Hyperledger Fabric in Action: Conflict-proofing tantalum mining in Rwanda

By | 网志, Hyperledger Fabric

The real-world impact of blockchain is growing quickly with the upswing of production systems bringing new approaches to complex problems. One such case: a supply chain solution powered by Hyperledger blockchain technology is providing critical traceability to tantalum mining in Rwanda. This mineral, widely used in the manufacturing of electronics and medical and dental devices and implants, is plentiful and a key to economic development in Rwanda. However, mining practices in nearby regions are muddying the supply chain, making some tantalum a potential “conflict mineral.” To protect against conflict concerns and practices and thus ensure investment and stability in Rwanda-sourced tantalum, the Rwandan Mining, Petroleum and Gas Board turned to a blockchain system to increase transparency in the mining supply chain.

Circulor, a U.K based startup, working with mining company, Power Resources Group (PRG), piloted a system built on Hyperledger Fabric that creates an immutable record of custody to trace Rwandan tantalum from the mine to the manufacturer.

We sat down with Circulor to get the details on rolling out this Hyperledger Fabric network and plans for future development. This case study is a great roadmap for others looking to out Hyperledger into action. You can read it here.

Hyperledger Global Forum: Takeaways from a local blockchain professional

By | 网志, Hyperledger Fabric

I’m very curious and I love to meet people from all over the world. I’m fascinated by new technologies, learning what can be done, seeing what has been done and realizing the potential.

Meeting like-minded, open people is the favorite way my team at 4eyes and I satisfy our curiosity. Learning from each other, sharing experiences and discussing problems and questions is the best way to achieve this.

Tangible results are sometimes difficult to see in software frameworks, and perhaps more so within the DLT/Blockchain space. However, they are very important to understanding the technology and its potential. So looking at projects in various stages from prototype to production is immensely helpful for us and, eventually, for our customers and partners.

With that in mind, we were excited to hear that the global Hyperledger community was getting together in Basel, about 15 minutes from our offices! While I already got an in-person impression of the Hyperledger Community at the Hackfest in Amsterdam and in my activities within the Special Interest Groups for the public sector, it was wonderful to have the whole Hyperledger Community as a guest in my hometown.

I’ve been to dozens of blockchain-related events this year with the Hyperledger Global Forum serving as the grand finale. In my opinion, it was by far the best experience as Hyperledger is the most inclusive, down-to-earth and also self-critical blockchain community. I remember Brian Behlendorf reminding people in a working group call of the importance of honest and transparent communication about Hyperledger as it’s crucial for the credibility and future development of Hyperledger. This spirit permeated the whole conference. While we know that Hyperledger has great frameworks and tools for a broad variety of real-life applications, as open-minded professionals we all realize that there is no one-size-fits-all holy grail kind of solution. This mindset leads to very constructive discussions about the different ways of solving a task.

To satisfy my curiosity, I attended a variety of workshops, especially for those Hyperledger frameworks that were still new to me. So, for example, I experienced Indy hands on in John Jordan’s workshop and learned to bring natural language legal contracts into the blockchain using Accord from Dan Selman. As sharing is a essential part of the learning experience, Waleed El Sayed and I talked about our experience developing blockchain-based projects using Fabric and Composer, which led to very interesting discussions with the audience and also during the rest of the conference. Apart from the inspiring keynotes ranging from consensus and application of blockchain in various industries to philosophy of trust, Global Forum was an opportunity to talk to the broad variety of companies showcasing their products and services.

In terms of my developer skills, the time I spent talking to Caroline Church, IBM’s Lead for Blockchain Tooling, was probably the most impactful. At Accenture’s Hack-For-Good hackathon towards the end of the Forum, Caroline showed us the new way of coding chaincode in Fabric 1.4 and, even more important, the Visual Code extension she created that allows for easy testing and debugging of chaincode. This is a huge step forward in terms of developing chaincode in Fabric. Caroline’s tools will immediately help my team and me and will increase 4eyes’ efficiency dramatically.

From my point of view as a consultant, I learned a lot from the presented use cases, such as the very interesting talk from Marco Alarcon and Andrés Falcone about the Short Sales Lending solution they’ve created at the Santiago Stock Exchange. I was also very impressed by David Berger’s very pragmatic solution to facilitating proof of existence for the legal industry.

As I love to spend time with people all over the world, I skipped one or the other presentation in favor for a in-depth conversations ranging from technical to conceptual during the forum and fun to philosophy during the delegates party at the fantastic Pantheon. This way I met amazing people from all over the world: Japan, France, USA, South Korea, Chile, Saudi Arabia, Canada, Switzerland, Russia, China and many more.

My experiences at the Hyperledger Global Forum helped me to assess the possibilities and the maturity of the framework and tools and inspired many new ideas, which in turn will help my team and me to provide better guidance and consultancy for clients and partners.

We are looking forward to the next opportunities to learn and share at upcoming Hyperledger events such as the Hackfest.

The whole 4eyes team and I would love to welcome the Hyperledger family back in Basel in 2019!


Developer showcase series: John Greenhow, Peloton Blockchain

By | 网志, Developer Showcase, Hyperledger Composer, Hyperledger Fabric

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is John Greenhow of Peloton Blockchain.

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

To anyone that wants to get started working on blockchain, my advice is to just start. As we set out, our team had to go through a headspace change similar to moving from assembly to object-oriented.

We picked a platform, picked a simple goal and ran through the installation and a test. More than once if necessary (I installed and setup Fabric twice). As soon as you physically can, look at the files on disk or in the database to see how they change – it will demystify things much more quickly.

We started off with Hyperledger Composer. This was a fantastic way in for us. It allowed us to model the business network we had envisioned and to write and test the necessary logic very quickly, all while going back to check bytes-on-disk to see how things worked under the hood.

My other piece of advice starts with an old saying, “when you’re holding a hammer, everything looks like a nail”. There will be use cases out there to which blockchain is not well suited as a solution, and that’s OK.  Spend time looking thinking about eco-systems and business networks and where the cost of a decentralized solution is really going to make a difference to everyone in the network.  It will pay off in the long run.

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

Peloton Blockchain has developed software and a network for the tokenisation, issuance, discovery, listing, secondary trading and redemption of financial instruments and non-financial assets – in a way that is compliant with regulatory jurisdictions around the world.   

We can offer efficiencies in primary markets, new distribution channels for issuers and a whole new class of products for exchanges. We have 1 patent pending with 2 further patents in the pipe. Exciting times!

We’ve developed 3 products:

  • Issuer/Arranger System – this SaaS supports the tokenisation of products and publishing of new tokens or securities to a blockchain network; no development or scripting is required for new securities.
  • Blockchain Network – based on Hyperledger Fabric, this is a private, secure and scalable network designed to provide unparalleled breadth of distribution to issuers and lead arrangers; chain-code manages compliance and the full security lifecycle – we’ve built RESTful APIs to facilitate connectivity into crypto-exchanges and secure “nodes” for deployment.
  • Exchange System – an exchange trading platform designed for primary and secondary market trading of tokens and securities; we don’t (and won’t!) run a market ourselves, but we do provide the software and expertise if it’s needed to setup secondary markets.

Blockchain in general, and specifically Hyperledger Fabric, provided the best platform upon which we could build. The ability to deploy software to many different organizations and yet retain a trusted view of a ledger of security transactions and ownership opens a utopian vision for many in the capital markets. Blockchain is simply the perfect tool for this job.

What project in Hyperledger are you working on? Any new developments to share? Can you sum up your experience with Hyperledger?

We initially started on Composer and then moved to Fabric as we moved towards a production deployment model. We were sorry to leave Composer behind as it has so many great features – the modeling language and API generation chief among them.

Moving to Fabric involved a re-write into Golang, and we were really surprised by just how much code was needed to port what had been a fairly small project in Composer. I don’t say this to denigrate Fabric but to accentuate the power of Composer.

Our focus now is building out a production network. As well as deploying nodes to participating market operators, issuers and arrangers, we are hosting several nodes around the world to form a reliable back-bone to the network. To do this, we’ve utilized the AWS Elastic Kubernetes Service (EKS) and this has been a powerful tool in ensuring scalability.

We’re also looking ahead to production operations, and building web services and management consoles to automate and coordinate everything from upgrades to onboarding new network participants.

What do you think is most important for Hyperledger to focus on in the next year?

There are several routes available by which Hyperledger can continue to lower barriers to entry for new teams and projects. These include:

  1. A move to commoditization – installation, configuration and operation of databases, message buses, caches and many other complex software packages is out-of-the-box today. Experience in the field will contribute to incremental releases that continually shorten the time taken to be productive.
  2. Best of breed flagship – rolling together the (stable) killer features of different Hyperledger projects into a commodity enterprise project could reduce the risk stemming from dependency upon a single project and provide a single point of entry into the Hyperledger world for teams focused on solutions rather than platform evaluation. An example might include Fabric support for Composer models (or perhaps better, Composer cross-compilation to Fabric-ready Golang) packaged with Cello features pre-configured for particular use-cases.

Ongoing community out-reach, profile pieces and education remain invaluable and the more the better!

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

What really fascinates me about blockchain is that it rarely seems to be the most efficient or low-cost solution available. I’ve had endless conversations with technologists who see a simple, centralized solution as faster…easier…cheaper!

From the perspective of a single organization, this is true. Where the technology comes into its own is in making whole eco-systems of organizations more effective. Blockchain isn’t growing the one slice, it’s growing the whole damn pie.

How successful blockchain projects (in terms of adoption) are seems to depend on the benefits brought to all participants, rather than to a central orchestrator. To the central orchestrator, data is the new oil. Is that still the case if everyone has a copy of that data?

Seen through this filter, there is an implication of more broadly available efficiencies to many industries. This can only be good for economic growth in both developed and high potential markets.

Our project at Peloton Blockchain focuses directly on this, building highly connected networks of issuers, arrangers and exchanges to the benefit of all.

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

Ultimately blockchain is an application infrastructure layer, much like an RDBMS or messaging bus.

While there is (quite rightly) a lot of research and energy going into blockchain today, the hope is that the layer will become commoditized and that the focus will shift to the solutions that this enables for business networks.

Hyperledger already has projects that are well on the way to making this a reality and we’re really excited to see this continue.

What is the best piece of developer advice you’ve ever received?

Test your code!

Introducing Hyperledger Fabric 1.4 LTS!

By | 网志, Hyperledger Fabric

The pace of blockchain development and deployment is accelerating. Fortunately, so too is the scale and maturity of the community and technology at the core of Hyperledger Fabric. With an eye towards the growing rollout of production Fabric networks, we are pleased to introduce Fabric v1.4 LTS, our first long term support release.

The Fabric developers have been working with network operators and application developers to deliver v1.4 with a focus on production operations and developer ease of use. Key new production-focused features of Fabric fall into four key buckets:

  • Serviceability and Operations: As more Hyperledger Fabric networks get deployed and enter a production state, serviceability and operational aspects are critical. Fabric v1.4 takes a giant leap forward with logging improvements, health checks, and operational metrics. Along with a focus on stability and fixes, Fabric v1.4 is the recommended release for production operations. Future fixes will be delivered on the v1.4.x stream, while new features are being developed in the v2.0 stream.
  • Improved programming model for developing applications: Writing decentralized applications has just gotten easier. Programming model improvements in the Node.js SDK and Node.js chaincode makes the development of decentralized applications more intuitive, allowing you to focus on your application logic. The existing npm packages are still available for use, while the new npm packages provide a layer of abstraction to improve developer productivity and ease of use. We have also provided a comprehensive business scenario and tutorial to get you started with the new developer experience.
  • Enhanced data privacy: Data and transaction confidentiality has been a key driver for Fabric development since v1.2. With this new release, we have added two new enhancements: 1) peers for organizations that are added to private data collections can now retrieve the private data for prior transactions to which they now are entitled, and 2) automatically enforce access control within chaincode based on the client organization collection membership without having to write specific chaincode logic.
  • Hand-on tutorials: Commercially focused training to help developers move up the Fabric learning curve quickly and efficiently to speed adoption and deployment.

Complete details of the new features can be found in the What’s New documentation and release notes.

Hyperledger Fabric’s First Long Term Support Release.

As noted, Hyperledger Fabric v1.4 LTS marks our first long term support release. This is a critically important development for those beginning to deploy Hyperledger Fabric solutions into production and is a reflection of the confidence that the Fabric maintainers have in this latest release.

Our policy to date has been to provide bug fix (patch) releases for our most recent major or minor release until the next major or minor release has been published. We plan to continue this policy for subsequent releases. However, for Hyperledger Fabric v1.4 LTS, the Fabric maintainers are pledging to provide bug fixes for a period of one year from the date of release (Jan 10). This will likely result in a series of patch releases (v1.4.1, v1.4.2, …), where multiple fixes are bundled into a patch release.

If you are running with Hyperledger Fabric v1.4 LTS, you can be assured that you will be able to safely upgrade to any of the subsequent patch releases. In the advent that there is need of some upgrade process to remedy a defect, we will provide that process with the patch release.

Developer showcase series: Arielle Telesmanic, Scroll

By | 网志, Developer Showcase, Hyperledger Composer, Hyperledger Fabric

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Arielle Telesmanic of Scroll.

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

Blockchain is quite different from its centralized information system’s counterparts. It is very important to understand the fundamentals of Blockchain Technology and design a Blockchain ecosystem that is both cost effective and efficient to provide the favorable conditions needed to support industry migration or a public user base depending on intended use. Before getting to carried away at the drawing board learn about smart contracts, consensus models, blockchain states and the nature of the peer to peer distribution of data within a blockchain system. Ask yourself, “Can this scale? Is this a better alternative to traditional systems? What information do I need to record and how is this information being distilled to the right participants?

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

Currently, I am working on the logistics and system design of three blockchain projects focused on ensuring data integrity in supply chains and streamlining data recovery in the advent of a data breach or leak. To complement the data recovery project, we are also developing a main net to strengthen the modularity and ease of use in migrating to a Blockchain. Our efforts include optimizing transaction speeds, side chain communication and a method to promote efficient change-management.

My interest in blockchain peaked as I noticed the advancements in quantum computing have been Signiant. Quantum computing’s ability to decrypt cryptosystems used in industry is concerning and there needs to be more development on quantum-resistant encryption and data verification/handling.

What project in Hyperledger are you working on? Any new developments to share? Can you sum up your experience with Hyperledger?

Currently, we are working with Hyperledger Fabric and Composer. Hyperledger’s framework uses chaincode which allows us to work with different states of the blockchain per transactions triggers by different applications. Out of the box, Hyperledger has promise in aiding the permissioned access to states of the ledger which is not typically supported in traditional Blockchain solutions. More information to follow on our integration efforts and contribution to the Hyperledger framework on Https://

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

Although Blockchain technology originated as a fintech solution, I am more interested in identity management and data quality assurance use cases (specifically data validity). The world is data-driven. Whether data is used to report manufacturing defects, drive patient care plans or execute a transaction that involves Personally Identifiable Information, it is of utmost importance that data is accurate.

All Are Welcome Here

By | 网志, Hyperledger Burrow, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha, Hyperledger Sawtooth

A Minneapolis coffee shop that has fueled or at least caffeinated a lot of Hyperledger commits.

One of the first things people learn when coming to Hyperledger is that Hyperledger isn’t, like it’s name may imply, a ledger. It is a collection of blockchain technology projects. When we started out it was clear almost immediately that a single project could not satisfy the broad range of uses nor explore enough creative and useful approaches to fit those needs. Having a portfolio of projects, though, enables us to have the variety of ideas and contributors to become a strong open source community. Back in January of 2016 Sawtooth and Fabric were both on the horizon followed shortly by Iroha, but we wouldn’t have predicted that we would have Hyperledger Burrow and Hyperledger Indy – two projects that bear no resemblance to each other. Burrow is a permissioned Ethereum-based platform and Indy is a distributed identity ledger. Burrow is written in Go, and Indy was created in Python and is porting to Rust.

Both of these platforms are interesting in their own rights, but Hyperledger is even more interesting for the combination of these projects with the others. Both Sawtooth and Fabric have already integrated with Burrow’s EVM. Now Hyperledger has a set of offerings that can simultaneously satisfy diverse requirements for smart contract language, permissioning, and consensus. Likewise Sawtooth and Indy have been working together at our last several hackfests. The results of that may unlock new use cases and deployment architectures for distributed identity. So it’s not that our multiplicity of projects has given us strength through numbers, but rather strength through diversity.

Hyperledger Hackfest – December 2017 at The Underground Lisboa

The hackfests that we mentioned are one of the rare times that we get together face to face. Most of our collaboration is over mail list, chat, and pull-requests. When we do get together though it’s always in a new city with new faces. One of our most recent projects was hatched inside one of those buses. It wasn’t the most ergonomic meeting I’ve ever had but there was room for everyone on that bus.

Hyperledger Hackfest in Chicago

Our hackfest in Chicago was in a lot more conventional surroundings (still a very cool shared creative space .. lots of lab equipment and benches out of view on the other side of the wall to the right). Looking back at this photo is fun for me. I can see a lot of separate conversations happening at each table… people sharing different ideas, helping ramp new contributors, working on advancing new concepts with existing contributors. I can see a lot of similarity but also a little variety. It’s a busy room but there’s still open chairs and room for more variety.

Our next hackfest won’t be until March 2019 (Hyperledger is hosting Hyperledger Global Forum in December in Basel though). The March hackfest will be somewhere in Asia – location to be settled soon. The dates and locations of the other 2019 hackfests aren’t set yet. I don’t know where they will be specifically, but I do know that there will be a seat available and you will be welcome there.

These face to face meetings really are more the exception than the rule at Hyperledger. There are now more than 780 contributors spread all across the globe. 165 of those were just in the last few months. That means that every day we have a new person contributing to Hyperledger. Most of our engagement is through the development process. People contribute bug fixes, write new documentation, develop new features, file bugs, etc. If you’ve never contributed open source code before getting started might be intimidating. We don’t want it to be, though. There are a number of resources to help you get started. You can watch this quick video from Community Architect, Tracy Kuhrt. There’s documentation for each project, mail lists, a chat server, working groups, and some of the projects even host weekly phone calls to help new developers get engaged. Everyone in Hyperledger abides by a Code of Conduct so you can feel comfortable knowing that when you join any of those forums you will be treated respectfully. Anyone who wants to get involved can regardless of “physical appearance, race, ethnic origin, genetic differences, national or social origin, name, religion, gender, sexual orientation, family or health situation, pregnancy, disability, age, education, wealth, domicile, political view, morals, employment, or union activity.” We know that to get the best ideas, best code, best user experience we need your involvement.
