GSBN Builds Global Trade Operating Platform with Hyperledger Fabric as the Foundation

By Hyperledger Blog, Hyperledger Fabric, Supply Chain

Read the full case study here.

Global trade is systemically important to the world’s economy. In 2021, it represented $28.5 trillion. Yet, it hasn’t evolved along with the digital transformation of other industries.

Perhaps that’s because evolution seems like an insurmountable task. Processes are complex. Documents and information flow continuously — but asynchronously — between parties across the globe. Many processes still rely on paper and legacy systems.

This lack of digital, on-demand data makes it difficult for the shipping sector to respond to global events, like the COVID-19 pandemic in 2020 or the supply chain disruptions in 2021. In short, existing global trade processes aren’t efficient nor resilient enough.

GSBN, a not-for-profit backed (and governed) by a collection of major shipping lines and global terminal operators, set out to create the trusted data sharing infrastructure needed for efficient, digital and resilient global trade. To do so, GSBN built a new global trade operating platform using Hyperledger Fabric as the foundation.

The initial launch of GSBN centered around a Cargo Release offering aimed at improving shipping container turn-around time, reducing port congestion and pollution. Since its launch in March of 2021, more than 10,000 customers have used Cargo Release to get real-time updates on over 1 million shipments.

In September 2021, GSBN formed the Trade Finance Advisory Group with Bank of China (Hong Kong) Limited (BOCHK), DBS Bank and The Hongkong and Shanghai Banking Corporation Limited (HSBC) to develop digital solutions to help improve the financing process for banks. To break barriers in data sharing that were hindering financing approvals for trade companies, especially SMEs, GSBN created an application for consent collection. It allows banks to source data directly from shipping lines so they can verify information based on a single source of truth.

The third application for GSBN is electronic bills of lading (eBL). In June 2022, IQAX eBL application, built on top of GSBN, obtained approval by the International Group of P&I Clubs. The eBL application provides a digital channel for all parties to access real-time data on the shipping process. It also guarantees the security, accuracy, and authenticity of data. And it ensures the data on the blockchain network is traceable to a single source. This application has already been adopted by three shipping lines and one bank.

The Hyperledger Foundation team worked with GSBN on a case study that details the business and technical drivers and decisions that went into the creation of GSBN as well as key results to date. It also lays out how GSBN, as CTO Edmund To puts it, “will expand the global trade ecosystem by creating bridges to new market participants like banks, FinTech’s, and other consortia and launching new solutions.”

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.

#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.

#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

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.

Developer showcase series: Matthew B. White, IBM

By Hyperledger Blog, Developer Showcase, Hyperledger Fabric

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Matthew B. White, Lead Software Engineer at IBM.

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

Can’t really recall when I first heard of blockchain or indeed cryptocurrency; but it was the new thing that obviously was creating interest. My natural curiosity wanted to know more about this.

There were a couple of internal staff briefings I listened into to get some background; plus the people who were involved were ones I’d worked with previously and respected. This wasn’t some random idea that had no real benefit. As luck would have it, I saw an opening to move into a newly created team at IBM focusing on blockchain and went for it.

Since that point I’ve not looked back and have worked on a number of aspects of Hyperledger Fabric and IBM’s offerings.

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

Currently it’s as a contributor and maintainer of Hyperledger Fabric. It’s been a really enjoyable time working with open source.

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

There are two big challenges I believe. Collaboration and applicability

Blockchain requires a collaboration between ‘entities,’ companies, people, etc. A collaboration that many previously wouldn’t have thought of. For example, the many companies that form a supply chain. It’s this collaboration that is key to blockchain and needs to remain a focus as Hyperledger technologies are adopted more widely. For example, how do multiple companies adopt Hyperledger Fabric for supply chain solutions?

There are many use cases, from the token space (tracking both assets & currency) to supply chain tracking and auditing to distributed identity, where the concepts and features offered by a blockchain can help. Likewise, there are many Hyperledger projects and labs. That leads to the applicability challenge. For the outside user looking in, it can be hard to know how to apply these technologies to real solutions. For example, how does Hyperledger Grid work with Hyperledger Fabric for supply chain solutions? How do I use Hyperledger Indy to get distributed identity linked with my existing systems?

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

Like any new technology, there is the initial “it’s the best invention since the wheel” hype. The key thing to blockchain is that to make it worthwhile requires the collaboration mentioned before. That’s the hard part and the part we need to focus on.

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 one we haven’t thought of yet!

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

The lack of trust between parties.

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

As mainstream as, say, a database or a rest server.

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

You’re not writing the code for yourself; you’re writing for either your future self or more likely somebody else. Don’t add a comment saying “this next line calls an array sort function,” but add a comment “why does this array need to be sorted? What is the scale of the data and how did that affect your choice of sort algorithm? Are there controls in the system that would change the assumption about the scale of the data.”

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?

Developer showcase series: Navil Rodrigues, Coding Bootcamps

By Hyperledger Blog, Developer Showcase, Hyperledger Fabric, Hyperledger Transact

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Navil Rodrigues of Coding Bootcamps.

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

To the newbies starting out their journey in the blockchain space, I would suggest having a strong grasp on fundamentals like cryptography and data structure like merkle tree to know how blocks are linked with each other. After which I would suggest reading the book “Mastering Bitcoin by Andreas” to enhance your knowledge. Later on you can choose a public or private blockchain that interests you.

Give a bit of background on what you’re working on, and let us know what was it that made you want to get into blockchain?

I am currently working as a full-time blockchain developer at Mckinley Rice. My most of the time goes architecting and implementing smart contracts for Ethereum and sidechains. I also have experience in developing and designing ICO contracts and bridging solutions to connect different chains. The “State of trust,” “Decentralization” and “Immutable data records” made me fall for this technology.

What Hyperledger project(s) are you working on? Any new developments to share? Can you sum up your experience with Hyperledger technologies?

I have worked on a supply chain finance platform built upon Hyperledger Fabric that was developed to provide a common platform for suppliers, anchors and financial institutions. I keep an eye on what’s new in Hyperledger Fabric to stay updated with the latest developments. I would say the community behind the Hyperledger umbrella development is very active and its industry experts.

What are the main differences between developing blockchain applications in Hyperledger Fabric or Ethereum?

There are several differences. For instance, the consensus algorithm or architecture of a popular public blockchain like Ethereum or Polygon is very different from Hyperledger Fabric as they serve different purposes. Likewise, when it comes to NFT assets on a public network like Polygon versus a private network like Hyperledger Fabric, public networks allow integration with cross-chain networks and DeFi. For example, RealBig NFT assets are tied into both crypto exchanges and DeFi platforms for staking.

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

The most important thing Hyperledger can focus on is increasing the number of transactions per second. Also, we like to see Hyperledger tools and libraries that are currently at incubation stage become active.

As Hyperledger’s incubated projects start maturing and hit 1.0s and beyond, what are the most interesting technologies, apps, or use cases coming out as a result from your perspective?

Hyperledger Transact is a really interesting product. We need methods for quickly creating distributed ledger technology (DLT) applications.

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

Blockchain is going to solve many problems. However, I am looking forward to seeing blockchain being adopted and implemented more by private companies.

Where do you hope to see Hyperledger technologies and/or blockchain in 5 years?

We hope to see robust widely accepted Hyperledger DLT applications especially among enterprise companies.

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

Spend more time on architecting a solution thoroughly than developing it.

What technology could you not live without?

The Internet.

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.
