Blockchain Commons Gordian Envelope for TypeScript

Disclaimer: This package is under active development and APIs may change.

Introduction

Gordian Envelope is a structured format for hierarchical binary data focused on privacy. The TypeScript implementation provides a feature-rich reference implementation.

Envelopes are designed to facilitate "smart documents" with a number of unique features:

• Hierarchical structure: Easy representation of a variety of semantic structures, from simple key-value pairs to complex property graphs
• Merkle-like digest tree: Built-in integrity verification at any level of the structure
• Deterministic representation: Uses CBOR with deterministic encoding rules for consistent serialization
• Privacy-focused: The holder of a document can selectively encrypt or elide specific parts without invalidating the structure, signatures, or digest tree
• Progressive trust: Holders can reveal information incrementally to build trust with verifiers

Specification

Gordian Envelope is formally specified in the IETF Internet Draft.

Rust Reference Implementation

This TypeScript implementation is based on bc-envelope-rust v0.42.0 (commit).
