Hyperledger 2018 Summer Interns Recap

By Blog, Hyperledger Burrow, Hyperledger Cello, Hyperledger Fabric, Hyperledger Iroha

It’s suddenly September and so it’s time to check in on our Hyperledger summer interns and mentors. Read on for more about five of the projects our interns tackled. We asked the interns about their summer with Hyperledger.

Here, their own words, are the goals, successes and lessons learned from each intern:

Ahmad Zafar (Project: Running Solidity Smart Contracts on Hyperledger Fabric or Vice Versa)

Project goals:

I was working on Running Solidity Smart Contracts on Hyperledger Fabric Project. The Solidity smart contracts are easy to write and are widely used by developers. The aim of this project was to help the developers to translate the publicly available Solidity smart contracts into readable and, hopefully, functionally equivalent Hyperledger Fabric contracts without writing the contracts from scratch. For Hyperledger Fabric, we chose Javascript language. Our goal was to translate 70-80% of the Solidity grammar/programs correctly into fabric smart contracts that are also human readable to make them easy to understand and change.

Successes:

I have successfully translated approximately 65-70% of solidity code to javascript code for Fabric smart contracts. Examples of language features include types, expressions, functions, events, function modifiers, structs, and single inheritance. Since Ethereum is a public blockchain with notions of Ether (Cryptocurrency) and Ether transfer, I had to provide functional equivalence in terms of Ether transfer on Fabric – (we ignore gas for now).

I have also translated 15 Solidity smart contracts examples to javascript code. These contract have been taken from different places. Some are from solidity documentation, and some are from github repositories, including the ERC20 token format which is used to create ICOs. These contracts were chosen with my mentor to cover a large number of Solidity features.

My translator will work on other contracts as well if the contract has 65-70% of the common components. My translated code and all examples that I have tested are placed on my github repository along with all the other content related to my project, including which components we have covered, how you can run this tool and results of my translated code.

Lessons learned:

For developing a translator from Solidity to Fabric, one has to have knowledge of compilers and has to learn both Solidity and chain code and both frameworks for testing code. Before starting this internship, I worked on compiler construction in my university project. The scope of that project was not big but making a translator for complete language was a massive task for me. Successfully completing that project boosted my skills in writing translator tools for different things. However, before starting this project, I had little knowledge about Ethereum and Hyperledger Fabric smart contracts. After this project, I have become skillful enough in writing both Ethereum and Fabric smart contracts. Other than languages, I have learned how to run contracts on both frameworks and their architecture. In short, I learned many things related to Ethereum and Hyperledger Fabric. This project will help me a lot to start development in blockchain, especially in Fabric and hopefully other Hyperledger frameworks.

A V Lakshmy (Project: Extended Support for EVM and and Tooling in Hyperledger Fabric)

Project goals:

My project involved the integration of Ethereum events into Hyperledger Fabric. The two key goals of the project were:

  • Implementation of event-related interfaces from Hyperledger Burrow to work with the event framework in Hyperledger Fabric
  • Modification of the JSON-RPC API functions in the fabproxy module to deal with events

Successes:

  • In the initial few weeks of my internship, I wrote some simple test cases for the chaincode evmscc.go. When my patch passed through the review process and finally got merged into the repository, I was elated
  • I also wrote code for an event manager module and modified the API functions in the fabproxy module. These pieces are still under review and will hopefully be merged before the September release.
  • This was my first experience with open-source development and in the exciting field of blockchain. I am thrilled that my work will eventually be included in the source code of a vast project like Fabric!

Lessons learned:

  • I got to study a new programming language, Golang.
  • I learned about Ethereum and Fabric and how to interact with these blockchain frameworks.
  • I got an exposure to version control systems like Git.
  • I grasped good software engineering principles, such as test-driven development.

I am very grateful to my mentors, Swetha Mam and Jay Sir , for patiently guiding me through this project. All in all, this project was an incredible learning experience for me!

Daniel McSheehy (Project: Hyperledger Fabric Chrome Extension)

Project goals:

The goals of my project was to build a Chrome extension that can connect to a Hyperledger Fabric network and provide an easy to use api for websites to send transactions.

Successes:

The Chrome Extension is operational. Through a simple api, a website can easily prompt the chrome extension to send transactions and query the ledger. The extension also requires confirmations from the user, preventing a website maliciously sending transactions.

Lessons learned:

Sometimes the “right” way to do something doesn’t work, so I had to come up with alternative solutions to get things working. Because my project is intended to make things easy for users, I also learned the importance of reaching out to others and receiving feedback.

Martin Martinez (Project: Simulating Hyperledger Networks with Shadow)

Project goals:

We had two key goals for the project:

  • Analyzing the current Shadow tool characteristics to find compatibility with Hyperledger networks.
  • Testing the Shadow tool with platforms such a Hyperledger Sawtooth, Hyperledger Fabric and Hyperledger Iroha.

Successes:

We successfully identified that Hyperledger Iroha is the most suited candidate to use the Shadow network simulation tool.

Lessons learned:

I learn more about the complexity and benefits of working in an open source community. Also, I feel grateful for the support of my mentor as well as the Hyperledger community members that I contacted through different channels such a Hyperledger chat.

Shuo Wang (Project: Design Effective Operational Platform for Blockchain Management)

Project goals:

My internship project focused on supporting dynamic blockchain configuration and integrating Fabric-CA module into Hyperledger Cello to make it more suitable for production environment. For beginners or in the testing environment, we often use an offline tool to generate all the cryptographic configuration artifacts statically. However, it is a centralized and unsafe way for a single user to generate all users’ identities in a real application scenario.

Successes:

I adopted Fabric-CA module and made the generation of cryptographic artifacts dynamic, automatic and decentralized. After users login into an operator dashboard, they could easily connect to a worker node and create the blockchain on it with quite simple configuration of the network type, size and roles in the blockchain. All the orderer nodes and peer nodes will register and enroll their identities from the CA server. Then users could login into a User-Dashboard to install and run chaincode in the blockchain with a newly generated user identity from the CA server.

I will continue to work in Hyperledger Cello Project after internship, and I plan to make the process of Cello workflow more dynamic so that each organization in the blockchain network could change their own settings more freely.

Currently, I am doing my master thesis at the Southern University of California and Tsinghua University. My research is focused on the blockchain consensus. Therefore, I am quite interested in seeing the Byzantine-fault-tolerant consensus used in the future version of Hyperledger Fabric.

Lessons learned:

During the internship, I enjoyed the culture of open source and learned some great tools for open source project development. The most important lesson I learned is to be timely in following up and keep in close touch with mentors and colleagues because people work collaboratively from all over the world. I really appreciate my mentor, Dr. Baohua Yang, and his kind help and guidance. He gave me many practical suggestions and shared deep insight of blockchain industry with me.

As a bonus, we asked for the intern’s take on what they’d like to see Hyperledger do in the future. Here are a couple of our favorite answers:

“I hope Hyperledger offers or organizes hackathons at universities. I think that it could be a great way to get students involved in blockchain and expose them to open source communities. I’m always amazed at the ideas people come up with at hackathons, and think that there could be projects and use cases that have never been thought of.” – Daniel McSheehy

“I hope that Hyperledger continues to give such amazing internship opportunities to students!” – A V Lakshmy

We would like to thank these interns for all their hard work and success. We would also like to recognize the mentors for all the time, effort and input they provided. Many of them went the extra mile and provided some their take on lessons learned, what they gained by being a mentor and advice for future interns as well. We will be posting their reactions and experiences with the program in another blog tomorrow – stay tuned! As always, you can keep up with what’s new with Hyperledger on Twitter or email us with any questions: info@hyperledger.org.

Meet the Hyperledger Summer 2018 Interns Part 1

By Blog, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha

Back in March, we announced the return of Hyperledger’s Summer Internship Program. This year, we have 12 interns, which is more than double what we had last year! We’re very proud of this program, as it offers students one-on-one mentorship from some of the leading technologists in our community, as well as it builds their development portfolio of projects that will feed into the larger Hyperledger ecosystem. The students applied to work on an extensive line-up of internship projects proposed by our community mentors.

Today, we’d like to introduce six of the 12 interns, provide information on what they will work on and help you get to know them a bit better. We asked each intern a few questions including:

  1. How did you first become interested in blockchain, and why are you excited to work on Hyperledger and your project in particular?
  2. How do you see blockchain technology evolving over the next five years?
  3. If there’s one or issue you hope blockchain can solve, what is it and why?

Let’s see what they had to say!

Hyperledger intern project: Algorithmic Dispute Resolution in Construction

  1. A few years ago, a good friend of mine told me that the next iteration of the internet was coming and it was going to be decentralized. At the time, we were both taking a class on internet protocols and had recently attended a lecture on the OSI model (a conceptual model for understanding the different layers for dot com internet protocols). A breakdown of the model revealed inefficiencies due to centralization (for example, the control of domain names), but we had been taught that these inefficiencies were necessary due to the economies of scale of technology companies. The possibility of a new system designed to solve these inefficiencies piqued my interest. After a few months of reading, I decided to fully commit myself to studying blockchain protocols. Since I went down the crypto rabbit hole, I have been impressed by the pace of progress in this space and the quality of output. After spending the past two semesters researching blockchain protocols at the University of Virginia, I was drawn to Hyperledger because of its emphasis on designing modular and interoperable blockchain solutions. Hyperledger’s architecture emphasizes a separation of the blockchain components, thereby enabling developers to build flexible blockchain applications that can easily interface between different consensus protocols, data storage modules, and communication patterns. For my project, I will construct an off-chain dispute resolution framework that leverages Hyperledger’s modular approach. I am especially excited to dive into Hyperledger’s architecture and explore the ways by which applications can optimize performance-security tradeoffs by incorporating a diverse set of tools/frameworks.
  2. Over the next 3-5 years, I expect the internet’s current structure to be overhauled and replaced by blockchain protocols. As brilliant teams around the world continue to collaborate and develop at an impressive pace, I expect that many of the problems that prevent the viability of blockchain solutions will be solved (e.g.., scalability, privacy, custody, UX). I am optimistic about the future of this space and excited to start contributing.
  3. Today, search engines like Google and social media giants like Facebook maintain an overwhelming amount of power and influence over the rest of the world. Even so, many people undervalue privacy as a basic human right, but I expect this to change over the next few years. There’s a Snowden quote that comes to mind: “Arguing that you don’t care about privacy because you have nothing to hide is like arguing that you don’t care about free speech because you have nothing to say.” I believe that advances in homomorphic encryption and multi-party computation coupled with blockchain innovation will provide liberation in the form of increased privacy.

Arijit Sen

Pursuing a Bachelor’s degree in Computer Science from the Apex Institute Of Technology in Bhubanshwar, India

Hyperledger intern project: Python Library for Hyperledger – Iroha

  1. I came across the concept of blockchain in my college. I found myself attracted to the whole concept of a decentralized system that is void of any 3rd party interference. I am really excited to work on Hyperledger since it addresses some critical business issues regarding blockchain. Also compared to other blockchain ecosystem platforms, Hyperledger had a smaller learning curve.
  2. Blockchain has already taken the technology world by storm. I am pretty sure that we will be seeing most of the current technology stacks shifted to blockchain. However, I am concerned regarding an uncontrolled blockchain system. Just imagine a scenario getting a perfect AI agent, powered to thrive over blockchain and letting him learn and work as much as he can. Maybe he will just develop himself as an unstoppable entity since there is no single server or database to hold him. Too much fiction? Well I doubt it. The growth on both AI and blockchain is exponential. I won’t be surprised if something like that happens.
  3. Blockchain can solve a lot of issues in the world. Just imagine a legal evidence system where all the legal documents and evidence can be put into a secure blockchain platform. Not even the wealthiest criminals could tamper with the evidence or forensic findings. It could power an unbiased law and order system. Or an unbiased voting system where no party can do any discrepancies during the election. Or it could secure payment transaction for overseas without any 3rd party interference. Blockchain opens up a thousand possibilities.

Hyperledger intern project: Hyperledger Identity WG Onboarding and Auth

  1. The first time I became interested in blockchain was couple of years ago when I heard about the decentralization concept and its implementations in Bitcoin and Ethereum. I am excited to work on the Hyperledger because of the following opportunities:
  • to work closely with community experts and developers to learn the open-source culture and skills
  • to advance knowledge in the distributed ledger design and one of its form, the blockchain
  • to get a teamwork experience with distributed, international colleagues

The project I chose is Hyperledger Indy, a distributed ledger purpose-built for decentralized identity. This project allows getting both practical and theoretical experience in blockchain development under the supervision of leading field experts. In particular:

  • to master skills in both Python and Rust programming languages, cryptography
  • to become familiar with the concept of Decentralized Identifiers (DID) and implement applications using it
  • to learn up-to-date software production techniques
  • to advance in creating and using tests as a professional developer
  • to get code reviews and advices on the best practices of documenting and structuring code

Throughout the internship, I will be making important contributions to the Hyperledger community, the Indy codebase, and the entire decentralized identity ecosystem. It will be an important step for me on becoming a professional software engineer.

2. I see blockchain technology becoming significantly used by public institutions (e.g., banks, universities). Also, I hope it will become more user-friendly and, as a result, more people will get involved in its development. Besides, some improvements should be made in blockchain-based systems (e.g., Bitcoin, Ethereum) with respect to its logs storage, which already takes a significant amount of memory.

3. One issue I hope blockchain can solve is a decentralized identity. Today’s main identification method requires users to login into every application (e.g., Facebook, Amazon) they interact with. Therefore, each user has dozens of login/password sets to remember (which also should be changed periodically). It is important to have a single and decentralized identity, as it will increase user’s security and user’s experience.

A V Lakshmy

Pursuing a Bachelor’s degree in Computer Science and Engineering at IIT Madras in India

Hyperledger intern project: Extended Support for EVM and and Tooling in Hyperledger Fabric

  1. I am an undergraduate student in the Department of Computer Science and Engineering at the Indian Institute of Technology Madras (IIT Madras), India. Being a Computer Science student, I like to keep learning about new technologies. I first learned about blockchains by reading about Bitcoin, and other blockchain platforms, in newspapers, magazines, and on the Internet. I was amazed at the way blockchains could utilize distributed ledgers to eliminate the need for trusting third-parties in transactions! More recently, my uncle told me about the Hyperledger Summer Internship Program. I viewed this as a great opportunity to work on a project relating to blockchain technology, the talk of the town these days! During this internship, I am going to be working on a small portion of the integration of EVM (Ethereum Virtual Machine) into Hyperledger Fabric. This project has really interested me because I will get to learn about two different blockchain platforms, Hyperledger Fabric and Ethereum, and understand their similarities and differences. Moreover, this is the first time I will be engaging in open source development, and I am pretty sure this will be a great learning experience for me!
  2. Blockchains have the potential to completely change the way businesses, governments and societies function. I envisage a future where money-related transactions will be carried out in real time using blockchains. Tracking the movement of goods in the supply chain will become completely transparent. Each person will have a unique digital ID on the blockchain, which can be used not only for authentication on a global scale, but also to keep personal information safe and secure. But, in order to live up to its potential, blockchain technology will have to deal with challenges such as scalability, regulations, and so on. To incorporate blockchain technology into their current legacy framework, companies will have to do a complete revamp,  which will obviously be very expensive. For widespread acceptance of blockchains, a change in mindset of the public will also be required. If we are able to come up with ways to deal with these problems, blockchains will surely revolutionise the world!
  3. In today’s world, there is a lot of corruption in business transactions. Bribing and under-the-table dealings have become very common. Many times, people who are supposed to receive money don’t actually receive it, as it is pocketed by some middle-man. Blockchains provide a distributed ledger to store information about transactions in a tamper-proof manner. So, blockchains can be incorporated into businesses, making all transactions completely transparent. Every transaction can be seen publicly, which will discourage people from taking bribes, or pocketing others’ money. And, wrongdoers cannot try to cover up their shady transactions by trying to change the contents of the ledger, as they will surely be caught by others on the blockchain during the verification process. Thus, I feel, blockchains may be an effective way to curb corruption!

Hyperledger Intern Project: Running Solidity Smart Contracts on Hyperledger Fabric or Vice Versa

  1. After completing my Bachelor degree in computer science, I started working in the industry for almost two years. But my future plan was something else. I wanted to do research in different fields of computer science. I explored different things, which are exclusively demanding related to my field. The specific field that attracts me a lot is blockchain. After discussing with fellow teachers in Information Technology University, I learned about the opportunity to be a Research Associate, working on blockchain technology. It was a great pleasure for me to work on my desired direction. Here I started my research on Hyperledger Fabric, in which I explore many things. My aim is to learn to write smart contracts in an efficient way, so that I can deploy applications on Hyperledger Fabric. The project that I selected enabled me to enhance my skills related to it.
  2. In my country, Pakistan, most of the people involved in the computer science field do not know about blockchain. Until a few months ago, most of the people considered Bitcoin as blockchain. Many think that blockchain is only used for cryptocurrencies. But the truth is, blockchain can deal with storing and transmitting information, automating the purchase process, improving transaction flow, securing the supply chain, etc. Nowadays people are well aware of blockchain through seminars conducted at universities and industry level. And many companies have started working on it. Furthermore, in my university, ITU, a lab is being set up only for blockchain research. 35 to 40 people will be hired including research associates, Phd Students and experts. Blockchain is providing enhanced transparency, greater scalability and better security. For these reasons, people are traversing to it to achieve various innovations to increase profits and strengthen relationships across the supplier. And in the next five years blockchain will be commonly known to IT people.
  3. Nowadays banks are using some middle organizations for getting services from other companies for scalability such as payments of utility bills, loading mobile accounts, transactions among cross banking, etc. For example, banks uses a middle organization for telecom services to recharge the mobile account. Blockchain can eradicate the middle organization from the banking system. We can use Hyperledger Fabric channels, and shared ledger and smart contracts for this purpose. This leads to a decrease in time, extra charges and improves traceability of transactions.

Hyperledger intern project: UTXO Transactions in Iroha

  1. I first heard about blockchain from my brother Sachin Mittal. It’s astonishing features like distributed, decentralised, shared, authenticated, auditable, immutable and many more fascinated me and drove me to understand the very depth of this technology. Learning more about Bitcoin and other cryptocurrencies, I got to learn its limited implementation in the financial exchange. But, with the advent of Ethereum, things changed. Smart contracts showed the pathway of automating and regulating industries on DLTs. But many restrictions such as the principle of hierarchy of any organization were compromised and every network started its own cryptocurrency just to fabricate itself with the name ‘blockchain’. The problem was solved by Hyperledger Iroha, which is a permissioned blockchain with prebuilt commands hence easy to incorporate into infrastructural projects requiring DLTs. My project allows me to understand this very innovative technology and to add a new feature, a UTXO based transaction model that is currently used by bitcoin
  2. We are witnessing the beginning of a new chapter in human history, just like when the internet came along and changed so many aspects to the way we used to live. Based on the current rate of evolution, I believe blockchain solutions could reach their full potential in the next five years. The maturity of blockchain has started to soar, its development is starting to have a material impact on every individual. The true nature of equality is here, which means of power is changing, thinking is changing. Blockchain and its development are starting to have a material impact on everyone’s life. Governments have already stated that they have much interest in blockchain technology and they want to learn more about its development for adapting it to their local financial systems. Unlike the dot-com bubble, I think blockchain technology is here to stay and it will be adopted by almost every field globally. The global leaders in government, finance, banking, IoT, supply chain, manufacturing, technology are acknowledging its potential.
  3. The issue I hope blockchain can solve is our centralized internet and social networks. People, without even blinking an eye, sign and agree to privacy policies that give the mainstream companies the power to use their data in any way they see fit. Privacy and security of individuals depend on their behavioural data which can be hacked (Experian) or misused (Cambridge Analytica). With blockchain, users will be able to choose whom to show their  content to and be able to set their own restrictions while determining how and where it gets distributed. They’ll also have full control of their private data. No more storing it on centralized servers and losing it when these servers go down or when their security gets breached.

We’re happy to welcome such a solid group of young people to the community and look forward to seeing all that they contribute. We hope you join them in the effort by contributing to Hyperledger projects. You can plug into the Hyperledger community at github, Rocket.Chat the wiki or our mailing list. As always, you can keep up with what’s new with Hyperledger on Twitter or email us with any questions: info@hyperledger.org.

Be sure to check back for the second post in this series that will highlight the other six interns we will have this summer!

12:15pm: B9lab – Someone needs to build it: closing the Hyperledger talent gap by Elias Haase, Founder

Every day, B9lab gets requests for Hyperledger Fabric developers, from concept-phase startups to major enterprises. However, as these requests grow, so does the need for thorough vetting and certification in the Hyperledger talent market. How do you know if the developers you are hiring are as good as they say they are? Come see this presentation to find out!

12:45pm: REMME – REMME WebAuth – passwordless authentication powered by blockchain by Alex Momot, CEO

REMME WebAuth is a first and one of the basic DApps in the REMME ecosystem. This demo will demonstrate how users (employees or clients) could log in into the browser service via REMME in one click. REMME is an access management solution that obsoletes passwords. For each device users generate certificates. Once it is installed on a device it enables one-click authentication on the service that has REMME integrated with. REMME WebAuth could be integrated with any service, from crypto exchange to big enterprises’ intranets or web services.

1:45: Altoros – Decentralization of P2P Securities Transfer Implemented on Hyperledger Fabric by Greg Skerry, Blockchain Solution Architect, Trainer

This presentation will cover details of a working blockchain project implemented for a National Settlements Depository Institution: decentralized platform for peer-to-peer securities transfer and keeping the records of securities owned by each holder. The solution developed on the Hyperledger Fabric framework keeps an immutable, auditable chain of records reflecting securities ownership transfers. This presentation will focus on the product functionality: how the platform works; how it can be adapted for transferring different types of assets or rights, incl. intangible assets.

In addition to these demos and presentations, several Hyperledger members including MedicalChain, Embleema and Change Healthcare will participate in the “State of Blockchain in Healthcare” panel at Consensus 3:10pm on May 15.

You can also join Hyperledger on the last evening of Consensus from 6-8pm at the Meetup: “The Hyperledger Greenhouse: Meet Developers Building Blockchain Frameworks” to get a chance to network and hear directly from developers of several Hyperledger frameworks! Tracy Kuhrt, Community Architect at Hyperledger, will provide an overview of the frameworks and tools that you can leverage for your enterprise blockchain solution. Then breakout sessions will give you the opportunity to have a deeper discussion to learn more about Hyperledger Fabric, Sawtooth (Seth), Indy and more. Please bring your burning questions about how to get started and participate in the Hyperledger community.

Dave Huseby, Hyperledger Security Maven

When I started as the Hyperledger Security Maven just over a year ago, I set out to make sure that Hyperledger’s community of contributors were doing everything possible to make good on the promise of better software and better security from the open source process. As of right now, we have in place a public bug tracker, continuous integration builds, core infrastructure initiative compliance, and a full responsible disclosure security bug policy and process. Today, I am happy to announce the next piece of our security process: the Hyperledger Bug Bounty.  

For the last six months we have been running a private bug bounty with HackerOne. Today we are opening up the Hyperledger Bug Bounty for public participation. Currently only Hyperledger Fabric is in the scope of the bounty program but we hope to add Hyperledger Sawtooth and other Hyperledger projects soon. HackerOne will continue to administer the bug bounty for us with close cooperation between their team and our community. We chose HackerOne because we think it is the best use of our resources and they share a similar commit to open source software as Hyperledger and The Linux Foundation.

At Hyperledger we have a broad base of committed developers and it is their professionalism that makes our security process solid and straightforward. When I first started, we already had in place our public bug tracking system and most teams had set up continuous integration build systems for monitoring build health. In the last year we formalized the process by which projects can move from development status to their first 1.0 release, including a number of security requirements.

The first security requirement is to meet the requirements of the Core Infrastructure Initiative (CII). The Core Infrastructure Initiative is a set of best practices for open source software security. Earning the CII badge requires open source projects to set up services and processes and key positions that all serve the goal of producing more secure and trustworthy software. At the time of this writing, Hyperledger Fabric, Sawtooth, Iroha, and Composer have all earned their CII badge.

The second security requirement is to nominate one to three members of a project’s community to participate on the Hyperledger security team. The Hyperledger security team manages and executes our policy of responsible disclosure of security bugs. Security bugs are confidentially reported to Hyperledger through security@hyperledger.org or by filing a security bug in our JIRA. It is the job of the volunteer security team to triage, respond to, fix, and disclose the security bugs that are reported. As of right now, the security team consists of 16 members from five of our project communities.

The third security requirement is for a project to undergo a security audit from an outside auditor to establish a baseline for the codebase. We hired the auditing firm Nettitude to do security audits of Hyperledger Fabric, Sawtooth, Iroha and Composer.  So far Hyperledger Fabric, Sawtooth and Iroha have been completed and are in various stages of resolution and publication. Currently only the Hyperledger Fabric security audit report has been fully resolved and published. The rest will be published soon.

Looking ahead into the future, I plan on getting more involved with the Software Package Data Exchange (SPDX) to see if we can use Hyperledger blockchain platforms to better track the provenance of open source software, including our own. I hope to one day use verifiable claims to automatically check for vulnerabilities in dependencies from our continuous integration build system. If open source software packages were to issue a verifiable claim stating that a specific version of their software has no known security vulnerabilities, then when one is reported, the claim can be revoked. The revocation of the claim could then function as an automatic signal to all users of that software that they need to update. Continuous integration systems could check the claims of all dependencies and stop the build if one or more are found to have vulnerabilities.  This represents the next generation of reproducible builds and would leverage blockchains for provenance tracking of software from construction all the way through deprecation.

Security is always an ongoing process of improvement. Thanks to the commitment and professionalism and general good cheer of the Hyperledger community, we have made great strides in the last year. Now with our public bug bounty, we hope to further make good on the open source promise and to deserve the trust our users have in us.

We encourage developers to join our efforts on the bug bounty program and also start contributing to Hyperledger projects.

(3.28.18) CoinDesk: Hyperledger Tech Heats Up Ahead of Software Debuts

By Hyperledger Burrow, Hyperledger Composer, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha, Hyperledger Sawtooth, News

Just six minutes.

That’s how long Hyperledger executive director Brian Behlendorf had to get former Chilean president Michelle Bachelet up to speed on blockchain. Spurred by a special request from the nation’s lawmakers, Behlendorf was one of multiple blockchain experts called to the country to talk about the merits of the technology and the ways in which it could modernize the copper-rich nation’s mining supply chain.

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 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 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 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 building 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.
