Certified Hyperledger Fabric Developer (CHFD) Exam Has Relaunched
The Certified Hyperledger Fabric Developer (CHFD) exam, which initially launched a year ago and enables candidates to demonstrate the knowledge to develop and maintain client applications and smart contracts using the latest Fabric programming model, is once again available for scheduling. The exam had been paused pending updates of the exam content to align with the most recent Long Term Support (LTS) version of Fabric, v2.2.
Holding this certification provides confidence to supervisors and hiring managers that a team member or job candidate possesses the necessary skills to package and deploy Fabric applications and smart contracts, perform end-to-end Fabric application life-cycle and smart contract management, and more. The CHFD exam platform is Node.js for both Client Application and Smart Contract.
As with other Linux Foundation certification exams, CHFD can be taken remotely from a candidate’s home or workplace. Candidates can choose from an English or Japanese speaking proctor who will verify the candidate’s identity and monitor them during the exam via webcam – the exam questions are available in both English and Japanese within the exam environment. The two-hour exam is an online, performance-based test that consists of a set of tasks or problems to be solved in a Web IDE and the command line.
CHFD and CHFD-JP are available for immediate registration. For those needing assistance preparing for the exam, the LFD272 – Hyperledger Fabric for Developers training course is also available and covers topics such as how to implement and test a chaincode in Golang for any use case, manage the chaincode life cycle, create Node.js client applications interacting with Hyperledger Fabric networks, control access to the information based on a user identity, set up and use private data collections and much more.

Generating a Software Bill of Materials (SBOM) with Open Source Standards and Tooling
Every month there seems to be a new software vulnerability showing up on social media, which causes open source program offices and security teams to start querying their inventories to see how FOSS components they use may impact their organizations.
Frequently this information is not available in a consistent format within an organization for automatic querying and may result in a significant amount of email and manual effort. By exchanging software metadata in a standardized software bill of materials (SBOM) format between organizations, automation within an organization becomes simpler, accelerating the discovery process and uncovering risk so that mitigations can be considered quickly.
In the last year, we’ve also seen standards like OpenChain (ISO/IEC 5320:2020) gain adoption in the supply chain. Customers have started asking for a bill of materials from their suppliers as part of negotiation and contract discussions to conform to the standard. OpenChain has a focus on ensuring that there is sufficient information for license compliance, and as a result, expects metadata for the distributed components as well. A software bill of materials can be used to support the systematic review and approval of each component’s license terms to clarify the obligations and restrictions as it applies to the distribution of the supplied software and reduces risk.
Kate Stewart, VP, Dependable Embedded Systems, The Linux Foundation, will host a complimentary mentorship webinar entitled Generating Software Bill Of Materials on Thursday, March 25 at 7:30 am PST. This session will work through the minimum elements included in a software bill of materials and detail the reasoning behind why those elements are included. To register, please click here.
There are many ways this software metadata can be shared. The common SBOM document format options (SPDX, SWID, and CycloneDX) will be reviewed so that the participants can better understand what is available for those just starting.
This mentorship session will work through some simple examples and then guide where to find the next level of details and further references.
At the end of this session, participants will be on a secure footing and a path towards the automated generation of SBOMs as part of their build and release processes in the future.

The TARS Foundation Celebrates its First Anniversary
The TARS Foundation, an open source microservices foundation under the Linux Foundation, celebrated its first anniversary on March 10, 2021. As we all know, 2020 was a strange year, and we are all adjusting to the new normal. Meanwhile, despite being unable to meet in person, the TARS Foundation community is connected, sharing and working together virtually toward our goals.
This year, four new projects have joined the TARS Foundation, expanding our technical community. The TARS Foundation launched TARS Landscape in July 2020, presenting an ideal and complete microservice ecosystem, which is the vision that the TARS open source community works to achieve. Furthermore, we welcome more open source projects to join the TARS community and go through our incubation process.
In September 2020, The Linux Foundation and TARS Foundation released a new, free training course, Building Microservice Platforms with TARS, on the edX platform. This course is designed for engineers working in microservices and enterprise managers interested in exploring internal technical architectures working for digital transmission in traditional industries. The course explains the functions, characteristics, and structure of the TARS microservices framework while demonstrating how to deploy and maintain services in different programming languages in the TARS Framework. Besides, anyone interested in software architecture will benefit from this course.
