Keynote Q+A: A conversation with Hyperledger Global Forum headliner Don Tapscott of the Blockchain Research Institute

By Blog, Hyperledger Global Forum

Oliver Johnston-Watt caught up with Don Tapscott, Blockchain Revolution author and Blockchain Research Institute co-founder, ahead of Hyperledger Global Forum, where Don will present a keynote talk. Read on to learn more about Don’s extensive history chronicling digital technology and some of the views he will bring to the stage in Phoenix:  

Oliver Johnston-Watt (OJW): Thanks for agreeing to be interviewed in advance of your keynote at the Hyperledger Global Forum. While most of us know you as the author of the Blockchain Revolution (2016), perhaps you could introduce yourself and talk a little more about the Blockchain Research Institute? 

Don Tapscott (DT): Blockchain Revolution is my sixteenth book, and the first I’ve written with my son, Alex Tapscott. All of my work, from Paradigm Shift to Wikinomics and Macrowikinomics, explores the intersection of digital technology with business and society.

Don Tapscott, Blockchain Revolution author and Blockchain Research Institute co-founder

The Blockchain Research Institute (BRI) was established in 2017, a year after Blockchain Revolution was released, to provide a research foundation for enterprise and government leaders to begin exploring blockchain. We gathered a network of the world’s leading experts in a variety of fields to help create over 300 research deliverables, focused on blockchain’s applications in over a dozen different sectors.

We’ve continued expanding our offerings, though – we have released a MOOC in partnership with INSEAD and Coursera, we have put together the world’s largest enterprise-focused blockchain conference, and we are releasing a series of four books this year, the first of which is out now!

OJW: You have been travelling around the world giving keynotes about blockchain. I personally saw you speak in January at the Geneva Blockchain Congress before you travelled to Davos for the World Economic Forum (WEF). Overall, do you think the market is becoming more receptive to blockchain? 

DT: I would call it “uneven and combined development.” In some sectors blockchain/DLT adoption has been rapid, but it’s been downright glacial elsewhere. On the whole, however, the enterprise community is considerably more literate than it was when Blockchain Revolution was first published back in 2016. 

From time to time, I still hear the sentiment that blockchain development has “stalled.” That particular view is deeply misinformed – we have seen a significant growth in production blockchain solutions in the past year.  The previous Internet (of Information) was targeted at the information and media industries. The disruptions were deep and spilled into other industries like retail, but relative to the Internet of Value (blockchain) they are small. 

Why so? Because blockchain targets elements of our economy and society that are more profound than information – assets – everything from money, securities, intellectual property, the data in our identities, deeds, contracts, to cultural assets and even votes.  It challenges the way that we treat valuable information and data assets that are owned too. 

OJW: You wrote for the WEF that bad PR, regulation and technological immaturity are the main obstacles to blockchain adoption. While regulation affects enterprise adoption of blockchain less than, say, cryptocurrencies, what role do software foundations, like Hyperledger, have in solving these issues? 

DT: The Hyperledger community is a core part of the ecosystem governing this historic innovation.  The organizations tackling such stewardship operate on three levels: platforms, application ecosystems, and at the broader cross-industry, societal level. Organizations like Hyperledger govern at the platform level but have proven extremely effective in promoting interoperability too, not just within their own ecosystem of DLTs but more broadly. Meanwhile, organizations like the Chamber of Digital Commerce (CDC) or the BRI provide advocacy and guidance to enable broader institutional changes. 

All of them are crucial, as I see it, in facilitating widespread adoption.

OJW: In your 2012 TED talk, you argued that the four principles of an open world are open collaboration, transparency, sharing, and empowerment through decentralisation. These principles are closely aligned with those of the open source community. Do you think that open source will prevail in the development of lasting blockchain technologies? 

DT: I think that open source is fundamental to the long-term development of this technology. Of course, above the very basic protocols and platforms there will be no shortage of proprietary applications, and that’s to be expected. Fundamentally, though, the success of a blockchain project depends on building and engaging an ecosystem of developers, which lends itself well to open source.  

OJW: Some may remember that, in the early days of the personal computer market, there were many competing offerings. Of course, very few market players survived in the long run – basically Apple and the IBM PC. Do you see a similar situation occurring with blockchain? With many different open source protocols available, will ultimately only a few survive?

DT: The specific offering changes the amount of diversity a market might accommodate, of course. If we’re talking about personal computing, it makes a big difference whether we’re discussing hardware, operating systems, or applications, for example. There’s no question we’ll see greater consolidation of blockchain platforms, but we’ll also see improved platform interoperability. Hyperledger Besu is a good example of the latter.

OJW: Whatever the outcome of the “ledger wars,” would you agree that it makes sense for enterprises to focus on smart contracts? Solidity has been around for a while, but there are now emerging open source smart contract languages such as Accord and DAML (from Digital Asset). Do you think smart contracts will follow a similar evolution to previous business model processing languages, that resulted in BPML (Business Process Modelling Language)?

DT: The areas of innovation that enterprises will, of course, change by industry, but on the whole I do think smart contracts probably have the most immediate impact on the largest number of businesses. This is especially true if your business is approaching blockchain solely as a means of reducing the manual processes involved in conducting business logic, but I think there are more fundamental transformations to work on as well. 

OJW: What role do you think organisations like the BRI and the Global Blockchain Business Council (GBBC) should play in developing the standards required to accelerate blockchain adoption?

DT: The BRI exists to fill the knowledge gap in blockchain and help large enterprise leaders navigate this coming revolution. I have limited knowledge about the GBBC’s work, but I know they play an important role as industry advocates and they do helpful educational work such as the platform they offered this year at Davos. Both organizations, alongside the CDC, are focused on the highest level of stewardship that I mentioned previously – broad, institutional changes to facilitate further adoption. 

The BRI has been supporting various organizations’ efforts to build standards, specifically at the platform level. My most recent research, in fact, specifically explores the Enterprise Ethereum Alliance’s Token Taxonomy Framework – which is part of a truly breakthrough initiative. 

OJW: How can we work to develop standards particularly in the regulated financial services sector? An interesting example is the partnership between Digital Asset and the International Swaps and Derivatives Association (ISDA) to develop a Common Domain Model (CDM)?

DT: The goal should be not just to develop those standards, but to develop the tools necessary to help innovators and companies abide by those standards. Digital Asset’s CDM reference code library is a good example of that. We should also work to provide greater certainty that solutions or products being developed indeed abide by those common standards – certification systems built into testnets, for example. 

If we don’t focus on accessibility, clarity, and certainty, then it will be far more difficult for smaller companies and innovators to abide by those standards.

OJW: Finally, we keep hearing that this is the year that blockchain becomes mainstream, how close or, for that matter, how far are we from achieving this and what could derail this ambition?

DT: There will never be a distinct moment when we realize we’ve “arrived,” and there are already many applications that have reached a level of production that could be considered “mainstream.” In general, though, it will take time to embed this technology into every facet of business and daily life because it challenges very fundamental aspects of how firms and broader industries operate.

Blockchain often forces us to reimagine the role of some very powerful and deeply integrated institutions, which are – by design – not easy to change. It will take time to get there, but compared to where we were even a few years ago, the pace of change is astounding. It’s clear now that to sit this out is to resign yourself to obscurity, and smart enterprises working hard to bring about change. 

Don Tapscott’s keynote, “The Blockchain Revolution – State of the Union,” will be on March 4, 2020, at Hyperledger Global Forum. To register, go here.

Don Tapscott is a world leading authority on the impact of technology on business and society. He authored 16 books, the most recent being the best-selling Blockchain Revolution which he co-authored with his son, Alex Tapscott, who he also co-founded the Blockchain Research Institute with in 2017. Don received an Order of Canada for his leadership in the field of business and innovation, he is a current Adjunct Professor at INSEAD and former Chancellor of Trent University, Ontario. 

Oliver Johnston-Watt is Marketing Director of Blockchain Technology Partners (BTP), a leading enterprise blockchain company.  BTP brings the benefits of smart contracts and blockchain to business by providing Sextant – a management platform that radically simplifies the deployment and ongoing management of distributed applications. Oliver is based in London and is a graduate of the University of Oxford.

Ramping up Roaming: Telekom Innovation Labs New Hyperledger Fabric-Based Solution to Automating the Growing Volume of Telco Wholesale Agreements

By Blog, Hyperledger Fabric

Telekom Innovation Laboratories has built a solution, using Hyperledger Fabric, that simplifies and facilitates processes between telecommunications network providers for commercial use cases in the areas of wholesale roaming, wholesale voice and data on demand.

Network operators are facing big problems in handling increasing volumes of roaming traffic. They have hundreds of roaming agreements with other operators in place that need to be updated, implemented and settled, mostly on a yearly basis.

Due to lack of automation of interconnection agreements and complexity of current processes, operations are slow and require a lot of manual work. This leads to financial losses due to roaming transactions that cannot be properly tracked and charged. These days, agreements are to a large part analogue contracts on paper that need to be proofread multiple times by many people. The agreed commercial terms then need to be implemented into the software systems manually later on. Some network operators exploit the current process to their financial benefit by not implementing agreements at all or only with delays, leading to financial losses and disputes. Typos can also lead to disputes and financial losses. A holistic, analytic view on all agreements is impossible. At the end of the contract period, the contracts need to be settled, which means that volumes need to be compared, discrepancies clarified and fraud deducted, which is another lengthy and cumbersome undertaking

The processes in place are dated and are not fit for expected increase of roaming traffic, especially when IoT roaming and 5G will become more widespread. Current systems are hard to scale and lack flexibility.

We at Telekom Innovation Laboratories believe that, in the future, automated processes need to be in place in order to enable telecommunications providers to deliver even better services to customers and be ready for new technologies and services that are already evolving, for example 5G and IOT. The current processes are simply not suitable for handling the technologies of the future.

Using Hyperledger Fabric at its core, our solution will optimize the process and, more importantly, enhance the trust between telecommunications providers.

The solution has two main layers:

The application layer provides interfaces for the many different processes mentioned above (e.g.,  enabling commercial roaming teams to create, sign and implement wholesale roaming agreements in a fully digitized way). It also has a UI for the commercial managers to interact with.

The network layer provides a solution that enables telcos to install nodes in their own IT infrastructure and join the main network in a semi-automated and effortless way.

Between these layers, an API enables the flow of data and transactions.

The current version focuses on the digital creation and signing of wholesale roaming discount agreements. A digital solution immediately leads to more transparency across internal teams (e.g., finance, legal, commercial), reduction of third party dependencies, reduction of bad debts and a better cash flow situation and therefore increases the profitability of telecommunications providers.

One of the reasons to pick Hyperledger Fabric was the integrated certification authority (CA). With this component, we can ensure that transactions are linked to the legitimate actors, which is very important from a legal perspective. All network operators have signing regulations and processes in place, which ensure that only certain persons inside the organization can sign contracts, while others can only create or edit them. Being able to mirror this process in our solution was a key requirement.

Another reason for our choice was the fact that Hyperledger Fabric is a reliable open source solution backed by a large developer community. We at Telekom Innovation Laboratories believe that the decentralization of blockchain cannot just be a functional aspect but needs to extend to licensing as well. This is the only way to  ensure that code can be reviewed, changed, and improved by all participating parties in a blockchain network without having to tackle complex licensing issues. Licensing is challenging already when it comes to bilateral relationships, but is almost impossible to handle if there is a multitude of parties involved in the same system.

In order to ensure maximum control for each network operator joining our system, each operator runs its own full organization on the Hyperledger network. Every organisation entity consists of the following components: peer, frontend, database, certificate authority (CA). The components are packaged as docker components and groups as Pods in Kubernetes and can be installed on the premises of each client organisation that joins the network. There are several reasons for choosing this approach:

  • Each participant in the network can have control over its data (contracts) as well as administrative rights to the technical components. Sensitive data can therefore be stored on premise or on private cloud or even dedicated hardware, managed by the organisation.
  • Using the distributed blockchain architecture, a copy of the ledger is located on multiple organisations at the same time. Transactions flow is implemented by the orderer in the core network, where the consensus algorithm is implemented. This allows for much higher security, as there is no single point of failure and each organisation participates in the networks at the same level as all other organisations.
  • Private certificate authority (CA) allows each organisation to issue cryptographic materials needed  to connect to the network, sign contracts and manage transactions. This allows for higher security and flexibility compared to a single centralized CA.

The system currently uses a single blockchain channel, which contains all transactions by all organisations. This means that all transactions are visible by all participants in the channel. However, no contractual data is stored on the ledger. It contains metadata for each transaction that has been executed (e.g., signing a contract by the other party and agreeing to its terms). The hash can be computed based on the raw contract data and therefore can be used as proof in case of dispute that the actual parameters in the contract have been agreed by both parties. A copy of the ledger is distributed in all organisations, but the actual sensitive data is located only at each of the organisations’ respective databases and is not visible to other parties in the network. This ensures that there is a high level of security due to the large amount of participating actors in each transaction, while at the same time keeping up the required confidentiality when it comes to actual commercial data.

The contract data is stored on MySQL server running within the bounds of each individual organisation. This database stores data only related to its own contracts, so there is no distributed contract storage within the network.

Contract data are synchronized only between participating organizations when a transaction occurs (e.g., when a new contract is being created). This synchronization takes place between the frontend components of each organisation. They use a separate API that uses TLS encryption and mutual authentication to secure the transport of data.

A major feature of our solution are installation packages and scripts that allow an easy on-premise creation of a new organization. Through this, we already managed to add major operators to our blockchain network.

Currently, we are also working on integrating the end of period settlements into our solution. As we approach production, we will move to using a RAFT ordering service.

Portland state university BUSINESS blockchain certificate program

By Blog, Education

Portland State University is in its first year of its fully online, six-course Business Blockchain Certificate. The intensive academic program targets graduate and upper division undergraduate students and is also open to non-degree seeking community members. The for-credit program is the first of its kind and, unlike other universities, the program focuses on business students rather than engineering or computer science students.  

The program is supported by a board of advisors from well known organizations in the region and across the United States. PSU has formed partnerships with Hyperledger, the Global Blockchain Business Council (GBBC) and the Oregon Enterprise Blockchain Venture Studio in an effort to produce world-class blockchain curriculum that meets the challenges of a quickly evolving and disrupting force in business.  

Through this certificate, The School of Business is responding to the needs of the business community as rapid advances in technology create workforce skills gaps. The employment forecast for 2019-2024 shows that demand for blockchain-related skills are the most desired by companies across functions like finance, insurance, digital media and supply chain. Regionally this demand has doubled since 2010, with the top seven northwest companies looking for blockchain professionals to drive this tremendous growth.

The objective of the Business Blockchain Certificate is to provide students with the ability to make informed decisions about whether, when and how to apply distributed ledger technology to real business and social problems. The program employs a hands-on and interdisciplinary approach, reflecting the diversity of skills necessary for success in this rapidly-changing field. Graduates of the program will have practical experience writing proposals for blockchain-based business networks, solving technical problems, designing governance protocols, determining success metrics, and building active blockchain networks with smart contract capabilities.

The coursework and projects, lab assignments, and interactions with guest speakers equip students with the ability to evaluate technical, business and ethical problems; interact directly with distributed ledger technology and its developers; and respond effectively to future technological advances in data handling in their companies and industries.

PSU student teams won the national Trueup Blockchain Challenge competition in 2018 and 2019. Additionally, a team of PSU students is currently one of five finalists in the year-long Blockchain for Logistics and Supply Chain Management Innovation Challenge hosted by Arizona State and Sponsored by the US Military.    

The program’s co-founders, Dr. Kristi Yuthas and Dr. Stanton Heister, recently published an article titled The blockchain and how it can influence conceptions of the self in the journal Technology in Society.

Deploying Hyperledger Fabric in Production

By Blog, Hyperledger Fabric

In recent years, a number of economic sectors have seen the great promise of blockchain and are already using or piloting it in different use cases. But proof-of-concept projects are often led by evangelists, developed in R&D, and always in controlled environments. Moving to production requires stakeholder buy-in and can be a real challenge, especially at the current time with blockchain.

The Hyperledger Hyderabad Meetup organized a meetup to demonstrate the potential of Hyperledger technologies and discussed the challenges related to the production deployment of Hyperledger Fabric. This session was headed by a startup team out of the Hyperledger Hyderabad community itself, called ChitMonks, who have set a benchmark in their use case in the chit fund industry. 

The chit fund industry, with estimated assets under management (AUM) of ₹1.50 lakh crore, involves a great deal of paperwork. In some instances, it forms the backbone of the informal economy in developing countries like India. This results in drudgery for both the foremen (who organizes the chits) and the regulators (the State governments). 

Administration of chit funds through companies are happening manually. Every time a company wants to start a chit, they have to submit a huge pile of documentation on a monthly basis to the registration and stamps department, which is the regulator. Consequently, there is a lack of transparency for subscribers, and audits need to be done to ensure the government and chit fund company have matching documentation. The information gap between the chit fund company and the regulators produces a loophole for frauds, which are hard to trace back.

The approach of ChitMonks is to place a private blockchain-based, consortium-driven infrastructure and establish a process-based trust, by bringing all the stakeholders involved in the process to the same platform of blockchain.

Many new service providers to join….………….

Technical Architecture 

The three major entities involved in the process are:

  • Foremen: it’s a consortium of all the chit fund companies.
  • Regulators: it’s a consortium for all the regulatory entities (generally the local government bodies). 
  • Subscribers: they are the end beneficiaries of the chit fund companies.

The foremen and regulators act as the two organizations in the network. And each of the organizations has two peers each. The organizations also have their respective C.A. (Certificate Authority) for letting any new member join the consortium.

  • A channel is established between the two organizations to keep data in synch between regulators and the foremen.
  • The chaincode is framed around the Chit Funds Act, 1982, passed by Indian legislative. This chaincode takes care of all the guidelines like commissions by foremen, a form of chit agreement, filing of chit agreement, minimum capital requirements for the commencement of a chit, creation of a reserve fund by a company and many more aspects of chit fund.
  • The orderers follow Raft ordering service, after being maintained on Kafka ordering service for quite some-time.
  • The state DB chosen here is couch DB, after testing it with Go level DB, which can handle complex data and adds rich querying practices. 
  • Here the ledger holds only relevant data for both the organization’s, keeping a separate off-chain database for specific purposes.
  • The infrastructure is designed as such where a foremen organization can own and maintain organization nodes. Typically, a big organization can own the infrastructure, medium and small organization can be part of consortium org/nodes. This makes the blockchain network more self-sustaining and more decentralized.  

So, here the blockchain system is used in a very optimized way by keeping only the shared data over the system. To make this complex system easily accessible for both organizations, each of the entities has different applications for their purposes.

As already mentioned, ChitMonks serves its platform to more than 700+ chit fund companies. Data privacy was the biggest concern for them, since the consortium of all the chit fund companies are structured as an organization here, and they all have access to the same state DB. To ensure data privacy, ChitMonks used private data collection introduced by Hyperledger Fabric in its 1.4 release. In this case, each transaction is encrypted, and the keys to check data are shared between the regulator and chit fund company over the private data collection provided by Hyperledger Fabric’s latest release.    

Challenges Encountered

Asset Modeling – Asset modeling helps to define the entities and assets involved in the process of business.  Challenges include the incipient regulatory framework and the relatively limited experience of managing large amounts of data with respect to entities (i.e., who will own what data and hierarchy involved each level of the process). While there haven’t been verifiable data breaches of blockchain backbones to date, there have been deficiencies in the implementation of smart contracts, mostly due to failures in coding. But a well-defined set of terms and conditions from the government authorities (which is also the regulatory and one of the organizations in our Blockchain infrastructure) for  the chit fund business helped ChitMonks to encode an ultimate and sustainable asset modeling. 

Testing chain code – Hyperledger Fabric provides us an immutable infrastructure. So, it’s important to test the chaincode well before deploying it. ChitMonks took the approach to perform unit testing at every change to follow up on potential bugs.   

Docker infrastructure – Containers might thus move from one host to another, especially while scaling the number of containers up or down or during container redeployments. There is no static relation between hosts and services they are running anymore! For troubleshooting, this means one must first figure out which host is running which containers. And, vice versa, when a host exhibits poor performance, it’s highly valuable to be able to isolate which container is the source of the problem and if any containers suffer from the performance issue.

Continuous Integration tools (CI) such as Jenkins can build and deploy Docker images across application environments very easily. Builds can be automated and also can be monitored efficiently using CI administrator console.

Maintaining the Kafka cluster – Initially, ChitMonks established its Hyperledger infrastructure with Kafka-based ordering services. Kafka provides a scalable multi-orderer infrastructure and poses a viable fault-tolerant solution for Hyperlуdger Fabric infrastructure, but it required us to maintain zookeepers along with it in production, which added a layer of complexity. So, ChitMonks have shifted to Hyperledger Fabric 1.4, which allows raft ordering services.  

The Raft consensus is a mature consensus algorithm and is easier to implement on a large scale than Kafka. It can extend a network with new organizations, as we don’t need to rely on a third-party Kafka cluster. In the previous versions of the platform, it was impossible to change a consensus type of a blockchain network without full redeployment. However, Hyperledger Fabric v1.4.2 introduced a mechanism that makes it possible to migrate a network from a Kafka consensus to a Raft-based one. And Hyperledger has provided a very easy step-by-step guide for migrating from Kafka to raft consensus.

Conclusion

The meetup was received with a very enthusiastic response. Many of the attendees were very happy to see a local startup deploying production-grade applications. The ChitMonks engaged well with the audience to help them understand the difference between a POC and production level applications and shared their perspective on scaling a blockchain-based product!

Looking ahead to Hyperledger Global Forum

By Blog, Hyperledger Global Forum

The upcoming Hyperledger Global Forum, March 2-6, in my hometown of Phoenix, Arizona, provides us with an opportunity to come together face-to-face and learn what is happening in the Hyperledger community. 

With the chance to collaborate in person, we can align on how we think about fundamental questions, such as:

  • How do we meet the growing need for interoperability?
  • What can we do to achieve an inclusive community?
  • How can we build the blockchain ecosystem?

While at Hyperledger Global Forum, here are some sessions that will help us answer the questions above.

The growing need for interoperability

Before joining Accenture this time last year, I spent two years with the Linux Foundation as a community architect for Hyperledger. With 15 different projects in the greenhouse, maintainers share a baseline understanding of each other’s work, but community collaboration tends to stay within project silos.

The thing is, multiparty systems like blockchains are a team effort. They rely on an ecosystem of people working together. To reach the technology’s full potential, we need interoperability between every person, every platform, and every project.

As a result, the dialogue in the community is shifting from “Which chain will rule them all?” to “How do I get my chain to work with yours?” The answer hinges on ecosystem collaboration. 

On Wednesday, Accenture’s Giuseppe Giordano and Peter Somogyvari’s session, “Connecting Ecosystems: Blockchain Interoperability,” will give an update on our development work and unique approach to interoperability for permissioned blockchain networks with Blockchain Integration Framework, recently open sourced to Hyperledger Labs.

Inclusive collaboration by design

If you ever attended a Hyperledger event or meeting, you have likely heard the phrase “All Are Welcome Here.” Ensuring we fulfill this commitment is table stakes, for our global community, for our code, and for the future adoption of these cutting-edge technologies. There are a number of sessions related to this important topic that will benefit each of us.

To kick off the event on Monday evening, March 2 at 6pm, Accenture is sponsoring a diversity happy hour. We will be thinking through actions we can all take to make our community more diverse and inclusive in 2020.

On Thursday, Hyperledger Marketing Committee co-chair and Accenture’s Alissa Worley and I will host a workshop on unconscious bias. With the help of VR, this immersive experience will help participants understand what unconscious bias is and how to mitigate it.

I am honored to serve alongside IBM’s Swetha Repakula as the first women on the Hyperledger Technical Steering Committee. Swetha and I will lead a session on Wednesday about how we create an inclusive Hyperledger community. We will share a number of tips about making people feel welcome and being open to contributions. These ideas apply beyond Hyperledger tools to any open source project. 

Building the ecosystem

Building the ecosystem starts before the technology choices are made. We need to make sure that we define the right governance models with our clients, our partners, and our regulators. There are a number of talks that will shed some light on how to lay a successful foundation, ranging from making the case for blockchain initiatives to governing DLT networks. 

If you are like me, you may have got into the blockchain space because of the technology’s potential for positive impact. I will be curious to hear Sheila Warren’s keynote to learn how WEF is using blockchain to change the world. 

Looking ahead

At Accenture, we see blockchain technology flourishing in three main areas: financial services, supply chain and identity.

From hosting the Hyperledger Maintainers’ Summit, contributing code, and supporting Hyperledger Global Forum as a diamond sponsor, it is great to see Accenture further our commitment to the blockchain open source ecosystem. 

I am looking forward to seeing you in March, as we learn from one another and grow the Hyperledger community. Lastly, while you are in Phoenix, you cannot miss having a bite and a beverage at Four Peaks Brewery, taking a hike at Camelback Mountain, or visiting the Heard Museum Indian Fair and Market.

Looking back on 2019: Identity, blockchain and Verified.Me

By Blog, Hyperledger Global Forum

It feels like it wasn’t that long ago that we all imagined 2020 would be one of those years far in the future when everyone would have a sort of robotic personal assistant, microchip implants or flying cars. Well, the first electric “flying” vehicle is scheduled to be tested next year by ride-sharing giant Uber, and AI personal assistants and microchip implants are a reality.  

What I imagined the future would look like revolved around technology serving humanity and helping solve societal problems. We’ve seen examples of technology, like blockchain, being used to enable digital commerce while also fighting corruption, deterring fraud and, mostly importantly to me, solving problems with today’s identity landscape. 

Identity-related digital fraud is one of the direst challenges with today’s digital economy. Whether it’s trouble with credit card fraud, data breaches of varying sizes, the advent and rise of SIM swapping fraud or identity theft, bad actors are becoming increasingly sophisticated at stealing our data through innumerable channels. Just last year, over five billion records were exposed through at least 6,515 publicly reported data breaches. In Canada, CPA Canada’s 2019 Annual Fraud Study(1) found that 70 per cent of Canadians are more concerned about fraud today than they were five years ago, 86 per cent are familiar with identity theft and credit card fraud and almost 80 per cent have experienced email and telemarketing fraud. 

Think this doesn’t have an impact on your personal life? Take a quick visit to Troy Hunt’s haveibeenpwned.com to see where your email address has been publicly leaked in reported breaches, the vast majority of which occured in the latter half of this decade. 

These concerning stats serve to both scare and encourage us to continue to develop solutions that protect people’s data. From conversations around FaceApp’s face-aging filter opening the door to hackers to stories about how people still write their passwords on a piece of paper, it’s clear there’s still lots to be done to mitigate risk. We believe that taking care of personal data should be a combined effort between users and technology providers – and we look forward to doing our part at SecureKey. 

My vision for 2020 is seeing blockchain reach its full potential in helping participants in the world’s digital economy arm themselves against bad actors. My vision is to solve the problems of today’s identity landscape and help consumers – and their data – move forward into the next decade with greater privacy, security and consent-driven tools at their fingertips. 

My personal goal is to move beyond society’s justified milieu of fear and frustration toward online services, instead making online service delivery trustworthy and cost effective. I want to grow online transactions for business while also making it simpler, more convenient and respectful of privacy for all of us who want to do more online.

In the last year, there were a number of important milestones, amazing advancements and new use cases of blockchain technology:

Welcome Hyperledger Fabric 2.0: Enterprise DLT for Production

By Blog, Hyperledger Fabric

As the first project of the Hyperledger greenhouse in 2016, Fabric introduced its v1.0 release in July, 2017. Since then, a number of enhancements and new features have been implemented based on the feedback from industry and community. 

To celebrate the 4th birthday of Hyperledger Fabric, what can be a better gift than the major release of v2.0?  Before we jump into the new additions and features in this release, we think this major milestone is a good time to reflect on some of the key design objectives behind Hyperledger Fabric and how it has evolved to this point.

An open, proven, enterprise-grade blockchain framework

Echoing the Distributed Ledger Technology (DLT) trends and requirements in finance, supply chain and other industries, Hyperledger Fabric was initiated by tens of leading companies globally in early 2016. Since then, under the support of the Linux Foundation, hundreds of open source developers have been working together to design and implement a practical DLT framework to meet these real demands by integrating the advanced techniques of databases, networking, distributed consensus, and cryptography.

Hyperledger Fabric has quickly become one of the most popular open source DLT projects, with hundreds of deployments worldwide. In 2019, 30 companies in the “Forbes Blockchain 50” were using it.

Due to its open source model and popularity, Hyperledger Fabric has been adopted by major Cloud Service Providers including Alibaba, AWS, Azure, Baidu, Google, Huawei, IBM, Oracle, SAP, and Tencent.

What is Hyperledger Fabric?

Hyperledger Fabric is an enterprise-grade, distributed ledger platform that offers modularity and versatility for a broad set of industry use cases. Rather than a permission-less system where anyone can transact and access data, Fabric offers a permissioned, secure, and scalable platform that supports smart contracts and data privacy. This architecture allows for solutions developed with Fabric to be adapted for any industry, thus ushering in a new era of trust, transparency, and accountability for businesses.

While members of a network work together, businesses still often need to maintain separate relationships within their networks to keep certain interactions private. For example, a purchaser might be selling the same product to different sellers at different prices.

Fabric provides a spectrum of options to support transaction and data privacy. You can use separate “channels” if you need total transaction isolation between member organizations. And you can use “private data” within a channel if you’d like to keep data private while writing hashes on a shared ledger as transaction evidence. Private data can be shared on a need-to-know basis and then verified against the on-chain hash evidence. 

Why Hyperledger Fabric?

Because Hyperledger Fabric has matured in the open source community with a focus on enterprise use cases, it has evolved to support the features and production operations that enterprises demand. Here’s a few of the features that make Fabric unique relative to other distributed ledger technologies:

  • Permissioned and modular architecture
  • Flexible endorsement model for achieving consensus among transacting organizations
  • Pluggable consensus for transaction ordering and block distribution
  • Open smart contract model – flexibility to support various solution and data models (account model, UTXO model, structured data, unstructured data, etc)
  • Data privacy – complete transaction isolation using “channels”, or share private data on a need-to-know basis using private data “collections”
  • Low latency of finality/confirmation
  • Multi-language smart contract support: Go, Java, Javascript
  • Support for EVM and Solidity
  • Governance and versioning of smart contracts
  • Queryable data – keyed queries, range queries, and JSON queries on-chain, and event hooks to integrate data into your preferred database or analytics engine
  • Designed for continuous enterprise operations, including rolling upgrades and asymmetric version support

Hyperledger Fabric 2.0: The Latest Evolution

The evolution continues and we are excited to see the next generation! Let’s welcome Hyperledger Fabric v2.0 by taking a quick glance at the highlighted features compared to the v1.0 release:

  • New chaincode lifecycle management. The totally redesigned chaincode lifecycle management process introduces decentralized governance for smart contracts, with a new process for installing a chaincode on the peers and starting it on a channel. The new Fabric chaincode lifecycle allows multiple organizations to come to agreement on the parameters of a chaincode, such as the chaincode endorsement policy, before it can be used to interact with the ledger.
  • New chaincode application patterns for collaboration and consensus. The same decentralized methods of coming to agreement that underpin the new chaincode lifecycle management can also be used in your own chaincode applications to ensure organizations consent to data transactions before they are committed to the ledger. Additionally, organizations can now extend their copy of a chaincode to meet their individual requirements. For example, an organization can add its own chaincode validations to better protect the organization’s specific interests before agreeing to endorse a transaction. As long as there is consensus on the chaincode execution results among the required endorsers for a given transaction, the transaction will be committed to the ledger as in prior releases.
  • Data privacy on a need-to-know basis. In addition to the traditional use of channels and private data collections to share data among a subset of network members, the new implicit organization-specific private data collection feature in v2.0 allows organizations to privately share data with other organizations in the channel on a need-to-know basis, eliminating the need to define channels or private data collections for many combinations of members. Hashes on the channel ledger serve as transaction evidence to ensure that private data can be verified when shared, or later audited as needed.
  • New external chaincode launcher. The external chaincode launcher feature empowers operators to build and launch chaincode with the technology of their choice, removing the requirement to give the peer access to a Docker daemon. For example, an operator may decide to deploy chaincode as an external service in a Kubernetes pod.
  • New consensus type of Raft. The new Raft consensus for ordering service introduced in v1.4.1 is now the recommended consensus service, eliminating the dependency on an external Kafka cluster. This makes the ordering service a decentralized governing model that can be provided by multiple ordering organizations. Additionally, an ordering node can now choose which channels it will serve instead of the legacy requirement of serving all channels. This brings an important scalability improvement to better support a large number of channels and transactions, not to mention the obvious privacy improvement.
  • Performance improvements. A number of performance improvements have been added throughout the v1.x releases and in v2.0. A new cache has been added to the peer to improve performance when using CouchDB as the state database. Additionally, transaction validation is parallelized in the commit phase. The ordering node message processing flow has been optimized to remove redundant checks, and the write block processing is now asynchronous. Chaincode queries can be paginated, making it feasible to support large result sets with high performance. It’s now possible to achieve thousands of TPS in practice.

Hyperledger Fabric 2.0 is already getting strong interest within the blockchain community:

“The release of Hyperledger Fabric 2.0 is an important step forward in the on-going evolution of DLT, and was developed based on feedback from real-world use, including improved chaincode management capabilities and performance enhancements.

Five Healthcare Projects Powered by Hyperledger You May Not Know About

By Blog, Healthcare

The New Year brings about various resolutions for millions across the globe. For many, that means putting more focus on their physical and mental health. Blockchain’s ability to revolutionize healthcare is undeniable. When applied to healthcare, blockchain is a shared platform that decentralizes health data without compromising the security of sensitive information. For example, patients can potentially use their own signatures, combined with a hospital signature, to unlock data to provide secure access to medical information for use in treatment. Patients could have full control of their medical information, selecting the information they want shared and viewed by providers or doctors. This model lifts the costly burden of maintaining patient’s medical histories away from hospitals. Also, counterfeit medicine is a big issue pharma companies face in their everyday operations since there are many stakeholders involved in the supply chain. Recall of drugs and avoiding counterfeit drugs from entering into legit marketplaces will help in reducing the losses and improving service delivery to the end customer. Blockchain could be used to maintain the entire supply chain in healthcare.

Below is a list of some interesting healthcare applications powered by Hyperledger technology you may or may not have known about:

Axuall – Axuall is a digital network for verifying identity, credentials, and authenticity in real-time using the Sorvin Network and Hyperledger Indy. The Axuall network is currently in pilot with Hyr Medical and their 650+ physician network in addition to two other health systems. Physicians’ time is better spent practicing medicine than filling out redundant, repetitive credentialing paperwork consisting of unchanging information. Using Axuall’s digital credentialing network, physicians will be able to present fully compliant credential sets to participating healthcare systems and medical groups they are affiliated with or applying to. Utilizing the cryptographic constructs from Hyperledger Indy, healthcare organizations will be able to verify the validity of a physician’s credentials – spanning medical education, training, licensing, board certification, work history, competency evaluations, sanctions, and adverse events – ensuring compliance with industry standards, regulatory mandates, and health system bylaws. 

KitChain – LedgerDomain joined forces with other industry leaders like Pfizer, IQVIA, UPS, Merck, UCLA Health, GSK, Thermo Fisher, and Biogen to build out a pilot on Hyperledger Fabric called KitChain. Scoped and developed over the course of two years, KitChain aims to demonstrate a robust collaborative model for managing the pharmaceutical clinical supply chain, creating an immutable record for shipment and event tracking without the need to resort to paperwork and manual transcription. KitChain has two major components: a frontend mobile application and a backend blockchain server. The backend was implemented in Golang and used Hyperledger Fabric, the LedgerDomain Selvedge blockchain app platform, and LedgerDomain’s DocuSeal framework, encompassing smart contracts and application logic. As such, the pilot has a fully functioning highly secure blockchain backend.

MELLODDY Project – This drug discovery project uses Amazon Web Services technologies to execute Machine Learning algorithms from academic partners on a large scale. The data never leaves the owner’s infrastructure and only non-sensitive models are exchanged. A central dispatcher allows each partner to share a common model to be consolidated collectively. To provide full traceability of the operations, the platform is based on a private blockchain and uses Substra, a software framework for orchestrating distributed machine learning tasks in a secure way. Substra is based on Hyperledger Fabric. MELLODDY is designed to prevent the leaking of proprietary information from one data set to another or through one model to another while at the same time boosting the predictive performance and applicability domain of the models by leveraging all available data. The MELLODDY consortium consists of 17 partners: 

  • 10 pharmaceutical companies: Amgen, Astellas, AstraZeneca, Bayer, Boehringer Ingelheim, GSK, Janssen Pharmaceutica NV, Merck KgaA, Novartis, and Institut de Recherches Servier 
  • Two academic universities: KU Leuven, Budapesti Muszaki es Gazdasagtudomanyi Egyetem
  • Four subject matter experts: Owkin, Substra Foundation, Loodse, Iktos
  • One large AI computing company: NVIDIA

MyClinic.com – Medicalchain was one of the first healthcare blockchain companies to join the Hyperledger community, signing on as a member in 2017. The company’s ethos is to empower patients to have access to their medical records. Providing patients with direct access to their data unlocks the barriers we face in healthcare today such as patient choice and interoperability issues. A doctor-led team based in the UK, Medicalchain trialled the first telemedicine consultation using blockchain technology.  The company’s first blockchain-based product to market, MyClinic.com, makes it easy to schedule appointments, review medical reports and request further investigations or assistance using an Android and iOS app. Now the company is set to focus on scalability with the view to onboarding clinics and patients locally, nationally and internationally.

Verified.Me – SecureKey launched its innovative and in-demand network to Canadian consumers in early 2019. Verified.Me is a blockchain-based digital identity network built upon Hyperledger Fabric 1.2 that enables consumers to stay in control of their information by choosing when to share information and with whom, reducing unnecessary oversharing of personal information. Sun Life Financial has signed on as an early adopter and the first North American (health) insurer, making it easier for their clients to do business with the company.  Dynacare, one of Canada’s largest and most respected providers of health and wellness solutions, has joined the Verified.Me network. Dynacare’s participation will make it easier for Canadians to verify their identities as well as gain safer and faster access to their health information.

Curious about blockchain and advances in healthcare? Contribute to the conversation by joining the Hyperledger Healthcare Special Interest Group (HC-SIG). Open to anyone, the SIG was created to offer healthcare professionals and technologists a forum to discuss the implementation of technology solutions using blockchain technologies in general like Hyperledger frameworks and toolsets in specific.

How Hyperledger Besu Will Help Solve the Pharmaceutical Waste Problem in the U.S.

By Blog, Healthcare, Hyperledger Besu

The problem of surplus medication is getting increasingly serious. Each year, tons of prescription drugs remain unused in clinics, assisted living facilities, and at individual patients’ homes. Often, the law demands that any unused medications be destroyed, which results in a whole complex set of problems. 

On the one hand, about $2 billion worth of prescription drugs are wasted every year. On the other hand, one in every three Americans cannot afford their prescribed medications due to the high cost or absence of medical insurance. At the same time, there is no unified procedure for using surplus medications and making them available to those who need it. 

Another issue to consider in this context is the cost of unused drug disposal, which can be around $1.25 per pound. The rules require that unused drugs be disposed of through incineration that creates additional environmental concerns. 

The obvious solution to this complex problem is establishing a mechanism for returning the unused medications and offering them to patients who need them. In fact, the drug donation and reuse programs have been researched for more than twenty years, but only 38 states have passed laws on drug reuse as of now. 

At the same time, the implementation of these laws gives hope that the multi-faceted problem of surplus drugs can be resolved. However, to achieve true effectiveness and prevent misuse, such programs need to take into account many practical aspects: 

– Control over the donated drugs’ quality and expiration. Of course, to be accepted, drugs must be unexpired and their packaging must be intact. 

– Motivation for pharmacies to act as drug acceptance facilities. Participation in the drug donation program has its costs, which pharmacies are not too eager to bear. 

– Motivation for clinics and patients to donate unused drugs. The law prohibits selling medications, thus, their owners should be motivated in a different way. 

– Data security. Medication-related data is highly sensitive and needs special protection from unauthorized access. 

How technology can help 

Our experience with blockchain and distributed applications proves that these technologies can become the core of an effective and secure platform for unused drug donation and redistribution. It resolves the problems of data security and traceability and can help to automate a number of processes. 

Together with the Save Pharmaceutical project, Adoriasoft is now building a blockchain-based platform to join drug donors (clinics, assisted living facilities, individual persons), drug repositories (pharmacies), and patients. The solution will be a multi-functional product allowing donors to donate the medications they do not need, and pharmacies to approve or reject the donations and, ultimately, to provide them to patients. 

We are using Hyperledger Besu as the base technology for this project. By choosing Hyperledger Besu, we plan to leverage the benefits of the protocol to enable transaction processing. Furthermore, we see Hyperledger Besu as a platform for building a permissioned enterprise-scale network to serve the drug repository system. 

In view of the high sensitivity of healthcare data that is going to be exchanged in the network, the transactions will be processed via smart contracts executed on Hyperledger Besu. Only the parties directly involved in the transaction will have access to its details. 

At the same time, blockchain provides the means of controlling the entire transaction flow from the drug donation by the owner to its final assignment to the patient. The platform will include a mechanism of monitoring the pharmacy income from reselling the donated drugs and distributing it among the other participants. 

Since the law explicitly prohibits donors from demanding payment for the drugs they donate, there should be other methods of motivating them to participate in the program. The state laws establish a tax deduction for drug donation, but our product can include an additional compensation in the form of a tradable digital token. 

The tokens issued on the blockchain can be used towards a discount on the platform or exchanged for other assets. The same tokens can be issued to pharmacies, too, to attract them to the program. 

Blockchain-based drug repository networks are going to be a true quantum leap in the healthcare industry, on the one hand, bringing significant cost savings, and, on the other hand, making medications accessible to patients who were otherwise unable to purchase them. We are proud to be a part of a project of such a social impact and to make the knowledge accumulated by the Hyperledger community serve this noble cause.

Hyperledger welcomes the Climate Action & Accounting Special Interest Group

By Blog, Special Interest Group

Hyperledger has launched the Hyperledger Climate Action & Accounting (CA2) Special Interest Group (SIG) to facilitate focused technical, business and global-level conversations and projects related to appropriate use cases for blockchain and compatible emerging digital technologies across the climate sector. 

For several years now, climate science has had an unequivocal consensus that global emissions should peak by 2020 and take a sharp decline to zero by 2050. 2020 is now here and yet we are nowhere near this goal. At a critical inflection point in the history of this planet and the global effort to prevent irreversible climate damage, this Hyperledger SIG is launched in an outmost timeline fashion to help bridge action between planet, policy, technology and economy.

SIGs gather community members from an industry segment to work on domain-specific problems and create an environment for open discussion, document co-creation and solution proposals. Hyperledger now has nine SIGs, including ones focused on healthcare, telecom, trade finance, supply chain and social impact.

Climate change is recognized globally as both a crisis and an opportunity requiring transformational change to attain sustainable societies and economies. Urgent action at a global scale is crucially important to achieve the goals of the 2015 Paris Agreement (i.e., UN global climate accord). Five years later, the World Economic Forum (WEF) Global Risks Report 2020 highlighted “Climate Action Failure” as the top risk – ahead of all other major risks such as war and trade conflicts. Concerted action is often fraught with mistrust and lack of transparency among the scope of actors (countries, subnational governments, companies, individuals) due to uncertainty of distributed responsibilities and clashing incentives at the short-term level. Whilst the Paris Agreement is a globally encompassing framework to prevent warming above 1.5oC (relative to pre-industrial levels), it still lacks a clear mechanism enabling actors to “speak the same language” when recording and governing the use of climate-relevant data and verified actions. 

Distributed ledger technology (DLT) and other emerging digital solutions have the potential to provide trusted record-keeping processes, data consensus and rules automation — crucially needed components in order to align actors, accelerate mitigation and adaptation action, and mobilize the trillions of dollars of finance required annually. Hyperledger’s ecosystem and DLTs are central to the creation of a global and open climate accounting system that helps integrate all actors and actions under the same planetary goal. The Climate Action & Accounting SIG has launched to leverage Hyperledger frameworks and the Linux Foundation’s know-how for the development of an open source and decentralized climate accountability network that both operationalizes transparency (i.e., Article 13 of the Paris Accord) whilst enhancing each actor’s personal privacy, security, and control.

The scope of the SIG is defined by the terms climate action and climate accounting:  

Climate Action is a broadly encompassing term that involves all climate-relevant actions (e.g., policies, programs, technologies, goods, services) taken by actors (e.g., states and non-state actors such as businesses, cities, individuals). This covers the range from emission generating activities to the broad set of actions encompassed within climate mitigation and adaptation and its associated finance mechanisms.

Climate Accounting, on the other hand, is referred by the SIG as the encompassing term that involves all processes of recording climate-relevant information/data. This ranges from the physical state of the planet to the list of all climate actors, their broad set of climate actions and agreements in respect to the shared account of the climate challenge.

In other words, whilst climate action occurs in the real world, climate accounting is recorded in the digital world.

Through open and participative discussions, the SIG will help build the relationship between both climate domains and consolidate technological tools to do so.

The new SIG is led by two co-chairs: Martin Wainstein, PhD, and Tom Baumann. Martin is the founder and lead researcher at the Yale Open Innovation Lab at the Center for Business and the Environment at Yale, climate advisor to the Spatial Web Foundation, and manager of the climate & energy finance projects at the Digital Currency Initiative of the MIT Media Lab. Tom Baumann is the founder and co-chair of the Climate Chain Coalition, co-chair of the INATBA Climate Action WG (International Association of Trusted Blockchain Applications), former international chair (2014-2019) of ISO’s climate change standards committee, as well as co-founder of several start-ups including Xpansiv, Adaptation Ledger, ClimateCHECK, GHG Management Institute, Collaborase, and NovaSphere.

The mission and goals of the Hyperledger CA2 SIG is to foster a collaborative network of climate, DLT other emerging technology organizations (i.e., universities, NGOs, government, startups, corporations, multilateral development banks, etc.) that can create a center of gravity around the role of DLT and open source software to address challenges in the global climate action, policy and digital accounting space. 

A focus point of the SIG would be to turn this network into action under a common open source project that defines shared protocols, standards, and platform tools for a globally integrated climate accounting system to be operationalized, and meet requirements by emerging initiatives like the FSB TCFD (Task Force for Climate-Related Disclosure). This open climate project can act as a shared initiative where participants can contribute value to and share explorations in the use DLT alongside other emerging technologies such as IoT (Internet of Things), big data, and machine learning to address the challenge of keeping a transparent climate accounting system towards the climate targets set in the 2015 Paris Agreement.

The SIG community will take initiative to specifically address and develop:

  • Compile completed, ongoing, and proposed future activities related to blockchain for climate action & accounting
  • Create a directory of organizations and initiatives involved with blockchain and the climate space (map of organization location, contact person, description, website, etc.)
  • Consolidate the architecture of an integrated system, involving multiple blockchain mechanisms connected through shared protocols, allowing contractual automation in the link between finance and climate value flow based on the agreed physical parameter of the Earth system
  • Identify Hyperledger tools and frameworks to develop and maintain a single record-keeping ledger with global consensus (i.e., a ‘ledger of ledger’ where all parties agree)
  • Propose and define shared protocols and standards to allow interoperability across the climate accounting system and integrated platforms
  • Compile of best practices, lessons learned, and recommendations to stakeholders (policymakers, technology developers, etc.)
  • Support events (e.g., at blockchain and climate conferences such as COP) and related activities for collaboration among members and stakeholders.
  • Propose, discuss and define a longer-term strategic vision of an open innovation consortium that can help steward, fund, and maintain an open source climate action and accounting project and system
