Mentorship at Hyperledger: Four Interns Share Their Appreciation for Great Mentors

By | Blog, Hyperledger Fabric, Hyperledger Iroha, Hyperledger Sawtooth

If you read about the projects that Hyperledger’s summer interns have just completed, you’ll quickly see that these are serious internships that come with the prize of greater knowledge, skills, and connections with the technical community. One of the most important of these connections is the connection to a great mentor.

As part of our efforts to foster the development of blockchain talent globally, we pair each of our interns up with an expert to mentor and guide them. Here are all the ways that the mentors involved with Hyperledger’s 2017 summer internship program made a difference, in the words of our interns.

    • “My mentor, Baohua Yang from IBM, helped me in the project to understand and contribute.” — Indirajith Vijai Ananth
    • “My mentor, Jiang Feihu from Huawei Technologies, is one of the most supportive mentors I’ve come across to work with. Right from my selection for the internship, he started mentoring me and strategizing everything, although it was still a month difference from the official beginning of the internship. He’s a good mentor who helped me at every single difficulty that struck my way.” — Nikhil Chawla
    • My mentor was Makoto Takemiya from Soramitsu, and his mentorship helped me understand how Hyperledger Iroha and similar projects worked. We had meetings every week where progress on projects would be presented and where I would ask questions regarding details on Hyperledger Iroha and what the best way of achieving certain tasks would be. Makoto is a very skilled developer and he guided my research and development process to make sure everything was on track.” — Ezequiel Gomez
    • My mentor was László Gönczy from the Budapest University of Technology and Economics (BME), and Quanopt Ltd. His profound knowledge in business process modeling was a continuous source of guidance and support for my work. Firstly, he helped me to select of the BPMN elements to be implemented in the experimental prototype. The BPMN has an extremely large variety of notions in its metamodel (the standard being hundreds of pages long), but the important elements commonly used in the industry form only a smaller subset. Secondly, he helped to refine my approach by providing common, yet complex use cases/sample models. The expert guidance of my mentor played a significant part in successfully completing the project. Our work enjoyed a huge benefit of the professional advices of Imre Kocsis (BME).” — Attila Klenik

Thank you to all of Hyperledger’s mentors for fostering new blockchain talent and ensuring a successful 2017 summer internship program!

Meet the TSC: Arnaud Le Hors, IBM

By | Blog, Hyperledger Burrow, Hyperledger Fabric, Hyperledger Sawtooth

As promised, we’re kicking off a new blog series that focuses on the motivations and backgrounds of the individuals that make up Hyperledger’s Technical Steering Committee (TSC).

The TSC is a group of community-elected developers drawn from a pool of active participants and is a core element of Hyperledger’s Open Governance model. The model has worked for The Linux Foundation for 15+ years and therefore has been purposefully passed down to each open source project to offer an even playing field for all those involved – coming as close as possible to pure technical meritocracy as one can get. The TSC is responsible for all technical decisions – from which features to add, how to add them and when, among others.

With that background, let’s introduce Hyperledger TSC member, Arnaud Le Hors from IBM. Let’s see what he had to say about Hyperledger, his role in the TSC and the community!

Describe your current role, background and why you wanted to be a part of the Hyperledger TSC?

I’m Senior Technical Staff Member of Web & Blockchain Open Technologies at IBM. I’ve been working on open technologies for over 25 years, focusing on standards and open source development, both as a staff member of the X Consortium and W3C, and as a representative for IBM. I was editor of several key web specifications including HTML and DOM and was a pioneer of open source with the release of libXpm in 1990. I participated in several prominent open source projects including the X Window System and Xerces, the Apache XML parser. I currently am the main representative for IBM at W3C, an elected member of the Hyperledger Technical Steering Committee, and a contributor to Hyperledger Fabric.

My main goal is for Hyperledger to not merely be successful technically but be successful as a true Open Source project with an active, vibrant, and diverse community. There are too many projects out there that claim to be open source but fail to have an open governance. In my role on the TSC I will continue to strive to make this community truly open.

Arnaud Le Hors, Senior Technical Staff Member of Web & Blockchain Open Technologies at IBM

How are you or your company currently using Hyperledger technologies or how do you plan to?

IBM Blockchain offering is based on Hyperledger Fabric. After a period of development of proof of concepts we’ve now entered a phase in which we see more and more projects going into production. Some of these like Everledger and Maersk have been highly publicized already with the tracking of diamonds and shipping containers respectively. What I find interesting is that these projects show how broadly applicable blockchain technology really is. This goes way beyond cryptocurrencies.

What are the benefits of Hyperledger’s open governance model?

The power of Open Source is to make it possible for people with different backgrounds and skills to come together and work collaboratively to everybody’s benefit. Everyone gets more out of the project than they individually contribute. This model however only reaches its full potential with an open governance where all contributors are treated equally and have a say in the direction of the project. Without open governance, developers are merely treated as cheap resources willing to give their time and IP without any say as to where the project goes. Sadly, many projects typically led by big corporations do function like that. As I said earlier, it is my goal for Hyperledger to be truly open and part of my role at IBM has been to help our development team to switch from a closed development environment to open source. This doesn’t just happen. One needs to understand what it takes and apply themselves to it.

What’s the most important technical milestone for Hyperledger to reach by the end of 2017?

We’ve already seen the release of Hyperledger Fabric 1.0 earlier this year, Hyperledger Sawtooth and Hyperledger Iroha are working towards their own 1.0 release. I think it would be a great achievement to see those three projects, which were the first to start within Hyperledger, reach that major milestone by the end of the year.

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

Blockchain is a new technology. In many respects everybody’s still learning so it is a great time to get started. As more and more companies launch projects leveraging blockchain they will be seeking developers with the needed skills. Those who already worked on developing these skills will become valuable resources. Because all of the Hyperledger technologies are open source there is no cost to getting started. It is merely a matter of being willing to invest your time. Practically speaking, I would advise people to start by familiarizing themselves with the different projects to get some general understanding of the characteristics of the different frameworks. They all include documentation and tutorials that are can be used to get started.

What’s the one thing you hope to accomplish by being a part of Hyperledger’s TSC?

As mentioned before, if there is one thing I hope to accomplish it is to continue driving the project towards being truly open, with not only code in open source but also with an open governance. For example, last year, I took a leading role in the development of the Incubation exit criteria. These are criteria the TSC uses to gauge whether a project is ready to move out of Incubation into Active status. The fact that the criteria we defined are focusing on the maturity of the project – how the project is run, how diverse the community is, etc – rather than the maturity of the software that is developed is a reflection of that goal.

What’s a missing feature or spec that you hope Hyperledger can add in the soon future?

As we see more and more projects reach their 1.0 release, I hope we get more cross pollination happening between projects. For instance, an effort was recently put into integrating Borrow – a permissioned Ethereum virtual machine – with Sawtooth. I hope we get to see more of that kind of efforts happening moving forward.

What’s the biggest struggle or challenge you see Hyperledger having to overcome?

As understanding of the different major components of a blockchain framework improves, with help from the Architecture Working Group, it would be great to be able to identify pieces that can be externalized and shared by the different frameworks rather than have every project host its own. This is however not an easy task and with each project focusing on advancing its own framework it is difficult to get resources allocated to this kind of cross project effort. Once all the projects become more mature it should be easier to find resources for this but it will be harder to make significant changes to frameworks that have already been deployed in production.

What use cases are you most excited about with Hyperledger and/or blockchain?

Voting. Blockchain provides a distributed, secure, and audit-able record that fits perfectly the need of voting processes. What is more important than protecting our democracies?

ABCs of Open Governance

By | Blog, Hyperledger Burrow, Hyperledger Cello, Hyperledger Chaintool, Hyperledger Composer, Hyperledger Explorer, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha, Hyperledger Sawtooth

Today, most people understand the concept of Open Source – certainly we expect most readers of this blog understand it. View the code, use the code, copy the code, change the code, and, depending on the license, contribute back changes or not.

What many people don’t get, and something we here at Hyperledger and The Linux Foundation pride ourselves on doing well, is Open Governance.

The Linux Foundation, and all of our 60+ open source projects, are not-for-profits building the greatest shared R&D investment in history. Open Governance is central to this promise.

Open Governance means that technical decisions -– which features to add, how to add them and when, among others – for a given Open Source project or projects are made by a group of community-elected developers drawn from a pool of active participants. It is as close to the ideal of pure technical meritocracy as one can get and we strive continuously to reach that ideal.

Hyperledger recently concluded the 2017-2018 Technical Steering Committee (TSC) election, and so we thought it an opportune time to explain the ABCs of Open Governance. Please note that this is one Open Governance implementation and clearly not the only way to do it, but rather one proven and effective way.

What does the Hyperledger TSC do?

The TSC charter spells out the group’s responsibilities.

The TL;DR is that the TSC is the ultimate authority on technical decisions. This includes which new projects are admitted to Hyperledger , which current projects graduate from Incubation to Active , and the rules by which each Hyperledger project will operate.

Participation in Hyperledger through becoming a Contributor and/or Maintainer is open to anyone.
Hyperledger Charter Section 4C

As a developer or maintainer, this translates into one thing: trust. You know how decisions will be made and the process by which people will be selected to make these decisions. Hyperledger is vendor-neutral and technical contributions are based on meritocracy. We will always remain immune to the commercial interests of any single company.

The TSC election process consists of three simple steps:

  1. Identification of eligible participants
  2. Nominations
  3. Voting

Who is really eligible to be on the TSC?

The charter spells out that the TSC voting members shall consist of eleven (11) elected Contributors or Maintainers chosen by the Active Contributors.

So, how do you determine an active contributor, you may ask? As part of the current election, every project maintainer and Working Group leader was asked to provide a list of all the people that have contributed to their work in the past year. In addition, a review of all code and other contributions was conducted.

This year, 424 active contributors were identified as eligible to participate in the TSC election process.

Bring It (your nomination that is)

The Linux Foundation maintains an expert staff with decades of combined experience managing the operations of large scale, Openly Governed Open Source projects.

For Hyperledger, the Sr. Program Manager Todd Benzies ensures the trains run on time.

Below is Todd’s email calling for TSC nominations:

This nominating process produced 32 candidates for the 11 TSC spots. These 32 come from 20 different organizations, across a spectrum of industries, from technology vendors to foundations to end users from a variety of industries. They include people who work at Hyperledger members and non-members and some are standing as individuals.

A policy whose importance is hard to overstate is that anyone elected to a seat on the TSC is elected as a person unbound to the company for which they presently work. Should any TSC member during their tenure leave an employer for another, this would have zero impact on their standing as member of the Hyperledger TSC.

Cast your vote

Here is Todd’s email sent to the same list announcing the nominees and opening voting.

The arrow highlights one of the things that we’ve learned along the way as a trick to the trade of running open governance well. The voting system has to be unquestionably secure and fair (something by now truly everyone can relate to…).

We use the Condorcet Internet Voting System to safeguard the privacy of this election and voting process. CIVS can only be accessed by authorized voters, who receive a unique URL tied to their email address. Voters rank a set of possible choices and individual voter rankings are combined into an anonymous overall ranking of the choices. One vote is allowed per IP address.

Results

This process yields a fairly and openly-elected technical decision making body pulled from the community that cares about Hyperledger. We know they care not because they said so, not because the company they work for has joined Hyperledger, but because they invested their time to make contributions to Hyperledger code bases. Or, as Hyperledger Executive Director Brian Behlendorf says, “it’s a do -ocracy.”

Blockchain-based digital identity: How Hyperledger is helping to turn hype into reality

By | Blog, Hyperledger Fabric

Guest post: Andre Boysen, Chief Identity Officer, SecureKey Technologies

Identity has never been easy, but it’s particularly tricky in the digital age. For too long we’ve been forced to use outdated processes to prove who we are when we’re trying to get things done. It shouldn’t take a half-day off work and a trip to a government office to renew a passport, or an entire evening to update a smartphone plan, yet we’re being forced to do so because companies need controls to prove we are who we say we are and the gold standard for doing this today is a counter visit.

Thanks to blockchain, that’s changing. Distributed ledger technology is giving us the opportunity to do what we haven’t been able to do so far – prove with greater certainty that you are you, to immediately access the services you want online, in person or on the phone. Utilizing this approach, we can develop a digital identity and attribute sharing network designed to allow consumers to use digital credentials they already have with organizations they already trust (like their banks), and verify their identity quickly to access services from trusted institutions (like telcos, government services, even sharing economy companies) instantly and with certainty. No more need to create another username and password combination that will be easily forgotten, or dedicate hours on end to perform a simple task, like updating a driver’s license, setting up a new phone or checking your credit score.

SecureKey changed consumer single-sign-on for the better when we introduced the concept of triple-blind authentication with SecureKey Concierge. The simple idea was that using a single credential could actually increase privacy, because none of the transaction participants got a complete picture of the user’s transaction. The bank does not see your online destination, the government does not see which bank you used or your account details and SecureKey does not know who you are. The challenge for us when we moved beyond accessing services to registering for new ones was how to implement the triple-blind model for identity information.

While it was technically possible to do this with public key infrastructure (PKI), there were some difficulties. For example, if the receiver had to check the signature on the data for verification, the blinding broke. A possible solution to this was the introduction of a key exchange that effectively blinded the receiver. However, this created a fourth factor in the transaction system, which increased complexity and made it much harder to trace a transaction in the event of a compromised account.

Enter blockchain. The advent of this technology adds some key capabilities and allows us to solve our service registration challenges.  Among its many benefits, blockchain  allows us to implement triple-blind attributes, data signing for service integrity and resiliency to mitigate against a single point of failure.

The benefit goes beyond the individual citizen to the businesses they choose to use. In an age where everything is hackable and millions of customer records are stolen or dumped online every month, organizations are realizing that one of their most toxic assets can often be customer records. Organizations that can confidently verify the identity of their customers quickly without the need to store that customer’s data on their own networks experience a twofold benefit: not only is there a real world cost savings for their IT infrastructure, but there is also a massively reduced risk of being financially accountable in the event that bad actors attempt to steal their customer data, namely because the data never needs to reside on their servers in the first place. This greatly reduces the risk of customer data becoming toxic and negatively impacting a company following a breach or leak – something we’re seeing become much more frequent each and every month.  

We’re still in the early days of blockchain, but through communities like Hyperledger Fabric, hosted by The Linux Foundation, we’re seeing how its applicability can be endless. From currency to identity and further afield, blockchain is moving quickly beyond the buzzword stage and becoming critical to the evolution of services in the digital age.  There is a lot of blockchain hype to be sure, but for identity blockchain is going to be really helpful.

Developer Showcase Series: Aram Barnett, Vergo

By | Blog, Hyperledger Composer, Hyperledger Fabric

Our Developer Showcase blog series serves to highlight the work and motivations of developers, users and researchers collaborating on Hyperledger’s incubated projects. Next up is Aram Barnett, Blockchain Engineer and Managing Partner at Vergo.

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

First, identify why you need blockchain. With all the hype surrounding the technology, it’s easy to think you can capitalize on the hype by sprinkling some blockchain into your app. Without a well-defined plan on how and why you are going to apply it, you are simply wasting your time and money.

Second, I want anyone interested in the technology to commit to learning about the details surrounding the progress blockchain has made rather than just the media hype that surrounds it. According to Gartner Hype Cycle, blockchain is at the peak of the technology hype cycle, and soon blockchain will be transitioning into the “trough of disillusion” where people outside of the development community will think that all of the promises of blockchain are not possible. However, unlike many new technologies on the hype cycle, blockchain will quickly escape the trough of disillusionment and grow exponentially when businesses realize the value of private ledgers. It’s is not easy but with enough dedication and a thorough understanding of the fundamentals, a developer can contribute to the blockchain community and create world changing applications. Third, get familiar Go and Javascript.

Hyperledger Composer, the tool that we use to rapidly build and test business networks, uses Javascript to enable the creation of business actions. Once you dive in the technology, be mindful of the difference between permissioned versus non-permissioned ledgers (a.k.a. public versus private blockchains, respectively) and what they offer. We will soon be releasing our own teaching resources for developers get up to speed on Hyperledger and the best practices on developing blockchain based business networks.

Aram Barnett, Blockchain Engineer and Managing Partner, Vergo

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

I first heard about blockchain when I purchased my first bitcoin in 2011. I was so infatuated with bitcoin I dedicated 3 years of my life to running an alternative asset management fund that exclusively traded cryptocurrencies, learning everything I could about bitcoin and blockchain. I always knew that the real value of bitcoin came from the blockchain and in 2015 I began focusing all of my efforts on developing smart contracts on ethereum and coming up with business use cases.

I am currently working on Vergo, a company I co-founded to create blockchain-based business networks for open source and enterprise use.We’re working to make existing corporations more efficient by cutting excess expense associated with business transactions. To further support this community, we are open-sourcing some of our business logic to help other developers learn about this unique technology. We believe that this technology will allow developers to create turnkey businesses in which open-source business logic is easily deployable. This will increase access to entrepreneurship around the globe and empower people to start their own businesses.

More importantly, we believe we have the ethical responsibility to help transition the world to this new era in a responsible manner in which participants understand the consequences of enhanced business network efficiency and automation. We strive to ride the new wave of technological innovation by giving equal attention to corporate efficiency and social well-being.

If you look at  the Gartner Hype Cycle, mentioned earlier, blockchain is at the peak of public hype about its potential. This new wave of technology is scary to some and at peak hype it can seem like anything is possible. I made the choice to ride the blockchain wave. Since I first got involved with bitcoin and subsequently blockchain in 2011, I knew that it would be a promising technology that needs to be developed and implemented globally. We are currently at peak hype, so public interest will decline in the next few years. However, the underlying technology will still be revolutionary and over time the corporate sector will realize how truly valuable it is to their networks.

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

The most interesting project to come out of is Hyperledger Fabric. We are excited about the progress of Fabric 1.0 and what it has to offer to large and medium enterprises. I met with the lead developers at the Hyperledger hackfest in Washington DC to learn more about Fabric and help contribute to the project. Vergo is very interested in this because we see the long-term impact that Fabric will have on how companies deploy blockchain solutions. We are very excited to be building applications and business logic on top of the Fabric ledger that these talented developers have built. We are currently discussing the possibility of cooperation between Vergo and some IBMers to display our business applications running on the IBM z mainframe. Another exciting application called Hyperledger Composer, the application we use to model, build, and test our business networks very quickly using their  business development language. After speaking with  Simon Stone, one of the maintainers of Hyperledger Composer, we are very excited for the future of Composer as a development tool and the services they plan to integrate into it.

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

Blockchain has the ability to solve a lot of problems. The ability to capture the nature of “businesses” and their “workers” and digitizing those relationships could lead to efficiency increases across almost every industry.

I think what I am most interested in, in regards to public-facing blockchain solutions, is the possibility of interoperability between chains and the assignment of an identity to every person. For instance, imagine from the very day you are born you were assigned a bank account, a verified identity and trackable health records all stored on a government ledger. From here, your financials, health records, and identity would be immutable and secure and would follow you over the course of your life. The interoperability between your identity and your financial records, for example, would verify you exist while not disclosing your personal data every time you make a transaction. By solving the problem of identity, many other possible solutions arise.

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

Let me answer your question with another question: Where do I not see it?

Blockchain-based business networks are inevitable. I think there will be varied solutions for individual businesses and sectors that provide accessible solutions to problems associated with the analysis of big data and efficiency of transactions. Blockchain will be easier to collect and analyze data, which will enhance our understanding of business practices and markets.

Additionally, I hope that turnkey businesses will emerge across the world using open source logic developed out of the Hyperledger framework. The ability to replicate businesses with extreme ease will increase access to opportunities for economically disadvantaged peoples. I hope that the pool of open source logic is such that it allows anyone with enough emotional intelligence and work-ethic to provide a valuable product to a customer even without understanding underlying business logic.

(7.31.17) CoinDesk: Japan’s Fujitsu to ‘Commercialize’ Hyperledger Fabric Software by Next Year

By | Hyperledger Fabric, News

The research arm of Japanese IT firm Fujitsu has unveiled new technology it developed for the Hyperledger Fabric blockchain project as part of a plan to commercialize the software by next spring.

Billed as a means to speed up the rate of transactions for high-performance uses, Fujitsu Laboratories said today that it has developed and tested new tools to speed up transactions with Fabric. The first production-read version of Fabric was launched by the Linux Foundation earlier this month, coming weeks after the publication of a release candidate.
