The Hyperledger Global Forum Community Fair: Where to connect with people who share your interests

By David Boswell, Senior Director, Community Architect, Hyperledger Foundation Blog, Hyperledger Global Forum, Regional Chapter, Special Interest Group, Working Group

It has been over two years since we had a chance to get together in person and connect with Hyperledger community members from all over the world. Since Hyperledger Global Forum 2020, there have been hundreds of opportunities to meet online in calls and during virtual events, but those virtual interactions are just not the same as connecting with someone in real life.

The “hallway track” of a conference – the time in between sessions and other parts of the formal schedule where you walk around and meet new people and reconnect with friends and colleagues – is often people’s favorite part of an event. This informal opportunity to engage is what has been so hard to reproduce virtually (the Zoom breakout rooms, 2D and 3D online spaces and other attempts were worth trying but just aren’t as effective) so we are really looking forward to this part of Hyperledger Global Forum (HGF) this year.

To help people connect at HGF (#HyperledgerForum), we’re trying something that has been used in community events that Mozilla has run in the past. These community events were helpful in bringing people with similar interests together. For instance, you may be really interested in what is happening with blockchain in the telecom industry or you may want to speak in Spanish to someone about what is going on with deployments in Latin America, but you don’t know who to speak with as you’re walking around the event.

In order to help you find the right people to connect with, we’ll be setting up a Community Fair in the Expo Hall. The Fair will have a series of table tops manned by people from different parts of the community who are interested in meeting and talking with you. This will include people from our Special Interest Groups who are implementing Hyperledger projects in a range of different industries, people from our Regional Communities who are traveling in from all over the world, and people from our Working Groups who are exploring technical questions about distributed ledgers.

The goal of HGF is to create an event where community members from around the world can meet, align, plan and hack together in person. The sessions, workshops and other parts of the formal agenda will be very useful to help you do just that. We hope that the Community Fair will be another great addition to the formal part of the agenda.

Groups planning to participate in the Community Fair:

Regional Chapters

Brazil Chapter
India Chapter
Latinoamerica Chapter
Japan Chapter

Special Interest Groups

Climate Action and Accounting SIG
Telecom SIG
Financial Markets SIG
Media and Entertainment SIG

Working Groups

Learning Materials Development WG
Performance and Scale WG
Identity WG

Community Events

Hyperledger Challenge winner

Registration details for HGF are here. We hope you’ll join us and make the most of the Community Fair. Its goal is to make it easier for our community members to make valuable connections and find people and resources that align with their interests and needs, regardless of where they are in their enterprise blockchain journey.

Developer showcase series: Daniel Bluhm, Indicio

By Hyperledger Blog, Developer Showcase, Hyperledger Aries, Hyperledger Indy, Identity

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Daniel Bluhm, Software Engineer at Indicio.

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

I am currently working on Hyperledger Aries Cloud Agent – Python and other agent implementations. I spend most of my days working on agents and protocols. I first got into blockchain at the Sovrin Foundation where I got my start as an associate software engineer. I was actually around at the founding of the agent ecosystem, back when we all collaborated in the Hyperledger Indy Agent Working Group. I was one of the first implementers and continued working with it as the community grew. Eventually it snowballed into the Hyperledger Aries project.

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 really like where things are going with the Aries Cloud Agent – Python repo, driving towards more pluggability and making it so we can extend functionality without changing the core project itself. I am also excited to get did:indy method support into Hyperledger Indy, as well as multi-ledger support in ACA-Py.We already have reads down, so now we’re just working on the writes.

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

We have a really diverse and thriving community in the Hyperledger Aries space; what we really need going into 2022 is a push for greater adoption of the technology and getting it into the hands of people who aren’t engineers. I would also really like to see a focus on encouraging more interaction with the Hyperledger Indy project, especially after seeing how positively this affects our work with Hyperledger Aries.

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

The biggest piece of advice I could give is to not be afraid to step in, contribute, and break stuff. It doesn’t matter if your pull request isn’t perfect.The maintainers of the project will work with you to get it right.

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?

The technologies that are most interesting to me are the ones that allow us to use multiple different technologies at the same time – which is exactly what we’re striving for in Hyperledger Aries. This enables us to take advantage of the strengths of one technology – be it blockchain, communication, protocol, crypto suite, or something else – and use those strengths to shore up the places where another technology might fall short. Beyond that, anything that makes it easier and more efficient for the end user will be a huge step in the right direction.

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

The biggest problem that I would like to see blockchain solve is power imbalances. This applies across the board, to finance, representation in government, data used and collected by big orgs, and other scenarios we just haven’t thought up yet. I’d like to see blockchain enable individuals to have a say in how they are treated and be more self-deterministic – they should have at least some level of control over what’s running their lives.

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

I would like to see Hyperledger and blockchain technology in general in the hands of real people. They don’t necessarily need to be aware that they are using a blockchain. In fact, I think there are some really good arguments to the contrary. But it should be a positive influence in their lives as it is used day to day. I would like to see the blockchain space settle down, drop some of the hype, and just be used for what it’s good at.

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

No one gets it right on the first try. Don’t be afraid to make mistakes, break tests, crash CI/CD pipelines, or push broken code. Don’t do it intentionally, of course, but the faster you can get at shortening the “experience a failure, find the problem, implement the fix” cycle, the faster you’ll learn and master your code. In short, don’t be afraid to break stuff. Just give it a shot and learn from the result.

When a problem or change needs to be made in the future, the developer then can see what your thought processes were for writing the code you did.

What technology could you not live without?

I could not live without Git. Without it it would be nearly impossible to get any code written and submitted. It’s part of my everyday workflow and even crucial in my hobby projects.

Introducing Hyperledger Aries Framework JavaScript 0.2.0

By Karim Stekelenburg, Hyperledger Aries Framework JavaScript Maintainer and Animo Solutions Co-founder Blog, Hyperledger Aries, Identity

About half a year before we started Animo Solutions, my co-founders and I discovered Hyperledger Aries Framework JavaScript, an open source JavaScript/TypeScript framework designed to create interoperable self-sovereign identity solutions. At the time we were just getting acquainted with the concept of SSI. Just the idea that we could use TypeScript to build made our lives so much easier and the tech so much less daunting. It turned into one of the building blocks of our company, and I would end up becoming a maintainer and strong advocate of Hyperledger Aries Framework JavaScript. Now, after two years of hard work by the community, we’re excited to announce the 0.2.0 release of the framework. In this article, I’ll take you through what this newest release entails and why it will change the way self-sovereign solutions are built.

Hyperledger Aries Framework JavaScript (AFJ) is a framework written in TypeScript for creating interoperable self-sovereign identity (SSI) solutions. The framework has two main focus points. It aims to be as accessible as possible for any developer whether new or experienced in the world of SSI. It is also designed specifically for multi-platform development, so both server-side and mobile solutions can be built with the framework.

The framework has gained a lot of momentum lately. The community has been growing quickly with various governments and organizations stepping in. Our current contributor count is 37, and the working group calls now have around 10 active participants (as opposed to the two we had two years ago). The potential of the framework has become clear to developers other than us (the fanatics). For example, at Animo we recently received funding from the EU NGI eSSIF-Lab initiative to lift the framework to the next level regarding mobile development options.

The new Hyperledger Aries Framework JavaScript release (0.2.0) contains some incredible steps forward. Especially in our goal to make the framework AIP 2.0 compliant. AIP 2.0 compliance will not only ensure the framework supports the latest standards and protocols, but it will also greatly increase interoperability and make it more useful outside of the Hyperledger Indy ecosystem. Specifically, this release contains:

Full support for the out of band and did-exchange protocols
Postgres wallet support
- Previously the framework only supported SQLite. This addition ensures the framework is better suited for cloud infrastructure.
Wallet import/export support
- This addition enables users to migrate their wallet data to and from other Hyperledger Indy-based wallets.
Pickup protocol v2 for better control over interactions with the mediator
Support for the issue-credential-v2 protocol
- The issue credential and present proof v2 extend the framework with the ability to support multiple credential and proof formats. Instead of adding a separate API for the v2 protocols, we have put a lot of effort in designing a single, easy-to-use API that works with both versions and is extensible for later versions in the future. In the next release we’ll be adding support for the present proof v2 protocol.
Credential revocation and revocation notifications for holders and verifiers
- This allows holders to prove that a credential hasn’t been revoked and verifiers to verify this. The revocation notifications allow the holders to be informed about the fact that one of their credentials has been revoked, rather than discovering this when trying to present proof.
Full did:peer support
A generic DID resolver that currently supports did:key, did:web, did:sov and did:peer.
An upgrade assistant to help users update their wallets to newer versions of the framework
- As the framework evolves over time, some of the underlying data structures may change. With the upgrade assistant, we aim to make it as easy as possible for users to migrate.

We’re already working hard on version 0.3.0 that will, just like the 0.2.0 release, be packed with new features such as support for the W3C Verifiable Credential Format and BBS+ Signatures 2020, making the framework fully AIP 2.0 compliant.

Check out the 0.2.0 release here and the update instructions here. For general documentation, please see aries.js.org.

If you’re interested in Hyperledger Aries Framework JavaScript and its developments, we recommend you join the working group call (07:00 MT / 14:00 UTC on zoom) and check out the GitHub repo. If you want to discuss building a solution with the framework, feel free to reach out to me at karim@animo.id.

For hands-on experience with AFJ, join us at Hyperledger Global Forum (HGF) for the half day workshop: How To Build a Self-Sovereign Identity Agent With Hyperledger Aries Framework JavaScript.

#HyperledgerPayments: Applications Making Financial Transactions Easier, Faster and More Accessible

By Hyperledger Blog, Finance, Hyperledger Fabric, Hyperledger Iroha, Hyperledger Sawtooth

Bitcoin, Ethereum and other altcoins have sparked a range of investments, industries and even emotions. However, there is a fast-growing array of digital currencies and electronic payment systems that are focused specifically on leveraging distributed ledger technologies to make fundamental financial transactions easier, faster and more accessible both at the wholesale and retail level. As this recently released ebook details, central banks around the world are exploring ways to leverage different Hyperledger DLTs to introduce Central Bank Digital Currencies (CBDCs). However, there is #HyperledgerPayments action happening on a number of fronts and leveraging a mix of Hyperledger technologies.

Below, we highlight a few of the Hyperledger-based applications that are already in the market, rewriting the rules for how money and value are delivered, stored and spent. This sampling showcases the global reach of both Hyperledger technologies and blockchain payment systems:

Bakong

Sponsored by the National Bank of Cambodia, the country’s central bank, Bakong is the first retail payments system in the world using blockchain technology. Built on Hyperledger Iroha, Bakong delivers value for customers, merchants and banks. Individuals can now transfer money and buy from merchants with a simple smartphone app. Merchants gain a fast, cashless, and secure payments system. And banks can do interbank transfers at much lower cost.

Bakong was developed by Soramitsu and, after a soft launch in 2019, now has nearly 40 financial institutions (and counting) using the system. The project was also designed to promote financial inclusion for the country’s large number of unbanked citizens. Any citizen of the country can open a Bakong account, even if they don’t have a traditional bank account. The more than 500 merchants that accept Bakong can be viewed in a map inside

Byacco

Soramitsu also created a local payment system for the University of Aizu, Japan, based on Hyperledger Iroha – technology that was originally developed within the walls of the University. Byacco is an app that students use to add and access digital money to pay local goods and services, split bills at the university cafeteria and stationary shop and send and receive money with a low (1 ¥) fee.

Kate Coin

KBC bank in Belgium has introduced blockchain-based Kate Coin to customers using its KBC Mobile app. Powered by Hyperledger Fabric, Kate Coins are issued to customers as loyalty rewards. To start, the Kate Coins can be used to pay for banking and insurance services. However, the goal is to scale up its use through partnerships with business customers and other third parties that want to reach KBC Mobile app users, first in Belgium and then across the HBC group.

Twig

To help drive the circular economy, UK-based Twig has created a system that allows consumers to turn their pre-owned electronics, clothes and other goods into cash. Users are paid for their goods via Hyperledger Sawtooth-based Twig Pay, where they can see incoming payments and tap into the cash for purchases and transfers.

Join the conversation about solutions and applications in the financial service market with #HyperledgerPayments on social channels. For a deeper dive, join us at Hyperledger Global Forum 2022, September 12-14 in Dublin, Ireland. Sessions will include:

A Hyperledger Fabric-based Programmable Money Platform – Robert van Donge, IntellectEU & Dirk Hermans, KBC Group

Hosted Discussion: Private Credit on Blockchain – Anshuman Asthana, Marketnode

Saudi Aramco, Procure to Pay Eco-System – Ali Safri, Avanza Innovations & Abdullah M Askari, Saudi Aramco

US Digital Currency: Opportunities, Challenges and Strategies – Jim Mason, DTCC

Hands-on-Workshop: Moving Central Bank Digital Currency from Conception to Reality with Hyperledger Technologies – Elli Androulaki & Angelo De Caro, IBM

Developer showcase series: Dr. Yunxi Zhang, Accenture

By Hyperledger Blog, Developer Showcase, Hyperledger Aries

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Dr. Yunxi Zhang, Tech Architecture Delivery Associate Manager at Accenture.

回到我们的开发者展示系列，让我们了解现实世界中的开发者如何使用超级账本技术。这次为我们分享的是来自埃森哲的技术架构师助理经理：张赟熹博士 (Dr. Yunxi Zhang)。

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

I’ve been working on a number of blockchain projects across various blockchain platforms for diverse business cases since I joined Accenture. I am fascinated by the core blockchain technology, which was invented as a main technical product of bitcoin. I look forward to helping our clients better understand how blockchain could potentially shift their businesses to be more productive. My main motivation for working with blockchain is to help clients leverage this technology to achieve their goals.

问：您好，张博士！您可以介绍一下您的工作背景以及您是如何加入区块链领域的：

自加入埃森哲后，我已经参与了很多个和区块链相关的项目。基于每个项目有其独特的业务，我们会选用不同的区块链平台。区块链作为比特币的一个主要的技术产品，我深深被其吸引。同时，我也期待使用区块链来帮助我们的客户更好地理解如何可以使用这项技术帮助转型他们现有的业务，使其更富有成效。达成这些愿景成为了我在区块链这个领域工作的主要动力。

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

Hyperledger Aries is currently the main framework I’m working on in my project. I’ve used Hyperledger Fabric in earlier projects as well.

We’ve successfully built up a demo by using Hyperledger Aries to demonstrate how Self-Sovereign Identity credentials could help simplify an entire process from credentials issuance, presentation and verification to make a business process more efficient and productive.

Overall, I’ve found the documentation of Hyperledger Aries to be always evolving to include the up-to-date key design principles as well as both technical and business benefits. For Aries, there are even online courses available that introduce the big picture first. If people would like to know more low-level details, there is abundant documentation available in the repo. It’s common for the documentation to be a bit behind the technology. To deal with this challenge, the open community is very responsive to new joiners, listening to us patiently and reacting to any questions and issues raised. This helped me delve into Aries in a short period of time. Once I have a very good understanding of how the technology works, I’m glad I can contribute back to Aries in different aspects.

问：您在项目中使用了哪些超级账本的框架或工具？有什么新进展可以跟大家分享吗？您能总结一下您使用超级账本技术的经验吗？

Hyperledger Aries是我目前项目中主要使用的框架。除此之外，我之前的项目中也曾使用过Fabric。通过使用Aries，我们成功地搭建了一个演示用以验证如何通过使用用户自主身份凭证来简化凭证生成，凭证提交以及凭证验证，使得整个业务流程更富有成效。总体来说，我发现Aries的文档始终保持持续更新的状态，及时发布最新的技术信息，关键设计原则以及业务效益。Aries甚至提供了网上课程，介绍了Aries的整体情况。同时，Aries的代码库中提供海量的细节信息。文档的滞后性是常态，为了解决这个问题，Aries的开放社区对于新加入成员提出的问题给予及时的回复，耐心聆听我们的意见。这使得我在很短的时间内理解Aries。当我对Aries有足够的理解后，我很高兴可以以各种方式回馈于Aries。

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

Hyperledger Foundation should focus on providing updates on how the more mature Hyperledger technologies are being leveraged in different production environments. Any technical architecture design examples could be shared in each repo to help boost the technical architects and developers to try them, so we can reuse these designs, help improve them and contribute back to them. This could facilitate the pace of the adoption for each Hyperledger technology even more.

问：您认为超级账本基金会今年重点应该聚焦在哪方面？

Hyperledger Foundation应该更关注于更新每个Hyperledger技术的成熟程度，它们如何应用于生产环境中。任何的的架构设计的案例可以共享于代码库中，这样，技术架构师和开发人员可以直接尝试并进行改进，并回馈于每个技术。这样也许可以更有效地加速Hyperledger技术的应用。

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

Hyperledger technologies are built upon the basic concept of how blockchain works, but they each implement it in its own ways to provision enough flexibility for different use cases. The nature of blockchain is very complex as it is comprised of different areas of technologies such as cryptography and distributed systems. It would always be beneficial to developers to grasp this foundational knowledge prior to starting to use Hyperledger technologies.

问：您会给其他有兴趣开始使用区块链的技术人员或开发人员提供什么建议？

Hyperledger的技术是构建在区块链的基础概念之上，但是它们各自有自己的实现方式，这样使得他们能更灵活地应用于不同的用户场景中。区块链是复杂的，因为它包含了很多不同的技术，比如加密学，分布式系统等等。对于程序员来说，理解和掌握这些底层的知识对于使用Hyperledger的技术是非常有益的。

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 see use cases related to decentralized Identity and self-sovereign identity being some of the most interesting and popular business areas in the future. Hyperledger Aries and Hyperledger Indy are already contributing to making this happen more easily.

问：随着超级账本项目的不断成熟，您认为由此产生的最有趣的技术、应用程序或用例是什么？

我发现目前一些比较流行的商业领域，他们的用例已经关注了去中心化身份以及用户自主身份，并且会在今后变得越来越流行。Hyperledger Aries和Indy在这些领域里起到了关键的作用，使得应用变得越来越简便。

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

Due to blockchain’s innate intricacy, the application of it is not always straight forward. Even developers or architects with many years of experience find it a challenge to design and use blockchain within the underlying infrastructure and system architecture around them. So, to have a PaaS service of blockchain (not only including the underlying blockchain network, but common architecture on top of it) to quickly enable technicians to use them quickly could further boost its application in all aspects.

问：您希望区块链能解决的一个问题或者一件事情是什么？

By Hyperledger Announcements

Releases Details of New Hyperledger Besu Execution Client Incentive Program

SAN FRANCISCO and AUSTIN (June 10, 2022) – Today, at Consensus 2022, Hyperledger Foundation, the open, global ecosystem for enterprise blockchain technologies, announced seven new members, including Avast, Infosys, The Digital Dollar Project and the National FinTech Center at Morgan State University. During Consensus 2022, Hyperledger Foundation will be highlighting the widespread enterprise adoption and commitment to open source blockchain technologies. Attendees can visit the Hyperledger Foundation booth (623) to learn more about the recent inclusion of Hyperledger Besu in the Ethereum Foundation’s Execution Layer Client Incentive Program, new project milestones with various projects including Hyperledger Cactus and Hyperledger Firefly and more.

Hyperledger Foundation exists to foster the community-development of enterprise-grade blockchain software that will reshape commerce, currency, communications, identity and more. For that reason, the Ethereum Foundation (EF) has opted to include Hyperledger Besu in the Execution Layer Client Incentive Program (ELCIP). The program will provide execution-layer client teams with locked ETH in the form of live validators to be released according to certain milestones, including post-merge performance and progress towards enabling withdrawals from the beacon chain. The client incentive program is a strategic investment by the EF to engage the Hyperledger Besu community in ensuring a diversity of clients and overall health of the network.

In a further indication of the commitment to open source software in the enterprise market, Avast is joining Hyperledger Foundation after acquiring two Hyperledger member companies, Evernym and SecureKey. Both companies have been long-time contributors to Hyperledger and integrated the technology into the core of their businesses. A recent case study with Bosch focused on the company’s strategic process for developing open source technologies and how that led to Hyperledger Lab Perun. In another case study, Hitachi shares the ROI of implementing a Hyperledger-based solution to streamline its own internal procurement process, putting the open source software it helps develop to work to better its own business.

“As we move towards an increasingly decentralized future, the role of openly developed and governed enterprise blockchain technologies will only grow in importance,” said Daniela Barbosa, Executive Director, Hyperledger Foundation, and General Manager Blockchain, Healthcare and Identity at the Linux Foundation. “We see more and more of our technologies being adopted and adapted to support new business models, creating opportunities for new developers and driving innovation at companies of every size.

Hitachi Shifts to Paperless, Secure Procurement Contracts with Hyperledger Fabric

By Hyperledger Blog, Hyperledger Fabric

Read the full case study here.

Paper pushing. It’s synonymous with tedious, slow processes. Yet often, the pushed paper is vital to a company’s business. And contracts are especially important paper.

But digitizing a contract process isn’t as simple as it sounds. As the contract moves between parties, there’s a risk of tampering. Or mismanaging version control.

Many companies continue to use paper for their contracting processes to maintain security and trust. The procurement divisions of Hitachi, Ltd. were no different.

Hitachi is a Japan-based global technology organization. It focuses on digital innovation in the mobility, smart life, industrial, energy and IT sectors. The company has 873 companies across more than 100 countries with 380,000 employees worldwide.

At such a scale, Hitachi’s procurement divisions process thousands and thousands of contracts every month. That’s a lot of paper. That’s also a lot of time managing that paper.

Hitachi’s Service Delivery Division develops tools to help increase business efficiencies. It saw this as a perfect use case. Ultimately, an improved procurement process would help companies within the Hitachi group and their clients.

The team set about creating a secure contract management system. For eight months, they worked with procurement personnel to develop the solution. First, they needed to understand the paper process as it was working. The team considered how the process could be more efficient while also keeping the security and integrity of the documentation in place.

They chose Hyperledger Fabric, an open source blockchain framework from Hyperledger Foundation. Hitachi had already created blockchain-backed frameworks on Hyperledger Fabric in its financial and industrial areas, so the team members knew it could provide the advanced security needed for critical document processing.

The procurement division of Hitachi’s head office tested the new paperless, blockchain-backed, Electronic Signature Service (ESS). This division manages the contracts with 2,000 business partners.

It began digitally processing all new contracts in July 2021. Under the old paper-pushing method, the division processed about 333 cases per month. Now it is processing at least 400 contract cases per month — a 20% increase. And though they’re processing more cases, they’re doing them in less time than before. Division personnel now have time to focus on other important tasks like investigation, negotiation, and engaging with new contract companies.

The Hyperledger Foundation team worked with Hitachi on a case study that details the goals, approach and results of implementing this blockchain-backed, paperless procurement solution as well as plans to roll it out to all the procurement divisions. These divisions manage the 3,500 companies contracting with the Hitachi Group.

Hyperledger Ursa code review

By IDLab Blog, Hyperledger Ursa, Identity

(Le français suit l’anglais)

Hyperledger Ursa is a shared cryptographic library used to avoid duplicating cryptographic related code. The library is an opt-in repository (for Hyperledger and non Hyperledger projects) to place and use crypto.

Broad deployment of digital identity will depend on strong security to deliver the high levels of assurance required in many consumer transactions with their governments, their financial institutions, and other trusted organisations.

Leading advancements in decentralized identity, several originating in Canada, rely on the Hyperledger family of technologies. As such, Hyperledger Ursa is a central component depended upon to provide the security overlay for decentralized identity.

Rooted in a “trust but verify” mindset, several Canadian public sector entities and Interac (Canada’s interbank network) sponsored a project at the Digital Identity Laboratory of Canada (IDLab) to perform a security and cryptography code review of Hyperledger Ursa (full report is available here).

Those commissioning this project deemed it important to have an arms-length third party assessment of this foundational component of the Hyperledger family to understand the risks (if any) being assumed with the deployment and use of Hyperledger-base technology in the domain of decentralized identity.

Overview of Hyperledger Ursa library code review scope:

A code review that examined:

Entry points
Coding standards
Data storage and transfer
APIs and their security
Third party library usage
Programming language issue
Logic flaws

Cryptography best practices including examination of:

Cryptography and key management
Entropy
Best practice cryptography usage

The review did not include an assessment of the cryptographic algorithms foundation themselves, or their suitability. Examination was limited to assessment of sound implementation within Ursa.

Following the code review and the findings documented, the IDLab team worked closely with key Ursa contributors and the Hyperledger Foundation community to review and assess results. As a result, a number of enhancements were identified to address report findings.

Ultimately, the exercise concluded that Ursa provides a solid security footing for projects dependent on the Hyperledger family of technologies applicable to digital identity.

Review findings summary:

In general, the review noted a few relatively minor security defects, some implementation guidance, and some general observations for library improvement.

These can be briefly described as follows:

Minor build issues
Cautions to consider when building, primarily with third party libraries or integrations
Minor issues related to lack of support for message augmentation
Minor issues related to subgroup validation
An issue related to public key validation

Revue de code Hyperledger Ursa

Hyperledger Ursa est une librairie cryptographique partagée utilisée pour éviter la duplication du code lié à la cryptographie. La librairie est un répertoire opt-in (pour les projets Hyperledger et ceux qui ne le sont pas) pour placer et utiliser la cryptographie.

Le déploiement à grande échelle de l’identité numérique dépendra d’une forte sécurité afin de fournir les niveaux d’assurance élevés requis dans de nombreuses transactions des consommateurs avec leurs gouvernements, leurs institutions financières et d’autres organisations de confiance.

Les principales avancées en matière d’identité décentralisée, dont plusieurs proviennent du Canada, reposent sur la famille de technologies Hyperledger. En tant que tel, Hyperledger Ursa est un composant central sur lequel on compte pour fournir la couche de sécurité pour l’identité décentralisée.

Dans un esprit «de confiance et de vérification» (en anglais, trust but verify), plusieurs entités du secteur public canadien et Interac (le réseau interbancaire du Canada) ont parrainé un projet au Laboratoire d’identité numérique du Canada (IDLab) pour effectuer une revue de code de sécurité et de cryptographie d’Hyperledger Ursa (le rapport complet est disponible ici, en anglais seulement).

Les initiateurs de ce projet ont estimé qu’il était important d’avoir une évaluation indépendante par un tiers de ce composant fondamental de la famille Hyperledger pour comprendre les risques (s’il y en a) assumés avec le déploiement et l’utilisation de la technologie basée sur Hyperledger dans le domaine de l’identité décentralisée.

Aperçu de la portée de la revue de code de la librairie Hyperledger Ursa :

Une revue de code qui a examiné :
- Les points d’entrée
- Les standards de programmation
- Stockage et transfert de données
- Les interfaces API et leur sécurité
- Utilisation de librairies de tiers
- Problèmes de langage de programmation
- Défauts de logique
Les meilleures pratiques en matière de cryptographie, y compris l’examen :
- De la cryptographie et la gestion des clés
- De l’entropie
- Des meilleures pratiques en matière d’utilisation de la cryptographie

L’examen n’a pas inclus une évaluation de la fondation des algorithmes cryptographiques eux-mêmes, ni de leur aptitude. L’examen s’est limité à l’évaluation de la bonne mise en place dans Ursa.

Après l’examen du code et la documentation des résultats, l’équipe d’IDLab a travaillé en étroite collaboration avec les principaux contributeurs d’Ursa et les membres de la communauté de l’Hyperledger Foundation pour examiner et évaluer les résultats. En conséquence, un certain nombre d’améliorations ont été identifiées pour répondre aux conclusions du rapport.

Ultimement, l’exercice a conclu qu’Ursa fournit une base de sécurité solide pour les projets qui dépendent de la famille de technologies Hyperledger applicables à l’identité numérique.

Résumé des conclusions de l’examen :

En général, l’examen a relevé quelques défauts de sécurité relativement mineurs, quelques conseils de mise en place, et quelques observations générales pour l’amélioration de la librairie.

Celles-ci peuvent être brièvement décrites comme suit :

Problèmes mineurs de construction
Précautions à prendre lors de la construction, principalement avec des librairies ou des intégrations de tiers
Problèmes mineurs liés à l’absence de prise en charge de l’augmentation des messages
Problèmes mineurs liés à la validation des sous-groupes
Un problème lié à la validation des clés publiques
