Blockchain Commons - Gordian Envelope - Swift Reference Implementation

by Wolf McNally

Gordian Envelope is a structured format for hierarchical binary data focused on the ability to transmit it in a privacy-focused way. Envelopes are designed to facilitate "smart documents" and have a number of unique features including: easy representation of a variety of semantic structures, a built-in Merkle-like digest tree, deterministic representation using CBOR, and the ability for the holder of a document to selectively encrypt or elide specific parts of a document without invalidating the document structure including the digest tree, or any cryptographic signatures that rely on it.

NOTE: Until recently this implementation was part of BCSwiftSecureComponents. That package is now a dependency of this package.

Building

Add to your project like any other Swift Package.

Note to Implementers

If you are implementing Gordian Envelope in another language, a basic implementation of the core Envelope functionality includes the that found in the files in Sources/Core folder. Functionality from the Sources/Features folder can be added as needed or for completeness.

Gordian Principles

*Gordian Envelope is a reference implementation meant to display the Gordian Principles, which are philosophical and technical underpinnings to Blockchain Commons' Gordian technology.

Status - Alpha

Gordian Envelope is currently under active development and in the alpha testing phase. It should not be used for production tasks until it has had further testing and auditing. See Blockchain Commons' Development Phases.

Gordian Developer Community. For standards and open-source developers who want to talk about interoperable wallet specifications, please use the Discussions area of the Gordian Developer Community repo. This is where you talk about Gordian specifications such as Gordian Envelope, bc-shamir, Sharded Secret Key Reconstruction, and bc-ur as well as the larger Gordian Architecture, its Principles of independence, privacy, resilience, and openness, and its macro-architectural ideas such as functional partition (including airgapping, the original name of this community).

Gordian User Community. For users of the Gordian reference apps, including Gordian Coordinator, Gordian Seed Tool, Gordian Server, Gordian Wallet, and SpotBit as well as our whole series of CLI apps. This is a place to talk about bug reports and feature requests as well as to explore how our reference apps embody the Gordian Principles.

Blockchain Commons Discussions. For developers, interns, and patrons of Blockchain Commons, please use the discussions area of the Community repo to talk about general Blockchain Commons issues, the intern program, or topics other than those covered by the Gordian Developer Community or the Gordian User Community.
