DIDs Demystified: A hands-on intro to DIDs via the BTCR DID Method – Kim Hamilton Duffy – Webinar 5

Kim Hamilton Duffy, CTO of Learning Machine, Principal Architect of Blockcerts and co-chair W3C Credentials Community Group, will be our next guest to share her knowledge with the global SSI (Self-Sovereign Identity) community.

This talk will demystify Decentralized Identifiers (DIDs) via the simple Bitcoin Reference (BTCR) DID Method. Kim will introduce the basics of DIDs and show how they work in action through demos of the creation/updating and resolution process in BTCR. We’ll build on this knowledge by discussing advanced features enabled by DIDs, along with a brief survey of other DID methods. By the end of the talk, you’ll be able to create and resolve your own BTCR DIDs through the live BTCR playground.

BTCR is a DID method that is based on the Bitcoin blockchain. The BTCR DID scheme uses a TX Ref-encoded transaction on the Bitcoin blockchain. The DID Description is constructed from a combination of the transaction details and an optional “continuation” DID Description, the address of which is stored in the OP_RETURN field. This could be a link to an IPFS address of a DID Description with additional entities.
