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 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 best practices are the linchpin of our work. They highlights principles of independence, privacy, resilience, and openness. Reference apps, hardware kits, and internet programs 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:

Related projects include:

  • #LetheKit — DIY hardware box and SDK for airgapped cryptography and offline master key management.
  • SpotBit — Bitcoin pricing microservice.

Major documentation projects include:

We also offer services to the community improve the open web's security infrastructure:

  • Security Reviews — risk-based assessments of custody methodologies, operational security procedures, and layer-2 protocols such as payment channels.
  • Infrastructure — support of Tor exit nodes and other blockchain infrastructure & software.
  • Project Support — contractual support or white-labeling of our open-source projects.

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.
