Update on the Hyperledger Fabric 1.1 Roadmap

By | Blog, Hyperledger Fabric

Guest post: Hyperledger Fabric 1.1 release manager, Chris Ferris

One of the questions I am often asked is “Is there a roadmap for Hyperledger Fabric development?” I usually to point people to the Hyperledger Fabric wiki, because for the most part, we try to be pretty transparent about plans for our next release. Our challenge is to try to make the information a bit more visible and accessible.

Since we launched Hyperledger Fabric 1.0.0, the maintainers have published patch releases on a (roughly) monthly basis (v1.0.1 – v1.0.4). We want to continue to deliver monthly patch releases on the 1.0.0 release branch until we release Fabric 1.1.0 sometime in Q1 2018, at which point we will discontinue patch releases for the 1.0.x release branch and start publishing monthly patch releases for 1.1.x release branch.

Our roadmap plan (generally) is to publish approximately one minor release per quarter once we get v1.1.0 finished. We will be also be exploring the adoption of a long-term support (LTS) strategy possibly starting with the v1.2.0 release. What this would mean is that the maintainers would continue to publish patch releases on a designated LTS release for up to a year (initially) afterwards, even if we publish a major or minor release in the interim.

As for which new features we’re tracking in the roadmap for the 1.1.0 release, those can be found in the wiki, as well. The wiki also links to each feature’s JIRA item which tracks the feature development and would typically include any design documents, etc.

We are also tracking a set of experimental features that can be enabled through a re-compile of the Hyperledger Fabric codebase via the wiki. You can generally expect, that these experimental features would be formally supported in the subsequent release (1.2.0 in this case).

We also track the progress of each feature in our next release in our JIRA dashboard (see gadget in the upper left).

The Hyperledger Fabric Maintainers are always interested in feedback (positive and negative) as well as proposals for new features. Anyone can weigh in through one or more of the various communication channels (chat, email, or posting directly to JIRA) and either offer recommendations, or specific proposals.

Meet the TSC: Baohua Yang, Oracle

By | Blog, Hyperledger Fabric

Back to our blog series that focuses on the motivations and backgrounds of the individuals that make up Hyperledger’s Technical Steering Committee (TSC). The TSC is a group of community-elected developers drawn from a pool of active participants and is a core element of Hyperledger’s Open Governance model. The TSC is responsible for all technical decisions – from which features to add, how to add them and when, among others.

Now let’s introduce the next Hyperledger TSC member, Baohua Yang from Oracle . Let’s see what he had to say about Hyperledger, his role in the TSC and the community!

How are you or your company currently using Hyperledger technologies or how do you plan to?

We are glad to join Hyperledger to help strengthen the underlying infrastructure for blockchain and distributed ledger technologies, especially to enhance the fundamental elements in scalability, security and interoperability. We recently launched Oracle Blockchain Cloud Service, our first blockchain as a platform service, which uses Hyperledger Fabric as its foundation. Leveraging Hyperledger’s technology with our own innovation, we are offering an enterprise-grade blockchain platform that is fully managed by Oracle and provides customers rapid provisioning and simplified operations with built-in monitoring, continuous backup, and point-in-time recovery.

What are the benefits of Hyperledger’s open governance model? 

The open governance model encourages collaboration among leaders and organizations in the industry, and academia to raise prevalent topics. It invites more voices to the community to share opinions, offer idea concepts, and engage to help ensure the proper design and implementation of distributed ledger technology components. Ultimately, this all helps create an active and healthy ecosystem. The more we can invite people into the discussions and development, the greater the chance for wider adoption of this exciting new technology.

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

There are a number of fundamental techniques required for working in blockchain, including distributed system architecture, cryptography and control theory. For anyone interested in exploring a career in blockchain, these are key areas I would recommend you emphasize. But, that being said, it is just as important to keep an open mind, and make an effort to have conversations with others. The only way we get better is through experience, discussions and exploration, so don’t be shy to ask question and try new things. I’d encourage anyone exploring blockchain technology to clone the available code and see what happens!

What’s the biggest struggle or challenge you see Hyperledger having to overcome?

As a joint effort from a number of enterprises and community developers, Hyperledger has been widely adopted in various scenarios. It would be beneficial to the larger Hyperledger community if we were able to collect feedback from previous adoptions in a streamlined process. This would allow us to quickly evolve the technology to meet real-world requirements in finance, supply chain, healthcare, and many other industries. In addition, we would love to help individuals and organizations quickly get started with blockchain technology and Hyperledger through additional education activities such as seminars, training sessions, documentations and more. Blockchain is quickly becoming a critical technology for enterprises and the more we can help others embrace this technology, the stronger the network becomes.

What use cases are you most excited about with Hyperledger and/or blockchain?

We are very excited by the promise that Hyperledger and blockchain technologies, in general, can help improve transactions in many industries, including supply chain and the financial services industry. From improving the traceability food and parts in transport, to improving invoice factoring, blockchain can reduce the total cost of complicated process, and increase the transparency and agility with fewer resource. We are excited to help build this foundation, encourage its growth and help other industries realize the benefits of blockchain.

UN-pluggable Consensus With Hyperledger Sawtooth

By | Blog, Hyperledger Sawtooth

We have an exciting technical update to share! Hyperledger Sawtooth now supports un-pluggable consensus. That means you can easily change all blockchain settings by submitting a transaction to the network – including changing the consensus algorithm on the fly. This transition happens, like all state, at the block boundary.

When we designed our 0.8 architecture this year a big part of it was putting all blockchain configuration on the chain itself. That includes the selection of consensus algorithm.

The benefit is you can start a network with a small-scale or lax byzantine consensus algorithm and change as your network grows. And that change does not require you to stop all validators, flush your state, and start over with a new genesis block. There’s no outage at all involved in changing consensus. Coordination among peers to change consensus is implicit with this being a blockchain transaction.

In our 0.8 stable builds you can submit transactions to change between DevMode, PoET, and PoET-SGX. The initial development to add Raft is underway. We anticipate adding full support for Raft after we get Hyperledger Sawtooth 1.0 release completed this year.

For more information, you can review this presentation:

If you’re interested, you can learn more about Hyperledger Sawtooth and see real world examples of how the technology is being used. You can also read the documentation, join the community on RocketChat or pull the code from GitHub to kick the tires today.


Developer Showcase Series: Chris Kowalski, Blockchain Tech Labs

By | Blog

Our Developer Showcase blog series serves to highlight the work and motivations of developers, users and researchers collaborating on Hyperledger’s incubated projects. Next up is Chris Kowalski an engineer at Blockchain Tech Labs.

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

My advice to offer other technologist is to start right on. The blockchain space offers a dynamic set of unique opportunities to work in a field that is not that explored from other developers hence you can easily stand out. The parallels with the foundation of the web in the 90s are so many and working on blockchain projects can empower developers, so they leave their footprint. Not to underestimate the demand for skilled engineers from financial perspective however with blockchain coming more and more to surface this is an area that offers endless opportunities. There are many projects out there looking to pay premium salary for the top talent in this area.

Getting into blockchain development will require dedication, continuous improvement and a lot of reading but it’s definitely worth it 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?

I have been involved with cryptography since my university years. In addition for the last 5 years I have been working on various blockchain projects including ATMCoin, Clinicubes and others. For me as a software engineer, this was an interesting challenge and offered me the chance to meet really amazing, talented people. We are lucky to have some of the smartest developers working on Blockchain/DLT projects and this had motivated me to be a part of this technology.

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

We have started with Hyperledger Fabric and had been successfully implementing several Proof of concepts such as a Supply Chain demo, Mortgages product and Clinical Trails Management infrastructure. When Hyperledger Composer came out it was the natural move for us. It made development and testing so much easier. Since we grew in numbers within Blockchain Technology Labs it made it easier and faster for our new team members to adapt to Hyperledger quicker.

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

I would say building more developer tools and improving on the awesome work done on the Composer framework but also getting some out-of-the-box testing and automation tools.

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

Hyperledger would still be the preferred infrastructure for permissioned based blockchain and thus preferred for Enterprise applications. I don’t see that changing anytime soon. The adoption and support from Intel and IBM is key for this success. I expect blockchain type of protocols to be everywhere and replacing centralized infrastructure.
