BTCR

  • BTCR DID Method - source - WORK ITEM: BTCR DID Method Spec did:btcr:
    • The Bitcoin Reference DID method (did:btcr) supports DIDs on the public Bitcoin blockchain. The Bitcoin Reference method has minimal design goals: a DID trust anchor based on the Bitcoin blockchain, updates publicly visible and auditable via Bitcoin transactions, and optionally, additional DID Document information referenced in the transaction OP_RETURN data field. No other Personal Identifiable Information (PII) would be placed on the immutable blockchain.
  • BTCR DID Resolver Specification

    This describes the process of resolving a BTCR DID into a DID Document. The draft reference implementation is available at https://github.com/WebOfTrustInfo/btcr-did-tools-js (see didFormatter.js). Note not all steps described in this document are implemented yet.

    See the BTCR playground for a live demonstration. The BTCR playground uses the draft reference implementation BTCR DID resolver.

ION

I'm excited to share with you an early look at our work on a scalable, open src, permissionless Layer 2 network for Decentralized Identifiers that runs atop Bitcoin, developed and supported by Microsoft as an open public infrastructure for all - meet ION: https://t.co/9TOl8oyEVB

Spidchain

Spidchain Whitepaper

  • "offers a platform for self-sovereign identity, including desktop and mobile apps for end-users. It uses Decentralized Identifiers (DIDs) - backed by optionally Bitcoin or Ethereum - to implement a marketplace for verifiable claims. The Spidchain applications allow individuals to create, recover, and revoke DIDs, to authenticate, to sign and verify files and claims, and more."
