Block, a global technology company with a focus on financial services, today joined OpenChain’s Governing Board. Block, made up of Square, Cash App, Spiral, TIDAL, and TBD, builds tools that help make the economy more accessible for everyone. The OpenChain Project has been building trust in the supply chain since 2016. It maintains OpenChain ISO/IEC 5230, the International Standard for open source license compliance. This is a simple, effective standard suitable for companies of all sizes in all markets. It is developed openly by a vibrant user community and freely available to all.
“Welcoming Block to the OpenChain Governing board is a landmark moment for our project,” says Shane Coughlan, General Manager at OpenChain. “The financial sector is one of the areas where regulation is most important, and where getting things done correctly is of vital significance. Managing the supply chain is an issue here as it is everywhere, and OpenChain standard for open source compliance helps to mitigate this challenge. We are proud to be part of the solution for Block and we look forward to working with many other financial companies in the future.”
“Managing supply chains is not something that a company does alone. It is a combined industry effort to reduce errors and to increase efficiency,” says Max Sills, Counsel at Block. “At Block, we recognize that OpenChain is a critical part of this in the open source ecosystem, and we see immense value in being part of the strategic management around the ISO standard and the global community. We look forward to helping the open source supply chain become more efficient and more effective together.”

Shane Coughlan, OpenChain General Manager, will take the lead in a FOSSA webinar on the 16th of March.
From their site:
Software supply chain security has dominated the headlines in recent months following a series of events (including the SolarWinds hack and the Biden Administration’s executive order). But maintaining the integrity of your software supply chain is about more than just traditional vulnerability remediation. Our modern threat landscape has elevated the importance of supply chain sustainability, which includes areas like software provenance and lifecycle management in addition to known vulnerability mitigation.
Join Shane Coughlan, GM of OpenChain (a Linux Foundation project) for a conversation on the importance of supply chain sustainability and practical steps your organization can take to strengthen supply chain integrity.
We’ll discuss:
- The evolution of software supply chain threats
- The importance of software provenance, such as package origin, maintainers, and quality
- Questions to ask vendors to gauge the sustainability of proprietary software
- Indicators of sustainable open source software

Open source, security, supply chain, sustainability. In this informal discussion we had a chance to cover it all.
This webinar unpacked the Mulan license family, an emerging activity from China with implications regarding the governance of open source as it expands around the world. Providing licenses designed in non-English languages is a topic that will be increasingly important, and is something companies will benefit from being aware of.

You can expect to come away with a clear understanding of market conditions, how the Linux Foundation is addressing them, and where OpenChain fits into the picture. The goal – as always – is to ensure you have the information necessary to make informed, effective decisions around the open source supply chain.
We seek to build trust in the quality of programs used by you, your customers and your suppliers. We are proud to have taken significant strides in our field throughout 2021. We expect to push the boundaries of what is possible once again in 2022. You can learn more about what we are doing around security – including our reference assurance guide – here:
We are turning this into a Reference Security Specification via our bi-weekly global work team calls. You can via the current draft on GitHub and open issues here:

The OpenChain Open Source Policy Template helps apply the key requirements for a quality open source compliance program. It provides sample policy text that helps organisations select, classify, incorporate and publish open source code with a focus on legal compliance of open source.
This template has been available in English for several years thanks to the hard work of Andrew Katz, the teams at Moorcrofts and Orcro, and the broader OpenChain community. Now, thanks to Masahiko Hayashi and the team at NEC, this policy template is available in Japanese.
This is an excellent resource to help you conform to OpenChain ISO/IEC 5230:2020 or to simply improve your internal process management for open source.

The China Academy of Information and Communications Technology (CAICT) hosted an OpenChain event today at their HQ in Beijing. Thirty-seven representatives from various companies attended in-person. As the world opens, the OpenChain community hopes to hold similar events across Asia, Europe and North America.
This event highlighted the recent Third-Party Certification by General Data Technology Co., Ltd., CETC Kingbase and PingCap while providing attendees with extensive information on OpenChain ISO/IEC 5230, conformance options, and support for conformance in the Chinese market.
The event featured an introduction by Shane Coughlan, OpenChain General Manager, before switching fully into Mandarin and providing attendees with a chance to discuss matters in a frank, open and productive manner.
We would invite all interested parties to take part in the OpenChain China activities. Everyone is invited. We keep the discussion informal, focused and helpful.
