Removing Barriers to Contribution with Regional Community Chapters

By Blog, Regional Chapter

In a global community it is important to recognize that different people in different areas face different barriers. Perhaps the barriers to entry for English speakers in Silicon Valley with fast internet connections are very low, but what is the contribution experience for others?

Successful open source communities make sure that the barriers to entry and contribution are low. Even if your community has done work to make it easy to contribute and if many people have already gotten involved, there could still be many significant barriers that you don’t know about.  

It can come as a surprise to find out that potential community members may think that your project is not inclusive and is a place where they are not welcome. Identifying and dealing with barriers on a regional level will help create a diverse community that includes contributors from around the globe.

Empowering and supporting people developing local, community-led efforts is the best path to addressing the needs of each region. Hyperledger community members have recently been forming regional chapters that bring together people of a common language, culture or geography to collaborate on activities that are relevant for people in those areas.

In just two years, we have launched the India, Brazil, Latinoamerica, Africa and Italian regional chapters.  This post shares details about how these local chapters have dealt with some of the barriers to contribution that people in different parts of the world face. The structure of these chapters owes a lot to the regional community building that other open source projects, like Mozilla, have done. 

Language barriers

Most people in the world don’t speak English, but most of the meetings, discussions, events and other Hyperledger community activities are conducted in English. This isn’t a barrier for English speakers, but it is a huge barrier for people who speak other languages.

The regional chapters have started to address this by creating material and having discussions in a range of different languages. Hyperledger’s 2020 Annual Report has a nice visualization of the community activities that happened in multiple languages last year, including meetups, training, documentation and more.

Cultural barriers

Hyperledger has created a Code of Conduct to establish what sort of behavior is acceptable and unacceptable in the community. However, there are times when people show up and violate those guidelines, and that is a barrier for people who experience that behavior.  

As virtual meetings became the norm during the pandemic, so did the unfortunate by-product of “zoombombing.” This refers to the unwanted, disruptive intrusion, generally by Internet trolls, into a video-conference call. Unfortunately, we live in a world where some people do not respect people from other cultures, and we have had this happen to some community members.

Last year, members of the Hyperledger community in Africa ran a virtual meetup, and it was disrupted by people who dialed in to harass those who were trying to participate. Verbal abuse and inappropriate comments in the chat transpired, and the event had to be stopped. That meetup was rescheduled, and it went well. However, in the next meetup the same community in Africa organized, there were again people who dialed in and disrupted the event.

Those incidents drained a lot of momentum and enthusiasm from the community members who were organizing those events. In response, we changed how we configured the Zoom accounts used for community calls to filter out people seeking to disrupt events. With these safeguards now in place, the community in Africa is making plans to resume events in 2021. It is vital for Hyperledger to create an environment where these community members can contribute successfully if we are going to be a truly inclusive open source project.

Time zones and technical barriers

Whenever a community discussion happens in real time, whether on a call, at an event or in a chat channel, there will be people who have difficulty participating because of time zones. It is not unusual to be on a call where someone is joining in at midnight their time. There is no time of the day when everyone is awake and working, so this is a big challenge for open source communities. Real-time activities aren’t evenly distributed though, and a bulk of Hyperledger community meetings happen at a time that works well for people in Europe and the Americas.

The India Chapter has addressed the  time zone issue  by creating a wide range of meetings and events that happen at times that work well for the local community. Running these events and also having some community members participate in the global community activities provides an easier way for people in India to contribute and also maintain a bridge to the rest of the community.

Sometimes people can’t join in community discussions or activities at all because access to tools is restricted. Some countries, such as China, as well as some large companies block access to tools that are frequently used by community members, such as Zoom and Google Docs. And there are countries where the Internet infrastructure is not robust and stable, making it a challenge to join a live video call. In these cases, people in a region need to find alternate tools that can be accessed and then find ways to be a bridge to connect local activities with the rest of the community.

Get Involved

The Regional Chapters have become a great way for community members to connect, especially during the pandemic since we haven’t been running local in-person meetups.  Increasing collaboration among areas in different regions has brought about greater participation and diversity to Hyperledger’s community.

Removing barriers to participation and expanding inclusion will always be a work in progress. There may be other barriers to entry in other regions that we haven’t identified yet as well as other examples of success stories. We welcome any feedback, suggestions, and lessons learned you have about how to make our community more diverse and inclusive for community members across the globe.  A great place to share your thoughts on this is the Diversity Civility and Inclusion Working Group’s mailing list.  Please feel free to subscribe to that list, introduce yourself and let us know what you think.

Introducing “Hyperledger In-depth: An hour with…”

By Blog, Hyperledger Fabric, Hyperledger Labs

2020 was the Virtual Year (although many of us would prefer if 2020 virtually never happened). So last March, as the world transitioned to its new virtual state, we launched our webinar series. In the 10 months since, we’ve learned quite a lot. 

First, there is amazing content out there that is worth sharing. Our members gave some great talks, and the attendance was incredible. We were really able to make up for the lack of in-person conferences. Second, it didn’t take long for us all to get tired of being on Zoom. There are only so many waking hours in the day and, for many, 70% of those are  spent on virtual meetings, many of which, let’s be honest, do not require our participation. 

How do we get out of this seemingly impossible situation and help our community connect online in a meaningful way? We are introducing a new concept: “Hyperledger In-depth: An hour with… .” In this series, Hyperledger members share learnings from their projects and try to answer all the hard questions about the pains of working with DLTs. It is not yet another webinar: participants will be encouraged to take part, come with prepared questions and voice opinions. Expect live demos and tutorials, stories from the battle field and hopefully some heated discussions. Let’s get out of the Zoom fatigue and engage to share experiences and build a stronger community.

This is exciting! We do think that with more active, engaging conversations, you will find the meetings really useful. We hope you can help us by recommending the program to your friends and colleagues – the more people, the more opinions and the better the discussions! But that’s not all. We are also bringing some more international, non-American centric vibe.

Starting January 20, we will hold webinars in two time zones so that, if you are in APAC, you will still get a chance to participate live and join the discussion. Of course, as always, all sessions will be recorded and available in our VOD library. Finally, we will now be also providing non-English content. We want to celebrate the diverse and vibrant community we have. Some of our most active members are in South Africa, India and Russia We do not want to exclude anyone! It is the host that will decide what language they will be running the session in, and we will work hard to get the slides and summary of the session in English for all of us non-polyglots. 

On January 20, come join us for the first session of the year, which will be devoted to discussing Scaling DLTs with the Perun Framework, led by Bosch. On January 27, ConsenSys will host part one of a mini-series on collaboration between the Ethereum and Hyperledger communities. The session, What is Ethereum for the Hyperledger community?, will be an AMA and a design thinking session. 

The Hyperledger In-depth calendar will be very busy as we will continue to have two events a month. Every first Wednesday of the month you can tune in at 7pm UK/2pm EST/11am PST. On the third Wednesday of every month, join us at 10am UK/7pm Japan time. Below is a sneak preview of the plan for Q1 (it might change as we are still confirming hosts):

Hyperledger India Chapter in 2020

By Blog, Regional Chapter

LinkedIn | Email | Subscribe | Rocket.Chat

Blockchain technology adoption and the startup ecosystem around it within the Indian subcontinent reached new heights in the year 2020. The Government of India announced a blockchain center of excellence where the technology is being evaluated for adoption across multitude of areas. The Hyperledger regional chapter was inaugurated in early 2019 to bolster blockchain technology in India and rapidly spread its wings in 2020.

Below are a few of the chapter’s accomplishments in the year 2020:

  • HyperHack 2020: The first ever blockchain-run, blockchain-based hackathon to attract teams from across the Asia Pacific region. Prizes worth $10,000 USD were distributed through sponsors.
  • Blockchain Stories 2020: A platform for sharing stories and learning from each other. The event, which drew speakers from over 25 organizations across the Asia Pacific, was spread across five  weeks and had over 1,000 participants.
  • Women in Blockchain: A panel discussion organized in association with the Saintgits College of Engineering with distinguished speakers from the India diaspora. The event also featured renowned names in blockchain technology.
  • Blockchain Hype to Reality: An event aimed at answering the startup ecosystem that echoed the mantra of Vocal for Local. It attracted a crowd of over 1,500 from across the Asia Pacific region.
  • Blockchain Techfest 2020: An opportunity for technology enthusiasts to meet, greet and learn from the maintainers of different Hyperledger projects. The event, held in three sessions across three weeks, covered nine Hyperledger projects..

The year also saw improvement in the way community meetings are run. The chapter adopted a more structured format for running meetings and making decisions as well as an option to hear from everybody in the community, which led to increased participation. LinkedIn engagement also increased with more than 2,300 enthusiasts showing interest in the chapter’s activities in the last year. The chapter has also produced over 25 videos on the Hyperledger YouTube channel.

Members of the India community also have taken on an increasing number of leadership roles with Hypereldger at the global level. We have chapter members actively involved in the Hyperledger technical steering committee, as maintainers and contributors across all the projects within the Hyperledger greenhouse and as noticeable contributors in special interest groups and working group activities.

The community activities have accelerated in the region. One example of the quick pace of activity: The idea of student outreach led to an immediate invite from the IEEE Computer Society Kerala Chapter. While we are still defining quarterly goals for the year 2021, here is the gist of what to expect in the coming year:

  1. Additional student outreach and the possibility of a Hyperledger India Chapter – Student Wing.
  2. Industry outreach aimed at bridging the booming startup ecosystem with the industry experts.
  3. Aligning the blockchain activities with the broader effort to make India an innovation hub.
  4. A second edition of HyperHack, a hackathon with problem statements that are more relevant to the region. Plans include special consideration for student submissions to encourage the participation. There will also be a lineup of learning activities priori.
  5. A 2021 edition of our most popular event, Blockchain Stories, with the aim of increased participation and a new wave of success stories to be shared.

Here is the statement of gratitude from the co-leads of the Hyperledger India Chapter. Arun S M is a senior software engineer at Walmart and also a technical steering committee member at Hyperledger. Kamesh Nagware is a VP Blockchain Technology at Snapper Future Tech as well as an active contributor to the Climate Action & Accounting and Trade Finance SIGs at Hyperledger.

“It is amazing to see how a vibrant and diverse set of people come together for a cause, in this case blockchain technology and Hyperledger. India is a diverse country, and its strength lies in its diversity. We at the Hyperledger India Chapter brought together the finest like-minded people from across the country under one roof.

From running the community meetings once a week as a forum for answering technical questions to having  the weekly trackable activities, it was a long journey. The community stood by us through this transformational path. We did multiple experiments with our activities through the year. At the end, we are happy for what has come out of it.

When it was the time to organize events, we were quick to identify that going virtual is inevitable. Also, the geographical location advantage India provides has made it easy for us to connect with the audiences across Asia Pacific, Middle East Asia and Europe. The continued engagement of volunteers and the  interest shown by the blockchain enthusiasts has propelled us to do even more. This feeling of ours echoed through the feedback, emails, YouTube viewership and the number of times these events were spoken about across the globe.

Hyperledger India Chapter carried the strong bond it built across Asia Pacific region, and it shows up in the continued engagement we have with the enthusiasts outside Indian territory.

On Dec 17th, 2020, Hyperledger marked five  years since its inception. On Dec 18th, Hyperledger hosted an open networking event for the Asia Pacific region as part of its 5th anniversary celebration. The event attracted an overwhelming crowd from across India.

We couldn’t be more proud of what the Hyperledger India Chapter accomplished in the year 2020. It is all possible because of the ever increasing enthusiasm we see in the community. All roads now lead to 2021. We are excited to have more community engagement in the coming year!

 We look forward to having more technical contributions from the region in 2021 and  call on all of you residing in Indian subcontinent to join our weekly calls. Let us build a better future holding hands together.

All of this would not be possible without the help of staff at the Hyperledger. Everybody at Hyperledger has stood by us. Dorothy Cheng and David Boswell specifically have eased most of our jobs.”

“Since the launch of the Hyperledger India Chapter in early 2019, it has been a pleasure for me to work with this inspiring group of volunteers, dedicated to supporting Hyperledger technologies, open source collaboration, sharing information and assisting the India blockchain community. 2020 has been a challenging year. It has been heartening to see the innovative ways the India Chapter has found to share information and support the blockchain community – in India, across Asia Pacific and globally.

In 2020 the India Chapter created and ran engaging events online – from it’s HyperHack hackathon, to the informative Blockchain Stories series, to it’s Women in Blockchain event and much more. It set up exciting programmes in areas such as student outreach and tirelessly worked to meet, communicate with and support the community.

The India Chapter was the first of its kind in the Hyperledger community, and it has inspired the creation of Chapters around the world.

The India Chapter has grown immensely and accelerated its development in 2020. I am excited to see how they build on their successes as we move into 2021 and face the challenges and opportunities ahead. I know they will bring energy, commitment and inspiration to all that they do.

There are so many in the Hyperledger India Chapter who deserve recognition and thanks from the Hyperledger community. I would particularly like to thank Arun S M and Kamlesh Nagware for their great leadership in 2020.

I look forward to working with the Hyperledger India Chapter in 2021.”

From all of us at the Hyperledger India Chapter, we wish you all a very Happy New Year!

In this series of blog posts, you will hear from many of our active volunteers on what the year 2020 and the Hyperledger India Chapter brought to them.

Blockchain technology for healthcare data management

By Blog, Healthcare, Hyperledger Fabric

The accelerating digitization of the healthcare sector has led to the creation of large volumes of sensitive data stored online. Swiss eHealth strategy promotes the adoption of the electronic patient record to allow registered patients and authorized healthcare professionals to access medical data anytime and anywhere. To achieve this, a reliable, compliant, and privacy-preserving solution is required to support definition, maintenance, and enforcement of fine-grained authorizations (consents). Convergence of distributed ledger technology and intelligent data management approaches provides a unique opportunity to bring trust, transparency, auditability, and optimization of medical data management and other healthcare processes. 

Recent research works and numerous PoC implementations actively demonstrate the value of blockchain technology for connecting health care stakeholders in order to help maintain a complete history of patient’s health care data, ensure traceability of the data exchange and automate claims and reimbursement processing. Transparent and auditable prescription monitoring may help to avoid incompatibility of the prescribed medications and can provide incentives for writing fewer prescriptions for certain medications such as opioids. In the pharmaceutical supply chain, blockchain can bring traceability to the tracking of pharmaceutical goods, from verification of the producer, to the transportation and storage conditions and control over drugs returned to the pharmaceutical company. Applying blockchain technology in biomedical research may facilitate new ways for patients to contribute with their healthcare data while ensuring privacy and security and  may  speed-up participant recruitment and collection of large and integrated heterogeneous data. When building such heterogeneous datasets, ensuring authenticity of the data and their sources is essential in order to make informed unbiased decisions and get valuable insights from the data. 

What are the important aspects and potential hurdles that deserve attention from practitioners when employing blockchain in the healthcare settings? While domain-specific requirements to the system functionality vary depending on the application, desirable properties of a resilient healthcare infrastructure for management of the sensitive data distributed among multiple sources are: data and process interoperability, privacy, security, and compliance. For instance, in the case of connecting healthcare stakeholders to facilitate management of patients’ history, some of the most important requirements are ensuring patients’ rights to access and share their sensitive data but also to erase their personal data. To achieve these, the system must ensure interoperability (i.e., must have the ability to exchange and interpret the data) and must be privacy-preserving (i.e, the patients must be able to have full control over the sharing/access revocation/erasure of their data). 

Data erasure (i.e., the possibility to erase the data) itself is not an “out-of-the box property” of the blockchain technology. It is challenging to comply with the right of data erasure when using immutable ledger. However, different approaches exist to address this issue including off-chain management of sensitive data, privacy-preserving techniques (such as encryption, zero-knowledge proofs (ZKP), secure multi-party computations (MPC), and data pseudonymization and anonymization. If anonymized data are released, a reliable infrastructure is required to support a trustworthy collaborative environment and to verify that the data were not altered. 

The choice of the appropriate approach depends on the underlying blockchain technology, the number of participants in the network and the sensitivity and volume of the data, among others. Moreover, patient control over his identifiable data and his actions (for instance, providing consent or authorizations) has to be efficiently verifiable and compatible with access to the data in an emergency situation such as when the patient is unconscious.

Hyperledger Fabric is a permissioned blockchain technology framework that has been actively employed in the implementations of blockchain-based systems for healthcare data management. To ensure privacy of data subjects, Fabric mainly relies (i) on multiple channels support, which make it possible to limit the access to the data to certain participants of the consortia, and (ii) on private collections where sensitive data can be exchanged peer-to-peer and stored in the private databases, yet accessible from chaincode on authorized peers and hashed to verify authenticity. Storing only hash on-chain is also used to provide verifiability of vast amounts of anonymized data for data-driven research and applications. In this case, contrary to limiting the access to the data, it is of a high importance to set up a reliable multi-cloud environment and collaborative framework – a step forward towards attaining interoperability. 

Blockchain infrastructure offered by Swisscom provides support for multi-cloud environments. Multiple non-endorsing peers provided by Swisscom are now dedicated to support verifiability of public COVID-19 related data, as a part of the multi-party, multi-source verifiable data sharing platform MiPasa. To address the scale of the problem, the types of data, languages, time-zones and jurisdictions,- many vendors joined forces to strengthen and support this blockchain-based shared infrastructure to unlock the potential of the data and deliver integrated, trusted, and verifiable insights across multiple industries around the globe.

Hyperledger Italian Chapter Launches to Bolster Local Community and Development

By Blog, Regional Chapter

The living society has long been inching toward a moment of overlap between physical and digital iterations in the so-called digital transformation of social interaction between people and legal entities.

Step by step, we are entering into a digitized society able to operate through the exchange of fungible and digitized assets.

Within this scenario, distributed ledger technologies (DLTs) have an essential role and a possible large-scale application that can be extended to various economic and social sectors by managing huge amounts of data with tangible consequences on the real life of end users. Nations are trying to onboard DLT software solutions with the intent to support development of the digital society and economy. 

In the case of Italy, the  diversified import-export-oriented economy offers a conducive environment for the development, test and adoption of blockchain solutions in a variety of sectors. This peculiarity of the Italian business structure opens several opportunities, as international trade is one of the most interesting areas of development of solutions based on DLT. 

Italian industrial sector that is worldwide famous for “Made in Italy” style carries an important market value that can strongly benefit from the features of transparency, security and traceability offered by blockchain. SMEs represent the core of the Italian industrial clusters (e.g., textiles, furniture, white goods and footwear) in addition to other important export sectors like mechanics and agri-food. Blockchain systems are inherently strong in ensuring optimal management of data provided by traditional quality assurance providers on provenance and quality of products, which could add significant value to production processes embedding this technology.

Innovative Italian SMEs are testing DLT solutions to serve these sectors, and some are starting to commercialize them. State-participated companies, financial institutions, associations and large Italian tech players are experimenting on distributed registries, for example SIA by SIAChain.

The idea of ​​proposing an “Italian Chapter” lay precisely on the purpose of ​​providing a different and more comprehensive perspective of the DLT phenomenon, being aware of the wide field of application of the technology. The Italian society should be preparing to experience a wide adoption of distributed ledger technology and the Linux Foundation’s Hyperledger in its form of independent open source software collaborative has a key role to guide the interoperability of software solutions on the market and the harmonization of institutional compliance processes between digital iterations and real iterations at national institutional level.

The main task of the chapter will be the development of the Hyperledger community in Italy and guidance for the various private and public projects born in the national territory that aim to establish a common national best practice. The Hyperledger Italian Chapter will also seek to interface with national institutional entities to provide technological support for the harmonization and creation of common technical and operational standards for national strategic projects.

In this perspective, the chapter will engage with different functional areas from the technical sector. This entails coordinating meetups, involving academic-university research projects, encouraging  private business projects in different product areas in the territory national (from finance, manufacturing industry, agri-food, luxury industry, etc.) to share knowledge and experiences, and supporting of corporate or institutional initiatives for the development of national strategic projects.

Obviously, no project can work alone, which is why we consider it essential to share this proposal with the technical, private-corporate, academic, and public-institutional ecosystem so that a community can emerge and bring together the best technology experts to face the challenges that an intensely digitized society has to deal with.

The chapter’s initial activities will include diving into some new features released like Hyperledger Cactus, a new tool by Accenture allowing interoperability between DLT networks and now within Hyperledger Greenhouse, and other amazing updates by Linux Foundation and Hyperledger members like IBM, Chainstack and Digital Asset.

We hope you can join our community!

Introducing the Social Impact Ecosystem blog series from Hyperledger’s Social Impact Special Interest Group

By Blog, Special Interest Group

The Hyperledger Social Impact SIG (SI-SIG) is a global community focused on how blockchain technology can be leveraged for a greater social impact. We are working together to identify use cases and opportunities, share feedback and lessons learned, and ensure blockchain is implemented where relevant and in a way that maximizes positive impact. 

Our SIG has put together several helpful resources to help new members find their way around. Our landing page gives a general overview of who we are and what we do. Those new to the SIG can visit the New Member Center to learn what we do and how they can participate. The Social Impact SIG Resource Center provides information on where to find resources for different sectors of the community, such as Financial Empowerment or Governance and Democracy. Our Community Presentations page is where you can find the latest discussion topics and presentations for our upcoming meetings as well as recordings and notes from past meetings. 

Since July 23, 2019, our meetings have been recorded and archived with the meeting notes, which makes them an excellent learning resource for new members and researchers alike. Highlights include talks by

If you would like to speak at a future SIG meeting, please reach out to us at the email list below.

We are excited to announce the launch of our blog post series “Social Impact Ecosystem,” which will feature blog posts from community members, guest writers and beyond on the various ways in which blockchain can be leveraged for social impact. The series will give members a chance to share what they are working on with others who are interested in our focus, and readers will be able to learn about different ways blockchain is being used to create positive changes in our world. Here is a quick glimpse of the blog posts that are in queue:

Shawn Wilborne will author a four-part series aimed at tackling the issues plaguing human consumption. From the food we eat to the clothing we purchase, we must maximize the value from every product and extend its lifecycle beyond single use. First, we’ll look at how blockchain can provide recycling and composting rewards to the masses to drive consumer adoption. Next, we’ll analyze hazardous and toxic materials to track them from the point of purchase through their proper disposal. This is vital to keeping our air, water, and soil free from contaminants that cause chronic diseases and shorten life spans. Then we’ll look at how the government can expedite the adoption of recycling and composting programs and use blockchain to verify accuracy, traceability, and program participation. Lastly, we’ll analyze how businesses and facilities can go Zero Waste and use blockchain to verify their entire supply chain. Cutting carbon not only benefits the environment and human health, but also increases brand recognition. We hope to inspire blockchain applications to preserve precious natural resources for future generations. 

Bobbi Muscara will share a series on how to develop a blockchain project to benefit your community. This will feature a series of guided checkpoints to help you identify the current needs of your community and how blockchain could be used to help.  

I will write a series addressing the varied ways blockchain is being leveraged in agriculture. While most readers will be familiar with the idea of using blockchain to track food along the supply chain to reduce food fraud and foodborne illness, there are a wide range of initiatives around the world that are focused on human rights and reducing human trafficking in our food and agriculture supply chains, environmental impact, and helping smallholder farmers and other producers access capital.

Would you like to add your project to our series? Would you like to present at a future meeting? Please reach out to social-impact-sig@lists.hyperledger.org to contribute.

Blockchain for the greater good: a round-up of #HyperledgerSocialImpact solutions

By Blog, Hyperledger Fabric, Hyperledger Sawtooth

While blockchain is taking an increasingly strategic role across a number of industries, one of its biggest areas of impact is powering applications that address the greater social good. Blockchain-based solutions are bringing new scope and scale to social impact efforts around the world. 

Read on for details about a sampling of #HyperledgerSocialImpact solutions where Hyperledger platforms are unpinning innovative new approaches to solving very hard and human problems: 

Fair Fashion

The Brazilian textile industry represents 10% of the nation’s industrial GDP, and it is also the second-largest employer in the country. Despite its importance, fashion is ranked second as the industry with most cases of forced labor or conditions similar to slavery.

As an effort to fight this problem, in recent years, brands and manufacturers in the textile industry have been auditing production sites. Because of the lack of integration between the actors of this production chain, auditings is still very inefficient, as it involves high costs and offers a vast scope of error.

To solve these problems and reverse this scenario, Blockforce – a Brazilian blockchain researcher and builder and general member of Hyperledger –  in partnership with C&A Foundation, Instituto E and COPPEAD-UFRJ, developed a blockchain-based solution called Fair Fashion. Designed using the Hyperledger Fabric framework, this solution promotes visibility and accountability in the fashion supply chain, with the goal of improving working conditions and the efficiency of processes in the production chain. 

QMC HealthID

Quantum Materials Corp (QMC) in San Marcos, Texas, has created a mobile app called QMC HealthID, which is seeking to enable people to return to the workforce by providing Covid-19 test credentials without compromising their personal privacy data protection rights. This is achieved by partnering with verified test partners who store the user’s diagnosis in QMC’s HIPAA compliant database. From a compliance perspective, QMC HealthID records all its interactions on a blockchain, providing regulators with an immutable audit trail. QMC is leveraging Hyperledger Sawtooth, which is deployed and managed by Sextant, the blockchain management platform provided by Blockchain Technology Partners (BTP), a Hyperledger member.

Silver Lining Initiative

Over 100 million people around the world will go to sleep tonight without a roof over their heads. Fortunately, technology companies are in the middle of a full-fledged technological revolution that is changing the way we deliver healthcare and social services. A prime example: the Silver Linings Initiative, the world’s first blockchain-based digital identity and marketplace solution designed specifically to empower and connect those experiencing homelessness. Envisioned by Troon Technologies, the Silver Linings Initiative aims to combat two of the biggest challenges experienced by the homeless population:

1.     Identity verification and acquisition of government identification;

2.     Access to, and awareness of, social support services.

This is managed through a proprietary software application that combines a user-friendly UX with the power of the blockchain to create a safe, secure, and trustworthy system of social support.

Trusted Voices

The exponential growth of fake content and disinformation represents a major trust gap, and points out inherent design issues in the architecture of the Internet that need to be addressed if we wish to safeguard trust and the legitimacy of information resources. Penta Network, which focuses on using distributed ledgers for data related problems in multi-stakeholder ecosystems, is tackling this challenge with Trusted Voices. 

Trusted Voices is based on Hyperledger Fabric and other blockchain technologies to provision a chain of custody for information and media assets. Trusted Voices makes it possible to demonstrate the authentication of digital content at time of original publication and subsequently track it across digital platforms, including social media. A robust chain of custody enables consumers to track content and trace information assets back to their authors and origins. Content traceability offers a powerful tool to combat the proliferation of inaccurate or unauthorized content, while concurrently protecting the intellectual property rights of the authors. There are broad opportunities for this technology: from flagging and removing fake news and disinformation to collaborative networks based on shared content.

Hyperledger Fabric at the heart of a telecommunication carrier ecosystem

By Blog, Hyperledger Fabric, Telecom

Telecommunications are a central aspect of our daily life: we are always connected through our phones as are the majority of people on the planet. To support our connectivity, communication service providers have been building a network of infrastructure and business relationships for the past few decades. The new trends of the industry (global mobile, Internet of Thing and 5G) are bringing new challenges and a new business approach. Recent projects within the industry show that blockchain is a technology that can support the industry transformation.

A common scenario

In 2018, 93 million* Americans traveled abroad, according to the U.S. Commerce Department’s National Travel and Tourism Office. Of course, all of them had a cellphone. When they landed on foreign soil, their phones connected to a foreign network. Their American carriers charged them for every phone call, text or data consumed abroad through the foreign network. In the back end, the foreign network providers charged the American ones for letting the subscribers using the local infrastructure. 

Now imagine this scenario repeating itself for the millions of people traveling every day across any country in the world or for the millions that make international calls from their home or offices to other countries. You can get an idea of how much data carriers need to manage to successfully charge each other for these services.

Every month billions of transactions need to be tracked, validated, reconciled, cleared and settled based complex international agreements between competing parties. That makes for an ideal scenario where blockchain can streamline operations and lift carriers from the burden of manual processes, legal disputes and unforeseen costs.

A growing interest in blockchain

Several telecom industry organizations, such as the GSMA and ITW GLF-backed Communication Blockchain Network, are showing interest in blockchain as the solution of choice for the management of high-volume transactions.

The main reason for this choice is that, to solve an industry-wide problem, they are looking for an industry-wide solution. A blockchain network, through its distributed ledger technology, can provide the reach and the governance required to push shared standards among competitors in the same sector in a collaborative way.

In addition, blockchain enables an open and interoperable ecosystem based on shared standards, where each player is able to bring their own data, safely share it and contribute to the achievement of their business goals.

Looking closer to the specific process of clearing and settling large amounts of transactions, blockchain has capabilities that match perfectly with the issues faced by carriers.

Distributed ledger technology allows parties to see the same data (values, volumes, etc.) for each transaction. Smart contracts translate complex agreement into digital code, so that they do not need to be manually executed any longer. Consensus mechanisms reduce the disputes at the end of the settlement process. 

These capabilities allow telecommunication companies to save time and labor dedicated to manual processes and to reduce the cash tied up in disputes.

Hyperledger Fabric  is a central enabler of such use cases. In fact, Fabric is designed to support enterprise implementation, providing scalability, security and operational tools that make enterprise transactions safe and scalable.

But there is more

The telecommunication industry is facing one of the greatest shifts in its history due the arrival of Internet of Things (IoT)and 5G. Both technologies are supporting the voice to data substitution. Historically, voice was the driver of large volumes of transactions, but now data have a larger and growing share thanks to the role of machines in generating large amounts of IoT input.

The abundance and growth of data poses carriers with the challenge of storing, managing, and exchanging that information in order to drive business value. Hyperledger Fabric can be the enabling platform of high value and innovative use cases such as data access control (empowering final users to decide how and who should have access to the data they generate), device identity (integrating blockchain, IoT and security to record device on the network and prevent harmful usage) or data exchange (create marketplaces of accessible data where data supplier are rewarded by data consumer).

To conclude, the industry is strengthening its global ecosystem and is looking for a technology that fosters collaboration and creativity. Hyperledger Fabric is an ideal fit and can allow greater efficiencies and new capabilities that have not been explored yet.
