Welcome David Boswell, Hyperledger’s Director of Ecosystem

By | Blog

We’re thrilled to announce that the Hyperledger team is continuing to grow in 2018. Please join us in welcoming David Boswell as the Director of Ecosystem!

David is a community expert who has worked with Mozilla, Open Networking Foundation, NASA, Sun Microsystems, Nokia and more on their community strategies. Through these past experiences, he has expertise with both launching a new community as well as scaling existing communities.

Now let’s get into some questions to better understand David’s role, what he will be working on and his own aspirations for Hyperledger.

What got you interested in working on Hyperledger and blockchain?

I was fascinated by the ability of blockchain technology to build trust and accountability. In our world today there is a great need for building more trust and accountability so this feels like a very important effort to become a part of.

David Boswell, Director of Developer Ecosystems

What are your main goals now that you’re part of the Hyperledger team?

One of my main goals is to bring in my experience of what has worked (and not worked) in other open source communities.  When I got involved in an open source project for the first time in the late 1990s there was a lot of trial and error since no one knew what was going to be successful.  We’re really lucky now that there is a long history of building successful open source projects we can leverage and I want to take best practices and good ideas from other communities and apply them to the needs of the Hyperledger project.

What do you think is most important for Hyperledger to focus on in the next year in terms of developer traction and community growth?

Scaling a community is a big challenge and I want to make sure that the excitement and enthusiasm around Hyperledger is translated into a growing community that continues to work well for everyone.  A major challenge with growth is that processes and dynamics that worked well when the community was smaller can break down as the size of that community grows.  It can be hard to realize when it is time to change something that has worked well in the past or when to introduce new things to keep a community running well.  I saw this first hand as Mozilla went from a small project to a very large global community and I’m excited to share what I’ve learned about how to scale in an effective way.

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

A friend of mine who worked with volunteers at the Red Cross told me that the best way she knew to get people to participate was to ask for their help.  I’ve found this to be extremely powerful advice for open source communities.  There is a tendency to think that people will have ‘an itch to scratch’ and will show up and start working on things that they’re interested in.  That is true at times, but there are also many times when people  want to help but don’t know what to work on and letting them know where we need help and asking for their support can greatly increase the amount of participation within a community.

What do you like to do in your spare time?

After seeing the total solar eclipse in Wyoming last summer, I’ve become fascinated with those and am figuring out when to see another.  I might have to wait a few years for the next opportunity though, so in the meantime I enjoy reading, hiking, diving, seeing live music and exploring the interesting things that the Bay Area offers.

(2.2.18) CMSwire: How Hyperledger is Accelerating Blockchain for the Enterprise

By | News

For many, the term ‘blockchain’ is still shrouded in mystery — although the definition of blockchain and how it will impact business is simple enough to grasp. The problem is that when blockchain first emerged, it became (incorrectly) synonymous with the term cryptocurrency because it was helping to facilitate cryptocurrency transactions. However, while that is one use case for blockchain, but it’s potential spans much further across the world’s economic

(2.1.18) JAXenter: Making smart contracts safe with Hyperledger Sawtooth

By | Hyperledger Sawtooth, News

JAXenter: Hyperledger Sawtooth 1.0 has just been released. What’s the star feature of this milestone?

Dan Middleton: Since Hyperledger focuses on enterprise-grade blockchain technologies and is recognized as one of the leaders (rather than focusing on cryptocurrency), this is a major milestone for the Hyperledger technical community. Sawtooth has a number of differentiating features you’ll see listed below. The distinction for a 1.0 release, though, is not features but maturity. See #6 for a fuller description of what that means.

In a nutshell, though it means the code has been rigorously tested and reviewed, the platform has been field tested, and you can build your apps on the API without fear of it changing and breaking your apps — an issue that plagued many companies starting out with other blockchains.

(1.31.18) Enterprise Times: Sawtooth 1.0 to speed up blockchain development

By | Hyperledger Sawtooth, News

The Hyperledger Sawtooth 1.0 modular platform for building, deploying and running distributed ledgers has been released. This is the second of the Linux Foundation Hyperledger projects to reach this milestone. Last year the Hyperledger Fabric also hit 1.0 and is expected to go to 1.1 in the next few months. This year should also see at least one more of the nine currency projects hit the 1.0 milestone.

Developer Showcase Series: Hrishikesh Nashikkar, Broadridge

By | Blog, Hyperledger Fabric

We return to our Developer Showcase blog series, which serves to highlight the work and motivations of developers, users and researchers collaborating on Hyperledger’s incubated projects. Next up is Hrishikesh Nashikkar, blockchain lead at Broadridge. Let’s see what he has to say!

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

Blockchain is emerging as a huge collaborative innovation that has powered a paradigm shift from centralized applications to decentralized/distributed applications.

Firstly, the important aspect is a change in the development mindset. As we move applications from centralized to decentralized/distributed world, the development mindset needs to be changed as well.  The solution to a problem may work perfectly in the centralized world, but may not work or even be suitable in the distributed world. For example, the matching logic in the current world business workflows will not be necessary and it can be completely re-designed in the distributed world by multi-party approval process where one party submits a transaction and other party approves/rejects, another example is, the existing data models will no longer be viable as we build granular data privacy requirements and require new data models.

Second, the technology is certainly not fully matured and still has several complex unsolved problems such as scalability, data archival and interoperability which need to be solved for before it can be productionized. Technologists should grab this opportunity to solve the problems and this brings with it immense learning, experience and a chance to innovate.

Third, we are seeing the technology rapidly evolving in both public and private blockchain space. As a developer, one should be open to both public or private blockchain implementations, both have subtle differences but it’s always helpful to be cognizant of pros and cons, design patterns, and application while implementing the use case.

Two years back, I started my journey with Hyperledger Fabric at Broadridge and we’ve always been at the forefront of experimenting with the latest version and testing Fabric for real-world use cases in the financial services. We believe some of the specific privacy, asset modeling requirements in the financial services are very critical to productionize the solution and we as technologists continue to provide the feedback or suggestions to the Fabric community. With this emerging technology, it is very important to share learning and best practices that mutually benefits the development community.

Hrishikesh Nashikkar, Blockchain Lead, Broadridge

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

I am currently working in Broadridge Blockchain Centre of Excellence and leading our efforts on Hyperledger Fabric and post-trade blockchain based projects.

Broadridge is the global fintech leader and plays a crucial role at the center of the financial services industry. We have been driving innovation and adoption of new technologies like Machine learning, Blockchain, Robotic Process Automation to solve real-world problems. Blockchain is one of the key technologies in our innovation strategy. We believe, Blockchain offers a high level of transparency, auditability, data privacy and security and this will certainly bring significant value-add, cost-saving and operational efficiency to our clients.

Given my background of a developer and subsequent exposure to the financial markets as a Business Analyst, Blockchain seemed like the next best choice for me as a career, as I can combine both of my skills to deliver next-gen solutions in the financial markets.

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

We at Broadridge have been extensively using Hyperledger Fabric for our internal POCs/Pilots since its initial versions.

Recently, Broadridge announced the successful completion of a pilot with Natixis and Societe Generale which leverages blockchain technology to enhance the operational efficiency, reduce risks and auditability of bilateral repurchase, or repo, agreements. The Bilateral Repo solution is for Broker-dealers and Buy-side firms that automate end-to-end processes, streamlines the repo agreement and confirmation processes, offers a faster and more accurate collateral substitution, valuation process and other mid-life events, while eliminating time-consuming manual interventions, and reduces counterparty risk while increasing auditability.

We have utilized Hyperledger Fabric v1.0 to facilitate private/permissioned network between Broadridge and its partners in the pilot. Overall, my experience is – Fabric has performed reasonably well with our pilot requirements during the testing, despite showing few pain points of an emerging technology. The development community has been very supportive and quickly helped us on the critical issues.

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

I think blockchain is rapidly evolving through enterprise, open-sourced or consortiums based developments. Many blockchain frameworks are available in different flavors, sizes and complexity levels. One of the key requirements is interoperability between different platforms. Various blockchain based application development projects or initiatives are being developed in silos. We see mixed opinions on the different blockchain frameworks and it is difficult to pinpoint the winner at the moment. It’s quite apparent, we’ll witness different blockchain frameworks being used in the industry.

This leads to few important questions. How will different blockchain frameworks co-exist and integrate with different standards of networking, data privacy and security, identity or crypto specifications, assets, smart contracts? Another critical question is – how do we manage interoperability between different legacy systems and new blockchain platforms with complex business logic and data storage? These questions become increasingly important when we set our path to productionize the use case and network with multiple participants with their own choice of blockchain technology.

Obviously, some of these questions are being brainstormed or addressed to a certain extent. But, secure, robust operational designs and common standards need to be incorporated to build the strong ecosystem for the future.

I believe, Hyperledger is playing an important role as a technology incubator in the industry and has multiple cross-industry blockchain projects under its umbrella. Hyperledger is the best platform to start addressing some of these problems and build common standards across different blockchain frameworks.
