Process Transformation for Public Services Driven by Blockchain

By Gopikrishnan Konnanath, Senior Vice President, Global Head – Engineering Services and Blockchain, Infosys, and Srikanth Challa, Senior Director, Blockchain, Infosys Blog, Hyperledger Aries, Hyperledger Fabric, Hyperledger Indy

Several government departments around the world are keen to offer their citizens seamless interactions and engaging experiences, akin to those in the private sector.

The public sector is often riddled with manual processes, time-consuming verifications, legacy systems leading to low transparency and high costs. Over the years, digitalization has alleviated some of the challenges, but rising threats on privacy, data security coupled with the increasing legislations that enshrine the right-to-be-forgotten such as Europe’s GDPR or California’s CCPA pose new challenges for leaders serving in the public sector.

In the future, we will witness a monumental shift in what citizens will come to expect from their governments – nothing short of how they experience retail or banking in their life. While this digital transformation has already begun in the public sector, technologies such as blockchain are essential foundations that will power the next generation of citizen experiences. Blockchain and, more broadly, distributed ledger technologies will create a core of trust, transparency, and immutability that breaks down information silos, reducing cost all while vastly enriching the citizen experiences.

Infosys is proud to have been part of the transformation that is driving change in the public sector. We are happy to share a couple of examples where Infosys brought our strong capabilities in blockchain to help clients reimagine citizen experiences.

Blockchain helps reimagine public records validation for Riverside County California

Riverside County California relied heavily on security paper and wet signatures to establish ‘trust’ and authenticate records. Citizens often had to wait for the physical copies of verified documents to reach them by post, which led to delays. In addition, easy access to numerous online tools increased the incidence of fraud, making it challenging to verify proof-of-records and physical documents, which was done manually.

Infosys Public Services helped create a blockchain-based digital records fulfillment solution for Riverside County’s Assessor-County Clerk-Recorder Office. Built on the Hyperledger Fabric blockchain framework, the new platform can seamlessly verify and authenticate several types of digital records (like land records, births, marriages, and deaths). The solution also bypasses physical paper records by issuing digital documents when a citizen or entity requests them, thereby providing an e-commerce-like experience. The blockchain solution will help Riverside County California achieve cost savings, faster turnaround time, and enhanced customer service.

Read the full case study to see how Riverside County authenticates and delivers digital records with 100% trust to citizens.

Blockchain streamlines professional license issuance and verification for the State of Rhode Island

The Department of Business Regulation (DBR) in the State of Rhode Island chose to pilot a blockchain solution for identity validation, which is a pre-requisite for issuing licenses. The department used paper-based applications to issue nearly 200,000 licenses annually. This led to high operational inefficiencies, greater costs, and a poor citizen experience.

DBR partnered with Infosys Public Services (Infosys) for its proven expertise in transforming government processes and implementing blockchain technology. Infosys implemented a blockchain-based identity and credential management solution using Hyperledger Indy and Hyperledger Aries that can quickly and securely validate an individual’s credentials. The solution is built on the Self-Sovereign Identity Model where citizens are the custodians of their data (i.e., personal data is stored on citizen mobile wallets, not on the blockchain). Instead, the blockchain stores the information needed to cryptographically validate the citizen’s credentials, which is shared with other parties. This solution can be easily adopted by other departments within the state paving the way for greater adoption across the entire state.

Read the complete case study to see why blockchain was the right solution for the State of Rhode Island.

Beyond the buzz, blockchain is proving to be a beneficial technology in the real world across banking, insurance, retail and other industries. Governments around the world are not sitting on the sidelines but jumping mainstream into this disruptive technology to drive citizen-centered governance.

To learn more about how Infosys leverages blockchain technologies to build reliable, trusted and sustainable ecosystems for governments and other organizations, go here.

#HyperledgerIdentity round-up: A cross section of production digital identity solutions built using Hyperledger technologies

By Hyperledger Blog, Hyperledger Aries, Hyperledger Fabric, Hyperledger Indy, Hyperledger Ursa, Identity

Verifying identities and information in a digital world is critical for establishing trust. But there are issues of privacy as well as efficiency, scale and accuracy in models that rely on centralized data collectors and databases.

The adoption of a new generation of digital identity solutions that leverage decentralized technologies such as distributed ledgers and verifiable credentials is accelerating. And Hyperledger technologies are playing a major role in this transformation.

Read on for a cross section of the many Hyperledger-powered solutions that are in production now. For other examples, check out these past #HyperledgerIdentity round-ups:

IBM Digital Health Pass

IBM Digital Health Pass, built on Hyperledger Fabric, offers a multi-credential verifier that organizations can use to manage and execute their verification policies for COVID-19 and vaccination status in a way that balances the privacy of the individual with the requirements set by the organization and local health authorities. With IBM Digital Health Pass, organizations can verify multiple types of health credentials, such as Good Health Pass, IBM Digital Health Pass, Smart Health Card and EU Digital COVID Certificate. Privacy is central to the solution, where the verifier application minimizes the personal data that is ever displayed to the user through the execution of business rules and it never lets any personal data leave, or be stored in, the verifier app.

Indicio Network

The Indicio Network is a collection of four professionally-staffed, enterprise-grade public-permissioned ledgers that provide a neutral, independent, and reliable network for the exchange of verifiable credentials. MainNet, DemoNet, TestNet, and TempNet are all Hyperledger Indy-based networks with nodes operating on five continents—and a growing number of node operators. The Indicio Network is one of the networks that can support Indicio Proven, a complete suite of decentralized identity components for authenticating and sharing high value data in a privacy-preserving way using verifiable digital credentials. Built on Hyperledger Aries and Hyperledger Ursa, as well as AnonCreds and DIDComm, Proven is designed to make implementing and using these open source codebases simple, providing users with a fully-owned solution that’s easy to integrate with existing systems, to innovate on, and to scale.

IDUnion

IDUnion, the European identity verification network created as part of the “Secure Digital Identities Showcase” funding project, brings together public institutions, government agencies, private organizations, associations, educational institutions and other stakeholders from various fields to enable a fundamentally new, secure digital infrastructure for the verification of identity information. In August, 2022, IDUnion spun off Sociedad Cooperativa Europea (SCE) to operate the production network for credential verification.

The IDUnion network, which is built on Hyperledger Indy, enables the clear verification of individuals, companies and institutions while allowing people and organizations to manage their identity information by themselves and to decide when they want to share this information and with whom. It has a decentralized structure and stores no personal data – not even as a hash. In order to protect privacy right from the start, all personal data is stored on the user’s end device. Users have a choice of wallets for storing and presenting credentials to third parties as required. Credentials are issued, verified and stored using open standards to ensure interoperability. Hyperledger Aries is the framework for managing the credentials.

NHS Covid-19 Digital Staff Passport

In 2019, the NHS was preparing to pilot a digital passport project that would allow staff to carry their HR and other records as credentials on their phones as a long-term plan to make it easier to transfer from one facility to another. When the pandemic hit, this went from a pilot to a production deployment quickly. The NHS Covid-19 Digital Staff Passport rolled out in summer to support swift and efficient staff movement between NHS organizations in response to the response health emergency. The COVID-19 Digital Staff Passport provided a solid legal framework for staff to be temporarily deployed into other NHS organizations with evidence available that checks have been completed before staff move. As laid out in the pilot, the information was transferred securely by the staff member as verified credentials stored on their own smartphone, putting them in control.

This staff passport used the Sorvin Network, which is built on Hyperledger Indy, to verify the digital credentials, and the Evernym (now Avast) Connect.me digital wallet app, which is powered by Hyperledger Aries, Indy and Ursa, to enable staff to store and share their credentials.

The NHS is now gearing up to roll out the next generation of its Digital Staff Passport, which will streamline transfers and staff movements through the NHS.

OrgBook BC

OrgBook BC is a searchable public directory of organizations registered in British Columbia, Canada, provided by the BC Government’s Ministry of Citizens’ Services. OrgBook BC provides verified data, including legal names and DBA names, business numbers, BC registration status and select licensee and permits, for more than 1.4 million organizations. All of the information in the OrgBookBC is received, stored, verified and displayed using the latest digital trust technologies.

OrgBookBC uses verifiable credentials to ensure that information about organizations are digitally signed by the entity that issues it. Issuers are public sector organizations that hold information about businesses, issue licenses or permits or certify processes. That electronic signature stays with the data throughout its life in OrgBook and is validated before its is display on the website.

OrgBookBC is part of an overall commitment to digital trust technologies by the Government of British Columbia. In addition to deploying Hyperledger Aries, Indy and Ursa, the team there is leading much of the open source development for those projects. Read more on the Government of BC’s investment in verifiable credentials and digital wallet technologies here.

Energy & Mines Digital Trust: The Open-Source Journey Towards a Clean, Resilient Economy

By Energy & Mines Digital Trust Blog, Climate, Hyperledger Aries, Hyperledger Indy, Identity

As the world works towards climate goals, a government project from Canada is using digital trust technology to make it easier and more secure for natural resource companies to share sustainability data.

Energy & Mines Digital Trust (EMDT) was established by the Government of British Columbia in recognition that we must do more to facilitate the transition to a clean, resilient economy. British Columbia (B.C.), Canada’s western-most province, was the first province in Canada to implement greenhouse gas emission reduction targets and mandatory sustainability reporting for major sectors of the provincial economy. As leaders in climate change legislation, B.C. is well positioned to explore cutting-edge technology in the journey towards a low-carbon economy. To improve trust, accuracy, and efficiency when sharing sustainability data, EMDT is coordinating a digital ecosystem – a network of organizations including environmental auditors, government bodies, mining and energy companies, and non-government organizations.

Improved Sustainability Reporting

Currently, reporting sustainability data can be challenging. Data is difficult to exchange internationally, and consumers cannot always access, or trust, reported data, not to mention the administrative burden.

EMDT’s digital ecosystem makes it possible to exchange sustainability information simply and securely, using digital credentials.

Digital credentials:

Can be shared quickly and are tamper-proof.
Allow companies to control their data.
Guarantee the integrity of the information.
Preserve privacy in business-to-business interactions.

Digital Trust Ecosystem: EMDT Pilot

EMDT has been testing and refining their technology and governance through multiple pilot projects to demonstrate how sustainability reporting can be made more efficient and trustworthy. Two pilot projects explore greenhouse gas emissions reporting in the mining sector and the natural gas sector. These pilots allow participants to test sharing and receiving digital credentials that include verified GHG emissions data for a specific mine site or natural gas facility.

*Because this is a pilot, the process depicted in this diagram does not satisfy or replace existing regulatory reporting obligations.

The greenhouse gas (GHG) mining pilot builds upon the existing regulatory emissions reporting process in British Columbia. PricewaterhouseCoopers (PwC), an environmental auditor, issues a digital credential to Copper Mountain Mining Company containing verified GHG data. Copper Mountain can then use the Greenhouse Gas Emissions Report Verification Credential as part of their GHG emissions report to British Columbia’s Climate Action Secretariat. Copper Mountain can use the same digital credential to complete voluntary reporting to organizations such as the Open Earth Foundation.

Increased Connections

To facilitate the broad exchange of sustainability data, EMDT used Hyperledger Indy and Hyperledger Aries to create a highly interoperable tool, called Traction. Traction is an API accelerator built on top of Hyperledger Aries Cloud Agent Python (ACA-PY). Traction streamlines the process of sending and receiving digital credentials for governments and organizations.

Hyperledger Aries makes Traction highly interoperable with the technological solutions of companies and organizations around the world. “While two wallets might be different implementations or might be written in different code, they can still exchange data because both wallets use Aries,” explains Kyle Robinson, EMDT’s Senior Strategic Advisor.

Traction makes it easier to integrate digital trust technology into existing lines of business:

API-first Architecture: Traction is designed with an API-first architecture. This RESTful API allows for integration into existing line-of-business applications already being used by organizations. The Tenant user interface is built on this API to enable adoption prior to integration and for low-use functions.
Multitenancy: ACA-Py is implemented on a cloud-based server so multiple wallets can be managed with one Traction instance.
Higher Scalability: Traction is open-source technology, encouraging collaborative refinement, faster release, and higher scalability of the technology.

Collaborative Climate Change Progress

With an increasing emphasis on responsibly sourced products, simplified methods for exchanging sustainability data ensures that B.C. natural resource providers can compete in a global market. Digital trust technology streamlines access to trustworthy sustainability data, allowing businesses, governments, and non-government organizations to work towards climate change goals more efficiently and effectively.

Developer showcase series: Jason Sherman, Developer at Energy & Mines Digital Trust, Government of British Columbia

By Hyperledger Blog, Climate, 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 Jason Sherman, Developer at Energy & Mines Digital Trust, Government of British Columbia’s Ministry of Energy, Mines and Low Carbon Innovation.

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

Energy & Mines Digital Trust (EMDT) is a pilot project enabling a collaborative digital ecosystem between the B.C. government, natural resource companies, and organizations around the world, making it simpler and more secure to share sustainability data. I am currently working on EMDT’s technology, called Traction. Traction is basically a layer above Hyperledger Aries Cloud Agent Python (ACA-Py) that enables the Government of British Columbia to use our technology for line of business applications. This allows the government to onboard into the world of digital credentials easily, and to track their business data with their credential and presentation exchanges.

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

We are using Hyperledger Aries Cloud Agent Python (ACA-Py) and Hyperledger Indy. Using Hyperledger frameworks has increased Traction’s interoperability, making it possible to incorporate a broader range of participants, tools, and technologies into the digital ecosystem EMDT is coordinating. We’re using Hyperledger’s open-source software to accelerate the Government of B.C.’s ability to adopt these tools. My experience with Hyperledger technologies is that things change quickly! And any problem or use case I identify is usually already being addressed.

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

I think the Hyperledger Foundation should focus on multiple ledger support (which is already underway) and onboarding users (not developers) of the implemented technology.

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

There is a very steep learning curve, but it’s extremely worthwhile. You will very quickly identify areas where the technology could benefit your clients.

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 interested in the ability for Hyperledger projects to enable more automated business flows using truly trusted and tamper-proof data. The number of personnel hours that can be saved just through automated conversation and interchange of data programmatically is massive.

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

I am hopeful that blockchain has the potential to improve trust between businesses. By exchanging information using blockchain technology and digital credentials, the validity and origin of the credential can always be verified, and businesses can proceed with their interactions confidently.

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

I would hope to see blockchain as a viable and easily selected technology, along the lines of Postgresql or MongoDb. I would hope that blockchain could be adopted as a mainstream technology that development teams can look at as a solution to solve their problems.

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

Your code isn’t precious.

What technology could you not live without?

Plumbing.

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.

Hyperledger identity community completes development of DID:Indy Method and advances toward a network of networks

By Char Howland and Daniel Bluhm Blog, Hyperledger Indy, Identity

New Hyperledger Indy updates pave the way for verifiable credentials to be issued and read on different networks, affirming Hyperledger as the most advanced framework for interoperable, decentralized identity

Earlier this year, the Government of British Columbia announced the “Indy DID Method Code With Us” challenge. The goals were to align the content that can be written in the DIDDocs published on Hyperledger Indy networks with the current World Wide Web Consortium (W3C) Decentralized Identifier (DID) Specification and to add a namespace element to DIDs (and other object identifiers) published on Hyperledger Indy networks, so users know on which of the many Hyperledger Indy networks the DID was created.

Hyperledger Indy is an open source project housed at the Hyperledger Foundation providing the codebase to create distributed networks, purpose-built for SSI and verifiable credentials. Networks built on Indy are some of the most mature and tested networks with self-sovereign identity (SSI) capabilities; but since they were developed before the publication of the World Wide Web (W3C) DID Specification, they needed to be brought into alignment.

While the Indy DID Method began as a community development effort within Hyperledger Indy, it needed a push to completion; hence the Code With Us challenge from the government of British Columbia. Indicio was awarded the challenge and went on to develop and complete several of the remaining components.

The result is that a credential issued using any Hyperledger Indy network (such as Indicio, Sovrin, Findy, Bedrock, IdUnion, etc.) can be processed by any verifier. This is because the objects in the verifiable presentation reference the Hyperledger Indy network used by the issuer. The Indy:DID Method lays the groundwork to make this possible.

This advancement in interoperability is significant. While issuers still need to be anchored in the specific Indy ledger of their choice, holders can seamlessly receive verifiable credentials from issuers rooted in different Hyperledger Indy networks, and be able to create verifiable presentations from any combination of those credentials. Likewise, verifiers will be able to verify presentations that include claims derived from credentials rooted in multiple Indy networks. The Indy:DID Method paves the way for Hyperledger Indy credentials to scale by allowing Indy networks to seamlessly interoperate, creating a global “network of networks” effect.

With the groundwork complete, networks and agent frameworks now need to incorporate the Indy:DID Method. This community adoption will increase the viability of the Indy and Aries project stack and position it to be the globally dominant way to issue and share verifiable credentials in a multi-ledger world.

To learn more about did:indy and the next steps for implementation, you are welcome to join the leading contributors from Indicio and BCGov at the Hyperledger Identity Implementers Call taking place, Thursday, May 5, 8:00 AM US Pacific (3pm UTC)

Call for Applications: 2022 Hyperledger Mentorship Program

By Hyperledger Blog, Hyperledger Aries, Hyperledger Besu, Hyperledger Bevel, Hyperledger Cacti, Hyperledger Fabric, Hyperledger Indy, Hyperledger Mentorship Program, Hyperledger Ursa

Want to jump start a career in blockchain development? Ready to build hands-on skills developing leading-edge open source technologies? Looking to work directly with mentors who are invested in you and your work? Then the Hyperledger Mentorship Program is for you.

Now in its sixth year, the Hyperledger Mentorship Program provides a structured and guided learning opportunity for anyone, at any career stage, looking to get started in the open source movement. With full and part time options, fully remote work and a stipend, the projects are designed to be a pathway to becoming a contributor to the Hyperledger community that work for students, people in career transition and anyone else who wants to develop or sharpen their knowledge of cutting-edge blockchain technologies. Applications are now open.

This year, the Hyperledger Mentorship Program has grown to 30 planned part and full-time projects covering a range of technologies, challenges and technical difficulty levels and includes non-development projects such as Ecosystem Analysis and Developer Marketing. Each project is designed and proposed by active members of the Hyperledger community. Those who propose the projects serve as the mentors and work closely with their mentees on developing a project plan, setting milestones and solving problems. Mentees can expect regular evaluations and feedback. For more about the program, including the schedule and stipend details, go here.

Over the last five years, more than 70 mentees have completed Hyperledger Mentorship projects. Each of these mentees have made concrete contributions to Hyperledger projects and built important connections in the community. Some, like Bertrand Rioux, have gone on to become mentors themselves:

“I was accepted into the Hyperledger mentorship program last year after seeking a community to help advance my professional goals of developing software for climate action. I was fortunate to find a diverse group of mentors that helped me build the knowledge and skills I needed to effectively contribute to the Hyperledger open source community and to have the opportunity to develop technical expertise in a field I was actively working in. In addition to delivering a secure identity management solution for a Hyperledger Fabric Network, I started contributing my own ideas to the open source operating system for climate action. As a result, I am now taking a leadership role in the community. In addition to serving as mentor in this year’s program, I proposed a project on reducing waste emission in the oil & gas industry that was accepted.” – Bertrand Rioux, Independent Energy Consultant and Mentor for the Multiple Data Integration to Hyperledger Fabric Climate Accounting Network project

To learn more about the Hyperledger Mentorship experience and outcomes, check out these spotlights on last year’s projects with highlights from both the mentors and mentees.

Read on for descriptions of some of the projects planned for this year:

Multiple Data Integration to Hyperledger Fabric Climate Accounting Network

The Hyperledger Labs blockchain-carbon-accounting project includes a Hyperledger Fabric network for recording the carbon and Greenhouse Gas (GHG) emissions that cause climate change. Since there are many activities that cause such emissions, the network is designed to accept data from multiple sources of measurements. In this project, we will demonstrate integrations from measurement sources with blockchain networks by integrating the ThoughtWorks cloud computing emissions calculator, the NREL OpenPath mobile application, and other web- and mobile-based API’s sources to turn instrumented readings into emissions measurements. It will leverage previous projects involving Hyperledger Cactus, Vault security engines, and client security for Hyperledger Fabric.
