DID Method Onion Specification

• <img src="https://raw.githubusercontent.com/BlockchainCommons/torgap/master/images/logos/torgap.png" width=30 valign="bottom"> part of the torgap technology family

This specification describes a W3C DID Method related to Tor Hidden Services.

The web-hosted version of the spec itself is at: https://blockchaincommons.github.io/did-method-onion/

The spec text can be edited as PRs to the html at: https://github.com/BlockchainCommons/did-method-onion/blob/main/index.html.

This spec text supports conversion that leverages the W3C CCG Respec template's javascript, though that feature is currently turned off in this release as we have not yet submitted this spec to the W3C Credentials Community Group (CCG), nor have they accepted it as a work item.

Additional Information

• did-onion discussion in the Airgapped Wallet Community
• W3C Credentials Community Group public group email archive

Goals

Our medium-term goal is to submit this specification to the W3C Credentials Community Group. However, we want to incubate it more at Blockchain Commons first.

The addition of this did:onion spec has been proposed to the DID Method Registry in PR 163 but we are required to finish the "Security and Privacy Considerations" section.

In particular, we'd like to review more with our community how close we want to keep did:onion to did:web, and if we want to incorporate some elements of did:peer or KERI or to leverage services like Open Time Stamps.

Status - Experimental and Early Provisional

DID Method Onion Specification is currently under active development and in the early experimental phase. It should not be used for production tasks until it has had further testing and auditing.

Discussions

The best place to talk about Blockchain Commons and its projects is in our GitHub Discussions areas.

Gordian System Discussions. For users and developers of the Gordian system, including the Gordian Server, Bitcoin Standup technology, QuickConnect, and the Gordian Wallet. If you want to talk about our linked full-node and wallet technology, suggest new additions to our Bitcoin Standup standards, or discuss the implementation our standalone wallet, the Discussions area of the main Gordian repo is the place.

Wallet Standard Discussions. For standards and open-source developers who want to talk about wallet standards, please use the Discussions area of the Airgapped Signing repo. This is where you can talk about projects like our LetheKit and command line tools such as seedtool, both of which are intended to testbed wallet technologies, plus the libraries that we've built to support your own deployment of wallet technology such as bc-bip39, bc-slip39, bc-shamir, Shamir Secret Key Recovery, bc-ur, and the bc-crypto-base. If it's a wallet-focused technology or a more general discussion of wallet standards,discuss it here.

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 the Gordian System or the wallet standards, each of which have their own discussion areas.
