Gordian Developer Community

Mission

Gordian Developer Community is a community of cryptocurrency & identity wallet developers, sharing best practices for paritioned interoperability among multiple vendors on multiple platforms. These best practices include support for hot, cold and multisig cryptographic wallets, research & proposals for data formats and protocols, usage of gaps such as airgaps and torgaps, security and UX for multisig work flows, and other key management and signing issues and topics, particularly those that support the Gordian Principles of independence, privacy, resilience, and openness.

Meetings

Much of our collaborative work is conducted through Meetings. Please sign up for our Gordian Developer lists to be informed of when they occur and please see our meetings page for info from meetings to date.

Technologies

Blockchain Common's Gordian technologies include architectural designs, apps, and specifications. The architectural designs, apps, and the general overview of the system can be found in the Gordian repo while developer-level docs can be found in the Crypto Commons repo. Finally, original research specifications can be found in the Research repo.

The following is a general listing of topics in the three repos, but visiting the individual repos' READMEs can provide more up-to-date information

Discussions

The best place to talk about Blockchain Commons and its projects is in our GitHub Discussions areas.

Gordian Developer Community. For standards and open-source developers who want to talk about interoperable wallet specifications, please use the Discussions area of the Gordian Developer Community repo. This is where you talk about Gordian specifications such as Gordian Envelope, bc-shamir, Sharded Secret Key Reconstruction, and bc-ur as well as the larger Gordian Architecture, its Principles of independence, privacy, resilience, and openness, and its macro-architectural ideas such as functional partition (including airgapping, the original name of this community).

We also have a Signal group and a low-volume announcement mailing list.
