Blockchain Commons is proudly a "not-for-profit" social benefit corporation committed to open source & open development. We are working to enable responsible key management and self-sovereign control of digital assets focused on our four Gordian principles: independence, privacy, resilience, and openness.

We demonstrate these principles through architectures, specifications, reference applications, and documentation. This work is done in conjunction with a group of wallet developers who are helping us to ensure that these new principles for digital-asset management are widely used and interoperable.

Our work is funded entirely by donations and collaborative partnerships with people like you. Every contribution will be spent on building open tools, technologies, and techniques that sustain and advance blockchain and internet security infrastructure and promote an open web.

For our most recent advances, please see our quarterly reports.

Some of our biggest categories of work include:

  • Gordian — The Gordian architecture and principles are the linchpin of our work. Reference apps, hardware kits, and internet services demonstrate their usage.
  • Crypto Commons — The Gordian principles are enabled by specifications such as Lifehash, SSKR (Sharded Secret Key Reconstruction), and UR (Uniform Resources). The Crypto Commons provides libraries for integrating these specifications into your programs, as well as CLI tools that exercise these libraries and demonstrate their usage.
  • Torgap — One of the core architectural elements of Gordian is the torgap, which allows secure and private connections across a network. An increasing number of demos exemplify this usage.

Reference applications released for Gordian include:

We also are working to educate users and developers alike, with documentation projects such as:

These are just the beginning! Blockchain Commons is also working on identity wallets, social-recovery techniques, zero-knowledge curve-operation proofs, advanced cryptographic primitives such as Schnorr, MuSig, and scriptless scripts, and in general establishing multi- and cross-blockchain standards.

To financially support further development at Blockchain Commons, please consider becoming a Sponsor here at GitHub. However, you can alternatively support Blockchain Commons and our vision of the open web with Bitcoin via our BTCPay contribution page.

Blockchain Commons was founded by Christopher Allen (GitHub: @ChristopherA & Twitter: @ChristopherA) who acts as Principal Architect & Executive Director. Christopher is also the founder of Rebooting the Web Of Trust a non-profit supporting human rights decentralized identity.

18 sponsors are funding BlockchainCommons’s work.
