Meet the Hyperledger Interns!

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

Back in March we announced Hyperledger’s inaugural summer internship program. We put together several internship projects that span across our incubated projects (Hyperledger Cello, Hyperledger Iroha, Hyperledger Fabric and Hyperledger Sawtooth) proposed by active developers in the technical community.

Today, we’d like to introduce each intern, provide info on what they will be working on and get to know them a bit better. We asked each intern a few questions like what issue or problem they hope blockchain can solve and where they hope to see Hyperledger and/or blockchain in five years.

Let’s see what they had to say!

Hyperledger Intern Project: Preserving Privacy with Hyperledger Sawtooth

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

Bitcoin and blockchain technologies are totally dynamic and mesmerising areas of today’s technology driven world. Nothing else I’ve encountered in my education so far has excited me as much as blockchain or its related fields.

We are aware that bank institutions are still vulnerable to tried and trusted methods of sophisticated cybercrime. I really hope blockchain technologies when applied to the areas of crime and cyber-theft will ease the process for cyber crime officials to a very great extent. Blockchain which is a distributed ledger system when applied to the banking systems worldwide could deliver much better cybersecurity. Eventually, cyber-theft will be erased from the lists of crimes and online transactions will be immune from malicious participants. I strongly believe that these concepts will leave an imprint of dynamic transformation and legacy of its own on mankind.

2. Where do you hope to see Hyperledger and/or blockchain in five years?

It is true that the Hyperledger community is one of the most renowned open source projects in the world and it has exemplary researchers and developers working hard everyday to build and engineer systems that would stand the test of time. Five years down the line, I believe there will be more efficient solutions for the present day difficulties in blockchain which includes scalability issues, instant payments, low cost for micropayments and many more. I envision that the Hyperledger community along with its blockchain projects will act as a ground for the future’s globalization and economic factors. It will revolutionize the social and technological trends to a great extent.

Hyperledger Intern Project: Contract-Based Business Process Execution

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

Blockchain (and related frameworks, like Hyperledger Fabric) can serve as a firm foundation for critical applications in nearly all domains. Being a distributed, highly available, synchronization medium, developers can satisfy many requirements of critical systems using a single middleware, not to mention the additional security provided by blockchain.

2. Where do you hope to see Hyperledger and/or blockchain in five years?

In my honest opinion, in five years Hyperledger Fabric and blockchain will be just as supported by Business Process Modeling as traditional technologies nowadays. Mature toolchains will support the high-level design of blockchain-based systems. Technically and legally certified domain specific templates for smart contracts and pattern libraries for process design will elevate the trust at the technical level to that of the business. Furthermore, “blockchainification” i.e. using the Blockchain technology as a substitute for sequential inter party communication in consolidating and re engineering existing applications will be as common, as it was/is with the cloud. I believe blockchain will be a dominant technology, especially in the business process domain.

Hyperledger Intern Project: Anonymous Transactions in Hyperledger Iroha

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

Growing up in Latin America where financial institutions and governments are known to be very corrupt, the transparency of blockchains immediately caught my eye. Every year the amount of money sent to Mexico in the form of remittances increases, reaching an all-time high of 26,987 million dollars in 2016. As money flows in, a lot of this money is being kept by intermediary financial institutions or service providers that keep a percentage of this money and take a long time processing these payments. Remittances rank third in the sources of foreign exchange coming into Mexico, and around 43% of the 26,970 million dollars sent every year is being sent through intermediaries other than banks. These intermediaries charge workers 3-4% of the money being sent back to Mexico, but since the exchange rate from USD to MXN Pesos must also be taken into account, the families are only receiving around 83% of the money initially sent. Given that the monthly average transfer is around $300USD, a 17% increase would give the average receiving family $50 extra dollars every month. I hope that blockchain solutions can lower the transaction fees so that the Mexican workers are better rewarded for the sacrifices of being an immigrant. Given that blockchain transactions require no intermediary and have transaction fees much lower than 17% of the money being transferred they are already fit to solve this problem. However, we need to create blockchain solutions that make this technology more accessible to the average person.

2. Where do you hope to see Hyperledger and/or blockchain in five years?

I hope to see Blockchain providing businesses new solutions, allowing them to incorporate new business models and businesses trusting this new technology when searching for new solutions. Hyperledger provides businesses with properly architected blockchain and distributed ledger solutions, which can be implemented into incorporate new business models and solutions that would make industries more efficient. As more companies join Hyperledger, the amount of developers actively contributing to Hyperledger will grow as well. Within the next five years the distributed ledgers built by Hyperledger projects will be used to provide businesses with new solutions and opportunities, and the expanding community of developers will work hand in hand with business leaders to make sure there is a codebase that can fit their needs. A recent report on the current state of blockchains done by McKinsey found more than 60 use cases for blockchains after surveying 200 companies from different industries, and predict that based on the current rate of evolution, blockchain solutions will reach their full potential in the next 5 years. McKinsey identified seven use cases for blockchains which could generate 80-100 billion dollars in impact. Given the amount of innovation that blockchains will bring to the table in business solutions, I am excited to be part of this revolution with the future leaders of blockchain solutions.

Hyperledger Intern Project: Design and Implement Blockchain Clustering Platform for Hyperledger

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

Blockchain can provide open standard distributed ledger technology, which will provide more open and provisioned/controlled database of moving/transferring objects. One should not need to keep a separate record of objects and their state. Stakeholders can have their relative info at any stage of a transaction or lifecycle of an object or asset.

It is also more secure so, each stakeholder can be able to keep a record for them and contribute to the distributed structure to strengthen it.

2. Where do you hope to see Hyperledger and/or blockchain in five years?

In five years down the line, I think blockchain will be the backbone network of several mobile applications, the core of supply chain industries, logistics and even will be a mandatory tool or technological solution of several governmental records keeping departments. With the help of Hyperledger, anyone can have their own blockchain which can be tweaked to custom built to address one’s own problem.

Hyperledger Intern Project: Deploy Fabric on Kubernetes Using Hyperledger Cello

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

Blockchains are generally considered in technical grounds with Bitcoins (Cryptocurrency), where transaction of bitcoins is shared between the authorized parties and a ledger of those transactions is maintained among those authorized parties only. But, one of the diverse uses of blockchain I think is in healthcare where a patient has the freedom to share is medical history and other medication details, with the doctors he would want to share everything. Now, consider a scenario where a patient is being treated by multiple doctors at the same time, then, how easy it will be for the doctors to check the medical history in form of transactions of the patient. And suppose if one doctor makes an addition to his medication then it will be automatically updated in the ledger of other authorised doctors as well, and accordingly he can also make changes if needed. This is one of the significant aspect of blockchains (Hyperledger), as modernization is affecting the life force of humans, so it should be made as easy as possible for the humans to maintain their health in a modern era. Apparently, on the same concept of “Healthcare”, I along with some colleagues initiated a project named “Medcare” which was focused on a centralized system for maintaining patient’s health record and patient would authorize the doctors of his choice to have a look on his/her medical records. Unfortunately, we couldn’t give it a push due to lack of resources and time, but I assume blockchains can make it happen in a resourceful way.

2. Where do you hope to see Hyperledger and/or blockchain in five years?

Blockchain is a growing technology which has the potential to affect industries like, Finance, Healthcare, Software Testing and many more. Blockchains can be used to eliminate the need of 3rd-party ledger which is currently a part of online transaction system, like, while using Paytm for mobile recharge, a 3rd party ledger is being maintained by Paytm itself for your transaction, although the transaction occurred between you and your connection provider (Airtel,Vodafone etc.). I think ideally these whole transactions must be maintained between two parties only because 3rd party ledger are a kind of vulnerability which might cause a breach in security. In Healthcare , Blockchains can bring a whole new world which is a tightly coupled secure network, where privacy of patient records can be maintained easily and at the same time it is easily accessible from anywhere, anytime, if the person has the access using a signed digital contract or something like this. In software testing, It can help to solve some unsolvable problems such as Byzantine  fault  tolerance , Two Generals Problem and so on which are currently unsolvable with a proof. To understand this better, assume a situation, where a distributed database is being maintained using blockchains, if one transaction is occurred in these two connected nodes , and one of them fails and crashes down, then, the other connected node can help us to rectify the problem and can help to avoid this situation to occur in future. Now, as the time will pass, certain new areas will also be discovered where blockchain would act as a elixir and Hyperledger being a widely renowned project which aims to develop resourceful blockchain network. It will be the only best option and Hyperledger will be equipped with all possible working technologies of that time. For example, currently it is being added with “Kubernetes Support for Fabric”.

Please help us in welcoming all our interns! It is our hope that they continue to be valued contributors in the Hyperledger community well after their summer internships. You might even want to join them working on the Hyperledger projects. You can plug into the Hyperledger community at github, Rocket.Chat the wiki or our mailing list.

Consensus 2017 is a Wrap!

By | Events, Finance, Healthcare, Hyperledger Burrow, Hyperledger Cello, Hyperledger Composer, Hyperledger Explorer, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha, Hyperledger Sawtooth

The Hyperledger team (and 40 of our members!) spent a good amount of time in New York for CoinDesk’s annual Consensus conference last week. It was a great event with tons of excitement and enthusiasm around blockchain and its many applications. Attendees were from all walks of life – from developers to architects to financial services professionals to healthcare specialists to investors – all trying to better understand the best and most practical use cases of the technology.
The event kicked off the weekend before with the Building Blocks Hackathon at 30 Rockefeller where many of the world’s top blockchain developers vied to build the next killer smart contract app. Participants could build on top of any blockchain protocol: bitcoin, Ethereum, Hyperledger or otherwise. And through various sponsor challenges, they were encouraged to leverage the software and support made available by our world-class mentors in order to deliver projects.

Hyperledger was a sponsor of the event. The Hashed Health development team ended up winning the Hyperledger challenge, which was to create a game using any of the Hyperledger frameworks

(Winning team of the Hyperledger hackathon challenge and Hyperledger Executive Director, Brian Behlendorf)

Jonathan Levi, an active Hyperledger community member and the founder of HACERA, won 2 hackathon challenges using Hyperledger technology. They won the Enterprise Ethereum Alliance challenge and they were one of the winners of the Microsoft challenge. They called their solution Dutchess – a secure decentralized Chess on the blockchain that allows players to use ETH to pay for an unfair advantage in a sealed-bid Dutch auction. The entry highlighted Jonathan’s and HACERA’s approach of integrating multiple permissioned & public chains.

Dutchess incorporated:

  • Public Ethereum accounts used to transfer money to a sealed-bid Dutch auction
  • Confidential transactions using Solidity on Quorum, deployed on Microsoft Azure
  • A permissioned and public identity chain (Sovrin) for registering identity tokens
  • Hyperledger Indy for implementing secure verifiable claims
  • Hyperledger Sawtooth for transaction processing and validation

The result was a mini HACERA-like workflow that provided secure, auditable, privacy preserving, that prevents impersonation, relying on self-sovereign identity and offers a non-repudiation guarantee – with a playable fun game of Chess on a blockchain.

Early Monday, the Hyperledger team then set up shop on the 6th floor of the Marriott Marquis in Times Square. Crowds of attendees stopped by each day to learn more about the technology.  

 

At the booth several member companies gave demos on different Hyperledger projects including Hyperledger Fabric and Hyperledger Iroha. Cloudsoft demonstrated Deploying Hyperledger Fabric on Kubernetes with Cloudsoft AMP. IBM showed Connect a Cloud, connecting organizations together on Hyperledger Fabric using hosted cloud providers of choice. Soramitsu ran a KYC/user identity demo of Hyperledger Iroha/Android app and video, and Byacco, a local digital currency currently in use at University of Aizu in Fukushima, Japan. IntellectEU together with their customer Telindus (Proximus Group) explained streamlined asset transactions through reconciliation, matching and resolution among multiple parties.

Hyperledger also hosted a Roundtable on Monday on its distributed ledger technologies, Hyperledger Sawtooth and Hyperledger Iroha, each technology had end users speak to their different use cases. Kelly Olsen from Intel spoke to Sawtooth and his user, Pokitdok CTO, Ted Tanner weighed in on how they are utilizing Sawtooth in their healthcare blockchain solution. Makoto Takemiya, CEO, co-founder, Soramitsu discussed Hyperledger Iroha as a blockchain framework for mobile applications and Soichiro Takagi, from the Center for Global Communications (GLOCOM), International University of Japan shared his experience with the technology.

In addition to the robust line-up of Hyperledger activities in the main Consensus program and on the show floor, Hyperledger hosted a series of talks that ran all day Monday and Tuesday in the Hyperledger Mini Summit room. Attendees interested in how to best collaborate and get involved in the Hyperledger initiatives and learn where they can provide the most value had their bases covered in Monday’s “Meet the Hyperledger community” sessions. Speakers included the new technical staff, and diverse representation from the Technical Steering and Marketing committees, Governing Board, Identity Working Group and our fearless leader, Brian Behlendorf, Hyperledger’s executive director.

In Tuesday’s Hyperledger Mini Summit sessions, members dove a bit deeper into the impact of blockchain technologies on their businesses with field reports on how they are using Hyperledger to solve their business objectives. Attendees heard technical insights from Norbloc on the KYC process, IntellectEU together with their customer Telindus (Proximus Group) on streamlined asset transactions, as well as Cloudsoft on deploying and managing global blockchain networks.

Our members reinforced that blockchain is not only impacting business on a global scale, but also across industries through blockchain talks from Huawei on telecom, Daimler on the industrial enterprise, Deloitte on regulation, Energy Blockchain Labs on reversing China carbon emissions, and a panel of speakers from Accenture, BanQu and Leading Directions on blockchain for good applications.

Hyperledger hosted three different panels on Tuesday moderated by Executive Director, Brian Behlendorf and Security Maven, Dave Huseby. Those panels were “The Role of Open Source in Blockchain,” “Blockchain in the Wild, PoCs, Pilots & Deployments” and “Security, Privacy and the Enterprise Blockchain.”

(The Role of Open Source in Blockchain panelists: Dan Middleton, Intel, Casey Kuhlman, Monax, Makoto Takemiya, Soramitsu & Amber Baldet, J.P. Morgan)

 

(Blockchain in the Wild, PoCs, Pilots & Deployments panelists: Jesse Chenard, MonetaGo, Ashwin Kumar, Deutsche Boerse, Ram Komarraju, CLS Group, Corey Todaro, Hashed Health & David Treat, Accenture)

The panels were very well attended and there was great discussion on all three topics. It was most interesting that identity on the blockchain turned out to be the main topic of conversation during the security and privacy panel. And on that note, we’re excited with Hyperledger Indy just recently getting accepted into incubation under Hyperledger. Indy provides tools, libraries, and reusable components for providing digital identities rooted on blockchains.

(Security, Privacy and the Enterprise Blockchain panelists: Justin Newton, Netki, Drummond Reed, Sovrin Foundation, Jeff Garzik, Bloq & Astyanax Kanakakis, Norbloc)

We ended Consensus with a member party atop a NYC hotel rooftop. It was such a pleasure to see everyone and we are extremely grateful for all the support our community has provided around this event and overall. We’re looking forward to next year’s event – we hope that you can join us!

    • Removed and deprecated the old, superseded UI
  • Upgraded the Angular generator to generate Angular 4 applications.
  • Began work on being able to model, publish, and subscribe to business events.

Hyperledger Fabric

  • We agreed to a feature/code freeze at the Hackfest in DC, and selected co-release managers for the v1.0 release: Chris Ferris (IBM) and Jonathan Levi (Hacera).
  • At the hackfest, we also discussed and agreed on some changes to the development process proposed by Dave Huseby, which we will implement as a function of creating the release branch for v1.0.0-alpha2.
  • The TL;DR: of the proposal is that we will manage change through feature branches that will be merged into a development branch to undergo the full gauntlet of testing, and reverted if they still need work. Once the development branch has merged the set of features agreed for a release, the develop branch will be fast forward merged into the release branch (also the master branch), tested once more, and then published. The release/master branch which will always have the most recent stable release as the default on GitHub (as opposed to the head of development as is the case today).
  • Hyperledger Fabric added three new maintainers to help keep reviews up with the pace of change requests.
  • The rate of bug fixing has consistently outpaced reporting for the past 3 weeks, with in excess of 50 defects resolved per week.
  • The unit test coverage has seen steady improvement, now more than 70% (it had been 61%) with many key areas of the code at 100%. The integration test framework is taking shape and we expect to have regular testing (daily, performance/scale and long running) operational shortly.
  • Maintainers cut a v1.0.0-alpha2 release the week of May 8

Hyperledger’s Monthly Technical Update

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

As our incubated projects continue to mature, we’d like to update the community monthly on the progress we make. Below are updates on Blockchain Explorer, Fabric, Cello, Iroha and Sawtooth Lake during March.

Blockchain Explorer

  • Latest architecture document is now available on wiki.hyperledger.org
  • Created several Jira tickets required to complete the functionality
  • Completed the initial setup using the latest architecture as proposed in the architecture document

Fabric

  • We published the v1.0-alpha release [1,2,3] of Fabric, Fabric-ca and Fabric-sdk-node. Work now pivots towards testing, bug fixing and further hardening of the release. The maintainers will publish periodic releases as the code further stabilizes.
  • The TSC also approved incubation of a new Fabric SDK for Go. That project will be on-boarded shortly.
  • There is an active proposal to incubate the Fabric-Composer project, but the TSC needs another week of review and discussion. There seems to be interest beyond Fabric that warrants exploration.
  • Planning for a “connect-a-thon” across multiple cloud providers – one that demonstrates that Fabric can be deployed to multiple cloud platforms and integrated into a highly distributed and heterogeneous consortia network – is under way with a number of community members interested in contributing to that effort.

Hyperledger’s Monthly Technical Update

By | Blog, Hyperledger Cello, Hyperledger Chaintool, Hyperledger Explorer, Hyperledger Fabric, Hyperledger Iroha, Hyperledger Sawtooth

As our incubated projects continue to mature, we’d like to update the community monthly on the progress we make. Below are updates on Blockchain Explorer, Cello, Fabric, Sawtooth Lake and Iroha during February.

Blockchain Explorer

We completed the architecture review with the community and incorporated the feedback into the design document. The design document was posted on the “blockchain-explorer” channel on Rocket.Chat. We plan to upload this document to the Hyperledger wiki so that it is permanently available for anyone to review. We are continuing our work to make Explorer compatible with the Fabric 1.0 project.

Sawtooth Lake

New design updates were presented at the Hyperledger hackfest on Feb 1-2 and other Hyperledger forums. Parallel execution and new language support resounded well with the community. In the next month, we will begin work on new demonstration networks exhibiting some of the use cases prototyped using Sawtooth Lake.

Fabric

Fabric continues to press forward to wrapping up feature development for the 1.0 release. The team is preparing a version 1.0 preview initially, followed by an -alpha release by the end of February.

We’ve been bolstering our test frameworks with integration testing that had been developed by IBM for its offerings. We have also been taking a close look at improving documentation to make it more user and application-developer focused.

We had some interesting discussions with the Sawtooth team on integrating PoET into Fabric at the bi-monthly hackfest, which we hope to begin pursuing in the near term and we also continued working with the Sorimitsu team in aligning APIs.

Hyperledger Fabric played a prominent role in the largest blockchain hackathon to date, held in Groningen, Netherlands, Feb 10-12. 55 teams competed in five tracks and two of the five winning teams based their solution on Hyperledger Fabric. The other winning teams used Ethereum or Factom. Roughly half of the 55 teams were also using Hyperledger Fabric. It really was an exciting event and bodes well for the upcoming hackathon in Shanghai in March.

Cello

There are lots of discussions on the Rocket.Chat channel, mostly on documentations and deployment topics. Several Jira tasks were created as the feature roadmap, including refining documentation, supporting fabric 1.0 and supporting other blockchain platforms. We implemented the new dashboard configurations and refined the front-end code. Several deployment enhancement/patch sets are in the works to make Cello more stable.

Iroha

The API has been fixed and currently we are working on porting all the protobuf code to flatbuffers. There are several bugs/memory leaks with flatbuffers still, so we have been working with their project to fix these. We have also been working on getting flatbuffers working with grpc.

We are building a database for flatbuffers, iroha-ametsuchi. Anyone interested in working on it should take a look at the repository: https://github.com/hyperledger/iroha-ametsuchi

At the Hyperledger hackfest in San Francisco, we had an interesting discussion with IBM, where we outlined some ideas for creating inter-ledger transactions between Iroha and Fabric. If anyone in the community is interested in working on this together with us, please tell us on Rocket.Chat/gitter/github issue (https://github.com/hyperledger/iroha/issues/159).

That’s it for the updates! We encourage developers to join our efforts on these projects and help us shape the future of blockchain.
