Rules and Policies Applicable to Hyperledger Marks Owned by The Linux Foundation

In addition to the generally applicable rules discussed in The Linux Foundation Trademark Usage Guidelines, there are a few specific rules that we ask everyone to follow when using trademarks related to one of the Hyperledger projects, special interest groups, or the organization itself.

  • Do mention The Linux Foundation with the first use of Hyperledger Foundation in formal materials (e.g., “Hyperledger Foundation, hosted by The Linux Foundation”) and do use “Hyperledger Foundation” when referring to the organization (e.g., “Acme is a member of Hyperledger Foundation”).
  • Do include a trademark notice with your other similar notices, and include a link to the Hyperledger website, if possible (e.g., “Copyright Acme 2021. All rights reserved.  Hyperledger Foundation is a trademark of The Linux Foundation.  See”).
  • When referring to a specific Hyperledger software project, do use the full project name (e.g., “Acme uses Hyperledger Iroha”) and do refer to it as a “framework” or a “tool,” as appropriate (e.g., “the Hyperledger Iroha framework”, “the Hyperledger Explorer tool”).
  • Similarly, when referring to a specific Hyperledger technical working group or special interest group, do use the full group name (e.g., “Acme participates in the Hyperledger® Social Impact Special Interest Group”).
  • Do let Hyperledger Foundation staff know if you plan an event or are putting out a press release centered around or mentioning Hyperledger Foundation or technologies and contact us if you have any questions about proper trademark use. Do introduce a meetup or event with the short Hyperledger Foundation official introductory presentation, available under the presentations section of the resource center here:
  • Don’t use “Hyperledger Project” to refer to the organization–use Hyperledger Foundation™.  Similarly, don’t use “Hyperledger Project” when you are referring to a specific project hosted by Hyperledger (e.g., “Acme did a proof of concept on Hyperledger” should be “Acme did a proof of concept on the Hyperledger Iroha framework”). As noted above, Hyperledger Foundation hosts many software projects.
  • Don’t modify any Hyperledger Foundation trademarks or logos (e.g., do not abbreviate them, add hyphens or other characters, or change the colors, orientation or any other visual aspect of any logos).
  • Don’t use any Hyperledger Foundation trademark in a misleading way, which includes the following:
    • Don’t use Hyperledger Foundation trademarks in connection with any products or services that are not related to, built for or associated with the software projects hosted by the Hyperledger Foundation.
    • Don’t use your company name possessively with anyHyperledger Foundation trademark  (e.g., “Acme’s Hyperledger,” “Acme’s Fabric,” “Iroha by Acme,” “Acme’s Hyperledger Project,” “Acme’s Hyperledger Sawtooth”).
    • Don’t add your company logo(s) on Hyperledger Foundation marketing materials, such as official presentations, unless expressly permitted to do so by Hyperledger Foundation staff. Don’t create marketing materials that look like they are coming from Hyperledger Foundation rather than your company.
    • Don’t use any Hyperledger Foundation or Hyperledger project logo larger than your own company’s logo(s).
    • Don’t use the Hyperledger Foundation trademarks in a way that creates a sense of endorsement, sponsorship, or false association with Hyperledger Foundation (e.g., “Hyperledger approved,” “Hyperledger certified,” “a product by a Hyperledger Foundation member”) or in connection with a project that has not been accepted into the Hyperledger Foundation organization.
    • Don’t use a Hyperledger Foundation trademark in connection with a Meetup with 3 or more speakers from the same company; use the company’s trademarks.
    • Don’t deliberately give the impression that a company is the “main” company behind Hyperledger Foundation or any of its projects, or is otherwise harmful to the organization, its members or other projects.

The Hyperledger Foundation trademarks have been created and their use is expressly permitted for a specific purpose.  Do not use any Hyperledger Foundation trademarks in any commercial or marketing context other than as expressly permitted in this policy or The Linux Foundation Trademark Usage Guidelines unless you have obtained explicit written permission from the Hyperledger Foundation to do so.

Guidelines for Products/Services Built with Hyperledger Technologies

  • Do use the following format and wording to describe how Hyperledger projects support a product or service offering:
    • [Vendor name] [Product name] [Product version]* for -OR- based on -OR- powered by Hyperledger [Project] [Project version]*
    • *Product Version and Project Version are optional for marketing materials, but must be included in tech specs
    • E.g. Acme Blockchain Services (v1.4) powered by Hyperledger Fabric (v2.0)
