Tuweni is a set of libraries and other tools to aid development of blockchain and other decentralized software in Java and other JVM languages.

Tuweni has been incubating since 2019-03-25.

Three most important unfinished issues to address before graduating:

  1. Finish export notice for cryptographic elements
  2. Continue building a diverse community
  3. Ship a few items on the roadmap (see below) 

Are there any issues that the IPMC or ASF Board need to be aware of?

No issues to report at this time.

How has the community developed since the last report?

We are seeing a few contributions in the bug reports and pull requests offered on the repository. The project is starting to gain good traction.

How has the project developed since the last report?

The project has released a new maintenance release (0.10.0). It is now working now on its next major release, moving to support Java 11+.

Releasing is less and less of a daunting task now - with some automation and documentation, one can issue a release without fear of missing bits anymore.

How would you assess the podling's maturity?

The podling is building its community. As part of this board report, we moved to using Confluence to draft the report together before submitting it.

We also drafted a set of stories and use cases as a roadmap with the goal of using this to also build the community: Roadmap

Date of last release:


When were the last committers or PPMC members elected?

Gordon Martin as committer on 2019-08-01.

Have your mentors been helpful and responsive?

No problem to report.

Is the PPMC managing the podling's brand / trademarks?

Yes. At present, there are no issues nor concerns with the Tuweni mark. We do not anticipate any issues with the mark regarding graduation.
