Call to strengthen Open Collaboration among all Hyperledger Working Groups, Special Interest Groups and Chapters

By Mark Cudden, Andrea Frosinini and Eugenio Reggianini Blog, Regional Chapter, Special Interest Group, Working Group

Leaders from Trade Finance, Capital Markets, Climate Action and Accounting, Media and Entertainment, Public Sector, Social Impact, Supply Chain and Telecom Special Interest Groups; Identity, Learning Materials and Development, Performance & Scale and Learning Materials Development Working Groups; and the Italian, Latin America and India Chapters agree:

“We are unearthing ways in which we can better collaborate
to overcome today’s and future cross industry challenges
by identifying and contributing heterogeneous expertise,
leveraging technology for the betterment of society,
unifying open communities under Hyperledger.”

Signatories:

Why?

The Hyperledger Special Interest Groups (SIGs) were initially focused on specific business areas such as Trade Finance (TF), Supply Chain (SC), Healthcare (H), Telecom (T), and Capital Markets (CM). These groups evolved separately and went through their own independent cycles of growth. These SIGs regularly hosted presentations about ways their industries and business domains leveraged open source protocols and software to deliver solutions that overcame their respective challenges.

Gradually, some individual SIGs came together organically and dynamically. In 2020, the Capital Markets SIG and Trade Finance SIG produced an exhaustive and comprehensive picture of the Chinese blockchain infrastructure for Trade and Trade Finance.

In March 2021, Trade Finance SIG and Capital Markets SIG met formally for the very first time to plan collaboration in earnest. That meeting sparked an inner debate within the Trade Finance SIG about how different SIGs in the Hyperledger ecosystem could further collaborate. Perhaps it is natural that large-scale collaboration started with trade finance as, thanks to its hybrid nature, it is intimately connected with many other branches of human activity.

Observations emerged from these initial meetings within the Trade Finance SIG and from initial collaboration with other Hyperledger SIGs that could serve as a role model for future and further open engagement throughout the Hyperledger SIGs.

It became clear that we cannot promote decentralization while locking ourselves in silos. We cannot promote decentralization while imposing singular perspectives on the world. We need collaboration, open communication, and strong connections among Hyperledger communities as we look for solutions to enable interoperability and standards at business and technical levels.

The Hyperledger communities should focus on finding new opportunities that support global adoption of blockchain. Intra WGs, SIGs and Chapters collaboration is a natural step forward identifying opportunities to accelerate that adoption. The goal is to discuss, create or adopt technical, business, legal and regulatory standards that may redefine common global practices for a harmonized worldwide adoption and come up with a set of shared, mutually accepted regulatory framework for the industries to innovate.

Blockchain-based ecosystems are virtual places where members come together to be part of an evolution or indeed a revolution in business practices. Hyperledger has always strived to be a neutral reference point that leverages the expertise of their participants.

We face global events that stimulate or accelerate technological advancements and the need for solutions to resolve some of the world’s most urgent problems—from climate change and sustainability, green initiatives including green trade and logistics, healthcare, provenance, security and privacy. We are uniquely positioned to break the silos and combine our thoughts, ideas and effort in a concerted way to solve these problems.

The creation of a Hyperledger Collaboration Working Group will break the silos through intentional collaboration starting a convergence of the Hyperledger ecosystem addressing large-scale real world problems. This new Working Group echoes the goal of the Linux Foundation itself: “Unlocking the value of shared technology.” Representatives from these groups will meet on a quarterly basis to achieve the goal of open collaboration.

Our Call to Action is for you to participate, get involved, contribute where you can and help us achieve our goal. We encourage the community to roll up its collective sleeves and take on this challenge. A good place to start is the event named “Breaking the silos” that will take place on June 15th.

Come and join us!

Meet YUI, one of the new Hyperledger Labs taking on cross-chain and off-chain operations

By Jun Kimura, CTO of Datachain Blog, Hyperledger Labs

As enterprises and organizations increase their adoption and deployment of blockchain technology and networks, the overall complexity of systems are growing exponentially. While it’s exciting to see the expanding reach of blockchain, it also creates a host of new requirements for cross chain and off chain sharing of data, transactions and more.

At Hyperledger Global Forum (HGF) 2020 in Phoenix, one group of developers got together to share their work and create a blockchain integration tool designed to allow users to securely integrate different blockchains. They brought their project to Hyperledger Labs and, within a few months, it was approved as Hyperledger Cactus.

During this year’s HGF, three new Hyperledger Labs that are each tackling elements of cross-chain or off-chain operations are making their debuts: FireFly, Weaver and YUI. Read on to learn more about YUI.

Meet YUI

By Jun Kimura (https://github.com/bluele), CTO of Datachain (https://twitter.com/datachain_en)

YUI is a new Hyperledger Labs project to achieve interoperability between multiple heterogeneous ledgers. The word “YUI” is derived from a Japanese word to represent knot, join and connect.

YUI provides modules and middleware for cross-chain communication as well as modules and tools for cross-chain application development, including an explorer to track status and events for cross-chain environments.

This is the brief summary of YUI’s design principles.

Cross-Authentication: Cross-authentication allows blockchains to be interoperable without requiring a trusted third party by on-chain verification.

Blockchain-agnostic communication specs: By using a unified communication protocol, we can introduce a blockchain-agnostic message layer between blockchains.

Arbitrary data transfer and computation: By exchanging messages with a unified communication protocol, arbitrary data transfer and computation is possible. It also enables developers to implement arbitrary application logic that is not limited to a token transfer.

Avoid adding components that introduce additional trust: Introducing such components that need additional trust may decrease the level of security of a system as it would be bounded by the lowest security component in the system.

Do not introduce a new layer: Each actor (of ledgers) has only to interact with a respective ledger of its interest to complete a cross-chain operation unless the application has additional requirements.

Check out the YUI’s Lab page to learn more about the design principles of YUI: https://labs.hyperledger.org/labs/yui.html

High Level Architecture

For now, the modules and middleware for cross-chain communication (IBC Module) are available. The basic components of IBC Module are described in the following diagram:

As you can see on the diagram, we have an IBC Module on each ledger and a Relayer between them. As Client modules should be designed to support each underlying ledger, we have built different Client modules for each ledger such as Client modules for Hyperledger Fabric and for Hyperledger Besu.

For cross-chain communication, the design of YUI is based on Inter Blockchain Communication (IBC) protocol by Cosmos project, with extensions to support various Hyperledger projects.

Meet Weaver, one of the new Hyperledger Labs taking on cross-chain and off-chain operations

By Venkatraman Ramakrishna, IBM Research - India Blog, Hyperledger Labs

Meet Weaver: DLT Interoperability

By Venkatraman Ramakrishna, IBM Research – India

We are excited to announce Weaver, a project that was incubated in IBM Research. Weaver is an architectural framework with a family of protocols that enables scalable interconnectivity and interoperability between distributed ledgers while preserving core tenets of decentralization and security. This framework was motivated by the fragmentation of the blockchain ecosystem, with different flavors of permissioned blockchain and distributed ledger technologies (DLTs) leading to the proliferation of independent networks managing processes of limited scope and keeping assets in silos. Weaver’s mission is to link processes and enable seamless but controlled flow of assets and data across network boundaries. It seeks to achieve this while maintaining the autonomy of the networks and the ledgers within and avoiding dependencies on trusted intermediaries.

Overview

Weaver is a general-purpose interoperability framework that provides a common set of capabilities for trustworthy information communication across ledgers, whether they belong to the same network or different networks running on different DLT stacks. Key principles that guide Weaver’s design are:

Accommodate DLT heterogeneity without favoring a particular DLT design
Allow networks to maintain their independence and collective sovereignty
Minimize coupling during cross-network interactions
Rely on common standards for cross-network protocol units
Do not require a trusted intermediary or third-party ledger
Do not require changes to existing DLT stacks
Make no security and trust assumptions on Weaver components
Treat privacy and least privilege as a first-class requirement

Weaver addresses three broad classes of use cases:

Data transfer: ledger data (state) communication with proof
Asset transfer: movement of an asset from one ledger to another
Asset exchange: atomic exchange of asset ownership in different ledgers

The protocols to realize these use cases can be abstracted into a common stack of layers akin to the OSI model, from message formats at the bottom to governance rules at the top (see diagram below).

The Weaver architecture has three major components underpinning it:

DLT-agnostic Relays with DLT-specific drivers to route cross-network requests and responses.
Interoperation modules that operate through their network’s native consensus processes, typically smart contracts or decentralized applications.
Decentralized identity framework to share and authenticate network members’ identities.

The figure below illustrates this architecture, with a typical Fabric network to the left and a typical Corda network at the right. Weaver components are marked in green, and the design of the relay is called out in detail.

Hyperledger Labs Project

The Weaver Hyperledger Labs project was launched at the end of March 2021 with specifications detailed in a set of RFCs, a framework to run end-to-end network tests for updated or new interoperation protocols, and documentation to help users understand Weaver concepts and code in more detail.

Weaver currently offers protocols for data transfers among Hyperledger Fabric and Corda networks, and asset exchanges among Hyperledger Fabric networks. We hope to expand the coverage to more DLTs with the help of the community! Please check out the project repository for useful links and references and start contributing.

Meet FireFly, one of the new Hyperledger Labs taking on cross-chain and off-chain operations

By Steve Cerveny, co-founder and CEO of Kaleido Blog, Hyperledger Labs

Meet FireFly

By Steve Cerveny is co-founder and CEO of Kaleido

Today, we are excited to introduce you to FireFly. FireFly is a multi-party system for enterprise data flows. It provides a purpose-built system upon which to build decentralized blockchain applications. Decentralized applications are a new category of business application. They bring with them a new set of challenges to successfully build and deploy.

In particular, multi-party data flows are complex and require significant plumbing – both cross-party and internally across the stack – to run securely and reliably at an enterprise grade.

Key Ingredients of a Multi-Party System

In our experience, consortia end up trying to build a multi-party system as a side effect of implementing their enterprise blockchain use case. This results in a large amount of “reinventing the wheel” and we’ve observed that most of the resources are spent on plumbing components.

At a high level, enterprise blockchain use cases attempt to coordinate data flows and transactions across disparate, separately owned systems (ERP, mainframe, commerce, etc.). To do this end-to-end, four things are required:

the single source of truth coordination system across parties
per-member plumbing software to enable reliable, private integration to and from the coordination system
cross-org plumbing software that provides robust cross-connectivity among members alongside (1) for use when the coordination system is not suitable or not preferred as the data flow mechanism. Examples include sensitive data, low latency messaging, and large data flows
a control plane to manage all of these runtime and configuration details

We formally define a multi-party system as the set of technology, infrastructure, and management capability to enable a consortium to build and deploy a use case that includes (1), (2), (3), and (4). We observe nearly all the real world consortia that we worked with over the last six years require all of (1), (2), (3), and (4) to build and deploy an enterprise blockchain use case. It is our observation that consortia spend most of their budget on (2) and (3).

Meet FireFly

Hyperledger FireFly brings together (1), (2), (3), and (4) to offer a pre-integrated set of runtimes via a highly pluggable framework. Note that FireFly is NOT attempting to replace or invalidate any specific runtime technology, but rather pulls together multiple complementary technologies into a coherent, larger system. Indeed, many of the infrastructure runtimes FireFly relies on are separate open source projects. Industry consortia globally have been using this technology to accelerate time to value for their production solutions.

Enterprise blockchains are purpose built to deliver (1) with invaluable attributes like global ordering and finality. FireFly will support Hyperledger Fabric, Enterprise Ethereum (such as Quorum and Besu), and will investigate Corda support. (1) also includes global storage providers such as IPFS. FireFly also provides a significant amount of technology for (2) and (3) including cross-party messaging, cross-party private document transfer, and event propagation. All of these runtimes and connectors into the FireFly node. For (4), Hyperledger FireFly also provides a network map and registry that unifies all of the identity and bindings information needed.

In a FireFly network, each member of the network deploys and runs one or more FireFly Nodes. Each Node consists of a FireFly Core application, as well as its dependencies. Each dependency is abstracted from the Core by a modular plugin system, so underlying technologies, such as the database for example, can be changed if necessary.

Why Walmart Supports Hyperledger’s Parents and Caregiver Inclusion Support: Program for Kids

By Archana Sristy, Walmart Blog, Hyperledger Global Forum

The ongoing COVID pandemic has disrupted the global workforce in many ways. While many people are getting back to work, others who are ready to work are unable to do so because they need to care for family members impacted by COVID. They’ve had to make the difficult decision to step back from their jobs or careers in order to step up and be a caregiver — oftentimes because there was no other option. For many in this situation, transitioning back to a career in tech can be difficult after an extended break.

That is why Walmart Global Tech actively looks to support organizations and activities that share in our desire to help those with engineering backgrounds reenter the workforce. In fact, Walmart Global Tech is sponsoring the Parent and Caregiver Keynote Activity Scholarship at the 2021 Hyperledger Global Forum.

A recent Fortune Magazine story reported workforce participation among women has dropped 57% and may not recover to pre-pandemic levels until 2024. We believe the technology industry needs more women, especially women of diverse backgrounds, to ensure that the technologies we develop and deploy better reflect the customers they serve. Filling this gap is particularly important in the emerging tech industry, where there is well documented gender disparity. In fact, in STEM fields, only 15.7% of engineers and architects are women. Hyperledger Global Forum presents a great opportunity for women to share new ideas and bring knowledge back to their organizations.

Sponsoring the Parent and Caregiver Keynote Activity Scholarship at the event aligns with similar programs within Walmart that create or expand opportunities for women in tech, such as our “returnship” program, Live Better U college degree program, internal “Women In Tech” community groups, sponsorship of the Women in Data Science conference, and more.

The Parent and Caregiver Keynote Activity Scholarship isn’t just for Walmart associates. It’s open to all registered attendees who are also juggling the responsibility of being a caregiver. During the premier enterprise blockchain event of the year, the program will provide engaging online activities — themed immersive mystery experiences — for children ages 5-12 so that parents or caregivers can attend the keynote activities on each day of this important global technical conference. While sponsoring childcare activities may seem a little out of place at a virtual blockchain conference, we know that even the little things like this can mean a lot, especially as associates are balancing the needs of family and career.

Meet me at Hyperledger Global Forum

By David Treat, Global Technology Incubation Lead and Global Blockchain Multiparty Systems Lead, Accenture Blog, Hyperledger Global Forum

I remember the first week of March 2020 well. It was a week filled with awkward elbow bump greetings followed by inspiring conversations and good times with some of my favorite people at the aptly named Corona Ranch. It was Hyperledger Global Forum.

In the hallway chats that ensued after my keynote, Blockchain – What’s next?, there was a common sentiment that the technology was rapidly accelerating, and sense of confidence that we could apply these technologies to prepare the world for potential disruption.

Those conversations were prescient, but who would have ever predicted just how long, broad and deep this global disruption would be?

We didn’t fully imagine what was about to transpire, and yet, with the help of collaboration and technology, we continued moving forward.

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.

This confirms what I know to be true: Hyperledger is at the center of the blockchain ecosystem and you all are leading the way in building real technologies and production systems the world can use to rapidly transform how business is done for massive positive impact.

The Hyperledger community has a long-standing vision for sharing infrastructure to solve real problems. If only they had already been deployed at scale when the pandemic hit. Now, the tech acceleration of the past year proves the world is ready to embrace the possibilities of the technologies we’ve been evangelizing to position most effectively for what comes next.

Hyperledger Global Forum 2021 may look a little different than years past, but the immersive virtual experience will give us the chance to engage with even more people from our global community. We’ve all weathered this massive disruption together – never have I felt more excited to reconnect with you all, build on our existing momentum to solve global problems and roadmap the technical milestones we’ll collectively sprint towards in the year ahead.

Pouring over this year’s lineup of sessions, I’m seeing the following themes come to the fore:

collaborative approaches to coinnovation and interoperability
blockchain endeavors to preserve our privacy and our planet; and,
the future of finance, supply chains and healthcare.

Here is a preview of some of the talks related to the above themes that I am particularly looking forward to attending:

(Coinnovation) How to Create Thriving Ecosystems on Thursday, June 10, at 20:20-20:50 CEST, Accenture’s Melanie Cutlan will discuss different consortium methodologies and how to forge multiparty systems so your ecosystem can thrive long term.

(Interoperability) Hyperledger Cactus Project Updates on Thursday, June 10, at 19:10-19:40 CEST, Accenture’s Peter Somogyvari and Fujitsu Laboratories Ltd.’s Shingo Fujimoto will introduce the Hyperledger project that is solving for interoperability by bridging blockchain infrastructures and constructing distributed management services.

(Privacy) Digital ID: Understanding Perceptions and Expectations on Wednesday, June 9, at 20:20-20:50 CEST, Accenture’s Christine Leong and Alissa Worley will showcase insights from new research on what it will take to drive acceptance and demand for digital identity capabilities.

(Planet) Oceans Plastics Recycling Solution using Hybrid Blockchain on Wednesday, June 9, at 09:40-10:10 CEST, Wipro Technologies’ Hitarshi Buch will demonstrate a blockchain sustainability initiative to incentivize plastic recycling ratings and change the trajectory of the estimated 86 million metric tons of plastic in our oceans.

(Finance) Digital Currency Interoperability with Messages on Thursday, June 10, at 09:40-10:10 CEST, dlt.nyc’s Vipin Bharathan will discuss digital currencies, including central bank digital currency (CBDC) and challenges with interoperability between these systems.

(Supply Chain) Rebuilding Supply Chains into Responsible Supply Networks on Thursday, June 10, at 18:40-19:10 CEST, Accenture’s Tom Fahey & Tal Viskin will explore how sustainability and conscientious consumption have become even more ingrained as top initiatives during the COVID-19 lockdown, and the blockchain-enabled supply network initiatives underway that are meeting those new demands.

(Healthcare) Trading Partner Authentication and Drug Verification in the US Pharmaceutical Supply Chain on Tuesday, June 8, at 20:50-21:20 CEST, LedgerDomain’s Ben Taylor will share the results of a peer-reviewed study that tested ATP authentication and enhanced verification using Hyperledger Fabric to ensure non-counterfeit, safe and effective pharmaceutical drugs.

I hope to see you at these sessions and networking events at Hyperledger Global Forum (June 8-10). With so much great content to choose from, you can use the search function to browse scheduled sessions by the topics that most interest you. If you haven’t registered yet, you can do so here.

As I said after last year’s Hyperledger Global Forum, for me, Hyperledger is a family. It’s a place where I can access friends, experts and colleagues. It’s a place where I can have in-depth conversations, access incredible content, platforms, and share and hear new ideas. If you’re in the blockchain space, attending Hyperledger Global Forum is absolutely essential.

You can visit with me and others from my talented team in the virtual Accenture booth, located in the Expo area. Bring your questions and we can connect live during the event. You can also learn more about Accenture’s work in this important space at Accenture.com/blockchain.
