Maintainers from four Hyperledger projects to serve as code contribution guides during AnitaB.org Grace Hopper Celebration

By Hyperledger Blog, Hyperledger Besu, Hyperledger Cactus, Hyperledger Indy, Hyperledger Labs

Hyperledger is once again sponsoring the annual AnitaB.org Grace Hopper Celebration as a way of supporting leaders and future women technologists in our global community. Hyperledger and the Linux Foundation are committed to supporting women-led initiatives centered around recruitment and engagement like AnitaB.org.

This year, Hyperledger is putting its resources behind Open Source Day (OSD), an all-day hackathon for participants of all skill levels to learn about open source while contributing to projects designed to solve real world problems. OSD will be held October 1 as part of this year’s Grace Hopper Celebrations (vGHC).

During OSD, the women taking part will spend the day diving into the open source world to level up their skills and start contributing code. Participants will work in groups and with the mentors for hands-on learning, tailored to their experience level.

Hyperledger is an official Open Source Partner Project for OSD and is teaming with maintainers from four Hyperledger projects to introduce participants to its diverse ecosystem. Maintainers from these projects will on hand as guides to both the Hyperledger technologies and the code contribution process:

Hyperledger Besu, an Ethereum client designed to be enterprise-friendly for both public and private permissioned network use cases;
Hyperledger Cactus, a blockchain integration tool designed to allow users to securely integrate different blockchains;
Hyperledger Indy, a framework that provides tools, libraries, and reusable components for providing digital identities rooted on blockchains or other distributed ledgers; and
Firefly, a Hyperledger Lab, a multiparty system for enterprise data flows, powered by blockchain.

For each of these projects, the maintainers have compiled an array of pull requests or tasks that are tagged as “Good First Issues” that participants can tackle as their initial code contributions to Hyperledger. These triaged, non-documentation requests include everything from bug fixes to enhancements to security plug-ins. For those who want to challenge themselves or move deeper into a project, the Hyperledger Cactus list is broken down based on level of experience:

We want to thank our maintainers Anastasia Lalamentik (FireFly), Grace Hartley (Besu), Justin Florentine (Besu), Linlu Liu (FireFly), Nicko Guyer (FireFly), Peter Somogyvar (Cactus), Renata Toktar (Indy), and Tracy Kuhrt (Cactus) for offering their time and expertise to OSD. They will play a vital role in welcoming the Grace Hopper community into the world of open source and setting them up for success as contributors to Hyperledger and other projects.

“The Hyperledger Mentorship Program was my first stint as an open source contributor, and I am very proud to complete it successfully. The whole Hyperledger community and Iroha team, especially my mentor, Grzegorz Bazior, were always there to clear my doubts and queries. I learned a lot throughout this mentorship program about Hyperledger Iroha’s architecture and its working, writing code with better readability and working in an open source community. As a beginner in the industry, I found the experience gained invaluable and a big stepping stone in my professional career. I want to thank Hyperledger and the Linux Foundation for providing me with this opportunity.”

Mentor

Grzegorz Bazior

Yonix Digital Systems

“I was invited to be a Hyperledger Iroha maintainer five months ago and then I was asked to be mentor. It was my first time being mentor of an open source project. I work as academic teacher, so I’m used to observing students learning and making progress. Being a mentor is different – we can observe progress of useful practical project from beginning until end. It takes time, but it is worth of all that effort when the project is finally completed and is great quality work.

When this project started, I was afraid that it couldn’t be completed. Fortunately Ayush managed to complete it once I guided him through how Hyperledger Iroha works.”

A special thanks to the Hyperledger member companies for funding this important program. To learn more about our Hyperledger Mentorship Program and how you can participate in our next cohort, head over to our program overview page on the Hyperledger wiki.

Highlights from the “Enterprise Blockchain And The Hyperledger Brand” report from Linux Foundation Research

By Hyperledger Blog, Research

Over the summer, Linux Foundation Research undertook an independent and formal survey to help Hyperledger better understand the market and our brand. The research team collected quantitative and qualitative data from a broad community with knowledge of enterprise blockchain covering a range of topics, including brand familiarity and perceptions for Hyperledger and its projects as well as other blockchain technologies. The survey also looked at broader trends, opportunities and challenges in the enterprise blockchain space.

The resulting report, Enterprise Blockchain And The Hyperledger Brand, details a number of interesting findings and confirms much of the progress both the industry and Hyperledger have made in just over five years. Below are a few key highlights from the report:

“Blockchain technologies are here to stay, and savvy enterprise users are preparing their organizations for the next wave of blockchain innovation, driven by the scaling of use cases. By and large, survey respondents expected blockchain to become a core technology (59% of respondents said they ‘agree strongly’ with this statement) that will enable new business models to emerge (69% strongly agreed).”

“Hyperledger has many strengths to build on, according to the survey. Among them are its open-source paradigm (74% said this described Hyperledger ‘completely’), its trustworthiness (61%), its strong governance model (54%), its affiliation with a nonprofit foundation (54%), and support from leading companies (54%). Respondents viewed Hyperledger favorably as built by and for enterprise users (53%) and always evolving to meet new demands (50%).”

However, the report also highlights places where there is work still to be done in terms of driving adoption and in brand building, especially for the full range of Hyperledger projects. For example

“Although they come in all shapes and sizes, enterprise blockchains face common problems across the space. Survey respondents identified these as the top challenges:
- lack of technological maturity (58%)
- difficulty of adopting and integrating with legacy systems (50%)
- difficulty of explaining to senior management (49%)
- regulatory risks (48%).”

“A higher proportion (30%) of respondents were ‘extremely familiar’ with Hyperledger Fabric than with Ethereum (28%), ConsenSys Quorum (12%), or Corda (7%). However, only seven percent described themselves as extremely familiar with Hyperledger Indy, and the numbers were even smaller for Hyperledger Besu (6%); Hyperledger Sawtooth (6%); Hyperledger Burrow (3%); and Hyperledger Iroha (3%). At the other end of the scale, only 12 percent of respondents had ‘not heard of’ Hyperledger Fabric but higher proportions had not heard of Hyperledger Indy (27%), Hyperledger Besu (30%), Hyperledger Sawtooth (24%), Hyperledger Burrow (32%), and Hyperledger Iroha (34%).”

The report and a full breakdown of the survey findings are available to Hyperledger members. Find out more about Hyperledger Membership here.

Being a mentor is different – we can observe progress on a useful practical project from beginning until end. It is taking time, but it is worth of all that work when the project is finally completed and is great quality.

It was great to be a co-mentor with Peter, who has much more experience with the process then I do. I’ve learned a lot from him. It was also great to work with Han, our mentee. How he works, the questions he asks and his weekly presentations were all really impressive.”

Peter Somogyvari
“Being a mentor on this project exposed me to another Hyperledger project (Iroha) as well as the implementation work itself. It was great to get to know my co-mentor, Greg, who helped carry the load and introduced me to some of the specifics of the Iroha project for which I’m grateful.

This project has also given me more information about how people interact with Hyperledger Cactus when they are new to it. This is very valuable for me as a Hyperledger Cactus maintainer given that our top priority is to grow the open source software community around the project.

Han, our mentee, did an excellent job, and I hope to work with him again in the future.”

“I’m glad I decided to work as a mentee this mentorship season. It’s really great how this community has helped me grow and learn more about blockchain and how to work with small teams and communicate effectively. We initiated a community effort within these three months, and I am very excited to see where this project goes from here.

I’m happy I got a chance to work with my amazing mentor Alfonso Govela. He was supportive, motivating, and his vision about this project is very clear. I learnt about how to handle and work with Graph databases and about the blockchain ecosystem.

Thanks everyone!”

Mentor

Alfonso Govela

Co-Founder of Hyperledger Latinoamerica

“Our current Mentorship Program is an excellent opportunity to explore new territories and bring in mentees to foster budding ideas, solve concrete issues, or create new tools for collaboration in our open-source community. However, three months seems so short. Time passes by quickly, and we want to continue at the end of the summer.

On the other hand, a top-level dialogue goes on regularly in our Hyperledger Communities. Members from all geographies, specialties, ages, and levels of experience discuss and share foundational and functional aspects of DLT/blockchain. At Hyperledger Special Interest Group, Working Groups, Labs, and Meetup Groups, knowledge grows every week. A permanent Mentorship Program would benefit us all.

Like apprenticeship at guilds, an ongoing Mentorship Program could formalize an interest in learning skills, and what better way to understand a subject than contributing to its formulation and development.”

Hyperledger In-depth: An hour with Thales

In 2019, 7.9 billion data records were breached. And yet, 39% of companies aren’t using robust data security measures because deployment complexity is a barrier. Security is not a nice-to-have feature. It’s not an opt-in. It’s a must. No one will buy your solution if they cannot trust it. It’s no wonder companies are exercising diligence when choosing a solution, ideally one that is system agnostic, automated, and simple. In this discussion, Blair Canavan of Thales and Avesta Hojjati of DigiCert will discuss how to incorporates critical levels of security into the blockchain, increasing the integrity of solutions built using Hyperledger Fabric.

How Thales and DigiCert enhance cybersecurity for Hyperledger Fabric-based networks

By Hyperledger Blog, Hyperledger Fabric

In 2019, 7.9 billion data records were breached. And, yet, 39% of companies aren’t using robust data security measures because deployment complexity is a barrier. Still, security is not a nice-to-have feature. It’s not an opt-in. It’s a must. No one will buy your solution if they cannot trust it.

So, are DLTs the answer to your cybersecurity concerns?

DLTs promise a lot: immutability, transparency, and auditability. Once the network achieves a consensus and information is put on a ledger, users can trust what they’re seeing is identical to what was approved as “truth.” And, if the data is encrypted, only users who are approved will be able to see it. In these ways, DLTs secure data.

However, as with any storage solution, blockchains are not immune to compromise. They are not, by themselves, 100% secure. Blockchains are only one part of an entire system—what happens before the consensus and what happens after data is retrieved has nothing to do with DLTs.

To be secure, blockchain and DLT solutions must still meet standard cybersecurity practices and requirements. Key management—making sure that keys are kept confidential, their integrity is protected, and they are always readily available—is critical.

Understandably, key management is a constant challenge for companies. They don’t have just one set of keys to secure or a few documents to protect. Enterprises can generate many hundreds of key pairs an hour—and each key contains from 2048 to 3072 bits.

With remote employees and partners, multiple devices accessing networks, and secure email and document exchange, enterprises authenticate identities, encrypt data, and verify the integrity of documents and communications countless times a day.

That’s a lot of information to manage and secure. It requires a robust platform for certificate, key, and identity management; and it requires a way to generate, manage and store the private keys.

And this is where DigiCert and Thales come together with a joint solution for authenticating and managing the identity of blockchain and DLT users and devices. Simply put, DigiCert secures devices with keys and Thales secures those keys. And together they serve to secure solutions built on Hyperledger Fabric.

To start, a client creates an account within DigiCert’s platform, which allows the client to issue publicly and privately trusted certificates. Then they use DigiCert’s API to integrate it with Hyperledger Fabric and replace the native CA (Certificate Authority). From that point, clients can use Thales Luna HSM (Hardware Security Modules) as a strong foundation of digital trust.

Though the integrations are separate now, the companies aim to have a single product with one point of contact for key pairs and certificates.

Hyperledger worked up with Thales and DigiCert on a case study that details how their joint solution incorporates critical levels of security into the blockchain, increasing the integrity of solutions built using Hyperledger Fabric. It also delves into the challenges of identity authentication and management with the increasing deployment of IoT devices and distributed networks and includes details on key management best practices.

Read the full case study here. For more details, tune into the Wednesday, September 15, discussion with Blair Canavan of Thales on increasing cybersecurity for Hyperledger Fabric.
