New to the Hyperledger Labs: Pluggable Hedera Consensus Service

By Blog, Hyperledger Labs

The Hyperledger Labs Stewards recently approved the Pluggable Hedera Consensus Service Hyperledger Lab. The Lab, developed by Hedera with input from Hyperledger Fabric community members and maintainers, enables a permissioned Hyperledger Fabric network to connect to the Hedera Consensus Service running on the Hedera public network. 

For those unfamiliar, Hedera Hashgraph is a public distributed ledger network, operated by the Hedera Governing Council. Council members include Boeing, Deutsche Telekom, DLA Piper, FIS Worldpay, Google, IBM, Magazineluiza, Nomura, Swirlds, Swisscom Blockchain, Tata Communications, and Wipro. The Hedera network supports four publicly accessible network services: Cryptocurrency, File Service, Smart Contract, and the aforementioned Consensus Service.

The Hedera Consensus Service provides an Asynchronous Byzantine Fault Tolerant order of transactions that cannot be manipulated or crash due to the action of any small group of actors. Effectively providing your Hyperledger Fabric network with a verifiable auditable log of all transactions validated by an impartial decentralized network. The plug-in can also enable multiple Fabric networks to receive consensus timestamps from a single, decentralized ordering service.

The plug-in included in the Hyperledger Lab allows the Hyperledger Fabric BYFN (Build Your First Network) sample to connect each Fabric orderer to the Hedera Consensus Service. The orderers submit endorsed transactions to Hedera using the Consensus Service by referencing a common topic ID and independently subscribing to the stream of ordered transactions. The orderers then use the ordered transaction to create a block for their organization’s peer.

Any developer can get up and running with the Hedera Consensus Service today by following the instructions provided in the Lab’s open source GitHub repo: https://github.com/hyperledger-labs/pluggable-hcs/blob/master/first-network/README.md 

It will require a Hedera testnet account, which you can sign-up for at http://portal.hedera.com/. The sample then configures the Fabric network dependencies, connecting the orderers to the public testnet.

We hope that the Hyperledger Lab is only the start of our journey in the Hyperledger community. We’d appreciate any feedback and contributions you have as we look to continue to support users of the Hedera Consensus Service building with Hyperledger Fabric. In the future, we hope to expand upon this plug-in with support for the likes of Hyperledger Avalon and the Blockchain Interoperability Framework.

TSC Approves Hyperledger Cactus as New Project

By Blog, Hyperledger Cactus

Building DLT integration protocol

We are thrilled to announce that the open source Blockchain Integration Framework that Accenture and Fujitsu jointly contributed to Hyperledger Labs has been welcomed as the latest Hyperledger project. With this, the project receives a formal name, Hyperledger Cactus, and also benefits from the resources and promise of longevity that come with inclusion in the Hyperledger Greenhouse.

Key Take-Aways:

  • TSC approves new project – Hyperledger Cactus (formerly known as Blockchain Integration Framework)
  • The move from Labs to the Hyperledger Greenhouse is an important step in the direction towards production-readiness
  • Now is the time for end-user, SI, and vendor developers to participate in defining the architecture of blockchain integration service

In the short six months since entering the Labs, Hyperledger Cactus has attracted significant attention and become a locus of collaboration between developers from our teams at Accenture and Fujitsu, and dozens of others working on DLT platforms both inside and outside Hyperledger. We are very excited to carry this work of establishing an open integration protocol forward, setting our sights on increasing the number and diversity of perspectives and building the community and process maturity in order to graduate from Incubation to Active status as a project.

Why Blockchain Integration?

Innovation in the blockchain space shows no signs of slowing down. This is amazing to see, but when it comes to large scale enterprise adoption today, this rapid pace of change can also be a source of risk. What if the platform I select gets leapfrogged? Or what if I need to conduct business with an ecosystem in the future that’s using a different technology? These questions can manifest in a high stakes decision to choose “the right” solution.

But we live in a world of many networks and databases with differing business requirements. Some need to be fast, some need to store a lot of data, and some need strong resilience properties. As businesses replace traditional infrastructure with multiparty systems, we need blockchain technology to handle a wide variety of possible use cases and requirements. In other words, there will be no “one blockchain solution to rule them all.”

Brian Behlendorf describes this well in his Coindesk 2019 Year in Review: “From here out, the basic business and technical questions – can this be used for real-world use cases?; can competing vendors cooperate on common code and standards? – will be considered more or less answered, with new questions about governance of blockchain networks and interoperability between them taking center stage.”

Enterprises need to be able to confidently move forward with the blockchain platform that best meets their needs today, with the assurance they can integrate, communicate, operate, and transact with any other tech down the road. 

For example, imagine a “fast” blockchain used for processing small-value financial transactions periodically that needs to communicate and even trade with more secure, “slow” blockchains that handle large assets or high-value transactions. Banking-focused blockchains might need to communicate with blockchains that are used to manage real estate. The possibilities and useful applications for blockchain integration services are quite large.

What is Hyperledger Cactus?

Hyperledger Cactus is an Apache V2-licensed open source software development kit (SDK) designed and architected to help maximize pluggability so that anyone wishing to use it to connect any DLT to others can do so by implementing a plugin (please check out the Whitepaper for a detailed technical description). This pluggable architecture helps enable the execution of ledger operations across multiple blockchain ledgers, including Hyperledger Besu, Hyperledger Fabric, Corda, and Quorum available today, with the aim of developers continually adding support for new blockchains in the future.

The beauty of open source, in particular the permissively licensed Hyperledger flavor, means that each entity that writes a plugin can decide whether to contribute it to the community for ongoing maintenance, and to be used by all, or keep it private. In either case, the core Integration Framework will always be available under the Apache v2 license and maintained by the Hyperledger community. Accenture filed two patents on the approach (10,298,585 and 20190253422) and are making the patents available through this code under the Apache 2 license. In our view, the pluggable design combined with Hyperledger governance make this the right solution to the blockchain interoperability challenge.

Why Start in Labs?

We at Accenture and Fujitsu realized the market need for blockchain integration independently and quickly realized the opportunity to collaborate. Accenture began working on the blockchain interoperability challenge in 2018 and realized that long-term success hinged on building a broader ecosystem around the project, which led to open sourcing this work to Hyperledger Labs in November 2019. Fujitsu came aboard as key collaborators at last year’s Hyperledger Tokyo Member Summit and contributed the ConnectionChain codebase in December 2019. Then, the two companies considered a unified architecture based on the two code bases. The results are described in the white paper.

Hyperledger Labs provides an easy way to test the technical and community viability of potential new Hyperledger projects. It’s a valuable initial step to determine interest prior to undertaking the significantly more intense process of proposing a new Hyperledger project.

It didn’t take long for interest in Hyperledger Cactus to emerge. Following our joint presentation at Hyperledger Global Forum 2020 in Phoenix, several people from academia and enterprises expressed interest in working on this project. Thus began the conception (and name!) of Hyperledger Cactus. While it’s always gratifying to hear positive feedback, the real test of a project’s viability is when people roll up their sleeves and make contributions, be they code, documentation, or perspective.

A PhD student pursuing a summer internship at Hyperledger focused their research on the topic of ledger-to-ledger migrations. And developers at Accenture, Fujitsu, and several other organizations are working on converging the code bases into a unified core system. For two independent teams of enterprise engineers (Accenture and Fujitsu in this case) to separately arrive at the need for an open source solution to address the challenges of cross-ledger system transactions validates both the size of the problem space and the veracity of the Hyperledger Cactus approach to addressing it.

What’s Next?

As Hyperledger Cactus joins the other 15 Hyperledger projects in the greenhouse, our number one priority is to grow the community. Always a goal of open source projects, we feel it is especially important for Cactus now so that we can obtain ideas from as broad a cross-section of the blockchain community as possible and get them built into the architecture of the project from the start.

Our first effort as a community will be to finalize our modular, pluggable interfaces so that all stakeholders in Hyperledger (and others outside Hyperledger that wish to participate) can benefit from our solution for blockchain interoperability. A diverse community is an important first step to assuring innovation continues to flourish across this dynamic space, helping it to both scale and achieve its  potential across a global network of ecosystems.

And don’t let the name fool you – the Cactus community is not at all prickly 😊. On the contrary, we are extremely open and all are welcome! You don’t have to ask to ask. Please jump into the conversation on our Chat channel, check out our repo, read the contributing document, attend our meetings, and together we can build a modular, extensible system that makes it possible to easily incorporate and integrate new blockchains as they get developed.

Hyperledger Community on Camera: “How to Get Involved” Video Series – Part II

By Blog, Special Interest Group, Video

While the Hyperledger community was gathered in Phoenix at Hyperledger Global Forum, many members took the time to sit down, on camera, and explain what happens in the array of Hyperledger working groups, special interest groups (SIGs) and technology projects. These videos are great introductions to the community-driven activities in the Hyperledger ecosystem. Geared towards anyone looking to take on a more active role in the effort to advance open source enterprise blockchain, the “How to Get Involved” video series provides an overview of the goals, key initiatives and target use cases each for each group or project. The message in each case is that you are invited to join and all are welcome here.

A 21st Century Model for Collaboration

By Blog, Hyperledger Fabric

The first two decades of the 21st century have seen enormous challenges on scales never before encountered. Whether a global recession or global pandemic, good information management is an essential tool for decision‐making processes, strategic and operational, at every level. But dramatic changes in news media and the proliferation of misinformation, along with outdated (scientific) research frameworks, are impeding timely use of critical data assets, which are at the center of any effective systemic response. This extends to successful emergency preparedness and response and is as much a human-centric problem as a data-centric one. At heart is this question: how do we share massive quantities of data to coordinate on effective responses to global crises?

Finding good ways to use big-data efficiently for solving real world problems touches almost every industry, from finance to education, and from insurance to supply chain management. With globalized industries now much more reliant on data-driven processes, two pivotal problems have emerged: insufficient infrastructure to securely manage big-data resources, compounded by a “trust gap” in the reliability of that data. In both cases, blockchain and distributed ledger technologies offer meaningful solutions to positively transform information dependent industries, and the ways we collaborate with one another on shared goals.

The exponential growth of fake content and disinformation represents a major trust gap, and points out inherent design issues in the architecture of the Internet that need to be addressed if we wish to safeguard trust and the legitimacy of information resources. Blockchain and distributed ledger technology resolve some of these flaws, offering solutions to security vulnerabilities, privacy issues, and data authenticity. While many blockchain applications tend to center on finance, at Penta Network the focus is using distributed ledgers for data related problems in multi-stakeholder ecosystems. Our goal is to facilitate peer-to-peer and multi-peer collaboration through digital networks based on trusted data.

As a first step towards that goal, we launched a social impact initiative called Trusted Voices in 2018. The Trusted Voices project is based on Hyperledger Fabric and other blockchain technologies to provision a chain of custody for information and media assets. The purpose of the project was to demonstrate authentication of digital content at time of original publication, and subsequent tracking across digital platforms, including social media.  A robust chain of custody enables consumers to track content and trace information assets back to their authors and origins. Content traceability offers a powerful tool to combat the proliferation of inaccurate or unauthorized content, while concurrently protecting the intellectual property rights of the authors. There are broad opportunities for this technology: from flagging and removing fake news and disinformation, to collaborative networks based on shared content. Trusted Voices establishes the possibilities for both, and more. 

As an initial test of Trusted Voices, in 2018 Penta visited one of the Central American migrant caravans sheltering in Tijuana, Mexico. The pilot conducted interviews with refugees and immigration officials, and even filmed the first official interview with the Honduran Ambassador to Mexico from an English language platform. Trusted Voices successfully deployed blockchain technology to provide proof of publication for media content, and then used tracking pixel technology to follow that content across platforms. It also highlighted some key values of using Hyperledger technology, such as verifiable, timestamped event histories. With the success of this trial, Trusted Voices showed how content chain of custody will play an important role in the digital transformation of news media and journalism by enabling consumers to verify for themselves the authenticity of media content. 

Trusted Voices has since expanded, and Penta Network is currently developing related technologies for scientific research. In part, the need comes from academic institutions having delegated citation management primarily to commercial publishers. In response, there is a growing movement for an open publishing model, which seeks to return authorship and citation responsibilities to universities and the public. Blockchain has the capacity to accomplish this, while at the same time fostering innovative models for large-scale collaboration. Without undercutting the commercial interests of publishers, tracking and verifying all inputs to research projects blockchain can safeguard researchers’ individual contributions and facilitate multi-party collaborations. In other words, this approach offers a digital blueprint for crowd-sourcing human collaboration.  

Supporting collaborative work models with blockchain technology has real impact, not just on conducting basic research, but also on the knowledge and products that flow from that research. It offers substantial improvements over current models, where some academic and medical research institutions might hoard their data and results, in order to compete for lucrative grants and patents. Distributed ledger systems can serve as trusted data alternatives to private information silos, inviting pioneering researchers and business innovators into more collaborative efforts to rapidly progress and distribute the benefits of their work. As Covid-19 has shown, microscopic pathogens move much faster than patent law and peer-reviewed research. With blockchain technology comes hope of significantly shortening the time from research to discovery, and from discovery to commercial production. 

Whether facing a global pandemic, climate change, or a worldwide economic recession, 20th century business models that encourage working in seclusion and an atmosphere of competitive winner-takes-all attitudes do not fit with the enormous 21st century challenges we face. Instead, we need to rethink, reinvigorate and re-innovate human collaboration for the new century. 

The Hyperledger ecosystem has an opportunity to play a leading role in creating 21st century models for communication and collaborative work that operate at large scale. By helping to overcome many of the obstacles limiting our ability to work together as global digital citizens, blockchain is shining light on new operating frameworks for peer-to-peer and multi-peer cooperation. Key to their success will be secure, verifiable, and shared information assets. Trust in that information has never been more important, and blockchain empowers all communities to share their trusted voices.

Identity Applications in Action & Powered by Hyperledger

By Blog, Hyperledger Fabric, Hyperledger Indy, Hyperledger Sawtooth

Digital identity is gaining a lot of traction as a driver for blockchain adoption. There is growing recognition across many markets that reshaping how digital information is managed and verified can simultaneously increase online trust and privacy. The Hyperledger community is working hard to develop and deploy blockchain-enabled identity technologies and solutions with an eye towards decentralizing control of information and creating new models for verifying identities. 

To illustrate where this technology can take us, we are showcasing some applications where it’s already being put into action:

Known Traveller Digital Identity

Known Traveller Digital Identity, or KTDI, is a World Economic Forum initiative with Accenture that brings together a global consortium of individuals, governments, authorities and the travel industry to enhance security in world travel. The pilot leverages cryptography, blockchain technology and biometrics and aims to allow cross-border travel without presenting physical documents, accelerating the flow of passengers through airports, improving passenger experience, and enabling authorities to better focus limited resources on security improvements.

QDX™ HealthID platform 

QDX™ HealthID platform is a service from Quantum Materials Corp that leverages self-sovereign identity technology to provide end-to-end visibility to support testing and immunization for infectious diseases, including COVID-19, at scale. The platform enables multiple methods of authenticating the individuals being tested, those who are administering the test, as well as the test kits themselves, whether to detect the presence of the virus itself or associated antibodies. 

The QDX™ HealthID platform uses Hyperledger Sawtooth as the backing distributed ledger technology, which is deployed and managed using Blockchain Technology Partner’s platform Sextant for Sawtooth. The platform is also readied for integration with other distributed ledger applications via DAML, the smart contract language open sourced by Hyperledger member, Digital Asset.

MemberPass

Provided by CULedger, MemberPassTM is a digital credential held by credit union members that protects credit unions and their members from identity theft and fraud in all banking interactions, from call center authentication to lending to new account opening. MemberPass is a simple, secure replacement for user IDs and passwords, and supplants the traditional knowledge-based interrogation contact centers employ today to authenticate members calling for telephone banking services. MemberPass seamlessly authenticates both, the member and the credit union to each other, in any call-in, log-in or walk-in exchange, providing a consistent, frictionless experience across all channels. 

Sovrin Network

Operated by independent Stewards, the Sovrin Network uses the power of a distributed ledger to give every person, organization, and thing the ability to own and control their own permanent digital identity. With recent advancements in digital identity standards, Sovrin provides a secure and private network for identity holders to collect, manage and share their own verifiable digital credentials.

The Sovrin Network is governed by The Sovrin Foundation, a nonprofit organization established to administer the Governance Framework for this open source decentralized global public network enabling self-sovereign identity on the internet. 

Trust Your Supplier

Trust Your Supplier is a production Hyperledger Fabric blockchain network, running on the IBM Blockchain Platform, that provides suppliers with a trusted digital passport to streamline on-boarding with their customers.

The Trust Your Supplier network is a cross-industry source of supplier information and identity helping to simplify and accelerate the on-boarding and lifecycle management process. TYS was built to be a cross-industry blockchain network to facilitate procurement functions within an organization. The network’s first use case is focused on supplier onboarding and validation.

VerifiedMe

Verified.Me is a service offered by SecureKey Technologies Inc., in conjunction with a consortium of seven of Canada’s major financial institutions – BMO, CIBC, Desjardins, National Bank of Canada, RBC, Scotiabank and TD. Verified.Me is a privacy-respecting digital identity and attribute sharing network. The service simplifies identity verification processes by allowing individuals (subjects) to share identity and attribute information from trusted sources (including financial institutions, mobile operators, credit bureau, and government) with the services that they wish to access.

The network is based on permissioned distributed ledgers operated by the consortium. It is built using the IBM Blockchain Platform which is based on Linux Foundation’s open source Hyperledger Fabric  and is aligning with W3C decentralized identity standards, to enable interoperability with other networks. SecureKey’s Triple Blind® approach means that no network participant alone, including SecureKey, can have a complete view of the user journey – the subject can’t be tracked.

The service is free for consumers to use, either using their web browser, or by downloading the mobile app through the App Store (iOS) or Google Play (Android).

Join the conversation about blockchain-based identity technologies and solutions with #HyperledgerIdentity this month on social channels. Also, Hyperledger has an Identity Working Group that is open to all. Learn how to get involved via this video.

Minifabric: A Hyperledger Fabric Quick Start Tool (with Video Guides)

By Blog, Hyperledger Fabric, Video

Hyperledger Fabric is the clear leader in permission based blockchain frameworks. It has become the de facto standard for enterprise blockchain platforms. Its performance and data privacy capabilities are second to none in the very crowded blockchain fields. However, its powerful capabilities come with some challenges in its deployments, implementations and understanding, especially for those who are used to other blockchain systems such as Bitcoin and Ethereum. 

It does not have to be that way. With the right tooling, one can easily deploy Fabric networks, learn how Fabric works, understand the life cycles of Fabric artifacts and become an expert as a Fabric network administrator or chaincode developer. With these goals in mind, I created a tool named Minifabric that allows you to easily setup a Fabric network, expand your network, install and upgrade your own chaincode, invoke transactions, inspect your ledger, and change configurations of your channel. By going through these tasks using Minifabric, you can gain valuable skills and a complete understanding of Hyperledger Fabric.

Minifabric comes as a 10-line bash script (for Linux and OS X) or 30-line batch script (for Windows) and is available on github.com under Apache 2 license. You can get started with Minifabric to start your Hyperledger Fabric journey by simply following this README. To further aid the people using Minifabric, I’ve also made a series of videos to demonstrate how you can accomplish various tasks.

  1. Quick Start
