologies – Enroll for Free

A primer to blockchain and distributed ledger technologies. Learn how to start building blockchain applications with Hyperledger frameworks.

New for 2021:

We also launched a new self-paced online course for Hyperledger Besu developers:

Hyperledger Besu Essentials: Creating a Private Blockchain Network – Enroll for Free

This course will provide a learner with insight into how to create a private blockchain network or to connect to Ethereum mainnet and use Hyperledger Besu to do these activities, and provide examples of where Hyperledger Besu is being used.

We announced Hyperledger Indy and Aires Workshops for Q1 2022 that complement our free online existing course: Introduction to Hyperledger Sovereign Identity Blockchain Solutions: Indy, Aries & Ursa and Becoming and Aries Developer.

Our Hyperledger Fabric Developer and Administrator Certifications were also updated in 2021 and are becoming core requirements for Hyperledger Fabric engineers.

And, last but not least, we know that blockchain technology needs to be taught and understood at the executive level across all industries so in 2021 we partnered with Wharton Wharton Executive Education on their 2022 “The Economics of Blockchain and Digital Assets” online certification. Our Hyperledger community contributed to the course work and hosted a webinar to share more information about this program. The curriculum includes case studies on deployments by two Hyperledger Foundation members:

Soramitsu’s Bank of Bakong CBDC project, built using Hyperledger Iroha
Poste Italiane’s new generation of digital identity services, which is powered by Hyperledger Besu

Mentoring

2021 Mentorship Program. This year we sponsored 21 mentorships- The Hyperledger Mentorship Program is a structured hands-on learning opportunity for new developers who may otherwise lack the opportunity to gain exposure to Hyperledger open source development and entry to the technical community.

Check out these Mentorship Spotlights that highlight the work done by the Mentors and the Mentees as part of their program participation.

Hyperledger Ecosystem Expansion at the Linux Foundation

2021 was also the year that Hyperledger technologies made their way again across to other Linux Foundation open source projects some examples:

openIDL – The Open Insurance Data Link platform and project built with Hyperledger Fabric formally launched on April 12th with major insurance carriers like Hanover, The Hartford and Travelers in partnership with AAIS. The platform aims to reduce the cost of regulatory reporting for insurance carriers, provide a standardized data repository for analytics and a connection point for third parties to deliver new applications to members. As of December, US insurance state regulators from Mississippi, Virginia, Main and Connecticut are members of openIDL and actively participating in the open source project.
LF Public Health – Launched the Cardea project built on the Hyperledger technology. Cardea is a complete ecosystem for the exchange of privacy-preserving digital health credentials, open sourced by Indicio.tech as a project in LFPH.

Wow, you made it to the end of 2021 year in review post. Congrats! But this is only the start of great things our community will be building and delivering in 2022 and beyond.
