Passkey-only identity for collaborative web apps on Cloudflare Workers and Durable Objects

Gordian Sealed Transaction Protocol (GSTP) is a secure, transport-agnostic communication method enabling encrypted and signed data exchange between multiple parties. Built upon the Gordian Envelope specification, GSTP supports various transport mediums - including HTTP, raw TCP/IP, air-gapped protocols using QR codes, and NFC cards

XIDs are unique 32-byte identifiers that represent any entities - real or abstract - such as a person, organization, or device. Generated from the SHA-256 hash of a specific public signing key known as the inception key, a XID provides a stable identity throughout its lifecycle, even as associated keys and permissions evolve.

Provides a pattern matching language for querying and extracting data from Gordian Envelope structures. It extends the dCBOR pattern matching capabilities with envelope-specific patterns for subjects, predicates, objects, assertions, and wrapped envelopes.

Provenance Marks provide a cryptographically-secured system for establishing and verifying the authenticity of works in an age of rampant AI-powered manipulation and plagiarism.

Provides a powerful pattern matching language for querying and extracting data from dCBOR (Deterministic CBOR) structures. It supports value matching, structural patterns, and meta-patterns with named captures.

Gordian Envelope is a structured format for hierarchical binary data focused on privacy. They are designed to facilitate "smart documents" with a number of unique features: Hierarchical structure, Merkle-like digest tree, Deterministic representation, Privacy-focused, Progressive trust

Provides tools for parsing and composing the CBOR diagnostic notation into dCBOR (Deterministic CBOR) data items.

The registry of ontological predicates used in Gordian Envelope, encoded as compact integers instead of strings.
