The Return of the Hyperledger Summer Internship Program

By | Blog, Hyperledger Composer, Hyperledger Fabric, Hyperledger Iroha

Calling all student developers: Summer 2018 is your time to get real-world experience in blockchain technologies through Hyperledger’s internship program. We’ve put together an extensive line-up of internship projects proposed and led by active blockchain developers looking to expand Hyperledger projects and the technical community by teaming with the next generation of engineers.

This is your chance for one-on-one mentorship from some of the leading technologists in the Hyperledger community, as well as to build your development portfolio of projects that will feed into the larger Hyperledger ecosystem. Did we mention that these internships include a stipend and the potential to participate in Hyperledger Global Forum in Basel, Switzerland, December 12-15th? And you can work from anywhere!

The application is now open and the deadline to apply is March 23. Read on for descriptions of just some of the projects planned for this summer.

“The Hyperledger Intern Program is a great opportunity for everyone: interns, mentors and the broader Hyperledger community. I had the privilege of seeing last summer’s interns do their readouts, and engage the Hyperledger community members in Lisbon, and was impressed with their work. The feedback was universally positive from all involved.” – Chris Ferris, Hyperledger TSC Chair

Algorithmic Dispute Resolution in Construction

Construction is the second largest global industrial sector. Litigation accounts for approximately 10% of the expenditure. The industry suffers from a dysfunctional relationship between the architects, project managers, consultants, developers, and clients. This is a phased project that will model the workflows of a major construction project, in partnership with a leading UK contractor/project management company. The aim is to identify all relevant material prior to the contract being signed, automating the discovery phase of litigation, machining the large data set down to a ‘hearing bundle’ and then assessing ‘needs and interests’ prior to an automated resolution process. This is the first phase of the project and will focus on identifying the workflows and relevant documents, files and other digital material and on assembling them in the blockchain where authentication can take place and a ‘hearing bundle’ prepared.

Extended Functionality/Support for EVM Smart Contracts and Tooling in Hyperledger Fabric

Hyperledger Burrow has created an EVM implementation that is being integrated into Fabric. In its initial phase, Hyperledger Fabric will support EVM bytecode smart contracts in a limited manner. Some of the features that need to be added include support for EVM smart contract events and extending support for the Ethereum API. This project will involve working with and understanding different blockchain platforms and being able to map their differing concepts.

Python Library for Hyperledger Iroha

Hyperledger Iroha is designed for simple creation and management of assets. This is a distributed ledger of transactions. Interns are expected to make a full fledged Python library for Iroha. Later, in the next stage, we want the intern to maintain the docs of Iroha. There are many missing docs on getting started and about the internal works of Iroha. We expect the student to complete the doc part along with dev work.

Hyperledger Identity WG On-boarding and Auth

The Hyperledger Identity WG intern will be mentored by members of the Identity WG / Hyperledger Indy Maintainers and accomplish two main tasks: learn and develop an iPython notebooks for onboarding new community members and a browser-based authentication app using decentralized identifiers in Hyperledger Indy. This bachelors-level internship has two core goals: experience and contribution.

    • Experience: The Identity WG Intern will create interoperable, open-source code that will educate new and existing Hyperledger community members. Creating an iPython notebook and code sample will be based on their own onboarding into Hyperledger and Indy, using what they have learned in the process and helping the community by identifying what would be more effective in a better onboarding experience. For browser-based authentication with DIDs, Interns will learn critical professional development skills, from working in GIT to understanding the structure of well-formed code, to developing their own tests and proper documentation best practices.
    • Contribution:Through developing both projects (iPython notebooks / code samples and browser-based authentication with DIDs), the Intern will be making an important contributions to future Hyperledger community members onboarding efforts, the Hyperledger Indy codebase and the entire decentralized identity ecosystem.

Hyperledger Composer Modeling Tools

The Hyperledger Composer modelling language is used by both Hyperledger Composer and the Accord Project, Cicero as an object-oriented data description (schema) language, based on a textual domain-specific language. The intern will be tasked with improving the tooling for the the Hyperledger Composer modelling language, including the ability to generate UML style diagrams and web-forms.

Read more details on the above projects and many more here. Then check out the requirements and application steps. Remember, applications are due by March 23, 2018.

Onward and Upward for Hyperledger in 2018

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

As 2017 comes to a close, it’s beneficial to look back and reflect on the progress we have made, and where we will see evolution and growth in the new year. This year, the world has acknowledged distributed ledgers and smart contracts as transformative technologies with tremendous potential to impact how business is conducted in many industries. Within  Hyperledger, the technology foundations have now been set. In the coming year, that will turn into more production software releases, real world implementations, and the first real business returns on our collective intellectual and financial investment.  

Below are a few observations from the year, milestones and thoughts on what will come in 2018.

Blockchain maturation and more production implementations

  • Companies large and small, IT vendors and end-user organizations, consortiums and NGOs, everyone took notice of Hyperledger in 2017 and made moves to get involved. This was evident in the ever increasing Hyperledger membership, which nearly doubled in size. We sold out of our Premier memberships at 21 total, adding eight new companies just this year including SAP, American Express, Daimler, Change Healthcare, NEC, Cisco, Tradeshift and Baidu. Hyperledger now has support from 197 organizations, and remains the fastest growing open source project ever hosted by The Linux Foundation. This has given Hyperledger a very solid footing financially, enabling us to double the resources we can apply towards building and supporting the community in 2018.
  • We have grown our Associate Member ranks to include organizations as diverse as Mercy Corps, the National Association of Realtors, the Illinois Blockchain Initiative, and the Monetary Authority of Singapore.  These relationships are key to extending Hyperledger’s reach into different sectors and environments.
  • Attesting to our focus on developing code suitable for enterprise use, this year saw the launch of the first production ready Hyperledger blockchain framework, Hyperledger Fabric 1.0. This was a true community effort pulling together contributions from more than 100 different developers and 30 different companies. As one result, we have 45 members listed in our Vendor Directory, providing products and services based on Hyperledger technology.
  • We have seen substantial uptick in POCs, pilots and production implementations of Hyperledger technologies, many of which are being tracked at the PoC Tracker on the Hyperledger website. Just a few examples of projects building in Hyperledger code include:
    • The Monetary Authority of Singapore’s Project Ubin, implementing an RTGS system;
    • the soon-to-be-production diamond supply chain tracking system implemented by Everledger, SAP and IBM;
    • and the Plastic Bank, a plastics recycling initiative.

In 2018, we will see:

  • more 1.0 milestones made next year by various Hyperledger projects;
  • more production deployments: for example, Change Healthcare, has announced an early 2018 go-live for their claims processing blockchain built on Hyperledger Fabric;
  • a growing Hyperledger staff and presence at events, creating more content, supporting a growing set of projects and working groups;
  • and more membership growth. We are reaching out to a broader set of industries than ever, and are deepening our relationships with our existing members.  

The fast expanding developer and end-user community will continue to grow

  • Demand for developers, and developer interest in Hyperledger, has exploded. We are now seeing sold-out Hyperledger meetups in dozens of cities, strong attendance at our semi-monthly HackFests held around the world, thousands of participants on our email and chat networks, non-stop requests for speakers at conferences, and of course more and more code flowing into our repositories.
  • We launched the first Hyperledger online training course this year: Blockchain for Business – An Introduction to Hyperledger Technologies. Currently, there are  44,966 total enrollments, and 1,074 learners have completed the course with a passing grade. We have an average of 2,500 new enrollments per week. The course is second only in growth to the original intro to Linux operating system course launched by The Linux Foundation. We have now launched a Training and Education Working Group to involve core maintainers and other volunteers in the development of additional courseware.
  • 150 people participated in the Hyperledger Member Summit in November in Singapore, representing 83 different member companies.  

In 2018, we will see:

  • the development of additional training courses and certification options;
  • more frequent and larger face to face developer gatherings;
  • and more developer activity across additional Hyperledger projects.

Integration, standards and interoperability will take center focus

In 2018, we will see:

  • The industry get a lot more serious about interoperability above the layer of the DLT, and looking for simple and open cross-blockchain approaches, leading them to Hyperledger Quilt and the rest of our community;
  • and our projects explore integration and interoperability with each other even further, allowing a greater number of options to be available to developers.

We’re proud of the work our vibrant and diverse community has accomplished this year. We have made great strides and could not be more thankful to everyone who has played a part in this success. It goes without saying the stakes can be even higher in open source, it’s a balance of creating a welcoming, collaborative environment and at the same time making sure everyone gets a say and all voices are heard. We strongly believe the open governance model that Hyperledger naturally inherited from The Linux Foundation has been a crucial part of the continued success of the project.

Finally, you can stay up to date with all Hyperledger news here or follow us on Twitter. We hold regular hackfests for Hyperledger, so be sure to check out the events page and join us for the next one. You can also plug into the Hyperledger Community at github, Rocket.Chat, the wiki or our mailing list.

Here’s to a successful 2018!

 

VIDEO: Hyperledger, A Greenhouse Incubator for Blockchain Projects

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

Hyperledger hosts and incubates multiple technology projects, all advancing business blockchain frameworks and modules through open source collaboration. Currently, Hyperledger hosts 6 open source frameworks and 3 open source blockchain tools.

To introduce the concept of blockchain technologies and the Hyperledger organization, we created an explainer video illustrating Hyperledger as a greenhouse incubator for these open source blockchain projects. Intended to serve as a starting point suitable for all audiences wanting to learn about Hyperledger and business blockchain technologies, we hope this 3-minute explainer video will shed light on the following:

1. A distributed ledger is a common system of record with no central authority.

A ledger contains a record of your transactions, along with other transactions in the network. Distributed ledgers are multi-party databases with no central trusted authority. Blockchains can be used to record promises, trades, transactions or simply items we never want to disappear.

2. It’s vitally important to know that your copy of the ledger is identical to everyone else’s

All businesses participating in a commercial ecosystem need a ledger to contain a record of transactions. As a result, across the global market there are ledgers that organizations and individuals alike must trust. Mirrored exactly across all nodes in a given network, distributed ledgers allow everyone in an ecosystem to keep a copy of the common system of record, free from discrepancies. Nothing can ever be erased or edited; parties can only add to the ledger.

3. Hyperledger provides the underlying open source software, on top of which anyone can set up blockchain apps and services to meet business needs.

Hyperledger is incubating and promoting enterprise grade, open source business blockchain technologies, including distributed ledgers, smart contract engines, client libraries, graphical interfaces, utility libraries, and sample applications. Built under technical governance and open collaboration, individual developers, service and solution providers, government associations, corporate members and end users alike are all invited to participate in the development and promotion of these thriving technologies.

4. Hyperledger is a global, cross-industry, collaborative open source consortium.

With 170+ member organizations working across industries and competitive lines, and 400+ code contributors, Hyperledger is the fastest growing consortium in the history of The Linux Foundation’s collaborative projects. Just like you see in this greenhouse, with the help of The Linux Foundation and Hyperledger’s open source approach, everyone does their part to ensure the success of the whole, nurturing these blockchain ecosystems for evolution, expansion and continued growth.

The most renowned leaders in finance, healthcare and supply chain across the globe trust Hyperledger to build their business blockchain technologies. Who will you trust with your trust network?

We encourage developers to join our efforts on Hyperledger via github, Rocket.Chat, the wiki or the mailing lists. You can also follow Hyperledger on Twitter or email us with any questions: info@hyperledger.org.

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!

Interning with Hyperledger: 4 Interns Share Their Experiences and Advice

By | Blog, Hyperledger Cello, Hyperledger Iroha, Hyperledger Sawtooth

Just recently, four talented individuals finished summer internships with Hyperledger. We’re proud to congratulate them on a job well done!

Here, they share details about their projects and advice for students considering an internship in open source software.

About the Projects

Nikhil Chawla from India, mentored by Jiang Feihu from Huawei Technologies, worked on deploying Hyperledger Fabric on Kubernetes using Hyperledger Cello. Nikhil’s approach was twofold. First, it involved manually running Hyperledger Fabric on Kubernetes. Second, it involved automating the deployment using Hyperledger Cello. Nikhil says, “There were a long trail of issues I got to address via this internship. But identifying the levels was a good idea and subdividing the tasks helped me a lot. Moreover, the community channels like Slack and Rocket.Chat were a huge help. I used a variety of measures that can be adapted to reach each sub-task and eventually, solving them optimally.”

Indirajith Vijai Ananth from Italy, mentored by Baohua Yang from IBM, worked on improving and implementing features in Hyperledger Cello. Indirajith says, “The approach can be categorised into three major steps. First, to learn basics and get acquainted to the technology and the domain. Then, to learn deeper by going through the code to understand where and what to work on. The last step was to get involved from writing code and reporting bugs. The outcome of my project was the implementation of a health check feature in Hyperledger Cello for Hyperledger Fabric v1.0 network. This involved restructuring and updating image downloading scripts for Hyperledger Fabric and the respective documentation.”

Ezequiel Gomez from Mexico, mentored by Makoto Takemiya from Soramitsu, worked on anonymous transactions in Hyperledger Iroha. Ezequiel says, “The approach was to first look at how projects that currently have the ability to issue anonymous transactions work. Given that there is a small number of projects that achieve this efficiently, we based our work on Zcash and their usage of zk-SNARKs. The next step was to fully understand the different parts in the Zcash protocol and how this could be implemented on top of the Hyperledger Iroha ledger. I became acquainted with the development community of Zcash Company which helped me understand the academic papers that motivated the project. Given that the core of the project was usage of different cryptographic protocols, most of my research was focused on things such as key establishment, digital signatures and zero knowledge proofs. Since one has to be very careful when working with cryptographic protocols, researching the specifics on each part of the protocol was necessary to avoid mistakes when implementing cryptographic primitives.”

The project depended on staying in sync with the team of developers working on Hyperledger Iroha. Ezequiel says, “The outcome of the project was a standalone service with the functionality needed to implement anonymous transactions into the Hyperledger Iroha distributed ledger. Given that v1.0 of Hyperledger Iroha is still under development, the team decided to have me work on the anonymous transaction part as a standalone service while the team implements an unspent transaction output (UTXO) transaction model into Hyperledger Iroha after v1.0 is released. Without a UTXO model anonymous transactions would not be possible, since the current account model has no way of hiding who the owner of the assets is. The standalone service is not yet finished, and some parts of this service will be developed depending on how the UTXO model gets implemented into Hyperledger Iroha but it currently has two contributors on GitHub working on finishing its components.”

Attila Klenik from Hungary, mentored by László Gönczy from Quanopt and Budapest University of Technology and Economics (BUTE), worked on contract-based business process execution. Attila says, “The goals of the project were 1) to evaluate whether Hyperledger Fabric smart contracts (chaincodes) can fulfill the roles of a business process execution engine, and 2) to develop a methodology for the (almost) automatic migration of business process models (BPM) to the Hyperledger Fabric framework. This approach will enable the merge of existing sophisticated methods in business process modeling with the sound basis of blockchain frameworks.”

The complete coverage of Business Model Process and Notation (BPMN) is still a future work but according to Attila’s expectations, it can follow the approach and technology developed. Attila says, “The core result of the project is a conceptual proof of concept of using BPMN for designing smart contracts. This complements evolving technologies like incorporating business rule systems into blockchain applications by using the Hyperledger Fabric for communication and synchronization purposes. The feasibility of the general approach is proven by a pilot transformation of core BPMN elements to chaincode frames and an ongoing activity targets the re-use of the code developed in traditional BPMN frameworks. The subset implemented is sufficiently rich to support the most common applications.”

Advice to Students Considering an Internship in Open Source Software

As you can see from the experiences above, summer internships in open source software are serious internships that come with the prize of greater knowledge, skills, and connections to the technical community.

If you, or someone you know, is planning to pursue an internship in open source software, here’s a collection of tips they can use from Hyperledger’s 2017 summer interns: Nikhil, Indirajith, Ezequiel, and Attila.

  1. Starting work on an open source project can be a little overwhelming. It’s easy to lose yourself in the details due to a desire to know everything. This is a good thing of course, but not right at the start. To get around this, use a top-down approach when exploring such a project. Focus on the parts you need to work on (or use), and treat everything else like a black box. Once you get familiar with the top, you may take a step toward the bottom.
  2. Don’t be afraid to jump into chat rooms with the project community and ask away! Open source project communities are eager to help new developers and work very hard to make sure future contributors have the resources necessary to understand the codebase. Reading white papers is a good first step before diving into the code. Large open source projects may seem intimidating at first because of their size, but after a higher-level understanding on how the project works, looking at its individual parts will become much easier!
  3. Another way to get started is by cloning the repository of the particular project of interest and start fixing the basic bugs. Slowly, progress can be made by submitting patches and test codes. Eventually, this leads to contributing to an open source project that is going to leave a mark of its own in this technology-driven world.
  4. Before contributing to open source, look at the guidelines for contributing. Going through each and every document is a must, without it you’ll definitely fall into trouble.
  5. There’s a huge variety of projects for all different genres in open source, so choosing the right project is must. Never follow the crowd.
  6. Don’t lose hope if you struggle at first. Soon, you can master open source!

There is plenty of work to be done in open source. Be sure to let the talented students in your life know about this exciting career path.

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.”
