Gordian Clubs are built atop the Gordian stack. Following is a listing of the major building blocks.

Data Encoding & Storage

Identity, Verification & Authorization

Communication

  • 🔒 GSTP: Secure Multi-Party Coordination
    • Transport-agnostic protocol (works over Bluetooth, QR, NFC)
    • Encrypted message exchange with state preservation
    • Enables secure coordination without infrastructure
    • Can support multiparty signing of new Editions
    • Can release Edition updates (but this infrastructure is not required)

Schnorr

Cryptographic Maturity Levels

The cryptography within Gordian Clubs is at variable levels of maturity. Audits are needed for some systems, while others are in a research phase that might enable future capabilities.

Production Ready

  • SSKR for permits (formal security proofs, audited implementations)
  • FROST and MuSig2 for threshold signatures (formal security proofs, audited implementations)
  • ChaCha20-Poly1305 as Gordian Envelope’s core cryptography (proven implementations)

Requires Formal Security Audit

  • Gordian Envelope’s unique elision and permit primitives
  • Schnorr adaptor signatures for single-key capabilities (proven primitive, novel application to access control)
  • Integration of adaptor signatures with Gordian Clubs for read/write delegation
  • Combinations of adaptor signatures with FROST/MuSig2

Research Phase

  • Threshold-based capability delegation (plausible but unproven extensions)
  • Key agreement protocols leveraging FROST/MuSig2 shared material
  • Scriptless scripts for complex authorization logic
